Consumer Description

The vehicle popped up a screen that said check power source. Then within 30 seconds went into limp mode said power was limited and couldn't drive faster the. 25mph in the middle of a highway. By the time I pulled over to the side of the road my car was dead. Ive been trying to get Hyundai and the dealership to dignose the issue. Based on the error codes I was given it appears to be a dead iccu and 12v battery. I am in a ioniq group on Facebook and over the last week of being in it I've counted over 50 dead iccu on this group alone. All in one week.
