Front Seat Belt Buckle Assembly problems of the 1997 GMC Safari

Safety belt in back of vehicle does not latch. Had repaired once. Also, seat latch broke.

My daughter was attempting to hook her seatbelt before we left a parking lot and the buckle literally fell apart in her hand. This was a rear belt with no doors nearby so it had not been damaged in any way prior to its failure. Our concern is that had we been in an accident it would not have protected our child. The dealer says that we are responsible for the cost of the replacement as well.
