Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have persistent vibration issues with Kia ev9. It is very much a risk as it causes concentration issues while driving. My tires are worn out at less than 10k. Looking at the forum and reports a lot of folks who have EV9 are facing the same issue. Is there a investigation which can be looked into as this can be a safety issue due to vibration as well tired being worn as well.”
NHTSA complaint #11650900, filed 2025-03“Dashboard shows a message Stop vehicle and check brake system , vehicle doesn't pass over the 10 mph. On the KIA access APP I have all this 6 Diagnostic Issues : FR_CMR C28B981, FR_CMR C164286, ADAS_DRV C28B086, ADAS_DRV 28B986, ADAS_DRV C28B881, ADAS_DRV C164286.

NHTSA complaint #11623295, filed 2024-11“Our display/cluster, indicators, sensors, emergency lights stopped working in the middle of the ride. Major safety hazard on highway. Have to turn off the car and wait 30-60 mins for things to start working again. I know this has happened with others and to us before but in that case display stopped working the moment you turn on the car. Can't see the car speed, or any other things on display.”
NHTSA complaint #11617526, filed 2024-10“Car was new with 1,002 miles on odometer and with me for 3 weeks. The 12 volt battery died and needed to be replaced. This vehicle uses the 12v battery to start the electronics for the car which then enable operation of the car. The failure of this battery left the car without any power and it needed to be towed from my garage to the dealer. This is a common issue with Kia and Hyundai electric vehicles.”
NHTSA complaint #11629303, filed 2024-12“Vehicle suddenly slowed, with the same force at regenerative braking, to 30mph. Vehicle would not go any faster, changing drive modes, pedal to the floor, anything I tried did not work. Was in the middle of a 55mph road and was suddenly moving much slower than traffic with nowhere to pull off the road No warnings, no lights, nothing to indicate that I saw to show there was an issue. Dealership could not replicate and found no error codes.”
