The ICCU failed which was part of the recall. Kia is unwilling to honor repairs beyond the 100,000 mile warranty which is unacceptable because there is still no resolution and it is subject to potential future failure. I need an extended warranty.

My car was / is one of thousands of Kia cars based on the eGMP platform to experience an ICCU failure. This is believed to be a design issue. While the repair was covered, reports indicate that the problem is not solved and will re-occur in time.

ICCU issue. Car showed zero percent battery after charging all night. No warning lights no errors

NHTSA complaint #11724240 — an unverified report by a vehicle owner.

FUEL/PROPULSION SYSTEM

When attempting to level one charge the vehicle at home, the car returned a failure to charge error and would not charge. This was attempted several times using different outlets and the same error occurred. The car was brought to Gettel Kia in Bradenton Florida. The dealership confirmed that the ICCU had failed,. They did not have the part and apparently it is on backorder. The repair is being covered under warranty, however, it is not being considered a recall, despite many other Kia EV6s having ICCU failures. The ICCU failures are extensive and need to be further investigated by NHSTA and a full recall for all Kia EV6s should be ordered.

FUEL/PROPULSION SYSTEM

Persistent ICCU failure causing charging interruptions, “Check Vehicle Charging System” → “Stop vehicle and check power supply” warnings, low 12V battery voltage (down to 12.1V), and risk of power loss/strand. Kia Connect sent “Charge Interrupted” alert during a session that reached 99%. Multiple prior recalls/attempts failed to resolve (Sep 2023 TSB ELE291 BMS, Jun 2024 SC271 ICCU SW, Jan 2025 SC273 VCU SW, May 2025 SA5999 limp-home logic, Sep 2025 dead 12V stranding). Towed Feb 2026 after stranding; dealer confirmed ICCU failed (DTC P1A9096), replaced ICCU (P/N 36400-1XFA0AQQK latest revision), fuse, and SW update under SC327 (24V-867). Repair completed same day (Feb 24, 2026), but dealer skipped charging system test and filling coolant. Safety impact: Stranded wife twice (dead battery and iccu failure), tow required, potential sudden power loss while driving. Report purpose: Document recurrence despite multiple recalls; seeking NHTSA tracking for effectiveness of SC327 remedy.

The ICCU system in my 2022 Kia EV6 failed for the SECOND time on the highway. The car threw an error telling me to "Check the electrical system" and "Pull over safely immediately" or something similar. Had I not made it to the shoulder, I would have been completely stranded in the middle of the highway, creating an incredibly dangerous situation. This is the second time this has happened with my EV6 in less than 50,000 miles on this car. I had to call a tow truck. I confirmed with the Kia dealership the ICCU system had randomly failed and was required to be replaced *AGAIN*. My wife was in the car with me and was freaked out. She doesn't feel safe in it because there's no rhyme or reason to when it happens. KIA says it is a known issue, and confirmed it was the second time this has happened to my car. No symptoms prior to it happening. We were just driving and then suddenly the car lost power and the warning displayed on the dash.

While driving in traffic I heard a pop, then the "Check Electric Vehicle System" warning came on the dashboard. After a minute or so the dash warning changed to "Stop Vehicle" and the car limped home but at a lower speed. This matched the description I had seen of ICCU failures on Kia and Hyundai EVs. Dealer confirmed this was in fact the issue, and I had it replaced under warranty. This was a safety issue for me and my family because when it failed I was driving in traffic on a four-lane road at night, in <40-degree weather, and it requires a tow to the dealership for repair. Although I now have a new ICCU, I am also now concerned that it might happen again. The vehicle has not been inspected by police, insurance or manufacturer that I'm aware of.

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.

Integrated charging control unit (ICCU) failed. While my failure prevents ac charging, the unit is could also fail causing the 12v battery not to charge and the car to power down while driving on the highway. There were no indication of part failure.

This electric vehicle failed to charge at level 2 charger at home. It charged at level 3 fast chargers however it registered a full charge at 125 miles and the level of charge in % and miles remaining fluctuated with sudden shifts. There were no warning lights or other signs of problems. I took it to the dealership who wanted me to keep driving and wait a week for an appointment. I knew that this could indicate an ICCU failure for the second time and insisted. Also asked that charging port and 12v be tested It was the second ICCU failure which can lead to a dead stop without warning in traffic. This is the second failure in this car.

I was driving and experience a loss in power and got the Check Electrical Vehicle System error message. As I was trying to get to safe location to stop, I got the Power Limited warning message and lost even more power then got the Stop Vehicle and Check Power Supply warning. I did not have any warning lights prior to this happening. I had my car towed to a KIA dealership for inspection and am waiting for their findings. It was at the KIA dealership 12/22/2025 for the latest safety recall update.

FUEL/PROPULSION SYSTEM

Bought this car in 2022 and had no problems until 1/2/26. Car was charging at home and suddenly stopped. Got a check electrical system warning light. Took it to the dealer to get checked out and the ICCU needs to be replaced. Despite everything online saying that it is covered on the 10 year/100,000 EV warranty, they are denying that it is covered under warranty. They say it is covered by the basic 60,000 mile warranty which I am a whopping 8,000. There has been multiple recalls on the ICCU, all software because Kia can't be bothered fixing their bad designs. Getting rid of this junk car and never buying a Kia again as I will not trust my life and safety with such a horrible company that doesn't care one bit about it's customers.

FUEL/PROPULSION SYSTEM

The ICCU charge control unit for Kia electric vehicles that immediately depletes the 12v battery & significantly reduces motive power forcing you to pull over with no countdown to how long one has in terms of distance or duration. This uncertainty is absolutely unsafe as you cannot know how long it is safe to keep driving before the vehicle ceases to move. This ICCU failure has been affecting several 2022 onwards Kia vehicles & even replacing this component does not guarantee this failure will not recur & needs serious action & accountability to Kia.

While driving, the car all of a sudden lost power - forcing me to pull over. If this were to happen while on the freeway, a crash would have been imminent. This is a known issue with kia/Hyundai EV's where the ICCU fails and causes the vehicle to lose power suddenly.

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.

FUEL/PROPULSION SYSTEM

In November 2024, my 2022 Kia EV6 became suddenly non-drivable due to electrical failure consistent with a repeat ICCU/12-volt system malfunction. The vehicle would not start or maintain normal electrical power and became stuck in accessory mode, creating a loss of propulsion and complete loss of transportation. This vehicle previously experienced an ICCU failure earlier in 2024 that required dealership repair and battery replacement. After that repair, the vehicle again developed electrical failure symptoms, including loss of 12-volt power and inability to operate. Due to the unsafe non-drivable condition, Kia Roadside Assistance directed and arranged a tow to a Kia dealership. Upon arrival at the dealership, new undercarriage and wheel-well damage was documented within approximately 90 minutes of drop-off. This damage was not present prior to towing and is located where tow equipment attaches. The vehicle remains in the possession of the dealership and is available for full inspection. The electrical failure created a safety risk because the vehicle became immobilized without warning and could not be safely operated. There was no advance notice or driver-caused event. The failure resulted in complete loss of vehicle function. The vehicle has been inspected by a Kia dealership, and I have been working through Kia corporate and roadside providers since the incident. The vehicle remains out of service with unresolved electrical issues and unresolved damage resulting from the manufacturer-directed tow.

Once again, the ICCU on the car failed requiring intervention / towing. This is the second outage of the ICCU. This issue happened in early April 2025 (April 8th I believe). My car was parked at work. I entered my car after work and turned on the car. I heard a pop from the rear passenger side identical to the issue as it had happened last January (2024). Shortly thereafter, the check electrical system warning came on. I briefly attempted to drive car to move it to where would likely be an easier spot for the purposes of towing (one parking lot over that is not gated). During that brief drive (roughly 1/4 of a mile), the car immediately began issuing warnings requesting that I pull over and stop. I entered the nearby parking lot and parked the car where it was towed the next day to the dealership.

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.

My EV6 lost power while driving on a busy street. It went into 'Turtle Mode' which allowed me to pull off onto a side road and then all power to the car went out and the car stopped on the side road. I was honked at a couple of times while trying to get off the busy street. The tow truck driver put a power pack on the car and shifted it into neutral and was able to move the car. The dealer diagnosed this as an ICCU failure. The part required is on national backorder with no delivery specified.

On 01/19/2025, after charging my vehicle to 100% using a Level 2 Charger, while driving, my vehicle displayed several warning notifications on the driver display, including "12 Volt Battery Low. Stop safely", "Stop vehicle and check power supply" and "Check electric vehicle system", shortly after I heard and felt a loud thump/pop. I returned home and powered the vehicle off. I and was able to drive the vehicle to the local Kia dealer the next day, less than 1 mile away. The vehicle had reduced power and multiple warnings advising to slow or stop the vehicle. On 01/20/2025, Geweke Kia advised the ICCU had failed and thet it was placed on order, with no ETA for the part.

FUEL/PROPULSION SYSTEM

On multiple occasions, while driving on the freeway, the vehicle experienced a clunking noise and complete loss of propulsion. Safety was put at risk as the vehicle had to navigate off to the shoulder of the freeway at a speed significantly slower (due to no acceleration available) than traffic with reduced braking capability. Once on the shoulder the vehicle needs to be turned off then on again then it functions as normal. Due to the intermittency of the issue, the dealer was not able to reproduce the problem, therefore they will not fix it. When the issue occurs, there are no warning messages on the display. The dealer has stated there are no error codes stored in the computer. This issue seemed to go away after an ICCU fix was applied, but came back after the ICCU recall was recently applied.

On April 13, 2024, when I started my vehicle, the instrument cluster immediately flashed the following warning msg surrounded by a flashing red circle: 12V Battery Very Low Stop Safely I turned the vehicle off, waited a few seconds and when I started it again the message did not appear. I contacted KIA USA and received a Recall Inquiry Case #. On April 18th, when I started my vehicle the same 12V Battery Very Low, Stop Safely msg displayed. It did not disappear upon restarting. Within 5 mts ALL the electrics were dead, including the instrument cluster AND the parking/emergency brake control AND the Vehicle Start On/Off button. I am very fortunate I was not driving on the highway when this occurred. Ditto for other drivers. My vehicle had to be towed to my dealer/service center. The tow service jumped the 12V battery and was able to drive it up on the flatbed. Today (April 23rd), my dealer/service center representive informed by the 12V battery tested okay, and the vehicle diagnostics they ran have not revealed any issues with the vehicle electrical system. They have been unable to reproduce or confirm the problem so far. My vehicle is still at my dealer/service center. What occurred is identical to the issues identified in the NHTSA Recall No: 24V-200 & KIA Recall No: SC302.

Was driving to go pick up one of my kids later at night. Was roughly 1/2 mile from home driving about 40 mph when I heard a pop / noise on the rear passenger side. Was unsure if I had rolled over something or what. Shortly after that (few seconds later), the "Check Electrical System" came on. Since I was close to home, I elected to turn around to go home since I could conduct a fairly easy turn around near the sub-division. Before I did that, the car then noted "Limited Power" and came up with the Turtle icon. The speed was restricted to 25 mph. This continued for roughly several hundred feet. At that point, a second warning noting a critical issue came up and the speed was further restricted to 12 mph. I was able to go through the 4-way stop sign, continued to drive under the restricted speed. I was able to turn on my hazards and wave several people past me as I drove extremely slowly home (12 mph on a 35 mph road). I did arrive to my house and pulled up into the driveway where I was able to park the car. The vehicle was at roughly 65% charge when I had started the trip. As per the recommendation of the dealership, I had the vehicle towed using Kia's Roadside Assistance to the dealership the next day. The vehicle was unable to start or even turn on. The tow truck was able to use a battery pack on the 12V battery to be able to activate the car to shift it to neutral for towing.
