Some members will remember that I had issues with charging my EV3 which I collected in December. The car is currently in the garage and I have a courtesy car to give them a chance to resolve it. Having tried charging on other chargers away from home (both fast charge on DC and slower charges on 7 kw, 22kw using AC) I have been able to confirm to the garage that when fast charging there is no problem, but anything using the AC port causes issues. E.g. on a 22kw it was only charging at 3.4 kw, on a 42 kw AC only it was charging at 10.3 kw. I have saved all of the screenshots from the App and provided them. I am also now charging the replacement courtesy car on my home charger with no issues. Just wonder if anyone else has had this issue since I last posted? Thanks in advance

The software update did not fix my ICCU. I have seen it suggested that the update may prevent or reduce the risk of ICCU failure, but once the ICCU is damaged the new software will not fix it.
I would love to know what the new software does to prevent or reduce risk of damage to ICCU ? Is it temperature controlling or reduced voltage? Certainly for me the home charger still appears to delivering normal power at 100% since update I do however have no confidence that this ‘potential problem’ will not occur sometime. Every time I charge over night I expect a problem in the morning !!
I don’t ‘expect’ a problem after home charging, but I certainly ‘fear’ it. To the extent that if I need the car for something important, I won’t leave charging until the night before. I will instead charge up the day before that, so that if there should be a problem, I have a whole day to find a solution or workaround.
Which I’ll be honest, is far from ideal

I have no information from Kis on what updates include. I have seen suggestions that it reduces level of transients under some conditions and/or reduces risk of over temperature. But just my recolection of 3rd party reports. Someone like @mateybloke might know more.
I suspect and hope that a dealer update would also include some testing, but cannot see that taking very long, unless the update followed a problem that needed time to verify it was fixed. That said I have often had the dealer say they need the car for the day and found that they did not even start work until mid to late afternoon. On one occasion they left it so late they could not finished and kept the car for another day. On another occasion booked a while you wait minor service only to be told, on arrival, that there was a safety recall and they needed the car for the day. Left my car for an MoT on my way to work, when I arrived back at 5:30 they had not even started. To be clear this covers all makes and models over the years. Not seen any evidence of difference between dealerships.
The only information we ever had on this was from the Kia EV6 recall in the US and all of the safety documents that came with that.
EV3 ICCU is a different model so i can’t say for sure what was changed.
Only thing i noticed was that the cooling system seems to come on more often whilst AC charging and the front vents also seem to open more often.
Also V2L can handle my power tools like the EV6 could. The EV3 could not do this before the update.

Update on fix, I took my car to the dealer for the ICCU update, after testig there it did not fix the problem so will now wait 2 weeks for car to be booked in for ICCU replacement. It has now taken 4months since the problem occurred, disappointing with how this is going,my dealer blames Kia on delays.
I am still waiting for a replacement ICCU to arrive on back order.

Yes I am booked in to get a new ICCU in my EV3 to solve this - there was a 6 week wait though given that this is a widespread problem.

As you know they are franchises & Will not be getting paid much for the work.
Even getting services booked in has to be done weeks in advance. I guess they have cut staff down & simply do not want to employ more, so long delays are the norm.
I have the reducing consumption ICCU problem. i.e. it drops to 1.6 KWh charging or whatever it is. I've been AC charging (at home on a 7.2 Kw) successfully for several weeks now having set the car to only take 90% of the max rate(ie approx 6.5 KWh). I have the car booked in for a diagnostic but it is several weeks away.
I'm retired and don't do that many miles and rarely do I have to be somewhere urgently.
Given the number of issues with ICCU I'm beginning to wonder whether I might just stick with what I have rather than get a replacement ICCU in however many weeks/months it might take. Better the devil you know.
I'm slightly concerned that if I don't report a known error that it might somehow affect my warranty in the future in some way.
Thoughts? On sticking and warranty point.

No, get it replaced as soon as you can.
As you can be sure that at some point it will stop working & it will be when you need it the most & dealer will not have any in stock.

Mine is due to be replaced in 2 weeks.
I'll stick with charging at 90% after that.
I'll stick with charging at 90% after that.
The only problem I can see with sticking with 90% charging, once the ICCU is replaced, is that you may mask a future fault, which could subsequently result in total failure in the future.
Once replaced, I intend to fully test the new ICCU to be sure that I have "a good one".

I was planning to leave it a couple of months until a few others been guinea pigs, but I take your point.
Usually I would agree that it is better to let others test things like updates before installing them. However in this case, it is by no means certain that Kia have solved the ICCU problem and if I am given another "fault prone" ICCU, I would rather know sooner rather than later. 90% charge rate is a good "keep you going bodge" if you run into more problems but is not a solution.

By the time you get it, some will have been. But when some users are on more than one replacement. Could the issue be somewhere else in the wiring?
