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 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.

We were driving our vehicle in a parking lot while on vacation and we got an error message “check electric vehicle system”. It then displayed the error message “stop safely and check power supply”. Four months ago, we had the same problem and had our 12 volt battery replaced and our ICCU updated. Our vehicle lost power while we were driving. We were able to drive the car safely to a hotel. But the ICCU needs to be replaced.

My new 2023 IONIQ 5 became inoperable on 3 occasions when it completely lost power. This situation unquestionably impaired my safety on the first occurrence of power failure that happened without warning while I was driving; fortunately, I was able to coast to the side of the road without incident. In my repair visits to Hyundai dealers, the integrated charging control unit (ICCU) updated (twice) and the depleted 12-volt battery was charged. Repair visits resulted in loss of use of my car for a total of 31 days while it was in service. The 12-volt battery finally had to be replaced on the last dealer visit because it had could not hold a charge. The battery was barely a year old. No Hyundai dealer could assure me that the problem with the charging system was resolved. It was suggested that annual replacement of the 12-volt battery before the end of its normal lifespan might be required to avoid the serious safety risk of power failure while operating the vehicle. Hence, I am not driving my car with confidence that the safety risk risk was alleviated. I understand that Hyundai Motors acknowledged the ICCU problem and addressed it with a new ICCU in the 2025 Ioniq 5 model year. However, in my case, I have a still-new, expensive vehicle that I drive without feeling 100 percent secure that I am safe.

I started my car and after a minute I received a warning saying to check my electrical system and safely pull over. After 5 minutes of trying to drive to the dealership the car suddenly slowed down to a max speed of 27mph and then shortly after slowed to a stop and turned off. The car would not turn on and eventually the 12v battery died. I tried to jump the car but the 12v would not stay charged long enough to put the vehicle into drive. It appears the ICCU is not working and cannot keep the 12v charged to make the car function .

Vehicle disengaged lane keeping ADAS without warning multiple times. Sometimes a warning beep would occur, but often on turns it would suddenly disengage without a beep or any other warning method causing me to have to yank the wheel to complete the turn correctly and avoid running off the road. This has caused me to not trust the system and fight the lane keeping feature just in case it suddenly turns off and goes into the other lane before I have a chance to correct the steering.

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.
