On January 31, 2025, my 2022 Hyundai Ioniq 5 experienced a failure with its ICCU resulting in the vehicle to lose all power and become unable to be turned on exposing myself and others to conditions where the vehicle could become a serious safety hazard due to its complete lack of power. This occurred despite the application of the NHTSA Hyundai Recall 272 only two weeks prior to this incident which was supposed to prevent this serious safety defect from occurring. The vehicle’s 12 V battery was subsequently replaced allowing the vehicle to display a ‘Check electric vehicle system’ warning. The dealership has since confirmed this as the ICCU defect. No warnings or other messages preceded this incident.
