POWER TRAIN
ICCU unit lost power and the car was unable to drive. Luckily I was parked when it happened but if I had been driving it would have been very dangerous. The part was replaced under warranty but they said it could happen again which really scares me.

ENGINE, FUEL/PROPULSION SYSTEM, ELECTRICAL 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.

ELECTRICAL SYSTEM
The contact owns a 2022 Kia EV6. While the contact’s daughter was driving approximately 40 MPH, the messages "Electric Failure: Stop Car Do Not Drive” and “12-Volt Battery Voltage Low" were displayed on the instrument panel. The vehicle then failed to exceed 20 MPH, causing the driver to activate the hazard lights while pulling over to a side street while driving approximately 5 MPH. On the side of the road, the vehicle lost power. The vehicle was left at the side of the road to be towed to the nearest dealer. The dealer was contacted and confirmed that it was a known failure with the Interior Command Centre Unit(ICCU), and that the ICCU might need to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 23,000.

vehicle will not charge properly due to ICCU failure, causing it to not charge the 12v battery which could have caused it to run out of battery at any moment causing the car to stop operating while driving which could have caused an accident, particularly because I do mostly highway driving. The dealership has confirmed the ICCU failure. While it supposedly got the previous recall fixes, that did not prevent it from failing.

POWER TRAIN, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
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.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
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.

ELECTRICAL SYSTEM, POWER TRAIN, ENGINE
Incident occured october 17, 2024. Was driving approximately 30mph on a local road when lights flashed to "check electric vehicle system". Was speed restricted to 25mph (on 45mph road) and was able to make it back home approximately 1 mile away. Car completely shut down in my street prior to making it to my driveway. It needed to be towed to the nearest dealership. No lights in dash working and flickering. Prior to this failure over the preceding several months there were errors where I would plug the car into Level 2 charging at home (9.6kWh) and the car would stop charging with a hot charging port approximately every 1 hour. I would unplug and replug in again. Charging would work. Level 3 was working just fine without problem. After going to the dealership it was deemed that the ICCU component needed to be replaced. After replacing car worked well and no charging issues occured.

ICCu failed. All the symptoms others have reported and discussed. (Reddit Kia subreddit + Kia Fotum). Sent home unable to charge. Kia claimed they could charge and wouldn’t do anything. After the second trip to the dealership they said “ it kick d out a ICCU code so we can replace it now”. They knew it was bad and the warranty protocol stinks. Software update did not prevent this. A fix and extended warranty should be required.

Kia 2022 EV6 41,238 miles. The ICCU failed and was towed to KIA dealership. It was covered only because we got the extended warranty. Was at 88% charge, dashboard lit up with the warning “Check electric vehicle system”. Loss of drive power increases the risk of a crash.

FUEL/PROPULSION SYSTEM
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.

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.

ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I am reporting a recurring safety defect. While driving the vehicle the Integrated Charging Control unit (ICCU) failed and caused the vehicle to lose power and stop in the road. I feel strongly that this ICCU issue and subsequent failure should be made into a safety recall. Kia / Hyundai / Genesis all share the same e-gmp platform and utilize an ICCU that fails and leaves motorists in unsafe situations. The ICCU should be recalled and replaced with a unit that works. The current recall remedies are only software updates, and are insufficient to prevent this safety issue and hardware defect, posing ongoing safety risk to drivers and other motorists. The ICCU should be a permanent fix, rather than just software patches that do not fix the issue. My vehicle had all software patches and was up to date, yet those were not sufficient to prevent this hardware defect and safety situation.

I completed recall in March of 2025 for the ICCU, it failed driving down a busy road in January 2026. Kia did complete the repairs, but only warranties for 12k miles. It seems from forums I am in that this is a common problem. It also caused me to be without transportation for several weeks

ELECTRICAL SYSTEM
This electric vehicle would not charge from a 120VAC or 240VAC source. It would charge using HVDC. It has been repaired by a KIA dealership and therefore the part is not available for inspection. I don't know that anyone's highway safety was at risk because the vehicle continued to operate normally and could be recharged, although not at home. That said, the failure presented as a dead-short to the EVSE, causing the circuit breaker to activate. If the home were improperly wired, I suppose an electrical fire could have occurred. The component that failed and was replaced is the "ICCU," the same component which was subject to a NHTSA recall for failing to maintain 12V power for charging the auxiliary battery and powering the 12V auxiliary equipment. The vehicle was inspected by a KIA dealer and the defective part was replaced. There was no advance warning. One day the vehicle charged normally. The next day, it did not. I am providing this information because NHTSA should have a complete a record of the KIA ICCU failure history as possible.

The car suddenly went into low power mode. It had to be towed to the dealer. The dealer learned the next day that the ICCU failed per the recall. However, while parts arrived a week ago, they do not have sufficient personnel to complete the work. They said it would likely be several more days. I was not offered a loaner. Were I not calling every few days I would not have any information. The dealer has never initiated a call to me for status.

The ICCU stopped working as we were driving on a backroom. The Check Electric Vehicle System" warning light came on, 12V battery discharge, and sudden loss of motor power. If this happened on the highway or while crossing an intersection, there is a high risk of getting hit by another vehicle by the car's sudden deacceleration. The same issue was replicated at the dealership and they are working on a repair or replacing the ICCU.
