Help with ICCU update... should I go ahead?

Got this message today, not sure if I should proceed with the update. My 12v charges fine and I haven’t noticed any issues. Anyone with experience with the EV6, what do you think?

Just go ahead and get the update. No one is an expert here.

Seems like Kia isn’t an expert either, haha.

If you’ve got the notice and don’t do the update, I’m not sure if they’ll be responsible if it fails later. But if you get it done and it still fails, you’ve done what you can, and it’s on them. I might be wrong, but that’s how I see it.

If your ICCU hasn’t failed yet, it’s just a quick software update to prevent future issues. You should get it done.

I’d recommend getting it done to just move on. I booked an appointment right after getting my '24 Wind AWD. It took about two hours, they did the update, and checked the ICCU, which was fine. You could also ask if they have an ICCU in stock, they may help you avoid waiting for weeks, depending on the dealership.

Get it done. It’s clearly an ongoing issue with these cars.

I received the message today too. My appointment is on the 7th.

Just so you know, it seems that the update can sometimes reveal a bad battery. It happened to me and others. If the battery charges abnormally 10 times, the car just stops charging it without warning. So after the update, your car could die, but if you have a charger, you can charge the 12v for a bit longer. Make sure the dealer tests the battery, that might help catch any issues early. A new battery solved my issue. It’s been fine for 6 months now.

I posted about this before. After getting the update, the car was fine for three weeks, but then while driving 70mph, the ICCU failed and the speed dropped from 70mph to 20mph in a few seconds. I was lucky I wasn’t hurt. Definitely get it sorted.

I’m just waiting for mine to fail. I don’t want to be without my car for weeks while waiting for parts. Everything’s fine now, but I’ve heard that the update sometimes makes things worse.

After the recall, mine drained the 12v battery. It took a week for the engineers to confirm the warranty and replace the battery. The loaner car gave me a taste of what I’d be missing without the tech features.

@Vesper
You don’t really need tech for good seats or a decent radio. I chose the Wind because I didn’t want glass over my head.

I agree, especially after dealing with skin cancer.

@Jo
That’s the issue. If they find a fault code, they’ll need parts, but they won’t know until they check it. Doesn’t need to break for them to replace the ICCU.

If you’ve got the fault code, it’s almost certain to fail. It’s better to get it fixed.

It’s just an inspection and software update. You should be in and out of the service center in an hour or two. I already had mine done.

@Noelani
Yeah, I just had it done last week. It only took about 45 minutes.

That’s not the best logic. When it fails, you’ll be waiting on parts. If you take it in while it’s still working, they might be able to fix it while you have your car. You can just take the car back and bring it in later when the part arrives.

So it’s not just me.
