Shortly after purchasing my 2018 Nissan Altima (new), there was a recall concerning the passenger side airbag. I took the car to the dealer and had it serviced. Months later, there was a second recall and I took it back promptly; however, the dealer said that nothing was wrong. It was already serviced. I indicated that I had received a second notice. Some time passed, and the same airbag light indicator came on and stayed on. I took my vehicle back to the dealer. This time, they wanted to charge me thousands of dollars. I indicated that this is the same problem from the beginning and I was going to file a lawsuit. The dealer claimed to have fixed the sensor and told me it was a complimentary charge based on ‘goodwill’. The same sensor light is on again. I have had no accidents and I have not had my car serviced for any electrical issues. It was inspected and passed with a warning to get the sensor taken care of. The original dealer has now sold to another Nissan dealer. I need to be sure that I am safe should I have a situation where the passenger side airbag needs to deploy. This is not fair to me. I have never bought a used car and this is the first car I have continuously had unresolved issues with. Please advise.
