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.

Purchased this vehicle from a dealer. The next day the truck was dead. It has since had the battery replaced 3 times. The exhaust manifold cracked at 82,000. The number 4 position on the blower does not work. The stabiltrak lights come on for no reason and go off for no reason. With all of the complaints, something should be done.

Was driving and suddenly the exhaust got real loud. Took it to repair facility and they said that the exhaust manifold had cracked. GM knows this is a bad part, and a safety part, but they only advanced the warranty 20,000 miles. I have never had an exhaust manifold crack on any vehicle, besides one that is 6 years old.
