2005 MINI COOPER S - ENGINE FIRE A FEW DAYS AGO (7/27/2011) MY 2005 MINI COOPER S CAUGHT FIRE IN THE LOWER REAR ENGINE COMPARTMENT WHILE PARKED IN A BUSINESS PARKING LOT. IT HAD BEEN DRIVEN A SHORT DISTANCE (ABOUT 6 MILES) THREE HOURS PRIOR WITH NO INDICATION OF A PROBLEM. THE CAR IGNITION WAS OFF AND THERE WAS NO KEY PRESENT IN OR NEAR THE VEHICLE. FORTUNATELY, A CO-WORKER SPOTTED THE CAR BILLOWING SMOKE FROM BENEATH THE HOOD AND WE WERE ABLE TO QUICKLY EXTINGUISH THE FIRE BEFORE ANY SIGNIFICANT DAMAGE WAS DONE TO THE VEHICLE OR SURROUNDING PROPERTY. ACCORDING TO THE MECHANIC WHO DIAGNOSED THE CAR AND SUBSEQUENT ELECTRICAL FIRE - THE INCIDENT WAS CAUSED BY AN OVERHEATING AND EVENTUAL IGNITION OF AN ELECTRICAL HARNESS CAUSED BY A SUDDEN FAILURE OF THE POWER STEERING PUMP. I MUST EMPHASIZE THAT PRIOR TO THE FIRE, THERE WAS NO INDICATION IN THE VEHICLE (WARNING SYSTEM) OR BY THE VEHICLES PERFORMANCE THAT THERE WAS ANY PROBLEM WITH THE PUMP OR HANDLING. IT FAILED COMPLETELY WITHOUT WARNING! WHILE PARKED AND UNATTENDED! THANKFULLY, THE CAR WAS NOT PARKED IN MY GARAGE AT NIGHT WHERE THE FIRE WOULD HAVE CERTAINLY GOTTEN A LOT WORSE BEFORE BEING DISCOVERED AND COULD HAVE POTENTIALLY BEEN DEVASTATING TO MY PROPERTY AND FAMILY. AS IT STANDS THE CAR IS SCHEDULED TO BE REPAIRED AT A COST OF NEARLY 1000.00, POSSIBLY MORE AS WE DO NOT YET KNOW IF THERE WAS ANY DAMAGE CAUSED TO ADDITIONAL COMPONENTS WITHIN THE VEHICLE BY THE PUMPS FAILURE. I AM THE ORIGINAL OWNER AND ONLY DRIVER OF THIS VEHICLE. THIS CAR HAS BEEN REGULARLY MAINTAINED AND WAS RECENTLY MECHANICALLY INSPECTED LAST MARCH. NO ISSUES WERE FOUND WITH THE VEHICLE AT THE TIME OF IT'S LAST MAINTENANCE AND INSPECTION. *KB

I HAVE A JANUARY 2005 BUILT MINI COOPER S (R53) WITH APPROXIMATELY 21,000 MILES ON IT. ON FEBRUARY 12, 2011 I WAS DRIVING THE CAR ON A WINDING ROAD IN SOUTHERN CALIFORNIA WHEN THE POWER STEERING PUMP CATASTROPHICALLY FAILED WITHOUT ANY WARNING IN THE MIDDLE OF A HIGH SPEED TURN. THE UNEXPECTED POWER STEERING PUMP FAILURE MADE THE STEERING COMPLETELY UNRESPONSIVE CAUSING THE CAR TO SPIN OUT OF CONTROL AND NEARLY HIT A TREE (I WAS VERY LUCKY THAT I WASN'T KILLED!). AFTER DOING SOME RESEARCH, IT APPEARS THAT UNWARRANTED POWER STEERING PUMP FAILURES ARE QUITE COMMON WITH THE EARLIER MINI COOPER MODELS. I FEEL THAT THIS IS A HUGE SAFETY CONCERN THAT SHOULD BE ADDRESSED BY THE MANUFACTURE VIA A MANDATORY SAFETY RECALL. AFTER THE INITIAL CATASTROPHIC FAILURE OF THE POWER STEERING PUMP, THE PUMP WOULD WORK INTERMITTENTLY IN THAT IT WOULD RUN FINE FOR A WHILE AND THEN FAIL AGAIN WITHOUT WARNING A SHORT TIME LATER MAKING THE CAR EXTREMELY DANGEROUS TO DRIVE. AT TIMES, THE ELECTRIC POWER STEERING PUMP WOULD NOT SWITCH OFF AFTER TURNING OFF THE CAR'S IGNITION AND THE CAR'S BATTERY WOULD ULTIMATELY GO FLAT LEAVING US STRANDED. WE TOOK THE CAR INTO THE MINI DEALERSHIP ON 2/17//2011 AND THEY DIAGNOSED THE CAR AS HAVING A BAD BATTERY (CLAIMING THAT THE BATTERY WAS SO LOW THAT THE CAR WAS ACTUALLY SHUTTING DOWN THE POWER STEERING IN ORDER TO STAY RUNNING). THEY CHARGED US $160 FOR THE DIAGNOSTICS. WE THEN REPLACED THE BATTERY WITH AN OEM BATTER FROM THE DEALERSHIP ($130) AND IT DIDN'T MAKE ANY DIFFERENCE. WE ALSO CONTACTED THE MANUFACTURER (MINI USA) DIRECTLY AND THEY WERE UNWILLING TO HELP CLAIMING THAT THE CAR WAS NO LONGER UNDER THE MANUFACTURER'S WARRANTY. ULTIMATELY, ON JULY 26, 2011 (AT 21,385 MILES) WE REPLACED THE FAILED POWER STEERING PUMP (PART # 32-41-6-778-425) AT A COST OF $735.29 (PLUS LABOR). THE MINI DEALERSHIP WANTED WELL OVER $1,000 TO PERFORM THE WORK AND SO WE PURCHASE A REMPLACEMENT PUMP FROM THE MINI DEALERSHIP AND HAD IT INSTALLED OURSELVES. *TR

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
