All of the buttons on my steering wheel including the horn stopped working. I hear a clicking noise when i turn the steering wheel and the passenger air bag light randomly goes on and off. This leads me to believe the clock spring is broken. If the clock spring is the problem, this could create an airbag malfunction causing it to not deploy when needed or randomly deploy while i’m driving.

While driving my SUV, I turned a corner and I heard and felt a wire or wires pull and snap inside the steering wheel. I then found that I could not operate any of the controls on the steering wheel and the driver side airbag light came on with a disabled message on the display. I think that it is the clock spring inside of the steering wheel that got caught up and snapped from me turning the wheel.
