I was able to get it home and then towed to the local dealership. I was told it was a issue with the ICCU and that it, along with my 12V battery and ICCU fuse, needed to be replaced.…

I heard a pop sound in the back seat while pulling into a parking spot and got a "stop Vehicle and Check Power Supply" and it going into limp mode. I was able to get it home and then towed to the local dealership. I was told it was a issue with the ICCU and that it, along with my 12V battery and ICCU fuse, needed to be replaced. They could not tell me why the ICCU failed. This was on 1/3/26 and as of today 2/06/26 the dealership is still waiting for a replacement ICCU.
ICCU failure
I heard a loud pop and then the dashboard was flashing with a lot of warnings. The car slowed down to about 5 MPH and then eventually died and wouldn't turn back on
12v Battery has died multiple times. Dealership says the battery is fine. 2025 with 16k miles.
The ICCU failed after 5,500 miles and the car lost all power. Fortunately it happened in the driveway and otherwise could have been a life-threatening situation. This is a 2025 model that wasn't covered by the recall so it's obvious Hyundai has not solved the problem.
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 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.
I was at the grocery store and when I returned to my car and started it, I had an error message on the dashboard regarding the vehicle battery. When I put it into reverse, I heard a loud pop and received another error message. The car would only drive at 25 mph after that. I tried to drive home but the car died after a few miles…

I was at the grocery store and when I returned to my car and started it, I had an error message on the dashboard regarding the vehicle battery. When I put it into reverse, I heard a loud pop and received another error message. The car would only drive at 25 mph after that. I tried to drive home but the car died after a few miles and I was stranded at the side of the road. It was towed to a dealership and I have been told that it is an ICCU failure. At this point, I have been waiting 3 weeks for it to be fixed.

On [XXX], the vehicle was unable to be started - no lights, no power, unable to open the doors. I called Hyundai Roadside Assist and they sent someone from AAA a few hours later who was able to "jump start" the vehicle. I took it to the dealer, Manly Hyundai, on December 17th, 2025 and they determined nothing to be wrong with either the battery or the electrical system. On [XXX], while driving from home to the local grocery store, the car presented a warning light on the dash and the “gas pedal” stopped working. I was able to coast into a parking lot at which point an even larger warning light appeared and the vehicle then lost all electricity completely. I again called Hyundai Roadside Assist and they sent someone from AAA a few hours later who determined that the car was unable to be “jump started” and would have to be towed to the local dealer, Manly Hyundai. The dealer reported back to me that the component that failed is called an “ICCU” and is some kind of controller related to the charging and motors of the electric drivetrain. It is available to be inspected at the dealer currently, Manly Hyundai. My safety was put as risk because the car became essentially inoperable while driving downhill and gave no warning signs ahead of time before the lights lit up on the dash and I lost control. The dealer has confirmed that it is an issue with the “ICCU”. The dealer has inspected the component at their service department. The first warning light that appeared came at the same instant that the vehicle lost drive power. The second warning light that appeared came at the same time that the vehicle lost all electricity entirely. There were no indications that something might be wrong with the vehicle prior to the vehicle actually producing symptoms of being undriveable.
