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.
Lower Engine Support and Passenger Engine Mount damaged as per routine inspection by dealer in Feb2025. Never diagnosed before. Repair done by independent service center in Feb2025 and I have receipt of approximately 1K. Also, since 22feb2025, I am not able to add fuel to the tank because the pump stops constantly and causes spill of fuel. This can cause fire. Never happened before. Tried at least 4 different gas station and same result. Dealer charges over $200 to perform inspection/diagnostics. Not done yet. Repairs to fuel tank are in the thousands. No warning in the car dashboard for none of the issues. Car with less than 80k miles.
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.
Defect in passenger frontal airbag-The front passenger seat occupancy detection mat is not functioning correctly. This was recalled but not for my VIN and needs to be part of the recall.
While driving the rear view mirror suddenly tilted downward (drooped). What happened, was that the tension ring popped off. As it turns out, this is a known issue per internet Mini Cooper pages. On hot days the ring loosens and, since the design does not include anything to prevent the ring from sliding off, it does slide off, resulting in the rear view mirror drooping. I reinstalled the ring. This occurred again the next day. I ended up uninstalling the rear view mirror, reinstalling the ring and gluing it in place. Thus far this has held.

The sensors do not work. The car does not tell me when oil is needed, when my tires are low. No sensors work in the car. The dealer, Mini Of Edison, states FOUND INTERNAL HARDWARE FAULTS. But are stating its costs 2300.00 to fix. This is a huge safety issue.Ive been having to guess when my oil is low and when my tires are low. This has been going on since September 2023, the car was only bought in May 2023.
The fuel filling nozzle turns off repeatedly while trying to fill the fuel tank and spills out causing a safety and environmental hazard, regardless of the pump being used. As a result, no fuel goes into the gas tank, instead it goes all over the car and the ground.
