NHTSA Complaint #10469543 — 2007 MINI COOPER S

TIMING CHAIN AND TENSIONER FAILURE MENTIONED BY OTHERS ALSO OCCURRED IN MY CAR. FAILURE IN MY CASE WAS PROGRESSIVE: STARTED WITH ROUGH STARTS, NOISY IDLE (FROM CHAIN IMPACTING COVER!) PROGRESSED TO NON-EXISTENT ACCELERATION ABOVE 4000 RPMS (A SAFETY ISSUE ON THE HIGHWAY) . BROUGHT THE CAR TO MECHANIC AND WHILE HE WAS INVESTIGATING THE OBVIOUS AIR LEAK, CAR FAILED TO START. DEALER EVENTUALLY DISCOVERED BENT VALVES FROM IMPACT WITH PISTON PREVENTING PROPER SEAL, BUT ONLY AFTER REPLACING SNAPPED TENSIONER GUIDES AND TIMING CHAIN DROPPED INTO OIL PAN FOR $2,525. HAD THIS OCCURRED WHILE DRIVING IT POSES A SIGNIFICANT SAFETY ISSUE. THEN THEY TELL ME THEY CAN REPLACE ALL VALVES FOR $4,500. TOTAL COST, OVER $7,000. EFFECTIVELY, THIS IS A TOTAL ENGINE FAILURE AND IT WOULD BE CHEAPER TO DROP IN A COMPLETE NEW ENGINE. MINI AND THEIR DEALERS ARE WELL AWARE OF THIS PROBLEM AND AS IT CAN - AND HAS - RESULTED IN FAILURES FOR OTHER MOTORISTS AT HIGHWAY SPEEDS IT POSES SIGNIFICANT SAFETY RISK AND SHOULD BE ADDRESSED WITH A RECALL. *TR
