Consumer Description

The ICCU (Integrated charging control unit) failed, causing my car to go into "Limp mode" where it was unable to accelerate over 44 mph. This put my safety at risk as I was unable to accelerate on the freeway. The Hyundai dealer confirmed the problem and it is still there, with no estimated time for repair due to a shortage of replacement part. It was not inspected by the police or insurance. There weren't any warnings or symptoms prior to the failure. Hyundai has issued recalls for 2022-24 models for this problem but not the 2025, although it appears they have not fixed this for 2025 models.
