I PURCHASED A USED MINI COOPER S SIX MONTHS AGO, IN DECEMBER 2011. I DROVE MY VEHICLE AS I NORMALLY DUE, JUST ACROSS TOWN ABOUT 10 MILES, AND IT WAS FINE. I PARKED MY CAR AND WENT INSIDE. WHEN I CAME OUT, ABOUT 10-15 MINUTES LATER, AND TRIED TO BACK OUT OF THE DRIVEWAY, THE POWER STEERING WAS NON-EXISTENT. I PULLED BACK INTO THE DRIVEWAY AND CHECKED THE FLUID LEVEL AND LET THE CAR COOL DOWN FOR A FEW MORE MINUTES. WHEN I RESTARTED THE CAR, THE POWER STEERING WAS BACK. SINCE THEN, THE POWER STEERING IS INTERMITTENT. IF THE CAR IS HOT, IT USUALLY DOES NOT WORK, BUT IF THE CAR IS GIVEN A CHANCE TO COOL DOWN, THEN IT SEEMS TO WORK, BUT THE PROBLEM IS OCCURRING MORE AND MORE FREQUENTLY AND I HAVE FOUND MANY COMPLAINTS FROM OTHER MINI OWNERS. *TR

I DROVE MY 2003 MINI COOPER S TO MY LOCAL DEPARTMENT OF TRANSPORTATION TO RENEW MY DRIVER'S LICENSE. NOTHING ABNORMAL OCCURRED ON THE TRIP TO THE DMV. WHEN I GOT IN AND BEGAN TO DRIVE HOME, THERE WAS NO POWER STEERING. LATER THAT EVENING, I STARTED THE CAR WHEN IT WAS COOL AND THE POWER STEERING WAS BACK UNTIL THE CAR WARMED UP. THE RADIATOR FAN AND THE POWER STEERING FAN DO NOT FUNCTION UPON DOING RESEARCH ON THE INTERNET, I HAVE FOUND THAT THIS PROBLEM OCCURS EXTREMELY OFTEN IN 2002-2007 MINIS. I ALSO FOUND, POSTED ON A MINI FORUM BY SOMEONE CLAIMING TO BE AN ENGINEER, A DIAGNOSIS OF THE PROBLEM. CARBON DUST FROM THE ELECTRIC MOTOR THAT OPERATES THE POWER STEERING PUMP GETS INTO THE CONTROL UNIT ATTACHED TO IT. SINCE THE CHIP WAS NOT PROPERLY SEALED WITH A LACQUER, IT CAUSEES A SHORT CIRCUIT IN THE CHIP. THIS CAUSES THE PUMP TO FAIL. ANOTHER POSSIBLE CAUSE IS THE FAILURE OF THE COOLING FAN FOR THE POWER STEERING PUMP. THE FAN CAN SEIZE, STOP COOLING THE PUMP, AND EVENTUALLY IT WILL OVERHEAT. THIS ALSO TRIPS A FUSE THAT STOPS THE RADIATOR FAN. AS A RESULT, THE ENGINE CAN ALSO OVERHEAT. I HAVE DETERMINED THAT THE FAN HAS STOPPED WORKING. SINCE I HAVE ONLY HAD THIS CAR SINCE THE MIDDLE OF WINTER AND THE HAS BEEN THE ONLY WARM DAY I HAVE DRIVEN IT, THIS WAS THE FIRST TIME I NOTICED IT. I PLAN TO AVOID THE $1000 CHARGE TO HAVE IT REPLACED AT THE DEALER BY REPAIRING IT MYSELF BUT MANY PEOPLE ARE NOT THIS FORTUNATE. I BELIEVE THIS DESIGN FLAW CAN AND WILL CAUSE SERIOUS ACCIDENTS TO OCCUR. IF MY MOTHER, SISTER, OR GIRLFRIEND HAD BEEN DRIVING MY CAR ON THE HIGHWAY WHEN IT FAILED, THEY WOULD NOT HAVE BEEN ABLE TO STEER RESULTING IN A SERIOUS CRASH. WHILE PERUSING VARIOUS MINI FORUMS, I HAVE READ STORIES OF SEVERAL SERIOUS CRASHES. I WOULD LIKE TO SEE A RECALL ON ALL 2002-2007 MINI COOPERS SO THAT THIS PROBLEM CAN NOT HARM SOMEONE.

15V660000 · 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

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.
