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 a 2006 GMC Envoy. While driving approximately 30 mph, the vehicle vibrated and the engine stalled intermittently. Prior to the failures, the engine warning light illuminated on the instrument panel. The vehicle was taken to an authorized dealer and they replaced the intake valve, head gasket, timing belt, and cylinder head. The failures recurred on a separate occasion. The vehicle is currently not being driven due to the safety risk involved. The contact will take the vehicle to the authorized dealer for diagnostic testing and repair. The failure mileage was 14,000 and current mileage was 16,000.
