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.

The brake and accelerator pedals are too close together and at the same height. On numerous occasions, when attempting to brake I found myself accelerating since the brake and accelerator were both depressed. The pedals are not adjustable and I really have to concentrate when braking to avoid the accelerator pedal or my car just keeps on going.

Grand Marquis

Gas pedal went all the way to the floor and would not release. I kept hitting the pedal to try and release it for about 2 miles. I kept my foot on the brake to try and slow the car down, but that didn't help. The floor mat was not under the pedal because it is too short to reach it. After hitting the pedal as hard as I could numerous times it released.

Ltr fwd email fm (NY) reporting incident of sudden unintended acceleration fm owner of a 2007 Mercury Grand Marquis, reply to massapequa park district ofc. The consumer stated while driving on the turnpike, the vehicle suddenly accelerated and he could not stop it, until he turned off the engine and coasted quite a distance. The vehicle was towed to a Ford dealership and the dealer claimed there was carbon buildup in the air filter which caused the sudden acceleration. The consumer stated he experienced the same problem again. The consumer believed it is the same problem Toyota's are having.
