2001 Toyota Sienna Cruise Control Problems

Your van's engine is accelerating on its own without you pressing the gas pedal. After you release the brakes, the engine revs up and the van moves forward at traffic speed on its own, and applying the brakes harder doesn't stop this from happening — you've had to shift into Park to prevent moving into pedestrians or your garage. This happens randomly and no check engine light appears, even after diagnostic scanning. The issue likely involves the throttle control system, which may need inspection or replacement of the throttle body or accelerator pedal sensor.

2001 TOYOTA MINIVAN UNPREDICTED ACCELERATED WHILE DRIVING ON HIGHWAY. PULLED OFF TO EXIT RAMP AND DID AGAIN SO HAD CAR TOWED. *TR

I WAS DRIVING A 2001 TOYOTA SIENNA. I TURNED LEFT INTO A PARKING SPACE AND PULLED FORWARD. WHILE STILL IN DRIVE, RATHER THAN STOPPING, THE CAR CONTINUED TO ACCELERATE SLOWLY, RAN OVER A WOODEN PARKING BARRIER, AND CRASHED INTO A CONCRETE WALL A FEW FEET AWAY. *TR

OUR 2001 TOYOTA SIENNA HAS BEEN EXPERIENCING GAS PEDAL PROBLEMS FOR THE LAST TWO YEARS. FROM A STOPPED POSITION, THE GAS PEDAL STICKS UNTIL EXCESSIVE PRESSURE IS APPLIED. WHEN THE ACCELERATOR FINALLY ENGAGES, THE CAR LURCHES FORWARD. THIS PROBLEM MAKES THE VEHICLE FRIGHTENING TO DRIVE. THE FIRST TIME WE BROUGHT THE CAR TO THE TOYOTA SERVICE DEPARTMENT (TOYOTA OF SANTA MARIA, CALIFORNIA) ABOUT THIS ISSUE WAS FEBRUARY 2008 (ODOMETER 101,112). THE SERVICE DEPARTMENT TOLD US THEY COULD NOT DUPLICATE THE PROBLEM BUT SERVICED THE THROTTLE BODY AND LUBRICATED THE EXPOSED THROTTLE CABLES. THE GAS PEDAL RESPONDED BETTER. IN NOVEMBER 2009 WE STARTED EXPERIENCING THE PROBLEM AGAIN AND ON DECEMBER 10, 2009 WE TOOK THE VEHICLE INTO THE SERVICE DEPARTMENT (ODOMETER 111,596). WE REQUESTED A SIMILAR SERVICE TO SEE IF IT WOULD FIX THE PROBLEM BUT THE SERVICE DEPARTMENT CLAIMED TO NOT KNOW WHAT THEY HAD DONE ON THE PREVIOUS VISIT TO 'FIX' THE STICKY GAS PEDAL. THEY COULD NOT DUPLICATE THE PROBLEM AND WE TOOK THE VEHICLE HOME. WITHIN THE SAME DAY THE ACCELERATOR WAS STICKING. WE FELT UNSAFE DRIVING OUR TWO SMALL CHILDREN IN THE VEHICLE AND PARKED IT IN THE GARAGE FOR A MONTH UNTIL WE COULD TAKE IT BACK TO THE SERVICE DEPARTMENT. ON JANUARY 11, 2010 WE BROUGHT IT BACK AND INSISTED THEY FIX THE PROBLEM. THEY COULD NOT DUPLICATE THE PROBLEM. WE WERE ASSURED THAT THERE WAS NOTHING UNUSUAL WITH OUR VEHICLE, PERHAPS JUST SOME CARBON BUILD UP ON THE THROTTLE BODY PLATE. WE DIDN'T FEEL SAFE DRIVING THE VEHICLE HOME AND LEFT IT AT THE SERVICE DEPARTMENT WHERE IT HAS REMAINED TO THIS DAY. ON JANUARY 21, 2010, TOYOTA ANNOUNCED A RECALL DUE TO A STICKING GAS PEDAL THAT, IN PART, DESCRIBES OUR ISSUE. OUR 2001 SIENNA IS NOT INCLUDED IN THIS RECALL. *TR

5 MONTHS AGO MY SON WAS DRIVING MY CAR AND IT SUDDENLY ACCELERATED AND HE COULD NOT GET THE CAR TO STOP EVEN WHEN HE PUT ON THE BRAKE. WHEN I GOT THE CAR, I STARTED THE ENGINE AND IT LUNGED FORWARD, BUT I PUT THE CAR IN NEUTRAL AND THE ENGINE JUST RACED. I ULTIMATELY TOOK THE CAR TO MY MECHANIC AND HE TOOK IT SOMEWHERE ELSE WERE THEY REPAIRED THE PROBLEM AFTER TWO ATTEMPTS. MY CAR DID NOT HAVE ANY DRIVER SIDE FLOOR MATS IN IT. *TR

THANK YOU IN ADVANCE FOR YOUR CONSIDERATION OF THIS COMPLAINT. MY WIFE AND CHILDREN WERE NEARLY INVOLVED IN A SERIOUS ACCIDENT YESTERDAY DUE TO SUDDEN UNCONTROLLED ACCELERATION IN OUR MINIVAN. BEFORE YOU EVEN CONSIDER THAT IT MAY BE DRIVERS ERROR, AS EVIDENCED BY THE MYRIAD OF DISCUSSION ON THIS MATTER ON THE INTERNET, THE PROBLEM WAS CONFIRMED BY THE TOW TRUCK DRIVER AND ME; THE VAN CURRENTLY IS STUCK IN FULL ACCELERATION UPON STARTING---I TESTED THIS NUMEROUS TIMES YESTERDAY AND TODAY. THERE IS NO OBSTRUCTION TO THE THROTTLE CABLE, PEDAL, NOR A FLOOR MAT ISSUE. I HAVE CLEARLY CHECKED THESE ITEMS. THERE ARE NUMEROUS SIMILAR COMPLAINTS ONLINE BUT APPARENTLY THEY HAVE NOT BEEN ACKNOWLEDGED/ADDRESSED BY TOYOTA OR NHTSA. THANKS. *TR
