Early inverter failure
400–616 miles
NHTSA complaints for the 2024 Kia EV6, grouped by the part owners named. Open a row to read what goes wrong.
Sudden loss of drive power is the main complaint. Most reports trace it to a failed ICCU. A "Check electric vehicle system" or "Stop vehicle and check power supply" warning appears, the car drops into limp mode, then dies, sometimes in a traffic lane with a nearly full battery. Several owners hear a pop first. One fire report describes a charred inverter at 616 miles. Dead 12V batteries, doors that will not open, and cars that cannot be shifted to neutral for towing also recur. Failures continue after the recall software update, and repairs can take weeks.
Drive power cuts out after a pop from under the car or behind the cabin. Dash errors follow, and speed is capped at 10 to 25 mph. Dealers most often find a blown ICCU and fuse. One case was a front inverter at under 400 miles. Some cars enter a "zombie" state: lights and climate work, but the car will not leave park, and the electronic parking brake blocks towing. A dead 12V battery alongside a full traction battery is another pattern. Repairs can drag on, with one car gone nearly 8 weeks.
In both reports, the car fails to slow when it should. In one crash, the car sped up at about 5 mph while pulling into a driveway instead of stopping for an obstacle. It broke through a gate and a garage wall. The other describes regenerative braking that would not slow the car on a wet road, then a pedal that needed full force before ABS engaged. Neither report includes a dealer diagnosis. With only 2 complaints, no wider pattern shows up.
Both complaints describe losing steering along with acceleration when the ICCU fails. One car lost drive power and nearly all control at 65 mph in rush-hour traffic, even though both related recalls had already been done. In the other, the owner could not accelerate or steer after the part blew. Both owners treat this as an ICCU failure, not a separate steering defect. Both also doubt that a replacement ICCU is a lasting fix. One injury is recorded.
In both complaints, the car keeps accelerating without driver input. In one, it surged from 72 mph to 90 within seconds on the freeway and slowed only when the brake was applied. In the other, it kept accelerating after the pedal was pressed fully and quickly released in NORMAL mode, nearly causing a rear-end collision in stop-and-go traffic. Neither report mentions a diagnosis or repair. With 2 complaints, there is no broader pattern.

I was coming home from work on 1/13/2025 and got an alert. a red circle saying pull over and check the electrical system. when i pulled over the best i could the car went dark. i called Kia for road assistance and they dispatched a tow to the dealer. the next day the dealer called and told me the ICCU needs to be changed and arranged a loaner car for me. The Dealer has been very helpful throughout this ordeal thus far.

Complaints for this year next to the average for the other model years, area by area.
The 2024 has the fewest owner complaints of the 3 EV6 years we cover, well under the average of the others. Newer years have had less time to collect complaints, so compare like with like.
Redesigns and mid-cycle updates change what can go wrong.
The 2024 is the third model year of the EV6's first generation (2022–2024).
Kia updated the EV6 for 2025, so a 2024 does not have those changes.
