2013 Lincoln Mkx

I bought the car 1 week before taking it to Ford Garage to be serviced and inspected. It has high mileage. over 208,000 miles. The engine light was on the previsce owner said it needed an 02 sensor, upon them checking it needed 2 02 sensors and a drivers side air bag replacement. upon them checking the car fax at the Ford garage the service manager told me that the vehicle had never been in an accident or any reported damage. do airbags normally just go bad. I had to replace airbag so that it would pass West Virginia's state inspection. the service manager got upset at me when I asked why it needed replaced. he ever told me they would not do the work. But it needed done to pass the state inspection, I would just have to park it and forget about it unless I sold it to someone in a state that did not require state inspections like the man i bought it from in Ohio. I even asked if it could be a sensor or component that was bad instead of replacing the complete airbag. the service manager got very upset on me asking. so i told him to do the work so that i would be able to drive the vehicle. replacement and labor was over $1,000. I live on S.S and that's a lot of money. plus the 2, 02 sensors was over $600. Plus whether it maters , the evening before they picked up the vehicle the air conditioning worked great. have witness. the picked it up and drove it to the Ford dealership In Wellsburg , West Virginia which is a drive of about 8 to 10 miles. the service manger told me the car had no air conditioning working. This is very strange since the day I bought the car the air conditioning worked great. he told me he even had his supervisor check it. I have not been able to check the vehicle because I have been extremely ill since vehicle has been returned. I have not been able to check it , I haven't even been outside my home. all together, parts and labor an different items came to over $2,800 . was there ever a recall on the airbags during this time period its a 2013MKX
