NHTSA Complaint #10852333 — 2008 CHEVROLET COBALT

I STARTED MY CAR IN MY DRIVEWAY, IT STARTED AND THEN STALLED IMMEDIATELY AND WOULD NOT START AT ALL. I DIAGNOSED IT ALONG WITH MY FRIEND WHO IS A CERTIFIED MECHANIC. THE CAM CHAIN GUIDES BROKE AT LESS THAN 79000 MILES, CAUSING SLACK IN THE CAM CHAIN WHICH CAUSED IT TO JUMP TEETH ON THE INTAKE CAM, THROWING IT OUT OF SYNCHRONIZATION. THIS CAUSED THE INTAKE VALVES TO BE OPEN WHEN THE PISTON REACHED THE TOP OF ITS TRAVEL, WHICH BENT THE VALVES. THIS IS A VERY COMMON ISSUE ON THE 2.2 ENGINES, BUT VERY UNUSUAL FOR SUCH A LOW MILEAGE VEHICLE. THE ENGINE HAS A 100,000 MILE WARRANTY BUT ONLY FOR 5 YEARS. I ONLY DRIVE ON AVERAGE 10,000 MILES A YEAR. THE ENGINE IS WELL BELOW 100,000 MILES AND GM WILL NOT ADMIT THAT THEY HAVE A DESIGN FLAW ON THESE ENGINES AND WILL NOT MAKE THIS REPAIR FOR ME UNDER WARRANTY.
