Two problems related to warning light on have been reported for the 2010 Mini Cooper S. The most recently reported issues are listed below.
The passenger airbag sensor/passenger seatbelt sensor issue that has been reported and fixed in lots of other Mini cooper model years is seemingly an issue with 2010 models too and needs to be corrected via recall. The sensor being faulty is a serious safety concern, and runs close to $1200 to repair. My sensor was intermittently off and on and is now full time warning about the airbag being off. This happens no matter the status of the vehicle - as soon as the motor is running the warning lights are lit up.
Airbag and seatbelt warning lights come on for passenger seat and will not turn off. It indicates that the passenger airbag will not activate in the event of an accident with an occupant in the passenger seat. Front passenger will not have airbag protection in the event of a crash.
