“The ICCU in my Kia EV6 failed while driving. Thankfully I was not involved in a crash, but my speed was capped at 30 MPH, crawled back home, where the vehicle wouldn't start. I had to get it towed to the service center. All of this besides all recalls and software updates being addressed. There were multiple warning lights that went off during my drive: Stop vehicle and check power supply Check electric vehicle system”

NHTSA complaint #11662103, filed 2025-05

“While driving my Kia EV6 in the middle of a snowstorm, the vehicle experienced a sudden and severe power failure. I heard a loud popping sound from the rear of the cabin, after which the vehicle immediately entered reduced-power (limp) mode. Within approximately one minute, the vehicle shut down entirely and lost all propulsion and mobility. I was able to move the vehicle to a safe location only because I was not in traffic or on the highway at the time of the failure. …”

“I was on my way to the highway when about one mile from home when without warning vehicle went into Limp Mode. Acceleration suddenly dropped to 25mph. It was very dangerous trying to drive uphill on a busy road at limited power to get back to my home. Thankfully I was not yet on the highway. Dealer said that both the ICCU and fuse that were inspected a month ago due to a recall and found to have no error codes in January now need to be replaced. Parts on back order with no ETA.”

“The motor inverter for the rear motor failed while I was driving. The power cut out, and luckily I was able to drift over to the side of the road. On a highway, it would have been very dangerous. The dealer diagnosed the inverter issue, and said it needs to be replaced. The car has not been inspected by the manufacturer, the police, or insurance representatives. A warning message appeared the moment the power cut out. It said, Check electric vehicle system.”

NHTSA complaint #11533689, filed 2023-07

“Vehicle does not reliably handle the 12V battery well. Many times, I see it sitting at 12.8 VDC when driving the vehicle. On a ICE vehicle, the charging voltage is close to 14V when running/driving. On 3 separate occasions, when I tried to start the EV6, the 12V battery was too dead to allow the car to be started. Basically stranded. This can be life threatening if this occurs in frigid temps. Or a hazard to traffic if/when the car tells you to pull over safely, immediately . OK, I can block the box because my car died??? …”
