Integrated Charging Control Unit (ICCU) failed while driving. Heard a pop from below the rear seats. "Check vehicle electrical system" message popped up initially, then changed to "Stop vehicle and check power supply" Vehicle could not exceed 20mph directly after failure, then lost all driving power just as I pulled the vehicle off the…
Car's ICCU blew as I was pulling out of my driveway. Was able to limp to the dealer. They replaced the ICCU in a week
Driving under normal conditions, heard a “pop” near the rear of the car and within seconds had an immediate loss of power. The dashboard had lit up with “Check electric vehicle system” and was limited to 20 MPH on a 45 MPH road with no safe place to stop. Was able to limp car home, dealer confirmed ICCU was faulty and had to be replaced.
I have experienced two high voltage battery failures both requiring hv battery replacement. The first occurred around 6000 miles and the second occurred around 13,000 miles. I also had several dead 12v battery episodes where the card would be dead; even when plugged into the home charger overnight.
What happened to me is a common problem with these models. I had an issue with the 12 V battery not being charged by the main battery as it should be. This led to a blowing of the main fuse which took out the ICCU unit. This seems to be fairly prevalent from what I can tell from online forums, and there needs to be a recall from Hyundai
