Oct 19, 2026Fuel/propulsion system Fuel Tank has expanded and is in danger of exploding due to heat from exhaust system. My vehicle has been returned to a local dealer and Kia Corporate is willing to pay off my loan , but not compensate me for my down payment of $3500 that I put down 6 mths ago.
Apr 8, 2025Engine I bought a 2023 Kia K5 GT vehicle as a CERTIFIED PREOWNED from Rick Case KIA Sunrise, FL. I paid $30,000.00 + an extended warranty for about $4,000.00, traded in my vehicle (for $9,000.00) and put a down payment of $5,000.00. Within two days of buying the vehicle in April of 2025 my car was back at the dealership in the service department for transmission issues. My vehicle has had 4 total transmissions and it is 3 years old (original transmission, 3 replacement transmissions). SHOCKER - it is STILL having transmission problems. I have NEVER had a good drive in this vehicle. I filed a request for a buy back with Kia Customer Care and they told me I did not meet the requirements. My car has…
Sep 29, 2026Fuel/propulsion system I am filing this complaint regarding the handling of a fuel tank recall involving my 2023 Kia K5 GT-Line. On XXX, I brought my vehicle to Kia Rockwall in [XXX], after being informed of an issue related to a fuel tank recall. I was told that my vehicle could not be returned to me and that Kia would pursue a buyback instead. Before this incident, I had spent approximately $1,200 on repairs related to the issue, including replacing the charcoal canister. These repairs occurred the previous month. I am concerned about the circumstances surrounding the defect, the expenses I incurred attempting to address the problem, and the handling of the vehicle once it was brought in for the recall. I was…
Sep 13, 2026Unknown or other My 2023 Kia K5 GT has an intermittent and unpredictable audio defect which the vehicle suddenly and spontaneously produces an extremely loud static-like noise through all speakers in the car, immediately upon starting the vehicle. This is not related to the radio, car play, phone connection, weather, etc. Adjusting the volume dial does not effect the issue either, for example. Shutting the car off, stops it momentarily, but will return upon starting it. The only way to stop the issue is to either disconnect the battery or pull the main fuse to the dash, resetting the car. The issue has been occurring for 3 years. With multiple videos of the issue happening. The noise is loud enough to cause…

Aug 31, 2026Fuel system, gasoline The contact owns a 2023 Kia K5. The contact received a recall notification for NHTSA Campaign Number: 25V794000 (Fuel System, Gasoline). The vehicle was taken to a dealer, where the contact was informed that the recall repair was completed and the contact was provided a receipt. However, the contact later received several email recall notifications and verified that the VIN remained included in the recall three months after the repair. The dealer was contacted several times and eventually informed the contact that the recall repair had not been completed. The manufacturer was not yet notified of the issue. The contact had not experienced a failure.
May 31, 2026Electrical system The infotainment system in my Kia K5 has failed completely. The screen went black, causing the radio, infotainment features, and backup camera display to stop functioning. At times, the system will attempt to reboot on its own, but it does not return to normal operation and continues to malfunction. I have attempted to reset the system multiple times using the available reset methods, but none have resolved the issue. I took the vehicle to my local Kia dealership, where I was informed that the radio/infotainment unit itself is defective and needs to be replaced. The loss of the backup camera display is particularly concerning because it affects visibility and safety while reversing. I have…
