Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Unknown which component exactly as it does not throw a fault. I believe it to be transmission related as the behavior seems like a clutch to me, but dealership has not been able to confirm. Vehicle rolls freely in directions other than what is selected and does not respond to throttle input. Described the issue to dealer numerous times and they claim to have seen it. I do not believe they actually have. It is currently at the dealer for the fourth time about the issue. Currently claiming engine issues but the engine isnt even on when it experiences the problem. …”
NHTSA complaint #11685147, filed 2025-09“While approaching an intersection light, that was turning red, I suddenly heard the car beeping rapidly and all the red warning lights on the dashboard behind the wheel went off and the vehicle stalled. Luckily the intersection light was red, so everyone was coming to a halt. I do remember the dash board becoming blank, like there was no power. I had to turn the car's power ON button several times before I could shift into Drive. In the meantime, the traffic light turned green and I was still trying to switch the car to Drive mode. Finally it did and we drove the next 4 hours without issues. …”
NHTSA complaint #11527999, filed 2023-06“Main screen goes blank randomly and also randomly switches between android auto and normal. This disrupts navigation and other functions and is both distracting and disruptive to driving which is dangerous. Dealership said there is no fix from Kia at this point so advised to file a complaint.”
NHTSA complaint #11522778, filed 2023-05“The engine oil levels are dropping rapidly. This percentage number is displayed, making the driver think that an oil change is needed or that there is a leak. There seems to be a miscommunication from a sensor to the computer system. The mechanics at the dealer keep saying that nothing is wrong with the car. Because of the rapid decline of the engine oil levels shown on screen, one cannot know with certainty when and if there is a real oil consumption or not. The vehicle was inspected by a KIA dealer who so far, has not been able to diagnose nor fix the issue.”
