   The rear windshield fell out of the top of my convertible. There was no accident or foul play involved. The glue that bonds the window to the top became unglued. This happened at 70,000 miles. The top is made of fabric and the window is made out of glass. Have to you replace the entire top to repair it. Not sure why this is not a recall. It is a well-known problem for the car.

   The fuel filling nozzle turns off repeatedly (as if already full) while filling the fuel tank. About 1/4 to 1/3 of a gallon of fuel will go in before it turns off, backs up, and the gas overflows onto the outside of the car and onto the concrete. It happens regardless of the pump being used. It started happening occasionally a few months ago if the tank was refilled when a quarter full. It now happens consistently, no matter the fuel level. I had the car put on a lift and the system diagnosed today. The mechanic said the cause is a faulty service valve within the fuel tank assembly. They also said it is a known issue with F56 Mini Coopers.

   The back window comes unglued to the convertible top when the car is parked outside in warm weather. Ive seen this in several other mini cooper roadsters within the past few weeks. This causes the car to have a hole in the convertible top and leaves the glass hanging from the sensor. To fix it you need to buy a whole new top. This HAS to be a design defect.

   While driving in the rain (light rain) front right and rear left brakes locked up. No warning lights came on, it was a very dangerous situation. The car is currently at a repair shop getting looked at, I had to have it towed there because those wheels will not turn while in neutral even. Reading forums this is a common problem, very serious and dangerous especially with no warning.

    FUEL FILLING NOZZLE SHUTS OFF REPEATEDLY WHILE REFUELING. UPON GASSING UP, VALVE CLICKS IMMEDIATELY AND PUMP SHUTS OFF LIKE IT'S FULL NO MATTER WHICH GAS STATION OR PRESSURE I EXERT. I SAW A BULLETIN "SI M16 01 15" WHICH AFFECTED MINIS PRODUCED IN 2014 BUT DID NOT INCLUDE MY 2015 COOPER S. A COMMENT FROM THE BULLETIN HAD A TEMPORARY SOLUTION WHICH IS TO ANGLE THE PUMP TO 45, THEN PUMP SLOWLY AT THE MAGIC SPEED, THOUGH THIS CAN TAKE ANYWHERE FROM 10 TO 30 MINUTES. THIS IS DANGEROUS ON MY PART AS I TRAVEL PAST MIDNIGHT FOR SEVERAL HOURS AND SPENDING MORE TIME AT A GAS STATION IN THE DARK IS WORRISOME. I DO GET SPILLS OCCASIONALLY WHICH I HAVE TO KEEP WIPING AND IS A STATION HAZARD. REPLACING THE FUEL TANK COMPLETELY AT AN ESTIMATED $2K+ IS TOO COSTLY ESPECIALLY DURING THIS PANDEMIC AND IS DUE TO FAULTY MANUFACTURING.
