Air Bags 3 Read
Since i bought car the passenger "air bag off" light is always on whenever my wife, who weighs 165 lbs, is a passenger - she does not have airbag protection. We normally do not have a passenger in the front seat, and never even knew if that was an option until my wife just sat in the passenger seat and pointed it out to me. This is while she was sitting with the seat belt while the car was moving at any speed.
The passenger airbag off light stays on while an adult weights more than 120 pound sitting on the passenger seat. The light won't go off while the car is moving.
Since i bought car at 96 miles and now at 3000 miles the passenger "air bag off" light is always on whenever my wife, who weighs 105 to 109 lbs, is a passenger - she does not have airbag protection. I took car to the service department of two independent dealerships 4 months apart..they both kept it overnight, tested it "thoroughly." their respective service managers said that the air bag met all specifications and that they "cannot adjust since it is set at the factory" i was referred to infiniti regional office and their representative said the same thing, but he added that given her weight if the air bag did deploy it would "be like a lethal weapon." i just read about the nissan "bag light recall" in today's paper. I am very uneasy...updated 10/01/15*bf
