NHTSA Complaint #11681852 — 2025 KIA K4

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. The vehicle also makes loud, unpredictable popping noises from the dashboard, a problem that multiple other Kia owners at the same dealership have reported. The dealer confirmed that Kia does not have a fix and only offered to temporarily “push in the dashboard.” Furthermore, the seat cooling system has stopped working entirely without repair options provided. These defects compromise the safety and reliability of the vehicle, creating risks of reduced visibility, potential structural failure, and driver distraction. All issues have been reported and documented at Courtesy Kia of Brandon, FL, and confirmed by the dealer, but Kia has failed to provide adequate remedies. No warning lights or error messages appeared prior to these failures. I have also filed reports with the Better Business Bureau Auto Line, the Florida Attorney General’s Office, and Kia Customer Care, but no meaningful resolution has been provided. These ongoing unresolved defects indicate systemic safety issues with the Kia K4.
