Hey all, has anyone had an issue with the rear seat belts not ‘clipping’ in and staying in? One of mine is not working, I can see that as I push the buckle in, the latch that should hold the buckle in is not coming all the way out and locking. I suspect there may be some sand that has fallen down in there and it’s causing the issue as we recently took our MY to the beach. Having 2 kids and a dog on the back seat is always going to introduce sand, but I’m pretty anal about keeping everything clean, so it’s not like an unusual amount would have ended up in there. This is a pain as well, as it means i can’t clip two baby seats in and the dog. I have a service appointment booked for December 2nd for delivery issues, so until then someone has to miss out on a safety buckle, and I really like the dog so.... any advice or experience would be appreciated!
