| Description of the problem | This vehicle has a magnesium engine block, and therefore uses aluminum bolts to fasten the head and the valve cover to the engine block. With normal driving, multiple cylinder head and valve cover bolts spontaneously snap off. This type of failure has the potential to disrupt the timing chain and loss of compression, leading to catastrophic engine failure. |
