“My ICCU failed while I was driving and I lost power while in a light controlled intersection in Chicago. The screen turned off and I could not see my speedometer or any driving information. I luckily was able to roll to the side of the road and park the car. My car could not change gears, doors would not work, trying to jumpstart the 12V did not work.”

NHTSA complaint #11706602, filed 2025-12

“While driving at speed, I heard a pop noise from the car. A few seconds later, I received notification to check vehicle electric system. The vehicle slowed down despite my increasing throttle input. I was able to limp to a parking lot where it was flat bed towed. This experience matches a previous issue I had when it was diagnosed with an ICCU failure with the same vehicle.”

“Regarding NHTSA Recall No. \/ MFR Recall No. : 24V-867 \/ SC327, I have contacted Kia America by email who is avoiding to take action in rectifying the SC327 defect. From March 11th to March 15th 2025 I have emailed Kia several times to address the issue of my Kia EV6 car, the lack of response from their side compels me to lodge a complaint with you. Please intervene in my case with Kia. Below is the latest correspondence from Kia.”

“The vehicle throws a charge interrupted error on any Level 2 AC chargers and stops charging within few minutes of starting charge. The charging occurs only for 10~15minutes and immediately stops. The issue has been persistent since 3-4 months now and consistent on every charging session. I have to unplug and replug the charger multiple times to be able to complete charging. This also happened to me on a DCFC 150kW charger as well.”

NHTSA complaint #11552504, filed 2023-10

“After driving my vehicle for a few minutes on my way to work my car lost speed rapidly, going from 40 mph to 25 then seconds later to 22 mph. I tried to accelerate; the car was unresponsive and would not accelerate over 22 mph. Dropping speed rapidly and suddenly during rush hour on a secondary road with a limited shoulder was unnerving as the slow response required waiting for a gap in traffic flow to safely turn around to head home. …”
