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.

The problem started while backing a trailer and turning. The stabiltrack light came on and the steering wheel jerked out of my hand. It happened a few more times and then the truck died. Later while driving the stabilitrack light would flash on and the dic would go black. The a.C. would also go out and come back on. It would also do this when turning on the signal light or stepping on the brake pedal. I was in a parking lot today driving slowly and the St message came then the dic went black again. When I tried to turn the wheel it started jerking back and pulled out of my hand. It seems that shutting the truck off and restarting solves the problem for a day or two. This is a very unsafe issue and I have seen and read many complaints. I have been a huge fan of GM and all I have ever owned were GM vehicles, but this issue is making me wonder if I should have bought a Ford instead. It seems that GM is not worried about recalling because of this safety issue, which there are many complaining of the same thing, and my warranty is about to run out.

Vehicle will lose power and shut off while driving, while in reverse I have had the steering wheel ripped out of my hands. Random error messages on dic, random starting issues. Taken to shop multiple times, they cannot find an issue.

Sierra 1500 8-cyl

  • 540 miles
Initial vehicle start was fine. After dropping my son at his summer program, I returned to the vehicle and the engine would not start. All of the instruments and gauges powered on, but when I turned the key, nothing happened. I turned the power back to the off position and attempted to start again. I repeated this procedure eight separate times before the truck finally started. I am foreseeing a 2nd trip to the dealer's service department soon, but 1st for this issue. My 1st trip was due to the intellilink infotainment system going black. I took the truck to the dealer and was told there was a recall for the radio module to be reprogrammed. The reprogramming did not work and I had to wait another business day for a new radio module to be ordered and installed. I am beginning to doubt my purchase of this vehicle. I have owned it less than 1 month and I am anticipating another service department visit soon.
