The passenger airbag light is constantly on. When no one is sitting on the chair, the light states that the air bag is off and when someone is sitting in the chair, the airbag light states that it is on. I just purchased this used car a month ago from a Toyota dealership. Two weeks in with no accident whatsver, the problem had occurred. I noticed the airbag light turned on when I first purchased the car but it would quickly turned off completely after a while.
