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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

On October 27, 2010, my wife was driving with me in the car and she started to brake for a red light. She was going about 30 miles per hour. As soon as she applied the brake, the engine accelerated and she had to use a large amount of braking pressure to stop the car. As soon as the car stopped, she took her foot off the brake and the engine returned to idle. Yesterday, I was driving the car at approximately 55 mile per hour and started to move into the passing lane when the traffic light ahead turned red. I applied the brake and the same thing happened. I had to apply a large amount of pressure on the brake peddle in order to stop the car while the engine raced on. As soon as the car stopped, the engine returned to idle and the problem was over. Yesterday, I took the car to the dealership where it was purchased and they kept the car overnight to run various tests. They found nothing. I picked the car up this afternoon and am going to now take it to another dealer for inspection.

Brake and gas pedal to close together when applying brakes also hit gas has happened many times almost requires a conscious effort to avoid this problem.

The vehicle accelerateds when the brake pedal is depressed. Because the brake pedal and the gas pedal height is nearly the same height and when depressing the brake pedal you can also depress the gas pedal causing the vehicle to accelerate. The vehicle accelerates when the brake pedal was depressed.
