NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2022 Kia EV6. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
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.
ICCU failed after 49,059 miles. Levels 1&2 charging do not work. I must use DCFC to charge the car.
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
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 contact owns a 2022 Kia EV6. The contact stated that while driving approximately 64 MPH, the left side of the steering wheel seized, and the vehicle aggressively jerked to the left into oncoming traffic. The message “Smart Cruise Disabled” was displayed. The contact was able to quickly regain control of the vehicle. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 65,300.
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.
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.
Driving down highway and check electrical vehicle system came on vehicle said pull over as soon as safely possible EV six started to go into turtle mode slow down to half speed then quarter speed before I was able to pull it into a safe spot took it into dealer after having it to be towed ICCU failure and they are ordering a new part for replacement. Also drained the entire 12 V battery.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
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).
The ICCU failed and had to be replaced. This is a known issue.
While driving the vehicle a short distance, I heard a loud pop from the back seat. The car immediately warned of an electrical system failure. The issue and symptoms are consistent with ICCU module failures, reported across the kia/hyundai egmp platform. My safety was put risk, because I was stopped in heavy traffic when this happened and could have been stranded far from home with no ability to drive the vehicle more than a couple of miles at most. The warnings started immediately after the pop I heard.
my 2022 ev6 iccu went bad at 106,000 miles. I took it to the dealer at 99,000 for iccu safety recall . the dealership did not replace the iccu at the safety recall . the dealer wants me to pay 4000 dolllars to fix it....they should have replace it at the safety recall. kia goose creek, south carolina
I was unable to charge this electric vehicle which I normally do almost once or twice a week using my home level 2 charger. It also did not speak the message that "your vehicle is being charged" which it normally does when I charge the vehicle. I tried multiple times. Then I got into the vehicle and saw that it was giving me the following error messages (pics included below) upon trying to start it. 1. "Check Electric Vehicle System" 2. "Battery Discharge Warning - Please use the vehicle after starting the vehicle". However the vehicle would not start and then it went went totally dead. Kia was kind enough to tow it under warranty to Century Kia in Tampa, FL as well as now they are trying to identify the issue. Kia was also kind enough to provide me a rental via Century Kia which I appreciate.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 failure. It blew up my home charger and shorted out. Would no longer charge the car on level 1 or 2 charger.
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.
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.
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.
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. 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 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.
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.
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.
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.
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 public chargers, it creates a safety and mobility risk, especially if the vehicle becomes stranded due to 12-volt system failure. I am concerned that this is a systemic defect in the ICCU that impacts vehicle reliability and safety and should be investigated further.
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.
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.
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.
My car (Kia EV6) suddenly stopped charging with Level 1 and Level 2 charging. I brought it to the Kia dealership and it was diagnosed ICCU failure. ICCU was swapped and the car is charging again.
The vehicle lost the ability to charge on Level 2 and Level 1 charging. I took it to the Kia dealer and they told me it was the ICCU, took then a week to repair.
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.
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.
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
ICCU failed. Level 2 charges didn’t work.
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
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.
