I have the same issue, I just dropped my vehicle this AM for the 3rd time for this issue.
They already replaced an EPUMP, and its been fine for a couple of weeks but this last Friday the issues shoed up again. Dealer says when they plug the computer in there are no codes register for anything. Lets see what they say now.
Also first time they received the vehicle they said the levels on the reservoir where good and they went ahead and drained a little and refilled it just in case but that didn't do anything.
Second time they received it they send videos and pictures to KIA to share what was going on, and that's when KIA instructed them to replace the pump. Wanted 3.5 weeks since the part was on back order.
Lets see what they say now.
