Yes, both EV6 and I read somewhere that GV60 are affected by the same issue. However, is just starting up since they were a few months late to market after Ioniq5. My dealer was not surprised, and they diagnosed the issue very quickly (less than one hour) this makes me think my EV6 is not the first one they saw with this issue. I should ask if they have other cars in the parking lot waiting for parts.
ICCU Failure
How many members have had an ICCU fail?

Currently 32A is fine and I am not sure if temperature goes up during the summer, I might go down more. I have not update new TSB. The reason is…. New TSB will lower the speed and it might go really slow speed but unfortunately, if the connector is cool down, it will not speed up. I prefer steady 7kw instead of 9kw for one hour then low speed for rest of charging session. I will keep monitoring….Some have charging port temperature sensors failed.... If after TSB is still happening you should get to service department and ask them to test for overheating while charging at 48A.
I will be looking...if you have carscanner app....you can record and make graph for charging port temperature sensor.Currently 32A is fine and I am not sure if temperature goes up during the summer, I might go down more.

I have replaced so far 14 EV charging ports.....none of them have come back or complain after repair. For non experienced EV technician or someone who is not familiar this is not easy to troubleshoot.
Having followed your Kia link and read the posts there do seem to be a number of EV6 ICCU failures.Kia EV6 owner here, my car ICCU died yesterday. I don't think it blew any fuse because I was able to still drive the car but the 12V battery stopped charging. The dealer confirmed that the ICCU has 0 V output. There are a few treads on the Kia EV6 forums as well. My car has a little over 10k miles and is about 13 months old. I've been told the ICCUs are on back-order (probably due to high failure rate, I would assume). I saw in previous posts some folks were wondering if battery preconditioning update could be a factor. My car does not have the update installed yet since it has been released to EV6 just recently and I had no chance to schedule the update yet. There was a TSB for charging interrupted that improved the charging logic and that has been installed a few months ago.
(90) Anybody have ICCU failure | Kia EV6 Forum (kiaevforums.com)
When I started this thread I mentioned that I expected EV6 & GV60 owners to be effected as well. Still no idea of the numbers involved!
I'm not sure about the numbers either but I'm reading the Kia forum daily and there are not many posts about ICCU failures, maybe a handful. Some have had issues charging using AC power, others have had the 12V battery dying. A few experienced the limp mode like I did. I understand any car can have issues, now the ball is in their court, if they can fix it in about a month, I'm a happy customer. If not, I might have to switch brands to someone that treats the customers better. The dealer is great, no complaints there, they got me in the same day and diagnosed the car, now KIA has to approve the ICCU replacement.Having followed your Kia link and read the posts there do seem to be a number of EV6 ICCU failures.

Then I have zero chance since my local dealership does not have good EV technicians haha.I will be looking...if you have carscanner app....you can record and make graph for charging port temperature sensor.

I am not comfortable to teach Hyundai tech person since I am not a technician.
Battery preconditioning update was huge issues and I had to explain everything in order to do correctly but can’t blame tech person because huge misinformation for TSB instruction too.
I have a question. If sensor is bad, does it matter with TSB update?
TSB update is just lowering speed so it will not get hot so you will replace the sensor with a car which update TSB and still have the issue? Or you will replace the sensor without TSB update?
TSB is for more optimized side to control overheating and lowering max current if necessary....instead of stopping session....if after TSB or troubleshooting sensor is still sending erratic signals ( this has to be tested by tech)....charging port will need to be replaced....there are procedures how to test it.Then I have zero chance since my local dealership does not have good EV technicians haha.

@HKtech - Has there been a new part number for ICCU? ie. a redesign?
364011XAB0. That is the part no. I had fitted as a replacement for 364011XAAO.@HKtech - Has there been a new part number for ICCU? ie. a redesign?
Sure wish Hyundai would step up with some information! What's the diff from XAAO to XABO? New ICCU exterior paint color? A fix for the Korean market coolant leak? Or did they figure out why the NA/European cars are failing?364011XAB0. That is the part no. I had fitted as a replacement for 364011XAAO.

To all EV6 owners visiting this thread. Please do NOT take a poll. You are not a random slice of car owners. You came there because of recent ICCU failure, therefore you make poll not representative.
Are only EV 6 owners with ICCU failure visiting this thread?To all EV6 owners visiting this thread. Please do NOT take a poll. You are not a random slice of car owners. You came there because of recent ICCU failure, therefore you make poll not representative.
When I started this thread and poll I was endeavouring to find out how many ICCU failures there were across all effected models, Ioniq 5, EV 6 & GV60. So if anyone has experienced a failure why can't they let us all know?
EV6 and GV60 are the same platform cars. Failure data is relivantTo all EV6 owners visiting this thread. Please do NOT take a poll. You are not a random slice of car owners. You came there because of recent ICCU failure, therefore you make poll not representative.
Well, Yaric is saying that there will be a disproportionate amount of EV6 owners who have failures coming here. Those who are doing fine aren't going to come take the poll, so there's a potential for skewing of the results.
Exactly. If we want to have relevant data about number of ICCU failures and at the same time keep proportion, I propose to add into poll another optionWell, Yaric is saying that there will be a disproportionate amount of EV6 owners who have failures coming here.

-Yes, I had ICCU fault (NOT IONIQ 5 model)
To be fair there was a lot less to go wrong and a lot less features with a pintoToo funny. My very first car was a 1972 Pinto and it was free of any issues the entire 9 years I owned it. 50 years later I buy 2022 Ioniq5 and about 54 weeks after taking ownership, I get slammed with the ICCU issue. It's been at the dealership for more than a month now with no news on when the parts will be in.
There are not very many EV6 with ICCU issues on the Kia forum, maybe a handful mine included.
Certainly. And on the other hand, I would not accept any No, I've never had an ICCU failure vote from anyone whose car has not been on the road for at least one full year. Even with reasonable constraints such as these, however, it seems unlikely that you would ever obtain an unbiased accurately representative result from the small subset of owners who read this forum and are concerned about this issue. Still, I suppose some information is better than none at all, as long as you can keep some perspective about its unreliabiity.Well, Yaric is saying that there will be a disproportionate amount of EV6 owners who have failures coming here.

Obviously Hyundai knows the exact answer to this question, and likely we will never learn it because they don't want to risk their reputation over it. Probably the only pro-active thing we can do (besides filing an NHTSA complaint if you've been bitten yourself) is to keep the issue as visible as possible through discussions like this to increase their motivation to fix it. If the occasional statistically unsound poll here furthers that goal, I'm all for it.
