What 119 owners told NHTSA about the 2012 Mini Cooper Countryman

The contact owns a 2012 Mini Cooper Countryman. The contact stated that while driving at undisclosed speeds, the vehicle stalled. The fuel tank was a third of the way full. The trunk was locking and unlocking continuously while driving or while the vehicle was parked. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 23V337000 (Electrical system). The contact called the local dealer, but the vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who determined that there was a short in the footwell module due to water intrusion. The drain was also clogged in the sunroof. The manufacturer was contacted and opened a case. The failure mileage was approximately 161,818.

When the vehicle computer detects low voltage all turn signals, lights and instrument cluster immediately fail and do not turn back on. The Foot Well Module (FWM) or Foot Rest Module (FRM) computer becomes corrupt and deletes data from the module. This becomes a major safety hazard as a nighttime failure occurred causing several near accidents due to inability to signal to other vehicles. This is a known issue with Mini and they released an extended service bulletin knowing the factory footrest modules were manufactured incorrectly. Vehicles falling outside the initial warranty period are prone to safety risks when this occurs.

This car was maintained, by Mini and BMW authorized mechanics and only had OEM parts installed and followed management of vehicle as directed by manufacturer, throughout its history. It was always driven and kept in moderate weather conditions, no extreme heat, cold, wet, or speeds. Used almost daily for 30-60 minute commutes. Just after 100K miles, total engine failure was suddenly experienced on the freeway, due to combustion in two valves, damaging two cylinders and sudden leaking of the exhaust system under the hood. The manufacturer, BWM, has been shown evidence of malfunctioning of the four cylinder engine and will not show evidence of their grounds for why they will not take responsibility.

MY MOTHER WHO OWNS THIS 2012 MINI COOPER HAS SUDDENLY NOW STARTED HAVING ISSUES WITH HER WATER PUMP LEAKING. I TOOK IT TO THE DEALERSHIP AND WAS TREATED WITH THIS RUDE EMPLOYEE BY CHRISTOPHER GUZMAN WHOM HAD A VERY UNPROFESSIONAL AND NO EMPATHY. VERY SHORT WITH RESPONSES AND SARCASM.KEEP IN MIND MY MOTHER IS ELDERLY AND KNOWS NOTHING ABOUT CARS. SO I LOG INTO TO YOUR SITE AND SEE THERE IS A RECALL ON WATER PUMPS BUT MY MOTHER'S IS NOT ONE OF THEM. AND GUESS WHAT HER WARRANTY JUST EXPIRED MARCH 2019. GO FIGURE. SO IF SOMETHING WOULD HAVE HAPPENED TO MY MOTHER BECAUSE OF DEFECTIVE WATER PUMP. AND HOW FUNNY HOW MY MOMS CAR WAS NOT A RECALL. I WOULD QUALIFY FOR THAT ACTION LAWSUIT. HOW DOES A 2012 WATER PUMP JUST GIVE UP WITH VERY LOW MILEAGE 24 000 I WOULD LIKE TO ESCALATE THIS FURTHER AND AN EXPLANATION HOW THIS COULD HAVE HAPPENED!! LOOK AT THE MILAGE!

THE WATER PUMP IN THE CAR FAILED WITHOUT WARNING OR CHECK ENGINE LIGHT COMING ON, CAUSING IMMEDIATE OVERHEATING AND THE HEAD GASKET ON THE ENGINE TO BLOW. MINI REFUSED TO FIX THE CAR, AS THEY SAID IT WAS OUT OF WARRANTY, DESPITE THE FAULTY WATER PUMP BEING THE CAUSE OF THE OVERHEATING.

THE CORE PLUG FAILED ALLOWING COOLANT INTO THE CRANK CASE. THE MINI AUTOMOTIVE REPAIR FACILITY SPECULATED THAT THE VEHILCE MUST HAVE BECOME OVERHEATED TO THE POINT OF DAMAGING THE CYLINDER HEAD. AT FIRST IS WAS THOUGHT THAT A REPLACEMENT CYLINDER HEAD WOULD COST $9K. UPON FURTHER INSPECTION, IT WAS DETERMINED THAT THE CRANK CASE WAS TO BADLY COMPROMISED FOR ADEQUATE REPAIR AND THE ENTIRE ENGINE NEEDED TO BE REPLACED AT A COST THAT EXCEEDED THE MARKET VALUE OF THE VEHICLE. SINCE IT WAS NOT ECONOMICALLY FEASIBLE TO REPAIR THE VEHICLE, I WAS FORCE TO PURCHASE AN ALTERNATE MODE OF TRANSPORTATION. BEING THAT THE VEHICLE COULD NO LONGER BE DRIVEN WITH OUT A COSTLY REPAIR, I CHOSE TO DONATE IT FOR CHARITY. MY COMPLAINT IS THAT IF THE VEHICLE OVERHEATED, I WAS NOT AWARE OF IT AS THE DRIVER INFORMATION GAVE NO ALERT. THIS VEHICLE WAS NOT EQUIPED WITH A TEMPERATURE WHICH MAY WHICH SHOULD HAVE INDICATED THE ENGINE TEMPERATURE WAS OUTSIDE OF NORMAL OPERATING PARAMETERS. HOWEVER, THE CHECK ENGINE LIGHT CAME ON WHICH I PROMPTLY TOOK TO HAVE IT SERVICED. THE CODE WHICH INITIALLY PRESENTED AND PROMPTED ME TO VISIT THE DEALERSHIP REPAIR FACILITY TO BEGIN WITH. THE VEHICLE GAVE NO TEMPERATURE WARNINGS THROUGH THE DRIVER INFORMATION DISPLAY AND THE THE PERFORMANCE OF THE VEHICLE DID NOT CHANGE; I DROVE THE VEHICLE TO THE DEALERSHIP THE NEXT DAY WITH NO PROBLEM. MY CONCERN IS, THERE ARE NUMEROUS ACCOUNTS THAT CAN BE FOUND ONLINE OF DRIVERS THAT GAVE AN ACCOUNT SIMIULAR TO MY EXPERIENCE - FAILURRE OF THE CORE PLUG WITH NO NOTIFICATION THROUGH THE INSTRUMENT PANEL. AND, IN MANY CASES, THEY WERE ALSO TOLD BY THE MAKER'S REPAIR SHOP THAT THE ENGINE OVERHEATED BUT COULD NOT EXPLAIN WHY THE DRIVER WAS NOT ALERTED. WHILE I DID NOT PAY FOR ACTUAL REPAIRS, I WOULD NOT HAVE NEEDED TO BUY REPLACEMENT VEHICLE. I ALSO HAD THE VEHICLE SERVICED IN ACCORDANCE WITH THE MAINTENCE SCHEDULE.

DRIVING ON HWY AND MY CAR WOULDN'T ACCELERATE NO WARNING LIGHTS WENT OFF ON THE CAR SO I PULLED TO THE SIDE OF THE ROAD AND HAD IT TOWED TO A SHOP THAT SAID THAT THERE WAS SOME SORT OF COOLANT LEAKAGE AND A MALFUNCTION OF THERMOSTAT SO THE ENGINE OVER HEATED. THEY WANTED TO CHARGE ME 10,000 TO FIX IT AND THE WARRANTY THAT I BOUGHT FOR 2999.00 DID NOT WANT TO COVER THE COST. SO THE SHOP CHARGED ME 1500.00 TO TAKE THE HEAD APART AND I HAD TO TOW IT BACK HOME WHERE IT SITS IN MY DRIVE WAY.

VEHICLE WAS IN MOTION ON A HIGHWAY AND, AFTER GOING OVER SEVERAL POT HOLES, THE ENGINE TEMPERATURE WARNING LIGHT CAME ON. THE ENGINE POWER WAS REDUCED, AND THE ENGINE FAILURE LIGHT ALSO APPEARED. THIS IS WHEN I PULLED OVER INTO THE OFF RAMP, AND THE VEHICLE CAME TO A SPUTTERING STOP. I PLACED THE CAR IN NEUTRAL AND PUSHED IT TO THE DIRT SIDE LANE OF THE OFF RAMP. I OPENED THE HOOD, SMELLED SOMETHING BURNING, AND SAW SMOKE COMING FROM THE ENGINE. I COULD SEE BURNT CIRCUITS, BURNT PLASTIC, AND COOLANT LEAKING ALL OVER THE ENGINE AND EXPOSED WIRING. HAD IT NOT BEEN FOR IMMEDIATELY EXITING ONTO THE OFF RAMP, THE VEHICLE WOULD HAVE STOPPED IN THE MIDDLE OF THE HIGHWAY WITHOUT WARNING. I COULD HAVE ALMOST DIED BECAUSE OF THE FIRE; THIS FAULTY ENGINEERING BY BMW/MINI HAS ALREADY TAKEN THE LIFE OF A DRIVER IN SOUTH KOREA. BMW ISSUED A RECALL OF THE 2012 MINI COOPER S ROADSTER, BUT WHEN I HAD THE CAR TOWED TO ONE OF THEIR SERVICE CENTERS, THE TECHNICIANS WERE UNAWARE OF THIS MANUFACTURING DEFECT AND STATED THAT THE REPAIR PARTS ARE UNAVAILABLE. I SEE THAT MY VEHICLE HAS BEEN RECALLED, BUT WHEN I TYPE IN MY VIN, NO RECALL IS ATTACHED TO MY VEHICLE. BMW/MINI IS TAKING NO ACTION; THEY ARE HARMING AND KILLING DRIVERS OF ITS VEHICLES.

I'M JUST NOTICING A COOLANT LEAK PUDDLING UP UNDER FROM WHAT I WAS TOLD WAS THE THERMOSTAT OR IT'S HOUSING OR BOTH.. MY ENGINE SOUNDS LIKE IT'S RUNNING WITH NO OIL. I GO TO CHECK THE DIPSTICK AND THE OIL AT THE VERY END OF IT SEEMS ALMOST IMPOSSIBLE TO ACCURATELY READ, BECAUSE IT'S NOT UNIFORM IN IT'S COATING AT THE TIP OF IT. LIKE IF IT WAS SPLASHED ON. NOT SURE IF THE AUXILIARY COOLING SYSTEM IS EVEN WORKING ANYMORE, WHICH USED TO RUN FOR A MINUTE OR TWO AFTER ENGINE SHUT DOWN. I'M ADDING THE OEM SPECIFIED COOLANT ALONG WITH WATER, 50/50, EVERY DAY NOW, BECAUSE THE RESERVOIR SHOWS IT'S LOSS OF COOLANT. VIN CHECK SHOWS NO RECALLS, BUT I'M HAVING THE SAME ISSUES AS THE RECALLS. I JUST WANT MY VEHICLE RUNNING LIKE IT WAS WHEN I FIRST GOT. I BEGAN FINANCE ON THE VEHICLE LESS THAN A YEAR AGO, AND I STILL OWE 16K ON IT. I SHOULDN'T BE WORRIED ABOUT THE CAR DYING OUT ON ME ALREADY. BAD ENOUGH I WORK 35 MINUTES AWAY AND PUBLIC TRANSPORTATION INCLUDING HELP FROM ANYONE IS ALSO PRETTY MUCH IMPOSSIBLE. IT'S STRESSING ME OUT BIG TIME. I CAN'T AFFORD TO GET FIRED. WHERE I WORK, THEY DON'T CARE ABOUT MY ISSUES. I ALSO REQUIRE AN IID EQUIPPED VEHICLE, SO RENTALS ARE OUT OF THE QUESTION, OTHERWISE, I PROBABLY WOULDN'T BE HERE WRITING THIS MESSAGE! THANK YOU. I REALLY FEEL UNSAFE BEING ON THE HIGHWAY AS WHO KNOWS IF MY CAR'S ENGINE EVEN HAS OIL. OR IF THE COOLANT HOSES WILL JUST BLOW OFF. EITHER WAY, I FEEL LIKE I'M RIDING WITH DEFECTIVE EQUIPMENT. I TRIED TO BABY THIS CAR DRIVING, BECAUSE I CAN'T AFFORD A 16K BROKEN CAR. I FEEL TRAPPED.

TEMPERATURE SENSOR IN RADIATOR HOSE LEAKING. NEEDS UPPER RADIATOR HOSE, AND THERMOSTAT WITH HARNESS TO CORRECT. DISCOVERED DURING A ROUTINE OIL BRAKES ETC INSPECTION BY THE DEALERSHIP. I WAS TOLD THERE WAS A CHANGE IN THE HARNESS AND THE NEW ONE HAS A "COMPUTER" AND WOULD COST $1450 TO FIX. THIS IS AN UPPER HOSE AND I LOOKED ONLINE AND FOUND THE REPLACEMENT HARNESS HAS TOW SEPARATE CONNECTORS, ONE FOR COOLANT TEMP SENSOR AND THE OTHER FOR THE COOLANT THERMOSTAT. I HD CHECKED MY FLUIDS TWO DAYS BEFORE ON A COLD ENGINE AND THEY WERE FINE AND WATER OVERFLOW WAS AT THE PROPER LEVEL. I CHECKED MY COOLANT OVERFLOW TANK THE DAY AFTER VISITING THE DEALERSHIP ON A COLD ENGINE AND THE OVERFLOW TANK WAS LOW... I ADDED WATER... IT HAS NOT GONE DOWN FOR SEVERAL DAYS. I HAVE HEARD THERE IS CORROSION THAT HAPPENS AND THE THERMOSTAT MAY NOT EMPLOY AND YOU CAN HAVE AN OVERHEATED ENGINE.
