What owners report

prior case 11708370 filed 1/2/2026 spoke with [redacted] 1/22/2026. Friday 2/6/2026 Shorkey Kia Wexford calls and tells me my EV6 is fixed I can pick it up. I go into the Kia App and still have the same 3 codes as before; P056216 VCU, C160404 FR_Radar, and C28B186 ADAS_DRV. I tell them later that day when I had time to open the app to make sure the codes were corrected, called them back and said until these codes are cleared, my vehicle is not fixed. Tuesday 2/10/2026 I get a called from same person at Shorkey Kia in Wexford, telling me my vehicle is fixed, I can pick up my vehicle, same person her name is Maggie. I told Maggie to hold while I bring up the Kia app, I still see the same 3 codes: P056216, C160404, C28B186. I told her the codes are still active, and as long as these codes are present, the car isn't fixed. …

While driving Friday 4/17/26, I heard a pop and the car displayed a message to "Check electric vehicle system." The car seemed to still drive so I drive it home. That evening the car would not charge. I called Jim Shorkey Kia on 4/18/26, where I bought the car, to schedule the car to be looked at. They told me to bring it in on Monday and they will try to squeeze me in so they can diagnose the issue. Later that morning, I took that car out and made it about a block away before the car displayed a new message to "Stop vehicle and check power supply." At this point, the car went into a limp mode, barely moving. I was able to turn around and drive it home. Had I been on the highway, I might have been put in a dangerous situation. Now that the car has been diagnosed, the service department called and told me that the failed component was the ICCU. …

I was driving my car on the highway, then I got the message heck your electrical system'for around a minute. Then there was a rumble or bang as if I hit something with the back, but the road was clean. Then the car started slowing down and I drove to the side. I got out of the car and saw white smoke coming from under the car in the back. I started opening the hood and trunk in the back to find out, where the smoke came from. It was nothing to see. Because it was an electrical car I assumed, that it could start burning, when it smells like smoke and looks like smoke. So I called 911 and told them, that I think my electric car is starting to burn, where I am and that nobody was injured. I took everything out of the car, closed the hood, the trunk and the doors and moved in a safe distance at the side. …

I leased a 2024 Kia EV6 on 1/27/24. On 2/22/24, twenty-six days after leasing the vehicle and an odometer reading of 616 miles, while on Washington state highway 903 there was a pop sound, the car slowed, and stopped displaying a "Check electric vehicle system" error. Due to the pop sound, we pulled over and barely made it off to the side of the highway before losing forward momentum. If this happened on a crowded freeway, the vehicle could have been disabled in a traffic lane. After 39 days, the dealer's service department found that inverter was "burnt and charred showing evidence of a fire in the system" and that the fire "potentially damaged the rear drive unit".
