I have ICCU (integrated charging control unit) failure seems to be happening on early ionic 5 models
Mine failed last week on my 2021 EV6
Interested to know symptoms that led to failure. I can charge at DC fast charge but not at home AC charge.

Purchased my EV6 in mid April 2022. Currently about 11,000 miles. At about April 17th I got warning lights and had to turtle home. Fortunately, it happened a few blocks away and I only live about a mile from a service center.

Since about November I have had issues with the android auto going in and out. It's annoying and I never really wanted to deal with it because I didn't want the cat to disappear with the dealer for a month. Another odd thing that we and my wife noticed is the wireless charger. Hey phone can wireless charge and mine can't but we both will normally put our phones at that location when driving. We both were getting warnings about our phones overheating and I'm not sure if it's because they were partly in the sun or if it had something to do with the wireless charger.

Early on we had a trunk latch issue which I only bring up because at the time they told us that the party had to come from Korea. We were dealing with KIA VIP customer service and the dealership and were getting two different stories on tinder frame. KIA was saying that the part was on a boat with arrival TBD. Somehow the car was finished in about a week. Not sure what happened to make that happen.

I charge mostly at home with a 9.6 kwh charger.

When this happened I was messing with the v2l settings while at a traffic light. Then 20 seconds later the warning light came on.

No other warning or symptoms of a problem. I really like the car and driving a ice rental really makes me miss the car more. Then again I'm thinking of just an e-bike to do local traveling. I love my metal box on wheels but a good cargo e-bike will suffice and be better than the crappy rental.

@Iliveinapark So did you have an ICCU replaced?

I'm waiting on a new one as of today. They said it could be 3 days or month. Part is coming from Korea. I assume via boat. They made it sound like if they had the replacement than it would take a day of work. They said the battery was fine.

@Iliveinapark same here i suspect we'll be seeing a lot more go “puff “ over the next year or so.

Hers what i don't understand while my car according to kia has the ICCU problem it drives perfectly able to DC charge it has no warning lights the 12v gets topped up while driving and even over night the main battery kicked it to charge the 12v battery when it went down to 12.1v

I'm just glad they handled it same day. I'm thinking between the ev6 issues ioniq 5 problems that the iccu will be a quiet recall. KIA has too many problems right now to dive into computer issues. I'm just hoping this is the only issue. Like others have said... The warranty is great but without the car does it really matter? Idk either way I'm getting the bike crusade. Mo car mo problems.

Hey, I'm in ireland , had the issue in January this year with my GT line - 34k on the clock - car woulnd't charge on AC : it would start charging at 1kw then stop. DC charging worked fine. I connected the V2L module and heard a popping sound (like a blown fuse / capacitor) - car would still start in limp mode - it completely broke down as they were driving it onto the tow truck. Took 7 weeks to get parts. Bad experience all over and not a feck given by Kia Ireland customer care.

I haven't had it confirmed yet, but I bet anything that that's what it is. Drove my new GT off the lot on the 28th and went to try to charge it two days later and it wouldn't work on any LV2 charger. Kinda getting the run around with the dealer and techline, but they are still trying to go through the steps to determine the issue. I just hope this gets resolved soon, but it sounds like it will be awhile. There's only one DC charger in town and 1/2 the time it's not working :/

Bought my EV6 in August 2022 and this happened to me March 29. The car is STILL at the dealer waiting for this part to come from Korea. There's no ETA even from Kia Customer Care Center.

What happened: I was taking my daughter to school one morning, heard a strange loud clunk under the rear seat, then got ominous warnings on the dashboard to "Check electric vehicle system" and then "Stop vehicle and check power supply". Then the power dropped to max of 25 mph. Luckily, I was close to home and limped it home. Then it wouldn't move, so had to have the car towed via Kia Roadside Assistance to the dealership.

Took several weeks before the dealer even looked at it to diagnose the problem (staffing issues), and I had to keep checking in on them. They finally diagnosed as failed ICCU and ordered it from KIA. It's been on backorder since 4/19. They flagged it as "expedited" the next day. Kia Customer Care says there are 87 of these parts on backorder in the US and they have no idea when they'll arrive. They have to be manufactured, rather than just pulled from a warehouse. WTF.

Loved the car until this, now not so in love. Back to my old gas powered cars now.

ICCU failures are sounding more and more like a serious issue, especially if it occurs on the highway and your speed suddenly drops to 25mph.

Has anyone that's experienced the blown fuse/ICCU failure reported this to the NHTSA?

That's a good point. In my case, we were on a more of a neighborhood road, but I did put on my hazard lights, because I wasn't able to keep up with the flow of traffic.

I filed a complaint today with the NHTSA.

It just happened to me today, shortly after I start driving the car "Check electric vehicle system" popped up together with a 12V battery red logo on the dash, followed by "Stop vehicle and check power supply". I pulled back in the parking lot and called the Kia dealership, but it was after 5 PM and they were closed for the day. I opened Kia connect and they apparently only tow to the closest dealer which unfortunately is not the shop I normally take the car to. I left the car there until tomorrow morning when I will call my preferred shop and see if we can get it towed to them instead.

I have one of these USB cigarette adapters that show the battery voltage. It would read a little over 14V normally but now it was showing 11.9 V. I suspect that the ICCU has failed, and the car was only receiving 12V from the flooded acid battery. Previously in the day the car was charging using a L2 7KW charger. It kind of ruined my plans for the evening and I had to call my wife to pick me up but at least is parked in a secure area. Will see how long it would take to get the part, I will post my experience here.

10,700 miles, 13 months ownership.

Sorry to hear that. I wouldn't wish this hassle on anybody. Did yours go into reduced power mode like mine and others? Maybe you didn't drive enough to find out. Might be worth taking it for a spin around the block to see what happens before towing to the dealership. If you do get confirmation it's the ICCU, you can help us all out by reporting to the NHTSA as a safety issue. If enough folks report it, it might force a recall to get the issue resolved before someone gets hurt.

I think it did, I drove on the road near-by a few miles but that road has a 25 mph limit and I was not driving very fast. At that point I saw the 12V battery dropping and I knew I don't have much time before is going to shut down and leave me stranded in traffic. My main focus was to get back in the parking lot and to call my wife to ask her to go and pick up our kid from school. I suspect that when the second message "Stop vehicle and check power supply" shows up your speed is limited. It was a few minutes after the first warning.

I will report it to NTHSA for sure today. If the repair takes more than 30 days I will pursue all legal options. I don't care if I lose money, someone will need to stand up. I really like my car but at this point I find it unreliable comparing with my previous cars I purchased new.

I was reading Kia Roadside assistance terms and it appears they only cover $75, I'm wondering if I should use the Roadside assistance provided by the car insurance which covers "All reasonable costs" instead.

Crap, sorry to hear that. This makes me really nervous because I'm right behind you in months of ownership. I'm at 16xxx km and it has been almost a year.

Waiting for it to happen is the worst part. I'm shocked Kia isn't stocking ICCUs for when it does happen. Waiting for the parts to be available is the second worst part.

And the fact that it just occurs out of the blue is really annoying. No warnings.

If you haven't already, please fill out the spreadsheet tracker so we keep a record of all these failures.

Edit: here is the tracker KIA EV6 ICCU

Short of Kia issuing a recall the only thing you can do is to have a decent roadside assistance service. In the US Kia assistance only covers $75 towards towing costs. That does not go very far.
In my case I used the insurance roadside assistance that only covers 20 miles, I had to pay $150 to have it towed 60 miles away to my preferred dealership that will be able to diagnose the car today and hopefully order the ICCU. The other dealer that was closer could not look at it and diagnose it for 3 weeks.

Another update, the car arrived at the dealership and the diagnosis is that the ICCU failed. The bad news is that the part is backordered and Kia also needs to approve the part, that would probably add a few more days on top of the already long wait time.

I don't feel that bad about it, at the end of the day a car is just a tool that takes one from point a to point b. Is not part of the family or even a pet, just a car. A really nice one that sits lonely in a parking lot now while I'm driving around in my high mileage 10 years old car. They offered a rental which I declined for now.

There is also the fuse as well and possibly a solenoid. Make sure they get at least the fuse along with the ICCU otherwise it won't work.

Yea you're right, it's just a car, I just don't like the hassle. Such are the risks of early adopters

You know how it goes, there is so much I can tell them about how to do their job. They have technical procedures they need to follow, basically they told me there is 0 volts coming out of the ICCU to charge the 12V battery and that they need to open a Techline with Kia. They also said Kia is pretty responsive to such requests and they might provide additional recommendations, however there is a backlog on getting ICCUs. I told them that I'm worried about the 12V battery losing charge and that it would be great if they can charge it and then disconnect it or it's going to die a slow death due to surfactation if it loses charge. They are waiting to hear back from Kia about ICCU replacement approval. At this point I'm 50-50% if I should keep the car after this is over. The main battery is at 90% charge and probably is going to stay there for a long while. I don't expect the main fuse to be blown because the car can still be driven, we were able to drive it on and off of the flatbed.
