Verbatim excerpts from NHTSA complaints, by component

Engine

102 reports1 crash2 fires
“At around 103K miles, I took to the dealership for a multipoint inspection for knocking when braking and my forward collision/lane assist systems going offline mid drive. I learn I have to replace my axle, despite replacing my axle in sept 2025. I return a week after due to the red oil light blinking on randomly, and when I checked the oil myself it was dry. The braking and assumed wiring issues remained. I find out that my oil is low despite an oil change July 16th 2026. It is October 8th 2026 as I type this. I am doing an engine flush in hopes to improve oil consumption, but i have since learned that my engine may fail from these other Kia stories. I have not stalled or had engine failure yet but now I am worried about having to sell my car to avoid having to keep replacing the same flawed parts over and over, or worse injuring myself while driving it. I was hoping to take a trip but now I have to rent a car and play another 1,600 dollars for the engine flush which I have no guarantee will actually work. I am disgusted, and there should be consequences for KIA (and many other companies) for taking advantage of their customers. I need a new car now!”

Power train

27 reports1 fire
“While driving to work, my 2020 Kia Optima suddenly lost engine power and went into limp mode in the middle of the highway, leaving me stranded and creating a severe safety hazard in traffic. The check engine light immediately started flashing and displaying diagnostic code P1326 which indicates an abnormal engine and/or a catastrophic rod bearing failure. This problem has been confirmed by the Kia dealership along with a 3rd party auto repair shop. However, Kia is refusing to cover the inspection, diagnostic, or any repairs due to the vehicle not having any open recalls, having more than 100k miles and the model of my vehicle despite this being a well known and documented manufacturing defect issue to these engines. The vehicle is currently available for inspection.”

Electrical system

14 reports1 fire
“On August 20, 2026, while my minor son and I were inside my 2020 Kia Optima LX, strong burning odors and fumes entered the passenger compartment through the HVAC vents. No dashboard warning lights or messages appeared before or during the incident. Although no visible flames were observed, I suspected an electrical component was overheating or melting, creating a potential fire and respiratory hazard. My son has asthma and experienced coughing and shortness of breath throughout that day, requiring use of his prescribed rescue inhaler. Neither of us received immediate medical treatment. Due to safety concerns, I had the vehicle towed to R&E Auto Repair on August 21, 2026, rather than risk driving it. The independent repair facility documented suspected melting of the HVAC temperature control unit and identified the blower motor resistor as a possible contributing component. Video evidence of the suspected damage was obtained. I formally reported the incident to Kia Customer Care on September 1, 2026. The vehicle was delivered to authorized dealer DeMontrond Kia on September 23, 2026, for further inspection. Despite the independent findings, Kia's dealership…”
