NHTSA Complaint #10560094 — 2010 MINI COOPER S

AT ABOUT 42000 MILES, I STARTED TO NOTICE A RATTLE COMING FROM THE ENGINE WHEN THE ENGINE WAS FIRST STARTED. THE RATTLE WAS MOST NOTICEABLE BETWEEN 2000 AND 3000 RPM. THIS RATTLE ALSO COINCIDED WITH THE WEATHER TURNING COLDER. THE RATTLE CONTINUED TO WORSEN OVER TIME, AN OIL LEAK DEVELOPED, AND THE CHECK ENGINE LIGHT EVENTUALLY CAME ON. AFTER SEARCHING THE INTERNET AND CALLING MY MINI DEALERSHIP, I DETERMINED THAT THE TIMING CHAIN TENSIONER WAS MOST LIKELY AT FAULT. I ORDERED THE PART AND REPLACED IT MYSELF. DURING THE PROCESS OF REPLACING THE TENSIONER, I FOUND THAT THE OLD TENSIONER WAS LOOSE IN ITS SOCKET. AFTER REPLACING THE PART, THE ENGINE RAN SMOOTHLY AND CONTINUES TO RUN SMOOTHLY. *TR
