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.

Found a broken off exhaust manifold bolt on driveway 3 years ago. Found another broken one today. Both are from the same side. Now instead of 6 bolts I have 4 bolts. This is causing an exhaust leak, engine light and emissions problems that harm the environment. This is an ongoing problem per this article: Https://

Wife driving truck to work " reduced engine power", message came on the dash, and also said traction control was disabled. Power was reduced gradually to ten miles per hour. She floored the gas, nothing. Turned it off, restarted it, nothing. Engine light and traction disabled lighted were illuminated. Also the rear mirror temperature display flickers all the time. Drl burn out almost daily. Gmcs have major electrical issues before people start dying. Imagine a car shutting down on you while on the highway. That an accident waiting to happen. The rear wiper works when it feels like working, there is also a message about fixing the ride control. For all the bail money GMC got, they should recall these mistakes they made.
