Spontaneous engine fire of 2015 Mini Cooper S Countryman while parked and not used for 48 hours prior. The fire department guessed it was an electrical issue. It was put out with water and a fire extinguisher but the engine was severely damaged, melted plastic everywhere, electrical wiring burned completely and more. The engine appears unfixable, the front window was cracked by the heat and the hood with paint was burnt.
The vanos solenoid failed in the 2015 Mini Cooper, and immediately after the Alternator failed. My safety was put at risk in multiple ways: 1 - The engine was in a non-drivable state 2 - Significant smell gasoline was coming from the car 3 - Car had to be towed to a shop to determine what failed 4 - The shop fixed the vanos solenoid The problem was confirmed by the independent service center. When the vanos solenoid failed, the Check Engine and Oil lights came on. By the time the lights came on however, the vehicle was undrivable. When the alternator failed, the battery light came on. Repair of the vanos solenoid was $279.44 Towing to the shop was $155.00
IT'S NOT ABOUT SAFETY ISSUE BUT A DEFECT THAT COOLANT LEAK HAPPENED BETWEEN THE ENGINE BLOCK AND OIL FILTER HOUSING AT A CAR OF LOW MILEAGE RUN ( LESS THAN 30000 MILES, CLOSE TO 5 YRS). TO REPAIR THIS DEFECT, OWNER HAD TO PAY $1515 AT A MINI DEALER SERVICE.
2015 MINI COOPER COUNTRYMAN PURCHASED NEW FROM FACTORY. HAVE HAD REGULAR ROUTINE MAINTENANCE SINCE PURCHASE. AROUND 48,000 MILES STARTED HEARING RATTLE NOISE FROM FRONT DRIVERS SIDE OF ENGINE COMPARTMENT. DEALER COULDN'T FIND ANYTHING. NOISE ONLY NOTICEABLE AT LOW SPEEDS AND WHEN CLUTCH UNDER LOAD. GOT WORSE OVER TIME, SO TOOK IT TO DEALER AND WORKED WITH MECHANIC TO IDENTIFY ENGINE. THEY CHECKED MOTOR MOUNTS WHICH APPEARED FINE, BUT WHEN THEY REMOVED THEM, MOUNTS WERE FOUND TO BE FAILED. BOTH MOTOR MOUNTS HAD TO BE REPLACED. THIS IS QUITE UNACCEPTABLE CONSIDERING I HAVE KEPT THE CAR IN THE GARAGE, I DON'T DRIVE IT LIKE I STOLE IT, AND I KEEP UP ON ALL THE REQUIRED MAINTENANCE.
