IllustrationICCU failure, confirmed by dealer. Vehicle was parked in garage connected to charger. The ICCU fuse blew, and the house breaker was tripped. The vehicle failure also ruined the Grizzl-E EVSE (charger).

ICCU Failure — Severe Safety Risk and Repeated Incident The ICCU in my Hyundai has failed twice. Both times, the car suddenly and completely lost power while I was driving — no warning lights, no gradual slowdown, just total loss of control. This created an extremely dangerous situation that put me, my passengers, and everyone around us at risk. When the ICCU fails, the vehicle shuts down instantly and becomes completely inoperable. During the most recent incident, I spent more than eight hours on the phone with Hyundai attempting to arrange a tow. When the tow truck finally arrived, the driver instructed me to shift the car into neutral. The moment I did, the car died again and became stuck in neutral, preventing the driver from towing it. He then left, unable to assist, leaving my disabled vehicle parked on a public road — on a hill — where it posed a further safety hazard. Hyundai’s response to these failures has been temporary at best. This issue continues to reoccur, making the vehicle effectively unsafe to drive at all times.

The car stopped trickle charging even though it wasn't at 100%. When I turned it on, there was a warning message indicating an electrical failure. I called the dealership and they said it was unsafe to drive it the 2-3 miles to the dealership so it had to be towed. Once it was diagnosed, the dealership told me the ICCU had failed. This is a known defect in this car that for some reason has not been resolved with the previous recalls, and the replacement units that are installed are just as prone to failure as the original. It is expected that I will have the car back approximately one week after it was towed to the dealership.

The ICCU, which is an electrical component that charges the 12 volt battery, failed. As a result the power drained completely and the car shut down. This is a safety issue because it happened while driving and my husband just barely had time to get the car over to the side of the road. It has also been know to happen to cars of this model while driving on a highway, which is obviously very dangerous. The problem has been confirmed by a dealer - Gary Rome Hyundai in Holyoke MA. They ordered us a new ICCU, which took about a month to get. Orders for the ICCU's are backed up because this problem has been happening to so many cars. And as the dealer reported, the problem has been known to happen to the same car multiple times, even after the ICCU is replaced. The vehicle was not inspected by the manufacturer, police, or insurance. It was towed to the dealership for repair. There were no warning messages until the battery started failing and it was only about a minute before the car shut down.

Picture of a turtle shows up. Low power warning. Car lost power within 10 seconds. And couldn't accelerate. Extremely dangerous. …

Had all previous open recalls for iccu performed. No previous warning in car. Driving unto free way. Loud noise like a tire pop. 12 volt low power warning on dash screen. Car began to lose power. Picture of a turtle shows up. Low power warning. Car lost power within 10 seconds. And couldn't accelerate. Extremely dangerous. Once completely stopped the car turned off and couldn't start again. Was able to get car to turn on with jumper cables by tow truck. But couldn't get to "start" engine. Dealership says the 12 volt battery and iccu needs to be replaced. They are blaming the issue on the fact that I had an aftermarket subwoofer installed and don't want to cover under warranty. Car ran fine with said subwoofer for a year prior with no additional changes. Have used same subwoofer and amp on multiple cars with no issue.
The car would not start when start button was pressed. Warning on the dash said 12v battery critically low. This happened on three different occasions. After jump starting the car, everything works as normal. I am able to turn off and turn on again as expected. 12v battery was tested and seems to be fine. Even the OBD2 reading…

The car would not start when start button was pressed. Warning on the dash said 12v battery critically low. This happened on three different occasions. After jump starting the car, everything works as normal. I am able to turn off and turn on again as expected. 12v battery was tested and seems to be fine. Even the OBD2 readings show battery as working correctly. There seems to be a software glitch that makes the car think that the 12v battery is low. The high voltage battery was charged to above 70 at least on all three occasions. Now I carry a external jumper battery to avoid this situation

The Integrated Charge Control Unit failed despite having all related recall repairs/actions implemented. Failure occurred while pulling into a parking place after completing level 2 charging to 80%. The failure has not yet been confirmed by the dealer, but all common symptoms match this failure including hearing a pop sound from the rear of the vehicle followed by “Check Electrical System” indication and limited distance low power, low speed mode. Had this happened while driving at highway speed, the sudden loss in power and speed could have been dangerous to respond to and get off the highway safely. The vehicle is scheduled to be inspected by the dealer shortly.

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.
