Passenger from seatbelt has always been hard to get to engage and clip and would sometimes come undone while driving. Now the drivers side front is coming undone while driving even after assuring its secure before driving. Rear ones are now having same issue. I took it to the dealer and they said they needed replacement but not under warranty even though it has always been an issue. I didnt report it before the warranty expired but it has gotten much much worse and is totally unsafe to drive if it comes undone while driving. How is it supposed to work in an accident?
