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.

The contact owns a 2021 Kia Forte. The contact stated that while his mother was driving at 20 MPH and attempting to complete a left turn. another driver failed to stop at a red light, as a result, the contact's mother was struck by the other vehicle on the passenger's side; however, the air bags did not deploy. In addition, the seat belt failed to retract. No warning lights were illuminated. The vehicle was towed to a repair shop for body repair but was not taken to the dealer or an independent mechanic to determine why the air bags did not deploy. A police report was filed and injuries were reported. The contact's mother did not initially seek medical treatment but was later treated by a chiropractor for back pain resulting from non-descript injuries sustained during the accident. The contact also stated that his mother had later been involved in 2 additional vehicle accidents during which the air bags again failed to deploy; no further police reports or injuries were reported. Following the third and most recent incident, the vehicle again was not taken to a dealer or independent mechanic for diagnosis though the contact's mother was informed by the body repair shop that the collision was insufficient to trigger air bag deployment. The manufacturer was not notified of the failure. The failure mileage was unknown.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Kia Forte Koup verdict →
