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.

: the contact stated the automatic sliding door locked by itself and would not open by the key or power controls. The vehicle was seen by a dealer for replacement of the power door lock motor. Although the door lock problem was corrected, the door rattled while driving at various speeds. The vehicle is currently awaiting further inspection by the dealer. Updated 5/10/2006 - the vehicle rolled back while on hills.

The contact tried to using the horn but most of the time could not get it to blow. Even when pressing hard on the horn it would not work. One must hit it correctly in order to get it to work properly. He has taken the vehicle to the dealer, who agreed it took a lot of force for the horn to work. The dealer had a representative look at the horn. The representative was doubtful that GMC would fix the horn. He stated it was a sensor that failed, it send a message to the steering wheel, and it was sending wrong information. When pressing the accelerator the brakes would clamp down and slow down the vehicle. This would cause the vehicle to stop while in motion to continue on. The contact stated the headlights brighten and dim on their own. The dealer replaced the alternator in order to correct the problem. The vehicle was having the same problem.

The contact stated had a technician from GM look at his car because he was having many problems with his horn. E noticed problems with the horn on or around 5-20-05. It was very hard to push. The horn. You almost have to take a hammer to get it to blow. The dash lights are also very dim. He has found several complaints on the NHTSA website about the horn not blowing. Transmission kicks into passing gear too much going up slight grades on the interstate at 65-70 mph. The contact has driven other cars on the same interstas with the same average loads and with less horsepower and they didn't kick into the passing gear as much. The tech that GM sent out, said everything was normal.
