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.

Recent purchase of a new 2010 Toyota Avalon, now involved in a recall- had a defective accelerator pedal, which was recently replaced by the Toyota dealership. We occasionally feel a "lurch", when starting up the car or backing up.

2008 Toyota Avalon February 16th and 17th my car jolted forward at stop light. I was able to stop the car but, it did go about 50ft before I could control the steering wheel and stop the car. I had this serviced at lake norman Toyota(704) 875-9199 earlier this month. Upon calling in today about my car, was informed the repair had not been completed. Why in the heck did the dealership tell me they could not find an issue and the car was drivable? my life and that of not only my family but others is at stake. I want action, truthfulness and accountability from Toyota and the usa.

My 2010 Toyota Avalon does infact accelerate on it's on when you are approaching a traffic light or stop sign. When you let off the gas and let it coast at about 20mph it will start to accelerate on it's own. I do not in any way believe this is a pedal problem. Your investigators are welcome to drive it. I purchased the car on Dec 31st.

Avalon 6-cyl

  • Automatic transmission
  • 2,625 miles
The contact owns a 2010 Toyota Avalon limited equipped with a dynamic laser cruise control. While attempting to pass another vehicle with the cruise control engaged at speeds of fewer than 65 mph, the vehicle lost acceleration. The driver attempted to depress the brakes to shut off the cruise control, to no avail. The vehicle would not accelerate and she allowed the vehicle to drift off of the highway. The vehicle was taken to the dealer where they could not duplicate the failure. No repairs were made to date to correct the failure. The cruise control mechanism had not been engaged since the incident. The failure and current mileages were 2,625. Updated 03/12/10. Updated 09/21/10

1. on three occasions the accelerator pedal was jammed open by factory cloth floor mat. Removed the mat. 2. on multiple recent occasions when the car is started and placed in reverse to back out of a parking space the car will not move even if the accelerator is pressed. Car seems as if the wheels are chocked. Then when car does move it accelerate quickly in reverse. Have discovered when this happens the traction control appears when the car is shifted into reverse and stays lit for a period of time, then the light goes out and the car simultaneously feels as if the brakes have been released even though the brake pedal was not depressed. It is easy to understand how a driver could press the accelerator to get the vehicle to move and then have the car shoot backwards causing damage or injury. 3. on three separate occasions while wearing boots I removed my foot from the accelerator and depressed the brake pedal only to have the vehicle instead of decelerating, accelerate very quickly. The reaction each time was to press the brake pedal even harder resulting only in the vehicle accelerating even harder. On one of those occasions it occurred backing out of a driveway and although I was able to stop the vehicle quickly it nonetheless accelerated several feet into the middle of a street. It is clear that these three incidents occurred because of the proximity of the brake and accelerator pedals and inadvertently but simultaneously depressing both. I believe the situation is aggravated by the fact when depressing the brake pedal you cannot feel the accelerator pedal under your foot and have no idea you are pressing the accelerator until you go through the mental process of trying to determine why the harder you depress the brake the faster the car goes. It is easy to understand why one might panic and "stand" on the brake pedal only to have the car accelerate to a very dangerous speed. My 190 mph motorcycle doesn't scare me, the venza does.
