OUR MINI COOPER REPEATEDLY STALLED WHILE IN HEAVY TRAFFIC RESULTING IN SEVERAL NEAR DEATH EXPERIENCES. NO FAULT CODE OR CHECK-ENGINE LIGHT EVER APPEARED. UPON TAKING THE CAR INTO THE DEALERSHIP, WHILE UNDER WARRANTY, THE PROBLEM AND OUR CONCERNS WERE DISMISSED WITHOUT REMEDY. FINALLY, AFTER BEING IN THE MOUNTAINS ON WINDY ROADS A CLICKING NOISE BEGAN. SINCE NO FAULT OR CHECK-ENGINE LIGHT APPEARED, WE ASSUMED THE CAUSE OF THE NOISE TO BE FROM SOMETHING MINOR AND OPTED TO DRIVE THE CAR TO THE NEAREST MECHANIC, A FIVE MILE DRIVE. SHORTLY BEFORE ARRIVING TO THE MECHANIC, THE MINI UNEXPECTEDLY BECAME QUITE DIFFICULT TO CONTROL. LUCKILY WE WERE ABLE TO GET OFF THE FREEWAY, UPON WHICH THE TRANSMISSION COMPLETELY STOPPED WORKING ' REQUIRING THE CAR TO BE PUSHED TO THE MECHANIC. AGAIN, NO CHECK-ENGINE LIGHT CAME ON AS A WARNING AND NO FAULT CODES WERE STORED. BMW'S MINI COOPER CVT TRANSMISSION POSES A SIGNIFICANT SAFETY HAZARD TO DRIVERS. RESEARCH INDICATES BMW IS AWARE OF THE DEFECTIVE TRANSMISSION, WHICH EXPLAINS WHY BMW OPTED TO NO LONGER USE THE CVT TRANSMISSION IN LATER MODELS. THANK YOU FOR TAKING THE TIME TO RECTIFY THE SITUATION TO KEEP MINI OWNERS & OTHER DRIVERS SAFE. OURS IS JUST ONE OF MANY SIMILAR EXPERIENCES WE'VE RECENTLY LEARNED OF WHILE RESEARCHING THE DISMAL TRACK RECORD OF BMW'S CVT TRANSMISSIONS IN EARLY MINI COOPERS. *TR

I HAVE A 2003 MINI COOPER WITH AUTOMATIC CVT TRANSMISSION AND HAVE HAD RECURRING PROBLEMS WITH THE CVT SINCE I PURCHASED THE VEHICLE. BELOW IS A SUMMARY OF SERVICE VISITS, REPLACEMENT OF THE CVT IN 2007, AND THE CURRENT STATUS OF THE CVT AS INOPERABLE. I HAVE ALL INVOICES DETAILING WORK DONE. 10/9/02 - I PURCHASED A NEW 2003 MINI COOPER WITH AUTOMATIC CVT TRANSMISSION FROM BARON BMW IN MERRIAM, KS. 12/02 - MINI USA SENT ME LETTER RE: CHASSIS #TE13495 THAT SOME AUTOMATIC CVT TRANSMISSIONS HAD BEEN FILLED WITH THE INCORRECT TRANSMISSION OIL AND TO SCHEDULE AN APPOINTMENT TO HAVE IT FLUSHED AND REPLACED ASAP. 12/27/02 - BARON FLUSHED AND REPLACED FLUID. I ALSO COMPLAINED THAT THE CAR HAD DIED TWO TIMES AND RAN ROUGH. MILEAGE 1,760. 7/2/03-I TOOK MINI IN COMPLAINING "WHEN GOING FROM REVERSE TO DRIVE CAR HAS A HARD LURCH" AND BARON'S INVOICE STATES "TEST DROVE CAR AND FOUND IT WAS VERY HARSH GOING INTO GEAR AND LURCHED WHEN IT WAS COLD". 2ND AUTO TRANS CONCERN WAS "CAR HAS ALMOST DIED AT LOW IDLES A FEW TIMES". BARON REPROGRAMMED THE CAR UNDER WARRANTY. MILEAGE 6,465. 7/23/07-CUSTOMER GOODWILL PROVIDED BY BARON MINI AND REPLACED THE TRANSMISSION AT NO COST ALTHOUGH WARRANTY WAS UP. MILEAGE 49,512. 9/11/07-I TOOK MINI IN AGAIN COMPLAINING OF ROUGH IDLE AND CAR WANTS TO DIE AT STOPS. MILEAGE 51,167. 8/13/09- MINI WAS HAVING A HARD TIME SHIFTING OUT OF 1ST GEAR. IT WOULD ONLY DRIVE 15-20 MPH AT UP TO 3,000 RPMS. I CALLED BARON AND WAS TOLD THE CURRENT TRANSMISSION HAD A TWO YEAR WARRANTY (WHICH MADE THIS COMPLAINT 2 YEARS AND A FEW WEEKS PAST WARRANTY) BUT IT WAS POSSIBLE MINI WOULD COVER REPAIR/REPLACEMENT. THEY DID NOT. BARON FLUSHED AND FILLED THE TRANSMISSION FLUID AND SAID IT RUNS BETTER BUT IT IS NOT FIXED. THEY RECOMMEND REPLACING THE CVT AGAIN. I HAVE NOT HAD THE CVT REPLACED (FOR THE 2ND TIME).

I BOUGHT A 2003 MINI COOPER AND ABOUT A WEEK AND A HALF AGO, THE CLUTCH HYDRAULIC SYSTEM HAS SPRUNG A LEAK. UPON INSPECTION OF THE HYDRAULICS, THE MECHANIC NOTICED THAT THE CLUTCH CONTROL ROD WAS MOVING IN A FUNNY WAY. HE SAYS THAT THEY WILL HAVE TO DROP THE TRANSMISSION TO SEE THE ACTUAL PROBLEM AND THAT REMOVING THE TRANSMISSION ALONE WILL COST ME 1000.00 DOLLARS WHICH I DO NOT HAVE AT THE MOMENT. THE CAR ONLY HAS 67,000 MILES ON IT AND THE CLUTCH WENT WITHOUT ANY WARNING. ALSO, I AM TOLD THAT IF THE CLUTCH DOES NEED TO BE REPLACED, IT WILL COST ME 1800.00 DOLLARS, WHICH AGAIN, I DO NOT HAVE. *TR

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.
03V086000 · Suspension:rear:shock Absorber
Mar 10, 2003
ON CERTAIN VEHICLES, THE LOWER SCREW CONNECTION OF THE REAR STRUTS TO THE CHASSIS MAY FAIL. THE HEAD (TOP) OF THE SCREW SECURING THIS CONNECTION MAY BREAK. THE REMAINING PORTION OF THE SCREW WILL STILL HOLD THE STRUT IN PLACE.
Consequence & remedy
Consequence: IF LEFT UNATTENDED OVER A PERIOD OF TIME, AND DEPENDING ON DRIVING CONDITIONS, THE REMAINING PORTION OF THE SCREW MAY BREAK. IF IT BROKE, THE CHASSIS WOULD LEAN DIRECTLY ON THE TIRE DIMINISHING THE DRIVER'S ABILITY TO CONTROL THE VEHICLE, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE LOWER SCREW CONNECTION OF THE REAR STRUTS. OWNER NOTIFICATION BEGAN APRIL 7, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT BMW AT 1-800-831-1117.

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

THE OFFICE OF DEFECTS INVESTIGATION (ODI) ANALYZED CONSUMER COMPLAINTS TO BMW OF NORTH AMERICA, LLC (BMW)AND TO ODI THAT ALLEGED FAILURES OF THE ELECTROHYDRAULIC POWER STEERING (EHPS) USED IN MODEL YEAR 2002 THROUGH 2003 MINI COOPER VEHICLES.THE ANALYSIS DETERMINED THAT 43 OF THE 52 (83%) REPORTS WERE RELATED TO ALLEGATIONS OF POWER STEERING LOSS AND 9 (17%) WERE RELATED TO ALLEGATIONS OF ENGINE COMPARTMENT FIRES. 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.
