What owners report

  • Power steering suddenly fails at low speed, causing loss of control and collisions.
  • Power steering pump or module overheats and catches fire, sometimes while the car is parked and off.
  • Electrical fires start under the hood with a burning smell, tied to alternator and power steering wiring.

  • Convertible top opens unevenly on one side due to a cable issue, requiring full unit replacement.

    Air bags:frontal

    BMW of North America, LLC (BMW) is recalling certain model year 2005-2006 MINI Cooper and Cooper S vehicles manufactured January 5, 2005, to November 28, 2006, and 2005-2008 MINI Cooper Convertible and Cooper S Convertible vehicles manufactured January 5, 2005, to July 31, 2008. Due to manufacturing, installation, and exposure issues, the front passenger seat occupant detection mat may not function properly and, as a result, the front passenger air bag may not deploy in a crash.

    Risk: An improperly functioning mat may cause the passenger frontal air bag to be inactive when the seat is occupied, and in the event of a crash, the air bag will not deploy, increasing the passenger's risk of injury.

    Remedy: MINI will notify owners, and dealers will replace the front passenger seat occupant detection mat, free of charge. The recall began on October 12, 2015. Owners may contact MINI customer service at 1-866-825-1525.
