Owner report 11681852 · 2025-08-20 (August 20, 2025)

I own a 2025 Kia K4 that has experienced multiple serious defects since purchase, raising ongoing safety concerns. Within the first four months, my windshield has failed or cracked four times, with one replacement denied by Kia and paid out-of-pocket. The windshield continues to make loud cracking noises, suggesting a structural defect that has not been resolved. In addition, the sunroof does not open or close properly, and while Kia acknowledged the defect, they only offered a potential software adjustment that does not address the root cause.…

Owner report 11684275 · 2025-09-01 (September 1, 2025)

The airbags failed to go off. I think the vehicle is still available it was towed to Carroll's in Winslow Maine. By the airbags not going off it made the risk of injury much greater. Also lost control of the steering all together. Tried to swerve to miss an animal and the steering assist took over. Yes we have a police report stating that the airbags didn't go off. I am sure budget had their people go look at the car. No warning lights present.

Owner report 11684281 · 2025-09-01 (September 1, 2025)

There is a defect with the WINDSHIELD glass. The windshield glass gives off an audible "SNAP" or "POP" noise when the inside of the windshield glass experiences a stress crack. This is not a crack that can be felt from the inside, or the outside. It is actually inside the glass and it can only be seen when the sun hits the windshield a certain way. Eventually failure of the windshield is imminent. The windshield glass internally fractures under normal driving conditions. It happens commonly, and intermittently, probably at least once per …
