What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2015 MINI Cooper S, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
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 contact owns a 2015 Mini Cooper S. The contact stated that the vehicle previously had the fuel carbon filter replaced; however, the failure recurred while attempting to refuel the vehicle. The fuel tank dispersed the gasoline outward, spilling on the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the fuel tank needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact to file a complaint with the NHTSA. The failure mileage was approximately 67,000.

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.

The vehicle was taken to the dealer where it was diagnosed that the seat mat needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that the request for assistance was denied. The failure mileage was approximately 80,000.

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
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 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.

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
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.
THE HORN CONTACTS ARE CORRODED AND THE HORN WILL NOT WORK CONSISTENTLY. IT MAY TAKE 5 OR 6 TIMES PUSHING THE HORN TO GET IT TO ACTIVATE, OR HOLD IT DOWN FOR A LONG TIME AND TRY TO MOVE IT AROUND TO SCRAPE THE CORROSION OFF THE CONTACTS TO GET ACTIVATION. IT OCCURS WHETHER DRIVING OR STATIONARY. MANY OTHER OWNERS HAVE REPORTED THIS PROBLEM ON A MINI COOPER FORUM. MY VEHICLE ONLY HAS 20,000 MILES ON IT.

From owner reports, verbatim
THE CARS TRANSMISSION JUMPS OUT OF 1ST GEAR WHEN TURNING ONTO A CITY STREET OR ACCELERATING FROM A STOPLIGHT ON A CITY STREET. I WAS ALMOST REAR ENDED 3 TIMES THIS WEEK AND IT'S VERY DANGEROUS. THIS HAS HAPPENED NUMEROUS TIMES THIS PAST WEEK AND IS A DOCUMENTED PROBLEM WITH THE 2015 MINI COOPER S MANUAL. MY CAR ONLY HAS 25,400 MILES ON IT. THE WARRANTY JUST EXPIRED ON 05/18/2019 (OUT BY DATE) THIS MONTH AND THE DEALER REFUSES TO REPAIR THE PROBLEM UNDER WARRANTY. IF THIS IS A DOCUMENTED PROBLEM, WHY DOESN'T THE DEALER TAKE THE STEPS TO FIX IT PROPERLY?
