IllustrationThe ICCU in the car failed. It immediately limited the speed of the vehicle to 25mph. There were no warnings, it happened all at once. I had to drive on the shoulder of the interstate to the next exit. Obviously, driving 25 on the shoulder while cars passed me at 65+ was not a safe situation.

My EV’s ICCU failed. It has since been fixed and is not available for inspection. Yes, my safety was at risk because my speed was suddenly limited away from home and I had to get my family home. After a wait of about 3.5 weeks, the dealer confirmed it was an ICCU failure and replaced the ICCU about one week after that. There were no warnings until the failure occurred. I believe Hyundai’s ICCU problems are well-known, but want NHTSA to be aware.
ICCU failed while driving. Risk was that I suddenly had to pull over safely, as my car would no longer accelerate. This is a known issue, yet they haven’t fully addressed it over years. I had it taken in for recall fixes, and the part still failed 2 weeks later. There was no warning before it happened. But failure signs appe…

My vehicle was affected by Recall 272 and in December 2024 only the software for the ICCU was updated. Now the ICCU is bad and Hyundai wants to give the run around and say that my vehicle wasn't affected by the recall. It clearly was and they need to make it right. My car is currently sitting at the dealership that I bought it from and I feel like they are not trying to do anything to help. I have called each day to get an update and all I get it, "we are still waiting". I am beyond frustrated at this point.
On January 31, 2025, my 2022 Hyundai Ioniq 5 experienced a failure with its ICCU resulting in the vehicle to lose all power and become unable to be turned on exposing myself and others to conditions where the vehicle could become a serious safety hazard due to its complete lack of power.

On January 31, 2025, my 2022 Hyundai Ioniq 5 experienced a failure with its ICCU resulting in the vehicle to lose all power and become unable to be turned on exposing myself and others to conditions where the vehicle could become a serious safety hazard due to its complete lack of power. This occurred despite the application of the NHTSA Hyundai Recall 272 only two weeks prior to this incident which was supposed to prevent this serious safety defect from occurring. The vehicle's 12 V battery was subsequently replaced allowing the vehicle to display a "Check electric vehicle system" warning. The dealership has since confirmed this as the ICCU defect. No warnings or other messages preceded this incident.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the electrical charger was overheating, and the 12-volt battery was draining without warning. The contact stated that while charging the vehicle, the contact heard an explosion. The contact stated while driving 20 MPH, the message "Stop Driving Immediately - Return to Dealer"; the check engine warning light illuminated, and the vehicle experienced a loss of automotive power. The contact stated that on one occasion after turning off the vehicle, the battery remained active for 3 days, causing the battery to become drained. The vehicle was taken to a local dealer where the vehicle was diagnosed and the contact was informed that the water pump, the EV battery, the charge point, the inside batteries, the sensors, the navigation system, were faulty and needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The approximate failure mileage was 65,000.

My 2022 Hyundai Ioniq 5 has experienced numerous 12V battery failures since early 2024. I ended up having to replace the 12v battery five separate times. The car fails to start with no warning. It has stranded me while transporting a pregnant spouse and a sick infant. Each failure required a tow and service visit. Hyundai claims “battery case corrosion” is to blame, but this is clearly a systemic electrical defect affecting many owners. This is a critical safety issue for families relying on the vehicle in emergencies. This is a safety and accountability issue affecting many families.

Driving on the highway/freeway, received an error message on dashboard "stop vehicle and check power supply". The car slowed down, max speed around 45 but thankfully my hazard lights still worked and I exited the next exit. I've heard I was lucky as some people with the same problem - the car goes into "limp" mode and slows down to 5mph or stops completely. Very unsafe on a highway for everyone. Dealer has checked the vehicle and states it's an ICCU problem

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.
