The Hyundai Ioniq 5 advertises quick charging via level 2 (240v) supporting nearly 10 amps. Hyundai has acknowledged by issuing a TSB this year that the charging port overheats at high amperage and causes charging to cease before the battery reaches the intended state of charge. The TSB addresses the issue by slowing the rate of charge substantially when the port overheats. As a result, owners are unable to "refuel (charge)" the vehicle at the advertised rates. In addition to the overheating charge port posing a potential hazard, the result is that an uninformed owner may not have necessary charge to reach their destination.

Ioniq 5 continuously fails to complete charging when on level-2 EVSE. Charging port and plug feel extremely warm to the touch, even in cool ambient weather. Multiple UL-listed charge cables yield similar results, while working perfectly well with other EVs.

My partner was driving my car on Tuesday, May 23, 2023 and received a "Check Electrical Vehicle System" warning. Within 30 minutes of receiving that warning, the maximum speed on the car was throttled to 20 mph and shortly after that, the car stopped working entirely. Thankfully, my partner was on a residential street when all this occurred and was able to move to safety; however, had any of this happened in a highway driving scenario, the results could have been catastrophic. My car was towed to a dealership that same evening and it has been with the service department since then. The two parts on backorder they are waiting on on the ICCU Assembly and a High Voltage Fuse. Upon searching for other Hyundai IONIQ 5 owners with similar issues, various internet forums are filled with reports of similar things happening. At this point, I have been told this part is on backorder for potentially up to 6-9 months and after repeated calls with the dealership and the corporate office, Hyundai has not acknowledged the extent of this issue, the potential safety concerns, nor offered any relief for being without my, basically brand new, car for the remainder of this year.

This is an electric vehicle that features “iPedal” driving, what Hyundai refers to as one-pedal driving. The main safety issue is that when you decelerate using one pedal, which is a fairly aggressive deceleration, the brake lights do not come on unless you lift your foot entirely from the accelerator or apply the brake pedal (which one would rarely do in iPedal mode). Hyundai needs to rethink their concept of operations for how their brake lights should operate. People are at risk of getting rear-ended. I didn’t realize this was how the vehicle operated until I was almost rear-ended today. Please push them to fix this issue.

The 12-volt battery that controls everything in the car stopped being recharged by the 800volt battery, eventually causing the car to suddenly lose power and slow to 22 mph on the freeway. I was able to pull over 3 lanes and exit what was fortunately an uncrowded freeway. The car would not exceed 22 mph and soon stopped altogether and could not be moved. The main 800volt battery was at 56% charge, as the 12-volt battery went to 0%. The car was towed to the dealer. After inspection the dealer has confirmed that the ICCU system has failed and must be replaced, with a long back order and still no delivery date after 5 weeks. There were warning messages that appeared before the vehicle lost power, saying to check the battery electrical system. There should have been a warning that said “stop driving immediately as the electrical system is failing, and the car may stop even though the main battery is still well charged.”

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

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.
