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.

2006 Mercury Grand Marquis Owner Comments

problem #2

Dec 212009

Grand Marquis

  • 40,000 miles


Sporadically and without warning, my cruise control will activate causing the vehicle to immediately accelerate. I had been using the control but had de-activated it but depressing the brake which leaves the unit "on" but not activated.

Grand Marquis 8-cyl

  • Automatic transmission
  • 200 miles
- the contact owns a 2006 Mercury Grand Marquis. When the engine was started it would rev very high. When the brakes were applied the vehicle would abruptly go into drive. The failure occurred intermittently. There were no warning indicators. The Ford dealer was unable to diagnose or duplicate the failure. The failure mileage was approximately 200 miles, and the current mileage was 11,000 miles.
