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.
