NHTSA Complaint #10873758 — 2011 MERCEDES-BENZ GL350

HELLO. MY VEHICLE HAS EXPERIENCED TWO SEVERELY ELONGATED TIMING CHAINS IN 30,000 MILES OF DRIVING. TOTAL MILES ON THE VEHICLE ARE 114,000, AND THE VEHICLE IS A 2011. I HAVE BEEN ADVISED THAT IF THE TIMING CHAIN FAILS DURING DRIVING, IT WILL CAUSE AN ENGINE STALL, AND MAY POTENTIALLY CAUSE SEIZURE OF THE TRANSMISSION AND WHEELS, CAUSING A SEVERE SAFETY HAZARD. AT A COST OF APPROXIMATELY $8,000, THE TIMING CHAIN AND ALL RELATED TIMING COMPONENTS HAD BEEN REPLACED APPROXIMATELY 15 MONTHS AGO, AND NOW, THE PROBLEM HAS RECURRED. IN SPEAKING WITH OTHERS, THIS IS NOT AN ISOLATED INCIDENT; HOWEVER, RECURRENCE OF THE PROBLEM SUGGESTS TO ME THAT THERE IS AN INHERENT DEFECT IN THE ENGINE THAT CAUSES TIMING CHAINS TO FAIL.
