What owners report

  • Electro-hydraulic power steering wiring overheats and smokes, sometimes while the car is parked and off.
  • Power steering suddenly turns hard to move, then loosens and can cause oversteer or pump failure.
  • Steering warning lights come on along with loss of power assist, prompting owners to stop driving immediately.
  • Engine bay fires start while the car is parked in a garage or driveway, with white or black smoke reported.
  • Front passenger airbag deploys in a crash even when the seat is unoccupied, in one case causing a burn injury.
  • Heated seats short out and burn holes through the seat cushion and clothing.

2005 MINI Cooper S recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 15V660000Oct 15, 2015Steering86,018 vehicles

    Steering:electric power assist system

    BMW of North America, LLC (BMW) is recalling certain model year 2002-2005 MINI Cooper and Cooper S vehicles and 2005 Cooper and Cooper S Convertible vehicles. The affected vehicles may experience temporary or permanent loss of the electro-hydraulic steering assistance.

    Risk: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, potentially increasing the risk of a vehicle crash.

    Remedy: MINI will notify owners, and dealers will inspect the electro-hydraulic power steering system, replacing the components and wiring, as necessary, free of charge. Interim notices were mailed to owners on December 10, 2015. Owners will receive a second notice when remedy parts become available. Owners may contact MINI customer service at 1-866-825-1525.

  2. NHTSA 15V205000Apr 6, 2015Airbags91,800 vehicles

    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.
