Consumer Description

ICCU failure. Car was dropped off with Kia and the (second) recall they claimed to have performed did not fix the 12-v battery charging system error. They ordered in a new part, which was on national backorder and they provided no ETA. I had to purchase a replacement vehicle after 30 days of them having the vehicle without making the repair, providing an update, or having given me a loaner. Received message it was fixed after 37 days, but no information whether it is with a new part. Subreddit for the EV6 shows this is a widespread issue that has not been permanently resolved. When the ICCU fails, you are limited to 25mph "limp mode" and will lose ability to move car if 12V battery dies.
