do these still have the ICCU issues?

They still use the same ICCU as the Ioniq 5 & KIA EV6 and all EGMP cars only software updates have been applied and the ICCU warranty extended to 15 years. Hyundai refuse to acknowledge the issue or even take responsibility for the issue other than extend the warranty. There have been 5 recalls for updates #272 is the latest and applies to all EGMP cars including Ioniq 6 N. The issue is when it goes the car is dead and needs to be recovered and then you join the wait list for a replacement. My friend waited 3 months to get his 6 month old Ioniq 5 N repaired.

TBH it’s a bit like the RROD on Xbox.

Still love mine though. lol

I've also known a few people to have theirs replaced with a turnaround of weeks. Worth noting that if you do have the issue, getting it recovered rather than driving it in is the better option as you will get a courtesy car from Hyundai (and everyone I know that's had the issue has had a 5N as the loan car). I've seen a few people drive it in, and it becomes up to the garage to offer the courtesy car at that point.

Hyundai/Kia claim the failure rate is less than 1% independent investigations show it around 25% there are a few high level legal cases in the US and one in Germany that are in progress regarding it. You only need to look at the owners forums to see how bad it really is. Most uk dealers the ICCU is on back order from Korea with up to a 90 day lead time.

If it fails you loose all charging of the 12v battery driving it could result in sudden power loss and is really not recommended.

Would love to see the sources evidencing 25%

I’m part of many 5N/6N owners clubs and none are anywhere close to that percentage and there have been a few polls (I believe issues will be worse on earlier models prior to the EV6 GT/5N due to changes in hardware and software)

When it happens the first thing you likely notice is the lack of charging the main battery or a pop noise followed by limp mode and you generally have a lot of time until the 12v is too flat and the car becomes unresponsive. As the car goes into limp mode I’ve seen many people say they drive it to a local dealer then had issues getting a car, hence the recommendation of getting it recovered.

They don’t just cut out unless you’ve ignored the warnings etc (or been unlucky and it failed whilst you’ve left it alone for a long time on continuous charge).

The N/GT models are a very small percentage I know two that have had issues both needing the ICCU replaced (One being mine). If you look on the Ioniq 5 and EV6 owners clubs on Facebook both have pols showing worldwide users that have had issues. There are thousands of them. It affects all EGMP platform cars they all use the same ICCU.

I have had it fail and they do just cut out. Mine went pop on the M6 in my Ioniq 5 it made it just under a mile then was completely dead I had it recovered to Hyundai who by chance had an ICCU they had ordered for another customer who had decided to refund her car. I was told if not it would have been on order from Korea as dealers do not stock them. There was no warning before hand and it charged fine the previous evening.

My EV6 GT had the ICCU replaced at 12 months old and recently had the 12v battery replaced as that also died. It now has the latest software which greatly reduces the chance of failure but does not prevent it. My friends 5N also went sudden and required recovery which I remember him saying was a pain with two kids and two German shepards in the car.

It’s just one of them things I have accepted and don’t worry about.

A quick ai search brings up this -

A national class-action lawsuit filed against Hyundai Kefico Inc. alleges that defective Integrated Charging Control Units (ICCUs) in certain Hyundai, Kia, and Genesis electric vehicles can cause sudden power loss and battery failure. [1, 2]

Key Details of the Lawsuit
    • Filing: Brought by plaintiffs Hayes Young and Roy A. Williams in the U.S. District Court for the District of New Jersey. [1]
    • Core Allegation: Hyundai failed to disclose that the ICCU—which manages power flow between the high-voltage and 12-volt accessory batteries—is prone to failure due to fuse and transistor stress. [1, 2, 3]
    • Recall Context: Despite previous software and hardware recall campaigns by Hyundai to fix or replace faulty units, the lawsuit claims that replacement ICCUs can also fail and leave vehicles vulnerable to sudden shutdowns or dead 12V batteries. [1, 2]
    • Warranty Extension: In response to widespread issues, Hyundai extended its US ICCU warranty coverage to 15 years or 180,000 miles. [1, 2]

Fitted a hat to my Ohme might last a bit longer or not. Lol

@MOOGLEYS Where did you get that? If nothing else it will keep the snow off it when it arrives.

Nissan must have absolutely useless coders. For the past two to three weeks Nissan Connect was at first on limited useability and then nothing at all from last week. They are relaunching the app with a new design and it was supposed to have launched last Friday at 16.00. That got put back to 12.00 on Saturday then 16.00. Then they set back again to Sunday at 16.00 and got set back again to today at 16.00. Now it's been set back until Friday 4th September at 20.00. I am sure I have missed one or two further delays in that lot. As the OHME app uses the Nissan Connect app to pair the car I now know why the charger hasn't paired with the car for the past three weeks. I have to tell the charger what percentage the battery is on and how much I want it to charge to but as it doesn't know what car and what size battery I have it always overcharges past what percentage I want it to stop at. It's not even the same percentage each time. Say I set it to charge to 80% most times it will stop at 87% but I have had 78%, 83% and even 99%. I am sure it's something to do with Octopus alloting 10 minutes here and 10 minutes there, since this six hours came in the charge times are all over the place and never at full power. They have made it far too complicated.
