My 2022 Ioniq5 left me stranded late at night in a freezing rainstorm in March of 2024 when I was 75 miles from home at it failed to charge both D/C fast charging and A/C level 2 charging, despite my trying several different chargers. The car gave me the dreaded "Check E/V System" warning when it failed to charge. It turned out to be the notorious ICCU but also the AC inverter, which had to be replaced. It took 12 days. The dealership's initial diagnosis was something draining the 12-volt battery, so I asked if they also replaced that. They said no because it had tested fine, but 9 days after I picked up the car, it did not start because it turned out the 12-volt battery was dead, and my dealership spent 2 days getting Hyundai to approve replacement of the 12-vold under warranty. Last month, 17 January 2026, my Ioniq5 again left me stranded. This time 120 miles from home in a snowstorm. It D/C charged for 10 minutes before the charging stopped and it gave me the dreaded “Check E/V System” warning. I tried two nearby Tesla Superchargers with my Hyundai issued adapter, and they both failed. I had just enough charge to make it to a dealership 110 miles from my home, where the vehicle stayed for nearly a month while they diagnosed and repaired it by replacing the AC inverter (note that had been replaced the last time) and also the AC compressor. The ICCU failures are well-known and well-documented, but the AC inverters that failed on me twice do not seem to be as common and should probably be investigated. In both cases I was stranded on Saturdays when no dealership service departments were open until the following Monday, so I had to pay for a motel overnight, which Hyundai refused to reimburse because I was not at least 150 miles from home.

Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: ICCU failed - Not available for inspection (at least at this time, but willing to try and make it work). Q: How was your safety or the safety of others put at risk? A: The ICCU (Integrated Charging Control Unit) is a safety-critical component subject to federal recalls 24V-204 and 24V-868. (My vehicle had all recalls performed prior to this failure.) The failure occurred while driving which was indicated by a “popping” sound. It is contextually important to note that the ICCU is responsible for charging the 12v battery, had the 12v battery failed during the duration of my drive I would have experienced a sudden loss of motive power. A sudden loss of motive power is an unacceptable risk to public safety. Q: Has the problem been reproduced or confirmed by a dealer or independent service center? A: Yes, the problem has been reproduced and confirmed to be an ICCU failure by an official Hyundai service center. Q: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A: No. Q: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A: Symptoms first appeared February 14, 2026. The first symptom of failure was the signature “pop” sound that the ICCU failure is known for. Only after my drive and upon attempting L1/L2 charging did my dash warning indicate “Check Electric Vehicle System.” I also checked for codes with my OBDII scanner, and it showed no codes.

The Dealer states my ICCU has failed and will be replaced. My vehicle could no longer charge on AC power (level 1 or level 2), and eventually had to be taken to the dealer because it could not be charged at home any longer due to the ICCU failing.

While making the short drive to work on surface streets I was given a warning in an amber circle to check the electrical system. Moments later I was presented with a warning in a red circle reading "Stop vehicle and check power supply"; accompanying this warning was a drastic loss in power. Had I been on the highway I would not have been able to maintain speed with the likelihood of being stranded in an unsafe location. The dealership reported that the ICCU (internal charge control unit) had failed. This is the second such failure on this car. It has been over 4 weeks since the dealership received the car, and Hyundai has not been able to supply repair parts.

The Integrated Charging Control Unit (ICCU) has intermittent failures. During the last failure, my wife was on a busy freeway (Interstate 5 near Hwy 120 northbound) in heavy but fast moving traffic. She was driving in the #2 lane (of 4 lanes) when she experienced sudden loss of propulsion. The vehicle slowed to 5 MPH in traffic that was moving 70 to 80 MPH. She had to traverse through the #3 and #4 lanes to the narrow emergency shoulder. Cars were honking and flipping her off. In the emergency lane, the vehicle completely died after 30 to 60 seconds. She was at risk of being rear ended during the dangerous 5 MPH lane changes and in the time parked in the emergency lane. She could not start the car for 15 minutes, after which the system came back to life. She was then able to start it and continue home. The first time the ICCU failed was in a parking lot. This is a known defect with Hyundai which they have attempted to rectify with Recall Campaign 272. However, they refuse to replace the ICCU. After the first event, they replaced the battery after 22 months/32429 miles. Now they want to replace the battery again after another 20 months/34k miles. What they don't get, is that the batteries have not prematurely failed. Instead the ICCU has intermittently and temporarily drawn the batteries down causing the vehicle to lose propulsion and die. They refuse to replace the ICCU because an error code they were looking for was not in the memory. They have performed three software updates on three separate dealer visits, but the issue has not been resolved. During the last visit they kept my vehicle for six weeks while I appealed through Hyundai Consumer Affairs and the Service manager appealed through his Dealer rep. But the factory engineers held firm and would not approve the ICCU warranty replacement, and instead wanted me to pay for 12V battery replacement. We don't know if there were any warning lights since my wife was busy navigating the danger.

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.

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.
