CLUTCH SLIPPING, TAKING A LOT OF RPMS TO GET MOVING, LOT OF CHATTER ACCELERATING AROUND CORNERS (LIKE MAKING A TURN FROM OUT OF A DEAD STOP). STALLED OUT AT BUSY INTERSECTIONS, AND AT TRAFFIC SIGNALS ON HILLS, NEARLY CAUSING A FEW ACCIDENTS. BACKING UP INTO DRIVEWAY, JUST TRYING TO GET OVER THE CURB SLOPE WAS ENOUGH TO CAUSE A BURNING SMELL FROM THE CLUTCH. RESEARCH SHOWS THAT THE CLUTCH IN THIS MAKE/MODEL YEAR SUBJECT TO PREMATURE AND EXCESSIVE WEAR (ONLY 7 YRS AND 40K MILES ON THIS VEHICLE - BY CONTRAST, I ALSO DRIVE A VW 10 YEARS OLDER WITH TWICE THE MILEAGE, CLUTCH STILL WORKING PERFECTLY). REPAIR TECH REPORT STATES CLUTCH WORN DOWN TO THE RIVETS, FLYWHEEL HEAVILY SCORED - VEHICLE HAS NO HISTORY OF RACING OR EVEN HEAVY USE, IS ONLY A DAILY DRIVER ON A SHORT (3 MI.) COMMUTE.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 Mini Cooper S Countryman verdict →
