Passenger seat airbag on/off switch sensor needs replacement according to Nissan dealer. Passenger airbag "off" light is flashing even with 125 pound passenger in seat. Nissan couldn't tell me whether or not passenger airbag was really on or off. Quoted $2400 to replace the passenger seat airbag switch and seat assembly because is no longer under warranty according to Nissan. This appears to be exactly the problem covered by 2013 Leaf recall for hardware manufacturing problem in same sensor.
