Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“ICCU failed after 14k miles. Car suddenly went into turtle mode (displayed on dash), car could only go 10 mph and my wife had to pull the car off the street asap and was a very scary experience. Dealer has confirmed the ICCU failure and given me a loaner vehicle. No eta on when the part can be fixed, just that it's current status is back order.”

“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.”

“Car was acting normally. Suddenly, the car would not accelerate. I was on a small road with no place to pull over. Vehicle said to pull over check electrical system. At great risk to my life and the safety of my children, we managed to get to a safe spot before the entire vehicle shut down. We expect that this was a failed ICCU.”

NHTSA complaint #11721849, filed 2026-03
