I BOUGHT A 2005 MINI COOPER IN SEPT 09 WITH 61,450 MILES. SEVERAL MONTHS LATER THE STEERING "CUT OUT" AS I TURNED A CORNER. I TOOK IT TO OUR MECHANIC WHO COULDN'T FIND ANYTHING WRONG & SAID THAT IT MAY JUST BE THAT A SPECK OF DIRT THAT GOT INTO THE SYSTEM. IT HAPPENED A COUPLE MORE TIMES AND I ASSUMED THAT THE "DIRT" WAS WORKING ITS WAY OUT. THEN I HAD A DRAMATIC INCIDENT WHERE NOT ONLY DID THE STEERING SUDDENLY AND UNEXPECTEDLY CUT OUT, BUT THERE WAS TREMENDOUS "DRAG" ON THE SYSTEM AND IT TOOK ALL MY MIGHT & MAIN TO TURN THE STEERING WHEEL. TRYING TO MAKE A RIGHT TURN I FOUND MYSELF IN THE OPPOSITE LANE. I TOOK THE CAR BACK TO THE MECHANIC WHO EVENTUALLY GOT THE CAR TO FAIL FOR HIM. HE TOLD ME TO GO TO A MINI SERVICE CENTER WHO COULD DEAL WITH THE FAULTY ELECTRONICS. I CALLED MINI OF AMERICA TO ASK FOR ASSISTANCE IN MAKING THE CAR "RIGHT" BUT I WAS TOLD THAT CARS BREAK, THAT IT IS BEYOND THE 50,000 WARRANTY AND THAT IF THE CAR WAS UNSAFE, I SHOULD HAVE IT FIXED. THE REP SAID THAT "MAYBE" THEY WOULD PAY FOR PART OF THE PROBLEM AFTER IT WAS DIAGNOSED. I THEN SPOKE WITH A MECHANIC AT A MINI SERVICE CENTER WHO KNEW IMMEDIATELY WHAT WAS WRONG. HE SAID THIS IS A COMMON PROBLEM WITH MINIS BEFORE 2007 ----FIRST THE PROBLEM IS INTERMITTENT, THEN THE ELECTRONICS COMPLETELY FAIL. PAYING FOR MAINTENANCE AND REPAIRS FOR A CAR THAT I OWN IS MY RESPONSIBILITY BUT I BELIEVE THAT A CAR MANUFACTURER IS OBLIGATED TO PUT OUT A SAFE CAR. IF THIS IS A DESIGN ERROR, THEN THE COMPANY SHOULD MAKE IT RIGHT. WHEN I TURN THE WHEEL, I NEED TO TRUST THE ELECTRONICS TO RESPOND -- BECAUSE MY LIFE AND THE LIVES OF MY PASSENGERS DEPENDS ON IT. I THINK THAT MINI SHOULD BE REQUIRED TO INSURE THAT THE COMPUTER THAT GOVERNS STEERING OPERATES PROPERLY. AT PRESENT I HAVE A CAR THAT SITS DRIVEWAY BECAUSE IT IS TOO DANGEROUS TO DRIVE. I AM MAKING A TRIP TO A CITY THAT HAS A SERVICE CENTER IN TWO WEEKS AND I AM HOPING THAT MINI CORRECTS THIS PROBLEM WITH NO EXPENSE TO ME. *TR

AFTER A COUPLE MINUTES OF INVESTIGATING IN THE HOUSE, I DECIDED TO GO BACK INTO THE GARAGE, AND FIND THAT IT IS A LITTLE SMOKEY. I OPEN THE GARAGE DOOR AND BACK THE MINI OUT ONTO THE DRIVEWAY. NOW THERE IS SMOKE STREAMING FROM UNDER THE HOOD. I CAN HEAR SPINNING/CLICKING NOISES COMING FROM THE ENGINE COMPARTMENT. I OPEN THE HOOD AND SEE FLAMES COMING OUT OF THE BACK OF THE ENGINE, BELOW THE EXHAUST MANIFOLD. I EMPTIED 3 FIRE EXTINGUISHERS INTO THE ENGINE BAY AND IT WAS STILL BURNING. CALLED 911.

215V660000 · Steering:electric Power Assist System
Oct 15, 2015
BMW of North America, LLC (BMW) is recalling certain model year 2002-2005 MINI Cooper and Cooper S vehicles and 2005 Cooper and Cooper S Convertible vehicles. The affected vehicles may experience temporary or permanent loss of the electro-hydraulic steering assistance.
Consequence & remedy
Consequence: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, potentially increasing the risk of a vehicle crash.
Remedy: MINI will notify owners, and dealers will inspect the electro-hydraulic power steering system, replacing the components and wiring, as necessary, free of charge. Interim notices were mailed to owners on December 10, 2015. Owners will receive a second notice when remedy parts become available. Owners may contact MINI customer service at 1-866-825-1525.
15V205000 · Air Bags:frontal
Apr 6, 2015
BMW of North America, LLC (BMW) is recalling certain model year 2005-2006 MINI Cooper and Cooper S vehicles manufactured January 5, 2005, to November 28, 2006, and 2005-2008 MINI Cooper Convertible and Cooper S Convertible vehicles manufactured January 5, 2005, to July 31, 2008. Due to manufacturing, installation, and exposure issues, the front passenger seat occupant detection mat may not function properly and, as a result, the front passenger air bag may not deploy in a crash.
Consequence & remedy
Consequence: An improperly functioning mat may cause the passenger frontal air bag to be inactive when the seat is occupied, and in the event of a crash, the air bag will not deploy, increasing the passenger's risk of injury.
Remedy: MINI will notify owners, and dealers will replace the front passenger seat occupant detection mat, free of charge. The recall began on October 12, 2015. Owners may contact MINI customer service at 1-866-825-1525.

The Office of Defects Investigation (ODI) originally opened the investigation of loss of power steering assist in model year (MY) 2004 and 2005 Mini Cooper as Preliminary Evaluation PE10-038.The investigation was upgraded to Engineering Analysis EA11-005 in May, 2011.During EA11-005 the scope was expanded to include MY 2002 and 2003 vehicles that use the same steering system.The subject vehicles now include MY 2002, the first year BMW sold MINI in the U.S., through mid-MY 2005 covering approximately 109,000 vehicles.The subject vehicles use an electrically driven pump to provide hydraulic pressure to a conventional rack-and-pinion steering gear.A pump, the electric motor, and an electronic control unit (ECU) are housed in a single component BMW calls a Power Pack.The investigation focused on contaminant-induced failure of the ECU resulting in a loss of assist without warning.When assist is lost mechanical steering is retained however increased steering effort is required to keep the vehicle on an intended path.Some consumers reported that restarting the vehicle (cycling the ignition switch) would often reinstate the steering assist.Additionally, and by design, assist can also reinstate during the drive cycle in limited circumstances.The unexpected loss of assist, and/or possibly the reinstatement of assist while driving, may contribute to a loss of vehicle control in certain driving situations.During MY 2005 production BMW introduced a revised Power Pack design (the ECU incorporated a conformal coating of the circuit board) which resulted in a significant reduction in failures.ODI identified 20 reports describing crashes consistent with a loss of power assist event possibly caused by a failure of the Power Pack.Two reports alleged an injury however both were minor in nature and did not require emergency treatment (a subsequent doctor's visit occurred in one case).Ten of these reports described low speed crashes with minimal, or in most cases no property or vehicle damage (e.g., striking a movable barrier in a parking lot).Additionally 27 other reports alleged or indicated that a crash occurred due to a Power Pack failure however in reviewing these reports, ODI either 1) was unable to confirm that a crash actually occurred (8 reports), or 2) determined that the crash circumstances (e.g., adverse road/weather conditions) or cause (e.g., the crash was caused by steering linkage failure) were not attributable to a Power Pack failure (19 reports).Throughout the investigation BMW maintained that loss of assist in the subject vehicles did not constitute a safety related defect, noting that the subject vehicles are smaller, light weight vehicles that can be reasonably controlled when assist is lost.In May 2013 BMW launched a 13 year/150,000 mile extended warranty coverage utilizing the redesigned Power Pack as a replacement part.ODI continued its investigation.In July 2014 BMW provided ODI a status of the ongoing extended warranty program, and in May 2015 ODI requested an update of complaint data.Following a review of the provided data, ODI informed BMW of its assessment that loss of steering assist failures were not adequately resolved by an extended warranty program.On October 12, 2015 BMW notified NHTSA that it would conduct a safety recall (15V-660) on approximately 86,000 subject vehicles not previously remedied with the new design Power Pack through regular or extended warranty programs.The recall covers MY 2002-2005 MINI Cooper, MY 2002-2005 MINI Cooper S, and MY 2005 MINI Cooper/Cooper S convertibles manufactured through Feb 9, 2005.Vehicles produced after this date are not included si
