Seat Belt problem #1

* the passenger airbag light came on July 2025. I was not in a accident the light just came on. * 7/29/2025 I took my car in for service at infinity of las vegas (the only infinity dealership in las vegas) I asked to check why the airbag light was on. I was told the occupant sensor unit was abnormal. Sensor and module internally shorted out. Recommend to replace passenger front seat frame assembly (only available as a 1 piece both sensor and module internally shorted seat frame assy). @ $ 8678. 76. Because it’s a different seat from the original seat, I would have to also replace the seat belt. @ 116. 87. * it is not recommended to drive a car with the air bag light on. This car is my only source of transportation. * on August 4, 2025 I took my car to auto dynamic services and they suggested initial repair was to replace the occupant detection module. The part was ordered from Nissan, when they received the part it was an updated part design which was slightly larger with more pins than the original part and could not be used on my car. They reordered the part from another Nissan retailer ensuring it matched the original part for my car. Now it’s Aug. 27th, 2025. Auto dynamic received the correct replacement module. Unfortunately the part was replaced and the airbag light came on again. They also stated the seat would have to be replaced in order for the airbag light to go off. For around the same price. It cost me 1800. 00 to find this out. * I do not have money to resolve this issue especially if the driver airbag errors next, I am fearful of the unknown driving around with the airbag light on. If in an accident possibly not being covered because I was driving with a know issue. Or the bags just deploying randomly. * on [xxx] I traded a perfect running car in, I did not receive much on the trade as the airbag light is on. I can drive safely and register the car when required * it looks like there was a recall but the Q50 2. 0 turbo was not included. Information redacted pursuant to the freedom of inf.
