From what I’ve been reading they are now at a failure rate that’s massively lower than originally found. The main issue, however, wasn’t the ICCU failure but the massive delays in getting a replacement. There were cases where it was up to 9 months without your car and one poor soul was without his car for nearly 18 months after the replacement failed in the test charge. It was also a daily occurrence that the Ioniq 5 groups had someone complaining that their car had gone in for the dreaded failure, I’ve not seen such a post in months AND I’ve never had a problem with mine.
If one fails, it appears it’ll be replaced in weeks not months. So, while not ideal, there is the reassurance that the problems are greatly reduced and replacement times are even more reduced. I don’t think I’d be too worried about it now, there’s a chance that whatever car you get could just be the unlucky one.
