2011 Nissan Leaf air bags problems

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.

While driving the vehicle straight at around 35 MPH, the airbag light came on. Subsequent diagnosis showed a b1018 code thrown by the leaf, which indicates that the passenger occupancy sensor has failed. The code was reset and stayed off, but again about 5 days later, the same issue occurred. This time, the code would not reset. I was quoted $2700 in parts and $300 labor by the dealership to repair the problem, which was uneconomical and more than half the value of the car.
