Consumer Description

I started getting the error Electric Vehicle System error in my month old Ioniq 5. After driving a few miles, the air conditioning stopped working completely. And after a few more miles, the vehicle started to throttle down the speed to 20-25mph that too on the I95 with a 65mph speed limit. Had to turn on the emergency lights and drive slowly till I reached my destination. After googling for a while, I found that this issue is related to the ICCU failure that is pretty common in the Ioniq 5 and Hyundai is yet to issue a permanent fix for this problem. I don’t know why we are allowing the sale of these vehicles with known issues. You can even Reddit the ICCU issue.
