Re: Third row seat....seatbelt
Forgot to mention that I had ours out recently, and when putting it back in the ceiling, I noticed that it has to be pushed in all the way, and really doesn't have a "click" persay, but a definite push to the rear of the vehicle will allow it to snug into the holder, and shouldn't come loose. Make sure you push the little metal end of the buckle into the hole in the plastic holder, and that should solve your problem. If for some reason the plastic is broken, that could be the reason it doesn't snug into the holder....should be covered under bumper-to-bumper.....keep us posted.
