2010 Toyota Prius Cruise Control Problems

Heading westbound on I-70, taking Exit 29 off ramp from highway, I drove over uneven pavement. My traction control, ABS and brake lights illuminated, the brakes suddenly felt mushy. As I approached the stoplight at the end of the exit ramp, I questioned whether I would be able to stop. Scared me immensely. Luckily no cars were near me. I now do not have ABS, Traction Control, stability control OR regenerative braking.

My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I’m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I’m not sure when the smell first occurred.

The breaking lights, skid lights and another light associated with breaks came out and I lost the ABS abilities, the hv battery is not charging while breaking. These lights comes out randomly. Very risky especially while breaking.

The ABS, VSC/traction control, and brake system warning lights all came on at the same time in my 2010 Toyota Prius. I almost lost control of my car's braking ability. Afterwards, the hybrid system does not perform its regenerative braking/recharging any longer. And the cruise control mode doesn't work also. The DTC from the OBD2 port is C1391 - abnormal leak in the brake fluid accumulator. I found out that this issue is widespread among Gen 3 Priuses, but Toyota has not made this officially a recall campaign, but classifies it as a "customer support bulletin." But the issue is dangerous enough that it should be a recall item. I moved homes in fall of 2018, and Toyota says it mailed out a letter about this brake issue and resulting campaign, but I never received the letter. I was totally unaware that this was a safety issue, that Toyota acknowledged it, and that this safety issue with an ongoing "recall" campaign with an expiration date. Toyota denies that this is a recall issue, and will not provide this service. I would like for NHTSA to reopen and investigate this issue, and make Toyota issue a general recall campaign to resolve this dangerous safety problem with the car.

I was driving my 2010 Toyota Prius and my car started beeping when I was driving when I tried to slow down the car was not able to stop the breaking system ABS started displaying and my car started to beep and it won’t stop beeping. I did take my car to the dealer for a recalled inspection after my car broke down and I was no longer able to drive for my own safety. After I took the car to Downey Toyota for hybrid recall they didn’t tell me anything but on the document they gave me it did state that the ABS was a problem. Now my car is still not able to be used because of my own safety concerns since the vehicle won’t break when I put the brake pedal and a none stop beeping sound that won’t stop at all.

The digital speedometer display has stopped working. I can no longer see my speed or fuel gauge. I was quoted nearly $3,000 at the dealer to repair the vehicle.

MY CAR IS ACCELERATING WHILE BRAKING. WHENEVER I TRY TO BRAKE ON THE ROAD WHILE CURBING OR STOPPING AT THE TRAFFIC SIGNALS, THE CAR SKIPS/SLIDE FORWARD. IT'S GETTING WORSE ON THE RAINY TIME THOUGH.

DEFECT WITHIN THE BRAKE BOOSTER PUMP ASSEMBLY. IF THIS DEFECT OCCURS, VARIOUS WARNING LAMPS ON THE INSTRUMENT PANEL MADE ILLUMINATE, I EXPERIENCE INCREASED STOPPING DISTANCE, REDUCED HYDRAULIC PRESSURE WITHIN YOUR BRAKE SYSTEM, THE DEACTIVATION OF BRAKE ASSIST, AND/OR THE DEACTIVATION OF VEHICLE STABILITY CONTROL. TOYOTA HAS PREVIOUSLY ISSUED AT LEAST TWO SAFETY RECALLS ' D0H AND K0L ' DESIGNED TO PREVENT SIMILAR DANGEROUS OCCURRENCES. HOWEVER, HUNDREDS OF THOUSANDS OF GENERATION III PRIUS VEHICLES (2010-2015 MODEL YEARS) WERE EXCLUDED FROM THOSE SAFETY RECALLS.

AS I WAS DRIVING ON A ROAD, ABOUT 25 MPH, WHILE MY FOOT WAS ON THE ACCELERATOR PEDAL THE CAR JUST DECREASED IT'S SPEED TO A STOP AS I CONTINUALLY PUSHED MY FOOT ON THE PEDAL.

ON TWO OCCASIONS, JUNE 22, 2018 AND AUGUST 15, 2018 THIS VEHICLE SUDDENLY ACCELERATED WHILE USING CRUISE CONTROL AND TRAVELING AT SPEED ON GENERALLY FLAT, STRAIGHT, 4 LANE ROAD IN GOOD WEATHER. I HAVE ATTACHED DOCUMENTS WITH SUMMARIES OF EACH EVENT AND MAPS SHOWING ROUTE AND TERRAIN DURING THE EVENTS. HARD BRAKING SLOWED BUT DID NOT STOP THE VEHICLE EITHER TIME. BOTH TIMES, AFTER TRAVELING SOME DISTANCE WHILE BRAKING BUT CONTINUING TO ACCELERATE WITHOUT MY FOOT ON THE ACCELERATOR, THE VEHICLE MADE A THUNKING NOISE FELT THROUGH THE FLOOR OF THE CAR AND SUDDENLY STOPPED ACCELERATING. IN THE FIRST INCIDENT THIS WAS AFTER ABOUT 2 MILES, THE SECOND TIME AFTER ABOUT A MILE. AFTER EACH INCIDENT I PHONED THE LOCAL DEALERSHIP AND WAS TOLD THAT IF THEY COULD REPLICATE THE EVENT THEY MIGHT BE ABLE TO FIGURE IT OUT. I REPORTED THE EVENTS TO CORPORATE TOYOTA AND AN INVESTIGATION WAS OPENED. THE VEHICLE WAS TAKEN TO FRED ANDERSON TOYOTA OF ASHEVILLE WHERE THEY SPENT SEVERAL DAYS WITH THE CAR, INTERACTING WITH TOYOTA, WHO WAS ASKING THEM TO EXPLORE AND TEST VARIOUS THINGS RELATED TO THE DUAL PEDAL FAIL SAFE, THE COMPUTER, SNAPSHOTS OF EVENTS ON THE COMPUTER ETC. THEIR FINAL JUDGEMENT WAS THAT FLOOR MATS MAY HAVE INTERFERED, THOUGH IT WAS THE FIRST THING I CHECKED WHEN I REGAINED CONTROL OF THE CAR.

BRAKE ACTUATOR HAS FAILED. TRACTION CONTROL, ABS, BRAKE LIGHTS ILLUMINATED ON DASH. MORE EFFORT NEEDED TO ENGAGE BRAKES. THIS AFFECTS THE REGENERATIVE BRAKING AS IT NO LONGER CHARGES ON BRAKING AS IT WAS DESIGNED. CHECKED TOYOTA WEBSITE FOR RECALLS SINCE THIS IS SAFETY RELATED, AND THERE ARE NONE. WHICH IS QUITE DISTURBING. I'VE RESEARCHED PRIUS FORUMS AND THIS SEEMS TO BE AN ONGOING PROBLEM. TOYOTA ISSUED A RECALL FOR THE GENERATION 2 MODEL, HOWEVER THIS SEEMS TO BE A PROBLEM FOR GENERATION 3 MODELS AS WELL. THE PROBLEM DID OCCUR WHEN ON THE HIGHWAY TRAVELING AT 60 MPH.

I CHANGE THE BRAKE BOOSTER TWICE AND HACE THE SAME PROBLEM. MY BRAKE PEDAL LOSS OF BRAKING ABILITY OR SLIPPING BRAKES AND THE WARNING BRAKE, ABS AND TRACTION LIGHT PERMANENTLY ON, AND NO CRUISE CONTROL WORKS AT ALL

TL* THE CONTACT OWNED A 2010 TOYOTA PRIUS. WHILE PARKING THE VEHICLE, IT UNEXPECTEDLY ACCELERATED AND STRUCK ANOTHER VEHICLE BEFORE CRASHING INTO AN APARTMENT UNIT. A POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES. THE AIR BAGS DID NOT DEPLOY. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE MANUFACTURER WAS CALLED AND PROVIDED THE CONTACT WITH AN INVESTIGATOR WHO REMOVED A BOX FROM THE VEHICLE, WHICH WOULD DETERMINE IF THE FAILURE WAS DUE TO DRIVER ERROR OR A SAFETY DEFECT. THE MANUFACTURER DETERMINED THAT IT WAS DRIVER ERROR. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 53,000.

IN THE PAST YEAR I HAVE HAD 2 OCCURRENCES OF UNINTENDED ACCELERATION. THE FIRST IN FEBRUARY OF 2016. I WAS EXITING A PARKING RAMP UP HILL AND STEPPING ON THE ACCELERATOR. I WAS DRIVING STRAIGHT THEN TURNING TO THE LEFT (90 DEGREE TURN). WHEN I TOOK MY FOOT OFF THE ACCELERATOR, THE CAR CONTINUED TO ACCELERATE AND I WAS UNABLE TO GET IT SLOWED/STOPPED FOR ABOUT A BLOCK EVEN THOUGH I WAS APPLYING HEAVY BRAKE PRESSURE. THE CAR WAS REVVING AGAINST THE BRAKE PRESSURE. NO DAMAGE OR INJURIES OCCURRED. I TOOK THE CAR TO THE DEALERSHIP WHERE I PURCHASED IT (PURCHASE DATE 8/3/13). THEY CHECKED THE CAR OVER AND FOUND NO APPARENT CAUSE FOR THE ACCELERATION. I TOOK THE CAR HOME, AND IT DROVE NORMALLY UNTIL 11/26/16. ON THAT DATE I WAS DRIVING VERY SLOWLY IN A FLAT PARKING LOT, AND THE CAR BEGAN ACCELERATING WITHOUT MY PUSHING THE GAS PEDAL. I WAS DRIVING STRAIGHT AND THEN TURNING TO THE RIGHT (90 DEGREE. I GOT THE CAR STOPPED IN A FEW FEET BY PRESSING EXTREMELY HARD ON THE BRAKE. MY CAR DID NOT HIT ANYTHING. TECHNICIANS FROM THE DEALERSHIP HAVE NOT BEEN ABLE TO FIND A CAUSE AND I HAVE NOT BEEN ABLE TO GET PAST TOYOTA'S CUSTOMER SERVICE DEPARTMENT TO ESCALATE THE ISSUE FOR MORE DETAILED DIAGNOSTICS. I HAVE ATTACHED THE TIMELINE OF TRYING TO GET THE CAR DIAGNOSED AND THE ISSUE ESCALATED AS WELL AS WHY I DON'T THINK USER ERROR IS A FACTOR. *TR

I WAS IN A PARKING STRUCTURE GOING APPROXIMATELY 15 MPH WHEN I REMOVED MY FOOT FROM THE ACCELERATOR TO PRESS THE BRAKE. BEFORE I COULD GET MY FOOT TO THE BRAKE, THE CAR QUICKLY ACCELERATED. IT TOOK AT LEAST TWO ATTEMPTS AT PUSHING THE BRAKE PEDDLE BEFORE THE CAR CAME TO A STOP. AND, TO BE HONEST, THE GUARDRAIL THE CAR HIT HELPED ACTUALLY STOP THE VEHICLE. IT WAS TOTALLY UNEXPECTED AND EXTREMELY SCARY. IN HINDSIGHT, I SHOULD HAVE SUSPECTED THAT THERE MAY BE A PROBLEM WHEN I NOTICED THAT SOMETIMES WHEN APPLYING THE BRAKES TO COME TO A STOP THERE WOULD BE A FEELING OF THE BRAKES SLIPPING AND THE CAR LURCHING FORWARD A BIT. THE DEALERSHIP HAD THE CAR TOWED IN TO GET CHECKED OUT, AND I HAVE BEEN TOLD THAT THEY WILL NOTIFY TOYOTA. IN THE MEANTIME I AM CONCERNED ABOUT THE SAFETY OF THIS CAR!

BRAKE BOOSTER PUMP ASSEMBLY VEHICLE IN MOTION WHEN ON HIGHWAY WHEN LOSS OF BREAKING AND STEERING TOOK PLACE. VEHICLE LIGHTED ICONS APPEARED ON DASH ALONG WITH ALARM SOUND. (ABS) (!) (BRAKE) (SS). THIS UNSAFE CONDITION COULD HAVE BEEN AVOIDED IF NHTSA WOULD HAVE FORCED TOYOTA TO RECALL THIS DEFECTIVE PART IN 2013 WHEN TOYOTA NOTIFIED NHTSA OF THE DEFECTIVE BRAKING SYSTEM. OR TOYOTA MAILED NOTICE TO CUSTOMERS AS STATED BACK IN 2013, WHICH PREVENTION COULD PREVENT LOSS OF LIFE OR HARM. OR CLASS ACTION.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT LOW SPEEDS OVER A BUMP OR POTHOLE, THE VEHICLE WOULD SUDDENLY EXPERIENCE UNINTENDED ACCELERATION. THE CONTACT MENTIONED THAT THE FAILURE OCCURRED EVEN WHEN THE BRAKES WERE ENGAGED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 60,000.

I WAS GOING UP THE ON RAMP TO I -75 EXIT 341 IN FLORIDA WHEN I LOST ALL POWER STEERING AND BRAKING AND THE CHECK HYBRID SYSTEM LIGHT CAME ON. CARS WERE COMING AT ME AT 70 MPH AND COULD HAVE KILLED MY WIFE AND I. THIS IS THE SECOND TIME I HAVE REPORTED THE PROBLEM OF CHECK HYBRID SYSTEM LIGHT COMING ON AND LOSING ALL POWER. THIS SHOULD BE INVESTIGATED A SAP TO PREVENT SO EONE FROM BEING KILLED. *TR

ACCELERATED TO GET ON HIGHWAY. ONCE ON THE HIGHWAY THE SYSTEM HYBRID WARNING LIGHT AND OTHER WARNING LIGHTS AND AUDIO ALARMS CAME ON. WE HAD TO EXIT IMMEDIATELY BECAUSE WE LOST THE ABILITY TO MAINTAIN HIGHWAY SPEED. *TR

I AM WRITING DUE TO HAVING HAD MY 2010 TOYOTA PRIUS SELF ACCELERATE WHILE DRIVING ON FOUR OCCASIONS. THIS BEGAN OCCURRING AFTER I TOOK MY VEHICLE TO TOYOTA OF CLERMONT, FLORIDA FOR A ROUTINE SERVICE ON 3/31/2014. WHILE THE VEHICLE WAS THERE, THE DEALERSHIP ALSO PERFORMED A RECALL ON THE VEHICLE. THIS RECALL IS REFERENCED AS: TECH(S) : 20799 RECALL EOE MOTOR GENERATOR AND POWER MANAGEMENT UPDATE PERFORM SOFTWARE UPDATE FOR MG ECU AND POWER MANAGEMENT ECU AGG09A 0.7 AS OF 8/5/2014 MY VEHICLE HAS HAD UNINTENDED ACCELERATION ON 4 OCCASIONS. IN 3 OF THE 4 I KNOW IT HAS OCCURRED AS I RELEASED THE BRAKE. THIS RELEASE IS CONFIRMED BY THE FACT THAT IT IS NECESSARY TO REAPPLY THE BRAKE TO STOP THE ACCELERATION. THE 4TH OCCURRENCE MAY ALSO HAVE OCCURRED AFTER A BRAKE RELEASE. I HAVE ATTEMPTED TO RESOLVE THIS PROBLEM VIA BOTH MY LOCAL TOYOTA DEALER AND TOYOTA CUSTOMER EXPERIENCE CENTER AT 1 800 331-4331. I AM BEING TOLD THE PROBLEM IS OPERATOR ERROR. I HAVE DONE THE RESEARCH TO SEE IF THIS IS EVEN POSSIBLE. FOR ME TO APPLY THE BRAKE AND FUEL SIMULTANEOUSLY WOULD BE BOTH EXTREMELY DIFFICULT AND VERY OBVIOUS. ADDITIONALLY IF THIS DIAGNOSIS WERE CORRECT THE VEHICLE WOULD STOP ACCELERATING WHEN THE BRAKE WAS RELEASED. IN FACT THE VEHICLE ACCELERATES WHEN THE BRAKE IS RELEASED NOT WHILE THE BRAKE IS DEPRESSED. *TR

APRIL 23,2014 ENTERED A PARKING STRUCTURE, WHEN PARKING THE CAR, THE CAR ACCELERATED, WITHOUT REASON. CAR HIT AND BROKE THE PARKING BARRIER, WHICH WAS A OAK LOG. REPORTED TO TOYOTA DEALERSHIP BUT DID NOT WANT TO VIEW THE CAR, CLAIMED IT WAS PROBABLY OPERATOR ERROR. FOOT BOTH ON GAS AND BRAKE AT SAME TIME. I DO NOT DRIVE WITH TWO FEET, SAID DID NOT THINK IT WAS THAT. HE THEN REFERRED ME TO THE TOYOTA CORPORATE LINE, I HAVE A FILE WITH THEM ABOUT THE ACCELERATION ISSUE. JUST HAPPY THIS HAPPENED IN A PARKING STRUCTURE AND NOT IN A CROSSWALK SITUATION WHERE A PEDESTRIAN COULD HAVE BEEN HIT. *TR

IF THE VEHICLE HITS A POT HOLE WHILE SLOWING DOWN, THERE'S A SUDDEN LOSS OF BRAKING POWER AND THE VEHICLE MOVES A FEW FEET FORWARD. THE VSC LIGHT COMES ON AT THE SAME TIME. I'D NOTICED THIS A FEW TIMES IN THE PAST BUT WITH THE ROADS DETERIORATING AFTER A BAD WINTER, THE POT HOLES ARE BIGGER AND THIS IS VERY PROMINENT AND SCARY. GOING TO TAKE TO THE DEALER FOR INSPECTION. I FEEL IT'S DEFINITELY AN ISSUE WITH THE BRAKING SYSTEM. *TR

WHEN PARKING, MY 2010 PRIUS ACCELERATED FORWARD CAUSING IT TO GO OVER A CURB FORM DAMAGING THE FRONT BUMPER. UNEXPECTED ACCELERATION HAS CAUSED FOUR ACCIDENTS DAMAGING MY CAR. I HAVE RECORDS OF THESE REPAIRS. THE HYBRID SYSTEM WENT OUT 8/30/2013 AND IN MARCH,2014 THE BACK BRAKES FELL OFF: NO BOLTS, PADS, CALIBER, FLUID WERE IN PLACE WHEN IT WAS TOWED TO ROBBINS TOYOTA IN TEXARKANA, TX. THE FRONT RIGHT BOOSTER WAS BLOWN OUT WHILE IN THIS SHOP. MY VEHICLE THERE OVER A MONTH FOR VARIOUS REASONS. *TT

AS I WAS APPROACHING A RED LIGHT I APPLIED THE BRAKES AND THEN SHORTLY AFTER HIT A POT HOLE AND THE CAR LUNGED FORWARD AS IF ACCELERATING ON IT'S OWN. FORTUNATELY THERE WASN'T ANOTHER VEHICLE IN FRONT OF ME AS I WOULD HAVE MOST DEFINITELY REAR-ENDED IT. I ALMOST SHOT INTO THE INTERSECTION AND MOST CERTAINLY SHOT PAST THE NORMAL STOPPING SPOT FOR WAITING AT A RED LIGHT. SCARY INCIDENT TO SAY THE LEAST. *TR

I CAME TO A RED LIGHT AND WAS BRAKING AND AS IT ALMOST CAME TO A COMPLETE STOP IT JERKED FORWARD. THANKFULLY THERE WASN'T A CAR IN FRONT OF ME OTHERWISE I WOULD OF HIT IT. I'M TAKING IT IN SOON. I DON'T DRIVE IT EVERYDAY AND WHEN I DO IT'S LESS THAN A MILE. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING 30 MPH ON A BUMPY ROAD, HE DEPRESSED THE BRAKE PEDAL BUT THE VEHICLE LUNGED FORWARD. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION BUT THEY COULD NOT DETERMINE THE CAUSE OF FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE.

WHILE RETURNING FROM WORK AT 5:30 PM, 02/18/14 ON HIGHWAY 90 WEST TO ALBANY, NY, WITH CRUISE CONTROL SET TO 50 MPH, THE ACCELERATOR PEDAL GOT STUCK ON MY 2010 TOYOTA PRIUS. THE PEDAL DID NOT RETURN BACK TO ITS ORIGINAL POSITION EVEN WHEN I TURNED OFF CRUISE CONTROL. I SPONTANEOUSLY TAPPED THE ACCELERATOR PEDAL IN THE HOPE OF RELEASING BUT DID NOT YIELD ANY RESULTS AND THE VEHICLE MAINTAINED ITS SPEED. APPLYING BRAKES MADE NO EFFECT AND DID NOT CURTAIL THE CAR. IT CONTINUED TO MOVE WITH ALMOST THE SAME SPEED EVEN WHEN BRAKE PEDAL DEPRESSED. I HAD NO CONTROL ON MY CAR IN ONE OF BUSIEST FREEWAYS. I CONTINUOUSLY APPLIED THE BRAKES AND TRIED TO MERGE TO THE RIGHT MOST LANE WITH HAZARD BLINKERS ON. IT TOOK MORE THAN 5 MILES PANIC RIDE TRYING TO AVOID TRUCKS AND OTHER CARS TO MERGE TO THE RIGHT LANE. EVEN WITH THE BRAKE FULLY DEPRESSED, THE 2010 PRIUS DID NOT SLOW DOWN AND I MANAGED TO REACH THE SHOULDER LANE WHICH HAD GRAVEL & SNOW. THEN I PRESSED PARK BUTTON AND SWITCHED OFF THE ENGINE BY PRESSING THE POWER BUTTON. I COULD FEEL THE WHEELS LOCK UP BUT THE PRIUS CONTINUED TO MOVE WITH STRONG RUBBER BURNING SMELL. FINALLY, I ENGAGED THE PARKING BREAKS TO STOP IT FROM MOVING INTO THE FREEWAY. AFTER COMPLETE STOP, WITH DIFFICULTY I MANUALLY PULLED UP THE ACCELERATOR PEDAL. THIS ENTIRE ORDEAL WAS SHOCKING AND AN UNBELIEVABLE NARROW ESCAPE FROM A MAJOR CATASTROPHIC EVENT. I THANKED GOD & CALLED 911 AND THE HIGHWAY PATROL POLICE CAME TO THE SPOT AND PROMPTLY HELPED TO MOVE THE VEHICLE AND MYSELF FROM THE FREEWAY TRAFFIC. THE 2010 TOYOTA PRIUS WAS MOVED TO TOYOTA DEALER SERVICE CENTER WHERE I PURCHASED THE CAR & PERFORMED EVERY SCHEDULED MAINTENANCE SERVICE PUNCTUALLY. INCIDENTALLY THE LAST SERVICE AND CERTIFICATION WAS IN 12/2013. IT IS OBVIOUS THAT EVEN REGULAR DEALER MAINTENANCE SERVICE AND CERTIFICATION DID NOT HELP THIS VEHICLE. REPORT FILED WITH TOYOTA MOTOR CUSTOMER SERVICE. *TR

WHILE CAREFULLY PARKING MY PRIUS 2010 AT A HOSPITAL IT ACCELERATED SUDDENLY AND CRASHED OVER THE CEMENT CURB. I SAY CAREFULLY BECAUSE MY PRIUS HAD DONE THIS BEFORE BUT NOT ENOUGH DAMAGE WAS DONE TO FILE WITH INSURANCE. THERE FOLLOWED ANOTHER ACCIDENT AND ANOTHER ACCIDENT. THEN THIS EVENING WHILE DRIVING INTO MY CARPORT MY PRIUS ACCELERATED AGAIN. IT THREW MY DOG THAT WAS IN THE FRONT SEAT TO THE FLOOR BUT I WAS ABLE TO AVOID CAR DAMAGE AS I WAS GOING TO STOP. I WAS BARELY MOVING, THAT IS I STILL HAD MY FOOT ON THE ACCELERATOR,MAYBE I COULD SAY COASTING, WHEN THIS ACCELERATION SUDDENLY OCCURRED. THIS WAS THE SAME TYPE ACCELERATION THAT CAUSED ALL THE PRIOR ACCIDENTS. I HAVE REPORTED THIS TO TOYOTA... AND NOW YOU. HOPEFULLY YOU WILL HELP ME. MY PRIUS IS IN THE CARPORT. IT HAS NOT BEEN MOVED. HOWEVER, IT IS MY ONLY TRANSPORTATION. MY PRIUS' LATEST HAPPENING, BEFORE THE ONE JUST STATED, THE HYBRID SYSTEM QUIT WORKING DURING RUSH HOUR TRAFFIC ON THE INTERSTATE NEAR A BUSY INTERSECTION. THIS WAS REPAIRED BEFORE TOYOTA SENT SOME ONE TO INVESTIGATE THE PRIOR ACCIDENTS. IF MORE INFORMATION IS NEEDED JUST LET ME KNOW. THIS PRIUS ALSO HAD A BATTERY REPLACED SHORTLY AFTER IT WAS PURCHASED AS A NEW VEHICLE. THIS PRIUS HAS WHEEL RIM SCRATCHES. *TR

WHEN BRAKING, SUCH AS WHEN APPROACHING A STOP SIGN OR STOP LIGHT, IN THE PRESENCE OF BUMPS, POTHOLES, OR ROUGH/UNEVEN ROAD SURFACES, THE CAR NOTICEABLY AND FORCEFULLY "LURCHES FORWARD", AND THERE IS MOMENTARY LOSS OF CONTROL OF THE VEHICLE'S STOPPING MECHANISM. *TR...UPDATED 02-03-15 *BF *TR

CAR OCCASIONALLY UNINTENTIONALLY ACCELERATES WHEN HITTING A BUMP FOR MAYBE A SECOND. DANGEROUS WHEN IT HAPPENS AS APPROACHING A STOP SIGN OR TRAFFIC SIGNAL. HAPPENS MAYBE ONCE EVERY TWO WEEKS. *TR

VEHICLE SURGES WHEN BRAKES ARE APPLIED WHILE TRAVELING OVER RAILROAD TRACKS OR ROUGH PAVEMENT. SURGE LASTS FOR 1 TO 2 SECONDS UNTIL BRAKING RESUMES. VEHICLE BEHAVIOR CAN BE EASILY REPLICATED. *TR

I HAVE A 2010 TOYOTA PRIUS THAT REALLY HAS ME CONCERNED. TWICE RECENTLY WHEN APPLYING THE BRAKES, IT HAS LUNGED FORWARD AND I WAS FORCED TO PUNCH THE BRAKES VERY HARD WITH BOTH FEET TO MAKE IT STOP. IT REALLY SCARED ME. LUCKILY THERE WAS NOBODY IN FRONT OF ME OR I WOULD HAVE HAD AN ACCIDENT. I TOOK IT TO THE DEALER (WALKER TOYOTA IN MIAMISBURG, OH) TO HAVE IT CHECKED OUT. THE SERVICE DEPARTMENT LOOKED BACK AT THE COMPUTER ON THE CAR AND SAW TWO INSTANCES WHERE THE BRAKE AND ACCELERATOR WERE PRESSED AT THE SAME TIME. SO NOW THEY ARE TRYING TO TELL ME IT IS USER ERROR. THEY SAID I MUST HAVE INADVERTADLY HIT THE ACCELERATOR PEDAL WHILE I WAS BRAKING. NO I DID NOT!!! I HAVE OWNED THIS CAR FOR OVER THREE YEARS AND THIS HAS NEVER HAPPENED BEFORE. NOW IT HAS HAPPENED TWICE IN THE LAST TWO MONTHS. I DON'T THINK SO... I CALLED TOYOTA CORPORATE AND THEY ADVISED ME TO GET A SECOND OPINION. SO NOW I AM TAKING IT TO VOSS TOYOTA IN BEAVERCREEK. I ALSO NOTICED RECENTLY THAT MY GAS MILEAGE HAS DROPPED SIGNIFICANTLY IN THE LAST SIX MONTHS. IT'S MUCH WORSE THAN IT'S EVER BEEN SINCE I HAVE OWNED IT. I'M NOT SURE IT IT IS RELATED OR NOT??? *TR

I HAVE A 2010 TOYOTA PRIUS THAT REALLY HAS ME CONCERNED. TWICE RECENTLY WHEN APPLYING THE BRAKES, IT HAS LUNGED FORWARD AND I WAS FORCED TO PUNCH THE BRAKES VERY HARD WITH BOTH FEET TO MAKE IT STOP. BOTH TIMES I WAS ON CITY STREETS GOING ABOUT 35 MPH. IT REALLY SCARED ME. LUCKILY THERE WAS NOBODY IN FRONT OF ME OR I WOULD HAVE HAD AN ACCIDENT. I TOOK IT TO THE DEALER TO HAVE IT CHECKED OUT AND AM AWAITING THE VERDICT. *TR

ON MULTIPLE OCCASIONS, I HAVE EXPERIENCED ISSUES WITH THE CAR SUDDENLY ACCELERATING WHILE I'M PRESSING THE BRAKES. SPECIFICALLY, THIS APPEARS TO OCCUR WHEN BRAKING ON UNEVEN SURFACES (IE CONSTRUCTION AREAS, POT HOLES, ETC.). THIS CAN OBVIOUSLY BECOME A DEADLY SITUATION IF ONE IS TRYING TO STOP THE VEHICLE AND WITH THIS PROBLEM RUN INTO THE CAR/VEHICLE AHEAD. MOST RECENTLY THIS OCCURRED ON THE SURFACE STREETS IN LOW SPEED, IN TRAFFIC. IT FEELS LIKE THE CAR LURCHES AHEAD WHILE APPLYING THE BRAKE. I WAS TOLD BY THE SERVICE PEOPLE AT TOYOTA THAT I WAS MAKING THIS UP. I CAN RECREATE IT GIVEN THE RIGHT SURFACE. *TR

TODAY, 1/21/2013 AT APPROXIMATELY 245PM WHILE DRIVE BACK FROM DISNEY WITH MY FAMILY ON THE FLORIDA TURNPIKE(MILE POINT MARKER 294 NB) AT APPROXIMATELY 65-70 MPH OUR 2010 PRIUS SUDDENLY LOST POWER AND "CHECK HYBRID SYSTEM" CAME ON. MIND YOU I WAS TRAVELING ON A MAJOR ROAD WHEN THE CAR SUDDENLY KEPT DECREASING IN SPEED AND I JUST TURNED ON TO THE MEDIAN AND THE CAR ROLLED TO A STOP. LUCKILY THERE WAS A FLORIDA SAFETY PATROL BEHIND ME WHO PUT ON HIS FLASHING LIGHTS UNTIL I WAS SAFELY OFF THE TURNPIKE. CAR WOULD NOT RESTART AND HAD TO BE TOWED. CAR ARRIVED AT XXX(DEALER) TOYOTA AT 502PM AND I AM AWAITING A CALL BACK ON THE PROBLEM. THIS IS A SAFETY ISSUE. ALSO, THERE WAS NO WARNING BEFORE THE CAR FAILED. THANK YOU.

TRAVELING ON PARKWAY WHEN WE WERE APPROACHING A VEHICLE GOING SOUTH DOWN AT APPROXIMATELY 55 WE WERE TRAVELING 72 WITH CRUISE CONTROL ENGAGED, I TAPPED THE BRAKES TO TRY AND SLOW AND NOTHING HAPPENED I THEN HELD THE BRAKE PEDAL DOWN FOR MORE THAN 15 SECONDS WITH NO SUCCESS, TRIED TO DISENGAGE THE CRUISE BY PULLING BACK ON THE HANDLE ON THE STEERING WHEEL AND STILL IT WOULD NOT DISENGAGE, WE STRUCK THE TRUCK AT 72 MPH ONLY BECAUSE WE HAD NO WHERE ELSE TO GO AND THE VEHICLE WOULD NOT DISENGAGE CRUISE. THE CRUISE CONTROL LIGHT WAS STILL ILLUMINATED AFTER THE VEHICLE CAME TO REST AFTER IMPACT AND THE VEHICLE BRAKES STILL DID NOT APPEAR TO FUNCTION, THIS VEHICLE WAS A TOYOTA LEASE AND WAS TOLD MULTIPLE TIMES BY TOYOTA THAT THE ISSUES WAS RECALLED BY TOYOTA AND THAT THIS VEHICLE HAD THE RECALL PERFORMED. *TR

THE UNINTENDED ACCELERATION ACCIDENT HAPPENED ON 7/18/2012, ~6:20 PM AT COMPANY'S PARKING LOT. I BACKED MY 2010 PRIUS SLOWLY. THEN I SAW A CAR COMING ON MY WAY. BUT BEFORE I TOOK ANY ACTION, THIS PRIUS SUDDENLY STARTED ACCELERATING, IT WENT WILDLY, AND TURNED MORE THAN 360 DEGREE BACKWARD IN THE PARKING LOT IN JUST A FEW SECONDS. SINCE THE CAR PARKED BETWEEN A BUILDING AND A SLOP, FROM THE FRONT MIRROR, FIRST, I SAW THE BUILDING WALL AND GLASSES, THEN I SAW THE SLOPE, THEN I SAW A CAR PARKED CLOSE TO MY CAR: NO! DON'T HIT THAT CAR! THAT IS THE LAST THING I REMEMBER. BECAUSE OF THE FAST TURNING OF THE CAR AND BECAUSE I WAS SO TERRIBLY SCARED, I LOST CONSCIOUS AFTER THAT UNTIL THE PRIUS HIT THE TRUCK AND BOUNCED BACK AND STOPPED BY ITSELF. AFTER A FEW SECONDS, I WOKE UP AND REALIZED: I AM STILL ALIVE. I GOT OFF THE CAR AND SAW PRIUS PASSED THE TWO CURBS AND HIT THE TRUCK. THE TWO TIRES ON THE DRIVER SIDE GOT FLAT BECAUSE THEY PASSED THE CURB VERY FAST. I WAS SO SCARED THAT I COULDN'T RECALL OF ANYTHING FOR A FEW DAYS UNTIL WEEKEND. WHY DID THE CAR LOSE CONTROL? ONE MAY ARGUE THAT I STEPPED ON THE ACCELERATOR. THIS COULD HAPPEN TO NEW DRIVERS, BUT NOT TO ME BECAUSE I HAVE BEEN DRIVING FOR SO MANY YEARS AND ALWAYS A GOOD DRIVER. MANY TIMES I SAW A CAR ON MY WAY WHEN I WAS BACKING, I ALWAYS STOPPED RIGHT AWAY. AND I WAS HEALTHY IN A NORMAL DAY IN NORMAL MODE, ALERT AS USUAL. WHY WOULD I STEP ON ACCELERATOR WHEN BACKING? EVEN IF I MIS-STEPPED ON THE ACCELERATOR, I CAN ALWAYS SWITCH TO BRAKE RIGHT AWAY. BUT I COULD?T DO ANYTHING ABOUT THE CAR ON THE DAY. IT WAS OUT OF CONTROL COMPLETELY. AFTER I LOST CONSCIOUS, MY HANDS WERE OFF THE STEERING WHEEL AND MY FOOT DIDN'T STEP ON ANYTHING, THE CAR DIDN'T SLOW DOWN BUT STILL MOVED FAST AND PASSED TWO CURBS EASILY. SUCH A MANIPULATION CAN ONLY BE DONE WHEN THE CAR IS IN ACCELERATION, AND BY ITSELF. PLEASE INVESTIGATE IT ASAP! *TR

THE DYNAMIC RADAR CRUISE CONTROL SYSTEM SUDDENLY APPLIES BRAKES WHILE, OR SOON AFTER, PASSING A LARGE TRUCK (18 WHEELER). HAPPENS RARELY. BUT WHEN IT DOES HAPPEN, IT IS ALWAYS WHILE, OR SOON AFTER, SLOWLY PASSING A LARGER TRUCK ON AN INTERSTATE AND TRAVELING ABOUT 70 MPH. WHEN IT DOES OCCUR, IT NORMALLY OCCURS WHEN THE FRONT OF THE PRIUS IS SLIGHTLY BEHIND THE FRONT OF THE TRUCK (IN THE IMMEDIATE LANE TO MY RIGHT) WHERE THE TRUCK SHOULD BE OUTSIDE THE RANGE OF THE RADAR. THE LAST TIME, THOUGH, THE PRIUS WAS WELL IN FRONT OF THE TRUCK, THERE WAS NO VEHICLE IN FRONT OF ME. AND, YES, THERE WAS NO DIRT, SNOW, ETC. ON THE FRONT OF THE CAR THAT MIGHT AFFECT THE OPERATION OF THE RADAR. *TR

2010 PRIUS 4 DR HATCHBACK THE SPEED CONTROL ON MY PRIUS USES RADAR TO SPEED UP AND SLOW DOWN. IF I COME UP ON A CAR DOING 45 MPH AND I'M AT 55, THE VEHICLE SLOWS DOWN. WHEN I TURN TO THE OTHER TRAFFIC LANE, AND THE LANE IS CLEAR THE CAR ACCELERATES RAPIDLY. ON A NUMBER OF OCCASIONS I HAVE BRAKED TO DISENGAGE THE CRUISE CONTROL, I FELL LIKE I DON'T HAVE CONTROL OF THE CAR. THE FIX: ADJUST THE COMPUTER SO SPEED ACCELERATION IS SLOWER. I THINK IT IS A CRASH HAZARD. *TR

WE WERE BACKING DOWN OUR DRIVEWAY IN OUR 2009 TOYOTA PRIUS. AS WE APPROACHED THE STREET OUR CAR SUDDENLY MADE A LOUD WHINING NOISE AND STARTED ACCELERATING BACKWARDS. BEFORE WE COULD DO ANYTHING, WE BACKED INTO THE CAR PARKED ACROSS FROM OUR DRIVEWAY. AFTER WE COLLECTED OURSELVES, WE DECIDED TO MOVE THE CAR OUT OF THE STREET INTO OUR DRIVEWAY. THE SUDDEN ACCELERATION HAPPENED AGAIN, BUT THIS TIME MY HUSBAND REACHED OVER AND HIT THE PARK BUTTON AND WE STOPPED BEFORE WE HIT ANYTHING. I HAVE DRIVEN OUR OTHER TWO CARS DOWN OUR LONG DRIVEWAY SINCE, AND WE ONLY USE THE ACCELERATOR TO START THE CAR MOVING. AFTER THAT, WE ARE BRAKING ALL THE WAY DOWN THE DRIVE. THE ACCELERATION OCCURRED NEAR THE STREET WHERE WE PAUSE TO CHECK ON THE TRAFFIC. NOW THAT I HAVE CHECKED MYSELF WITH OUR OTHER CARS, I AM SURE I DID NOT HAVE MY FOOT ON THE ACCELERATOR PEDAL AT THE BOTTOM OF THE DRIVE, AS I BRAKE ALL THE WAY DOWN. OUR PRIUS IS OVER AT THE DEALER, AND WE HAVE FILED A COMPLAINT WITH TOYOTA. WE ARE AFRAID OF THE CAR. WE DID HAVE THE CAR FIXED AT THE RECALL. *TR

TOYOTA PRIUS 2010, MY PROBLEM IS SOMETIMES THE GAS PEDAL DOES NOT RELEASE WHEN TRYING TO STOP, I HAVE FOUND THAT BY RELEASING THE BRAKE PEDAL THE THROTTLE RELEASES, THIS ALWAYS HAPPENS UNDER THE SPEED OF 40 MPH. THIS PROBLEM IS ALWAYS RANDOM, AND YOU NEVER KNOW WHEN IT WILL HAPPEN, IT HAS HAPPENED ABOUT 30 TIMES SO FAR, THIS STARTED ABOUT 6 MONTHS AGO. IS THIS PROBLEM PART OF THE RECALL. *TR

THE CRUISE CONTROL DISENGAGE MECHANISM IN MY 2010 TOYOTA PRIUS DOES NOT DISENGAGE QUICKLY ENOUGH WHEN DEPRESSING THE BRAKE. I HAVE TO PRESS THE BRAKE HARDER THAN ANY PRIOR VEHICLES I HAVE OWNED TO KILL THE CRUISE CONTROL AND IF I RELEASE THE BRAKE BEFORE THE CRUISE CONTROL IS RELEASED THEN THE CAR LURCHES FORWARD. THIS IS A SAFETY ISSUE WITH THIS VEHICLE AND I CALLED TOYOTA AND THEY SAID THAT THERE IS NO SAFETY ISSUE AND WOULD NOT SPEAK TO ME FURTHER ABOUT IT WITHOUT GOING TO THE DEALER. THE DEALER HAD ALREADY TOLD ME THAT IT IS OPERATING NORMALLY AND THAT THIS IS HOW THE 2010 NEW PRIUS MODEL YEAR OPERATES. I HAVE A 2006 PRIUS AS WELL AND THE CRUISE DISENGAGES NORMALLY. MANY OTHER PEOPLE HAVE EXPERIENCED THIS ISSUE AND HAVE DOCUMENTED THEIR EXPERIENCES ON THE FORUM PRIUSCHAT.COM . THEY HAVE EVEN FIXED THE PROBLEM THEMSELVES BY MOVING THE CRUISE CONTROL DISENGAGEMENT CLOSER TO THE TOP OF THE BRAKE PEDAL. OTHERS HAVE REPORTED THAT THEY CAN DEPRESS THEIR BRAKES AND SLOW DOWN THE VEHICLE WITHOUT THEIR BRAKE LIGHTS COMING ON AND THIS IS THE SAME PROBLEM BECAUSE THE BRAKE LIGHTS AND CRUISE CONTROL KILL SWITCH ARE LINKED TOGETHER. *TR

CASE OF SUDDEN UNINTENDED ACCELERATION IN A NEW 2010 TOYOTA PRIUS: I WAS PARKING MY CAR IN A PULL-IN PARKING SPOT IN AN OFFICE BUILDING PARKING LOT. WHILE STRAIGHTENING THE CAR OUT IN THE SPOT, IT SUDDENLY ACCELERATED OUT OF CONTROL AND JUMPED A CURB IN FRONT OF LANDSCAPED SHRUBBERY. A LARGE WOODY BUSH, AND SOFT DIRT STOPPED THE VEHICLE. NO ONE ELSE WAS INVOLVED IN THE ACCIDENT. THE CAR HAS ONLY 2200 MILES ON IT. THE CAR IS CURRENTLY BEING HELD BY THE DEALER, TOYOTA SCION OF EATONTOWN, NJ. *TR

MY 2010 TOYOTA PRIUS LOSES BRAKING ABILITY AND LUNGES FORWARD WHILE BRAKING ON ANY UNEVEN SURFACE I.E. POTHOLE, MANHOLE COVER, BUMP METAL PLATE OR STRIP, ETC... THIS HAS LEAD TO SEVERAL NEAR MISS COLLISIONS AND DUE TO THE AMOUNT OF TIME I SPEND IN THE CAR HAPPENS AN AVERAGE OF 3 TIMES PER DAY. BECAUSE I FEAR FOR MY OWN SAFETY I DO NOT ALLOW PASSENGERS IN MY CAR AND I WILL NOT LET ANYONE ELSE DRIVE MY CAR. I'VE HAD TO ADJUST MY DRIVING TO TRY AND COMPENSATE FOR NO BRAKING ABILITY AT ANY GIVEN TIME. I HAVE NOW REPORTED THIS PROBLEM TO MY DEALER TOYOTA OF MERRILLVILLE IN PERSON 3 TIMES AND OVER THE PHONE ON SEVERAL OCCASIONS AND EACH TIME I WAS TOLD THEY WERE UNABLE TO DUPLICATE THE PROBLEM AND THEREFORE THERE WAS NO FIX THEY COULD OFFER. THEY ALSO TELL ME THAT I AM THE ONLY CUSTOMER REPORTING THIS TYPE OF CONCERN BUT I HAVE BEEN ABLE TO CONNECT WITH MANY PRIUS OWNERS EXPERIENCING THIS LOSS OF BRAKING WHILE OVER UNEVEN PAVEMENT. I BELIEVE TOYOTA IS DOWNPLAYING THIS PROBLEM AT THE RISK OF PUBLIC SAFETY. *TR

I HAVE A 2010 TOYOTA PRIUS THAT HAS THE PROBLEM WITH THE BRAKES SOMETIMES DIS-ENGAGING WHEN THE CAR GOES OVER UNEVEN OR SLIPPERY SURFACES. TOYOTA WAS UNABLE TO FIX THIS PROBLEM AFTER I BROUGHT IT IN FOR THE RECALL. THE PROBLEM REMAINS SO I AM STUCK DRIVING AN UNSAFE CAR. *TR

AT ABOUT 7:45 AM SUNDAY MAY 23, I WAS DRIVING WEST ON HAMBURG TURNPIKE IN WAYNE, GENTLY ACCELERATING TO GET BETTER MILEAGE, THE LIGHT AT BERDAN AVE AND HAMBURG HAD JUST TURNED GREEN, SO I ACCELERATED SLOWLY TO ABOUT 40 MPH. AT THIS POINT, I HEAR A SHRIEKING BEEP AND THE CAR LURCHES FORWARD AS THE BRAKES WERE APPLIED. THE DASH LIGHTS UP WITH THE USUAL MESSAGE SQUARE AND THE WORD BRAKE! IN THE BOX. I LOOK IN ALL DIRECTIONS AND SAW NOTHING UNTIL I BOUNCED OVER THE CONSTRUCTION PLATES. THE BOX WAS GONE, AND THE CAR RESUMED NORMAL OPERATION. I WAS PUZZLED. I THOUGHT IT COULD BE THE PLATES. I CHECKED WITH MY SON AND HE REMINDED ME THAT IN THE MODEL 5 WE HAVE RADAR CRASH AVOIDANCE. UPON FURTHER REVIEW I WANTED MORE INFORMATION. I TOOK MY SON, AND A CAMERA, AND DROVE THE ROUTE AGAIN. EUREKA! IN ALL THREE ATTEMPTS, THE BRAKES WERE APPLIED. I HAVE PICTURES OF THE DASH, AND THE PLATES. DID THE CAR PERFORM CORRECTLY? THE SECOND PLATE IS NOT FLUSH TO THE ROAD AND STICKS OUT TO THE LEFT. I THINK OTHER DRIVERS NEED TO BE AWARE OF THIS POSSIBILITY SO THEY DO NOT PANIC WHEN IT HAPPENS. THE CRASH AVOIDANCE SYSTEM COULD HAVE BEEN DOING ITS JOB CORRECTLY. I CONTACTED WAYNE POLICE ABOUT THE INCIDENT AND THE DISPATCHER SAID AFTER CONSULTATION ' IT IS A COUNTY ROAD, CALL THE PASSAIC COUNTY ROAD DEPARTMENT. MY CAR COMPUTER WILL HAVE RECORDED ALL 3 INCIDENTS. THE THIRD WAS NOT AS BIG A JOLT BECAUSE THE DRIVER AHEAD OF ME HAD SLOWED CONSIDERABLY WHEN HE SAW THE PLATES. THERE IS A WARNING SIGN THAT IS BEYOND THE PLATES IN THE PICTURE. LET ME KNOW IF ANYONE IN SERVICE IS INTERESTED IN THE INFORMATION SINCE THIS IS A NEW FEATURE AND I KNOW AS A COMPUTER PROGRAMMER OF SOME 40+ YEARS THAT A SYSTEM DOES NOT ALWAYS GET TESTED FOR ALL POSSIBLE EVENTS. I ALSO CANNOT BELIEVE THAT UNLIKE NYC WHERE THERE MUST BE NO BUMPS OR RAISED PLATES DURING CONSTRUCTION THAT PASSAIC COUNTY ALLOWS THESE PLATES TO BE INSTALLED WITHOUT BEING FLAT OR ASPHALTED AROUND THE EDGE. *TR

WHILE DRIVING ON I-430 IN WEST LITTLE ROCK YESTERDAY, I HAD THE CRUISE CONTROL SET ON 65 MPH. AS I APPROACHED SLOWER TRAFFIC AHEAD, I SLOWED THE CAR TO 60MPH USING THE BRAKES. I ASSUMED THAT THE CRUISE CONTROL ON MY CAR HAD AUTOMATICALLY DISENGAGED AT THIS POINT AND I LET OFF THE BRAKES. THE CRUISE CONTROL THEN CAUSED THE CAR TO ACCELERATE BACK UP TO 65MPH AS IT NEVER DISENGAGED BY USING THE BRAKES. THIS WAS ESPECIALLY DANGEROUS SINCE IT HAPPENED NEAR THE CREST OF A HILL AND CAUSED MY VEHICLE TO NO LONGER BE AT A SAFE FOLLOWING DISTANCE BEHIND THE SLOWER CAR IN FRONT OF ME. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING APPROXIMATELY 30 MPH AND ATTEMPTING TO ACCELERATE, THE VEHICLE WOULD NOT INCREASE IN SPEED. THE CONTACT CONTINUED TO APPLY CONTINUOUS, STEADY PRESSURE TO THE ACCELERATOR UNTIL IT FINALLY BEGAN TO ACCELERATE. THE CONTACT STATED THE FAILURE WOULD OCCUR SPORADICALLY, MOST OFTEN WHEN ACCELERATING FROM A COMPLETE STOP. THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE UNAVAILABLE.

TOYOTA 2010 PRIUS, FOR 5 MONTHS IT HAS BEEN PERFECTLY GOOD. BUMPS OR UNEVEN ROADS, NO PROBLEM, GOT THE PRIUS COMPUTER UPDATE 2-33 MONTHS AGO. APRIL 30 - DRIVING ON ROAD WITH ROUGH SURFACE FOR REPAVING AND WITH SEWER COVERS STICKING ABOVE SURFACE, AND NO PROBLEM FOR 2 MILES THEN HIT A REPATCHED HOLE AND THE CAR JERKED AHEAD QUICKLY BUT MY BRAKING SLOWED IT DOWN IMMEDIATELY. THE ENTIRE PROCESS TOOK 1 SECOND. LUCKILY I HAD GOOD REFLEXES. SCARY BUT THE BRAKE WORKED WELL. SINCE THAT INCIDENT - 1 DAY, CAR IS FINE. *TR

I MADE A NHTSA COMPLAINT ON 1/27/10 FOR ABS/UNINTENDED ACCEL INCIDENTS IN MY PRIUS2010. SUPPOSEDLY TOYOTA CORRECTED THE PROBLEM ON 2/11/10. ON 4/20/10 @ 12:50 PM, MY PRIUS ACCELERATED DANGEROUSLY AS I WAS COMING TO A COMPLETE STOP ON A SLIGHT INCLINE. THE CAR SHOT FORWARD THROUGH A RED LIGHT ON A BUSY BALTIMORE ARTERIAL. I WAS BRAKING THE CAR AND TRYING TO TURN IT TO AVOID HITTING A CONCRETE WALL OR CARS IN THE OPPOSITE LANES. I TURNED VERY SHARPLY,UNABLE TO BRAKE THE CAR; I FEARED IT MAY ROLLOVER. MY FOOT WAS ON THE BRAKE THE WHOLE TIME. I HOPPED A CURB ON THE MEDIAN AND CLIPPED A TRAFFIC SIGN. I THEN PARKED THE CAR AND PHONED THE POLICE. IT WAS AMAZING NO ONE GOT HURT OR KILLED. SINCE THIS INCIDENT OCCURRED AFTER TOYOTA SAID THEY FIXED THE PROBLEM, I DO NOT TRUST THEM OR MY CAR. I WANT A REFUND FOR THIS CAR, I WILL NOT DRIVE IT AGAIN:IT IS A DEATH MACHINE. *TR

I HAVE A NEW 2010 PRIUS WITH LESS THAN 1K MILES. ON 4-9-10 WHILE PULLING INTO A PARKING SPOT I EXPERIENCED A SIMULTANEOUS LOSS OF BRAKING COMBINED WITH UNINTENDED SURGE OF ACCELERATION. MY PRIUS JUMPED THE CURB THAT WAS PERPENDICULAR TO THE PARKING SLOT AND STOPPED AS IT SLAMMED INTO A BRICK BUILDING ABOUT 8 FEET BEYOND THE CURB. I UTILIZED MY SAFETY CONNECT BUTTON TO RECORD THE TIME OF THE ACCIDENT AND HAD THE VEHICLE TOWED TO THE DEALER. I CONTACTED TOYOTA CUSTOMER EXPERIENCE CENTER AND NOW HAVE A CASE #. I WAS TOLD THAT SOMEONE WOULD CONTACT ME WITHIN 2 BUSINESS DAYS. I AM NOT AT ALL COMFORTED BY THIS VERY SCARY INCIDENT. I WOULD JUST LIKE TO HAVE MY 2005 PRIUS BACK AS I NEVER HAD ANY PROBLEMS WITH IT. I AM SEEING THAT MY PROBLEM IS NOT UNIQUE BASED ON MANY SIMILAR PROBLEMS ON THIS NHTSA COMPLAINT SITE. *TR

2010 PRIUS WITH ABOUT 14,500 MILES DRIVING ON SMOOTH, WET, PAVED ROAD 20 MILES AN HOUR ON A CURVE. NEITHER FOOT WAS NOT ON A PEDAL - CAR WAS COASTING FOR SEVERAL SECONDS AS EXPECTED, SLOWLY DECELERATING. IN THE MIDDLE OF THE CURVE, WITH BOTH FEET STILL NOT ON EITHER GAS OR BRAKE, I FELT AND HEARD A NOTABLE SURGE OF HARD ACCELERATION DESPITE BOTH FEET BEING OFF THE GAS AND BRAKE. MY WIFE IN THE PASSENGER SEAT ALSO NOTICED THE SURGE. I IMMEDIATELY BRAKED HARD. THE CAR SLOWED SAFELY, AND THE UNREQUESTED ACCELERATION SEEMED TO STOP AS SOON AS I ENGAGED THE BRAKE PEDAL. NOTHING WAS TOUCHING THE ACCELERATOR BEFORE THE SURGE, DURING THE SURGE, OR WHEN THE SURGE ENDED AS I BRAKED - NOT A FLOOR MAT, NOT A STRAY OBJECT, NOT MY FOOT. THIS IS THE FIRST TIME WE HAVE EXPERIENCED THIS EXACT PATTERN OF SYMPTOMS. IN THE PAST, BEFORE THE BRAKE SOFTWARE RECALL WAS DOWNLOADED TO OUR CAR, WE HAD MANY EPISODES OF TEMPORARY LOSS OF BRAKING POWER ON BUMPY ROADS. AT LEAST ONE OF THOSE PRIOR EPISODES HAD UNEXPLAINED ACCELERATION ACCOMPANY THE TEMPORARY BRAKING FAILURE ON A BUMPY ROAD. TODAY'S INCIDENT WAS VERY DIFFERENT - I WAS NOT BRAKING, AND THE ROAD WAS NOT BUMPY. NOTE THAT THE 2010 PRIUS IS NOT ON THE RECALL LISTS FOR THE ACCELERATOR MODIFICATIONS, AND THAT A STICKY ACCELERATOR WOULD NOT EXPLAIN THIS BEHAVIOR. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 65 MPH WITH THE CRUISE CONTROL ACTIVATED. THERE WAS PRESSURE APPLIED TO THE BRAKE PEDAL WITH A SUDDEN INCREASE OF ACCELERATION UP TO 70 MPH. THE FAILURE OCCURRED ON ONE OCCASION. THE FAILURE MILEAGE WAS 13,364. THE CURRENT MILEAGE WAS 13,647.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHEN THE CONTACT SHIFTED INTO DRIVE GEAR, THE VEHICLE SUDDENLY ACCELERATED IN REVERSE. THE BRAKES WERE APPLIED BUT DID NOT STOP THE VEHICLE, THE CONTACT PUSHED THE POWER BUTTON WHICH TURNED OFF THE VEHICLE AND STOPPED THE ACCELERATION. THE VEHICLE WAS TAKEN TO THE DEALERSHIP WHERE NHTSA RECALL# 10V039000 SERVICE BRAKES, AIR ANTILOCK CONTROL UNIT/MODULE WAS PERFORMED ON THE VEHICLE. THE CONTACT WAS CONCERNED THAT THE DEFECT WAS ELECTRICAL OR A DEFECT IN THE COMPUTER. THE APPROXIMATE CURRENT AND FAILURE MILEAGES WERE 5,300.

TL * THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE FIRST TIME SHE EXPERIENCED SUDDEN ACCELERATION WAS ON JANUARY 15, 2010. WHILE STOPPED AT THE RED LIGHT WITH HER FOOT ON THE BRAKE THE VEHICLE SUDDENLY ACCELERATED. SHE PUT THE GEAR IN NEUTRAL AND THE VEHICLE STOPPED, AS SOON SHE TOOK THE GEAR OUT OF NEUTRAL THE VEHICLE ACCELERATED AGAIN. SHE EXPERIENCED THE FAILURE FIVE TIMES. SHE TOOK THE VEHICLE TO THE DEALER FEBRUARY 13 2010 THE DEALER REPLACED ACCELERATOR PEDAL AND RESET THE ACCELERATOR COMPUTERIZED SYSTEM. AND ON MARCH 18, 2010 SHE EXPERIENCED THE FAILURE AGAIN WHILE STOPPED AT THE RED LIGHT THE VEHICLE CONTINUED TO ACCELERATE. THE CONTACT STATED SHE WILL TAKE THE VEHICLE BACK TO THE DEALER. THE CURRENT FAILURE MILEAGE WAS 2,000 AND THE CURRENT MILEAGE WAS 4,200.

MY 2010 PRIUS WAS DELIVERED ON DECEMBER 17, I TOOK IT ON TWO LONG ROAD TRIPS AND USED MY CRUISE CONTROL ON BOTH TRIPS. ON BOTH TRIPS WITH CRUISE CONTROL ON THERE WAS A SURGE OF ACCELERATION. NOTHING STUCK AND WHEN I APPLIED THE BRAKES THE CRUISE CONTROL CUT OFF AND THE CAR SLOWED. I HAVE EXPERIENCED THIS ONE OTHER TIME AND AGAIN IT WAS INTERSTATE DRIVING WITH CRUISE CONTROL ON. *TR

MY 2010 PRIUS WAS "REPAIRED" LAST MONTH. IT INTERMITTENTLY ACCELERATES WITHOUT MY PROMPTING AFTER HITTING A BUMP. THIS ACCELERATION IS AS INTENSE AS THE CAR SEEMS TO ALLOW, AS IF THE PEDAL WERE TO THE FLOOR OR WORSE, AND PERSISTS FOR AT LEAST ONE SECOND AND HAS NOT SUBSIDED SINCE THE ABS ACTUATOR ECU WAS UPDATED IN THE RECALL APPOINTMENT. THIS ACCELERATION IS TERRIFYING AS IT CAN'T BE ANTICIPATED AS IT DOES NOT HAPPEN EVERY TIME I HIT A BUMP, AND CAN'T BE SUPPRESSED BY THE BRAKING SYSTEM. I HAVE ON SEVERAL OCCASIONS BEEN SAFELY COASTING TO A STOP WITH THE BRAKES ON AND EXPERIENCED THIS PROBLEM. IN A FEW CASES THIS ACCELERATION ALMOST CAUSED ME TO HIT THE CAR IN FRONT OF ME AT STOP LIGHTS. I NEVER DID EXPERIENCE THE SYMPTOMS DESCRIBED BY TOYOTA RELATING TO THE DELAYED BRAKING PROBLEM, BUT I FEAR THIS PROBLEM AS MUCH OR MORE. *TR

I HAVE BEEN HAVING TWO ISSUES WITH THE 2010 PRIUS SINCE I BOUGHT IT ON 29TH DEC 2009. 1. UNABLE TO STOP AND SUDDEN ACCELERATION WHEN HITTING ROUGH /UNEVEN ROAD CONDITION AND TRYING TO STOP AND CONTROL THE VEHICLE. 2. UNABLE TO STOP SOME TIMES WHEN DRIVE AT CITY SPEED LIMIT AND GOING BETWEEN SLOW AND STOP AND SLOW AND FAST AND SLOW KIND OF DRIVING, SOMETIME WHEN PRESSING BRAKE, INSTEAD OF DECELERATING IT START TO ACCELERATE AND TAKES LONGER TO STOP. I HAVE ALREADY BEEN TO TOYOTA DEALERSHIP 3 TIMES OVER THIS ISSUE. FIRST TIME THEY FIXED BRAKE ISSUE. SECOND TIME IT WAS RECALL THAT THEY TOLD WILL FIX THE PROBLEM I AM HAVING. 3RD TIME THEY SAID THEY CAN REPRODUCE THE PROBLEM. BUT I KNOW I FEEL THE ISSUE SOMETIME. AND I CAN NOT JUST LEAVE THE CAR WITH THEM FOR DAYS TO INVESTIGATE AND I CAN CHANGE MY DRIVING PATTERN OR BEHAVIOR EITHER FOR THIS CAR. *TR

THE VEHICLE HAS NOT BEEN REPAIRED AT THIS TIME. THE CURRENT AND FAILURE MILEAGES WERE 11,000.

MY 2010 PRIUS HAS HAD THESE PROBLEMS, WHICH ARE NOT BEING ADDRESSED BY TOYOTA. 1)GAS PEDAL STOPPED WORKING AT ALL ON TWO OCCASIONS GOING 20-30 MILES AN HOUR. HAD TO PULL OVER, TURN CAR OFF, RESTART IT. THEN IT WORKED. HASN'T HAPPENED AGAIN. 2)CRUISE CONTROL IS VERY DIFFICULT TO STOP WITH BRAKE. THIS IS CONSISTENT. I HAVE STOPPED USING THE CRUISE CONTROL BECAUSE IT HAS ALMOST CAUSED ME TO REAR END ANOTHER VEHICLE ON SEVERAL OCCASIONS. *TR

WHEN BRAKING, ALL OF A SUDDEN THE CAR LURCHES FOR A SECOND OR SO, AS IF ON ICE. THIS HAPPENED 3 TIMES IN DIFFERENT CIRCUMSTANCES, ONCE NOT RELATED TO A POTHOLE. TOYOTA DEALER IN AVON CT APPLIED THE CORRECTION TO THE SOFTWARE, AND THE NEXT WEEK (LAST WEEK) THE SAME THING HAPPENED AGAIN, WHEN I HIT A WIDE, BUT NOT DEEP POTHOLE WHILE BRAKING, JUST BEFORE STOPPING AT THE END OF A HIGHWAY EXIT RAMP. IN THIS SITUATION, IT WAS FORTUNATE THAT NO CAR WAS IN FRONT OF ME AT THE LIGHT. ADDITIONALLY I HAD A PROBLEM WITH SUDDEN ACCELERATION A COUPLE TIMES WHEN DRIVING AT SLOW SPEED. *TR

THERE ARE SEVERAL PROBLEMS I'VE EXPERIENCED WITH THE 2010 TOYOTA PRIUS PURCHASED NEW 10 DECEMBER 2009. 1. WHEN USING CRUISE CONTROL: ~ THERE'S REGULARLY WHAT FEELS LIKE AN ENGINE SURGE WHEN THE FOOT BRAKE IS APPLIED TO TURN OFF CRUISE CONTROL. THIS HAPPENS REGULARLY, INCLUDING ON SMOOTH, LEVEL, DRY ROADWAYS AND FREEWAYS AND AT SPEED SETTINGS FROM 45 TO 60 MPH. BECAUSE OF CONCERN ABOUT THIS I NOW MANUALLY TURN OFF CRUISE CONTROL. THREE DAYS AGO THE CAR WAS TEST DRIVEN BY A TOYOTA DEALERSHIP SERVICE DEPARTMENT EMPLOYEE, WHO REPORTED USING CRUISE CONTROL 6 TIMES AND TURNING CRUISE CONTROL OFF BY APPLYING THE FOOT BRAKE; THE REPORT WAS 'CRUISE CONTROL SHUT OFF IMMEDIATELY WHEN ENOUGH PRESSURE APPLIED [EMPHASIS ADDED] TO PEDAL.' ~ ON SATURDAY, FEBRUARY 27, 2010 AFTER THE CAR HAD BEEN SET AT 60 IN CRUISE CONTROL FOR SOME TIME THERE WAS A STRONG ODOR (LIKE A CAR BEING DRIVEN WITH THE "HAND" BRAKE ON, BUT MY CAR'S WASN'T ENGAGED) WHILE ON A DRY FREEWAY DOWNGRADE (GRADUAL, NOT STEEP). I TURNED OFF THE CRUISE CONTROL, CONTINUED AT THE SAME SPEED AND THE ODOR STOPPED. THIS WAS THE FIRST SUCH OCCURRENCE. I'VE USED CRUISE CONTROL REGULARLY BECAUSE OF USUALLY DRIVING ON FREEWAYS 6 DAYS/WEEK. THE TOYOTA SERVICE DEPARTMENT'S TEST DRIVE THREE DAYS AGO REPORTED 'NOT EVIDENT.' 2. SHIFTING FROM PARK TO DRIVE SEVERAL TIMES THIS SHIFTING WAS SUCCESSFUL ONLY AFTER MULTIPLE TRIES. ON ONE RECENT OCCASION AFTER SEVERAL TRIES AND ALSO TURNING THE CAR OFF, ON AGAIN, AND THEN UNSUCCESSFULLY RETRYING, I RESORTED TO USING THE SAFETY CONNECT SOS BUTTON. THERE WERE NO DOORS AJAR AND NO INDICATION OF THE CAUSE. WHILE TALKING WITH THE PERSON WHO RESPONDED I PERIODICALLY CONTINUED TO TRY SHIFTING FROM PARK TO DRIVE; AFTER SEVERAL ATTEMPTS THE CAR RESPONDED. *TR

ON FRIDAY 2/26 AT ~ 1:15PM, I WAS DRIVING MY 2010 PRIUS. IT WAS RAINING HARD OUTSIDE. AS I PUT ON BRAKES, THE CAR SEEMED TO ACCELERATE / DID NOT BRAKE AND DROVE INTO A PARKING LOT CURB. DAMAGE WAS DONE TO THE FRONT END OF THE CAR. THERE HAVE BEEN MULTIPLE OCCASIONS DURING WHICH MY HUSBAND AND I HAVE SEPARATELY NOTICED THIS SAME TYPE OF ACCELERATION / FAILURE TO BRAKE - PARTICULARLY WHEN DRIVING IN THE RAIN, DOWN A HILL, OR OVER AN UNEVEN SURFACE (LIKE A POTHOLE). NONE OF THESE OTHER OCCASIONS HAVE RESULTED IN ANY INJURY OR DAMAGE. FOLLOWING THE 2/26/2010 INCIDENT, I CONTACTED TOYOTA THAT SAME DAY. I WAS TOLD THAT A CUSTOMER RELATIONS MANAGER WOULD CALL ME BACK BY TUESDAY 3/2. DID NOT HEAR BACK. ON WEDNESDAY 3/3 I CALLED TO FOLLOW UP. AFTER BEING ON HOLD FOR 1 HOUR, I GAVE UP. SENT AN E-MAIL TO CUSTOMER SERVICE ADVISING OF THE SITUATION. STILL DID NOT HEAR BACK. ON SATURDAY 3/6 I CALLED AGAIN. WAS AGAIN ON HOLD X 1 HOUR AND TOLD CUSTOMER SERVICE REPRESENTATIVE OF WHAT HAPPENED - THEY APOLOGIZED AND SAID THEY DID NOT HAVE MY CONTACT INFORMATION. WAS TOLD I WOULD GET A CALL BACK BY 3/9. DID FINALLY SPEAK WITH AN AGENT ON 3/8 WHO NOW TELLS ME THAT I WILL GET A CALL WITHIN 10 DAYS. AT THAT TIME, I WILL BE OFFERED AN INSPECTION APPOINTMENT WITHIN THE FOLLOWING 30 DAYS. AND, WITHIN 30 DAYS AFTER THE APPOINTMENT I WILL RECEIVE WRITTEN NOTIFICATION OF THE OUTCOME OF THE INSPECTION. I FEEL UNSAFE DRIVING MY CAR. I WOULD HOPE FOR A FASTER RESOLUTION TO THIS SITUATION. I WOULD LIKE FOR THE ABS FIX FOR WHICH THE 2010 PRIUS IS BEING RECALLED TO BE COMPLETED AS SOON AS POSSIBLE. AND, I WOULD LIKE FOR THE DAMAGE TO MY CAR TO BE REPAIRED. *TR

I HAVE OWNED 4 TOYOTA PRIUS HYBRID VEHICLES (2005, 2007, 2008, 2010). I EXPERIENCED A SLIGHT FEELING OF ACCELERATION SOMETIMES WHEN DEPRESSING THE GAS PEDAL IN THE 07 AND 08 MODELS. I ALSO FELT A SLIGHT SURGE SOMETIMES WHEN BRAKING. WHEN I ASKED THE TOYOTA MECHANIC ABOUT THIS I WAS TOLD THAT STORED ENERGY FROM THE HYBRID SYSTEM WAS BEING EXPELLED. I NEVER THOUGHT IT MIGHT BE A SAFETY ISSUE BECAUSE OF WHAT HE SAID. NOW I DRIVE THE 2010 PRIUS, HAD THE BRAKE RECALL DONE LAST WEEK AND A COUPLE DAYS LATER, WHEN DRIVING OVER 3 SLIGHT BUMPS WHEN ENTERING A PARKING LOT, I FELT THAT SAME SLIGHT ACCELERATION. PLEASE CONTINUE DEMANDING TOYOTA FIX THIS DANGEROUS PROBLEM. PLEASE TALK TO THE US CONGRESS ABOUT INVESTIGATING THESE CARS BEFORE THERE ARE MORE ACCIDENTS. I THINK THE 2010 PRIUS ALSO HAS ISSUES WITH ACCELERATION AS WELL AS BRAKING BECAUSE I HAVE EXPERIENCED WHAT I DESCRIBED IN THE 07, 08, 10 MODELS. *TR

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). I LEFT A MESSAGE ON YOUR VOICE MAIL. I HAVE A 2010 PRIUS. I CALLED MY DEALERSHIP THIS AM WITH CONCERN ABOUT THE INCIDENT LAST NIGHT WITH THE GAS PEDAL. THE GENTLEMAN THAT SPOKE TO ME WAS VERY ARROGANT STATING "I DON'T KNOW WHAT EVERYONE IS SO WORRIED ABOUT, ALL HE HAD TO DO WAS PUT IT IN NEUTRAL". I ASKED HIM TO STAY ON THE PHONE WITH ME WHILE I DID A TEST RUN IN MY CAR. I GOT IN THE CAR (WITH HIM ON THE PHONE) STARTED DRIVING AND PUT MY FOOT ON THE BRAKE AND PUSHED THE JOY STICK TO NEUTRAL, NOTHING HAPPENED, THE CAR REMAINED IN DRIVE. I PROCEEDED TO DO THIS 13 TIMES WITH THE DEALERSHIP ON THE PHONE, IT ONLY ENGAGED IN NEUTRAL 2 TIMES OUT OF THE 13. I WAS GETTING UPSET AND VOICING MY CONCERN. I ASKED IF I COULD BRING IT IN AND HAVE IT CHECKED OUT. THE DEALERSHIP SAID TO ME "SURE YOU CAN BRING IT IN BUT I DON'T KNOW WHAT I CAN DO ABOUT IT". I WAS FURIOUS, I CALLED THE LOCAL CHANNEL 3 AND THEY CAME OUT AND DID A STORY ON IT. WE DROVE THE CAR AROUND AND I PUT IT IN NEUTRAL PROBABLY AT LEAST 30-50 TIMES AND IT DID NOT ENGAGE 90% OF THE TIME. I TRIED CALLING TOYOTA HEADQUARTERS AND THEY ARE NOT TAKING ANY CALLS AT THIS TIME, THIS WAS A QUOTE AND ANIMATED, YOU CANNOT TALK TO A REAL PERSON. I DON'T WANT THE CAR, I AM AFRAID TO DRIVE IT.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS DRIVING APPROXIMATELY 20 MPH WITH THE BRAKE ENGAGED WHEN THE VEHICLE ACCELERATED. THE CONTACT CRASHED INTO THE REAR END OF A NISSAN. THE WEATHER WAS NOT A FACTOR. THE CONTACT OBSERVED SMOKE COMING FROM THE VEHICLE. THE REAR SUSPENSION WAS DAMAGED AFTER THE CRASH OCCURRED. THE INSURANCE COMPANY AUTHORIZED THE VEHICLE TO BE TOWED TO AN IMPOUND LOT. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE AND CURRENT MILEAGES WERE 36,000.

2010 TOYOTA PRIUS - I WAS DRIVING MY 2010 TOYOTA PRIUS FOR A SHORT PERIOD AS A COMPANY CAR. I NOTICED THAT WHEN THE BATTERY GOT LOW WHILE IN PARK THE ENGINE WOULD KICK IN TO RECHARGE THE BATTERY. THE ENGINE WOULD CAUSE THE CAR TO SLIGHTLY JERK FORWARD OR BACK WHICH WOULD BE EXPECTED BY THE FORCE OF THE ENGINE THRUST. WHAT WAS STRANGE IS THAT WHEN I WAS CROSSING THE STREET AFTER COMING OUT OF AN OIL CHANGE, MY FOOT WAS ON THE BRAKE WAITING FOR TRAFFIC TO CLEAR ONLY TO HAVE THE ENGINE KICK IN AND SLIGHTLY JERK THE CAR FORWARD. IT SURPRISED ME! LIKE I SAID MY FOOT WAS ON THE BRAKE AND KEPT THE CAR FROM MOVING. I VISITED THE TOYOTA DEALERSHIP TO DISCUSS AND EMAILED TOYOTA TO MAKE THEM AWARE OF IT. AFTER HEARING MORE NEWS ABOUT TOYOTA I FELT I NEEDED TO SHARE THIS INFORMATION. I NO LONGER HAVE THE CAR BECAUSE I DID NOT FEEL SAFE, WITH ALL OF THE PROBLEMS WITH TOYOTA, SO I TURNED IT BACK IN TO MY FLEET WHO MANAGES THE COMPANY CARS. I HAVE ALSO NOTICED A WINDING SOUND IN THE STEERING WHEEL WHEN IT IS TURNING. I CANNOT RECALL THE EXACT DATE OF THE INCIDENT SO I HAVE MENTIONED FEB 19 2010 AS THE APPROXIMATE DATE. IF YOU NEED AN EXACT DATE PLEASE CONTACT ME SINCE I CAN GO TO THE SITE WHERE I GOT MY OIL CHANGE AND LOOK UP MY RECORDS TO PROVIDE AN EXACT DATE. *TR

TOYOTA VEHICLES IN ALL OF THE INFORMATION I HAVE READ, TOYOTA NOR THE DEPARTMENT OF TRANSPORTATION HAS INFORMED DRIVERS TO SHIFT THE VEHICLE TO NEUTRAL WHEN IT ACCELERATING BY ITSELF. BY SHIFTING THE TRANSMISSION TO NEUTRAL IT SHOULD ALLOW THE DRIVER TO BRING THE VEHICLE TO A SAFE STOP. *TR

WHEN BACKING UP, THE CAR WILL, ON OCCASION, AUTOMATICALLY ACCELERATE EXCESSIVELY. THIS CAUSES THE DRIVER TO NEED TO STEP AGGRESSIVELY ON THE BRAKE IN ORDER TO CONTROL THE CAR. THIS CYCLE OF "RACE AND BRAKE" CONTINUES UNTIL OUR NEED TO REVERSE IS COMPLETE. ONCE WE ARE IN DRIVE THERE IS NO FURTHER PROBLEM. THIS HAS OCCURRED ABOUT SIX TIMES SINCE WE PURCHASED THE CAR IN LATE JULY. IT HAS MOST OFTEN OCCURRED WHEN IT IS THE INITIAL DRIVE OF THE DAY, BUT THE MOST RECENT TIME THE CAR HAD ALREADY BEEN DRIVEN 100 MILES AND HAD BEEN IDLING FOR SEVERAL MINUTES. WE CONTACTED THE DEALERSHIP FROM WHICH WE BOUGHT THE CAR. THEY HAVE NOT HEARD OF THE ISSUE. WE ALSO TOOK IT INTO OUR LOCAL DEALERSHIP. THEY WERE, OF COURSE, NOT ABLE TO REPLICATE THE PROBLEM. NO RESOLUTION OR CORRECTION HAS OCCURRED. *TR

2010 TOYOTA PRIUS CRUISE CONTROL CAUSED UNINTENDED ACCELERATION WHEN RE-ENGAGED. AFTER DISENGAGING CRUISE CONTROL SET TO 65 AND COASTING AT 50 FOR A WHILE WHEN THE CRUISE CONTROL WAS RE-ENGAGED THE VEHICLE RESUMED IN EXCESS OF 70 MPH BEFORE I DISABLED CRUISE CONTROL. DATE OF INCIDENT IS APPROXIMATE. I DIDN'T THINK MUCH OF THE FAILURE AT THE TIME OTHER THAN THAT THE CRUISE CONTROL WAS BEHAVING ODDLY (I HAVE AVOIDED CRUISE CONTROL ON THIS CAR SINCE). IN LIGHT OF THE CURRENT INVESTIGATION I THOUGHT I WOULD SUBMIT A REPORT. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE VEHICLE ACCELERATED ON ITS OWN WHILE DRIVING 30 MPH, WHEN THE CONTACT ATTEMPTED TO STOP AT AN INTERSECTION. THE FAILURE OCCURRED SIX TIMES. THE DRIVER STATED THAT WHEN THE FAILURE OCCURRED THEY WERE UNABLE TO STOP THE VEHICLE. THE TOYOTA DEALER STATED THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. THE FAILURE HAS OCCURRED FOR OVER 9 MONTHS. THE CONTACT HAS NOT RECEIVED A RECALL NOTICE FROM THE DEALER BUT SHE IS AWARE OF AN EXISTING RECALL. THE FAILURE MILEAGE WAS 2,500. THE CURRENT MILEAGE WAS 5,500.

WE BOUGHT A 2010 TOYOTA PRIUS II IN 7/2009. WE HAVE ON MULTIPLE OCCASIONS EXPERIENCED A BRIEF ACCELERATION OF THE CAR WHEN OUR FOOT IS APPLYING THE BRAKE PEDAL TO TRY AND SLOW DOWN. MOST OF THESE OCCASIONS HAVE HAPPENED WHEN GOING OVER BUMPS AND OFTEN WHEN TURNING A CORNER. WE DID HAVE THE SOFTWARE UPGRADE THAT WAS RECOMMENDED BY THE RECALL JUST 2 WEEKS AGO. STILL, MY WIFE EXPERIENCED THE SAME PROBLEM AGAIN WHEN COMING HOME IN THE CAR A FEW DAYS AGO. IT HAS HAPPENED IN TOTAL ABOUT 5 TIMES SINCE WE BOUGHT THE CAR IN 7/09 AND HAVE DRIVEN ABOUT 10,000 MILES. ON ONE OCCASION LAST YEAR I ALMOST LOST CONTROL OF THE CAR GOING AROUND A CURVE BECAUSE OF THE ACCELERATION. I DON'T THINK THIS IS SIMPLY A BRAKE ISSUE, THE CAR ACTUALLY SEEMS TO ACCELERATE BRIEFLY. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE DRIVER STATED THAT SHE RECENTLY HAD A RECALL REPAIR PERFORMED ON HER VEHICLE FOR THE ACCELERATION; HOWEVER, SHE CONTINUED TO EXPERIENCE THE IDENTICAL FAILURE. WHEN SHE DROVE OVER A BUMP IN THE ROAD, THE VEHICLE ACCELERATED ON IT'S OWN. SHE CALLED THE SERVICE MANAGER AND SHE IS WAITING FOR A RETURN CALL FROM HIM. THE FAILURE MILEAGE WAS 500. THE CURRENT MILEAGE WAS 8,000.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT WAS STOPPED THE VEHICLE AND THEN NOTICED THAT THE ENGINE WOULD SUDDENLY SURGE WITHOUT WARNING UNTIL THE VEHICLE WAS TURNED OFF. THE VEHICLE HAS NOT BEEN DIAGNOSED BY THE DEALERSHIP AND THERE WERE NO PRIOR WARNINGS. THE CURRENT AND FAILURE MILEAGES WERE 4700.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING IN REVERSE OUT OF THE GARAGE HE EXPERIENCED AN UNINTENDED ACCELERATION AT LEAST THREE TIMES WITHIN A MONTH. ALSO WHEN HE WAS DRIVING AT 5 MPH AND COMING TO A STOP, THE VEHICLE LUNGED FORWARD AND AS HE JAMMED HIS FOOT HARDER ON THE BRAKES, THE VEHICLE KEPT GOING . THE VEHICLE WAS TAKEN TO THE DEALER ON TWO OCCASIONS; HOWEVER, DURING A TEST DRIVE THEY WERE UNABLE TO DUPLICATE, DIAGNOSE OR REPAIR THE FAILURE. THE TOYOTA MANUFACTURER HAS NOT BEEN CALLED. THE FAILURE MILEAGE WAS 1,700.

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS HYBRID. HE STATED THAT WHEN THE GASOLINE ENGINE WAS ENGAGED IN ANY GEAR, INCLUDING THE PARK POSITION, THE VEHICLE WOULD SURGE. HE ALSO STATED THAT UPON TURNING THE GASOLINE ENGINE OFF, THE VEHICLE WOULD MOMENTARILY ROLL BACKWARDS. THIS WOULD OFTEN OCCUR WHILE ANY ELECTRICAL COMPONENT OF THE VEHICLE WAS UTILIZED, TO INCLUDE THE HEATER, DEFROST AND RADIO. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY COULD NOT DUPLICATE THE FAILURE. THE DEALER STATED THAT THE VEHICLE WAS OPERATING AS IT WAS DESIGNED. THERE WERE NO REPAIRS MADE TO THE VEHICLE TO DATE. THE FAILURE MILEAGE WAS 200 AND THE CURRENT MILEAGE WAS 1,398.

MY 2010 PRIUS HYBRID ACCELERATES FROM ELECTRIC TO FUEL MODE ON ITS OWN. I HAVE TAKEN IT TO TOYOTA DEALERSHIP 2 TIMES FOR PROBLEM. TOYOTA SERVICEMEN STATES IT WILL OCCASIONALLY DO THAT DEPENDING ON THE MODE THE VEHICLE IS IN. I FIND IT TO BE VERY DANGEROUS AS I DO NOT HAVE CONTROL WHEN IT WILL HAPPENS. SERVICEMEN ALSO SAID THAT IS WHY THERE IS AN ALARM BEEPING TO LET DRIVER KNOW IT IS BACKING UP. THAT DOES NOT MAKE SENSE THE ALRM IS NOT GOING TO CONTROL THE MODE THE VEHICLE IS IN. IT IS A SAFETY ISSUE SEVERAL TIMES I HAVE ALMOST HIT OTHER VEHICLES OR PEDESTRIANS WHEN BACKING UP. I NOW TRY NOT TO USE REVERSE TO AVOID A POSSIBLE ACCIDENT. PLEASE LET ME KNOW IF OTHER VEHICLES HAVE SIMILAR PROBLEMS. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE DRIVER STATED THAT SHE WAS TRAVELING 35 MPH WHEN SHE SWITCHED LANES. WHEN SHE APPLIED THE BRAKES AND THE VEHICLE STARTED TO STOP BUT THEN IT LUNGED FORWARD AND ACCELERATED ON IT'S OWN WHILE HER FOOT WAS ON THE BRAKE PEDAL. THE DRIVER STATED THAT THE VEHICLE THEN CAME TO A STOP AFTER HER FOOT REMAINED ON THE BRAKE PEDAL. THE DRIVER DID NOTIFY THE DEALER OF THE FAILURE. THE VIN WAS UNKNOWN. THE FAILURE MILEAGE AND CURRENT MILEAGES WERE 10,000.

INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) FEBRUARY 15, 2010 AT 3:29 PM I SPOKE TO [XXX] AT TOYOTA 1-800-331-4331 ABOUT PROBLEMS I'VE EXPERIENCED WITH MY 2010 PRIUS. I TOLD HER ABOUT THE CRUISE CONTROL DANGER, WHERE THE CAR HAD BEEN GOING ALONG NICELY ON CRUISE, BUT SUDDENLY RAPIDLY ACCELERATED WHEN, ON AUGUST 11, 2009, I WAS ON THE TRIP BETWEEN NEW JERSEY AND ILLINOIS COMING THROUGH THE TENNESSEE/KENTUCKY AREA. I HAD BEEN TRAVELING AT ABOUT 65MPH ON CRUISE AND IT RAPIDLY ACCELERATED TO OVER 80MPH AND I PANICKED WHILE TRYING TO GET IT TO SLOW DOWN. I TRIED SLOWING IT DOWN USING THE CRUISE BUTTON, THEN DEPRESSED THE CRUISE OFF BUTTON. DIDN'T WORK. IT DID NOT RESPOND IMMEDIATELY TO THE BRAKE UNTIL I BRAKED REALLY HARD. THEREFORE, MY DRIVING IT WAS SEVERELY LIMITED TO DRIVING AT VERY LOW SPEEDS IN TOWN. OTHER UNINTENDED ACCELERATION HAS OCCURRED EVEN WHEN NOT USING THE CRUISE. THE CAR BOLTED FORWARD NUMEROUS TIMES ON A BUMPY SECTION OF ROAD ON MY ROUTE HOME FROM WORK; IT HAPPENED OFTEN ENOUGH THERE THAT I COMPENSATED BY TAKING A DIFFERENT ROUTE. EFFORTS TO STOP THE FORWARD LUNGE INCLUDED BRAKING WITH NO RESPONSE, USING THE KNOB TO SHIFT TO A DIFFERENT SETTING, AND SCRAMBLING TO FIND THE [XXX] BUTTON TO PRESS PARK. SOMETHING FINALLY STOPPED IT, BUT I DON'T KNOW WHAT. THE NEXT SCARE OCCURRED AFTER IT SNOWED. I DROVE SLOWLY ON THE PLOWED ROAD, BUT WHEN THE CAR ENCOUNTERED SNOWY LUMPS IT RAPIDLY ACCELERATED LUNGING FORWARD AGAIN. MY ATTEMPTS TO STOP CAUSED ME TO SKID DANGEROUSLY INTO ONCOMING TRAFFIC LANE. I PARKED THE CAR IN THE GARAGE AND HAVE NOT DRIVEN IT AGAIN IN WELL OVER A MONTH DUE TO THE DANGER. IN FEBRUARY, MY CO-WORKER[XXX] URGED ME NOT TO DRIVE THE CAR BECAUSE SHE HAD HEARD ABOUT A RECALL AND WAS AFRAID FOR ME, BUT I HAD ALREADY PARKED IT BY THEN ' KNOWING SOMETHING WAS WRONG WITH IT. IT HAS NOT BEEN DRIVEN SINCE PRIOR TO MY LEARNING THAT OTHERS HAVE HAD SIMILAR EXPERIENCES ' SOME HAVE DIED OR BEEN INJURED AS A RESULT.

2010 TOYOTA PRIUS; WHEN SHIFTING INTO REVERSE IS SPORADICALLY DIFFICULT TO CONTROL ACCELERATION. LIFTING MY FOOT OFF THE BRAKE A TINY AMOUNT CAUSES THE CAR TO FEEL LIKE IT IS "SURGING" BACKWARD. THE CAR IS CONTROLLABLE, BUT IT IS A VERY DIFFERENT EXPERIENCE FROM BEING IN REVERSE MOST OF THE TIME. SHIFTING TO PARK AND BACK TO REVERSE SEEMS TO MAKE IT GO AWAY. THIS HAS HAPPENED TO ME 4 TIMES SINCE I BOUGHT THE CAR IN AUGUST 2009. *TR

OUR 2010 PRIUS WAS EXPERIENCING SURGING OVER BUMPS, WE HAD IT RE-PROGRAMMED LAST WEEK AND TODAY WE EXPERIENCED THE SURGE AGAIN WHEN WE WENT OVER A BUMP, JUST LIKE BEFORE. *TR

IN MY 2010 PRIUS, THE VEHICLE RANDOMLY ACCELERATES WHEN THE CRUISE CONTROL IS DISENGAGED. THIS HAPPENS EVERY 10TH OR 15TH TIME OF DISENGAGEMENT. WHEN THE BRAKES ARE APPLIED HARDER THE VEHICLE SLOWS PROPERLY. THE UNEXPECTED ACCELERATION IS VERY DANGEROUS IN TRAFFIC. THE VEHICLE HAS BEEN CHECKED BY THE DEALER AND I WAS TOLD THAT NOTHING IS WRONG. I CALLED FOR A SECOND TIME AND WAS TOLD THE PROBLEM IS NOT ON THE RECALL LIST. I WILL TAKE IT IN ANYWAY NEXT WEEK. *TR

WHEN I AM DRIVING MY TOYOTA PRIUS 2010 AND THE VEHICLE GOES OVER A BUMP OR HOLE IN THE ROAD THE VEHICLE "JUMPS" ESPECIALLY IS I AM BRAKING TO SLOW THE VEHICLE DOWN. *TR

CRASH DUE TO BRAKE FAILURE, SUDDEN UNINTENDED,SUDDEN UNCONTROLLED DANGEROUS ACCELERATION, SURGING FORWARD MOMENTARY LOSS OF BRAKING CAPABILITY WHILE TRAVELING EXTREMELY LOW SPEED UNDER 5 MPH ON AN UNEVEN BUMPY COUNTRY ROAD SURFACE, POTHOLE, OR BUMP, LURCHED FORWARD SKIDDED SIDE WAYS INTO TREE. FREQUENTLY OCCURS. MAJOR COLLISION DAMAGE, IN REPAIR SHOP 1 MONTH. *TR UPDATED 04/27/10.*LJ UPDATED 08/11/10

I HAVE A 2010 PRIUS. EVERYONE IN THE MEDIA IS TALKING ABOUT BRAKE ISSUES BUT THE REAL PROBLEM IS THAT THE CAR ACCELERATES AFTER IT HITS BUMPS IN THE ROAD. IT FEELS LIKE AN ELECTRONIC PROBLEM. THE BRAKES AREN'T THE ISSUE.*TR

USING CRUISE CONTROL FEATURE,WHEN I HIT THE BRAKE FOR SPLIT SECOND THE CAR SPEEDS UP BEFORE DISENGAGING CRUISE CONTROL THIS HAPPEN ALL THE TIME NOT ON JUST THE DATE BELOW. *TR

THIS PROBLEM HAS EXISTED SINCE THE VEHICLE WAS PURCHASED. CRUISE CONTROL EITHER DOES NOT FUNCTION AT ALL OR FAILS TO FUNCTION CORRECTLY. SOMETIMES THE CRUISE CONTROL WILL NOT ENGAGE. SOMETIMES THE CRUISE CONTROL WILL ENGAGE PROPERLY, BUT AFTER APPLYING THE BRAKES (AND DISENGAGING THE CRUISE CONTROL) THE CRUISE CONTROL CANNOT BE REENGAGED. TWO OPERATIONS WILL CAUSE THE CRUISE CONTROL TO BEGIN FUNCTIONING PROPERLY AGAIN: 1) TURN THE VEHICLE OFF; 2) PUT THE SHIFT LEVER INTO THE NEUTRAL POSITION, THEN BACK INTO DRIVE. RETURNED VEHICLE TO DEALER THREE TIMES FOR REPAIR. THEY DID NOT FIX THE MALFUNCTION DURING ANY OF THE THREE REPAIR VISITS. THEIR FINAL RESPONSE WAS TO CLAIM THAT THE VEHICLE WAS "FUNCTIONING AS DESIGNED". *TR

I HAVE A 2010 PRIUS. OCCASIONALLY WHEN I GO OVER A BUMP (POTHOLE, TRAIN TRACK, ROUGH ROAD) MY CAR FEELS LIKE IT JOLTS FORWARD FOR A FEW SECONDS. THIS HAPPENS WHEN I AM NOT HITTING THE BRAKES SO I DON'T THINK IT IS COVERED BY THE ANTI-LOCK BRAKING RECALL. IT IS DIFFICULT TO REPLICATE THIS AND I HAVEN'T REPORTED IT TO THE DEALER BECAUSE OF THIS, BUT IT HAPPENS ABOUT 1-2/WEEK. IT COULD BE A PROBLEM IN A TRAFFIC SITUATION WHERE CARS ARE FOLLOWING CLOSELY. *TR

I OWN A TOYOTA 2010 PRIUS. I COMPLAINED TO THE DEALERSHIP WHERE I BOUGHT MY CAR IN JULY AT MY FIRST SERVICE/OIL CHANGE ABOUT A SUDDEN SURGE IN SPEED WHILE DRIVING OVER BUMPY SURFACES. I PRESENTED THEM WITH INTERNET INFORMATION I HAD COPIED FROM CONSUMERS HAVING THE SAME PROBLEM BUT THEY WOULD NOT TAKE THEM FROM ME. THEY SERVICED THE CAR, DROVE IT AND RETURNED IT TO ME SAYING THEY FOUND NO PROBLEMS AND THAT I WAS THE ONLY PERSON WHO HAD EVER COMPLAINED ABOUT IT. THEY SAID THEY KNEW OF NO OTHER SIMILAR COMPLAINTS. I ASKED THEM TO PUT ON MY BILL THE FACT THAT THIS WAS HAPPENING TO MY CAR SO THAT IT WOULD BE DOCUMENTED FOR THE FUTURE. THEY DID NOT SEEM AT ALL CONCERNED AT THE TIME. IT REMAINS AN ONGOING PROBLEM WHEN I DRIVE. *TR

TO THE NHTSA: I AM AN OWNER OF A 2010 TOYOTA PRIUS THAT I PURCHASED IN JUNE 2009. SINCE OWNING THE VEHICLE, I HAVE HAD ABOUT A HALF-DOZEN TO A DOZEN OCCURRENCES OF THE SAME PROBLEM. AT LOW SPEEDS, WHEN THE REAR WHEEL HITS A BUMP, FOR A SPLIT-SECOND THE CAR FEELS LIKE THERE IS A BURST OF ACCELERATION AND IS OUT OF CONTROL. THIS LASTS ONLY A SPLIT-SECOND. I SAW ANOTHER CONSUMER IN A NEWS ARTICLE ABOUT THE PRIUS BRAKE ISSUE DESCRIBE IT THE EXACT SAME WAY. I ACTUALLY MENTIONED THIS TO MY DEALER (BERNARDI TOYOTA, FRAMINGHAM, MA) WHEN I BROUGHT THE CAR IN FOR THE 5,000 MILE SERVICE A MONTH OR SO AGO. THE SERVICE DEPT TOLD ME THAT THE BEHAVIOR IS NORMAL FOR THE HYBRID VEHICLES, AND KNOWN BY TOYOTA -- NO FIX OR ADJUSTMENT RECOMMENDED. THIS SEEMED LIKE AN ODD RESPONSE, BUT BECAUSE THEY TOLD ME THERE WAS NO SAFETY ISSUE, I LEFT IT AT THAT. I AM PROVIDING MY EXPERIENCE TO AID THE NHTSA APPLY PRESSURE ON TOYOTA TO FIX THIS PROBLEM IN THE PRIUS. *TR

2010 TOYOTA PRIUS, PURCHASED NOV. 2009. USING CRUISE CONTROL, THE CAR ACCELERATED QUICKLY ON IT'S OWN WHEN I ATTEMPTED TO CHANGE SPEED BY USING THE CRUISE CONTROL LEVER ON THE STEERING WHEEL. HAPPENED TWICE, THEN I STOPPED EXPERIMENTING FOR REASONS OF SAFETY. THE PROBLEM IS IDENTICAL TO THE ONE DESCRIBED BY STEVE WOSNIAK IN PUBLIC TWO WEEKS AGO--ONE THAT GOT A LOT OF PRESS. ACCELERATION STOPPED WHEN BRAKE PEDAL WAS TAPPED OR CRUISE CONTROL WAS TURNED OFF. *TR

1. I WAS DRIVING IN SAN FRANCISCO, CA ON CITY ROADS. IN BOTH EVENTS, I WAS BRAKING TO MINIMIZE THE IMPACT OF DRIVING OVER POTHOLES OR UNEVEN PAVEMENT (HOLES THAT WERE RECENTLY FILLED WITH ASPHALT) SEEN AHEAD. 2. WHEN THE BRAKES WERE APPLIED, THERE WAS A BRIEF, MOMENTARY SURGE IN POWER FOLLOWED BY NORMAL BRAKING. ON ONE OCCASION, A PASSENGER RIDING IN THE FRONT PASSENGER SEAT ALSO NOTICED THE SURGE AND COMMENTED ON IT. 3. NO CORRECTIVE ACTION HAS BEEN TAKEN SO FAR. AWAITING NEWS ON A POSSIBLE RECALL AND INSTRUCTIONS FROM CAR MARKER ON CORRECTIVE ACTIONS TO BE TAKEN. *TW

2010 PRIUS, LESS THAN 5000 MILES. ON THE I-5 (CA) GOING TO SAN FRANCISCO ON 12-24-09. ON A SLIGHT/MODERATE DOWNGRADE WITH CRUISE SET AT 70 MPH, THE CAR WAS BRAKING HARD AND WAS OVER 100 MPH BEFORE I REALIZED WHAT THE NOISE WAS - AND IMMEDIATELY TOOK IT OUT OF CRUISE AND BRAKED. IT CAME UNDER CONTROL. ON OR ABOUT 12-31-09 I WAS UNABLE TO ENGAGE CRUISE ON THE FREEWAY BUT THE FOLLOWING DAY IT ENGAGED NORMALLY. *TW

SOON AFTER I GOT MY 2010 PRIUS IN AUGUST, I EXPERIENCED A BRAKING PROBLEM. THIS HAS HAPPENED ABOUT 8 MORE TIMES SO FAR. WHILE BRAKING AS I SLOWLY APPROACH A STOP SIGN OR LIGHT, IF I SIMULTANEOUSLY GO OVER A BUMP OR BREAK IN THE ROAD, THE CAR WILL LURCH FORWARD A COUPLE OF YARDS REQUIRING ME TO PUSH HARDER ON THE BRAKE WHICH THEN STOPS THE CAR. THIS PROBLEM HAS ALSO HAPPENED 2 TIMES IN THE LAST WEEK WHILE DRIVING SLOWLY AND THEN BRAKING WHEN I ENCOUNTER ICE ON THE ROAD. LUCKILY, NO CARS HAVE BEEN DIRECTLY IN FRONT OF ME WHEN THIS HAS HAPPENED. I HAVE NOT REPORTED THIS TO TOYOTA BECAUSE I HAVE NOT YET SERVICED MY CAR. *TW

PRIUS PURCHASED NOV 2009: AT LEAST INCIDENTS OF CAR LURCHING FORWARD SIGNIFICANTLY AND MOMENTARY SENSE OF LOSS OF CONTROL WHEN BRAKING ON UNEVEN SURFACE. OCCURED IN DEC 09,JAN 10, AND FEB 10. HAD A PEDESTRIAN BEEN CROSSING ILLEGALLY, THE PERSON COULD'VE BEEN HIT BEC I COULD NOT PREVENT OR CONTROL THAT LURCHING. THIS IS A DANGEROUS SITUATION. I FEEL I CANNOT DRIVE MY CAR SAFELY. I NEED MY CAR FOR WORK. I PHONED MY TOYOTA DEALER WHO SAID TO BRING IT IN FOR EVALUATION,BUT THEY SOUND TENTATIVE. I WANT A SOLUTION AND DON'T WANT TO BE MAKING NUMEROUS TRIPS FROM MY RURAL TOWN TO THE CITY DEALER FOR GUESSES. *CN

SUDDEN ACCELERATION WHEN PASSING OVER ROUGH SPOTS(HAS HAPPENED WITH MANHOLE COVER). BRAKING STOPS THE ACCELERATION. *CN

MY 2010 PRIUS HAS SPED UP AT LEAST THREE TIMES WHEN I EITHER DRIVE THROUGH A POTHOLE OR CROSS RAILROAD TRACKS, FORCING ME TO HIT THE BRAKES HARD. THE BRAKES WORKED AS THEY SHOULD AND NO ACCIDENT RESULTED. *TR

THE CAR, A 2010 PRIUS, ACCELERATES FORWARD WHEN GOING OVER A BUMP IN THE ROAD OR A POTHOLE, AS THE BRAKE IS APPLIED. THE PROBLEM OCCURS AT AN UNPREDICTABLE FREQUENCY. THE CONSEQUENCES ARE THAT I LOSE CONTROL OF THE CAR'S SPEED. I HAVE REPORTED THIS PROBLEM TO MY DEALERSHIP SEVERAL TIMES SINCE PURCHASING THE PRIUS AND THEY HAVE FOUND NO PROBLEM, STATING THERE IS NOTHING TO FIX. I HAVE BEEN VERY CONCERNED ABOUT THE PROBLEM, EVEN BEFORE THE RECENT EVENTS IN THE NEWS ABOUT TOYOTA. HAD I KNOWN ABOUT THIS SITE, I WOULD HAVE REGISTERED THE COMPLAINT EARLIER. *TR

I HAVE NOTICED ISSUE WITH BRAKING. I REMEMBER IT HAD RAINED THE PREVIOUS NIGHT AND THE MORNING IT WAS FREEZING. I WAS DRIVING ON RT. 76 TO DROP MY SON OFF TO HIS WORK. ON SMALL STRETCH OF RT. 76 HAS THE 'CEMENT PATCH' - THOSE YOU TYPICALLY SEE ON A OVER PASS. FEARING ICING, I HIT THE BRAKE ONLY TO FEEL IT NOT RESPONDING. IN FACT, I FELT THE CAR SPEEDING UP. THE PATCH WAS JUST ABOUT 10-15 FT WIDE; THE MOMENT WE WERE OVER IT, I FELT THE BRAKES RESPOND. *TR

WHEN THE ROAD SURFACE IS SLIPPERY AND/OR UNEVEN (I.E, POTHOLE IS BEGINNING TO FORM), MY 2010 TOYOTA PRIUS HAS "SURGED" OR ACCELERATED SUDDENLY AT LOW SPEEDS UNDER 30 MPH, FOR NO APPARENT REASON OTHER THAN COMING INTO CONTACT WITH THE BUMPY/SLICK ROAD SURFACE. THIS SUDDEN ACCELERATION RESPONDS TO BRAKING AND HAS OCCURRED APPROXIMATELY 5-8 TIMES, WITH MORE FREQUENCY SINCE THE RAINY WEATHER BEGAN. THIS IS FRIGHTENING FOR A FEW BRIEF SECONDS, ESPECIALLY IN HEAVY TRAFFIC. AS A CONSEQUENCE, I TRY TO AVOID UNEVEN ROAD SURFACES BUT IN HEAVY RAIN CONDITIONS WHEN THE ROAD IS COVERED WITH WATER, POT HOLES AND BRAKES IN THE BLACKTOP ARE NOT AS EASILY VISIBLE AND ONCE I SWERVED TO MISS IT BY MOVING INTO THE NEXT LANE A LITTLE BIT AND A BIG TRUCK WAS MERGING INTO THE SAME LANE AT THE SAME TIME AND BLEW HIS HORN SO HARD IT SCARED ME EVEN MORE SO THAT I SWERVED BACK INTO MY LANE, NEARLY CAUSING AN ACCIDENT. I PLAN TO CONTACT MY DEALER TODAY ABOUT THIS ACCELERATION DEFECT. *TR

I'VE ALSO EXPERIENCED BRAKING ISSUES WITH THE PRIUS. THIS USUALLY HAPPENS GOING OVER POTHOLES, ROUGH ROAD, OR RAILROAD TRACKS WHEN BRAKING AT CERTAIN SPEEDS WHILE APPLYING THE BRAKES AT MODERATE FORCE. IT MOMENTARILY FEELS LIKE THE CAR IS ACCELERATING - IT'S QUITE DISCONCERTING. I'VE ALSO NOTICED VARIABILITY IN BRAKING DISTANCE EVEN ON SMOOTH DRY PAVEMENT WHERE I'VE HAD TO STEP HARDER ON THE BRAKES BECAUSE THE CAR WASN'T STOPPING AS EXPECTED. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 2 MPH IN REVERSE AND REMOVING HIS FOOT FROM THE BRAKE, THE VEHICLE ACCELERATED ON ITS OWN. THE FAILURE HAS OCCURRED APPROXIMATELY 3 TO 4 TIMES. THE DEALER WAS CONTACTED AND HAD NOT RESPONDED WHEN THE COMPLAINT WAS FILED. THE CONTACT IS CONCERNED ABOUT THE SAFETY RISK INVOLVED AND DOESN'T FEEL SAFE DRIVING THE VEHICLE. NO REPAIRS WERE MADE TO THE VEHICLE. THE FAILURE MILEAGE WAS 2000. THE CURRENT MILEAGE WAS 5400.

I BOUGHT AT 2010 PRIUS ON 12/26/09 FROM THE VERY BEGINNING INTERMITTENTLY WHEN I GO TO STOP THE CAR WON'T STOP (MY CHEST TIGHTEN) ITS AS IF THE BACK OF THE CAR IS BEING PUSHED FORWARD EVEN THOUGH YOU HAVE YOUR FOOT ON THE BRAKE. YOU A GET A HESITATION AND THEN THE CAR STOPS. MY HUSBAND SAID IT WAS THE TRACTION CONTROL I WAS NOT USE TO IT.BUT THE TRACTION CONTROL LIGHT DOES NOT COME ON. ITS IS GETTING HARDER AND HARDER TO STOP. NOW EVEN THE PASSENGERS HEAR AND FEEL THE PROBLEM. YET WHEN I CALL TOYOTA TO BRING THE CAR IN THEY SAY THERE IS NO RECALL. *TR

I EXPERIENCE A FEW TIMES WEEK SINCE LAST SUMMER WHEN I GOT MY 2010 PRIUS THE "1 SECOND" BRAKE FAILURE THAT HAS BEEN REPORTED FOR 2010 PRIUS VEHICLES. AS AN OWNER OF SUCH VEHICLE, THE POTHOLE ON MY USUAL FREEWAY ON RAMP AND THE SPEED BUMP IN MY WORK'S PARKING GARAGE BOTH CAUSE A QUICK ACCELERATION FEELING FOR ABOUT 1/2 SECOND IF I'M APPLYING THE BRAKES AT THE MOMENT OF PASSING OVER THE POTHOLE OR SPEED BUMP. THAT 'FEELING' MAY BE NOT AN ACCELERATION BUT A MOMENTARY BRAKE FAILURE. THE FAILURE IS ONLY ABOUT 1/2 SECOND AND I'M USED TO IT NOW, THOUGH OBVIOUSLY IT IS AN UNSAFE SITUATION. IF I COME ACROSS SUCH EVENTS WHILE, SAY, BRAKING HARD WHEN I SEE A PEDESTRIAN IN THE PARKING LOT, I COULD FAIL TO AVOID HITTING THE PERSON. *TR

SUDDEN, UNINTENDED ACCELERATION--2010 PRIUS ON FREEWAY, ACCELERATED WITH GAS PEDAL TO 75. PUT ON CRUISE CONTROL. SEVERAL SECONDS LATER, CAR SURGED FORWARD, HARD AND SUDDEN ACCELERATION. FIRST TIME HAPPENED--THREE DAYS AGO, NOT DRIVEN SINCE. HAVE DONE NOTHING YET . *TR

I HAVE EXPERIENCED THE SAME ISSUES AS REPORTED FOR MY 2010 TOYOTA PRIUS: THE VEHICLE SURGED FORWARD OR TEMPORARILY LOST BRAKING(IN A SPLIT SECOND) AFTER DRIVING OVER A POTHOLE OR OTHER UNEVEN SURFACE. *TR

THE VEHICLE IS A VERY NEW PRIUS VERSION 3. THERE IS NO PROBLEM WITH THE FLOOR PADS. THERE DOES NOT SEEM TO BE A PROBLEM AT HIGHER SPEEDS. THE PROBLEM IS SHORT, UNEXPECTED BURSTS OF ACCELERATION AT LOWER SPEEDS, ESPECIALLY AS THE CAR IS SLOWING DOWN, WITH OR WITHOUT BRAKING. I BELIEVE IT OCCURS ESPECIALLY WHEN THE ENGINE SHIFTS FROM HYBRID TO ALL ELECTRIC. FOR EXAMPLE, ON A CURVING EXIT RAMP OFF A ROAD, AS THE CAR SLOWS, AND AS BRAKING AND ACCELERATION ARE RELEASED, AND THE CAR SHIFTS INTO PROPELLING ITSELF ON ELECTRIC, THERE IS A BURST OF ACCELERATION AT SOME TIME IN THIS MANEUVER. THIS HAS HAPPENED SEVERAL TIMES SINCE PURCHASING THE CAR A FEW WEEKS AGO. I SPOKE TO THE SERVICE MANAGER AT HE DEALERSHIP LAST WEEK. HE STATED HE KNEW NOTHING ABOUT THIS, AND HAD HEARD NORTHING FROM TOYOTA. HE OFFERED TO LOOK AT THE CAR IF I BROUGHT IT IN. SUBSEQUENTLY THE PRIUS PROBLEM BECAME NEWS.*TR

I OWN A 2010 PRIUS PURCHASED AROUND SEPT. 2009. A FEW WEEKS AFTER WE GOT THE VEHICLE, MY WIFE AND I INDEPENDENTLY BOTH EXPERIENCED A SUDDEN ACCELERATION WHEN THE CAR WENT OVER A BUMP. THIS HAS OCCURRED ABOUT A TOTAL OF 4 TIMES. MY FOOT WAS NOT ON THE ACCELERATOR AT THE TIME THIS OCCURRED. STEPPING ON THE BRAKE DID SLOW THE VEHICLE DOWN. THE LAST TIME I EXPERIENCED THIS WAS 2-3 WEEKS AGO. I DID ASK THE DEALER SHORTLY AFTER THE INITIAL INCIDENT IF HE HAD HEARD OF THIS PROBLEM AND HE SAID NO. I HAVE NOT SINCE BROUGHT THE CAR BACK TO THE DEALER. WE HAVE NOTICED THIS ONLY WHEN THE CAR GOES OVER A BUMP.*TR

WHILE DRIVING MY WIFE'S 2010 TOYOTA PRIUS FROM COLORADO SPRINGS TO ALAMOSA WE EXPERIENCED THE FOLLOWING ANOMALY. WE WERE ON THE FREEWAY (I-25) DRIVING SOUTH ON LEVEL TERRAIN WITH THE CRUISE CONTROL SET AT ~70MPH. I NOTICED A SIGNIFICANT INCREASE IN THE ENGINE RPM AND COULD SEE THE ENGINE DISPLAY FOR THE ENGINE IN THE PWR MODE. I DISENGAGED THE CRUISE CONTROL AND WAITED A SHORT PERIOD OF TIME AND REENGAGED THE CRUISE CONTROL. A SHORT TIME LATER (~15 MINUTES) THE RPM INCREASE OCCURRED AGAIN AND I ONCE AGAIN DISENGAGED THE CRUISE CONTROL. I DID NOT USE THE CRUISE CONTROL AGAIN ON THE TRIP. MY WIFE HAS USED THE CRUISE CONTROL RARELY SINCE HER USE DOES NOT INCLUDE FREEWAY DRIVING. *TR

ON AT LEAST TWO OCCASIONS, I HAVE HAD UNEVEN, JERKY ACCELERATION FROM MY 2010 TOYOTA PRIUS. ACCELERATION WAS FROM A STAND STILL AND WAS AT LOW RATES OF SPEED. BOTH INSTANCES HAVE OCCURRED WHEN THE VEHICLE WAS COLD, BUT THE AMBIENT AIR TEMPERATURE WAS PROBABLY ABOVE 30 DEGREES. *TR

BRAKING WHILE DRIVING OVER A POTHOLE CAUSES THE 2010 PRIUS TO MOMENTARILY FEEL LIKE IT'S ACCELERATING RATHER THAN BRAKING. THIS HAS RESULTED IN NEAR-ACCIDENTS A COUPLE OF TIMES. THIS HAPPENS MORE CONSISTENTLY WHEN TURNING WHILE BRAKING OVER UNEVEN PAVEMENT. I CAN REPEAT THIS RELIABLY IN SPECIFIC LOCATION, AND IT HAPPENS ELSEWHERE TOO.*TR

WHEN DRIVING AND BRAKING, IF YOU HIT A BUMP OR POT HOLE, THE BRAKES RELEASE AND THE CAR DOESN'T SLOW DOWN. THIS HAS HAPPENED A NUMBER OF TIME SINCE I BOUGHT THE CAR IN AUGUST 2009. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. WHILE DRIVING 20 MPH HE APPLIED THE BRAKE PEDAL; HOWEVER, THE VEHICLE DID NOT SLOW DOWN INSTEAD IT ACCELERATED AT VARIOUS SPEEDS. THE DEALER WAS UNABLE TO DUPLICATE THE FAILURE DURING A TEST DRIVE. HE STATED THAT THE FAILURE OCCURRED SIX TIMES INTERMITTENTLY CONTACT IS CONCERNED THAT IF HE CONTINUED TO DRIVE THE VEHICLE THE FAILURE COULD CAUSE A CRASH TO OCCUR. THE FAILURE MILEAGE WAS 9,000 AND THE CURRENT MILEAGE WAS 10,500.

2010 PRIUS WHICH LURCHED FORWARD EACH TIME I HIT A CERTAIN POTHOLE WHILE BRAKING. I AVOIDED THE PROBLEM BY AVOIDING THE POTHOLE. THE POTHOLE WAS LOCATED NEAR A STOP SIGN, SO I WAS ALWAYS BRAKING WHEN I HIT IT. *TR

CAR DID NOT BRAKE PROPERLY AND SLIGHTLY SURGED FORWARD ON MANY OCCASIONS WHEN I DROVE OVER A MANHOLE COVER AND SPEED BUMPS AT LOWER SPEEDS. IN ONE OCCASION, I REAR ENDED A CAR AND CRACKED MY LICENSE PLATE FRAME BUT SINCE THERE WAS NO FURTHER DAMAGE ON ANY OF THE CARS INVOLVED, WE AGREED TO DRIVE AWAY. *TR

I HAVE A 2010 TOYOTA PRIUS THAT I BOUGHT IN DECEMBER, 2009. SIX OR SEVEN TIMES, I HAVE NOTICED THAT THE CAR LURCHES FORWARD (LIKE SOMEONE IS FLOORING THE GAS PEDAL) EVERY TIME I HIT A POT HOLE. I THOUGHT IT MIGHT BE JUST ME, BUT I SAW IN THE PAPER TODAY THAT OTHERS HAVE NOTICED SIMILAR PROBLEMS WITH THEIR PRIUS. *TR

WHILE TURNING OFF FOUR LANE ROAD ONTO FRONTAGE ROAD WITH FOOT ON BRAKE PEDAL MY CAR SUDDENLY STARTED ACCELERATING. I APPLIED MORE PRESSURE ON THE PEDAL QUICKLY AND GOT A SORT OF CLUNKING SOUND AND THE CAR RETURNED TO NORMAL DRIVING SPEED? *TR

2010 TOYOTA PRIUS. I HAVE EXPERIENCED ON AT LEAST 3 OCCASIONS, A SURGE WHEN GOING OVER A BUMP OR POTHOLE. I SPOKE TO MY LAW PARTNER ABOUT IT YESTERDAY. TODAY HE SHOWED ME THE INVESTIGATION YOU HAVE OPENED INTO THIS ISSUE. *TR

I WAS DRIVING MY 2010 TOYOTA PRIUS USING CRUISE CONTROL ON A HIGHWAY. I DISENGAGED CRUISE CONTROL TO SLOW DOWN AS A VEHICLE ENTERED THE HIGHWAY IN FRONT OF ME. ONCE THE SECOND VEHICLE HAD ACCELERATED AHEAD, I RE-ENGAGED CRUISE CONTROL AT MY DESIRED SPEED. THE CRUISE CONTROL ENGAGED, BUT CONTINUED ACCELERATION, AS IF I WAS ACTIVATING THE CRUISE CONTROL MECHANISM'S ACCELERATE "PADDLE", WHICH I WAS NOT ACTUALLY DOING. I IMMEDIATELY DIS-ENGAGED CRUISE CONTROL, SLOWED TO MY DESIRED SPEED, AND RE-ENGAGED CRUISE CONTROL. AT THIS POINT, THE CRUISE CONTROL RESUMED PROPER OPERATION AND I WAS ABLE TO DRIVE AT MY SELECTED SPEED. *TR

DESIGN FLAW ON A BRAND NEW 2010 TOYOTA PRIUS THAT MAKES RATTLING NOISE NEAR THE GEAR SHIFT LEVER THAT COULD BRAKE THE GEAR LEVER. *TR

I HAVE EXPERIENCED A SUDDEN ACCELERATION TYPE PROBLEM WHEN DRIVING OVER ROUGH PAVEMENT AND POTHOLES, ETC. THE ACCELERATION IS FOR A SPLIT SECOND AND I SUSPECT IT MAY BE RELATED TO THE LACK OF TRACTION FROM THE TIRES. IT DOES NOT APPEAR TO HAVE ANYTHING TO DO WITH LOOSE FLOOR MATS OR A STICKING PEDAL. NO REPAIRS HAVE BEEN MADE. DEALER SAID THEY NEVER HEARD OF THE PROBLEM WHEN I WENT IN LAST WEEK. I WAS OFFERED TO HAVE IT BROUGHT INTO SERVICE DEPART. IT DOES NOT HAPPEN ON COMMAND SO I AM GOING TO WAIT FOR NHTSA INVESTIGATION. *TR

I PURCHASED A NEW 2010 TOYOTA PRIUS IN SEPTEMBER 2009 FROM DARCARS TOYOTA IN FREDERICK MD. I HAVE EXPERIENCED (2) INSTANCES OF UNINTENDED ACCELERATION DURING THE TIME SINCE I PURCHASED THE VEHICLE. I HAVE INFORMED DARCARS TOYOTA AND TOYOTA CORPORATION. DARCARS RAN A "HEALTH TEST" ON FEBRUARY 4, 2009 ON MY VEHICLE AND THE TEST INDICATED EVERYTHING ON THE VEHICLE WAS OPERATING NORMALLY. DARCARS THEN CONTACTED THEIR TOYOTA CALIFORNIA (TAC) AND RELATED MY PROBLEM TO THEM. THE RESPONSE FROM TOYOTA WAS THAT MY EPISODES OF UNINTENDED ACCELERATION WAS JUST THE ABS SYSTEM ENGAGING NORMALLY. THIS IS AFTER THE PRESS RELEASE FROM TOYOTA CORPORATION ON THE MORNING OF 02/04/10 ACKNOWLEDGING A PROBLEM EXISTING WITH THE 2010 PRIUS BUT CLAIMING TO HAVE ALREADY FIXED THE PROBLEM ON ALL NEW 2010 PRIUS AUTOMOBILES SOLD SINCE JANUARY 2010. MY TWO QUESTIONS ARE 1) IF TOYOTA DISCOVERED A PROBLEM WITH THE 2010 PRIUS THAT THEY SUPPOSEDLY REPAIRED ON ALL 2010 PRIUS VEHICLES SOLD SINCE JANUARY, WHY HAS TOYOTA NOT CONTACTED ME ABOUT WHAT IS AN OBVIOUS SAFETY ISSUE? I HAVE OWNED AND BEEN DRIVING MY 2010 PRIUS SINCE SEPTEMBER '09. 2) WHAT IS THE SPECIFIC REPAIR THAT WAS SUPPOSEDLY PERFORMED ON ALL 2010 PRIUS AUTOMOBILES SINCE JANUARY 1, 2010? WHY DID MY TOYOTA SERVICE MANAGER HAVE NO KNOWLEDGE OF SUCH A REPAIR? WAS THERE A SAFETY BULLETIN ISSUED BY TOYOTA? WHY HAS TOYOTA NOT ALREADY AGREED TO REPAIR MY 2010 PRIUS (SOLD IN SEPTEMBER '09) WITH THE SAME REPAIR ALLEGEDLY ALREADY PERFORMED ON 2010 PRIUS AUTOMOBILES SOLD AFTER JANUARY 1, 2010? *TR

SUDDEN UNINTENDED ACCELERATION, MOMENTARILY LOSES BRAKING WHEN IT GOES OVER UNEVEN ROADS, POTHOLES ..ETC. OCCURS SEVERAL TIMES A DAY. *TR

MY 2010 PRIUS (PURCHASED 6/30/09) LURCHES FORWARD WHEN I HIT A POTHOLE OR A SHARP BUMP IN THE ROAD WHILE I HAVE THE BRAKES ON. IT HAS HAPPENED ABOUT 3 TIMES SINCE I'VE HAD THE CAR. *TR

ON 8-21-09, I TOOK DELIVERY ON A 2010 TOYOTA PRIUS HYBRID. SINCE TAKING DELIVERY, I HAVE EXPERIENCED INTERMITTENT ,MOMENTARY ,UNINTENDED ACCELERATION AND INTERMITTENT,MOMENTARY LOSS OF BRAKING. ON 1-10-10, I TOOK IT IN FOR THE 5000 MILE MAINTENANCE CHECK, BUT DID NOT TELL THE DEALER MY PROBLEMS ,BECAUSE I THOUGHT THE CAR WAS STILL IN A "BREAKING IN" PERIOD AND WOULD RESOLVE ITSELF. BUT WHEN I HEARD TODAY 2-4-10, THAT THE NHTSA WAS OPENING AN INVESTIGATION OF THE 2010 PRIUS, I DECIDED TO ADD MY COMPLAINT TO THE OTHERS. *TR UPDATED 03/04/10 *BF

I OWN A 2010 TOYOTA PRIUS THAT I PURCHASED IN THE FALL OF 2009. ON SEVERAL OCCASIONS I HAVE DEPRESSED MY BRAKE PEDAL TO EITHER SLOW DOWN OR STOP BUT , INSTEAD, THE VEHICLE BRIEFLY ACCELERATES AND GIVES A FEELING OF "SKIPPING" OVER THE BRAKING ACTION. THE VEHICLE THEN QUICKLY CORRECTS BEFORE STOPPING OR SLOWING DOWN. THIS HAS HAPPENED ON MORE THAN ONE OCCASION ON VERY SPECIFIC TYPES OF TERRAIN THAT I CAN DESCRIBE AS BUMPY OR UNEVEN. I PLACED A CALL TODAY WITH MY TOYOTA DEALERSHIP IN WHICH I EXPLAINED THE ABOVE NARRATIVE TO THEM. THEY RESPONDED WITH IGNORANCE TO THE SITUATION AND STATED THAT THEY WILL WAIT TO HEAR FROM TOYOTA ON THE MATTER. *TR

TOYOTA 2010 PRIUS - PROBLEM WITH CAR ACCELERATING WHEN I BRAKE ON BUMPY SURFACE. HAS OCCURRED REPEATEDLY AS ON MY DRIVE TO WORK I DRIVE OVER A POTHOLED SECTION OF ROAD AND NEED TO BRAKE TO SLOW DOWN FOR A RIGHT HAND TURN -IF I GO VERY SLOWLY AND DO NOT BRAKE ON THE BUMPY PART IT DOES NOT OCCUR - WHEN I DRIVE AT A NORMAL SPEED AND BRAKE FOR THE TURN IT DOES OCCUR - I FEEL A MAJOR ACCELERATION THAT LASTS FOR ONLY A SECOND OR TWO. *TR

WHILE DRIVING WITH CRUISE CONTROL ENGAGED AND A SITUATION OCCURS THAT REQUIRES BRAKING; NORMAL BRAKE PEDAL PRESSURE DOES NOTHING. I HAVE TO HIT THE BRAKES EXTRA HARD WHICH SIGNIFICANTLY SLOWS REACTION TIME. THIS PROBLEM OCCURS RANDOMLY. WHEN I TOOK THE CAR TO THE DEALER I COULD NOT GET THE PROBLEM TO REPEAT. *TR

AT 8:00 AM THIS MORNING, I WAS DRIVING THROUGH A STREET AT A SPEED OF 20 MILES TO 30 MILES PER HOUR. SUDDENLY, THE CAR JUMPED A LITTLE PROBABLY HIT A SMALL POTHOLES OR BUMPS. I FELT LIKE THE CAR SURGED FORWARD OR MAY BE THE BRAKE DIDN'T RESPOND IMMEDIATELY. FORTUNATELY, NO OTHER CAR RIGHT IN FRONT OF ME AND THE CAR SPEED IS NOT VERY FAST. I WAS ABLE TO BRAKE IT AND SLOW DOWN. I HAVE CALLED THE DEALER AND THE SERVICE REPRESENTATIVE DOESN'T THINK IT IS A PROBLEM. LATER, I ALSO SENT A FAX TO TOYOTA US HEADQUARTER ASKING FOR HELP. *TR

I PURCHASED A BRAND NEW 2010 TOYOTA PRIUS V ON SEPTEMBER 24, 2009. IT PERFORMED BEAUTIFULLY, AND WAS A REAL PLEASURE TO DRIVE. HOWEVER, A MONTH OR SO LATER, WITH THE CAR IN REVERSE, I STARTED BACKING OUT OF A PARKING PLACE AND IMMEDIATELY NOTICED AN UNUSUALLY INTENSE "REVVING" OF THE ENGINE. STARTLED, I IMMEDIATELY PRESSED ON THE FOOT BRAKE, RELEASING IT IN LITTLE STEPS UNTIL THE CAR WAS "INCHED" OUT OF THE PARKING PLACE. I THEN SHIFTED THE LEVER INTO "DRIVE" AND PROCEEDED ON MY WAY QUITE NORMALLY WITHOUT ANY FURTHER PROBLEM WHATSOEVER. IN THE ENSUING MONTHS, THIS STRANGE PHENOMENON HAS ONLY REPEATED ITSELF TWO MORE TIMES OUT OF HUNDREDS OF BACKOUTS FROM PARKING SLOTS. THERE HAS BEEN NO OTHER CIRCUMSTANCE IN WHICH THIS SEVERE " REVVING" HAS RE-OCCURRED. IN THE AFOREMENTIONED THREE CASES, I HAD NO RECOLLECTION WHATSOEVER OF PRESSING THE FOOT THROTTLE, AND THEREFORE HAVE PRESUMED THAT THE PROBLEM IS IN THE ELECTRONICS OR SOFTWARE, RATHER THAN IN THE FLOOR THROTTLE MECHANICS. IN EVERY OTHER RESPECT SO FAR, MY 2010 TOYOTA PRIUS V HAS PERFORMED PERFECTLY. *TR

I TOO HAVE NOTICED A STRANGE FEELING OF SPEEDING UP INSTEAD OF SLOWING DOWN WHEN DRIVING OVER A LARGE BUMP ON A STREET IN MY 2010 PRIUS. *TR

I HAVE A 2010 TOYOTA PRIUS. SOMETIMES, PARTICULARLY WHEN I'M DRIVING OVER BUMPS, APPLYING THE BRAKE ACTUALLY CAUSES THE VEHICLE TO NUDGE FORWARD INSTEAD OF SLOWING DOWN. ONCE I HAVE CLEARED THE BUMPS, THE BRAKES THEN TAKE EFFECT. THE PROBLEM IS THAT THE CAR MAY NOT ACTUALLY SLOW DOWN FOR AN EXTRA 10 TO 20 FEET. THERE WAS ONE INCIDENT WHERE THIS HAPPENED NEAR A CROSSWALK WHERE PEOPLE WERE CROSSING THE ROAD. THE CAR STOPPED IN TIME, BUT THIS COULD HAVE EASILY TURNED TRAGIC. TOYOTA HAS SAID NOTHING ABOUT THIS AND DON'T THINK THERE IS ANYTHING WRONG WITH THE CAR. *TR

MY TOYOTA PRIUS 2010 (5000 MILES) FEW TIMES ALREADY HAS AN "ACCELERATOR THAT GOES WILD", BUT LUCKILY FOR ME, I CAN HIT THE BRAKES. IT HAPPENED ONLY WHEN I DRIVE BACK FROM MY GARAGE. *JB

2010 TOYOTA PRIUS. GOING DOWNHILL AND APPROACHING A STOP SIGN. MY FOOT IS STEADY ON THE BRAKE AND I AM GRADUALLY COMING TO A STOP. THEN, I INADVERTENTLY GO OVER A BUMP IN THE ROAD AND THE PRIUS LUNGES FORWARD. I HAD TO IMMEDIATELY SLAM HARD ON THE BRAKES IN ORDER TO KEEP THE CAR FROM GOING INTO THE INTERSECTION. FORTUNATELY, THERE WAS NO CAR OR PERSON IN FRONT OF ME AS I WAS STOPPING. *TR

2010 TOYOTA PRIUS ACCELERATES WHEN BRAKE IS PRESSED. THE VEHICLE SEEMS TO JUMP FORWARD DEPENDING ON ROAD CONDITIONS. IT SEEMS TO BE THE ANTI LOCK BRAKES. THE PROBLEM USUALLY OCCURS 2 TO 3 TIMES A MONTH. *TR

I OWN A 2010 TOYOTA PRIUS. AT LEAST 10 TIMES, WHEN PASSING OVER A BUMP OR POTHOLE IN THE ROAD, THE CAR ACCELERATES WITHOUT MY APPLYING ANY PRESSURE TO THE GAS PEDAL. THAT IS, IT ACCELERATES WITHOUT WARNING SOMETIMES WHEN I PASS OVER A BUMP OR POTHOLE. THEN, WHEN I TRY TO SLOW IT DOWN FROM THIS UNWANTED ACCELERATION, THE BRAKES DO NOT SEEM TO FUNCTION PROPERLY. THAT IS, THE BRAKES DO NOT SEEM TO PROPERLY AND INSTANTLY "CATCH" TO SLOW THE CAR. RATHER, THERE IS A PULSATING SENSATION FOR AN ESTIMATED 2-5 SECONDS UNTIL THE BRAKES FINALLY AND COMPLETELY "CATCH" TO SLOW THE CAR FROM THE UNWANTED AND UNINTENDED ACCELERATION. I NOTICED THIS SHORTLY AFTER BUYING THE CAR ON AUGUST 11, 2009. FURTHER, I HAVE NEVER EXPERIENCED THIS PHENOMENON WITH ANY OTHER AUTOMOBILE THAT I HAVE DRIVEN IN THE LAST 30 YEARS. IT IS NOT SOME PHENOMENON OR PROBLEM THAT HAS DEVELOPED OVER TIME. RATHER, IT WAS A PHENOMENON THAT OCCURRED WHEN THE CAR WAS ALMOST COMPLETELY NEW WITH FAR LESS THAN 1,000 MILES ON THE ODOMETER. I AM MAKING THIS COMPLAINT AFTER READING IN AN INTERNET NEWS ARTICLE THAT OTHERS ARE EXPERIENCING SIMILAR PROBLEMS WITH THE 2010 TOYOTA PRIUS AS WELL AS THE OTHER RECALLED TOYOTA AUTOMOBILES. I BELIEVE THIS IS A POTENTIALLY DANGEROUS PROBLEM, AND SWIFT U.S. GOVERNMENT ACTION IS BOTH WARRANTED AND NEEDED FOR PUBLIC SAFETY. *TR

THE BRAKING SYSTEM TEMPORARILY DISENGAGES WHEN HITTING A BUMP, MANHOLE, GRAVEL, ETC. CAUSING CAR TO LUNGE FORWARD. TOYOTA OF NAPERVILEE TOLD ME THAT SOME LUNGING IS TO BE EXPECTED. IT IS SCARY WHEN THIS PROBLEM OCCURS BECAUSE YOU HAVE NO CONTROL OF THE BRAKES. I'M CONCERNED THAT IT MAY RESULT IN A FUTURE ACCIDENT. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED HIS VEHICLE ACCELERATES ON ITS OWN WHEN HE STEPS ON THE BRAKES. THE CONTACT TOOK HIS VEHICLE TO THE DEALER AND THEY STATED THERE WAS NO PROBLEM WITH THE ACCELERATOR PEDAL. THE CONTACT STATED HE HEARD ABOUT THE PROBLEM ON THE NEWS AND HE WAS REPORTING THE PROBLEM. THE FAILURE MILEAGE WAS 2,010.

I HAVE A 2010 PRIUS AND WHEN I DROVE OVER A BUMP OR POT HOLE MY CAR FAILS TO ACCELERATE FORWARD AND LOSE ANY BRAKING FEELING (ALMOST TO WHERE I LOSE CONTROL OF THE CAR). IT HAPPENS ONLY FOR A SHORT MOMENT. *TR

I SAW AN ARTICLE ABOUT THE 2010 PRIUS LUNGING WHEN HITTING A BUMP OR POTHOLE. I OWN ONE AND HAVE HAD THE EXPERIENCE ON MORE THAN 1 OCCASION. *TR

2010 TOYOTA PRIUS- CAR TENDS TO ACCELERATE AFTER HITTING SOME POTHOLES OR BUMPS IN THE ROAD WHEN THE BRAKE IS DEPRESSED. THE FIRST COUPLE OF TIMES, I CAME VERY CLOSE TO REAR-ENDING THE CAR IN FRONT OF ME BECAUSE THE BUMP OR POTHOLE WAS IN THE ROAD AT A TRAFFIC LIGHT AND I WAS ATTEMPTING TO STOP. I HAVE BEEN ABLE TO REPEAT INCIDENT BUT NOT ALL OF THE TIME (MAY DEPEND ON HOW HARD THE BRAKE IS DEPRESSED OR HOW FAST THE CAR IS GOING AT THE TIME). I NOTICED THIS SHORTLY AFTER PURCHASING AND RECEIVING THE CAR ON 24 OCT. 2009. MENTIONED TO TOYOTA SERVICE STAFF AT A NEW CAR ORIENTATION PROGRAM, BUT WAS TOLD THAT THEY HAD NOT HEARD OF THIS ISSUE... AND PERHAPS THE BUMPS IN THE ROAD WERE CAUSING ME TO NOT APPLY EVEN PRESSURE ON THE BRAKE. I HAVE ADJUSTED MY DRIVING ROUTE AS TO NOT TO GO OVER THE POTHOLE WHICH CAUSES THE MOST PROBLEMS (OR TRY TO BE VIGILANT ABOUT SITUATIONS WHICH MAY CAUSE LURCHING) BUT WAS CONCERNED WHEN I SAW AN ARTICLE REPORTING THAT OTHER PEOPLE ARE EXPERIENCING SIMILAR ISSUES (HTTP://WWW.FREEP.COM/ARTICLE/20100203/BUSINESS01/100203028/1318/2010-PRIUS-OWNERS-COMPLAIN-OF-FAULTY-BRAKES-LURCHING-OVER-BUMPS). *TR

I HAVE A 2010 PRIUS. I HAVE HAD 2 OCCASIONS WHERE I HAVE HIT BUMPS IN THE ROAD AND MY CAR ACCELERATES WITHOUT ME TOUCHING THE GAS PEDAL. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRUIS. THE CONTACT STATED THAT WHILE DRIVING IN REVERSE WITH HER FOOT ON THE BRAKE PETAL, THE VEHICLE ACCELERATED ON ITS OWN. THE CONTACT THEN APPLIED THE BRAKES AND IT STOPPED. SHE THEN TURNED OFF THE VEHICLE AND IT DROVE NORMALLY. THE ISSUE HAS OCCURRED A TOTAL OF 5 TIMES. THE VEHICLE HAD NOT BEEN DIAGNOSED AT THE TIME OF THE COMPLIANT.THE DEALER WILL BE CONTACTED. THE FAILURE MILEAGE WAS UNKNOWN AND CURRENT MILEAGE WAS 2500.

MY 2010 TOYOTA PRIUS SUDDENLY SURGED FORWARD FOR A FEW FEET AFTER GOING OVER A LITTLE BUMP IN THE ROAD (LIKE A MANHOLE COVER). THIS HAPPENED A COUPLE OF TIMES. NO INJURIES OR ACCIDENTS. I BROUGHT THIS TO THE ATTENTION OF MY DEALER WHEN I BROUGHT IT IN TO CHANGE THE OIL @ 5000 MILES. THEY SAID THEY COULD NOT REPLICATE OR DETECT THE PROBLEM. I HAVE NOT HAD ANY SUCH INCIDENTS IN THE PAST 2 MONTHS. *TR

I DRIVE A 2010 TOYOTA PRIUS AND WOULD LIKE TO REPORT THAT WHEN BRAKING, IF I HIT A POT HOLE OR BUMP, THE CAR LUNGES FORWARD OR ACCELERATES FOR A SPLIT SECOND. I HAVE HAD MY CAR FOR JUST UNDER 60 DAYS BUT HAVE HAD THIS EXPERIENCE AT LEAST A DOZEN TIMES. IT HAS NOT CAUSED AN ACCIDENT, BUT LEAVES ME FEELING AS IF THERE ARE MOMENTS THAT I DO NOT HAVE CONTROL OF MY CAR. IT'S LIKE IT HAS A MIND OF IT'S OWN! *TR

I HAVE BEEN DRIVING MY 2010 PRIUS FOR ALMOST 6 MONTHS NOW AND HAVE EXPERIENCED THE CAR JERKING FORWARD AND FOR A FEW SECONDS SPEEDING UP AS IF THE BRAKE DOESN'T WORK. THIS HAPPENS SPECIFICALLY IF A POTHOLE OR BUMP IN THE ROAD IS HIT AND I'M BRAKING. MOSTLY WHEN SLOWING DOWN BY HITTING THE BRAKE. I ACTUALLY NOTICED THIS ALMOST IMMEDIATELY WHEN I BOUGH THE CAR BUT SINCE I'VE BEEN READING UP A LOT ABOUT THE 2010 PRIUS NOT IN THE TOYOTA RECALL LIST, I THOUGHT IT IS IMPORTANT TO REPORT IT AND GET IT FIXED. ONE EXPERIENCED THE STRANGEST FEELING WHEN THIS HAPPENS. ALMOST AS IF THE BREAK PEDAL IS HIT AND THE CAR JERKS FORWARD AS IF THE PEDAL IS STUCK AND THE CAR BODY MOVES FORWARD. *TR

2010 TOYOTA PRIUS. ACCELERATION WHEN APPLYING BRAKE IN BUMPY ROAD. IT HAPPENED WHEN THE SPEED IS SLOW AND THERE IS UNEVEN OR DRIVES OVER POT HOLE. *TR

SUDDEN SURGE WHEN HITTING A BUMP AT MEDIUM SPEEDS. MY PRIUS IS NOW SIX MONTHS OLD WITH ABOUT 6,000 MILES ON IT AND I EXPERIENCE A SURGE IN ACCELERATION WHEN I HIT A BUMP AT ABOUT 20 MPH. I USED TO BE AN AUTO MECHANIC (20 YEARS AGO), SO I MAY BE A LITTLE MORE ATTUNED TO NARROWING THE PROBLEM THAN MOST PEOPLE. I HAVE NOTICED THAT WHEN THIS SURGE HAPPENS I AM LIGHTLY ON THE BRAKES (TOTALLY OFF THE ACCELERATOR). THIS SEEMS TO PARTICULARLY HAPPEN WHEN THE BUMP (LIKE A POTHOLE IN THE ROAD) IS UNDER THE RIGHT FRONT WHEEL. EVEN MORE FRUSTRATING IS THAT THIS DOES NOT HAPPEN EVERY TIME NOR ON EVERY BUMP. I CAN TELL YOU THE FLOOR MAT HAS NOTHING TO DO WITH IT AND I DO NOT THINK THE OUTSIDE TEMPERATURE HAS ANYTHING TO DO WITH IT EITHER. MY SHADETREEMECHANIC'S DIAGNOSIS IS THAT THIS IS A SOFTWARE GLITCH THAT GETS ACTIVATED WHEN THE BRAKING SOLENOID IS BUMPED. *TR

2010 PRIUS ACCELERATES WHEN DRIVING OVER SPEED BUMP, POT HOLE OR OTHER UNEVEN SURFACES. *TR

TOYOTA PRIUS 2010, SUDDEN SURGE OF POWER, WHEN SLOWING OR BRAKING TO COME TO A STOP. EXTREMELY DANGEROUS IN TRAFFIC OR WHEN PARKING. HAVE REPORTED TO TOYOTA, WHO CLAIMED NO KNOWLEDGE OF PRIUS'S HAVING THIS DEFAULT. ANOTHER SAID THIS WAS A COMMON FUNCTION OF THE HYBRIDS. RECENT SERVICE DEPT. CLAIMED CHECKED BUT FOUND NO EVIDENCE. THIS PROBLEM HAPPENS INTERMITTENTLY. BECAUSE WE KNOW OF THIS PROBLEM, ARE EXTRA CAUTIOUS. *TR

WHEN DRIVING MY 2010 TOYOTA PRIUS THE CAR HAS A TENDENCY TO ACCELERATE FORWARD AS I AM HITTING THE BRAKES. I HAVE NOTICED THIS IS USUALLY AROUND POTHOLES OR ANY OTHER BUMPS IN THE ROAD. IT HAPPENS PRETTY REGULARLY AND IT SCARES THE PANTS OFF ME; TO SAY THE LEAST. I HAVE FOUND NO RESPONSE FROM TOYOTA CONCERNING FIXING THIS PROBLEM AND AM WORRIED THAT WHEN SOMETHING BAD HAPPENS I'LL BE HELD RESPONSIBLE FOR THEIR MISTAKE. *TR

WE LIVE IN CHICAGO AND OWN A 2010 PRIUS. WE ALSO HAVE EXPERIENCED THE ACCELERATION (FORWARD SURGE) UPON BRAKING ON UNEVEN TERRAIN REPORTED BY OTHER OWNERS. NO ACCIDENT, BUT IT HAPPENS OFTEN ON OUR CITY STREETS AND IT IS A LITTLE UNNERVING. THE LAST TIME IT HAPPENED WAS YESTERDAY. *TR

I OWN A 2010 PRIUS, AND HAVE EXPERIENCED AN ACCELERATION ISSUE ON ABOUT 3-4 OCCASIONS SINCE PURCHASING THE VEHICLE IN AUGUST OF 2009. THE ISSUE I HAD WAS PERFECTLY DESCRIBED IN A RECENT ON-LINE ARTICLE FROM MONEY.CNN.COM ON FEB 3. HERE IS THE QUOTE - "THE COMPLAINTS RECEIVED VIA OUR DEALERS CENTER AROUND WHEN DRIVERS ARE ON A BUMPY ROAD OR FROZEN SURFACE," A TOYOTA MOTOR CORP. SPOKESMAN IN JAPAN, SAID. "THE DRIVER STEPS ON THE BRAKE AND THEY DO NOT GET AS FULL OF A BRAKING FEEL AS EXPECTED." THIS IS EXACTLY WHAT I'VE EXPERIENCED, AND IT ALSO SEEMS TO POSSIBLY BE RELATED TO THE SHIFT FROM GAS TO ELECTRIC WHICH OCCURS WHEN SLOWING DOWN. AFTER BRAKING, THERE IS A SUDDEN, BRIEF SURGE OF ACCELERATION. I HAVE NOT BROUGHT THIS INTO THE DEALER, BUT PLAN TO SOON. *TR

I HAVE A 2010 TOYOTA PRIUS. APPROXIMATELY 10 TIMES SINCE I BOUGHT THE CAR IN JULY 2009 IT HAS JOLTED FORWARD WHILE I AM APPLYING THE BRAKES WHEN I DRIVE OVER A POTHOLE OR BUMP IN THE ROAD. *TR

I PURCHASED MY 2010 TOYOTA PRIUS IN DECEMBER 2010. TWICE IN THE LAST TWO WEEKS MY CAR HAS UNEXPECTEDLY LURCHED FORWARD AS I WENT OVER A SPEED BUMP AT A RELATIVELY LOW SPEED. SINCE IT WAS THE SAME SPEED BUMP BOTH TIMES, I REASON THAT IT MUST HAVE SOMETHING TO DO WITH THE HEIGHT OF THE BUMP AND/OR MY ANGLE OF APPROACH. I WAS ABLE TO REGAIN CONTROL OF THE VEHICLE BOTH TIMES. I AM REPORTING THIS BECAUSE I HAVE READ THE NEWS ARTICLES ABOUT OTHERS HAVING SIMILAR PROBLEMS WITH 2010 PRIUS' AND THOUGHT THAT YOU WOULD WANT TO KNOW. I HAVE NOT TAKEN ANY ACTION BECAUSE I WASN'T SURE THE PROBLEM WAS WITH THE VEHICLE OR THE ROAD SURFACE. *TR

THE BRAKES MOMENTARILY RELEASE/SKIP WHEN BRINGING THE VEHICLE TO A STOP WHILE PASSING OVER A BUMP OR POTHOLE IN THE ROAD. THIS HAS BEEN HAPPENING ON A REGULAR BASIS SINCE I BOUGHT THE CAR IN JULY 2009. *TR

SINCE PURCHASING MY 2010 PRIUS IN AUGUST, I HAVE EXPERIENCED MULTIPLE EPISODES OF CAR FEELING AS IF IT WERE SUDDENLY ACCELERATING WHEN GOING OVER BUMPS, POTHOLES OR OTHER IRREGULARITIES IN THE ROAD. I BELIEVE WHEN THIS HAPPENS I OFTEN ALREADY HAVE MY FOOT ON THE BRAKE, BUT I FIND MYSELF HAVING TO SLAM THE BRAKE ON HARDER TO PREVENT WHAT IS AT LEAST A STRONG SENSATION OF THE CAR "TAKING OFF". FEELS JUST LIKE WHEN RIDING A HORSE AND IT IS ABOUT TO BOLT! WENT TO DEALER IN SEPTEMBER OR OCTOBER, AND THEY COMPLETELY BLEW ME OFF, SAID "NOTHING IS WRONG", NO OTHER REPORTS OF THIS HAPPENING (CLEARLY A LIE IT NOW APPEARS). *TR

WAS PARKING ON SLIGHT INCLINE FACING DOWNHILL. HIT BRAKE TO PUT CAR IN PARK, BUT CAR LURCHED FORWARD, OVER CONCRETE BUMPER IN FRONT OF PARKING SPACE. JUST HAPPENED, HAVE NOT TAKEN CORRECTIVE MEASURES YET. ALSO HAVE NOTICED CAR LURCHING FORWARD WHEN SLOWING AROUND TURNS, HAS NOT CAUSED SIGNIFICANT PROBLEMS YET, NO ACTION TAKEN YET. *TR

WE OWN A 2010 PRIUS. MY DAUGHTER USUALLY DRIVES IT. I HAD IT FOR THE MONTH OF JANUARY. DURING THAT TIME, I EXPERIENCED BRIEF SURGES OR SWERVES WHEN I HIT POTHOLES OR ROUGH SPOTS IN THE ROAD AT A SLOW SPEED. THIS OCCURRED 3 OR 4 TIMES OUT OF APPROXIMATELY TWO DOZEN SHORT TRIPS AROUND TOWN. *TR

AS I WAS APPROACHING A STOP LIGHT, I TOOK MY FOOT OFF OF THE GAS PEDAL OF MY 2010 TOYOTA PRIUS TO HIT THE BRAKE WHEN ALL OF THE SUDDEN MY VEHICLE ACCELERATED AND SURGED FORWARD. IT DID NOT STOP UNTIL I SLAMMED MY FOOT ON THE BRAKE. THIS HAS NOT HAPPENED SINCE AND I HAD ASSUMED IT WAS A FREAK ACCIDENT, BUT I WANTED TO REPORT IT IN LIGHT OF THE TOYOTA RECALLS THAT HAVE OCCURRED. *TR

THERE HAVE BEEN SEVERAL INSTANCES SINCE I PURCHASED MY 2010 PRIUS IN OCTOBER 2009 THAT I HAVE GONE OVER A BUMP IN THE ROAD AND MY 2010 PRIUS HAS FELT LIKE IT'S SPEEDING UP AND I HAD TO PUSH HARD ON THE BRAKES TO FEEL LIKE I HAD CONTROL OF MY CAR. *TR

2010 TOYOTA PRIUS. GOING DOWNHILL AND APPROACHING A STOP SIGN. MY FOOT IS STEADY ON THE BRAKE AND I AM GRADUALLY COMING TO A STOP. THEN, I INADVERTENTLY GO OVER A BUMP IN THE ROAD AND THE PRIUS LUNGES FORWARD. I HAD TO IMMEDIATELY SLAM HARD ON THE BRAKES IN ORDER TO KEEP THE CAR FROM GOING INTO THE INTERSECTION. FORTUNATELY, THERE WAS NO CAR OR PERSON IN FRONT OF ME AS I WAS STOPPING. (I LOOKED AT PRIOR COMPLAINTS AND THIS MATCHES MINE). *TR

2010 PRIUS SEEMS TO LURCH FORWARD WHEN DRIVING OVER POTHOLES AND OTHER BUMPS WHILE BRAKING. THIS HAS HAPPENED NEAR INTERSECTIONS AND WHEN TURNING INTO PARKING LOTS. THE CAR SEEMS TO SPEED UP BRIEFLY, ENOUGH TO SCARE THE DRIVER. I'VE ALMOST ROLLED THROUGH STOP SIGNS AND NEARLY RUN OVER A FEW CARS WHEN TURNING INTO PARKING LOTS. *TR

2010 TOYOTA PRIUS SPONTANEOUS ACCELERATION WHILE BRAKING OVER BUMPS, POT HOLES AND SLICK ROADWAYS. *TR

2010 TOYOTA PRIUS HAS A DEFECT THE TOYOTA HAS ACKNOWLEDGED. THE PROBLEM IS WHEN THE CAR HITS A LARGE BUMP THE CAR ACCELERATES. THE DASH TRACTION WARNING LIGHT ALSO COMES ON AND TOYOTA IS SAYING THEY BELIEVE THIS IS A SOFTWARE PROBLEM. *TR

I HAVE A 2010 PRIUS. WHEN I AM BRAKING AND HIT SOME BUMPS IN THE ROAD, MY CAR LURCHES FORWARD WITH BRIEF SPURTS OF ACCELERATION. THIS HAS NOTHING TO DO WITH THE GAS PEDAL. IT SEEMS THAT OTHERS ARE HAVING SIMILAR ISSUES (HTTP://PRIUSCHAT.COM/FORUMS/GEN-III-2010-PRIUS-CARE-MAINTENANCE-TROUBLESHOOTING/72662-ACCELERATION-PROBLEM-OUR-2010-PRIUS-GEN-V-5.HTML#POST1052091). THIS COULD BE DANGEROUS, ESPECIALLY ON A WET ROAD. AND THE ROADS ARE SO TERRIBLE IN LOS ANGELES, THAT I EXPERIENCE THIS PROBLEM MORE OFTEN THAN I WOULD LIKE. HOPEFULLY ENOUGH PEOPLE REPORT THIS PROBLEM THAT TOYOTA TAKES ACTION. *TR

2010 TOYOTA PRIUS, I PICK UP THE CAR AT THE DEALER ON 20 NOV 2009. WHEN EVER I SET THE CRUISE CONTROL IT WORKS FINE UNTIL I TAP THE BRAKE TO TURN IT OFF. THE CAR SPEEDS UP. I HAVE TO PRESS HARDER ON THE BROKE TO GET THE CRUISE CONTROL TO DISENGAGE AND SLOW DOWN. ITS AS IF THE CRUISE CONTROL IS NOT SENSING THAT THE BRAKE WAS DEPRESSED AND RELEASING. I TOOK THE CAR BACK TO THE DEALER ON 12-20-2009 HAVING DRIVEN IT A MONTH AND HAVING A CHANCE TO GET A FEEL FOR THE CAR. THEY SAID NOTHING WAS WRONG THAT ALL THE CARS DID THIS. EVERY CAR I HAVE OWNED HAS HAD CRUISE CONTROL ON IT AND HAS NEVER ACTED THIS WAY. I ALSO DRIVE A RX350 LEXUS THAT DOES NOT HAVE HIS PROBLEM. *TR

I OWN A 2010 TOYOTA PRIUS THAT SEEM TO LOOSE BRAKING POWER WHEN I HAVE THE BRAKE PEDAL PRESSED DOWN AND THEN HIT A POTHOLE OR MANHOLE COVER. IT HAPPENS ALL THE TIME. WHEN I TOOK IT INTO THE DEALER A FEW MONTHS AGO THEY DIDN'T FIND A PROBLEM, BUT IT APPEARS TO BE A COMMON PROBLEM FOR THIS MODEL. *TR

WHILE ACCELERATING TO MAKE A RIGHT HAND TURN SIGNAL (SPEED APPX 30MPH) I DEPRESSED THE BRAKES TO SLOW THE VEHICLE DOWN TO A REASONABLE SPEED TO SAFELY MAKE THE TURN, THE CAR SLOWED, I BEGAN THE TURN BUT MID- TURN WITH MY FOOT STILL DEPRESSING THE BRAKE PEDAL THE CAR MADE A 1 ' 2 SECOND ACCELERATION. *TR

I NOTICED THAT THE CAR LURCHES FORWARD WHENEVER DRIVEN ON A MANHOLE, OR A ROUGH PATCH ON ROAD, OR A SPEED HUMP DESPITE THE BRAKING. THOUGH I REGAIN CONTROL WITHIN SECONDS, THE MOMENT OF LURCH IS SCARY AND MAKES ME FEEL UNSAFE IN OTHER TRAFFIC SITUATIONS. THIS HAPPENS AT ALMOST ALL SPEEDS. I GUESS FROM NOW ONWARDS I WILL MAINTAIN ENOUGH GAP BETWEEN THIS CAR AND THE FORWARD ONE AS I SEEM TO BE NOT ABLE TO TRUST THIS CAR ANY FURTHER. PERHAPS I WILL NEVER RECOMMEND THIS CAR OR ANY TOYOTA TO ANYONE IN FUTURE. *CN

WHEN THE CAR GOES OVER AN UNEVEN OR BUMPY [SURFACE,] OR DOWN AN INCLINE, THE CAR ACCELERATES OR LURCHES FORWARD. THIS HAS OCCURRED SEVERAL TIMES AND IS UNNERVING TO THE POINT I HAVE SWITCHED CARS WITH MY HUSBAND. ALSO, WHEN COMING OUT OF MY GARAGE MOST EACH DAY, THE CAR ROLLS BACK ON BATTERY POWER, BUT THE BRAKES ARE STIFF, JUST LIKED YOU WOULD PUMP THEM WHEN THE CAR IS OFF (REAL HARD) UNTIL THE CARS MOTOR TURNS ON. BUT BY THEN, YOU HAVE ROLLED 15 OR SO FEET BACKWARD WITH LITTLE TO NO BREAK CONTROL. THEY FEEL LIKE THEY WON'T STOP THE CAR. *TR

TL*THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHEN SLOWING DOWN AND MAKING A RIGHT TURN, THE VEHICLE ACCELERATED; HOWEVER, IT HAS NEVER OCCURRED WHEN HE MADE A LEFT TURN. HE WAS DRIVING APPROXIMATELY 10 MPH. THE FAILURE MILEAGE WAS 4000 AND THE CURRENT MILEAGE WAS 5000. UPDATED 03/12/10. *LJ UPDATED 09/21/10

TODAY AT AROUND 220- PRIUS JUMPED OR .. LURCHED FORWARD AS I WAS BRAKING - I THINK ON BUENA VISTA - FRONT OF ST JOES - I HAD COME FROM PARTNERS CREDIT UNION - WAS GOING TO FREEWAY 134 - I WAS GOING SLOW MAYBE 20 MPH - CARS WERE COMING TO STOP AT STOPLIGHT BEFORE FREEWAY ON RAMP - AS I BRAKED GENTLY I HIT A METAL COVER ON GROUND - BUT INSTEAD OF STOPPING THE CAR LURCHED FORWARD - FORTUNATELY - THERE WAS AMPLE ROOM IN FRONT OF ME- I WAS GOING SLOW AND BRAKED EARLY - OTHERWISE I MIGHT HAVE HIT THE STOPPED CAR IN FRONT - MORE THAN JUST SLIPPING - LIKE WHEN BRAKING ON ICE.. THE CAR ACTUALLY JERKED FORWARD - EARLIER IN WEEK - I WAS BACKING OUT OF DRIVEWAY AT HOUSE - AND AS I WAS BACKING UP AND BRAKING THE BRAKES WERE REAL JERKY - HARD - OVER - RESPONSIVE - THEN WHEN I HIT THE ROAD - GOING FORWARD - BRAKES WENT BACK TO NORMAL. *TR

WHILE COMING TO A STOP AT A RED LIGHT , I APPLIED MY BRAKES AND AT THE SAME TIME , WENT OVER A SMALL POT HOLE. IT SEEMED TO ME LIKE THE CAR SPED UP. IT ONLY HAPPENED FOR A SPLIT SECOND BUT THAT SECOND COULD MEAN THE DIFFERENCE BETWEEN HITTING SOMEONE AND MISSING. THIS HAS HAPPENED TWICE TO ME AND I DO THINK IT IS A VERY DANGEROUS SITUATION. I HAVE BEEN TOLD THIS IS BY DESIGN BUT IF IT IS ,IT IS A POOR DESIGN. *TR

I HAVE OWNED A 2010 PRIUS FOR ABOUT A MONTH, AND HAVE DRIVEN JUST OVER 1000 MILES ON IT. THERE HAVE BEEN THREE SEPARATE INCIDENTS NOW WHERE MY BRAKES HAVE EXPERIENCED A SUDDEN FAILURE WHILE DECELERATING. EACH TIME OCCURRED RIGHT AFTER HITTING A POTHOLE OR A BUMP IN THE ROAD. PASSENGERS IN MY CAR HAVE REPORTED A FEELING OF THE BRAKES "CATCHING" OR "JERKING" WHILE DRIVING ON BUMPY ROADS. THE THREE INCIDENTS I HAVE MENTIONED WERE DURING WINTER AND DURING POSSIBLY ICY CONDITIONS. HOWEVER, I KNOW HOW TO OPERATE A VEHICLE ON ICE, AND I AM AWARE OF HOW ABS BRAKING FEELS. DURING EACH INCIDENT, I WOULD BE BRAKING SLOWLY, WITH PLENTY OF TIME, THEN HIT A BUMP, AND EXPERIENCE A FEELING OF SKIDDING WHILE THE BRAKES DISENGAGED FOR A FEW SECONDS. I ALMOST HIT A PEDESTRIAN AT A TOLL BOOTH, A CONCRETE DIVIDER DURING HIGHWAY DRIVING, AND ANOTHER MOTORIST AT A SUDDEN STOP CONDITION ALONG ANOTHER HIGHWAY. PLEASE INVESTIGATE THESE CARS. I CAN COMPENSATE MY DRIVING SKILLS TO ADJUST FOR ROAD CONDITIONS THAT I AM AWARE OF. IF ANY SUDDEN BRAKING IS REQUIRED, AND I HIT A POTHOLE AT THE RIGHT TIME, I WILL NOT BE ABLE TO STOP. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. DURING BRAKE APPLICATION WHILE MAKING A LEFT TURN ONTO A GRAVEL ROAD , THE VEHICLE SURGED FORWARD. IDENTICAL FAILURES OCCURRED THREE TIMES. THE DEALER WAS CONTACTED AND THEY STATED THAT THEY DID NOT HAVE ANY REPORTS OF THE FAILURE. THE VEHICLE HAS NOT BEEN DIAGNOSED. THE FAILURE MILEAGE WAS 2800. THE CURRENT MILEAGE WAS 6000. UPDATED 01/29/10 *BF UPDATED 01/29/10.

I HAVE A 2010 TOYOTA PRIUS, WHEN I AM TRYING TO STOP AND HIT A POTHOLE, OR MANHOLE COVER OR THE STREETS ARE WET, THE CAR'S BRAKES WILL DISENGAGE TEMPORARILY. IT IS SCARY AND I'VE ALMOST HAD A FEW ACCIDENTS. PLEASE LOOK INTO THIS. *TR

I HAVE A 2010 PRIUS WHICH I BOUGHT IN AUGUST 2009. ON SEVERAL OCCASIONS, APPROXIMATELY 8-10 TIMES, I HAVE BEEN BRAKING AT SLOWER SPEEDS WHEN COMING TO AN INTERSECTION. WHEN I PUT MY FOOT ON THE BRAKE AND THE CAR HAPPENS TO HIT A BUMP OR HOLE IN THE ROAD AND THE CAR NOTICEABLY SURGES. MY FOOT IS NOT ON THE ACCELERATOR AND THIS HAS NOTHING TO DO WITH THE FLOOR MATS BECAUSE MY FLOOR MAT IS PINNED TO THE FLOOR OF THE CAR. THE MOST RECENT TIME THIS HAPPENED WAS 12/28/2009. *TR

TOYOTA PRIUS 2010: WHEN THE CAR HITS A BUMP IN THE ROAD IT WILL ACCELERATE SO FAST BY ITSELF WHICH CAN BE VERY DANGEROUS AND FATAL. IT CAN HIGHLY CAUSE AN ACCIDENT IF THE DRIVER CANNOT STEP ON THE BRAKES IN TIME TO STOP THE CAR ACCELERATION. I WENT TO MY LOCAL TOYOTA DEALER HERE IN QUEENS NEW YORK AND TO MY SURPRISE THE REP SAID" I HAVE NEVER HEARD OF THAT COMPLAINT" AND DID NOT PURSUE THE MATTER AT ALL. ANOTHER SAFETY CONCERN IS THAT I HIT A SMALL POTHOLE AND THE WHOLE TIRE WAS DAMAGED ON MY BRAND NEW 2010 PRIUS WHICH I HAVE BEEN DRIVING FOR BARELY TWO MONTHS. I AM VERY CONCERNED ABOUT THESE SAFETY PROBLEMS AND DO NOT REALLY KNOW WHERE TO START GETTING ASSISTANCE. THANK YOU VERY MUCH. *TR

I WAS DRIVING MY NEW 2010 PRIUS (APPROX. 250 MILES ON ODOMETER) WHEN APPROACHING A STOP LIGHT EARLIER TODAY WITH MY FOOT GENTLY APPLYING PRESSURE TO THE BRAKE WHEN SUDDENLY THE CAR SURGED FORWARD ACCELERATING. I AM CERTAIN MY FOOT WAS NOT ON THE ACCELERATOR PEDAL NOR WAS ANYTHING ON THE FLOOR AND THE FLOORMAT WAS APPROPRIATELY POSITIONED. THE ACCELERATION ONLY LASTED A SECOND, IE ONCE I APPLIED MORE PRESSURE SHARPLY TO THE BRAKE PEDAL THE CAR SLOWED AND THE ACCELERATION CEASED. THIS IS THE ONLY TIME THIS HAS OCCURRED. *TR

I BOUGHT A 2010 PRIUS IN SEPTEMBER 2009. IN OCTOBER, I DROVE OVER A POTHOLE THAT WAS ABOUT 6 INCHES DEEP AND COVERED THE ENTIRE WIDTH OF THE LANE. HERE IS WHAT IT FELT LIKE HAPPENED: WHEN THE BACK WHEELS HIT THE BOTTOM OR THE TOP OF THE POTHOLE, MY CAR SUDDENLY ACCELERATED AND I HAD A VERY DIFFICULT TIME STOPPING IT. I MANAGED TO NOT CRASH INTO THE CAR IN FRONT OF ME, BUT JUST BARELY. IT HASN'T HAPPENED SINCE. THE POTHOLE WAS APPARENTLY THE RESULT OF WORK ON THE ROAD, B/C IT WAS SQUARED, LIKE THE PAVEMENT HAD BE INTENTIONALLY CUT. *TR

2010 TOYOTA PRIUS ACCELERATES SLIGHTLY WHEN BRAKE IS COMPRESSED AND CAR IS TRAVELING OVER LARGE ROAD BUMPS OR MANHOLE COVERS/SLIPPERY SURFACES (MULTIPLE TIMES EACH TIME I DRIVE). I HAVE NOT YET REPORTED THIS TO TOYOTA, BASED ON THE ONLINE AND NEWS-BROADCAST ACCOUNTS OF HOW TOYOTA HAS RESPONDED TO MUCH MORE SERIOUS ACCELERATION ISSUES. I INTEND TO ATTEMPT RETURNING THE VEHICLE TO THE COMPANY FOR A FULL REFUND. *TR

I HAVE A 2010 TOYOTA PRIUS AND IT ACCELERATES RANDOMLY. USUALLY WHEN I PUSH ON THE BRAKE A LITTLE BIT, BUT NOT ALL THE WAY, IT WILL JUMP FORWARD AND ACCELERATE. I HEARD ABOUT THE ISSUES WITH THE MAT AND I REMOVED THE MAT MONTHS AGO. ITS IS STILL UNINTENTIONALLY ACCELERATING. IT HAS HAPPENED MAY 6 TIMES SINCE I BOUGHT THE CAR IN JULY. I AM SCARED TO DRIVE IT AND HAVE BEEN DRIVING MY SPARE CAR UNTIL SOMETHING IS DONE BY TOYOTA OR SOMEONE ELSE THAT CARES ABOUT THE SAFETY OF DRIVERS. *TR

WHILE APPLYING THE BRAKES TO SLOW DOWN OR TO COME TO A STOP, IF THE CAR HITS A BUMP, POTHOLE OR THE LIKE, THE BRAKES RELEASE MOMENTARILY, CAUSING THE CAR?S MOMENTUM TO CONTINUE FORWARD LONGER/FURTHER THAN YOU WOULD NORMALLY EXPECT OR WANT. THIS IS ESPECIALLY DANGEROUS WHEN COMING TO A STOP AT A NEW YORK CITY PEDESTRIAN CROSSWALK OR TRYING TO SLOW DOWN WITH A CAR CLOSE IN FRONT OF YOU. I BROUGHT THE CAR INTO THE DEALERSHIP AND HAD IT EVALUATED BY TOYOTA'S FIELD TECHNICAL SPECIALIST WHO REPORTED THE FOLLOWING, ""WHEN [THE CAR] SENSES IMPENDING WHEEL SLIP, IT WILL FIRST DISABLE THE REGENERATIVE BRAKES. WHEN IT DOES THAT IT FEELS LIKE THE CAR SORT OF ACCELERATES BECAUSE YOU LOST THE REGENERATIVE BRAKING AND YOU'RE USING THE BRAKE ASSIST THAT YOU HAVE FROM YOUR FOOT. SO THAT IS 'NORMAL OPERATION' ON THE SYSTEM. IT IS WORKING AS DESIGNED." DESPITE THE EXPLANATIONS FOR WHY THIS IS HAPPENING AND WHETHER OR NOT THIS IS ?NORMAL OPERATION?, THE BOTTOM LINE IS, IF THE CAR IS NOT STOPPING WHEN IT SHOULD, THE SAFETY OF PASSENGERS AND PEDESTRIANS IS IN JEOPARDY. I CALLED AND WROTE TWO CERTIFIED LETTERS TO TOYOTA'S CUSTOMER EXPERIENCE DEPARTMENT AND TO AKIO TOYOTA, AND RECEIVED A PHONE CALL FROM AN EXECUTIVE ANALYST FROM THE PRESIDENT'S OFFICE. NO TOYOTA REPRESENTATIVE WOULD DO ANYTHING IN REGARDS TO THE PROBLEM--THEY MAINTAIN THAT THE BRAKING OPERATION IS NORMAL. I HAVE SEEN OTHER COMPLAINTS ON THE NHTSA WEB SITE AND ON PRIUS OWNERS BLOGS THAT CONTRADICT TOYOTA'S ASSERTION AND SUPPORT THE CLAIM THAT THE BRAKES ARE INDEED A SAFETY ISSUE THAT MUST BE ADDRESSED.*TR

RE: 2010 PRIUS. WHEN BRAKING OVER A POTHOLE, THE CAR SURGED FORWARD SUDDENLY (SUDDEN ACCELERATION DESPITE BRAKING). *TR

MY NEW 2010 PRIUS ACCELERATED ON IT'S OWN AS I WAS BRAKING AND SLOWLY APPROACHING THE CAR IN FRONT OF ME THAT WAS STOPPED AT A STOP LIGHT QUITE SOME DISTANCE AWAY. MY CAR HAD ALMOST COME TO A COMPLETE STOP WHEN SUDDENLY THE ENGINE REVVED ON IT'S OWN AS MY FOOT WAS STILL ON THE BRAKE. I HAD TO PRESS DOWN SO HARD ON THE BREAK TO KEEP IT FROM SURGING FORWARD THAT THE ABS LIGHT CAME ON AND THEN THE CAR'S REV WENT DOWN ON IT'S OWN AND ALL WAS BACK TO NORMAL AND HADN'T HAPPENED AGAIN SINCE. I BROUGHT THE CAR TO THE DEALER AND THEY KEPT IT FOR TWO DAYS BUT DIDN'T FIND ANYTHING WRONG WITH IT. I HAVE TWO SMALL CHILDREN AND BOUGHT THIS CAR FOR A NUMBER OF REASONS, SAFETY BEING ONE OF THE IMPORTANT ONES. I AM NO LONGER FEELING SAFE. THIS WAS NOT THE FLOOR MATS, OR A SUDDEN STOP MISTAKING ONE PEDAL FOR ANOTHER, OR ANY OTHER FORM OF DRIVER ERROR. THIS WAS THE CAR! PLEASE HELP TO DISCOVER THE CAUSE AND MAKE TOYOTA FIX IT BEFORE SOMEONE GETS HURT OR KILLED. THANK YOU, CHRIS TOPPIN *TR
