Front Air Bag Sensor Control problems of the 2013 Nissan Leaf

In 2017 I brought in my Nissan Leaf to be serviced for a recall notice for the OCS sensor. Before then, the OCS sensor seemed to be working fine but I figured I should perform the service for safety. This last year the OCS sensor has stopped working completely. Now I have a red blinking light that warns that the passenger air bag is not working. I took it to a Nissan service center, they want to charge me $1000 to replace the OCS control unit and sensor. I feel like these were parts that were changed as part of the recall and are obviously defective since they crapped out after a few years.

Passenger airbag shows off when passenger in the seat is a typical adult, ~130 pounds. The underseat sensor (ods occupant detection system) is not calibrated - needs about 160 pounds to sense a person in the seat. Nissan had a recall (March 2013) for this exact problem. They claim that this vehicle was not included. It is a safety issue. Nissan hotline (alex allen) says take it to the dealer. The dealer says call Nissan. This car needs to be a part of the recall.
