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.

Faulty intake manifold gasket. This is a common problem with these cars and all owners with this problem should be writing GM and demanding they cover the cost of repairs. It is their fault and they know that this is a problem with all these cars. Let's support each other so our voices will be heard
