One problem related to air bag has been reported for the 2009 Mini Cooper S Clubman. The most recently reported issues are listed below.
Multiple times, however, never when the dealer looks at it, my "airbag off" light comes on while a person of adequate weight is sitting properly in the seat. Once it comes on it does not come off until the seat is empty or the car is turned off. Dealer won't do anything if there isn't a fault code and can not duplicate error. It's in for the fourth time for this problem. Seems to be a major safety issue.
