2008 Cobalt, gave us no indication of problems. Now dealer is saying this 5 year old car may have slipped it's timing belt and destroyed it's head and valves requiring a new motor. This should be recalled because chevy does not recommend timing chain maintenance at a set mileage. It's supposed to last. The fact that such a big engine failure can happen to so many of these cars just 5 month after warranty end at 90 thousand miles makes this a design flaw in my opinion.
