NHTSA Complaint #10496231 — 2007 GMC YUKON

WHEN VEHICLE WAS INSPECTED I WAS TOLD THAT THERE WAS AN EXHAUST LEAK IN EXHAUST MANIFOLD. DEALERSHIP FOUND A BROKEN BOLT ON LEFT SIDE AND REPLACED IT. I HAVE JUST BEEN INFORMED THAT I NOW AS OF 01/30/2012 WITH 62,760 MILES I HAVE ANOTHER BOLT BROKEN ON THE RIGHT SIDE. AFTER RESEARCHING ON INTERNET IT IS OBVIOUS THAT GM HAS A DESIGN FAULT IN USING LOWER GRADE BOLT WHICH ARE BREAKING IN LARGE NUMBERS. I IMPLORE THE NTSA TO REQUIRE GM TO REPLACE THESE DEFECTIVE BOLTS EITHER BY RECALL OR AS INCIDENT OCCURS AT NO COST TO CAR OWNERS. I AM TOLD THAT THE EXHAUST LEAK CAN CAUSE FAILURE OF THE CATALYTIC CONVERTER AND OTHER ENGINE FAILURE PROBLEMS WHICH CAN RESULT IN SAFETY ISSUES. *TR
