“I was backing out of my driveway and was putting the car in Drive when the airbag located in my steering wheel deployed without a reason. The car has not been inspected by anyone as of today. I was told there was a warning but that it was not of immediate attention in November of 2024.”
NHTSA complaint #11648715, filed 2025-03“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.”
