2025 Kia K4

The contact owns a 2025 Kia K4. The contact stated that after driving for approximately 40 minutes at speeds between 55-75 MPH, the TPMS warning light started flashing, with the message "Check Tire Pressure" displayed. The vehicle was taken to the dealer three times. On the first visit, the dealer was unable to duplicate the issue. On the second visit, the dealer diagnosed the vehicle with an electrical system failure and reprogrammed the TPMS; however, the failure persisted. On the third visit, the dealer was unable to determine the cause of the failure, and the vehicle remained unrepaired. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 800.

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.

Bought my Kia k4 2025 in February at DTLA Kia and the experience has been [XXX]. The first day driving I went up near dodgers stadium , immediately had a burnt smell. I disregarded it thinking maybe its fresh paint burning , WRONG. Till this day 4 months later my tail pipe throws a musty smell. Issue number 2 , the hesitant gas pedal. Who knows what it is maybe fuel system , transmission but daily and I mean DAILY my accelaration is poor,jerky, struggling and overall doesn't work. It has its good mornings but once I'm on the road for more than 10 minutes its back to the struggle. I've had my K4 serviced twice at Dtla service, they never once test drove the car because I was tracking the GPS almost all day for the three days they had it. Once I got my car back it tooks about 45 minutes the service advisor Jeffery Montoya was so lost on where my car was, I had to ask and ask and ask finally the guys who are out front welcoming you helped me and brought my car. That was my decision to never go back to DTLA service. Next took it to Van Nuys Kia waited to weeks from my appointment because they are moving. Finally they kept it for three days they still werent able to diagnose the issue and repair it. Modesto the advisor there said " we can't duplicate the issue''. Some how they made me pay $82 because they supposedly found plastic bags stuck to my exhuast. [XXX] I even told him I don't want it cleaned and he said oh well you authorized the diag so you have to. He reported that info to kia Corp which got my case closed and said the car works fine. NO it does not work fine. Never going. Now today [XXX] I was parking arriving somewhere the k4 said engine off shift to P while ringing the alarm from the dash. I have it on film. Second driving down [XXX] and boom car engine shuts off while car are behind me. I had to shift to p then turn the car off. Turned it back on while getting honked at and that was that. $700 a month for a lack of urgency to help me. Boo Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
