“We heard a pop noise and then received low 12 volt low battery warning. The Integrated Charging Control Unit (ICCU) might be the root cause of the Hyundai Ioniq 5 electric vehicle. Car went into slow turtle mode and we could barely move the car. we pulled over and found a safe spot to park car. we had car towed to Hyundai dealership since car was not operational.”
NHTSA complaint #11712305, filed 2026-01“As I began a drive cycle, I heard a pop sound and received the “check electric vehicle system” warning associated with ICCU failure. With ICCU failure, if I had continued to drive the 12V battery would have run to zero and the car would have died completely. Vehicle goes to dealer tomorrow for confirmation.”
NHTSA complaint #11733152, filed 2026-04“Warning light came on stating that we needed to have the electrical system checked asap. Vehicle would not charge from Level 2 charger. It needed to be towed from our house to the dealer to get its ICCU replaced since there was a risk that it would no longer power vehicle on 4 mile drive to dealer for repair. Problem was fixed in one week by Roseville Hyundai by replacing the ICCU in the vehicle”
NHTSA complaint #11714317, filed 2026-01“When I started driving my car a warning to check the electrical system came on the display and the speed of the car dropped to less than 25 mph. The road we were driving on was over 45mph without a safe shoulder. After it was towed to the dealer, they diagnosed that the ICCU had failed and replaced it and a fuse. This was after all recalls and other software updates were performed many months ago.”
NHTSA complaint #11705960, filed 2025-12“I was driving and the car gave an electrical system warning, slowed, and thereafter would not go above about 20mph. Fortunately this happened on a local, low speed limit street. I'd rather not think about what might have happened if this had happened on a highway. The Integrated Charging Control Unit (ICCU) is no longer working as it should. The problem has been confirmed by the dealer/manufacturer service station.”
