Hyundai Ioniq EV’s have a continuing issue with a component called that ‘ICCU’. The ICCU and high voltage fuse failed even after two recalls meant to monitor that problem and update the software. Luckily, mine failed in my driveway at home which did not put me in immediate risk. However, many people have this part fail while driving on roads and highways with zero warning. There have been two ICCU-related recalls that my car has had. When I started my vehicle I heard a ‘pop’ and then the dashboard said ‘Check vehicle electrical system’ and then shows the ‘limp mode’ icon allowing to drive the vehicle at a slow speed to safety.
