What owners report

  • Passenger seat occupant sensor wiring is too short and gets damaged when the seat slides back, causing the airbag system to falsely detect an empty seat and disable the passenger airbag.
  • Power steering fails intermittently while driving, sometimes with a loud noise and a leak from the power steering pump, at a median mileage of 81,800 miles for steering complaints.
  • Passenger airbag warning light stays on continuously even when the seat is occupied, raising owner concern about whether the airbag will deploy in a crash.
  • A loud clunk from the drivetrain preceded reported transmission trouble at 81,000 miles.
  • The motor mount was reported to leak hydraulic fluid at low mileage, with one owner noting failure at 18,350 miles.

    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.
