NHTSA Complaint #11691058 — 2021 KIA FORTE

So i took my car to sands kia in surprise az about my seat belts. Both the front driver and passenger belts come unlatched while driving. They said out of warranty so i would have to pay or they will do nothing. This should be a Kia issue. Obviously a defect in the seat belts. I can be driving on freeway and multiple times they will come unlatched while driving. So instead of having both hands on the steering will. I have to fiddle around to get it to latch again. It is a legal requirement to have working seat belts and u feel kia should fix this issue. I told them this and that i didn't feel this was something i should have to pay for and the service writer just asked me if i was leaving then. Hope there is no accident because seat belts won't work and there will be a lawsuit.
