Hey all! They called me yesterday and I picked up my 2022 Kia EV6 Wind today. Mission complete. Thoughts and good wishes for the rest of you. I'm in San Diego.

Just to follow-up and when I thought my regular interaction with Kia was over, I received an email from Kia corporate about a week ago, asking for receipts for receipts of car payments and gas for the loaner. Stay tuned.

9.5 weeks, but replaced and running great again....

Well… it’s my turn, apparently. My car stopped accepting Level 2 charging last Wednesday (4/2), though it was still drivable. I scheduled the first available service appointment for the following Monday (4/7). After three days of lackluster communication from my service advisor, they finally confirmed that the ICCU needs to be replaced and that it’s currently on order. No additional details or ETA for the part were provided.

For reference, here are the specs of my vehicle in case it helps others who might run into a similar issue:

• 2022 Wind RWD (built July 2022)
• Original owner, Southern California
• 34,000 miles
• Original 12V battery
• Neither software recall completed
• 95% of charging done via AC
• Emporia EVSE limited to 40 amps

In hindsight, there were a few red flags. I usually saw a charging rate of around 9.4 kW, but over the past couple of months, it had been fluctuating down to around 8.9 kW. Also, the amber light would frequently turn on with almost any action, even while the car and HV battery were off.

I have a 2023 Kia EV6 GT-AWD with 14,000 miles. The battery was dead and charged by dealership about six months ago. “Good as new” the dealership said.
Earlier this week on A 5-lane freeway, the car “died” and I almost caused a major crash pile-up trying to get to the shoulder. Towed it to the dealer and it’s the ICCU. it is globally back ordered and won’t be in for several months. At least it’s under warranty and Kia will reimburse for a long-term rental car. I’m wondering if the replacement ICCU is also defective or has the design flaw been fixed?

Had you got the latest recall done?

The amber light kicking on all of the time was something I noticed in the weeks leading up to my second ICCU failure as well; seemed like it was on very frequently and if I unlocked the car in the evening so I could plug it in, the amber light would kick right on. Since the ICCU replacement, I haven't seen the amber light at all. I'm sure it's been charging, just so infrequently that I haven't caught it.

ICCUs are starting to show up. Check state lemon laws if the dealer has the car for > 1 month to see if they apply or not.

I have been following the ICCU issue closely. So weird there is no real commonality for the failures. Newer and older, low and high milage cars get it. AC or DC charging get it. The only thing I noticed is that like you said, the orange light coming on frequently as well as 12V battery failure seems to be a common symptom before failure. Last December I noticed my orange light coming on more frequently. I changed out the factory battery and since then I have seen the orange light only 1 time. Hopefully I will not get the failure or if so after HMG confirms a new better design. Over at the Hyundai Ioniq forum some users who got replacement ICCU reported a different part number ending in QQH https://www.ioniqforum.com/threads/...rean-press.49161/page-20?post_id=633254&nested_view=1&sortby=oldest#post-633254 . Pure speculation if it is a redesigned part, HMG will most likely never confirm that for legal reasons. Also an engineer claims that he knows the exact cause of the failure. The link is somewhere in that post. Too technical for my understanding

Got a bit of runaround today and managed to open a case with Kia Consumer Affairs finally. We’ll see where this goes. They advised me as well that they do sometimes buy the cars back. Hopefully I at least get my last 4 payments back.

Talked to Kia’s Lease team initially and they only gave me an option to pay my 4 remaining payments now and hand them back the car. That’s the last resort option to at least save on insurance as I can’t imagine us driving this car any more.

If your case worker is anything like mine, they will lead you on with the Buyback (Lemon Law) and then tell you that they are "Unable" to make that offer.

Yeah my new ICCU is also 1XFA0QQK model number which someone elsewhere said is "the new one" for whatever that's worth. I would think maybe cold weather could play a role in failure rates, but one of mine failed in winter and the other in summer, and the failures aren't limited to cold-weather states by any means.

That's what I had hoped, too, but no such luck, unless QQK (for Kia vs. QQH for Hyundai) is it.

I didn't see it in that post. Maybe you meant this post:

I read an explanation about ICCU issues that made a lot of sense. It's a well known problem generally in electrical switching that moving from zero load to full load instantly can eventually cause failures. So in many applications they use a 'Star/Delta' switch where power is introduced in two phases with low power initially, followed by full power very soon afterwards. Such soft start systems are common in industry. The suggestion was that the software update was designed to introduce this type of system whenever the ICCU is engaged. That works in thousands of other applications and I see no reason why it would not work here. At least it would reduce stress each time the ICCU was energised.

or this post:

The 272 recall fixes what seems to be the root cause. Apparently, they finally found that the MOSFETs turning on instantly created a voltage spike that caused damage to the charging circuitry. As a retired industrial electrician, I find that to be perfectly plausible. Sudden switching on of high power circuits typically causes big spikes. I'm surprised they didn't anticipate that in the original design. The update, from what I've read, turns the MOSFETs on more slowly and avoids that voltage spike. If that's the only problem, then this is the fix.
I'm cautiously optimistic that the 272 recall will finally put this to bed.

So, no, it's not a waste of time. If you don't get the recall done, the ICCU will continue hammering its own circuitry till something burns out again.

That explanation is consistent with posts on this forum as well. The "272 recall" refers to NHTSA Part 573 Safety Recall Report 24V-868 for Hyundai which corresponds to NHTSA Part 573 Safety Recall Report 24V-867 for Kia who responded with Manufacturer Recall No.: 327 (SAFETY RECALL CAMPAIGN - ICCU AND FUSE INSPECTION/REPLACEMENT AND ICCU SOFTWARE UPGRADE).

It didn't prevent my ICCU from failing, but perhaps it already was too damaged.

SC302 was applied on 13 May 2024 at 5,732 miles
SC327 was applied on 2 Jan 2025 at 10,506 miles
Currently the odometer shows 11,988 miles

Hi Everyone,

For those who had recent ICCU failures, I'm Interested to see how long wait times have been for the ICCU replacement part in the USA.

Mine failed yesterday. The dealership said there are about 2,000 are on back order across all USA dealerships. No idea what that means in terms of wait time, so I figured I'd ask here.

Love the car, 2023 EV6 RWD w/ tech package.

I just got a call that the ICCU part that has been on backorder had a "quality control issue" so it was not shipped. It has been four and a half weeks, and now I am back at square one with a TBD date for the part to get to the dealership.

 

[bjmsam]

This post on Reddit is encouraging (emphasis mine):

Picked up my repaired EV6 today - ICCU replaced 19 days after my car was towed to the dealer (waaaay faster than I was expecting). It seems that - according to my dealer's service dept - the redesigned ICCU is now shipping in volume and the new unit appeared at their dock yesterday morning. ICCU, fuse, fluid and 12V battery replaced, all under warranty.

The service manager pointed out that ICCUs designated "QQK" after the part number (see repair order attached) are the new design. Drove it home from the dealer with no issues, fingers crossed the redesign will fix the problem. Wishing all of you with dead ICCUs a speedy recovery with a newly designed ICCU ...

 

[BoogieWoogieWoogie]

That's all good news, but the issue is that those of us with original ICCUs (never replaced with earlier model ones) have no idea the extent of the damage our ICCUs have experienced. Kia is then putting the burden on owners to just keep driving until there's a catastrophic failure, like on a 2000 mile road trip.

 

[BanditTA]

Dealer today 100% confirmed the ICCU was fried and advised about the global back order on ICCUs. He gave me a rough estimate of 6-8 weeks but warned me prior ones had taken over 4 months. I have a feeling I won’t see the car again before the lease ends. Dealer gave the info to Kia consumer affairs today too.

I have an insurance payment due on it in a week and am debating if I should wait for the case to be closed out or just pay the 4 payments. I guess I can see if there’s some bare minimum coverage I can get while it’s dead.

 

[dalillama]

Just to follow-up and when I thought my regular interaction with Kia was over, I received an email from Kia corporate about a week ago, asking for receipts for receipts of car payments and gas for the loaner. Stay tuned.

That's exactly the email (and voicemail) I received today from the manager working my case. Planning on putting all that info together tomorrow and sending it up so we'll see what happens.

I haven’t called yet, but my dealership gave me this number to call Kia directly in order to let them know my feelings: (800) 333-4542

After nothing but crickets all week, I finally heard back from our service adviser (I had to escalate to the service manager just to get an update). Replacement will be covered under warranty. The ICCU is on backorder with NO ETA provided, he mention it could be days, weeks, or months. I'm a bit relieved in the meantime since Kia has authorized a long term rental. I'll update as the process unfolds.
