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 1998 Cadillac Seville. The contact stated that whenever the vehicle stopped or driving various speeds, the engine would overheat and a message informing him to add coolant would display on the instrument panel.

The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 138,000 and the current mileage was 140,000.

Head gasket is blown. Vehicle milage is only 78, 000. Consumer doesn't understand how a vehicle that doesn't receive a tune-up until 100,000 miles have a head gasket failure at 78,000. Consumer was told that this problem is a common ocurrance and consumer feels that is unacceptable.
