Issue: passenger seat belt light continues to remain on after the passenger is no longer sitting on the seat. root cause from dealer: defective passenger occupancy sensor. only way to turn off the seat belt light is to either put the passenger seat belt on or turn on and off the car. i noticed when i purchased the infiniti 2011 m56 the seat belt light would remain on after a passenger has been sitting on the passenger front seat and exits the vehicle. the passenger just needs to sit on the passenger side for a few minutes to exhibit this problem. this is a safety concern as i don't know if the airbag will deploy properly as the occupancy sensor is falsely triggering a passenger is sitting in the passenger side. the airbag light indicator will sometimes be on or off when the seat belt light comes on. after taking the car back and forth on multiple occasions and to multiple infiniti dealerships, was finally able to to get to the problem. one of the dealership was finally able to conclude it was due to the front passenger occupancy sensor. even had an infiniti engineer from the norther ca region confirm the issue was indeed due to the occupancy sensor. this issue was first reported when under the original warranty however infiniti and infiniti consumer affairs will not honor the original warranty. also i have the extended warranty just for this purpose however this part is not covered.
