While driving to Dallas, I hear what sounds like the paper towel dispenser in public bathrooms go off over my left shoulder. Then I felt my seatbelt loosen up. I pulled it to make it tighter and the complete seatbelt came out. It will not go back in. While searching for answers, all I came up with is how to clean it. Has anyone ever heard of this and if so, how do I get the seatbelt to retract?? Thanks in advance!
