The front bumper sensor is detecting things in the road that aren't there and automatically applying the brakes on my car. when this happens, there's a loud almost grinding sound and the car brakes very hard. the other issue i'm having is the car will sometimes detect someone in the passenger seat when it's empty and turn on the buckle seat belt light and turn off the air bag off light for the passenger seat.
I had an accident on july 31st, 2019 where my car was totaled and the motor was lost completely. my airbags did not deploy and the nissan system stated, 'refer to owner's manual.' thankfully i was wearing my seatbelt and only had minor scratches and bruises.
