My car suffered an ICCU and high-voltage fuse failure despite having been previously inspected as part of Service Campaign 997, which found no reason to replace the parts. After 24,700 miles and 16 months of service, the parts failed. This was only 4 months after the service campaign was completed. Similar to others who have reported ICCU failures, I suffered a rapid loss of power on the road, and within minutes, a complete loss of motive power. I received a “check EV system” and “reduced power” warning, followed very quickly by “check power supply, pull over immediately.” While I was able to pull to the roadside, this easily may not have been the case, causing significant danger. The dealer confirmed the issue and eventually replaced the parts. A loss of motive power within minutes or seconds is potentially life-threatening. Hyundai’s proposed fix for the issue — inspection and perhaps software update — is clearly inadequate to address the problem, since my vehicle failed after the service campaign had already been performed.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the pedestrian warning system was inoperable while reversing. Additionally, the contact stated that the battery was 92 percent charged; however, while driving 30-40 MPH, the message "Electric Power Failure" was displayed. The contact turned off the heater and the radio and continued driving. The contact stated that while parking the vehicle, the message "Electric Power Failure - Stop Immediately" was displayed and several alarms sounded. The contact notified the dealer and was informed to drive the vehicle to the residence and the vehicle would be picked up. The contact stated that while driving to the residence, the failure recurred, and the vehicle failed to respond upon depressing the accelerator pedal while driving uphill. The contact became aware that the vehicle had lost electrical power. The contact was able to veer to the side of the road. The vehicle was towed to the dealer, where it was diagnosed that the integrated charging control unit (ICCU) needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 9,600.

The vehicle was being driven normally on city street and I heard a thump in the rear end of the vehicle. Very soon after, got a message on screen to check electrical charging system with the indicator lights for 12 volt battery and EV system illuminating. Parked the vehicle a kilometer after thump to deliver something to a friend (the car sat for 10 minutes). Resumed driving and then within a kilometer received a message that drive power would be limited -- significant decline in drive power... put my flashers on but did not stop because on busy street with no parking ... within two blocks, message of "stop vehicle and check power supply" appeared with full drive power ending within one block -- within that block, I was able to turn down a side street and coast down a hill to a parking lot. Attempting to turn vehicle off, the screen showed erratic behavior and headlights went on and off. Finally, was able to get everything off but was not able to lock the vehicle. If this drastic loss of power had occurred on a highway, there is a likelihood that such a power failure would have led to an accident.

The car started reporting error messages including "Stop vehicle and check power supply". It briefly went into limp mode before dying completely. Flat bed to dealer who can't begin diagnosis for at least a week. This sounds identical to the ICCU issue that many owners are experiencing.

My 12v battery died on 11/12 while my main battery still had 52% charge remaining. Had to jump the battery to get the electrical system to work. Since then several of the cars electrical systems are not working. This is a known issue online that Hyundai has responded to but the dealer is saying that they are not aware.

3PE24028 · Electrical Arcing And Thermal Events, Potentially Leading To Fires, While Utilizing Enel X Way Usa, Llc's Juicebox Residential Charger.
Opened Oct 3, 2024 · Closed Jun 5, 2025
Status: closed (inferred from source dates) · Equipment:electrical
On October 3, 2024, the Office of Defects Investigations (ODI) opened PE24028 to investigate alleged failures of Enel X Way's JuiceBox Level 2 residential EV chargers. The allegations were described as thermal incidents and electrical malfunctions, which could trip the circuit breakers in Juicebox owners’ homes and disrupt electric vehicle charge cycles. On October 2, 2024, Enel X Way posted on its website that Enel X Way North America would cease operations in the United States and Canada on October 11, 2024. The closure would potentially impact the charging app and supporting software. ODI sent Enel X Way an Information Request (IR) letter on October 21, 2024. Enel X Way provided an incomplete response to the IR on December 9, 2024. Enel X Way later provided a complete response to the IR on January 24, 2025. ODI reviewed Enel X Way’s IR submissions to determine whether further action is required. Based on ODI’s analysis, there was no clear trend in the cause of the failures described in customer complaints and warranty reports. Additionally, there have been no recent reports alleging safety issues. The available information does not warrant further action at this time. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor for any safety trends and reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in this Closing Resume, go to NHTSA.gov.
PE23011 · 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.
