Known problems on the Mini Cooper / Cooper S 5-door (F55)
Seat side airbag recall
Costly if missed
2017 · petrol · Paperwork
What to look for: Ask for proof the seat side airbags were replaced under the recall, and check the airbag light goes out after start-up.
Why it matters: NHTSA 16V-914 records side airbag inflator initiators that may fail to ignite in a crash; remedy is module replacement.
What to look for: Ask for proof the driver's seatbelt was replaced under the recall, as tugging the belt will not show this fault.
Why it matters: NHTSA 16V-747 records that the vehicle-sensitive locking mechanism of the driver's Emergency Locking Retractor may not lock as designed (FMVSS 209 non-compliance), so in heavy braking the retractor may lock with the occupant further forward in the seat; the remedy was a new driver's seat belt assembly.
