Our 2023 Hyundai Ioniq 5 went completely dead on the evening of [XXX]. There were no warning signs/messages prior to it. It just would not start and none of the electrical systems (dashboard, lights etc) worked either. We became aware of the recall involving defective ICCU causing depletion of the 12 volt battery. We called nearby dealerships but their service departments were closed because it was the weekend. On Monday January 13, 2025, we were able to get in touch with the Hyundai dealership in El Monte, CA. Their service personnel instructed us to jump start the car and bring it in for service, which we did around 8am the same day. Around 2:30pm, we received a call from the El Monte dealership saying that they are not able to address the issues with our car because the dealership who sold us the car (Garden Grove Hyundai), had installed/wired a non-factory-certified GPS device (LoJack) into our car (unbeknownst to us), which was interfering with troubleshooting. The El Monte service person recommended that the car be transferred to the Garden Grove Hyundai dealership. He also stated that he would not recommend driving the car to the Garden Grove dealership since it may pose a safety risk. He said that it's possible that the car may suddenly die without warning while we are driving. We spoke with Hyundai roadside assistance, Hyundai customer care, and then the Garden Grove dealership, only to be told that it is not their responsibility to transfer the car, despite it being a safety risk to drive the car. The Garden Grove service person kept insisting that it's safe to drive the car and to just drive it over, which made us extremely uncomfortable. Nobody has taken ownership/responsibility for what has happened and the customer service has been awful. We have wasted the entire afternoon of January 13, 2025 being on numerous phone calls with no resolution in sight.

There was no major safety issue in this instance. My concern is this poses a severe risk if it happened while driving. The car was on and in ready to drive mode but was parked in the garage with climate control on while loading it for going to school. At somepoint between trips to the car over 20 minutes it died with no warning. Some lights behind buttons, the interior lights, and the screens were on but blank. Not a single button in the car would respond. Including hazards or opening the trunk or closing the charging port door. Lights like the LED for the overhead light button blinked and the charging indicator by the charging port blinked a pattern of 1 longer flash and 8 shorter flashes. The car would not shut off or on again another button that was completely unresponsive. The lights and screen stayed on for at least 30 minutes before I left with a Lyft to get the kids to school. An hour and a half later everything was off and it seemed to have no power. At that point I did figure out how to jump it and get it to the dealer. The dealer claims the 12V battery died and that was the only issue and completed the 2 open recalls. There was no indication when I started the car that anything was wrong or the 12v battery was low or needed replacing. There are apparently no error codes from it completely failing while in ready mode. I was only told this happened because it was in park and the 12V battery failed while it was on and parked, if I had been driving I would still have use of the vehicle as the recall outlined for a failed ICCU when the 12V battery drains. They can find nothing else wrong but my concern is that a failed 12V battery could cause this while driving. I was told simply it cannot happen because the software handles it differently when driving. I hope that is correct.
Hyundai service department confirmed the ICCU needs to be replaced but is on back order for 5-6 weeks
The car has had multiple recalls for the ICCU failure. I have brought the car in been 3 times. Will go in again this week . The recall remedy never fixes the issue. The car works for a few weeks then the same issue happens again .Unable to start the car or drive . Has been going on since June 2024.

Several days ago, the twelve volt battery on my car was replaced because the car just suddenly died overnight while sitting in my garage. They told me that the battery needed to be replaced when I went to the dealer. They replaced it and now less than a week later, I was driving on the highway and suddenly the car Slowed to no more than 27 miles an hour with warnings about the electrical system not working and a problem with the battery. I had to put my flashers on while I was driving down the highway until I was able to pull off and have the car towed to another dealer that was closer to the scene. Not sure what they are going to say, but obviously this was very scary as well as a nuisance.
I was sitting in my parked vehicle, which I had just turned on. It was cold so I turned on the seat warmer. About a minute later, I hear a pop and saw a “check electric vehicle system” warning on my dash, followed by an audible alarm and a new “stop vehicle and check power supply” warning on the dash. I decided to have the vehic…

I was sitting in my parked vehicle, which I had just turned on. It was cold so I turned on the seat warmer. About a minute later, I hear a pop and saw a “check electric vehicle system” warning on my dash, followed by an audible alarm and a new “stop vehicle and check power supply” warning on the dash. I decided to have the vehicle towed to my local Hyundai dealer.
While driving on a 45 mph speed limit road, there was a "pop" noise and then alarms on the dash display that power was limited and stop the car. The car's speed was severely limited to about 10 mph for a few seconds while I pulled the car over, and then the car died. Everything was electrically dead. I couldn't even turn on t…

While driving on a 45 mph speed limit road, there was a "pop" noise and then alarms on the dash display that power was limited and stop the car. The car's speed was severely limited to about 10 mph for a few seconds while I pulled the car over, and then the car died. Everything was electrically dead. I couldn't even turn on the hazard lights or lock or unlock the car. I took a video of the dash display rapidly alternating between two alarm messages, "12V battery storage low. Stop safely." and "power limited." This website wouldn't let me upload the video, so I saved screen shots of the two alarm messages from the video. Shortly after I stopped the car, it all went dead. It scares me to think what would have happened if I had been on the interstate when this occurred.
I was driving the car 70 miles per hour in a highway. Car suddenly stopped and only go 5 mph. I was lucky no car behind me. If not I could be death today. I brought it to service and ICCU unit failed which is happened almost all Hyundai IONIQ 5. They replaced it with same ICCU and it will happen again. I think they want me to…

I was driving the car 70 miles per hour in a highway. Car suddenly stopped and only go 5 mph. I was lucky no car behind me. If not I could be death today. I brought it to service and ICCU unit failed which is happened almost all Hyundai IONIQ 5. They replaced it with same ICCU and it will happen again. I think they want me to make an accident next time. This car is not safe to drive with this charging unit.

1PE23011 · 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.
