IllustrationThe ICCU failed after completing all required recalls. The car stopped working while driving. The car losing power while driving could have created an accident had I not pulled over in time. The part was replaced by Hyundai under warranty and is now fixed.

The vehicle is a Hyundai Ioniq 5 electric vehicle. There have been known issues with the integrated charging control unit (ICCU) failing suddenly rendering the car inoperative; I just took it to the dealer and they confirmed a fault with the ICCU. I am up to date with multiple prior ICCU recalls and updates. Leading up to this, a few months ago my 12V battery died unexpectedly at ~22000 miles and I had it replaced. The ICCU charges the 12v battery so I wondered if there was an ICCU issue but the car otherwise was operating fine. Overnight while charging with a level 1 charger at home recently, the car stopped charging overnight unexpectedly. A couple days later I plugged in to charge at home again and got a message "charging unsuccessful", and on the dash I received a message that said "check electrical vehicle system" which went away when I unplugged the car. I tried a different level 1 charger from my wife's car and received the same "charging unsuccessful" message. Interestingly that charger no longer seems to work on her car, so it's possible that my car damaged the charging unit. I then went to try a level 2 charger maintained by the city of Seattle which was operative and had power when I plugged in. On plugging in, I received the same "charging unsuccessful" message and then the light on the level 2 charger went off and the level 2 charing unit lost power. Again, it appears that the fault on my car may have damaged an external charging unit. Thankfully I was still able to drive the car to the dealer where the ICCU failure was confirmed and am in the process of replacing it (they don't have the parts in house and told me the current wait is less than a week though previously had been sometimes months). A service rep told me many customers had the failure happen suddenly with a loud "pop" while the car was in motion causing them to limp to the side of the road or leaving them stranded.
My ICCU failed and left my family and I stranded. I understand that this is happening on many Ioniq 5s and that Hyundai has not come up with a reliable solution for this problem.

My 2023 Hyundai Ioniq 5 suddenly malfunctioned on Sunday, March 1, 2026. The vehicle abruptly lost power, would not accelerate beyond 25 miles per hour, and then completely died within minutes. This left me stranded on the roadside off the highway, and the car had to be towed to the dealership. It has now been over 10 days, and I have not received any updates regarding the repair timeline, or next steps. This situation is extremely frustrating, as I depend on this vehicle daily. I would greatly appreciate immediate communication regarding the status of my vehicle, including: •Expected repair timeline •What is Hyundai doing to alleviate this massive problem with ICCU? This Hyundai ICCU issue has been around for a few years now, but Hyundai has not provided a lasting fix. Leaving the IONIQ owner to suffer financial and emotional loss. Please get in touch with me as soon as possible with an update, I look forward to NHTSA's prompt response and a resolution to this issue. Sincerely, Dr [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I started the car and put down all 4 windows simultaneously. I heard a pop and a dash warning "Check electrical system". I knew this is symptomatic of an ICCU failure and the car will not be driveable for very far. This happened despite having recall work performed for this specific issue in September. That recall work was just a software update, but it is a hardware problem. Hyundai needs to fix the hardware problem. If this had happened when I was at a remote trailhead without cell service I likely would have been stranded. Fortunately I was able to drive 1-2 miles home and get the car towed. I was without a car for 4 days until Hyundai could get me a loaner vehicle. Unknown how long repair will take. Unknown what reliability will be after repair, if they just replace the ICCU with another that has the same potential fault.
I received a "Stop vehicle and check power supply" alarm on my dash after starting the car and leaving a parking garage. Then a "12V battery voltage low" message along with the "turtle mode" icon which limits the car to under 20 mph. I pulled over to a side street as I did not want the car to die on a main road and impede traffi…

I received a "Stop vehicle and check power supply" alarm on my dash after starting the car and leaving a parking garage. Then a "12V battery voltage low" message along with the "turtle mode" icon which limits the car to under 20 mph. I pulled over to a side street as I did not want the car to die on a main road and impede traffic or get hit. I called roadside assistance and the car was towed to the dealership.(1/16/2026). On Tuesday (1/19/2026) I was informed that the ICCU (Integrated Charging Control Unit) had failed. The dealership ordered the part(s) to be replaced and stated 5-7 days turnaround. Called dealership every 10 days or so, but was told there was no ETA for the parts delivery. On Thursday 3/6/2026 (48 days) received a text that the car was ready to be picked up. The ICCU and associated fuse was replaced.
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.

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.
