I HAVE HAD THE STEERING PUMP FAIL TWICE IN MY 2005 R53 MINI, THE 1ST TIME THE POWER STEERING WOULD CUT OUT AT RANDOM WHILE DRIVING AND THE PUMP WOULD CONTINUED TO RUN AFTER CAR WAS TURNED OFF (HAD TO DISCONNECT BATTERY FOR IT TO STOP). THIS WAS REPLACED IN 2013 AT A MINI DEALERSHIP UNDER AN "EXTENDED WARRANTY" AT THE EXPENSE OF MINI. NOW 3 YEARS LATER I AM HAVING THE SAME SYMPTOMS, THE POWER STEERING CUT OUT ON WHILE CHANGING LANES ON THE HIGHWAY AND THEN THE PUMP CONTINUED TO RUN WHEN I ARRIVED HOME AND TURNED THE CAR OFF (HAD TO DISCONNECT BATTERY). THE NEXT DAY THE STEERING PUMP ACTUALLY BURNT ITSELF OUT (SMOKED) WHILE THE CAR WAS IDLING IN THE DRIVEWAY. I UNDERSTAND MINI HAS ISSUED A MORE EXTENSIVE RECALL HOWEVER SINCE MINE WAS "FIXED" ALREADY I AM NOT COVERED - IT SEEMS AS THOUGH THE REPLACEMENT PARTS ARE JUST AS FAULTY AS THOSE THEY HAVE REPLACED AND WILL MOST LIKELY EXPERIENCE THE SAME DANGEROUS FAILURE. *TR

THERE IS A POWER STEERING PUMP RECALL FOR THIS MODEL (NHTSA CAMPAIGN NUMBER: 15V660000) BUT THE DATE CUTOFF IS FOR CARS PRODUCED BY FEBRUARY OF THE 2005 MODEL YEAR. MY CAR (2005 MINI COOPER S WITH 86,000 MILES) HAS A PRODUCTION DATE OF JUNE 2005 AND IS NOT ELIGIBLE FOR THE RECALL. THE POWER STEERING PUMP HAS FAILED MAKING STEERING DIFFICULT AND MORE ERRATIC. STEERING NOW REQUIRES SUBSTANTIALLY MORE FORCE, SO MY WIFE IS CURRENTLY UNABLE TO DRIVE THE CAR WITHOUT CONCERNS FOR HER OWN SAFETY. IF THE MANUFACTURER FEELS THAT THE PART THEY USED AFTER FEBRUARY 2005 WAS NOT SUBJECT TO THIS "GLITCH", THEN WHY IS THE PART MALFUNCTIONING IN THE SAME MANNER AS THE ADMITTEDLY FAULTY PART?

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
