NHTSA Complaint #10400924 — 2008 MINI COOPER S

2008 MINI COOPER S - ENGINE FAILURE DUE TO FAULTY VACUUM PUMP. WHILE DRIVING MY WELL MAINTAINED 2008 MINI COOPER S UNDER NORMAL DRIVING CONDITIONS, THE ENGINE ISSUED A LOUD, BRIEF METALLIC NOISE AND STOPPED RUNNING. THE ENGINE WAS STILL TURNING, BUT WAS NOT RUNNING. HAD THE CAR TOWED HOME. UPON INSPECTION OF THE VALVE TRAIN, BY REMOVAL OF VALVE COVER, THE EXHAUST CAM GEAR WAS SHEARED OFF AND SEVERAL VALVES HAD BEEN BENT. THE EXHAUST CAM WOULD NOT TURN. FURTHER RESEARCH INTO THE MATTER INDICATES A FAILED VACUUM PUMP CAUSED THE EXHAUST CAM TO LOCK-UP AND SHEAR OFF THE CAM SPROCKET BOLT. THE PISTONS THEN IMPACTED THE VALVES CAUSING SEVERE INTERNAL ENGINE DAMAGE. THIS CAR ALSO FELL VICTIM TO THE "COLD START" ISSUE AND HAD THE VALVE TRAIN REPLACED AT 60,000 MILES. MINI HAS INDICATED THAT SINCE THE WARRANTY PERIOD HAS EXPIRED, THEY WILL NOT ASSIST IN THE REPAIR. I SUGGEST THIS ISSUE SHOULD RESULT IN A PRODUCT RECALL OF ALL R56 EQUIPPED MINI VEHICLES FOR REPLACEMENT OF THE VACUUM PUMP. THIS ISSUE IS WELL DOCUMENTED ON THE INTERNET, AND BMW IS AWARE OF THE PROBLEM. THIS IS EVIDENCED BY THE PROCEDURE EXECUTED TO REPAIR THE "COLD START" ISSUE INCLUDES A STEP TO REMOVE AND INSPECT THE VACUUM PUMP FOR BINDING. *TR
