So I noticed the other day when my wife rode in the back it never registered that she was sitting in the seat and didn't have her seat belt on. Is that normal? I went ahead and checked this evening sitting in every seat in the back and none of them registered that there was somebody sitting in there not buckled up. It did finally register that someone was unbuckled but only after you buckled the seat belt and then removed it. Trying to figure out if I need to take it in to get looked at.
