Almost recessed, like these in our 2021 Trailhawk (leather seats)?The slot is almost recessed and difficult for an adult to buckle.
Yeah, the tops of the latches are about flush with the seat surfaces. But I just tried one of the seatbelts, and it snaps in just fine. And pressing the red tab down unsnapped it quite easily.
Wife occasionally rides in the back, and she says she's never had any problem with the seat belts.
Did your latches maybe somehow sink down farther, below the seat level?
