2005 MINI Cooper power train problems

“The transmission will cycle first through third and when it tries to go into 4th it slips and will not operate higher gears it caused me to lose my forward drive momentum as I was switching lanes and the car I was getting in front of almost ran into me.”

“WHEN DRIVING VEHICLE TRANSMISSION SLIPS CAUSING A JERK REACTION IN THE VEHICLE AND THEN IT WILL RENEGADE CAUSING ANOTHER JERK REACTION IN THE VEHICLE AND MAKES GOING AND OR STOPPING UNPREDICTABLE. TURNING LEFT IS DANGEROUS AS THE CAR MAY NOT MOVE FORWARD AT A SPEED THAT IT SHOULD OR MAY JERK IN THE MIDDLE CAUSING THE VEHICLE TO STOP IN FRONT OF ONCOMING TRAFFIC. I HAVE HAD A MACHANIC CHANGE THE TRANSMISSION AND IT STILL DOES THE SAME THING. I HAVE CONTACTED THE MANUFACTURERS WHO INFORMED ME THAT THERE WERE NO RECALLS AND NOTHING THEY WOULD DO.”

“THE POWER STEERING ASSIST HAS ALL BUT STOPPED WORKING, WITH STEERING NOW DIFFICULT AT LOWER SPEED--ESPECIALLY WHEN I FIRST START THE ENGINE IN THE MORNING. THE CLUTCH DOESN'T RESPOND WELL AND THE VEHICLE NO LONGER GOES INTO SECOND GEAR. THE REAR LEFT BRAKE CALIPER SEIZED IN PLACE, NOT ALLOWING THE BRAKE PAD TO RETRACT COMPLETELY AND THEREFORE THE BRAKE PAD CONTINUOUSLY RUBBED AGAINST THE DISC, BUT WITHOUT NOISE. NOT UNTIL THE LEFT REAR BRAKE MADE NOISE BECAUSE OF THE METAL ON METAL BRAKING WAS THE SEIZED OEM CALIPER IDENTIFIED, WHEN I PUT ON A SET OF NEW BRAKE PADS. NONE OF THE OTHER THREE BRAKES HAD THE SEIZED OEM CALIPER.”

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

“FRONT DRIVER SEAT OCCUPANT DETECTION MAT DOESN'T SEEM TO BE WORKING CORRECTLY AS IT DOESN'T DETECT SOMETIMES WHEN THERE IS AN OCCUPANT. SECOND ISSUE IS THE CVT TRANSMISSION OF THIS VEHICLE. I GET A JERKING MOTION EVERY NOW AND THEN AND FOUND A CLASS ACTION LAWSUIT LINKED WITH THESE TRANSMISSIONS. I PURCHASED THIS CAR AFTER THIS LAWSUIT BUT APPARENTLY THIS PARTICULAR VEHICLE WAS NOT TAKEN CARE OF. MY VEHICLE ONLY HAS 70,000 MILES ON IT AND FIND THIS UNACCEPTABLE.”

“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…”
