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 biggest problem (out of many) that makes this vehicle unsafe, stressful, and discomforting to drive is how it will randomly decides to raise the idle to 900+ RPM (in gear) and basically drives it's self. During this condition it is very difficult to operate vehicle. Because of its random pattern it caused me to have an accident that resulted in $3500 in body damage to the truck. Thank god no one was hurt. Wear and tear is drastically increased as the vehicle is trying to drive on its own as I'm trying to stop at traffic light, stop signs, or simply parking. Drive-train is banging, brakes are working harder, and fuel is being wasted. Now, add a payload or trailer as I often do and problems are magnified. Essentially the vehicle is aging and wearing its self out before its time. I have been ordered by pima county court to have the vehicle fixed or replace. The officer that gave me the citation witnessed the high engine idle and agreed that it would be difficult to stop especially with a loaded trailer as I had that day. Officer also testified this in court on 11/4/2015. There is a current law suit in California for this defect. My local dealers will not work on vehicle anymore do liability and told me take it up with GM. GM has provided no assistance.
