While the vehicle was parked in a garage and charging overnight, I briefly went to the vehicle to retrieve an item from the back seat. I was barefoot at the time. I opened the driver‑side rear door and reached inside with my right hand while my left hand was near the upper door area where the door seal is located. When my left hand grazed the door frame, it felt unusually sharp. When I touched the area again to determine what was sharp, I received a significant electric shock. There were no warning lights, messages, or prior symptoms before the incident. The presence of electrical current on an exterior door surface poses a safety risk during normal vehicle use.

I was traveling on the freeway when I got a warning saying “check electrical.”i started to pull over on the freeway and my car went into “turtle mode “and I made it off the offramp but almost got rear ended. I was half a mile from home so I limp home in a tow truck towed off. It was determined it is the ICCU.

ICCU failed second time wednesday february 18, 2026. First ICCU failed November 2024 and replaced under warranty. The car went in turtle mode.....20 mph or less. Limped along safely on side of roadway and used sideroads. The dealer says the ICCU and fuse need to be replaced. The dealer wants me to pay for this part, third time is a charm? I don't think I could ever trust this part again. They want to give me the exact same part they gave me when the ICCU failed b4. There were 2 messages: stop vehicle and check power supply ......check electric vehicle system. They were timely and made this failure a bit safer. The dealer inspected the vehicle but not the manufacturer or anyone else. The car is at Balise Hyundai Fairfield CT I BELIEVE 10% OF THESE ICCUs ARE DEFECTIVE.

The Ioniq 5 has a known issue with a part called the ICCU. When the part fails, which it seems to inevitably do despite multiple recall repair visits and software upgrades, the car ceases to be driveable. In advance of this moment when your multi ton vehicle turns into a brick you get a short warning saying pull over, but that is not always possible. The car starts loudly beeping and reduces its max speed to 12 mph, which is not great on the freeway. The ICCU is a huge safety problem, a known issue that Hyundai is well aware of, and the part needs to be redesigned and the NTSB needs to force Hyundai to extend greater warranty protections for this event. This just happened to me, the dealership says they have 8 other ioniq 5's in with the same issue and I am number 9 on an ioniq 5 iccu loaner car waiting list while the part is back ordered for at least one month. My car stopped at a stop light and fully blocked an intersection when it bricked as I came off the freeway, was super scary to sort out in the middle of the road and I was very happy that my twin toddlers were not in the back seat, i was not so happy I had to pay to have the vehicle towed and arrange a comedicly complicated way to pickup my kids due to this known issue parts failure.

The component that malfunctioned is the Integrated Charge Control Unit (ICCU) and related high-voltage charging system in my 2022 Hyundai Ioniq 5. The ICCU controls AC (Level 2) charging, DC fast charging functions, and power delivery. The ICCU assembly and charging components were serviced and replaced by an authorized Hyundai dealer and are available for inspection through service records. This defect created a safety risk because the vehicle experienced complete charging failure and reduced-power operation. Loss of charging capability can leave drivers stranded, and reduced-power “turtle mode” conditions can limit acceleration and vehicle performance, creating hazards in traffic. The charge port has also not locked during charging, creating a potential risk of electrical arcing during DC fast charging. The failure was reproduced and confirmed by an authorized Hyundai dealer. In approximately January 2025 the vehicle would not charge and remained at the dealership for an extended period (about January through June 2025). After diagnosis and consultation with Hyundai technical support, the dealer replaced the ICCU assembly and high-voltage fuse. The vehicle and charging system have been inspected multiple times by Hyundai service centers. Hyundai issued recall campaigns in 2023 and 2024 involving ICCU software updates and fuse-related work, but these did not prevent the later failure requiring full ICCU replacement. Prior symptoms included abnormal charging behavior and eventual total loss of AC charging capability during the 2025 failure, making home charging impossible. After the ICCU replacement, the vehicle exhibited unusually loud cooling fan operation during Level 2 charging, documented by the dealer. There were also charging-port safety concerns. After one service visit, an important DC pin cover/cap was not properly installed until corrected on a return visit, leaving charging components exposed.

Ok.... So, if anyone reads about Hyundai Electric line.... Ionic series... they would know that since Day 1, Hyundai has had problems with their electrical system. It 1st started with the system never charged the onboard standard 12V battery. I had to purchase Jumpstart boxes, I couldn't run my car ever on acc bc since day 1, my car has never been charging the onboard 12v battery. This caused me to not be able to start my car on more than 5 occasions. I had to ask strangers for help at times, locked out of my car on the side of the street, in parking lots, driving to Auto Zone after a complete trickle charge didn't work bc battery is so drained. During this drive, my cars safety features wouldn't work correctly, everything blinking and i had to make it to Auto Zone to have to buy a new GSM battery. I feared for my life on that drive. Certainly a safety issue. When I asked Hyundai on numerous occasions, they said there's no way for us to test if the recall fix we did actually is helping the issue. So I had to buy my own DC volt meter. I took that car in 4 times to deal with this issue. Now, after my last visit to Holler Hyundai in Winter Park a few months ago, now my car won't charge at home. I tested it with the 2nd charger. F2 fault code on standard home charger. Red lights on my ChargePoint charger. Car charges fine at DC Supercharger (6 times as expensive). I have told Daytona Hyundai multiple times (General Manager knows me) about how I have taken this in to have this problem fixed on many occasions. The GM said he apologizes, doesn't know why it wasn't fixed, they were unprofessional aside from him making many mistakes. The original dealer i bought it from was a bad experience and I do not trust them at all and would not buy from them ever again. I have video and pics of spiders in my car/roaches, etc. Dealership didn't even respond after I emailed them pics. I have bought and owned over 30 cars. This definately needs attention

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

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.
