Bought the car at 103500 and noticed shortly after purchase that the airbag light comes on in the instrument panel. After extensive online research and contact with the dealership, I discovered that the airbag light indicates the airbag may not deploy in the event of an accident. Since this appears to be a common problem, I would suggest that Mazda issue a recall to prevent further injuries, as there have already been a few that I've seen online. It is a severe safety issue.
