I was driving on a highway during traffic on June 17 2025 and my ioniq 5 car started to make weird sound. Then after a minute, it abruptly started to push back and forth and the noise became stronger. A couple of minutes later, the "Check electrical vehicle system" sign was displayed on the screen. I pulled over due to the scare and turned off the car. A minute later, turned ON the car and drove. Same exact thing happened a day before too. This has not happened before since I got the car in Dec 2024. Car's battery was at 82%.

Vehicle lost power on a two lane highway with a 55mph speed limit, which increased the risk of an accident. Warning lights appeared after the failure occurred; essentially giving the driver little to no warning. The vehicle kept slowing down to 30-25 mph, but fortunately close enough to home and was able to slowly roll into the garage. The vehicle was towed to the dealership and will take 2 months for the ICCU and ICCU fuse to be replaced due to backordered parts. This occurred after an ICCU update was done in 12/24.

ICCU (Intergrated Charging Control Unit) failed after two mandatory recalls were completed. Vehicle is not drivable as it’s awaiting for a replacement ICCU (backordered). Replacement ICCU will not remedy the issue since it has not been improved upon from the original failure. Vehicle shutdown on a two lane highway with a 65mph speed limit. The section where the vehicle shutdown was without cellular service and on a bend with no shoulder, which increased the risk of an accident. The problem was reproduced in other vehicles using the same part. The component has been inspected by the manufacturer and dealer with a temporary remedy of replacement. Warning lights appeared after the failure occurred; essentially giving the driver no warning or time to react. The vehicle displayed a warning message to pull over and turn off vehicle immediately. Power was reduced to 15mph for about 15-20 minutes.

On Monday May 12, 2025, while driving my Ioniq5 (2024) several warnings appeared concerning the EV electrical system. One warning dealt with 12 volt battery issue and other warning alerted the entire vehicle's electrical system was failing with instruction to stop driving vehicle immediately. I was out of town and my car was towed to local hyundai dealership. The problem appears to be a faulty ICCU component and parts have been ordered. Having my brand new EV turn off in traffic is scary and this experience has been frustrating and nerve wrecking. Knowing Hyundai was aware of this problem makes it even worse.

-The Integrated Charging Control Unit (ICCU) component failed. The vehicle experienced multiple electrical system warnings before losing functionality. The component should be available for inspection upon request. -The vehicle lost power while I was driving. The "Stop Vehicle" alert appeared, requiring me to immediately find a safe location. Had this happened in high-speed traffic or an unsafe environment, it could have led to an accident or left me stranded in a hazardous situation. -the problem has been confirmed by a dealer. The vehicle has been inspected by the dealership following the issue, but it has not been examined by other entities such as police or insurance representatives. -Yes, the “Check Electrical System” warning appeared twice briefly before disappearing weeks/months prior. However, no immediate issues followed those warnings at the time. The day of the failure, the "Check Electrical System" alert appeared again, followed by a "Stop Vehicle" warning a minute later. After pulling over safely, a "12V Battery Depletion" alarm also appeared.

Have gotten all recalls fixed associated with the ICCU; car has less than 15000 miles on it and suddenly lost power, “check electrical system” and “power limited” lights flashing. We had no warning prior, and had just arrived back 2 days before from a long road trip. While I’m glad it happened while close to home, we still had to have our vehicle towed to the dealership and it took 3 business days to diagnose the issue (ICCU failure). We were put at risk due to the sudden change of status and inability to access the contents of our car after the power died (including my toddlers car seat).

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.
