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.

Grand Marquis 8-cyl

  • Automatic transmission
  • 16,890 miles


: the contact stated while approaching a stop under normal braking, the vehicles engine revs and surges forward. The brake pedal must be depressed to the floor to stop the vehicle. This happened 5 times and the vehicle was inspected by the dealer however; the problem could not be duplicated. The vehicle was driven over 6,000 miles when the problem returned. It was taken back to the dealer for service and again the dealer was unable to duplicate the problem. The consumer believed there is a problem with the transmission. Updated 04/06/06.

New 2004 Mercury marquis. Had car for one day. Attempted to make a quick left turn by depressing accelerator to the floor. Motor started revving up but the car would not move. Let off gas and transmission engaged. After making the turn, stopped the car, still in drive, put the gas pedal to the floor. The engine went into high revs and the car moved very slow, released the gas and the transmission once again engage. Took car back to dealer and they are replacing the transmission.
