Audi A3 Equipment problems by year

would have to instruct my passenger to disengage the seatbelt and re-engage it in order for the airbag to come back on and recognize that there is a person over the minimal weight requirement occupying the seat. This issue have continued to occur on and off throughout the year. On nov. 6Th, I was in an accident(rear-ended) with no major injuries. That accident was luckily not very severe and I am very fortunate that I didn't hit the car that was in front of me and needed my airbag to deploy and I wouldn't due to a faulty airbag sensor that was fine until the recall campaign in 2019. So on friday, nov 13th, I took my car in for diagnostic testing at the dealership and when the service department called, I was told that it was in fact my sensor inside my front passenger seat that is malfunctioning. This did not occur until the wiring and connector was changed in dec 2019. I have contacted the corporate office of the auto maker and they are refusing to pay any part of the cost to have the sensor replaced and I am being quoted a repair price of $1200 and that's just for the part alone. This is a safety issue and I feel that since the company issued a recall campaign for the replacement of the wiring and connector, they should do the same for the airbag sensor before a fatal accident occurs to a passenger of the same type of vehicle with the same issue. There are currently several complaints about the exact same issue posted on this site and several others.
