On Sunday, October 4, 2026, the vehicle lost drive power while I was operating it. At the same time, steering became extremely difficult and the brakes required extraordinary physical force to apply. I had to use all of my strength to safely bring the vehicle to a stop. At that point we were stranded in the #2 lane of travel. This was not a minor inconvenience or an isolated warning light; it was a serious roadway safety event. Had my wife been driving, I do not believe she would have had the physical ability to safely control and stop the vehicle under those conditions.

I got into my car in a hurry i put my car in drive as i was closing my driver's door and took off and because the door wasn't fully closed the parking brake engaged itself but the power over comes the parking brake, when i let off the throttle the rear wheels locked up causing the car to slide out of control. I pushed on the throttle again to unlock the rear wheels causing me to swerve in the other lane and almost crash into an incoming car. I tried to turn off the brake and could not without stopping the car so i had to skid out of control again stopping to turn it off.
Steering rack need to replace after drive almost 1900 miles. It has knocking nosie when turn the wheel, the car had been in the shop for three weeks.
Kia has a known ICCU issue with several of their electric vehicles. Mine went out yesterday creating an extremely dangerous situation on the road. After it blew, I lost the ability to accelerate or steer. This was obviously very scary for me and the drivers around me. I feel very lucky to have not been hit by another car. Although Kia is replacing these, this does not guarantee a fix. That is to say, the ICCU has the potential to blow again after replaced because the core issue is not something that Kia group has...

reengineered. I should not have to fear getting into my vehicle and wonder if it will blow again. I hope the government steps in and conducts an investigation into this. It's only a matter of time before someone, unfortunately, will lose a life over this.
My 2023 Kia EV6 experienced a sudden ICCU and 12-volt system failure while traveling approximately 50 mph. Without warning, the vehicle instantly lost propulsion and all electrical power. This included loss of steering assist, braking assist, hazard lights, shift capability (unable to shift into Park), and even the ability to lock the doors. The failure effectively "bricked" the vehicle in motion. I was only able to get the vehicle off the roadway because the road happened to slope downward into a nearby lot....

Steering required significant physical effort, the brake pedal went completely hard ("dead"), and the vehicle offered no functional parking brake or Park engagement once stopped. Because I was on a hill, we had to allow the car to roll to the bottom until it met a curb to prevent movement. After power loss, the doors could not be locked at all. This type of unrecoverable electrical failure creates an extreme safety hazard for the driver, passengers, and surrounding traffic. There is no pre-warning and no diagnostic indicator. The ICCU fuse appears to fail spontaneously and renders the vehicle uncontrollable in several critical respects. This is not an isolated issue. ICCU failures have been occurring across the Kia EV6 and Hyundai Ioniq 5/6 platforms for more than three years, including on brand-new 2025 models. The persistence of this defect across multiple model years indicates that the underlying design or component defect has not been resolved by the manufacturer. Given the suddenness of the failure, the total loss of vehicle control systems, and the long history of similar incidents reported by other owners, I am now hesitant to drive the vehicle due to the unpredictable and dangerous nature of the defect.

risk of multiple crashes, this could happen to anyone with the same car and especially concerning because our car had ALREADY been serviced in the 2 previous NHTSA recalls (see above) for the very issue (ICCU) that impacted our car nearly resulting in a catastrophic outcome. The confirmed failed ICCU component has only been inspected, and confirmed failed by the KIA EV certified technician at the Modesto Ca Kia dealership. Since owning the car [[redacted]] a yellow 12 volt battery lamp indicator, not a warning light, on the front dash would occasionally be lit randomly while driving or parked. Just moments before the sudden loss of power and control numerus warning lights and messages were appearing and the displays were flashing on and off. We had absolutely no: warning lamps, messages, symptoms, nor any other issue whatsoever with our car prior to this sudden failure while driving on the highway.
