i have seen on alot of the other mustang sites that their airbag light have been coming on. This happend to mine a few weeks ago. I took it to the dealer and they replaced the airbag control module. thats what they said was defective on mine. So if anyone else is having this issue then it might be the same as mine and was fixed a day later. It has been almost a month now and the light hasnt come back on. I got no bs from the dealer about it even tho i didnt buy my car from them.
