Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 2 tested variants for this model year.
Complaints for the 2015 MINI Cooper S are spread across a small number of reports, with the most recognizable pattern involving the convertible top. Multiple owners describe the rear glass separating from the fabric top, the adhesive bond fails, leaving a gap and the glass hanging in place, and the fix requires replacing the entire top rather than just regluing the window. Engine-related complaints include a recurring fueling issue where the pump nozzle repeatedly shuts off prematurely, causing fuel to back up and overflow before the tank is full. A couple of owners raise airbag concerns, specifically that the passenger seat occupancy sensor may not correctly detect a seated occupant. One report describes brake lockup on wet roads with no warning lights, though that appears to be an isolated account.

By System
The 2015 MINI Cooper S has 5 recalls, the most serious being a transmission software issue that can allow the driver to exit the vehicle while it is not in Park, leaving it free to roll away.
Several recalls involve airbag and occupant safety systems. The passenger seat sensor that determines whether the front passenger is an adult or child can misread the occupant, causing the airbag to activate or deactivate incorrectly in a crash. The front passenger airbag may also fail to deploy in a low-speed collision, reducing protection for that occupant. On the structural side, a defect in the front seat's backrest adjustment mechanism can allow the seatback to shift out of position in a severe impact, and certain two-door models do not meet side impact protection requirements for rear seat passengers, raising the risk of injury in a side collision.
