2022 KIA EV6 Electrical System Problems

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...

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...

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.

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.

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.

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...

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...

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

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.

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.

Car lost all power and came to a stop while backing out of a driveway on a residential street. It would not respond to any attempts to start it. None of assessories worked. It had to be towed to the dealership. The dealer said the 12v battery was at fault and had to be ordered from Kia. I was told the ICCU unit had failed and drained the 12v battery. It waited for the part from Kia. Then the ICCU needed to be replaced. This was in 2024. The part was not examined. There were no warning signs or symptoms. Had I been in highway traffic my life would have been in danger

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.

The ICCU failed and left me stranded in single digit temperatures.

ICCU failed. Level 2 charges didn’t work.

Electric car stopped working with home, (level 2 or AC charging), only level three or DC fast chargers. Took car to local dealership who confirmed the cars ICCU had gone bad, which is a known issue with this vehicle, and needed to be replaced. Since I had all the software recalls done to mitigate this matter Kia replaced it under warranty. There were no indication that anything was wrong with the vehicle until the first unsuccessful charging attempt at home.

The ICCU went out in my car. Fortunately I was at home charging and not on the road.

On last Feb-2025, Car stopped while driving, message pop up electrical problem, stop the car immediately, it did not have time to properly park, stopped in middle of the road and have to wait 3 hours for tow truck, car wont open or move, all electric dead. (ICCU, fuse and 12V battery replaced) on last week 01/26/26 at 64K miles, message pop up again on screen dash, electrical problem, stop car. i was able to drive at 30mph to dealer and leave the car. after 8 days on lot, i got a call from dealer, ICCU needs to be replaced, not sure when part will be received. Driving a rental while

ICCU failed while driving on freeway. Heard loud pop which dealership determined to be a blown fuse as a result of the ICCU failing. Car decelerated to 30-40 mph and stayed in this limp mode. Light on dash indicated an electrical system issue. Vehicle was towed to dealership and repair was made under warranty.

Vehicle failed to start (no power). Charged the 12v battery via wall charger and was able to start vehicle but was faced with numerous warnings, including low power mode, electrical errors and other warnings. Car towed to dealership and was found to have a failed ICCU.

Iccu failure

The AC charging for this car stopped working around [XXX]. After 3 trips to the dealership for repair I brought it back a 4th time and because the dealership was unable to repair it they gave me a loaner to use while they tried to figure out the problem. During this time they removed the entire battery from the car, dropped the suspension, experienced the car not being able to go into gear (reverse or drive), not hold a charge etc. The car has been 100% inoperable since [XXX]. Today, 01/27/26 the dealership phoned to let me know that a regional Kia technician came by and realized there was just one screw that needed to be tightened and now the car works perfectly and I can come pick up my car and bring the loaner back. There is no way I would ever feel safe driving that car again. Kia...

My 2022 Kia EV6 would not charge on my home Level 2 charger and potentially shorted my ChargePoint home charger due to a failure of the Integrated Charging Control Unit (ICCU). I tried to charge on a Level 1 charger and the vehicle would not charge and brought up a electrical error message. I then tried charging on a Level 3 charger which worked. I brought my vehicle to the dealership today and they confirmed that there is a problem with the ICCU. This is a serious issue that KIA/Hyundai has been aware of for several years and still has not adequately remedied. This failure can occur while driving so it could have caused an accident or left me stranded far from home. KIA/Hyundai should be forced to replace all ICCU units rather than releasing software updates that do not stop the ICCU from failing.

I have had multiple issues with the electrical system in this car. Even after recall and software update the iccu failed. Module 6 fuse consistently blows and I replace myself to keep my car working as close to the way it’s meant to as possible. The 12v battery has failed twice. The last time after a replacement. The system fails to maintain it. When the iccu electrical issue happens the car stops working completely. It is hobbled speeds as low as 15 and cuts off within minutes if you are dealing with this issue. The hatch will not open the car will not go into neutral to be towed so then has to be DRAGGED onto a flatbed to go to the dealership for repair. The repair often takes significant time.

Repeat failure of iccu/electrical system. Car fails to maintain charge in 12v over time. Something fails damages the charge. I replace the module 6 fuse regularly on my own because I was tired of taking it to dealer and paying ~$20 for a few extra fuses that cost almost nothing. The car was in turtle mode the next day after a trip. The car wouldn’t go more than 15 mph then shut off. You can’t start it to put in neutral to tow so they MUST drag it into the flatbed. You cannot access items to help you from the rear hatch. The car becomes a giant metal paperweight when this issue occurs an leaves you stranded and at risk of harm.

Widely circulated and well known ICCU issue leading to 12v failure. There is a recall on this, but people are being stranded and offered only part replacement. Kia should be responsible for corresponding costs associated with their defective units. I’ve had 2 bad ICCUs and the second one left me stranded. Unacceptable.

The car stop working with this message "check electric vehicle system" I towed the car to kia service. They told me nee to replace ICCU unit. They replaced it for free, but still didn't have a car for few days. No loaner car offered.

I am reporting a failure related to the Integrated Charging Control Unit (ICCU) on my Kia EV6 vehicle. The vehicle suddenly became unable to charge using Level 1 or Level 2 AC chargers. Each time the charging cable is connected, charging starts briefly and then stops within seconds with a “charging unsuccessful” warning. The issue occurs consistently across multiple chargers. However, DC fast charging (Level 3) still functions, indicating a failure specific to the onboard charging system. In addition to the charging failure, the 12-volt battery became abnormally depleted, which required external charging to prevent the vehicle from becoming completely inoperable. This raises safety concerns, as a drained 12-volt battery can disable critical vehicle systems. This appears consistent with widely reported ICCU failures affecting Kia EVs. The failure occurred without warning and has rendered the vehicle unreliable for normal use. Because the vehicle cannot charge at home or on standard...

ICCU failed preventing the vehicle from being charged and killing the 12v battery.

ICCU failure at 71k miles on 2022 Kia EV6. Owned for 46 months, original owner. 12 volt battery also died when 18 months old, which left me stranded and I had to be towed to dealership Never missed a service or recall update

Unsure exactly why it happened, but I was driving in my parent's neighborhood (25 mph limit), and I heard a pop, and the next thing I saw was an electrical warning message on my dashboard. That's when I realized the issue is with the ICCU.

Heard fuse pop in back of car immediately went into turtle mode with red check electrical system warning. Dealer diagnosed as bad ICCU which also drained the 12v battery. This recall should be left open for all these ICCUs keep failing and stranding people.

I was driving to work less than a mile away from my home, when coming up to a red light my car told me to find a safe place to stop. No previously warnings or other symptoms. Car just went from fine to nonfunctional in a matter of seconds. Once stopped, I had no power or any electronics. Not even hazzard lights. I was stuck at the intersection while I awaited a tow truck which had difficulty getting the car on the truck due to the complete electrical failure. Car was towed to a local Kia dealer who inspected it the next day and confirmed the ICCU was at fault. It was replaced in a couple of days and convered under warranty. 12v battery also dead but not covered by the warranty even though the faulty ICCU could have caused it to die early.

Vehicle alerted Electric Vehicle System problem on the dashboard. Dealer determined the ICCU and a fuse needs to be replaced again. Dealer has declined to replace the ICCU under the current recall stating it was already replaced 8 months prior. Vehicle is not usable in current condition due to a faulty ICCU.

After owning this car for about 3 years now I had the ICCU blow out on me at 53k miles right before thanksgiving. This prevented my car from Level 1 / Level 2 charging and would no longer keep the 12v battery charged. this made the car drive at limited speed as the 12v would drain. I had previously taken the car to get the ICCU recall early in the year and obviously that "software fix" did prevent this from happening. How am I supposed to reliably drive this car unless KIA/Hyundai actually redesigns the ICCU? This is something that needs a permanent fix or at the least a lifetime warranty coverage.

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.

Could not charge car. It kept saying Charging Interrupted. The failure was the ICCU

I bought my Kia ev6 new in October 2022, I have had problems with the charging system. I had the ICCU replaced on 9/12/2024 60,488. I just had to have it towed to the dealership because the same issue came up on 1/2/2026 92,943. It went into check electric system and pull over, then went into limp mode got it pulled over to the side of the road and it died. Dealership has it now and will give updates. I don't charge at DC only charge at home on a level 2 charger.

Heard a loud pop while driving , and then car immediately showed an electrical failure message and went into turtle mode. Diagnosed by dealer as an ICCU issue

Upon connecting a level 2 charger, I heard a loud POP, then the dashboard said charging failed, check Electrical system. From then on, the car would not be able to charge on level 2. The dealership determined that it was an ICCU failure, which is very well documented and experienced by owners in online forums. In my situation, no one was put at risk, however many owners have reported it happening while they were traveling at highway speeds. When this happens at highway speeds, it causes the car to slow down immediately, which is extremely dangerous. The part number of the ICCU is the same as the original, which means it's still the same part that could fail at any time. My car has been updated to the latest recall software to motivate the ICCU failures but it still happened to me. Please put pressure on Hyundai and Kia to...

ICCU fail at 58,000 miles. + the front fuse under the front seat. Rendered the car immobile and drained the 12 volt battery. Dealer replaced the iccu and fuse but refused to replace 12 volt, saying that it is covered up to 36k miles. They said ir can just be recharged. But since there repair took a long time, the battery was sitting fully discharged all this time. After that sitting period it would not charge back. So the fault resulted in a week of covered repairs and an extra 12 volt battery cost on an ev, not covered by the dealer.

The ICCU failed in my car while attempting to charge the vehicle while at home in my garage. This component has a known history of failure while driving and now that it has been replaced with an identical unit, I fear for my safety while driving since I live in a remote area and rely on the car for transportation in sub-freezing temps and winter conditions. While the dealer has replaced the ICCU, there is no acknowledgement from the manufacturer that the failure mode of this component has undergone any redesign or improvement to warrant trust that it will not happen again. It is a ticking bomb.

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.

The electrical system failed (dashboard warning light appeared while in park) and then a pop was heard (fuse bursting). Car could not safely drive. Dealer confirmed ICCU failed once checked at dealer. No prior warnings noticed and no issues charging with approved systems leading up to the failure.

Started car. Heard a pop in the back seat area and then an error message appeared on the dash.

I had an ICCU failure. There were no warning lights . The dealership initially could not find the problem but when I brought it back again they did confirm the ICCU failed and replaced it. Failure of this causes the car to stop driving and lose power causing you to stop on the road as well as be unable to charge the car.

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...

Not charging on Level 1, Level 2 chargers, only level 3. ICCU problem confirmed by dealer diagnostic even after recall software update was installed.
