2025 Hyundai Ioniq 6 Complaints

ICCU failure. Sudden total electrical shutdown. According to this site, there was a recall filled but NOT COMPLETE since November 2024! We are now February 2026. There has been NO warning issued to Hyundai consumers about this. When the ICCU fails, it puts consumers at risk. When it happened to me, there was no shoulder to pull onto. Because there was a snowstorm that morning, the flatbed tow truck did not come for 3 hours. My car was in the shop for 3 days. The bottom line is that the failure of communication about this defect puts consumers at risk!

My leased 2025 Hyundai Ioniq 6 experienced a sudden malfunction resulting in loss of vehicle operation. The vehicle has been at the dealership with delayed diagnosis and no clear repair timeline provided. This appears to be a safety-related defect involving the electric system. I am aware of multiple reports and recent news coverage describing similar failures in Hyundai/Kia electric vehicles related to ICCU (Integrated Charging Control Unit) defects, which can cause sudden battery discharge and loss of propulsion. Media reports indicate that this defect has affected numerous vehicles and, in some cases, repairs have taken more than a month due to part availability and diagnosis delays. My vehicle experienced similar symptoms, including loss of power / inability to operate normally, and the dealer has not been able to promptly resolve the issue. This appears to be a broader safety-related defect rather than an isolated incident.
