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.

Clock and outside air temp readings are so small, you can't see them, without taking your eyes off the road, long enough to bend over close to the radio. This is as bad as someone using a cell phone to send and receive text. I have driven off the road twice, but have not crashed yet. My GM dealer says, the readings can not be made larger, and to be very careful.

  • 89 miles
The headlights on this truck are unsafe, they do not project enough light ahead for safe driving at night. One has to depend on the street lighting or stars. I have come close to hits others on the roads for the lack of projection of these lights. The truck becomes a hazard on the highway do to the slow speed one has to travel to stay within the headlights. Please address this with GMC before someone is hurt or killed.

I am having problems with door chime and dome lights not shutting off with key in ignition on different occasions when door is closed. I also have the same with them not coming on when opening door on different occasions. It started approx. A month after purchasing and still happening now. It has not happened at the dealership yet and GM says they will not check into it unless a GM rep. Is a witness to it happening.
