I really feel for you. I have a 2007 Toyota Rav 4, and I've always wondered how someone could be so stupid as to back into the side of a garage door!!!! Shoot me!!! I have left and will leave the scratches on the side to remind me, and maybe humble me a bit!! Theresa
The hex head bolt loves to loosen. I pulled mine off and reinstalled it with locktite. I also check the torque every now and then. Check it brother, best find it now or at least get use to keeping an eye on it. In all the failures that I have heard of the bolt has fallen out or was hanging.
