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.

problem #1

Dec 292005

Grand Marquis 8-cyl

  • Automatic transmission
  • 8,100 miles
On three occasions when shifting from park to reverse the engine sped up (accelerated drastically) causing the wheels to spin and only by quick application of the brake was an incident avoided. I drove into a parking space, put the car in park, then not satisfied with the position I attempted to back up, that's when the car accelerated.
