Common Problems with the
2025 MINI Cooper Mk5 (F66)

The family widened and updated in 2025: the Cooper Convertible (F67) launched from early 2025 with production returning to Oxford after nine years, MINI's February 2025 announcement layered on personalisation and usability changes for cars built from 1 March 2025, and reviewers kept flagging the missing manual - and the absence of paddle shifters unless options were added - as the driveaway gripe against the twin-pot Cooper S.

What changed for 2025

  • •Convertible (F67) joined the range with Oxford production resuming
  • •1 March 2025 build changes added colours, roof rails and extra content
  • •No manual gearbox across the range remains the defining buyer objection

Common MOT watch-outs

  • !Tyres and wheel condition on new-stock cars
  • !Infotainment and driver-assist update history
  • !Brake disc corrosion on low-mileage demonstrators
