ELECTRICAL SYSTEM
The Integrated Charging Control Unit (ICCU) failed twice within four weeks. The first failure occurred in March 2026 and was repaired under recall SC327 with a replacement ICCU and fuse. The second failure occurred April 7, 2026, approximately 12 days after pickup. Symptoms: Vehicle failed to charge overnight on Level 1 and Level 2 circuits despite being plugged in. Later that day, while driving, a “Check Electrical System” warning appeared on the dashboard followed by sudden loss of power and acceleration. Vehicle fluctuated between 25-45 mph and could not maintain speed. Vehicle was driven approximately 2.2 miles to the dealership under its own power after warning onset. Safety risk: Sudden loss of power and acceleration while driving created a hazardous condition for myself. Dealer confirmation: The authorized Kia dealer confirmed a DTC for battery overheating and acknowledged the ICCU coolant was not fully topped off after the first replacement, suggesting the recall remedy was incompletely performed. The vehicle has remained at the dealer unrepaired since April 10, 2026. Component available for inspection: Yes, vehicle is currently at the dealership. Recall remedy concern: The SC327 recall remedy did not resolve the ICCU failure. A second failure occurred within two weeks of the repair. The dealer’s subsequent diagnosis of owner-caused undercarriage battery damage is contradicted by their own signed inspection report documenting all undercarriage items as passed with no damage noted

This make/model has a known ICCU issue. Ours went out just after warranty expired and the cost is $4,000. The EU and some Asian countries have extended the warranty of this fault due to how prevalent it is.

ELECTRICAL SYSTEM
ICCU failure at 16k miles. The ICCU was replaced at the dealership on January, 29th of this year, so it is not available for inspection. The failure tripped a breaker at my home while it was charging possibly indicating a short circuit. The short circuit could have potentioally overheated and caught fire in my home. I took the vehicle to the dealership and they confirmed it was the ICCU and replaced it under warranty. I have a copy of the invoice received after the replacement was installed. I do not know what they did with the old ICCU after it was placed. There was no indication of pending failure that I noticed prior to this incident occuring.

ELECTRICAL SYSTEM
Electrical propulsion failure resulting in 3 tow-ins. Vehicle goes into limp mode, slows to 20 mph on highway and then stops after about 2 miles. The issue appears related to the ICCU, fuse and 12V battery failures. History includes 6 attached ICCU related Repairs. #1 ICCU updated under recall SC271 at 31,678 miles. #2 Then the ICCU was replaced under recall SC302 at 45,059 miles. #3 Then the ICCU was replaced along with fuse and 12V battery after on road failure and tow in at 52,296 miles. #4 Then the ICCU was updated under recall SC327. #5 Then the ICCU, fuse and 12V battery was replaced at 69,849 miles under recall SC327 after another on road failure and tow in. #6 Then there was a ICCU overheat and charging fault related to a bad ICCU coolant reservoir cap after a charging failure and tow in at 70,957 miles.

ELECTRICAL SYSTEM
The contact owns a 2022 Kia EV6. The contact received notification of NHTSA Campaign Number: 24V867000 (Electrical System) and the vehicle was repaired at the local dealer. The contact stated that four months later while driving 75 MPH, there was a popping sound coming from the rear of the vehicle. The message to "Check Electrical System" was displayed, and the vehicle unexpectedly decelerated to approximately 45 MPH. The contact continued driving and the message to "Stop Vehicle and Check Power Supply" was displayed. The vehicle decelerated to 5 MPH and failed to accelerate as intended. The vehicle was pulled over to the side of the road and inspected. All the doors were unlocked, and the vehicle then stalled. The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed and determined that the Integrated Charging Control Unit (ICCU) assembly and fuse needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 148,309.

The car has 41,000 miles and has experienced the second failure of the ICCU, so it will have a third unit in 3 years. The noteworthy issue is the risk associated with these failures. The unit failed on the freeway, and power was reduced to 20% (estimate), which put me and others in danger. This is apparently a known and significant issue with KIA. As a consumer, I am extremely concerned it will experience a 3rd failure, which could include immediate risk to self and passengers. How is this acceptable? Thanks for providing the forum to discuss.

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.

ELECTRICAL SYSTEM, ENGINE
I am reporting a recurring safety and reliability issue with my 2022 Kia EV6 GT-Line (VIN: [XXX] ). The vehicle currently has approximately 63,100 miles. The vehicle repeatedly displays a “Check Electric Vehicle System” warning message. This problem has occurred three separate times. On at least two occasions, the vehicle became undriveable and required towing. The failure appears to affect the vehicle’s electric powertrain or control systems. The vehicle is currently being taken again to the dealership (Lou Sobh Kia in Cumming, Georgia) for diagnosis of the same issue. This will be the third service visit for this recurring failure. Because this issue can cause the vehicle to become unexpectedly inoperable, I am concerned about the safety implications and believe it may indicate a broader defect affecting Kia EV6 vehicles.

Perhaps 1 year into owning this car the apple carplay connection started going in and out-- it takes perhaps 10 to 15 seconds for it to start working again. I've tried different phones and cords. This issue is getting worse, sometimes 6 times in a 20 minute drive. Now it goes out very frequently (though it is rare in the mornings for some reason). I have brought the car into a dealership and they cannot find any issue with the car. At the recommendation of the dealership I switched the cord to an official apple cord, but when I did this the connection would be lost and I'd have to reach down, disconnect the cord, and reconnect it to get the screen to come back on-- I have since switched back to an Anker cord. There have been many drivers with the same EV6 reporting this issue in Kia FB groups. Now that the car is about 4 years old, it happens very frequently (one time 6 times in a 10 minute span). The safety issue comes in as one, some people may be reaching to disconnect and reconnect their cord while driving, which can be a distraction and may lead to increase in accidents, two, if someone is on a call they may disconnect the cord and switch to speaker, which again is a distraction, and three, I have also been using the navigation system through the carplay, and when the map goes out my turn is going up it can cause me to hesitate on whether to turn or not (and perhaps if the screen comes on at the last minute, make a quick turn, which can increase risk of collision).

A warning came up on the dashboard to “Check electric vehicle system”. 12v battery light also on. Vehicle went into limp mode and drove at 45 mph max for a period of time, then dropped to 27 mph max. Inspections at Ziegler Kia in Holland, MI, found the ICCU was faulty and needs to be replaced. This vehicle has already had the ICCU recall applied, yet ICCU has failed again.
