general problems of the 2010 Volvo S80

The air bag warning randomly popped up on my screen. They will not deploy if I get into a wreck. Non working air bag. I also have issues that come and go with the electrical component. Sometimes my door won't open, sometimes my seats won't move, and my license plate light is out due to something electrical. My gas tank spits gas back at me and makes weird noises sometimes.

"srs (supplemental restraint system) airbag failure urgent" message came on. I took vehicle to the dealership for repair. The diagnosis was a faulty (r) front passenger seat belt assembly, which was replaced. Several days later the fault message returned. Dealership checked codes and indicated it was the same exact part. I had the previous owner's service history for the car and discovered this problem had occurred 6 months prior to me purchasing the vehicle and another dealership had already replaced the same seatbelt assembly. So instead, the current dealership replaced the control module for the entire srs system. Two days later the fault message returned again. The car is back at the dealership for the third time now and has been there for a total of about a month. They are not sure exactly what the problem is, but suspect the wiring harness under the front passenger floor area. I have researched this issue quite a bit and have discovered a recall involving the connection for the clock spring in the steering wheel for my 2010, but more telling is a recall affecting 17,000 vehicles encompassing many models my 2012 for a wiring problem where the seat harness may become disconnected when moving the seat. Perhaps even though my vehicle is a 2010 it still could be the same problem since not much has changed between these model years. I have also learned that the srs system disables the airbags when this fault occurs so this represents a major safety rist to me and my family.
