2003 Toyota 4runner Transmission Problems

Your 4Runner's frame has experienced severe corrosion throughout, which has caused structural damage to the frame itself. This is a serious structural issue that will require professional inspection and repair.

The frame of the car has been rusting at a significant rate in the last 4 years. Mechanic identified major rust issues that would make the vehicle not safe in case of an accident.

THERE IS EXCESSIVE RUST ON THE UNDERBODY OF MY 2003 4RUNNER. IT HAS JUST 165,000 MILES AND THE FRAME IS EXTREMELY RUSTED. BEING ONLY 15 YEARS OLD I FIND THIS TO BE VERY SAD AND UNREASONABLE. THE CAR SHOULD BE ABLE TO LAST 20-30 YEARS AND 300,000 MILES. THE CAR HAS BEEN REGULARLY WASHED AND DRIVEN IN PENNSYLVANIA, ILLINOIS, OHIO, NEW YORK. IF THERE WAS ADDITIONAL TREATMENT REQUIRED FOR THE FRAME IT SHOULD HAVE BEEN COATED, OR AT THE VERY LEAST NOTIFY THE CUSTOMERS TO MAKE SURE THEY DO IT. THESE CAR SHOULD LAST MUCH MUCH LONGER AND AS EXPENSIVE AS THE 4RUNNERS ARE THEY SHOULD LAST.

EXTENSIVE FRAME RUST THROUGH AND REAR DIFFERENTIAL/AXLE RUST THE FRAME RUST IS IN AN AREA THAT CONNECTS THE REAR AXLE TO THE VEHICLE.

MY 2003 TOYOTA HAD EMISSIONS ISSUES IN THAT ALL FOUR OXYGEN SENSORS WOULD FAIL QUICKLY. IT TOOK ME TWO YEARS AND LOTS OF MONEY LATER TO DETERMINE THAT THE CAUSE OF THIS IS BECAUSE TRANSMISSION FLUID IS WICKING ITS WAY THROUGH THE TRANSMISSION SOLENOID HARNESS ALL THE WAY TO THE ECU AND ONCE THERE BECAUSE OF THE WAY THE ECU IS MOUNTED GETS INTO ALL OF THE OTHER WIRING HARNESSES OF JUST ABOUT EVERY OTHER SENSOR. I WENT TO TOYOTA AND THE FIRST TECHNICIAN NEVER HEARD THAT HAPPENING BEFORE BUT ANOTHER OVERHEARD OUR CONVERSATION AND SAID "I BET YOU HAVE A 4RUNNER" SO YEAH ITS HAPPENED TO OTHERS. THEY WANTED NEARLY $4500 TO FIX THE ISSUE. NEW ENGINE WIRING HARNESS $1500-$2000 AND ANOTHER $1000 FOR THE LABOR AND THE REST OF THE ESTIMATE IS FOR OTHER PARTS NOT SPECIFIED. THEIR SOLUTION IS TO CUT THE WIRE BELOW THE TRANSMISSION WIRING HARNESS CONNECTOR THEN SPLICE AND SOLDER BUT I WOULD HAVE TO REPLACE NEARLY ALL THE CRITICAL WIRING IN THAT CAR. I CANT GIVE AN EXACT DATE ON WHEN IT STARTED GOING WRONG BUT I CAN LOOK AT THE SERVICE HISTORY ON THE TOYOTA OWNER'S WEBSITE AND GIVE YOU THIS TIMELINE. 0-89,997 - NO, ISSUES WITH EMISSIONS OR ELECTRICAL SYSTEMS. 89,997MI - 90K SERVICE DONE - TRANSMISSION FLUID CHANGE W/FLUSH DONE AT DEALER. 98,152MI - CAR REPORTING LEAN CODES, DEALER REPLACES MAF SENSOR. 100,117 - CAR REPORTING LEAN CODES, DEALER REPLACES O2 SENSOR AND A/F SENSOR BANK 2 POSITION 1 & 2 105,312 - CAR REPORTING LEAN CODES, DEALER REPLACES BANK 1 POSITION 1 A/F SENSOR AND MAF SENSOR AGAIN. TOTAL COST $798.76. THERE ARE MORE BUT I HAVE CHARACTER LIMITS. I WILL SAY THIS THOUGH THAT THE PROBLEM SHOULD HAVE BEEN OBVIOUS BECAUSE YOU CAN CLEARLY SEE THE FLUID WHEN YOU UNPLUG THE O2 SENSOR FROM THE HARNESS BUT TOYOTA WAS CONTENT CHARGING ME $500-$700 EVERY 10K MILES WITHOUT ACTUALLY FIXING IT. CAR STILL REMAINED FUNCTIONAL BUT RUINED FUEL ECONOMY.

VEHICLE HAS A LOW GEAR SOUND WHICH BEGAN WHEN VEHICLE WAS RELATIVELY NEW AS I TRAVELLED DOWN SLIGHT GRADES. I NEVER COMPLAINED BECAUSE THAT WAS THE ONLY TIME IT SEEMED ABNORMAL AND THERE ARE ONLY A VERY PLACES IN MY TOWN WHERE THE HILL WAS STEEP ENOUGH TO CAUSE IT. PLUS I ASSUMED IT WAS RELATED TO THE TRAC BRAKING SYSTEM AND MIGHT BE NORMAL. LAST WEEKEND ON A 5 HOUR TRIP EACH WAY THE PROBLEM BEGAN TO MANIFEST ITSELF AS I ACCELLERATED ON FLAT GROUND. THE TACHOMETER SHOWED LOW RPMS (UNDER 2000) UNTIL 50-60 MPH. HOWEVER THE SOUND WAS MUCH MORE NOTICIBLE WITH SOME ADDITIONAL VIBRATION. THE VIBRATION IS NOW WORSE, COULD IT BE A SPEED SENSOR PROBLEM?

TL* THE CONTACT OWNS A 2003 TOYOTA 4 RUNNER. THE CONTACT WAS DRIVING 55 MPH WHEN THE TRANSFER CASE IMPLODED AND SPEWED OUT FROM UNDER THE VEHICLE, DAMAGING THE DRIVELINE. THE VEHICLE WAS THEN TOWED TO A LOCAL MECHANIC SHOP. THE MECHANIC REPLACED THE VEHICLE WITH A USED TRANSFER CASE AND DRIVELINE AT A COST OF $1,374. THE MANUFACTURER WAS CONTACTED AND A CASE WAS FILED. NO OTHER ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 152,664. UPDATED 06/16/11*LJ THE CONSUMER HAS SINCE TRADED THE VEHICLE. UPDATED 10/12/11

MY 4RUNNER HAS BEEN MAKING AN AWFUL CLUNKING NOISE COMING FROM THE REAR FOR ABOUT 2 YEARS NOW. I HAVE DONE SOME RESEARCH AND IT SEEMS TO HAVE HAPPENED IN THE LEXUS GX470 AS WELL. THE 03-06 4RUNNERS HAVE THE SAME DRIVELINE AS THE LEXUS AND UNLIKE LEXUS, TOYOTA HAS REFUSED TO FIX THIS PROBLEM. PLEASE HELP! *TR

FROM A COMPLETELY STOPPED POSITION, LETTING OFF THE GAS AND ALLOWING THE TRUCK TO IDLE FORWARD RESULTS IN A KLUNK NOISE WHETHER YOU ACCELERATE OR NOT. AS I HAVE READ, IT IS A PROBLEM WITHIN THE DRIVETRAIN. I TOOK THE TRUCK TO TOYOTA TO HAVE IT LOOKED AT. THEY SAY IT IS BECAUSE THE REAR NEEDS TO BE LUBED WITH EVERY OIL CHANGE AND WAS COMPLETELY DRY. THEY LUBED IT UP AND SAID THE PROBLEM SHOULD IMPROVE WITH TIME. THE TRUCK IS STILL MAKING THE KLUNK NOISE. THE TRUCK HAS ONLY 85K. THIS SEEMS VERY SIMILAR TO THE PROBLEM WITH TOYOTA TUNDRA AND SOME LEXUSES. *TR

2003 TOYOTA 4RUNNER WAS STUCK IN 4-LO, VEHICLE UNABLE TO TRAVEL AT SAFE HIGHWAY SPEEDS. PART THAT NEEDS REPLACED IS TRANSFER CASE ACTUATOR. *TR

REAR MAIN SEAL LEAK, LARGE AMOUNT. *TR

TL*THE CONTACT OWNS A 2003 TOYOTA 4RUNNER. WHILE DRIVING 2 MPH WITH THE BRAKES APPLIED, THE VEHICLE WOULD SURGE AND MAKE A THUMPING SOUND. THE DEALER LUBRICATED THE U JOINT, BUT THE FAILURE RECURRED A MONTH LATER. THE FAILURE MILEAGE WAS 2,000 AND CURRENT MILEAGE WAS 70,000. UPDATED 03/04/08. *LJ THE CONSUMER STATED A PROPELLER ASSEMBLY/DRIVESHAFT WAS NEEDED TO CORRECT THE PROBLEM. UPDATED

CONTINUING PROBLEM ON MY 2003 V8 4RUNNER WITH THE DRIVE SHAFT. WHEN I COME TO A STOP OR WHEN I ACCELERATE AFTER A STOP THERE IS A MOMENTARY LAG THAT FEELS LIKE A "CLUNK" OR THAT SOMEONE HAS JUST RUN INTO YOUR BACK BUMPER. TOYOTA DEALER "FIXES" THE PROBLEM WITH GREASE TO THE SLIP YOKE BUT AFTER 2,000 MILES IT COMES BACK AND IS ONLY GETTING WORSE. I'VE COMPLAINED TO THE DEALER CONTINUALLY AND LEXUS 470 (SAME VEHICLE) HAS A TSB ON THE SAME OCCURRENCE. IT HAS BECOME INCREASINGLY ANNOYING AND CAN ONLY BE CLASSIFIES AS A DANGEROUS DEFECT. *TR

I HAVE A 2003 4RUNNER THAT HAS A HORRIBLE CLUNKING SOUND THAT HAPPENS AT RANDOM. THE TOYOTA DEALER HAS ATTEMPTED TO FIX IT 3 TIMES. IT WILL HAPPEN WHEN COMING TO A STOP OR STARTING FROM A STOP. IT'S VERY ANNOYING AND NOT VERY COMFORTING. IF THE DRIVESHAFT IS SLAMMING AND MAKING THIS NOISE, I CAN'T IMAGING ANYONE THINKING THAT IS VERY SAFE. THE THING COULD BREAK AT ANY MOMENT. WHO KNOWS WHAT DAMAGE THE SLAMMING DOES TO IT! TOYOTA NEEDS TO FIX THIS BEFORE SOME GETS HURT FROM IT. *TR

MY 2003 TOYOTA 4RUNNER MAKES A CLUNK SOUND THAT IS FELT THROUGHOUT THE VEHICLE WHEN COMING TO A STOP OR WHEN BEGINNING TO TAKE OFF. THIS WAS FIRST NOTICED AT APPROXIMATELY 40,000 MILES. PER THE TOYOTA DEALERSHIP, REMOVING THE DRIVESHAFT AND GREASING THE SPLINE YOKE QUIETS THE CLUNK FOR APPROXIMATELY 20,000 MILES. THIS IS PARTLY TRUE, AS THE GREASING QUIETS IT, BUT IT DOES NOT GO AWAY AND THE CLUNK GET STRONGER EVERY DAY THE CAR IS DRIVEN UNTIL YOU FEEL LIKE YOU ARE BEING REAR ENDED. TOYOTA STATES THIS IS NORMAL FOR THE OPERATION OF THE VEHICLE. IT IS NOT NORMAL, AND IT IS ABSURD TO THINK IT IS NORMAL. THE CAR SHOULD ACCELERATE FROM A STOP WITHOUT A CLUNK AND COME TO A STOP WITHOUT A CLUNK. THIS PROBLEM IS WIDELY DOCUMENTED, BUT TOYOTA HAS YET TO PROVIDE A FIX. THE "CLUNKING" CHANGES YOUR DRIVING BEHAVIOR/HABITS IN ORDER TO MINIMIZE THE CLUNK, BUT IN THE END, THE CAR CLUNKS WHEN TAKING OFF, AND CLUNKS WHEN COMING TO A STOP. THE TOYOTA DEALERSHIP STATES NO DAMAGE IS BEING INCURRED TO THE VEHICLE BY THE CLUNKING, THIS MAY BE TRUE, BUT YOU CERTAINLY DO NOT FEEL SAFE AND SECURE WHEN THE VEHICLE CLUNKS AND SHAKES THE CAR AT VIRTUALLY EVERY STOP AND START. TOYOTA NEEDS TO FIND A FIX TO ENSURE TOYOTA CUSTOMERS ARE SAFE WHEN THEY DRIVE, FEEL SAFE WHEN THEY DRIVE, AND ARE SATISFIED WITH THE TOYOTA VEHICLE THEY DRIVE. *TR

WHEN COMING TO A STOP AND/OR ACCELERATING FROM A STOP THE CAR WILL JERK FORWARD WITH A THUD. SOMETIMES TWO OR THREE THUDS ARE FELT AND HEARD. THE DEALER WITNESSED THIS PROBLEM AND OURISMAN TOYOTA IN CHANTILLY, VA REPLACED THE TRANSMISSION AT 14,500 MILES. THE PROBLEM SEEMED TO GO AWAY FOR A WHILE. I RETURNED TO THE SAME DEALER WITH THE SAME COMPLAINT AT 32,000 MILES AND THEY REPLACED THE DRIVE SHAFT. I RETURNED AGAIN ON 11/30/04 AND THE SERVICE MANAGER WITNESSED THE SAME PROBLEM WITHIN 200 FEET OF DRIVING. THE SERVICE MANAGER INDICATED HE BELIEVES THIS IS NORMAL (EVEN THOUGH THIS WAS NOT A PROBLEM TILL ABOUT 12,000 MILES). HE IS GOING TO DISCUSS THIS WITH THE TOYOTA REP WHO IS IN TOWN THIS WEEK.*AK I

FROM THE DATE OF PURCHASE THERED HAS BEEN A LOUD "THUD" NOISE WHEN RELEASING THE BRAKE PEDAL. THIS DOES NOT OCCUR ON A CONTINUAL OR PREDICTABLE BASIS. THE TOYOTA DEALERSHIP EXAMINED THE 4RUNNER AND DIDN'T FIND THE BRAKES TO BE FAULTY; HOWEVER THE SOUND AND A SURGE ARE STILL PRESENT IT REMINDS ME OF THE "THUD" SOUND THAT WAS INHERENT IN THE T-100 PICK-UP TRUCK WHEN IT WAS STARTED IN REVERSE. I HAVE AN AUTOMATIC TRANSMISSION IN MY VEHICLE AND WONDER IF FAILURE IS IMMINENT THERE OR IN THE DRIVE SHAFT. IN EITHER CASE THIS IS AN OBVIOUS FLAW AND MUST BE ADDRESSED BY TOYOTA. MY DAUGHTER OWNED A 2002 TOYOTA PICK-UP TRUCK AND SAID IT MADE THE SAME SOUND FOR AS LONG AS SHE OWNED IT. *AK

WHEN COMING TO A STOP OR EVEN WHEN STOPPED, A LOUD THUD IS HEARD AND FELT AS IF TORQUE CONVERTER IS STILL DOWN SHIFTING. WHEN BRAKES RELEASED, THUD IS HEARD AND FELT AGAIN AS CAR ACCELERATES. DEALER SAYS BRAKES ARE FINE! I'M CONCERNED AS THIS IS NOT A NORMAL SOUND AND RECENTLY CAR ACTUALLY FELT LIKE IT WANTED TO MOVE FORWARD AS THUD WAS FELT AND HEARD. (THIS IS UNRELATED TO THE CAR WANTED TO LURCH FORWARD AT STOP WHEN A/C IS ON!)*JB

VIBRATION IN STEERING, MOST PREVALENT AROUND 70 MPH. STARTED AT 15,000 MILES. REBALANCED TIRES 3 TIMES AND DEALER DETERMINED THAT OEM TIRES WERE BAD. TRIED NEW TIRES AND THE PROBLEM PERSISTS. BELIEVED TO BE SAME AS LEXUS GX 470 PROBLEM WITH TSB FIX ST004-04. NO TOYOTA TSB YET. *JB

GATED SHIFTER, ON 2003 TOYOTA 4 RUNNER, ALLOWS YOU TO SHIFT THE VEHICLE PAST NEUTRAL (INTO REVERSE OR EVEN PARK) WHILE DRIVING, WITH OUT DEPRESSING THE BRAKE PEDAL. IF YOU PUSH STRAIGHT UP ON THE SHIFTER IT LOCKS IT OUT (AGAINST THE STAGGERED PLASTIC OF THE GATED SHIFTER). BUT IF YOU ACCIDENTALLY HIT THE SHIFTER ON AN ANGLE, IT CAN SLIDE PAST NEUTRAL AND INTO REVERSE OR EVEN PARK!*AK

VIBRATION IN STEERING WHEEL ,FLOORBOARDS, DRIVELINE AND DRONING NOISE. THIS IS AN UPDATE TO ID# 10060725. LEXUS OF TOYOTA HAS ANNOUNCED A TSB FOR THE GX 470 WHICH HAS THE SAME MECHANICALS AS THE TOYOTA 4RUNNER. THIS TSB ADDRESSES THE INDICATED PROBLEM THAT IS IN BOTH VEHICLES. IT IS :"STEERING ST004-04" "STEERING VIBRATION AND DRIVELINE VIBRATION/DRONE". UNFORTUNATELY THE FIX CAN ONLY BE APPLIED TO THE LEXUS VEHICLES PER DEALER.*AK

DRIVETRAIN VIBRATION FELT IN STEERING COLUMN AND FLOORBOARDS AT APPROX 1200RPM TO 2000RPM. THIS IS NOT TO BE CONFUSED WITH WHEEL SHIMMEY DUE TO TIRE OR WHEEL IMBALANCE. SERVICE DEALER INDICATES THIS IS NORMAL AND WILL RESOLVE ITSELF WITH MORE MILEAGE. *AK

2003 TOYOTA LIMITED 4-RUNNER V8- AWDFRONT-END VIBRATION PROBLEM FIRST PRESENTED THE VIBRATION PROBLEM AT 5048 MILES TO MY DEALER THE LAST WEEK OF AUGUST! IT IS MOSTLY FELT THROUGH THE STEERING WHEEL AND THE ACCELERATOR AND OCCURS AT VARIOUS SPEEDS. THERE IS ALSO A DRONING NOISE ASSOCIATED WITH THE VIBRATION AND IS MOST NOTABLE UNDER LOAD. THEY TRIED BALANCING THE WHEELS WITH NO IMPROVEMENT. THEY AGREED THE PROBLEM WAS THERE AND NOTIFIED CORPORATE. THEIR TECHNICAL STAFF HAD THEM REMOVE THE FRONT AXELS AND RETEST. THE VIBRATION, WHICH STARTED AT 22 MPH, WENT TO 32MPH 42, 55, AND 62MPH NOW DISAPPEARED! THE DEALER WAS ADVISED THAT THERE WAS AN ANGLE PROBLEM WITH THE FRONT DRIVE SHAFT. A WEEK LATER A TECHNICAL REPRESENTATIVE MET WITH ME AND MENTIONED THAT SEVERAL SIMILAR VEHICLES IN PHOENIX HAD THE SAME PROBLEM. HE SUGGESTED IT PROBABLY WOULD TAKE ABOUT TWO MONTHS TO GET A FIX. HE FELT THAT TOYOTA WOULD PROBABLY JUST REPLACE THE WHOLE UNIT RATHER THAN PUTTING IN DIFFERENT PARTS. TWO MONTHS LATER I TALKED TO THE TECH. REP. AGAIN AND HE MENTIONED THAT THE ENGINEERING GROUP HAD DETERMINED THE PROBLEM TO BE INTERFERENCES IN THE SPIDER GEAR ASSEMBLY IN THE FRONT DIFFERENTIAL, THEY WERE TRYING TO CORRECT THE CONDITION WITH THRUST WASHER SHIMS AND OTHER THINGS. THEY CLAIMED THAT THE PROBLEM WAS NOT A SAFETY FACTOR; I WONDER THOUGH WHAT WOULD HAPPEN IF THE FRONT END WERE TO FREEZE-UP SINCE ITS IN 4WD ALL THE TIME! I HAVE PRESENTED MY CLAIM TO THE TOYOTA CUSTOMER SUPPORT GROUP. I HAVE CALLED THEM REGULARLY ONCE A MONTH AND HAVE HAD NO SUCCESS AT FINDING WHAT THEIR SCHEDULE IS FOR THE FIX, --ONLY TO SAY WE ARE WORKING ON IT AND YOUR DEALER WILL NOTIFY YOU. IVE SINCE HEARD FROM MY DEALER STAFF THAT THEY HAVE A NUMBER OF LEXUS GX470'S AS WELL AS 2004S 4-RUNNERS INVOLVED. IM BEGINNING TO FEEL THAT THEY HAVE SO MANY VEHICLES INVOLVED IT MIGHT BE A LONG TIME BEFORE WE SEE A FIX! I HAUL A POP-UP TRAILER AND DOES IT MAGNIFY THE PROBLEM! *AK

2003 4 RUNNER. BOUGHT 8/1/03 WITH 63 ACTUAL MILES. 1ST OWNER. VEHICLE VIBRATES AT 75 MPH AND BECOMES SEVERE RUMBLE AT 80 TO 83 MPH. DEALERSHIP EXPLAINED THE PROBLEM AS THE TIRES. TIRES RE MOUNTED. RUMBLE STILL EXISTS. TIRES THEN REPLACED. RUMBLE STILL EXISTS. I CALLED TOYOTA CUSTOMER SERVICE HOT LINE, RECEIVED CLAIM # 2003-1212 0940, WHICH HAPPENS TO BE THE ACTUAL DATE AND TIME OF CALL ALSO. I AM STILL IN WAIT FOR A SOLUTION TO THIS PROBLEM THAT TOYOTA ACKNOWLEDGED HAS BEEN HAPPENING WITH SEVERAL 4 RUNNERS. PLEASE HELP. WAYDE *CB

VIBRATION IN DRIVETRAIN OF 2003 4RUNNER (AWD-V8). I DO NOT SEE MY ORIGINAL COMPLAINT LISTED IN THE NHTSA COMPLAINTS,SUBMITTED OCTOBER 2003. I AM WRITING TO LET ALL CONSUMERS KNOW THAT TOYOTA USA WAS FORCED TO BUY BACK MY 4RUNNER ON NOV 4TH 2003 THRU THE NEW VEHICLE LEMON LAW IN FLORIDA,(DUE TO THIS DRIVETRIAN VIBRATION).*AK

THERE IS A WHINING NOISE COMMING FROM THE FRONT DIFFERENTIAL AT ALL SPEEDS, BUT NOTICEABLE MOSTLY AT 80 MPH AND HIOGHER. TOYOTA AKNOWLEDGED, BUT REFUSES TO REPAIR.*AK ALSO DRIVERS SEAT IS LOOSE AND COMES OUT OF PLACE DURING EMERGENCY STOPPING. AGAIN TOYOTA IS AWARE, BUT REFUSES TO CORRECT.

2003 TOYOTA 4RUNNER V8/AWD W/ UNDER 5,000 MILES AT HIGHWAY SPEEDS THERE IS A VIBRATION AND LOW FREQUENCY "ROARING" NOISE THAT APPEARS TO COME FROM THE FROM AXLE/DIFFERENTIAL. SOUND CEASES WHEN COASTING. NOISE AND VIBRATION WAS NOTICED WITHIN FIRST 500 MILES OF OWNERSHIP AND IS INCREASINGLY GETTING WORST. THOUGHT TO BE TIRES WHICH WERE ROTATED AND DID NOT SOLVE PROBLEM. DEALER ANALYZED AND STATED THIS IS A NORMAL WORKING NOISE FROM THE DIFFERENTIAL WHICH HAS ALUMINUM PARTS. NOISE IS GETTING LOUDER. CONCERN THERE IS A DEFECT AND SAFETY ISSUE.*AK

WHILE DRIVING CAN SHIFT INTO REVERSE WITHOUT APPLYING PRESSURE TO THE BRAKE PEDAL. VEHICLE WAS TAKEN TO THE DEALER. DEALER STATED THA VEHICLE HAS A GATED SHIFTER, AND IT WAS NORMAL FOR THAT TO HAPPEN. CONSUMER CONCERNED THAT THERE WAS NO LOCKING FEATURE ON THE SHIFTER. *AK

MY WIFE WAS DRIVING HER 2003 TOYOTA 4RUNNER LIMITED,V8 WHEN THE TRANSMISSION POPPED OUT OF GEAR.SHE HAD IT IN 4D GEAR FOR NORMAL DRIVING.SHE PULLED OVER AND PUT IT IN 4D GEAR AGAIN AND IT POPPED OUT A SECOND TIME.THE CHECK ENGINE LIGHT ALSO APPEARED. SHE PULLED OVER AGAIN AND TURNED OFF THE AIR CONDITIONER AND SHE PROCEEDED TO DRIVE TO HER DESTINATION WITHOUT THE GEAR POPPING OUT.SHE CALLED OUR SON TO PICK UP THE CAR TO TAKE IT TO THE DEALER FOR SERVICE.THEY FOUND NOTHING WRONG WITH THE VEHICLE. THEY SAID IT HAD TO HAPPEN WHILE THEY WERE TESTING THE CAR TO FIX THE PROBLEM BUT THEY COULDN'T REPEAT THE SAME THING THAT HAPPENED WHEN MY WIFE WAS DRIVING IT. THIS SITUATION COULD BE POTENTIALLY DANGEROUS.WHERE DO WE GO FROM HERE,WHO DO WE CONTACT? MY WIFE'S WORK NUMBER IS 412-875-1481

CAR STALLS (GAS PEDAL DOES NOT RESPOND) WHEN TURNING INTO TRAFFIC. ALSO WHEN SLOWING TO A LOW SPEED AND THEN ACCELERATING. THIS HAS CAUSED US TO ALMOST BE HIT SEVERAL TIMES IN THE SIDE AND IN THE REAR. MOST OF THE TIME WHEN THIS HAPPENS THE CAR WITH TIRE MARKS LIGHT ON THE INSTRUMENT PANEL COMES ON AND FLASHES. THERE IS NO WAY TO PREDICT WHEN THIS SUDDEN LOSS OF THE ACCELERATOR WILL HAPPEN. IT IS VERY DANGEROUS. THIS HAPPENS AT LEAST ONCE ALMOST EVERY TIME WE DRIVE. ALSO SOMETIMES WHEN YOU START THE CAR AND BEGIN TO GO YOU HEAR DINGING SOUNDS AND FEEL AND HEAR BUMPS AND GRINDING NOISES. 2 LIGHTS COME ON IN THE INSTRUMENT PANEL WHEN THIS HAPPENS. 1 READS VSC TRAC AND THE OTHER READS TRAC OFF. IF YOU STOP AND RESTART THE ENGINE IT WILL EVENTUALLY STOP DOING IT. SOMETIMES THIS IS AFTER 1 RESTART AND SOMETIMES IT HAS TAKEN 5 AND 6. ON DAY IT WOULD NOT STOP NO MATTER HOW MANY TIMES YOU RESTARTED AND WE HAD TO DRIVE WITH LIGHTS ON. THIS HAS HAPPENED ABOUT 10 DIFFERENT TIMES.

THE GEAR SHIFTER WAS ABLE TO GO FROM NEUTRAL TO REVERSE. PH WHILE DRIVING FROM 0-45 MPH, THE SHIFTER WAS IN THE FOURTH GEAR, AND HAD SHIFTED TO DRIVE. THE CONSUMER ACCIDENT'S PUSHED THE SHIFTER TO PARK WHILE THE VEHICLE WAS IN MOTION. THE CONSUMER FELT THAT MOST VEHICLE'S HAVE A SHIFT LOCK BETWEEN NEUTRAL AND REVERSE WHEN THE VEHICLE IS MOTION. SCC
