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 belt tensioner is made of plastic which broke disabling the car which had to be towed. Oil leak came from lower intake manifold gasket, gathered around bottom at oil pan, upper intake manifold gasket, also made of plastic leaked antifreeze into engine. Tensioner was replaced with same plastic because it has not been re-designed, same with the intake manifold gasket, therefore, it will give the same problem in the future. A lot of other people are having the same problem and GM refuses to do anything about the problem.
