I tried to start car and it started but would not go into drive. A message saying "12v battery voltage low. Stop safely." Was on the screen. I turned the car off and back on and was able to drive home. Once home I tried to charge the car but it would not charge. However I left it plugged in and came back several hours later and the car had charged some. I started the car and the messages did not appear. The next day i went to drive the car and the car was totally dead. The auto key would not unlock the car. Thank goodness , I was not driving when the battery died. I took it to the dealer. This is the 2nd 12v battery I have had to replace in 4 years. The first replacement was covered under warranty. I asked them to try to identify the root cause of the 12v batteries dying so quickly and they claim it is only the 12v battery. I feel unsafe driving the car now knowing it could happen at any moment again, maybe while driving. I think the problem is related to the ICCU as my symptoms are very similar to other people with ICCU issues.

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.

2022 Ioniq 5 SE. ICCU failed April 2026 with around 29325 miles. Original owner. Purchased June 2022. I had the original Recall 272 software update performed back in February 2025, but the hardware still failed a year later. **Timeline of Failure:** 1. **Phase 1 (The Trigger):** Level 2 charging stopped unexpectedly before reaching the limit. It tripped my house breaker and unfortunately killed my Level 2 EVSE (Grizzl-E) with a stuck relay. Didn't think too much of it because I had to be somewhere. Car started up normally and I was able to drive throughout the day with no problems. 2. **Phase 2 (The Warning):** The next day, I attempted Level 1 charging. It immediately tripped the breaker. I tried another outlet on a different breaker; the breaker didn't trip, but the car failed to initiate a charge after three attempts. 3. **Phase 3 (Dashboard Error):** After third failed attempt with the L1, I took a peek inside and saw the dashboard had a yellow triangle. With the charger still plugged in, I sat in the driver's seat and turned the car on. The **"Check EV System"** error appeared. I turned off the car and went inside to call the dealer. I called the dealer and they said I can have it towed there. They also scheduled an appointment for the next morning. I went back to car to attempt to position the car to make it easier for the tow truck, but the check ev error was not there when I turned on the car. It said ready and I was able to drive around the block a few times so I figured I'll just try to drive to the dealer. I drove the car to the dealer the next morning. It took **one week** to get my car back. **Diagnostics & Parts Replaced:** The dealer confirmed the following codes and performed a full hardware replacement: * **DTC P1E1300:** AC Power Module Failure * **DTC P1A9096:** DC/DC Converter Fault * **ICCU Part:** `36400-1XAA0-AQQH` * **HV Fuse:** `375F2-GI040-QQH` * **Coolant:** Install of Pink Antifreeze (`00232-19098`)

The 2022 ioniq 5 was bought used with 43k MI and within 2k miles of driving in 50-85F climate and 7kwh l2 charging I witnessed the orange check EV light flash while I was driving on the highway. I exited and powrr cycled the car and the EV light remained. The next morning the orange check EV light was gone. I went to the dealership for a diagnostic and they said they could not replicate the error code or had found any history of the error code coming up without proving to me or showing me any substantial evidence that they tested for anything at the Escondido Hyundai dealership in California. I escalated the issue with Hyundai corporate and was assigned a case manager that ultimately gave me the same answer that they could not replicate any codes and that I should take the car back and drive normally. After extensive research I found that the orange check ev light is a more dangerous sign than the red check ev light because it indicates that the ICCU unit is about to fail. Research shows that due to thermal stress the ICCU will inevitably fail after the orange check AV light comes on. Further research shows that Hyundai had officially stated a 1% failure rate for the ICCU unit in all of their EVs built on the e-gmp cars to date but some projections are at 10% failure rate or higher and that Hyundai Kia is downplaying the issue similarly to how they tried to do the same with the Theta 2 GDI engines that they had been sued and were responsible to pay over $300 or so million dollars as well as $24 million to a employee whistleblower a few years ago. I highly suggest that the nhtsa or other organizations that have the power to force Hyundai Kia to do the right thing so that no further lives are at risk from these ICCU units that have flawed designs that have not been fixed,only remedied via software update or replaced with refurbished units at the most with inevitable failure as thermal stress is experienced.

In summer 2025, the ICCU (Integrated Charging Control Unit) failed and was replaced under a Hyundai recall at no cost. On December 4, 2025, warning lights reappeared. College Park Hyundai diagnosed a faulty battery related to the prior ICCU failure. I paid out of pocket for a 12-volt battery replacement and additional maintenance, as the dealership claimed the battery was not covered. A “Check Electric Vehicle System” warning appeared immediately after I picked up the vehicle that same day. On December 5, 2025, I returned the vehicle to College Park Hyundai with 20,415 miles. They diagnosed a failed main EV drivetrain battery requiring warranty replacement. As of April 5, 2026, my vehicle has been at the dealership for 122 consecutive days with no repair completed, no replacement battery received, and no estimated completion date. Despite repeated follow-ups, I have received no meaningful updates on repair status or battery availability. I have been without my vehicle for four months with no resolution in sight. This extended delay represents a significant safety concern and an unacceptable failure of Hyundai’s warranty obligations.

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.
