I WAS DRIVING AROUND 40 MILES PER HOUR AND THE CAR ABRUPTLY SLOWED DOWN THEN SPED UP WITHOUT ANY WARNING, IF ANOTHER CAR WAS BEHIND ME, IT WOULD HAVE CAUSED SOME SERIOUS DAMAGE. NOW MY CAR WOULDN'T SHIFT SHIFT OUT OF FIRST GEAR. I WAS TOLD BY MY MECHANIC THAT THE CVT TRANSMISSION IS GONE. AFTER REACHING OUT TO MINI USA, THEY TOLD ME THEY HAVEN'T HAD ANY PROBLEM WITH THIS TRANSMISSION AND IT'S PASS THE WARRANTY DATE. IF THE FOLKS AT MINI USA HAD BEEN HONEST WITH ME I COULD HAVE MADE THE DEADLINE FOR A SETTLEMENT PERTAINING TO THE SAME PROBLEM THEY CLAIMED THEY HAD NO IDEA ABOUT. THIS PRODUCT NEED TO BE RECALLED! AFTER DOING EXTENSIVE RESEARCH THE CVT TRANSMISSION HAVE HAD PROBLEMS ALL ALONG AND THE COMPANY HAVE BEEN SETTLING CLAIMS FOR QUITE SOME TIME. WHY ARE THEY ALLOWED TO RUN HARD WORKING FOLKS INTO DEATH BECAUSE THEY KNOW MOST OF US CAN'T AND WOULDN'T PURSUE THIS MATTER. IT WILL COST ME 6500.00 FOR THE PART AND ANOTHER $2200 FOR LABOR, THE CAR IS NOW VALUED AT $5500.00. IT THERE SOMETHING WRONG WITH THIS?

WE PURCHASED A NEW 2004 MINI-COOPER R50 AND PAID EXTRA FOR INSTALLATION OF A CVT TRANSMISSION. THE CVT ' (SPORT MODE)' FAILED IN 2010, JUST 2 YEARS AFTER ITS WARRANTY EXPIRED AND WITH ONLY 35,147 MILES DRIVEN. WE WERE TOLD THAT IT COULD COST BETWEEN $2,000 AND $9,000 TO REPAIR/REPLACE THE SPORT MODE' FUNCTION, AND SINCE THE AUTOMATIC TRANSMISSION IS STILL OPERATING, WE DECIDED TO AVOID THE UNCERTAINTY OF COSTLY REPAIRS AND MAKE SURE NO ONE ELSE DRIVES THIS VEHICLE. SINCE THEN, WE HAVE LEARNED OF OTHER PREMATURE CVT FAILURES AND THREE CLASS-ACTION LAWSUITS REGARDING THIS TRANSMISSION: AARONS V. BMW OF NORTH AMERICA, LLC [XXX],BONOMO V. BMW[XXX], AND BOURNE-MILLER V. BMW[XXX]. PREMATURE 'SPORT-MODE' FAILURE CAN CAUSE PERMANENT DAMAGE TO A $9,000 TRANSMISSION WITH DEADLY CONSEQUENCES ON U.S. HIGHWAYS AT HIGH SPEEDS. CLASS ACTION LAWSUITS DO NOT ADDRESS THIS PROBLEM, AND WE HAVE 'OPTED-OUT' OF PARTICIPATION IN THEM. PLEASE INVESTIGATE THE EXTENT OF PREMATURE CVT FAILURES IN THE MINI-COOPER AND ISSUE A RECALL APPROPRIATE TO REMEDY THIS POTENTIALLY DEADLY DEFECT. PLEASE LET US KNOW IF MORE INFORMATION OR DOCUMENTATION IS REQUIRED. UNDER PENALTIES OF PERJURY IN THE STATE OF CALIFORNIA I SWEAR THAT THE FORGOING DETAILS ARE ACCURATE AND TRUTHFUL TO THE BEST OF MY ABILITY.

I HAVE A 2004 MINI COOPER IT HAS RECENTLY REACHED 87000 MILES AND THE CVT TRANSMISSION IS FAILING. NORMALLY YOU CHANGE YOUR TRANSMISSION FUEL EVERY 25,000 TO 50,000 MILES. MY MODEL MINI COOPER HATCHBACK DOES NOT COME WITH A RESERVOIR TO CHANGE SUCH A FUEL IT WAS A GUARANTEE BY THE MANUFACTURER THAT THESE MODELS WOULD NOT NEED SUCH A SERVICE AND THAT THE TRANSMISSION WOULD BE FINE THROUGHOUT THE LIFETIME OF THE CAR. WHAT WORRIES ME IS THAT I HAVE NOT BEEN ABLE TO DRIVE MY MINI OVER 50MPH DUE TO THE INCREASE OF RPM'S. WITHOUT THE SPEED INCREASE IT IS NOT SAFE FOR ME TO DRIVE ON THE HIGHWAYS AS I NORMALLY WOULD. A CVT TRANSMISSION REPLACEMENT COULD COST THOUSANDS. BUT MORE IMPORTANTLY I'M WORRIED ABOUT MY SAFETY ITS POSSIBLE THAT MY TRANSMISSION COULD FAIL WHILE MOBILE. THATS MY MAIN CONCERN. I RECENTLY READ THAT THERE HAS BEEN A LAWSUIT ADDRESSING THESE ISSUES. IT IS BMW'S DUE DILIGENCE TO ADDRESS THIS MATTER SEEING HOW THOUSANDS OF CITIZENS ARE OPERATING THIS MACHINERY ON A DAILY BASIS. *TR

I TOOK IT TO A SHOP AND THEY TOLD ME THE TRANSMISSION NEEDS TO BE REPLACED AND THE NUMBER THREE CYLINDER BLEW OUT AND I WOULD NEED TO REPLACE THE HEADGASKET AND REFURBISH THE ENGINE. WHEN I FIRST BOUGHT THE CAR IT WOULD PERIODICALLY KICK AND STALL OUT ON ME I TOOK IT BACK TO THE DEALER SHIP THEY TOLD ME IT WAS JUST THE ENGINE BREAKING IN.

I WAS YIELDING TO MAKE A LEFT TURN ON GREEN. THE CAR WAS IN NEUTRAL. IT WAS A RELATIVELY HOT DAY. WHEN I WENT TO GO I SHIFTED INTO GEAR AND IMMEDIATELY FOUND IT DIFFICULT TO TURN. AS I FURTHERED DOWN THE ROAD TO MY EVENT AND WAS USHERED INTO THE PARKING LOT BY TRAFFIC CONTROL, THE POWER STEERING DIMINISHED MORE AND MORE AS I DROVE ON. BY TIME I GOT TO A PARKING SPACE, I COULD JUST BARELY TURN INTO MY SPOT. A FEW HOURS AFTER THE EVENT I TURNED ON MY CAR AND IT DROVE AS NORMAL AGAIN. AFTER THIS POWERSTEERING FAILURE I HAD A POWER STEERING FLUID FLUSH DONE. IT HAS BEEN A BIT OVER A YEAR SINCE THE FIRST TIME IT HAPPENED, BUT IN THE PAST TWO WEEKS I'VE LOST MY POWER STEERING ABOUT TEN TIMES. IT'S ALWAYS WHEN I'M AT A SLOW SPEED OR STOPPED. USUALLY SHUTTING THE ENGINE ON AND OFF AGAIN WILL SOLVE THE PROBLEM BUT ONCE IT DID NOT. I LEFT THE CAR ALONE FOR A FEW HOURS AND WHEN I WENT TO DRIVE IT AGAIN IT WAS LIKE NORMAL. IT HAS NOT ALWAYS BEEN HOT WHEN MY POWER STEERING FAILS. I KEEP MY CAR IN A GARAGE SO IT IS SELDOM BAKING IN THE SUN. WHEN THE POWER STEERING GOES, IT FEELS AS IF THE CAR IS GRIPPING BACK AND GETS PROGRESSIVELY WORSE AS I CONTINUE TO DRIVE. I AM NOT AN AGGRESSIVE DRIVER AND I LIVE IN A FLAT AREA WHERE DRIVING IS A SIMPLE TASK. *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
