Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2002 Toyota Sienna Owner Comments

problem #7

Sienna 6-cyl

  • 60,000 miles


When driving on cruise control and lightly braking the car suddenly alarmingly accelerates. Dealer claims various issues that they tried but non resolved the problem. I am ready to sell and afraid that the buyer might not remember to follow my instruction to turn off the cruise control before braking. I have brought the car to the dealer several times over the years, most recently this year 2014.

I was pulling forward from a red light, slowly accelerating. Someone cut me off, I swerved, and then accelerated into traffic. The car started accelerating on its own, from about 35 mph (where I pulled my foot off the accelerator pad to "hold" the speed but not continue accelerating) up to 55 mph--this happened very quickly, in a smattering of seconds. I remembered reading that you should just slam on the brake and hold it down hard, which I did. This did stop further acceleration, but it did not immediately slow the car. I was able to slow the car in about 10 seconds, though deceleration was very slow. When I finally returned to 35 mph, I did not attempt to accelerate again for about two miles. I stopped at another traffic light, and when I started forward from the light, I did not depress the accelerator pad with my typical force, accelerating at about half the speed I normally would, as I did not want to be taken by surprise by the unexpected sudden acceleration again. The problem did not further repeat itself this evening, but it was quite scary when it happened. I know it was not the floor mat under the pedal, as the floor mat has been cut away from the pedal area and was pulled very far back into the driver's seat area.

The contact owns a 2002 Toyota Sienna. While driving 40 mph the contact released the accelerator pedal and the vehicle continued to accelerate. The contact tried applying the brakes but the vehicle would not slow down completely. The contact shifted the vehicle into neutral and it still did not slow down. The contact then shifted the vehicle into park while the vehicle was in motion. The contact was able to pull the vehicle over and shut it off. The contact restarted the vehicle and the RPM's began to increase rapidly. The contact pumped the accelerator pedal and the RPM's decreased. The vehicle was diagnosed by three local mechanics and neither one of them could duplicate the failure. The dealer was also unable to duplicate the failure and that "gunk" could have composed in the engine, clogged it which would have caused the vehicle to accelerate. The contact stated that the failure is directly related to the current recall for the pedal. The failure mileage was 83,271.

I drive a 2002 Toyota Sienna xle and have experienced a lurching/accelerating when I am at a full stop. When it happens (which is becoming more frequent) it seems awkward. Now, I wonder is this part of the accelerator problem too?

Toyota Sienna van appeared to have sudden acceleration problem when stopped at stop sign. Engine revved up as accelerator was about to be applied, so I had to apply brakes as car was making sudden movements. Quickly put car into neutral position.
