When I said no one would guarantee a condition with your airbag, I meant that if the light came on and went out intermittently, The airbag would probably not go off unprovoked, and would probably work in a collision, but that you can't be sure under these conditions. If the light is on continuously, the system will be deactivated and the bag will not work. Due to liability concerns, if you contact a dealer about this condition, they will normally tell you to obtain service immediately. As to warranty coverage, If the car is under warranty still, the airbag system components are covered. Rewriting to clarify what was probably an oversimplistic post.
