Apparent issue over the years. Airbag warning light came on for no reason. Researched and found out there were recalls up to 2016 Altimas for the same problem. Dealer told me to bring it in and see if it would reset, but I would be charged because I was out of the mileage warranty by 6,000 miles. Car was 3 years old and never in an accident, but I would have to pay because of a faulty sensor and Nissan won't issue a recall for the problem
