“The contact owns a 2003 Mini Cooper. The contact stated that while operating the vehicle, the steering wheel was difficult to turn in either direction. The contact stated that the steering wheel malfunctioned, making the steering wheel easy to turn, causing severe oversteer while making a turn in either direction. The contact stated that the failure was due to a faulty power steering pump, and installed as part of the NHTSA Campaign Number: 15V660000 (STEERING). The vehicle was not repaired. The contact stated that after turning off the vehicle, the power steering pump remained running, causing the battery to drain. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure but no assistance was offered. The failure mileage was 230,000.”

“DRAIN HOSE FROM SUNROOF DRAIN RUNNING DOWN A-PILLAR CAME DISLODGED THROUGH "NORMAL WEAR AND TEAR" CAUSING MASSIVE FLOODING TO THE INTERIOR OF MY CAR. IT WAS RENDERED UNSERVICEABLE AND TOTALED, ON JUNE 16, 2014, BUT UNCOVERED BY INSURANCE. THIS WAS NOTHING THAT I WAS AWARE OF THAT WAS AN ISSUE, NOR WERE ANY RECALLS EVER ISSUED ON THIS ISSUE. I HAD IT IN TO THE DEALERSHIP IN 2012, 2 YEARS AGO, FOR ELECTRICAL FAILURE, AND THEY THOUGHT IT WAS MERELY THE BATTERY, SO THEY REPLACED IT AND IT SEEMED TO BE FINE, BUT THEY SAID TO KEEP THE BATTERY AS A BACK UP "JUST IN CASE" BECAUSE IT STILL APPEARED TO BE A GOOD BATTERY. THEN LATER IN 2013, I TOOK IT BACK TO THE MINI DEALER FOR GENERAL SERVICE AND I SAID I NOTICED WATER IN THE BOOT (TRUNK) AND FOR THEM TO CHECK THE HATCHBACK SEAL TO SEE IF THERE WAS ANY LEAKS, THEY SAID NO, AND NO FURTHER INVESTIGATION WAS DONE FOR EITHER EVENT. I BELIEVE THAT BOTH THESE EVENTS WERE RESULTS OF THE FAULTY DRAIN HOSE FROM THE A-PILLAR BEING DISLODGED FOR SO LONG. TODAY, THE AUTOMOBILE LEFT MY POSSESSION, TO AN AUCTION HOUSE. I WANTED TO FILE THIS COMPLAINT SO THAT YOU, THE NHTSA CAN PERHAPS HAVE MINI ISSUE A RECALL TO FIX THIS ISSUE AND…”
