On January 1st 2026 around 11am we were traveling in rural Wisconsin when we heard a loud pop from under the back seat . This we now know from Dahl Hyundai in LaCrosse was the ICCU failing . When this happened we were in blizzard conditions and the car forced us into limp mode and reduced us from 55 mph down to 25mph in bumper to bumper traffic on a rural hwy (this was not a smooth speed transition the car performed ) We drove the vehicle back to the nearest town going 25mph as it was alerting us that we were on limited battery as this issue in short time will make the vehicle inoperable . We found a safe place to stop and did so. We called Hyundai Roadside assistance who then let us know it would be 9 minutes until we received help. This would actually take 4 more hours . They left us with a car that did not operate , produce heat in a blizzard . We eventually had family pick us up so we were safe . We still do not have the vehicle back as Hyundai America has the part (ICCU) on back order with no ETA of repair. .

Multiple 12v batteries, the battery management system, and ICCU have all failed on my Ioniq 5. During my 13-month lease, this vehicle has been inoperable for more than 30 cumulative days due to the same recurring defect. The vehicle was taken to an authorized Hyundai dealership multiple times, but the defect was repeatedly misdiagnosed and not corrected, resulting in continued failures and extended loss of use. The defect causes sudden loss of power and complete vehicle shutdown, including the inability to restart the vehicle. If this occurs while driving, it creates a serious safety hazard by eliminating propulsion, power-assisted steering, and braking assistance. The vehicle may become disabled in traffic or at intersections, increasing the risk of a collision, injury, or stranding occupants in unsafe conditions.
The vehicle was returned to me after a manufacturer-authorized high-voltage battery replacement that was completed on December 10, 2025.

The vehicle was returned to me after a manufacturer-authorized high-voltage battery replacement that was completed on December 10, 2025. Immediately after pickup, the vehicle began exhibiting safety-related issues. I experienced abnormal and hard steering operation, repeated low coolant warnings, and battery management system (BMS) and electrical warning messages. These warning messages appeared immediately after the repair and before the vehicle was driven by me. I returned the vehicle to the dealership multiple times for the same issues. During the final visit, the dealership retained the vehicle for approximately 12 days. After this inspection period, I was informed that the vehicle had underbody damage affecting the coolant system and high-voltage battery and that the damage was likely caused by road debris. The issues began immediately after the battery replacement and involved safety-related systems including steering, coolant, and the high-voltage battery. The vehicle was returned with unresolved warning messages related to these systems. I am concerned that the vehicle was released after a major battery repair in an unsafe condition and that the affected systems may not have been properly inspected or repaired prior to release.
On the morning of [XXX] I received an error message on my dashboard (attached) "Stop Vehicle and Check Power Supply". The car had started to lose acceleration power to no more than 30MPH.

On the morning of [XXX] I received an error message on my dashboard (attached) "Stop Vehicle and Check Power Supply". The car had started to lose acceleration power to no more than 30MPH. I contact the service department at my local dealer. They instructed me to bring it in or have it towed. I was about 2 miles from home so I headed back. While in transit the car lost all power in the middle of traffic. It stopped completely ! No emergency flashers, lights, power for the doors, windows, etc. I could not even put into Park. If I lifted my foot off of brake, it started to roll backwards. Luckily I was not on the expressway or at a railroad crossing. Fortunately a local police officer saw my dilemma and directed traffic and pushed my car to the side of the road ([XXX]) After doing research online I found this to be a common issue with Hyundai/Kia EV vehicles. The ICCU fails with no warning leaving drivers stranded..

12 volt battery drained in my driveway on 1/20. Vehicle was completely dead including door and hatch locks. Roadside assistance jumped the 12 volt battery. Vehicle message said, “Insufficient power. Check Electrical system”. Vehicle was towed to local Hyundai dealer, who diagnosed an ICCU failure. The dealer has four other Ioniq 5s with the same problem. Replacement ICCU is on back order with no ETA for delivery. There were no warnings prior to the ICCU failure. If the vehicle were being driven when this failure occurred, the loss of power would have put all occupants at great risk.
The ICCU failed at 11,000 miles and 11 months into the lease. When the ICCU fails, the car becomes inoperable. This was a major safety hazard since it broke down on a major US highway and I was barely able to get off to the side of the road. This seems to be affecting a large number of Ioniq 5 and Ioniq 6 models.
What component or system failed or malfunctioned, and is it available for inspection upon request? - It was ultimately diagnosed as an ICCU failure. The part is no longer in my possession. How was your safety or the safety of others put at risk? - Occurred on public street, fortunately a slow moving 25MPH speed limit several blo…

What component or system failed or malfunctioned, and is it available for inspection upon request? - It was ultimately diagnosed as an ICCU failure. The part is no longer in my possession. How was your safety or the safety of others put at risk? - Occurred on public street, fortunately a slow moving 25MPH speed limit several blocks from my workplace. I was able to limp the vehicle to a nearby parking lot and call for towing. Unfortunately, several hours later the vehicle was unable to be moved, leaving me stranded, and requiring it to be towed to local Hyundai dealership. I was ultimately without a vehicle for >1 week. Has the problem been reproduced or confirmed by a dealer or independent service center? - Yes, confirmed as ICCU failure. Additionally, my vehicle had the software update at the time that was supposed to fix / greatly decrease the rate of ICCU failures. I had no outstanding recalls on the vehicle. Vehicle was ~1 year old and had less than 12,000 miles on it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - Yes, at least local Hyundai dealership mechanics Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - Initially the error message "stop vehicle and check power supply". The next day, that message, then a yellow turtle and "Power Limited"
While driving, I heard a loud pop in the rear passenger side and subsequently, the dashboard showed an error to "stop vehicle and check power supply". After driving about 15 minutes, another error showed on the dashboard "12V battery voltage low. Stop safely". After coming to a stop, the vehicle completely shut off and would not…

While driving, I heard a loud pop in the rear passenger side and subsequently, the dashboard showed an error to "stop vehicle and check power supply". After driving about 15 minutes, another error showed on the dashboard "12V battery voltage low. Stop safely". After coming to a stop, the vehicle completely shut off and would not turn back on. A tow truck was called and my vehicle was towed to a Hyundai dealership. The vehicle is now at the service center at a Hyundai dealership. The dealership confirmed it was an ICCU failure. While there was not a crash or any injury, the known defect from Hyundai left my wife, my [XXX] daughter, and me, stranded 60 miles away from home, in the middle of the night. Luckily we were pulled over safely and not in the middle of the highway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
