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.

  • 45,000 miles


2008 Pontiac G6 sedan. Brake lights are stuck on until brake pedal is depressed, then lights go off momentarily and come back on. Other motorists following cannot determine whether or not I am actually braking which is obviously dangerous. This failure has yet to cease and is a constant problem as it is my only vehicle to get to and from work. The vehicle was taken to the certified dealership under warranty and the problem has been refused to be covered under warranty.

Door ajar alarm sounds when all doors are closed. This causes the interior dome light to come on. This also stops the door locks from locking when shifting the car into drive. The dome light will come one after all doors are shut and the doors are locked. The dealer stated that the door lock assembly will need to be replaced. The dealer also stated that others have come in with the same problem.

G6 4-cyl

  • 3,368 miles
Pontiac 2008 G6 3,368 mileage power steering error, then transmission malfunction. 4/25/08 phoned dealership and scheduled repair for 4/28/08. Had car towed to dealership on 4/27/08. 4/28/08 dealership discovered two broken wires in the vehicle speed sensor harness. They indicated that something had severed the wires and that the repair would not be covered by the warranty. I believe that there is a design flaw with the wiring harness. Why would two wires be left unshielded from the elements? the dealership via my request received an one time customer goodwill warranty approval. I had the mechanic show the area in question. He has reinforced the wires with electrical tape. It appears to be a great repair. I am not sure why the manufacture did not do this originally. Error codes PO722, coooo and PO700. I am concerned that this design will cause problems for other car owners. And could pose a safety issue if the wiring is severed at highway speed.
