NHTSA Complaint #10630307 — 2009 CHEVROLET COBALT SS

CAR SUDDENLY SHOWED SYMPTOMS OF COOLANT LOSS A DYE AND PRESSURE TEST WAS COMPLETED AND FOUND NO EXTERNAL LEAKS. I DROVE THE CAR TO WORK THE NEXT DAY 15 MINUTE COMMUTE AND UPON ARRIVING LOW COOLANT INDICATOR POPPED UP I CHECKED THE DIP STICK TO CONFIRM MY FEAR THAT THE COOLANT WAS ENTERING MY OIL SYSTEM 1-WAY. HAD THE CAR TOWED TO THE DEALERSHIP AND AFTER 2 WEEKS OF TEARDOWN VERIFIED THE ENGINE HAD NOT SIGNS OF ABUSE AND THE HEAD AND HEADGASKET WAS NOT WARPED OR LEAKING/BLOWN. THE CAR WAS 2 MONTHS OUT OF WARRANTY AND GM DECLINED WARRANTY. LUCKILY I HAVE A 3RD PARTY WARRANTY AND THEY AGREED TO COMPLETE THE WORK DUE TO KNOWN ISSUES WITH SAID ENGINE/ SYMPTOMS . GM NOTIFIED ME THEY DID NOT HAVE A ENGINE AVAILABLE AND IT WOULD BE UNTIL OCTOBER BEFORE THE ENGINE WAS REPLACED AND DENIED TO OFFER RENTAL WHILE I WAITED AFTER A MONTH OF FIGHTING WITH GM CUSTOMER SERVICE THEY AGREED TO LEND A RENTAL CAR. TO THIS DAY MY CAR SITS IN A LOT ROTTING AWAY. A SHORT GOOGLE SEARCH OF CRACKED LNF ENGINES WILL BRING A HOST OF RESULTS EVEN MAJOR GM AFTERMARKET PERFORMANCE COMPANY'S ARE AWARE OF DEFECTIVE CASTINGS OF THE LNF ENGINE ..
