The issue was last fixed in November with a software update. Whatever it was doing was overheating the ICCU and blowing the fuse for the 12V battery charging system. Apparently they do the software update and check for the OBD2 code. If it is there, they replace the ICCU hardware even if the fuse has never blown. Mine came with the updated code, and has never been a problem. Is it really fixed? Hyundai seems to think so. Haven’t really heard complaints about this one in a while, so at the very least it seems the update has lowered the incidence rate.
