The car engine shutdown mid drive. One minute before the complete stop, the car was stalling every 20 sec or so, then the acceleration stop responding to the drive pedal. The car was gliding to a stopping point. The "Engine " warning was on the display. Afterward, the car was towed to the Earnhardt Hyundai North Scottsdale, where the service center could not recreate the problem. They concluded that is a non issue since they did not observe the same issue during the test and diagnostic.

What owners say
The contact owns a 2024 Hyundai Ioniq 5. The contact stated while driving at an undisclosed speed, the vehicle stalled and failed to return to normal operation. The "check the battery" message was displayed on the instrument panel. The vehicle was towed back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,240.
Routine Friday morning and just finished charging my 2024 Hyundai Ioniq 5 at Walmart. As I started my vehicle to finish my commute to work, the dreaded "Check electric vehicle system" warning light came on along with a red battery icon. There were no warning signs or anything that could have foretold what would be happening. I pulled into an empty parking stall and called the Hyundai dealer for advice. I was told not to drive the vehicle and get it towed to the dealership. After being diagnosed, my car will need a new ICCU and ICCU fuse. The dealership gave me no ETA as it often takes weeks to months to receive the parts from Korea. I was told Fontana Hyundai had 9 other cars with the same ICCU issue in line before mine. I was so glad it occurred in a parking lot and not on the freeway since a malfunction with the ICCU will basically cause the car to loose total power and control. This is definitely a huge concern and safety issue.
The car stalled while being driven by my son. It displaced an error code. The Car had to be towed to dealership. It was diagnosed with ICCU unit failure. Needs to wait over a months for parts.
My car gave me a "Check electrical vehicle system" message, which I have seen online may mean a problem with the ICCU. As the dealership is close - about five miles from my home, on residential roads - I decided to drive there. The car lost power very quickly and then died in the road shortly after leaving my driveway. Thankfully I wasn't on a busy street or an intersection and was able to safely get it to the side of the road, but if it had died while driving at a higher speed it would have been very dangerous.
The ICCU system's fuse failed.The car is currently with the dealership for repairs and could be available for inspection there if needed. The car was rendered inoperable and shut down while operating the vehicle. The abrupt breakdown could have been a hazard to the driver, passengers of the vehicle, and other drivers on the road. The issue was confirmed by the dealership's service technician. The vehicle has only been inspected by the dealership's service department at the time of writing. There was a warning just before the system/car shut down while driving. The warning sounded and said to "Stop vehicle and check power supply." This was the only time the warning appeared.
The ICCU has failed. This component was replaced approximately one year ago as part of a recall, but it has failed again. The vehicle is currently parked and cannot be driven until Hyundai provides a replacement part, which may take up to three months. The failure presents a safety concern, as the vehicle can shut off while driving and leave the driver stranded. The Hyundai dealership has confirmed that the replacement part provided by Hyundai—the ICCU—is the component that failed. There were no prior warning signs of failure, other than the vehicle refusing to charge on a Level 2 charger.
Battery electrical system, car gave warning to stop and park immediately , and stalled in the middle of the street while trying to make a turn, with no way to move it, or put it in neutral.
ICCU unit died while driving. Very sudden - I got a message on dashboard to check the electrical system (and how am I supposed to do that on my own while driving?). Within a few minutes system tells me power was reduced (I had 85% charge), within a minute or so after that system starts telling me to pull over. Happened in town so I got to a paring lot and called service -- but the speed and cryptic nature kind of set me aback.
The contact owns a 2023 Hyundai Ioniq 5. The contact stated that while driving 4 MPH, the vehicle lost power and stalled a mile from the residence. The message "Check Electrical System" was displayed. The hazard light was activated but quickly became inoperable. The contact called AAA towing, where a power booster was attached to the vehicle, and the vehicle was restarted. The contact was able to drive back to the residence. The AAA driver indicated that he had towed eight other similar vehicles to the same local dealer. The vehicle was towed to the local dealer, but was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 16,000.
