Vehicle failed to start and a jump is required to start the vehicle for the first time on 10/6/2026. This has now happened numerous times and at times when the vehicle's power train batteries are charged. An small portable charging device has been purchased to jump the vehicle which eliminates the need to call for roadside assistance. Roadside assistance has take over 2 hour to response. An error on the dash indicated the 12 Volt battery has lost charge. There is a red circle message displayed on the dash. The vehicle was taken to Batteries Plus and a battery and alternator test. No problems were noted. The vehicle is scheduled for a dealer inspection on 10/22/2026.

I was driving in heavy rain on a busy highway (I4) and the lane assist pulled me off the road to the road hand side and then cut across all lanes of traffic to the left hand side. It also engaged emergency braking going forward when there was no reason to do so. Many times when I am backing up, it's engaged emergency breaking when there is no risk of collision. Finally, the front sensors are very inconsistent with when they go off. Today I was not moving and neither was the car ahead of me, first it told me I was too close (yellow) on the left bumper, then it turned off and told me I was too close (red) on the front, turned off again and went back to yellow on the right and then turned off again.

ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an “check electrical” warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.

I charged my car at a level 3 fast charger on a road trip. After completing my charge, the AC stopped working. The fan worked but it was only blowing hot air. Normally this would be a nuisance, but the day was about 114 degrees and the car’s interior was probably close to 140 degrees. I was driving on the interstate so it was very hard to keep the windows down. The lack of HVAC made the car difficult to operate and if my family was in there would have been a safety hazard. I took it to the dealer who initially thought it need the coolant to be recharged. It turns out that the inverter for the A/C died. Apparently this has some connection to the known issues with the ICCU, which in my case just blew out and was replaced a month and a half prior to this incident.

While driving southbound on the [XXX] in a rented 2023 Kia EV6 from The Hertz Corporation, picked up in [XXX] on XXX, the vehicle entered "Power Limited" mode without warning. The vehicle lost normal propulsion and decelerated from highway speed to a crawl, forcing 4-5 emergency stops onto the highway shoulder over several miles while semi-trucks passed at 70+ mph in live traffic, with two minor children in the vehicle. The vehicle was ultimately abandoned at a highway rest stop on Hertz Roadside Assistance's instruction and towed. This vehicle was subject to three NHTSA recall campaigns for the ICCU defect that produces exactly this failure mode: 24V057000 (SC295, driveshaft, notice mailed XXX), 24V200000 (SC302, ICCU 12V charging failure/Power Limited mode, notice mailed XXX), and 24V867000 (SC327, expanded ICCU remedy superseding SC302, notice mailed XXX) — all mailed well before this vehicle was rented to me on XXX. Under 49 U.S.C. §30120(i), a rental company may not rent a covered rental vehicle subject to an unremedied safety recall. I am requesting NHTSA use its inspection authority under 49 U.S.C. §30166 to determine whether Hertz completed the required SC327 remedy on this vehicle before renting it to me, and to review Hertz's fleet-wide recall compliance for its Kia EV6 inventory.

First ICCU the power completely went out on 2/23/26. Power went out again April, 2026. Currently car is immobile and unreliable and not safe for driving due to power failures. Towed car to Kia Cerritos. Car supposedly "fixed" (with other issues I've reported to KIA of America & CA BAR/DMV) Currently 12V battery is not holding charge as of 4/27/26, 4/28/26, and 5/2/26. I received a letter from KIA stating ICCU and inability to charge, Keep this Letter in your Glove Box for a free diagnosis and possible no cost servicing. As an older American this is inherently unsafe, as I travel for work and cannot be stuck on the road. The vehicle suddenly loses power in traffic. It simply stops running. This is my 5th attempt to file this very complaint between April and 6/14/26.

The ICCU unit failed. The message "Check Electrical System" appeared on the instrument cluster. Low-voltage battery voltage was 12.0V and vehicle speed was limited to 60 mph. Maximum speed was gradually reduced to 30 mph over a period of 40 minutes (voltage was 11.5 V) with minimal 12V loads. I pulled over and called a tow truck to the nearest service center. Kia confirmed the ICCU was defective and replaced the part under warranty.

ICCU failed despite all prior recall updates being performed. Incident began when home circuit breaker tripped; vehicle subsequently refused Level 1 charging with "Check Electrical System" warning. Per dealer suggestion, tested public chargers. Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown. Vehicle then displayed "Stop vehicle and check power supply," and was unable to drive above 40mph (with a turtle icon visible on the dash) once I pulled away from the charging station. This created a significant safety hazard while navigating traffic. Within two hours, the 12V battery was completely depleted; vehicle was unresponsive and required a jump-start for towing. Dealer confirmed ICCU failure requiring replacement. The fact that the vehicle's internal failure caused the immediate malfunction of public infrastructure is deeply concerning, as was the loss of motive power on the road.

My vehicle has been in the possession of Koons Kia of Owings Mills since March 15, 2026, for diagnosis and repair of this issue, with service beginning March 16, 2026. During this time, the dealership has replaced the 12-volt battery and performed a software update; however, the defect has not been corrected. On April 10, 2026, I was notified that the vehicle was ready for pickup. When I arrived on April 11, I found that the battery was completely discharged and the issue had not been resolved. Because the vehicle was not operational at the time of attempted pickup, it was not returned to me and remained in the dealership’s possession. I was contacted again on April 13, 2026, and informed that the vehicle had been repaired. When I returned to the dealership on April 14 to retrieve the vehicle, I again found that the battery was discharged and the defect persisted. As a result, the vehicle was not returned to me and has remained continuously in the dealership’s possession since March 15, 2026. As of today, the vehicle has been out of service for more than 30 consecutive days due to this defect, and multiple repair efforts have failed to resolve the issue. This ongoing condition substantially impairs the use, value, and reliability of the vehicle.

I was driving 40mph and received a yellow error message along the lines of "electrical system issue, please check" and my speed was limited to 25mph. After trying to get the car to a safe location (as I was on a narrow two-lane road), the error changed to a blinking red error and my speed was further limited to 12mph. I was unable to get the car one mile to the dealer for service, so I stopped the car in a parking lot and had it towed to the dealer.

In November 2025, after charging car overnight, backed out of driveway and began to drive. Within 100 feet, received red error message and tone: “Stop vehicle and check power supply”. Stopped the vehicle and got it towed to Kia dealer, who confirmed that the ICCU had failed, despite the car having received the software patch purporting to fix the problem. The ICCU was replaced under warranty within a week. We were fortunate that this occured very close to home, without safety consequences. Ten minutes later, the car would have been travelling at 65 on a highway with no shoulder for long stretches, which would have been very dangerous. This was a certified preowned EV6 with less than 9000 miles on it. The 12 volt battery was brand new, having been replaced 3 months earlier with an AGM battery as a possible preventative measure for this issue.

The component that is seeming to fail in most KIA EV6's is the ICCU assembly. This is the component that failed in my KIA EV6 GT. Part# 364-1XFA0AQQK Also the ICCU Fuse, Part#375F2-GI040QQK FUSE-HIGH VOLTAGE. My safety and everyone around me was put at risk when the vehicle loss power due to this ICCU failure. As I entered the highway the vehicle starts loosing power. The vehicle gradually lost power more and more over time. I was able to make it to an exit driving at approximately 20-30 mph, and was able to drive it back to my house where it was then towed to a dealership. The problem has been confirmed by the dealer. I have the invoice to prove the repair of the ICCU. Yes there were warning messages on the screen when the ICCU failed. First, there was an audible "POP" which was the fuse blowing first. Once the fuse blows, it slowly kills the 12v battery and the car then looses power and you're no longer able to drive the vehicle. At that point, the ICCU is blown. The error message showing on the screen was: "CHECK ELECTRIC VEHICLE SYSTEM". Then the display starts blinking red and displays "STOP VEHICLE AND CHECK POWER SUPPLY". I have all the screenshots of the error messages the vehicle displays. The text message that is attached to this complaint is the service tech informing me that the 12v battery that they charged me $366.66 for, DID NOT FIX THE ISSUE.

While charging my vehicle at a level 2 charging station, my vehicle ceased charging. I received no other warnings or symptoms prior to my vehicle ceasing to charge. Upon being alerted by the Kia Access app that the charging stopped, I went to check my vehicle and none of my doors would unlock in response to the buttons on my keys. I had to manually unlock my driver side door in order to enter my vehicle. I attempted to start my vehicle and unplug/re-plug in the charger, but my vehicle would not start or charge. Using a portable jump starter, I was able to jump start my vehicle and begin charging again. However, after approximately 5 minutes of charging, my vehicle stopped charging and once again would not start. At that point, I called for my vehicle to be towed to a Kia Service Center. The Kia Service Center was able to reproduce the problem of my vehicle not starting or charging and informed me that there was an internal short circuit caused by a bad Integrated Charging Control Unit (ICCU). The bad ICCU shorted my ICCU fuse, resulting in the draining of my 12-volt battery. The ICCU and fuse were replaced at no cost to me. Although my vehicle is available for inspection upon request, the parts that malfunctioned have been replaced with new, functioning parts. My safety or the safety of others were not at risk in this situation, but I was fortunate that my 12-volt battery died while parked and charging, not while I was driving, which could have caused an accident.

While the vehicle was on the charger, the ICCU failed which then caused then fried my JuiceBox EV40 charger and flipped the dedicated circuit breaker. The car has since been repaired. I am concerned that this is a dangerous failure. If it happened on the road it potentially left me without propulsion. I'm also concerned that but for the circuit breaker functioning as designed it could have caused an electrical fire. My understanding is that this has been an ongoing problem with Kia and Hyundai EVs. I do not believe that Kia/Hyundai are taking responsibility for fixing the problem that have not plagued other manufacturers.

While driving in the evening with an estimated 180 miles range remaining a "pop" noise was heard. About a minute later a vague warning message the car had not displayed before appeared. We tried to make it home but concerning (and still vague) messages kept appearing quite rapidly. The car slowed down and came to a halt and died in an intersection. This all happened within five minutes of hearing the "pop" noise. Once the vehicle died the head and taillights went off and the car would not allow the emergency flasher lights to be turned on. It would not allow it to be put into neutral to allow it to be moved out of the intersection. It also would not allow any of its doors to be locked (manually or otherwise) except for the driver's door until the vehicle was repaired one week later. We found out following that the 12 volt battery had not charged due to a DC/DC converter input voltage sensor fault related to ICCU failure. The popping noise had been a fuse. As the applicable ICCU parts were replaced by the dealership I doubt they will be available for inspection. The safety of my family was put at risk by: - the car's warnings not clearly explaining what the issue was. - the car not giving clear indication of how quickly it would die. - the car dying in a busy intersection. - the car being unable to be shifted to neutral. - the car's warning flashers not being operational when it died in the middle of the intersection at night. - us being left without warmth in outside temperat

There were no warning lights, sounds, or messages displayed on the car's gauge cluster display, either for the initial loss of propulsion or for the restoration of propulsion. This caused a loss of traction when the car eventually passed through a patch of packed snow and ice.

While driving my Kia EV6 in the middle of a snowstorm, the vehicle experienced a sudden and severe power failure. I heard a loud popping sound from the rear of the cabin, after which the vehicle immediately entered reduced-power (limp) mode. Within approximately one minute, the vehicle shut down entirely and lost all propulsion and mobility. I was able to move the vehicle to a safe location only because I was not in traffic or on the highway at the time of the failure. Had this occurred at highway speeds or in active traffic, it would likely have resulted in a dangerous situation with a high risk of collision, especially given the severe winter weather, low visibility, and slippery road conditions. The vehicle has approximately 21,000 miles. This is the second failure of the Integrated Charging Control Unit (ICCU) in this vehicle. The vehicle was inspected by an authorized Kia dealer, who has officially diagnosed the failure as a failed ICCU and associated fuse. There were no warning lights or messages prior to the failure. The first indication of a problem was the popping sound, immediately followed by limp mode and then a complete shutdown without further warning. The vehicle is available for inspection upon request. The repeat nature of this failure, lack of advance warning, and sudden loss of propulsion represent a serious safety defect.

ICCU failure. Was confirmed by shop car was towed to over phone. But no mention of it on invoice as of yet. I was at traffic light when I heard a pop and when I tried to go, got the warning message to pullover and the turtle icon. I made it to a towable spot. Super fortunate all in all. Can’t imagine if on highway in weather. No hints of failure before. Car was recently purchased month prior. I took it in for recall within first week, was told all good, software was updated. I kept between 20%-80% at all times, charged lvl2 at work daily and lvl1 at home sometimes. Had cheap voltage meter in car and was reading fine. Hope to get my car back soon.

It seems as if the ICCU on my car failed. It will not charge and went into limp mode in order for me to drive it home a few blocks.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
