Should I buy the Kia EV3 or.../ “What is known about the problem?”

I have been a satisfied driver for 5 years now and follow you constantly on LinkedIn. I will soon need to return my highly reliable 2021 Hyundai Kona 64kW to the dealer. I decided to replace it with a KIA EV3 Earth 58/81kW. There are no doubts about the quality and performance of this car. But I’m a bit worried about the well-known issue with the ICCU. It’s true that the problem mainly affects 800V platforms, but from what I’ve read, even 400V systems aren’t completely immune. I’ve been gathering information online for days. There’s no talk of a permanently resolved issue, just software updates and extended warranties. As people who are more familiar with this topic, do you have any more specific information? Is KIA planning a model refresh in 2027 with a completely redesigned ICCU? Maybe I’m asking too much, but...

Here is what happened and what the current situation is

Answer. The ICCU (Integrated Charging Control Unit) is the core of the electrical system. Its primary task is to manage the flow of energy from the high-voltage battery to the 12V battery, as well as regulating external charging. When this component fails, the car loses its ability to recharge. In worst cases, it may stop suddenly while driving. After several reported issues, the Hyundai-Kia group stepped in and appears to have resolved the problem, which caused significant inconvenience. They extended the warranty on this component to 15 years in some models, thus covering any potential issues for almost the entire vehicle’s lifespan. As for the EV3, a thousand units have already been sold in Italy by 2026, with excellent feedback, and no ICCU charging problems have been reported to us.
