On 3/22/23, after using my car most of the day, I started my car to leave work and heard a small pop noise and a warning appeared on my dashboard to 'Check Power Supply'. As I was relocating to another parking spot, the car gave an audible beeping warning and another warning appeared on my dashboard to 'Stop Vehicle Immediately and Check Power Supply'. After speaking with the dealership, it was determined that my car had to be towed. I did not experience any loss of power/speed because I was only in a parking lot. The dealership informed me the next day that the car needed a new fuse and ICCU, but that the part was on backorder and they did not have an estimate on when they may get the part in. Repairs to my vehicle were completed on 5/3/23 (6 weeks) later. Hyundai did agree to reimburse me for the cost of a rental vehicle, but did not reimburse me for the gas expenses that were incurred that I otherwise would not have had.

My car is unable to charge at the advertised 48A charge limit due to overheating of the charge port. Once I start charging, within 30 minutes to 2 hours the car will stop charging abruptly. It appears this is due to the AC Inlet port sensor reading 212F degrees when the issue occurs. The car is advertised as having 48A charging and if it’s not capable of this, Hyundai needs to resolve it.

On Monday Jun 19 2023 around 7pm PT while I was parallel parking, I heard a pop from the engine area and immediately saw the center console show a warning message (one beep, then no further beeps): “Check electric vehicle system” I finished parking and left the car running while I starting to investigate online what this error meant. After ~2 minutes parked I got an active alarm (beep beep beep beep) that said “Stop Vehicle and Check Power”. I turned off the car. The battery was at 22% at this time, with about 44 miles of range. BlueLink Vehicle Diagnostic accessed from the in-car infotainment system said no issues found. The MyHundai App Diagnostic Report on my Android phone said All Systems Normal. On advice from a Hyundai dealer that I could drive 2 miles home, so I did. When the car started I saw the warning “Check electric vehicle system” and made it about 5 minutes before I got the active alarm “Stop vehicle and check power” I turned off the car and turned it back on and finished the 5 minute drive home. Thursday of the same week, the Android app continued to say All Systems Normal and on the same day I paid to have the car towed to a Hyundai dealer. Today, July 10th, I finally got a call back from the Hyundai dealer that the ICCU (Integrated Charging Control Unit) was in need of repair and that they have no ETA for when the part will come available. I do appreciate that they offered me a loaner car during the wait, however long that will be. I saw on the NHTSA website that there was an active investigation into a similar issue, and wanted to share my story.

This time the vehicle did not start. Had the vehicle towed to a local Hyundai dealer. Hyundai dealer took 2 weeks to diagnose the problem. Was advised by the dealer that the ICCU module needed to be replaced along with fuses, and coolant. Also noticed vehicle having slow acceleration at times after charging. Also notice a weird noise on right rear passenger side of the vehicle sounding like fluid pumping at times. Vehicle has been at the dealer for 27 days and still not repaired

The car showed 67% battery life. But it would not charge any further. When we plugged it in, the voice would say "Charging Unsuccessful". The dash had the 'check electric vehicle' system error and when we tried to drive it, we got the red 'stop vehicle' error and alarm. We parked the car, called the dealership who made an appointment to have it diagnosed and told us not to drive it in the meantime. When it was time to take the car into the dealership, I turned it on and got 'turtle mode' and couldn't accelerate past 5mph and had trouble controlling the steering. I got about 100 ft past my driveway and the car completed powered down. It had to be towed to the dealership. When this car powers down, you can't do anything, you can't roll down the windows or unlock the doors or get the car in neutral. The tow truck driver had to use a portable battery and jumper cables just to power the car on so he could get it in neutral which releases the parking park so he could pull it on the flatbed. The dealership said our integrated charging control unit (ICCU) needs replaced; the part is on back order with no ETA. So, they have our car, and we're driving a rental and paying for gas again.

PE24028 · 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.
