These Kia / Hyundai ICCU issues are annoying as we’d pretty much decided on a used 24/25 plate Ionic 5 as our next car. It’s a perfect used purchase as the warranty can be 5 years even on used models. I’ve read quite a bit and the latest info seems to suggest they have now completely redesigned the ICCU and have stopped supplying the old one. They’ve paused repairs until new units are ready.
