Seat Broken problems of the 2016 Nissan Altima

I recently purchased this vehicle in February of this year. Upon driving a few times, the air bag sensor light appears and stays on my dash along with when I have a passenger in the car, the passenger air bag sensor does not turn off. It is now March and I still have the same issue. According to the carfax report I received when purchasing the vehicle, a maintenance check was conducted by the local Nissan dealer close to me in January, it only shows the current recall of a hood latch (20v315 - that apparently no part is available for). I was advised by a service repair representative that the air bag sensors under the passenger seat are broken and were not repaired during that maintenance check. I questioned as to why with no explanation given. I advised that this is a safety concern and should fall back under the recall from 2016 (16v244) with the service representative stating that it doesn't!! is it possible for this to be fixed under that recall or does a new recall have to be in effect?? looking out for the safety of myself and fellow passengers. Thank you from a very concerned vehicle owner.
