I have a 1998 Bonneville SE of which I have replaced the upper manifold twice within 3 years. The first time it cost about $700, and the second time due to engine damage it was $2,300. I agree there should be a class action case against GM, especially when the dealership is replacing the plastic manifold with plastic, knowing it will crack again.
