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.

2004 Pontiac Grand Prix Owner Comments

problem #1

Nov 122012

Grand Prix

  • Automatic transmission
  • 112,719 miles


car turned off while driving, lights and power steering, everything. Then it restarted on its own, then shut down again. Was able to coast into the entrance of a parking lot, hit the brake (that worked)and physically turn the key and start it again. Before this happened, every time I would accelerate up to about 23mph the locks would automatically re lock. Did this maybe 14 times on this particular drive alone. Heater fan also was making a ticking sound while on full blast. Had it towed to a GM dealership that could not find any problems at all with the vehicle. I have seen this particular problem on the internet with other 2004 Pontiac GP owners that have had no solutions also. I have children ride in this paid off car and am concerned about the situations this problem is going to put us in.
