TRANSMISSION PREVIOUSLY REPLACED AT 48K MILES BY MANUFACTURER DUE TO NOISE. MY TRANSMISSION IS BROKEN. MY TIRES CHIRP EVERY TIME I PUSH ON THE GAS BECAUSE THE TRANSMISSION DOES NOT KNOW WHAT GEAR TO BE IN DUE TO THE BAD BODY CONTROL VALVE. THE TRANSMISSION NEEDS TO BE REPLACED BECAUSE I CANNOT VERIFY HOW MUCH MECHANICAL DAMAGE HAS TAKEN PLACE DURING THE TIME THAT THE VALVE BODY HAS BEEN BROKEN. ONCE THE VALVE BODY BREAKS DOWN, THE MECHANICAL UNIT ALSO BEGINS TO BREAK DOWN. MINI NEEDS TO ISSUE A SERVICE BULLETIN TELLING THE DEALERS TO COMMENCE SERVICING THE AISIN TRANSMISSIONS EVERY 40K BY REPLACING THE FLUID. BMW/MINI'S TRANSMISSION FLUID IS NOT LIFETIME. VOLKSWAGEN ISSUED A SIMILAR BULLETIN A FEW YEARS AGO BECAUSE IT ALSO USES THE AISIN TRANSMISSION. THE INDEPENDENT REPAIR SHOPS MAY NOT REPLACE THE FLUID RIGHT BECAUSE THE TRANSMISSION FLUID IS HARD TO DRAIN AND IN MANY CASES IF IT'S NOT DONE RIGHT, GREAT DAMAGE IS DONE THE ENGINE. THE CONSUMER STATED THE VEHICLE WAS UNDER POWERED UPON ACCELERATION. THE VEHICLE WOULD JERK, AND BUCK. THE VALVE BODY IN THE TRANSMISSION BEGAN TO BREAK DOWN BECAUSE THE SHAVINGS FROM THE TRANSMISSION GEARS BEGAN TO CLOUD THE FLUID AND INHIBIT COMMUNICATION FROM THE VALVE BODY SOLENOIDS TO THE MECHANICAL COMPONENTS.

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
DEFECTIVE CVT TRANSMISSION! THE DEALERSHIP SAID THAT IT WAS NO FAULT OF OURS THAT WE NEEDED A NEW TRANSMISSION, BUT DUE TO THE WAY THIS TRANSMISSION WAS DESIGNED!!!!!!!! *TR

IN THE EARLY FALL, SEPTEMBER 2011, I ENCOUNTERED ISSUES WITH MY CAR NOT SHIFTING PROPERLY. IT'S AN AUTOMATIC TRANSMISSION SO I KNOW THERE WAS NOTHING I COULD BE DOING TO CAUSE THIS PROBLEM. THE CAR HAS BEEN SERVICED REGULARLY AND DRIVEN WITH CARE WHILE IN MY POSSESSION(I'M THE SECOND OWNER. NO SIMILAR ISSUES ON CARFAX REPORT). WHILE THE ENGINE IS COOL AND NOT YET AT ITS OPTIMAL TEMPERATURE THE DRIVE IS FINE AND YOU MAY NOT EVEN NOTICE A PROBLEM; HOWEVER, EVERY RIDE, ONCE WARMED UP THE CAR BEGINS TO SHIFT INCREDIBLY VIOLENTLY AS IT IS OBVIOUSLY STRUGGLING TO SWITCH GEARS. THIS OCCURS ALSO WHILE SLOWING DOWN AND THE CAR IS DOWNSHIFTING CREATING AN OPPORTUNITY TO BE "SLUNG" INTO A CAR FROM BEHIND(THIS HAPPENED IN THE MID SUMMER OF 2011). AFTER DROPPING THIS CAR OFF SEPTEMBER 15TH TO THE LOCAL MINI DEALERSHIP, I DID NOT HEAR FROM THEM FOR ALMOST THREE WEEKS. IN THE FIRST WEEK OF OCTOBER I WAS CONTACTED AND TOLD IT LOOKS LIKE MY CAR IS VERY EASILY FIXABLE AND SHOULD BE READY SHORTLY. IT WAS EXPLAINED TO ME THAT A SEAL HAD BROKEN ON THE TRANSMISSION LEAKING FLUID ONTO IT CAUSING THIS SHIFTING MALFUNCTION. WHEN THEY FINALLY TOLD ME I CAN PICK UP MY CAR(APPROXIMATELY OCTOBER 18TH) THEY REGRETTED TO INFORM ME THE PROBLEM WAS NOT ABLE TO BE FIXED AND I WOULD HAVE TO BRING IT ELSEWHERE AS THEY DO NOT REBUILD TRANSMISSIONS. NOW IT IS BACK IN MY POSSESSION WHERE I AM FORCED TO COMMUTE IN IT DAILY, DRIVING WORSE THAN IT WAS BEFORE I DROPPED IT OFF. IT NOW DISPLAYS "PE" FOR ITS CURRENT GEAR FROM TIME TO TIME. THIS IS NOT THE ONLY COMPLAINT I HAVE FILED FOR THIS CAR MATCHING OTHER CONSUMER COMPLAINTS. I AM A VICTIM OF THEIR FAILED POWER STEERING AS WELL. *TR

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
