Other or unknown: “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. …”

NHTSA complaint #11719923, filed 2026-02

Transmission and drivetrain: “The ICCU assembly and high voltage fuse blew/broke at 6,255 miles as I was driving on Interstate 294. That immediately reduced the vehicle maximum speed to about 25mph, causing a hazard to myself and following drivers who were traveling at 55mph or more. I limped about 3 miles to the next exit, where Hyundai arranged for a tow and warranty service to replace the faulty parts. There were no prior symptoms or warnings. …”

NHTSA complaint #11709687, filed 2026-01

Fuel system: “While driving check electrical system warning appeared and vehicle went to limp mode limited to 20mph while on a 40mph roadway. Drove an additional few miles to try and reach home and vehicles completely died, no power. Towed to dealer. DTC P1A9096 indicates ICCU failure”
