WHILE PROCEEDING DOWN A NORMAL DRY ROAD I MANUALLY SHIFTED THE TRANSMISSION (USING MANUAL MODE ON THE CVT AUTOMATIC TRANSMISSION) FROM 3RD GEAR TO 4TH GEAR. THE SHIFT NORMALLY WOULD BE SMOOTH HOWEVER ON THIS OCCURRENCE THE ENGINE IDLED EXTREMELY HIGH AND THE GEAR KICKED IN AFTER A COUPLE OF SECONDS WITH A LOUD BANGING SOUND WHEN THE GEAR FINALLY TOOK HOLD. THE CAR BEHAVED ITSELF FOR A WHILE BUT THIS EVENT STARTED HAPPENING MORE AND MORE UNTIL IT BECAME A REGULAR OCCURRENCE. MOST OF THE TIME THERE WAS NO LOUD NOISE BUT THE 4TH GEAR WOULD NOT CATCH AND I ADJUSTED MY DRIVING SO THAT I WOULD SHIFT FROM 3RD GEAR TO 5TH GEAR AS QUICKLY AS POSSIBLE TO AVOID THE OVER REVVING. I BROUGHT THE CAR IN TO A LOCAL TRANSMISSION SHOP. THEY LOOKED IT OVER AND ADVISED ME THAT THERE WAS NO WAY OF REPAIRING THE TRANSMISSION AND THAT I WOULD HAVE TO REPLACE IT ENTIRELY. I AM CURRENTLY WORKING TO LOCATE A NEW TRANSMISSION AS DURING THE LAST OCCURRENCE (JULY 21, 2012) THE CAR DID NOT GO INTO 4TH GEAR AND I WAS STUCK ON A HIGHWAY WITHOUT BEING ABLE TO MOVE, I.E. THE CAR WOULD NOT GO INTO ANY GEAR. AFTER PULLING OVER TO SAFETY I WAS ABLE TO PUT THE CAR UP TO 3RD GEAR AND RETURN HOME. THE CAR IS CURRENTLY UNUSABLE. I AM NOT WORKING WITH THE MANUFACTURER / DEALER AS PREVIOUS EXPERIENCE HAS SHOWN ME THAT THEY ARE EXTREMELY EXPENSIVE AND FINANCIAL GAIN IS THERE PRIMARY OBJECTIVE. IN ADDITION ALL THE INTERNET BLOGS THAT I HAVE REVIEWED, AND JOINED / COMMENTED ON HAS SHOWN ME THAT BMW / MINI DOES NOT WORK WITH THEIR CUSTOMERS TO RECTIFY THIS BAD, UNSAFE PRODUCT. I AM HOPING THAT BMW / MINI WILL WORK WITH THEIR CUSTOMERS WHO ARE STUCK WITH HIS BAD PRODUCT AND I AM ON A LIST TO SUPPORT A CLASS ACTION SUIT AGAINST THEM. *TR

AIR BAG LIGHT KEEPS COMING ON DUE TO FAULTY OC SENSORS, AND FAULTY OC SENSOR CONNECTORS. MINI USA REFUSED EXTENDED WARRANTY ON SENSOR, OR RECALL WHILE PASSENGER SAFETY IS IN JEOPARDY. THE PASSENGER SIDE AIR BAG WARNING INDICATOR ILLUMINATED UNTIL THE ENGINE WAS TURNED OFF. THE FAILURE OCCURRED WHENEVER THE ENGINE WAS IN OPERATION. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THE FRONT PASSENGER SEAT SENSOR PAD WAS FAULTY AND WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM IN WHICH THERE WAS NO RESOLUTION. THE APPROXIMATE FAILURE MILEAGE WAS 35,000. I BELIEVE THIS IS A SAFETY RELATED ISSUE THAT SHOULD BE ADDRESSED BY THE DEALER AS A WARRANTY ISSUE AS I AM NOT COMFORTABLE WITH THE CURRENT SITUATION BUT DO NOT WANT TO PAY FOR AN EXPENSIVE SAFETY RELATED DEFECT. I AM THE ORIGINAL OWNER OF THE VEHICLE AND STILL HAVE IT. PART FAILED IS A SEAT SENSOR. DEALER WANTS CLOSE TO $2K TO REPLACE IT, BUT IT FAILED A LONG, LONG, LONG TIME AGO. I WOULD THINK IT SHOULD LAST LONGER THAN 2 OR 3 YEARS. CAN FIND TONS OF THE SAME PROBLEMS AT HTTP://WWW.NORTHAMERICANMOTORING.COM/FORUMS/STOCK-PROBLEMS-ISSUES-9-2.HTML *JB

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
