PURCHASED VEHICLE NOVEMBER 2017. CAR WAS PARKED AND WHEN I STARTED ENGINE THERE WAS A LOUD NOISE. I TOOK IT IMMEDIATELY TO MINI COOPER SERVICE. WAS TOLD THE PASSENGER SIDE ENGINE MOUNT HAD COLLAPSED AND IT HAS ALSO CAUSED DAMAGE TO THE HEAT SHIELD FOR THE TURBO. HOW IS THIS POSSIBLE? NO SIGNS OR PRIOR PROBLEMS. MY MAINTENANCE HAS ALWAYS BEEN UP TO DATE. WHEN IT HAPPENED THE VEHICLE WAS PARKED, HEARD THE RADDLEING.
CRANKSHAFT PULLEY WENT OUT AT 50,000 MILES WHILE IN MOTION MAKING CAR OVERHEAT.
TL* THE CONTACT OWNS A 2015 MINI COOPER. THE CONTACT TOOK THE VEHICLE TO ORLANDO MINI COOPER (350 S. LAKE N. DESTINY DR, ORLANDO, FL) FOR ROUTINE MAINTENANCE AND WAS INFORMED THAT THE ENGINE MOUNTS WERE CRACKED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 52,000. THE VIN WAS UNKNOWN.
TIMING BELT DEFECTIVE LEADING TO SERIOUS ENGINE FAILURE REQUIRING REPLACEMENT. WITHIN TWO WEEKS OF REPLACEMENT ENGINE AGAIN WAS DEFECTIVE REQUIRING A SECOND REPLACEMENT.
EXCESSIVE CARBON BUILD UP ON ENGINE INTAKE PORTS AT 35K MILES. CAR PURCHASED NEW, HAS OIL CHANGES BY DEALER EVERY 5K MILES, AND IS FILLED WITH 92 OCTANE GAS. LOTS OF PEOPLE POSTED ON INTERNET OVER LAST 7-8 YEARS THAT MINIS ARE PRONE TO THIS ISSUE AND BMW HASN'T RESOLVED IT. WHEN ASKED IF THIS SHOULD BE ROUTINE MAINTENANCE, IF THIS WAS DRIVING OR FUEL ISSUES, DEALER SAID NONE OF THE ABOVE. YET RESOLVING THIS ISSUE IS ABOUT A $600-1000K REPAIR! THIS EITHER NEEDS TO BE A ROUTINE MAINTENANCE, RECALL OR SERVICE BULLETIN PUT OUT TO OWNERS/DEALERS. BMW NEEDS TO OWN UP TO THIS ISSUE.
I TOOK MY 2015 MINI IN FOR ITS LAST SERVICE BEFORE CONVERTING MY LEASE INTO A FINANCING DEAL AND PURCHASING CAR. I WAS INFORMED THERE WAS AN ENGINE RECALL DUE TO CRANKSHAFT BEARING PROBLEM. THEY HAVE KNOW ABOUT THIS ISSUE FOR 2 YEARS YET NEVER INFORMED ME. MY DEALER SAYS THEY HAVE DONE HUNDREDS OF ENGINE REPLACEMENTS. WHY IS THIS NOT PUBLIC? I THINK BMWUSA IS HIDING THIS FROM THE PUBLIC! WHILE ITS NICE THEY REPLACE THE ENGINE, THIS IS GOING TO EFFECT MY RESALE VALUE.
