Latest K5 complaints
When driving on the highway a couple of hours from home we had noticed our check engine light had went on, immediately after our gas mileage had dropped significantly. Shortly after we had heard a loud pop and thought a rock had hit our car. We right away noticed our dogs crates were slanted and they were up and scared. I inspected to see why the crates were slanted and when I had turned around I had seen that that rear seats were popped up with a huge space inbetween them and the frame of the car. We immediately...

had gotten off of the highway and pulled over. With a quick google search as we were unsure what happened we had realized it was from the Kia k5 recall and our car was no longer safe to drive. We had to have a tow truck take us and our car to the closest kia which was still very far from home. This could have been much worse. Kia Riverside had seen my car to service it for the recall. They kept my car for hours and then said they didnt have the part to fix it, they had told me they ordered it. But after multiple calls i realized they did not care to fix my car. They were neglectful and this recall could have cause me and my family serious damage.
**2024 Kia K5 GT\-Line - Electrical Overheating and Burned Dashboard Wiring** My 2024 Kia K5 GT-Line, with approximately 112,000 miles, has experienced intermittent audio system failures. On November 9, 2026, I was informed by a Kia dealership that the AV unit was excessively overheating and that the dashboard wiring harness had sustained melted and burned wiring. The dealership technician described the AV unit as being so hot that he could "fry an egg on it." The dealership advised that both the AV unit and...

dashboard wiring harness require replacement. I am extremely concerned that this excessive overheating and electrical damage present a potential vehicle fire hazard, particularly because the original symptoms involved intermittent audio failures rather than an obvious warning of an electrical safety problem. I am requesting that NHTSA review this incident as a potential electrical safety defect and determine whether similar failures have occurred in other Kia vehicles.
The contact owns a 2021 Kia K5. The contact stated that while her husband was entering the vehicle, the rear seat was elevated. The contact stated that upon inspection, it was discovered that the fuel tank had abnormally expanded. The vehicle was taken to the dealer, and the contact was informed that the vehicle was unrepairable. The contact received notification of NHTSA Campaign Number: 25V794000 (Fuel System, Gasoline). The Kia Customer Care was contacted by phone and a case was opened; however, no further updates were provided. A loaner vehicle was provided. The failure mileage was approximately 91,435.
I am reporting a potential safety defect involving the fuel tank system of my 2021 Kia K5 LS. On August 17, 2026, my vehicle was inspected at Bayway Kia in connection with Kia recall SC356. The dealership documented the following on Repair Order #4972: "Recall SC356. Check and found fuel tank fail. Then open a Techline case." The dealership's documentation indicates that a fuel tank failure was identified and a Techline case was opened with Kia for further review. Kia America subsequently informed me that its...

preliminary evaluation found that the rear seat pan and strap deformation were consistent with the fuel tank expansion condition. I was advised that the vehicle was unsafe to drive. No repair addressing the documented fuel tank failure has been performed. The exact component failure and its cause have not been explained to me. Despite repeated requests, I have not received the detailed diagnostic findings, technician notes, photographs, diagnostic codes, or complete Techline case documentation. I am concerned about the potential safety implications of a fuel tank failure and the reported deformation of the surrounding vehicle structure, including whether the condition could create a risk of fuel leakage or fire. I am not claiming that a leak or fire occurred; I am requesting an independent safety review. The vehicle was inspected by Bayway Kia, and Kia America conducted a preliminary evaluation. The vehicle's availability for further inspection can be confirmed with the dealership. I do not know whether any warning lights or symptoms appeared before the inspection. I am requesting that NHTSA review this documented fuel tank failure, the associated deformation, and whether this condition may present a safety risk to occupants or other motorists.
The vehicle experienced a complete and catastrophic loss of drive power, rendering the care entirely undriveable. This failure perfectly mirrors the exact safetyhazard detailed in NHTSA Recall 22V760 regarding a manufacturing defect in the electric oil pump of the 8 speed dual clutch transmission, which triggers a fail safe mode and cuts all propulsion. Previously, the servicing dealership, Kia of Columbia ([[redacted]]), performed a transmission control unit software flash related to this recall. The dealership...

then reported the recall remedy as fully completed and resolved to both KIA America and the NHTSA database, effectively cancelling the active recall status for my VIN. However, the dealership failed to perform the mandatory physical inspection or complete unit replacement required for an actively failing component. They dismissed my ongoing complaints regarding transmission driveability, flasely blaming my driving habits. Because the software update merely delayed the inevitable mechanical failure of the defective factory pump, the transmission has now completely failed, leaving my family two hours away from the dealership. Th Dealership incorrectly and falsely reported a critical federal safety recall as "repaired" to the NHTSA while leaving a defective, hazardous transmission in my wife's vehicle, that she uses to get back and forth from her cancer treatments. I am requesting a formal federal investigation into the repair reporting pracices of Kia of Columbia, demanding the Kia America re-open this case to authorize a complete replacement transmission unit under the original saftey mandate.
