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 contact owns 2008 Pontiac Grand Prix. While the contact was driving in approximately 10 mph, the engine stalled and the check engine light illuminated. The engine restarted and the vehicle resumed normally. The failure occurred again at a different time. The vehicle was taken to an independent dealer where the camshaft sensor and rack and pinion were replaced. The failure occurred one week after the repair so the vehicle was towed back to the independent mechanic. A diagnostic testing was performed which failed to detect a trouble code. The vehicle was taken to an authorized dealer and they performed a fuel induction cleaning which did not remedy the problem. The failure mileage was approximately 63,000.

P-0411 code; air control valve solenoid. My check engine light kept going on and then would go off. This process repeated a few times. Bought new gas cap a few times. Finally, light came on and would not go off. Took it to dealer who told me it was the air control valve solenoid and it was not covered under warranty. After looking into this problem online, it seems that this is not a new problem with these cars. has some listings. If you search secondary air pump; Pontiac Grand Prix cars - you get multiple hits.
