After the passenger would vacate the car the passenger seat belt alarm would come on and stay on till I would take action by hitting the seat with my palm. I tried three times in having the dealership to repair the seat pad sensor while it was under warranty, but they said they could not duplicate it. After the warrant expired I returned it the dealership and then they said it was a defective seat pad sensor. (ugh)

Passenger seat - seat/airbag occupancy sensor failed. The airbag and seatbelt light remains lit. BMW said not covered under any warranty even though it's a safety issue. Estimated cost to repair - $3,000. Apparently airbag and seatbelt will not engage if sensor is not working

- Neptune, NJ, USA

Spurious "passenger not wearing seatbelt" alert when there is no passenger. Diagnosed as "passenger seat mat sensor faulty" with a replacement cost of $2,498.87. Should be covered by a recall as this is a safety issue. Apparently similar issue led to a recall in older BMW vehicles.
