TL* THE CONTACT OWNS A 2005 MINI COOPER. AFTER TURNING THE VEHICLE OFF, THE POWER STEERING PUMP CONTINUED TO OPERATE. ALSO, WHILE OPERATING THE VEHICLE, THE POWER STEERING PUMP SOMETIMES FAILED AND THE STEERING WHEEL BECAME VERY DIFFICULT TO TURN IN EITHER DIRECTION. ALSO, THE LOW BATTERY WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO ORLANDO MINI (350 LAKE DESTINY DRIVE, ORLANDO, FL) WHERE IT WAS DIAGNOSED THAT THE POWER STEERING PUMP WAS FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS ALSO NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 172,000.

THIS IS IN THE DESIGN OF THIS YEAR OF MINI COOPER AS I AM FINDING THAT IT IS ON THE INTERNET AS JUST A BAD DESIGN. I CAN'T GET ANYONE TO WORK ON IT FOR A REASONABLE PRICE.

BEFORE I BOUGHT THE CAR IT WAS REAR-ENDED FROM LOSING SPEED BECAUSE THE TRANSMISSION WAS SLIPPING.

I'M HOPING THERE'S SOME HELP OUT THERE FOR UNSUSPECTING INNOCENT PEOPLE LIKE ME WHO THOUGHT THEY WERE GETTING A GOOD CAR AND NOW IT IS JUST UNSAFE AS I HAVE HAD TO TOW IT 3 TIMES NOW AND I'VE ONLY HAD IT SINCE MAY OF THIS YEAR 2018.
POWER STEERING PUMP FAILED WHILE CAR WAS BEING DRIVEN. VEHICLE ONLY HAS 90K AND FOR SOME REASON WAS NOT COVERED UNDER THE RECALL PER MINI USA. MINI NEEDS TO REVIEW THE RECALL AND CORRECT ALL 2005 MINI COOPER'S WITH THIS DEFECT.
WHILE DRIVING CAR MY STEERING WHEEL BECAME VERY HEAVY AND HARD TO STEER.
STEERING IS DIFFICULT AND REQUIRES EXERTION WHEN I TURN THE WHEEL.

THE POWER STEERING IN MY MINI COOPER 2005 HAS BEEN INTERMITTENT. THE STEERING WHEEL BECOMES VERY HARD TO TURN ALL OF A SUDDEN, PARTICULARLY AT LOW SPEEDS WHEN IT IS NEEDED THE MOST TO MAKE TURNS OR TO PARK. THERE ARE NO FAULT INDICATORS FOR THIS ISSUE ON THE DASHBOARD EITHER. THE VERY FIRST TIME THIS HAPPENED IN MARCH 2011 WHEN MY CAR HAD LESS THAN 80,000 MILES ON IT. THE POWER STEERING BECAME COMPLETELY INOPERABLE. AT THAT TIME THE DEALER INFORMED ME THAT THE POWER STEERING PUMP FAILURE WAS A KNOWN PROBLEM IN MINI COOPER AND THAT THE PUMP HAD TO BE REPLACED. THE REPLACEMENT COST WAS TOO HIGH THOUGH, HENCE I CHOSE TO THINK ABOUT IT BEFORE HAVING IT REPLACED. LUCKILY, THE POWER STEERING STARTED WORKING AGAIN AND EVEN THOUGH STEERING BECAME A LITTLE HARD AT TIMES I GOT USED TO IT. BUT SINCE END OF APRIL 2017 THE PROBLEM HAS BEEN GETTING WORSE. STEERING GETS TOO HARD AT TIMES AND REQUIRES A LOT OF FORCE TO TURN THE STEERING WHEEL AT LOW SPEEDS. GETTING IN AND OUT A COMPACT PARKING SPOT IS EXCEPTIONALLY HARD. MAKING LEFT, RIGHT AND U TURNS ARE ALSO VERY HARD. EVEN THOUGH THERE IS A RECALL ON THIS ISSUE, I HAVE NOT RECEIVED A RECALL NOTICE IN THE MAIL. I DON'T UNDERSTAND WHY MY CAR WAS NOT INCLUDED IN THE RECALL. OR IF THE RECALL IS ONGOING, WHY SHOULD IT TAKE SO LONG SINCE THIS IS A SAFETY ISSUE.
Official recalls
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.

Status: closed (inferred from source dates) · Steering; Steering:electric Power Assist System; Steering:hydraulic Power Assist System; Steering:hydraulic Power Assist:pump
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
