LOSS OF POWER WHEN GOING 60 MPH IN THE HIGH SPEED LEFT LANE OF FOUR LANE HIGHWAY. CAR WENT INTO "LIMP MODE" AND UNABLE TO ACCELERATE. CAR WOULD ONLY GO 5 TO 10 MPH WITH LARGE TRUCK BEHIND AND BEARING DOWN ON ME. EML AND SERVICE ENGINE LIGHTS ON DASH. WAS ABLE TO PULL INTO A CONSTRUCTION LANE THAT HAPPENED TO BE RIGHT THERE. OTHERWISE WOULD HAVE BEEN UNABLE TO GET CAR OUT OF THE WAY. CAR NEEDED TO BE TOWED. FAULT CODES LIST THROTTLE BODY AND WIRING HARNESS AS PROBLEMS AND RECOMMENDATION IS TO REPLACE BOTH. FROM MY RESEARCH, THE PROBLEM IS WELL KNOWN AND RELATES TO POOR CONNECTOR BETWEEN THROTTLE BODY AND WIRING HARNESS. MINI HAS SINCE REDESIGNED THE ANGLE OF THIS CONNECTOR TO FIX THIS PROBLEM. SUCH A LOSS OF POWER WHILE DRIVING IS EXTREMELY DANGEROUS. SHOULD BE RECALL ITEM. *TR

A FIRE WAS CAUSED BY THE FAILURE OF THE POWER STEERING COOLING FAN. AT SOME POINT THE DAY OF THE INCIDENT THE FAN SEIZED AND THE RESULTING ELECTRICAL RESISTANCE IN THE MAIN WIRING HARNESS CAUSED THE WIRING HARNESS TO HEAT TO A POINT OF MELTING SOME OF THE PLASTIC WIRE INSULATION ALLOWING FOR DIRECT WIRE TO WIRE CONTACT AND RESULTED IN AN ELECTRICAL FIRE BETWEEN THE ENGINE AND THE PASSENGER COMPARTMENT. THE RESULTING FIRE COMPLETELY DISABLED THE VEHICLE'S ELECTRICAL SYSTEM AND REQUIRES AT MINIMUM THE REPLACEMENT OF THE ENTIRE MAIN WIRING HARNESS. EVENT DESCRIPTION AFTER A SHORT DRIVE (LESS THAN 2 MILES ON A COLD ENGINE) THE VEHICLE WAS PARKED. AFTER THE ENGINE WAS TURNED OFF SMOKE WAS SEEN RISING FROM THE VEHICLE ENGINE COMPARTMENT. UPON RAISING THE HOOD, FLAMES WERE SEEN BETWEEN THE ENGINE AND THE PASSENGER COMPARTMENT REFLECTING OFF BOTH FIRE WALLS. 2 FIRE EXTINGUISHERS WERE REQUIRED TO PUT OUT THE FLAMES AFTER THE BATTERY WAS DISCONNECTED. TOTAL LOSS OF THE VEHICLE TO FIRE WAS PREVENTED BY THE OWNERS ACTIONS.

WHEN THIS HAPPENED ON A HIGHWAY THERE WAS NOT ENOUGH POWER TO REMOVE THE CAR FROM THE ROAD SAFELY. AFTER SEVERAL INEFFECTUAL REPAIRS, THE WIRING HARNESS WAS REPLACED. SHORTLY AFTER THE REPAIR, THE CAR WAS PARKED, EMERGENCY BRAKE SET, MANUAL TRANSMISSION SET IN FIRST GEAR. UNATTENDED, TURNED OFF WITH NO KEY IN THE IGNITION, THE CAR MOVED ITSELF SEVERAL FEET, HITTING ANOTHER CAR, BURNING OUT THE STARTER AND DRAINING THE BATTERY. THE CAR WAS MOVED TO A REPAIR SHOP WHERE THE STARTER WAS REPLACED. OVERNIGHT, WITH THE CAR PARKING INSIDE THE LOCKED SHOP, THE CAR MOVED ITSELF ACROSS THE SHOP.

TOOK MY CAR IN FOR WINDING SOUND COMING FROM MOTOR. DIAGNOSED AS THE ALTERNATOR...THEY REPLACED IT AND SOUND WAS STILL PRESENT ...MISDIAGNOSED AND WAS ACTUALLY THE SUPERCHARGER, BUT WHILE THEY WERE CHECKING IT OUT INITIALLY THE POWER STEERING PUMP STAYED ON...WHICH DIDN'T HAPPEN TO ME UNTIL THEY HAD IT. AFTER CHANGING THE ALTERNATOR POWER STEERING PUMP NO LONGER STAYED ON PER THE DEALER. HAD IT HOME 3 DAYS TO WAKE UP ONE MORNING HEARING THE PUMP ON AND I GO TO START MY CAR AND IN DRAINED MY BATTERY. HAD TO JUMP THE CAR AND THEN DISCONNECT THE CABLE TO KEEP FROM THE PS PUMP CONTINUOUSLY RUNNING. THE CAR IS AT THE DEALER GETTING A NEW PUMP $975 PLUS TAX, RESEARCHED MINI OWNER WEBSITE AND FOUND SEVERAL COMPLAINTS OF THE SAME ISSUE ALSO THAT SOME CARS ACTUALLY CAUGHT FIRE FROM A FAILURE OF THE PUMP. RESEARCHED MORE ON NORTH AMERICAN MOTORING . THERE WAS A LONG LIST OF PEOPLE WHO HAD THE EXACT EXPERIENCE. SURE WOULD BE AWFUL FOR THE PUMP TO GO OUT WHILE DRIVING ON EXPRESSWAY AND NOT ABLE TO STEER CORRECTLY. SURPRISED IT HASN'T CAUSED AN ACCIDENT/DEATH YET. *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

ALTHOUGH SOME OF THE REPORTS ALLEGING FIRES NOTE SMALL FLAMES WERE VISIBLE IN THE ENGINE COMPARTMENT, ANALYSIS OF THE DAMAGE CAUSED BY THESE FAILURES INDICATES THAT EVEN THE MOST SEVERE INCIDENTS WERE LIMITED TO LOCALIZED THERMAL DAMAGE TO THE EHPS ELECTRICAL CONNECTIONS AND WIRING INSULATION.NONE OF THE COMPLAINTS ALLEGING LOSS OF POWER ASSISTED STEERING INDICATED THAT THE INCREASED EFFORT RESULTED IN A CRASH OR LOSS OF VEHICLE CONTROL. A SAFETY-RELATED DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED. ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.
