Air Bag Light On problems of the 2014 Infiniti Q50

The passenger air bag sensor that controls the light showing if the system is on or off was serviced last year due to light being on when an adult was seated - recall 16v-244. The system worked for a couple of months and then stopped working, light remained on with adults seated. Sometimes the system worked and other time sit did not. On Tuesday March 29th, the airbag light was on for over 30 minutes and I stopped at the dealer to show them the problem. The light turned off just as the tech was looking at the problem. They suggested making a video of the passenger sitting while driving and the light being on. Got two videos of this situation. Going into dealer next week. Funny, today I get a letter from Infiniti about this recall and offering to fix and future problem with the air bag system. Seems odd that the recall fix did not work and now they will perform a "one-time retrofit to the OCS system. What is up with that, it should work as long as I drive the car. Car was in motion, adult passenger seated, OCS light was on, indication that system was off. Major safety issue if system is off and adult passenger is seated.
