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.

2009 Pontiac G8 Owner Comments

problem #1

A tapping noise was heard when the engine was running - whether the car was at idle or moving. The tapping would not cease. The vehicle was taken to the dealer, where they discovered that the #2 valve lifter had collapsed into the camshaft and damaged the camshaft. All 16 lifters, camshaft and associated gaskets were replaced. Had we continued driving the car, more defective lifters would have collapsed, causing the engine to seize. At that point, the engine would have to be replaced. The lifters are defective in all GM cars with this engine (see service bulletin 10-06-01-007D).
