Car lost charge quickly, went into limp mode while I was driving on the highway. I had to pull of the road several times and try to get it to a charging station. It barely made it after the lose of power. Charged it to 80% and it would only go up to a range of 100 miles. Took it to the dealership and they confirmed it needed a whole new main battery. ICCU had already been replaced. Had to wait over 5 months for replacement parts.
On Sunday, March 1, 2026, my vehicle suddenly malfunctioned while I was driving. The car abruptly lost power, would not accelerate beyond 25 miles per hour, and then completely shut down within minutes.

On Sunday, March 1, 2026, my vehicle suddenly malfunctioned while I was driving. The car abruptly lost power, would not accelerate beyond 25 miles per hour, and then completely shut down within minutes. This left me stranded on the roadside off the highway, which was both dangerous and extremely distressing. The vehicle was towed to the dealership, and it has now been four days with no updates regarding the diagnosis, repair plan, or estimated timeline. I have repeatedly attempted to get information but have received no meaningful communication. This situation is unacceptable for a relatively new vehicle and raises serious safety concerns. In addition, I rely on this vehicle daily and am currently without transportation.
Having the same ICCU Failure that all other Ioniq 5 owners have. On February 26th, I was heading to work when I heard a pop and car displayed warning lights saying check EV system and stop safely. Car was limped home and towed to dealer. Was told fix will take a month.
My car reported an error "check electric vehicle system" and would not drive over 25 mph. I had it towed to the nearest Hyundai dealership. This was after the car repeatedly killed the 12 volt battery. This is a common issue known with the ICCU.
The ICCU in my 2023 Ioniq 5 has failed for the second time. The 12V battery is dead and the car cannot be driven. It will be sitting at the dealership waiting for a new part for at least a month. Hyundai claims to have fixed the ICCU problem but from online reports it is clear that they have not solved this problem.
While stopped at a stop light, "check electrical system" warning flashed on instrument panel without any prior warning or malfunction. I was only able to move the car about 50 feet before all power and controls failed. I was in a middle lane and was barely able to move the car out of traffic. Tow truck driver with a large jump …

While stopped at a stop light, "check electrical system" warning flashed on instrument panel without any prior warning or malfunction. I was only able to move the car about 50 feet before all power and controls failed. I was in a middle lane and was barely able to move the car out of traffic. Tow truck driver with a large jump start battery pack was able to give it enough power for me to crawl it onto their flatbed, my small lithium jumpstart pack was only enough to get the rest of its doors unlocked. Battery temperature was about 30 degrees F, state of charge 75 percent, had been driving from home less than 10 minutes, car had been sitting outside for a few days. Problem diagnosed as ICCU failure by dealer service department, now waiting on replacement part to complete repair.
My 2023 Hyundai Ioniq 5 suffered a sudden Integrated Charging Control Unit (ICCU) failure that put me in grave danger. As I left my workplace in the evening, I heard a “pop” sound and got the dashboard warning, “Check Electrical Vehicle System.” It was unclear what the warning meant. I had 65% charge left at that point. As I be…

My 2023 Hyundai Ioniq 5 suffered a sudden Integrated Charging Control Unit (ICCU) failure that put me in grave danger. As I left my workplace in the evening, I heard a “pop” sound and got the dashboard warning, “Check Electrical Vehicle System.” It was unclear what the warning meant. I had 65% charge left at that point. As I began driving, the gas pedal “stuck,” not allowing me to accelerate past 25 mph, and it felt like the car was dragging. I did not know what was happening. The “Check Electrical Vehicle System” warning returned but gave no indication of whether it was safe to drive or what to check in the electrical system. Driving very slowly, I made it out of the military base (my workplace), parked outside of a closed establishment, and called my husband. He told me to drive further up the road to a well-lit shopping area. I exited the parking lot and entered the intersection of a four-lane highway – and suddenly, when I was in the center about to turn in the direction of traffic, the car stopped and would not respond to the gas pedal. I could not accelerate and was stuck in the middle of the highway. After several frantic pushes on the gas pedal, I was able to coast downward to the shoulder and exit the vehicle. My husband and I had brought the car to the dealer in February 2025 for the December 20, 2024 ICCU recall (NHTSA Recall 24V-868, Hyundai Recall 272). The dealer merely inspected the car and updated its ICCU software. Per Hyundai guidance, it did not replace the ICCU itself. It is taking no apparent steps to do so for 2023 Ioniq 5 owners, leaving us in danger. The seriousness of this problem is compounded by the lack of adequate warning when it occurs out of the blue. The generic “Check Electrical Vehicle System” indicator on the dashboard did not indicate what precisely in the electrical system to check, how serious the issue was, or how much of the 12-volt battery power was left. Hyundai must rectify this issue before others are hurt.
ICCU failed while driving, car limited speed immediately. This was after software recall was preformed a few months prior. Car went limp mode and repairs are going to take an indefinite time.

I purchesed the Hyundai ionic 5 2023 from hyandai dealer ship. It had 42 k miles. The car ran good. So I got it. They promised me before the I bought they would charge it up free. When I signed the paper they said they couldn't charge it for me. I drove 5 miles the original battery died. I almost got to accudent only 5 miles away. I figured it was original battery. I change battery. I get tow truck to take home i put new battery in it. Then 5 days later the main iccu stopped charging. Another 12 bolt battery drain. They new it had that problem. Two batteries are main iccu won't charge. They make me sign paper buy as is i didnt think it would die 5 miles later they new it had a serious problem I look on internet the same car had recalls for the same car not on mine My car should have been recalled I heard 1000 s were affected with the same problem. They new it would fail on me thars why they get me to sign the papers. I hooe it's not 21 k down the drain I hope i dont have to spend 15 k on new iccu.

1PE23011 · Loss Of Motive Power
Opened Jun 8, 2023 · Closed Apr 17, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery; Electrical System:propulsion System:dc/dc Converter
On June 8, 2023, the Office of Defect Investigation (ODI) opened PE23011 to investigate allegations of loss of motor power on model year (MY) 2022 Hyundai Ioniq 5 vehicles. Some consumers reported loss of motor power immediately after a warning lamp illumination or reduction of motive power while the vehicle was in motion. This investigation found that the Integrated Charging Control Unit (ICCU) may be subject to various conditions such as overcurrent, overvoltage induced at the end of charging, and certain thermal loading during operation that can damage its internal components and open the ICCU fuse, resulting in an inability to charge the 12-volt battery. The vehicle could eventually lose all motive power, increasing the risk of a crash. In July 2023, Hyundai issued a service campaign to address certain MY 2022-2023 Ioniq 5 and MY 2023 Ioniq 6 vehicles that may have low 12V auxiliary battery charging occurrences due to an ICCU fault and may set the DTC P1A9096 “DC/DC Converter Input Voltage Sensor Fault”. On March 15, 2024, Hyundai filed Safety Recall 24V-204 for 98,878 MY 2022-2024 Hyundai Ioniq 5 vehicles and MY 2023-2024 Hyundai Ioniq 6, Genesis GV60, Genesis GV70 “Electrified” and Genesis G80 “Electrified” vehicles. The recall remedy provides an inspection, and if necessary, a replacement of the ICCU and the associated fuse. The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging. The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving. In view of the recall action being taken by Hyundai, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
