TOYOTA SIENNA 2010 MINIVAN ENGINE STALLS WHILE DRIVING. WHEN DRIVING ON HIGHWAY OR ON CITY ROADS, ENGINE STALLS AND LOOSES ENGINE POWER FOR A FEW SECONDS (SEEMINGLY HAPPENS WHEN SHIFTING GEARS) WHEN ACCELERATED OR DECELERATED. THE ENGINE BASICALLY STALLS DURING DRIVING AND MAY LEAD TO SUDDEN VEHICLE SLOWNESS IN MIDDLE OF TRAFFIC. THE SUSPECTED PROBLEM ADVISED BY TOYOTA IS WITH TRANSMISSION AND THE ORIGINAL COST ESTIMATE WAS $5100 TO FIX THAT. LATER AFTER DISCUSSING WITH TOYOTA IT WAS LOWERED TO $3800 (APPROX) AND TOYOTA WARRANTY SUPPORT WAS READY TO PAY (ABSORB) $2000 AND $1800 TO BE PAID BY THE CUSTOMER. EVEN AFTER INITIAL REPAIR AND PAYMENT OF ($1800+TAX) $2166 THE VEHICLE STILL HAVE THE SAME SYMPTOMS AND ISSUES. PRESENTLY THE VEHICLE IS UNDER REPAIR WITH THE DEALER (FREMONT TOYOTA, CA). THE VEHICLE USE WAS NORMAL, REGULAR CITY/HIGHWAY USAGE, WELL MAINTAINED SINGLE OWNER. NOTHING HEAVY WAS TOWED AND USED IN ROUGH OR ABNORMAL CONDITIONS. IF POSSIBLE NTSB NEEDS TO: 1.

2010 TOYOTA SIENNA WAS STOPPED AT A RED LIGHT, WITH MY RIGHT FOOT ON THE BRAKE, WHEN IT SUDDENLY LAUNCHED ITSELF INTO THE BACK OF THE VEHICLE IN FRONT OF ME. (THIS WAS ALMOST UNBELIEVABLE, BUT THANK GOD I HAD A WITNESS! A GENTLEMAN PREVIOUSLY UNKNOWN TO ME, WHO JUST HAPPENED TO BE STANDING ON THE SIDE WALK WHEN HE SAW IT HAPPEN. AS I STEPPED OUT OF MY VEHICLE, I HEARD HIM DESCRIBING TO THE DRIVER IN FRONT OF ME WHAT I HAD JUST EXPERIENCED.)

TOYOTA SIENNA UNCONTROLLED ACCELERATION. I ATTEMPTED TO SLOW VEHICLE BY PUMPING BRAKES WHICH RENDERED THEM TEMPORARILY USELESS. SHIFTING INTO NEUTRAL DIDN'T WORK. THEN ACCELERATION NORMALIZED AND BRAKES REGAINED FUNCTION. *TR

IN THE QFC PARKING LOT, AT AROUND 5PM ON A CLEAR MONDAY EVENING I WENT TO TURN LEFT INTO A PARKING SPOT. I STEPPED ON THE GAS AND NOTHING HAPPENED, I LET UP A BIT AND STEPPED AGAIN AND MY 2010 TOYOTA SIENNA SHOT FORWARD. I SLAMMED ON THE BRAKE HALFWAY INTO THE PARKING SPOT AND RAN INTO THE TREE IN FRONT OF THE VAN. I LOOKED DOWN AND COULD SEE THE OUTLINE OF THE GAS PEDAL SO MY FOOT WAS DEFINITELY ON THE BRAKE. I WAS VERY SHAKEN UP. THE VANS BUMPER AND HOOD ARE DAMAGED AND THE TREE LOST SOME BARK. I HAD IT TOWED TO THE TOYOTA DEALERSHIP AND TOYOTA IS HAVING IT INVESTIGATED. IT HAS BEEN THERE FOR A MONTH NOW. POLICE WERE CALLED, BUT DID NOT TAKE A REPORT AS THERE WERE NO INJURIES. *TR

THIS HAPPEN ON MAY 3, 2010 AROUND 9:50AM . MY WIFE , BY HERSELF, DRIVE TO THE PARKING PLAZA IN FRONT OF RETAIL STORE, BEFORE IT HAPPENS SHE HAS FULLY BRAKE AND STOP , AND WAITING FOR OTHER DRIVER TO FULL OUT OF PARKING SPACE. SHE SLOWLY MAKES RIGHT TURN TO PARKING SPACE, THE CAR, SIENNA 2010 VAN, SUDDENLY ACCELERATES TO HIGH SPEED AND SMASHES TO THE FRONT STORE, CAUSING THE DAMAGE THE WHOLE FRONT STORE , LUCKILY NO BODY INJURY IN THE INCIDENT. I THINK SOMETHING UNUSUAL HAPPEN TO THIS CAR, I HAD CONTACTED TOYOTA TO FURTHER ANALYSIS OF THE CAR, RIGHT NOW THE CAR IS IN DEALERSHIP , AWAITING FOR REPAIR. *TR

TL* THE CONTACT OWNS A 2010 TOYOTA SIENNA. WHILE DRIVING AT SPEEDS OF 10 MPH, THE VEHICLE ABNORMALLY ACCELERATED WITHOUT WARRANT AND CRASHED. THE POLICE ARRIVED ON THE SCENE AND FILED A POLICE REPORT ACCORDINGLY. THERE WAS ONE REPORTED INJURY AND THE VEHICLE WAS DESTROYED. THE FAILURE AND CURRENT MILEAGES WERE 5,100.

INVOLUNTARY ACCELERATION. THE FAILURE HAPPENED WITHIN THE FIRST 30 MILES THAT WE HAD POSSESSION OF THE VEHICLE. THERE WAS ONLY 430 MILES ON THE VEHICLE. THE VEHICLE IS CURRENTLY AT TOYOTA BODY SHOP AND WE ARE AWAITING DISPOSITION OF THE VEHICLE. *TR

WHEN CAR IS STARTED EVEN IN WARM WEATHER, ENGINE RACES AND CAN GET UP TO 30 MILES PER HOUR WITHOUT DEPRESSING ACCELERATOR. SOMETIMES TAKES 15 TO 20 MINUTES TO GET TO A NORMAL IDLE. *TR

MY 2009 TOYOTA SIENNA ACCELERATED UNEXPECTEDLY AFTER THE CRUISE CONTROL WAS SET. THIS HAPPENED 2 DIFFERENT TIMES WHILE MY WIFE WAS DRIVING IT. I WAS NOT IN THE CAR. MY WIFE HAD TO IMMEDIATELY PRESS THE BRAKE PEDAL TO RELEASE THE AUTO CRUISE. AFTER THE BRAKE WAS PRESSED THE AUTOCRUISE RELEASED THE ACCELERATION. OUR CAR IS NOT IN THE RECALL LIST I THINK. WE NEVER TOOK OUR CAR FOR THE RECALL REPAIR AT ANY TIME SINCE WE HAVE HAD IT. *TR

I RECENTLY DROVE A RENTED 2010 TOYOTA SIENNA VAN, FROM ALAMO RENTALS IN SAN ANTONIO TEXAS. I FOUND THE CRUISE CONTROL SYSTEM A BIT QUIRKY AND A BIT STARTLING AT FIRST. ONCE THE CRUISE CONTROL WAS SET TO 70 MILE PER HOUR, THE SYSTEM OPERATED FINE AND MAINTAINED THE SET SPEED. HOWEVER, ONCE EVERY 3 OR 4 TIMES THE CRUISE CONTROL WAS DISCONNECTED USING THE BRAKE PEDAL, THEN USING THE RESUME FUNCTION OF THE CRUISE CONTROL, THE VEHICLE WOULD ACCELERATE RAPIDLY PAST 75 MILES PER HOUR. ONCE I DISCONNECTED THE CRUISE CONTROL AND RESET THE DESIRED SPEED, THE CRUISE CONTROL OPERATED NORMALLY. THIS SEEMED TO BE A PERSISTENT BUT INTERMITTENT ISSUE. ONCE I WAS AWARE OF THE POTENTIAL FOR RAPID ACCELERATION AND SPEED OVERSHOOT, I WAS ABLE TO ANTICIPATE AND CONTROL THE VEHICLE FROM RUNNING AWAY. IN LIGHT OF ALL THE ISSUES CONCERNING TOYOTA PRODUCTS, I THOUGH I WOULD BRING THIS TO YOUR ATTENTION. DRIVING CONDITIONS AT THE TIME OF THESE INCIDENTS WERE DRY CONCRETE ROAD, 7 PASSENGERS IN THE VEHICLE, HIGHWAY SPEED OF 70 MILES PER HOUR, OUTSIDE TEMPERATURES WERE BETWEEN 34 DEGREES F TO 70 DEGREES F. HIGHWAY WAS STRAIGHT AND LEVEL. *TR
