LEFT AND RIGHT REAR DOOR LOCKS WILL NOT REMAIN LATCHED, WHETHER LOCKED OR UNLOCKED. THESE LATCHES WERE REPLACED IN JULY 2006 AND THE REPLACEMENT LOCKS ARE NOW DEFECTIVE AS WELL. VAN DEVERE DEALERSHIP IN AKRON, OHIO CHARGED $100.15 TO DETERMINE LOCKS WILL NOT WORK; ADVISED ME TO CALL GM CUSTOMER SERVICE. CALLED GM CUSTOMER SERVICE 866-790-5600 X 32380 COMPLAINT FILE 71-585106455; ROBERT JOHNSON STATED THAT THE SERVICE MANAGER OF THE REPAIRING DEALER IN JULY 2006, PREMIER IN RITTMAN, OHIO WOULD NOT REPLACE LOCKS BECAUSE PARTS BEYOND 12 MONTH WARRANTY. I EXPLAINED THAT THIS WAS A SAFETY ISSUE, AND EXPLAINED THE DANGER OF DEFECTIVE LOCKS; ROBERT JOHNSON STATED THERE WAS NOTHING ELSE HE WOULD DO. ASIDE FROM THE POOR QUALITY, LOCKS ARE CRUCIAL TO VEHICLE SAFETY, AND LOCKS ON A 2005 VEHICLE SHOULD NOT FAIL IN 2006 AND 2007. MOREOVER, I AM APPALLED THAT GM WOULD NOT INSIST THAT THESE BE REPLACED IMMEDIATELY AT COMPANY EXPENSE, CONSIDERING THE SAFETY RISK AND EMBARRASSING LACK OF QUALITY. *TR
