I’m looking at buying a 2024 GT-Line and was wondering if I can assume a new car will have the necessary software fixes in place. Is the software update just a temporary fix, or should I still be worried about the car suddenly stopping on the highway? Should I be looking for the latest VIN number to ensure any changes have been made to address this issue?
Someone on this forum with a 2025 model had the ICCU issue. It seems like Hyundai and Kia share some of the same parts, so even a new Kia might have the same issue. I was planning on switching from the Ioniq 5 to the EV6, but after reading posts here, it looks like I’ll just be dealing with the same frustrations.
@Frey
Are you talking about Kai Cenat?
Maybe yes, maybe not. It’s said that only 1% of vehicles are affected. I bought a 2023 model on Boxing Day and had to take it to the dealership for ICCU issues with only 9755 km. Mileage might vary. You can check the VIN on Kia’s site for open recalls, but if the car didn’t show ICCU errors when it was brought in, it likely just got the software updates and not a physical replacement.

Shouldn’t it be ‘kilometerage’?

Did the patch just slow down the charging speed?

I don’t know. I only had the car for a month and it came with all the patches.
Knowing Kia, it’s possible. The issue affects most 2022-2023 EV6 models made from November 2021 to February 2024. Some 2024 models might also be affected. I don’t think the software update really fixes the issue long-term—it just delays the inevitable. The 2025 model has a new ICCU part number, but no details were released on the changes.

I guess just take care of it until it’s out of warranty?

I’d rather have the issue under warranty so it’s covered. Once the warranty is over, I’d treat it with care but for now, I’m going all in.
@Lennox
I think what he’s saying is that Kia/Hyundai just patch things up until the warranty ends, then you’re on your own.
@Lennox
Exactly, they just want you to ‘baby it’ until it’s out of warranty.

Kia extended the warranty to 10 years here, so that’s not a concern anymore.

Babying it won’t fix the ICCU issue. You still have to wait for a replacement part when the dealership gets them.
There’s no real way to know for sure. Some people with 2022 models haven’t had the problem. I have a 2022 first edition and had the issue immediately. It took them 3 months to figure it out, but I haven’t had a problem since then.
@Fallon
So, what did they do? Replace the ICCU fuse and update the software?

At the time, there were no software patches. The car had only been out for two days in the US. In the end, they replaced the ICCU and the fuse. They even flew an engineer from HQ to figure it out, pulling parts from other cars until they figured out which ones were causing the issue.
Thanks for the replies. According to the recall, all cars made after February 2024 should have had the software fix. The cars I’m looking at have been on the lot for under 90 days, so they should have had the update. For long-term peace of mind, at least the warranty is long. We had a 2021 Kia Niro EV, and that had a 1-2% chance of the gear reduction unit failing, typically after the warranty expired.
@Mika
I bought my 2024 in November, registered in July. I still had to take it in for the recall in December for the ICCU, and got the software patch. No problems yet, but it’s only been about 3 months.
I’ve had my 2024 EV6 for a year, about 8000 miles, and haven’t had any issues. I’ve brought it in for two recalls though. I’m hoping I won’t face the ICCU problem but I’m prepared if it happens.
