Passenger side front airbag sensor turns off airbag when an adult is seated there. this occurs almost every time i have a passenger in that seat. i can occasionally get it to turn airbag on by shutting car off and restarting, sometimes it takes 3 cycles of off/on. most times it still won't reset and my passenger has to move to a rear seat. this happens even with a 200 lb. man seated there. this is my 4th infiniti and they've all had this issue. infiniti should be held accountable and make needed repairs to the airbag sensor
