There was a time when my airbag light would stay on, indicating a sensor identified a problem somewhere in the car. When this happens, the airbag is effectively disabled, meaning you are screwed if you get in an accident. Before I ever took it to a shop to get checked out, the light stopped staying on. Apparently, it is an issue with our cars that many have experienced. If it stays on when you drive all the time, it is worth getting looked at. Otherwise, it may disappear in a week.
