2018 KIA OPTIMA Seat Belts Problems

Passenger seat belt goes off when no one is sitting there.

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...

I WAS IN A CAR ACCIDENT AS I WAS DRIVING ON I65 AND MY AIR BAGS DID NOT DEPLOY AND MY SEAT BELT DIDN'T LOCK UP

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.
