The backing on the 40 side of our third row seat detaches itself! The backing is intalled with "pins" that insert into the seat however the seats seems to be a little tight so when you move one seat against the other you can pop the backing off - ie fold the 40 part down when the 60 section remains up. It reinserts OK but afraid that if this continues eventually it will just be loose and won't stay tightly attached to back of the seat. Will discuss it with the dealer but not sure how they could move the seat to provide greater seperation. Anyone else have this problem? Otherwise we love the pilot - just took it across the Canadian Rockies and powered past more than a few SUV's climbing up some long grades.
