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.

2007 GMC Acadia Owner Comments

problem #2

Sep 202008


  • 30,286 miles


Check engine light / stabilitrak warning light leading to discovery the engine cylinder head and valves were damaged and needed to be replaced. Total repair took 33 days. Apparently this is an ongoing problem with this GM engine. Numerous internet sites state improperly manufactured camshaft components are the possible cause. My camshafts were not replaced, but I do suspect they were probably the cause based on present information available to me.
