Front Seat Belt Anchorage problems of the 1998 Kia Motor Sephia

Just recently my sealbelt started failing. My wife noticed the problem a few weeks ago and now the belt fails almost everytime we put it on! the belt does click and the dash light does go off when we put on the belt. We will be driving and we will hear a click and then look at the latch on the belt and it has separated. This seems to be a very dangerous failure of the drivers belt. After the belt is latched and you give it a little tug it usually pops open.

Signal lights fail to work properly when in use during cold weather for 15 minutes or so. Sometimes this happens when it's raining. The dealer replaced the hazard switch and there have not been any failures since. Seat belts have been replaced 3 times. Brakes and rotors have been replaced 3 times. Windshield wipers failed prior to recall. Head gasket replaced at 3500 miles. Molding on the doors fell off and was replaced. Tailpipe was replaced due to excessive exhaust fumes.
