What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
There were no warning lights, sounds, or messages displayed on the car's gauge cluster display, either for the initial loss of propulsion or for the restoration of propulsion. This caused a loss of traction when the car eventually passed through a patch of packed snow and ice.
Vehicle failed to start and a jump is required to start the vehicle for the first time on 10/6/2026. This has now happened numerous times and at times when the vehicle's power train batteries are charged.
I was driving in heavy rain on a busy highway (I4) and the lane assist pulled me off the road to the road hand side and then cut across all lanes of traffic to the left hand side. It also engaged emergency braking going forward when there was no reason to do so.
While driving a rented 2023 Kia EV6 on the freeway, the vehicle lost power and shut down completely, without warning, on multiple separate occasions during a single trip. This occurred at highway speed in live traffic, creating a serious risk to vehicle occupants and surrounding traffic.
Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown.
The ICCU failed. The vehicle suddenly stopped on the road, would not go into any gear and could not be moved whatsoever, was stuck on the side of the road in a dangerous position. Called roadside assistance, after a few hours the vehicle was towed to the nearest dealership.
After resetting the breaker and rebooting the charger, the EV6 would not start charging and displayed no “Charging started” or “Charging unsuccessful” message.\n\nI then attempted to charge using a portable Tesla Level 1 charger on a 120V GFCI outlet.
A small amount of snow / ice is sufficient to prevent the windshield wipers from returning all the way to the original starting position low on the windshield. For some reason this prevents them from functioning entirely - they just get stuck in a loop trying to go all the way down.
