While driving, car in motion, Front Passenger Seat belt Audio Warning Periodically goes off without reason. Indicating seat is occupied & seat belt needs putting on. When seat has been unoccupied / clear from any type of weight on seat to trigger sensor. Audio warning will continue until seat belt is latched over the empty seat. Local KIA Service Dept was informed & could neither confirm or deny its faulty behavior for it did not present itself during time of service. They said, wiring looked fine but did no further testing. To be honest they showed no interest into seeing any real importance for my concern for them to feel any further investigation was warranted. Its happened again twice since that service visit be it last incident Aug 7th. My concern is.... if there is faulty wiring or sensor signals being crossed somewhere, whats to say there is a passenger or no passenger in that seat, to ensure the correct signal is getting to the passenger side air bags of when to correctly deploy if an accident should happen with passenger in seat? This situ is only recent starting about a year a go. So something has changed from being fine for 2 yrs up to the last year that's now showing some kind of seat belt / sensor failure. I'm unfamiliar with how that wiring system works & linked within it for me know what other things I might need to pay more attn to, looking for other signs that could be saying is direct cause to the prob. Unsure if this a simple solution or is something that others are experiencing with this year & model car & poss be a Manufacturer Part Default

There is a problem with the passenger's seat belt. Often times the alarm goes off when no one is seating in the seat especially while driving. Also, when someone is sitting in the sit it overly locks no matter the speed of the car, thus causing the passenger to have to undo and redo the seat belt while driving. The seat belt has its own mind.
