A Dealer Is Proactively Scanning for ICCU Failures - and a First Hint on the Revised Units

Interesting post on one of the Kia EV6 Facebook groups today. An owner reported that their dealership is now proactively scanning any E-GMP vehicle that comes in for maintenance work. In this case the dealer found a code stored that they said signaled a pending failure, and pre-emptively replaced the ICCU with a unit manufactured in April 2026. The owner spoke with the service advisor, who claimed that none of their recently replaced ICCU units are coming back in with subsequent ICCU failures.

It’s purely anecdotal, and it’s only one data point, but it’s a first answer to the most important question I’ve had since we learned there were new ICCU part numbers: are the post-January-2026 ICCU units failing yet?

Here are the specifics from the owner’s account and the work order they shared. The car is a 2024 EV6 Wind RWD with around 7,500 miles, in for nothing more than a tire rotation. The tech ran a KDS scan and found code P1A9096 stored in the vehicle, inspected the ICCU harness and harness pin tension (both within spec), and concluded the ICCU had an internal fault. Per Kia’s warranty bulletin (the work order cites WTY044), if the code is active the procedure is to replace the ICCU and its high-voltage fuse. That’s what they did – ICCU assembly, HV fuse, and a coolant top-off, all at no charge under warranty.

A couple of things stand out. First, this was caught before any symptom – the owner hadn’t experienced a single charging issue. According to the advisor, after dozens of ICCU tow-ins the techs at this store now routinely scan every E-GMP Kia for ICCU codes whenever one comes in for any service. That’s a real shift from the usual story, where the first sign of trouble is a dead car and a flatbed.

Second, and this is the part I’ve been waiting for: the replacement carries a build date of April 2026 (the owner pulled that from the IONIQ Companion app), and the part number on the work order is 36400-1XFA0AQQK – the revised number we’ve documented as shipping since roughly mid-January 2026. So we now have confirmation the revised part was still in production this spring, plus one data point (the advisor’s word) suggesting the replaced units aren’t failing again, at least not at this one dealer.

The caveats (AI generated): this is a single secondhand claim from one service advisor at one dealership, and “none have come back” is doing a lot of work in that sentence. The revised units have only been in cars for a few months, nowhere near enough time to call them durable – plenty of original ICCUs ran a year or more before letting go. The owner even raised the reports of replaced ICCUs failing, and the advisor simply said that hadn’t happened at their store. That’s not data, it’s the absence of data from one location. And a stored code that “signals a pending failure” is the dealer’s characterization, not something we can independently confirm points to a predictable, gradual failure. So treat this as encouraging, not conclusive. It’s the first faint signal on the question that actually matters, and I’ll keep collecting more.

ICCU Warranty Extensions: A Consolidated Look at All Markets

Hyundai Motor Group’s 15-year ICCU warranty extension started in South Korea in November 2025 and has rolled out market-by-market since. As of mid-May 2026, here’s where things stand — and where they don’t.

What’s been announced

South Korea (November 2025). Kia Corporation issued an official customer notice extending ICCU warranty coverage to 15 years / 400,000 km for all E-GMP vehicles (EV6, Ioniq 5, Ioniq 6, GV60, Electrified GV70, Electrified G80). Enrollment is automatic, and reimbursement is available for prior out-of-pocket ICCU repairs after July 24, 2022.

Europe (April 2026 onward). Hyundai and Kia German sales subsidiaries have extended ICCU warranties to 15 years / 300,000 km, with rollout continuing across other European markets. Coverage:

• Hyundai Ioniq 5 built before April 2024
• Hyundai Ioniq 6 built before September 2024 (per the Finnish Moottori report; the UK/Ireland communication listed April 2024 as the Ioniq 6 cutoff — the two notices differ on this detail)
• Kia EV6 and EV6 GT (pre-facelift) built before June 15, 2024

United Kingdom and Ireland (April 2026). Hyundai UK and Hyundai Ireland issued direct customer communications confirming 15 years / 300,000 km (186,000 mi) for Ioniq 5 and Ioniq 6 built before April 2024.

United States — Hyundai (April 21, 2026). Hyundai Motor America confirmed to Torque News that it’s extending ICCU coverage in the US to 15 years / 180,000 miles for affected Hyundai EVs. Model year and production date cutoffs have not been disclosed. Owners can check status by entering their VIN at HyundaiUSA.com/Campaignhome, though several outlets and forum threads have noted that the tool returns no campaign for many owners with affected model years — including some 2025 Ioniq 5 owners whose vehicles have already experienced ICCU failures. The campaign appears to still be rolling out.

United States — Kia (April 22, 2026). Kia America sent this letter to owners announcing an ICCU warranty extension for 2022-2024 MY EV6 vehicles only, raising coverage from 10 years / 100,000 miles to 15 years / 180,000 miles, whichever comes first, starting from the date the vehicle was first put into service. The extension covers free diagnosis plus ICCU and ICCU fuse replacement at no cost when symptoms (difficulty or inability to charge using Level 1 or 2 AC, V2L issues, or a “Check electric vehicle system” warning) trace to an ICCU malfunction. Owners who already paid out-of-pocket can submit reimbursement requests online at customercare.kiausa.com or by mail using the Request for Reimbursement form (WTY044) included with the letter. Kia says it will respond to claims within 60 days.

Canada — Hyundai and Genesis (late April 2026). Hyundai Auto Canada announced an ICCU warranty extension of 15 years / 290,000 km, no cost to customers. Sources differ on the exact date (Le Guide de l’auto reported April 22; Motor Illustrated reported April 27). Coverage:

• Hyundai Ioniq 5 (2022-2024)
• Hyundai Ioniq 6 (2023-2025)
• Genesis GV60 (2023-2024)
• Genesis Electrified GV70 (2023-2024)
• Genesis Electrified G80 (2023-2024)

Hyundai Auto Canada distributes the Genesis brand in Canada, which is why Genesis vehicles fell under the same announcement — unlike in the US, where Genesis Motor America is a separate entity and has not yet announced anything.

Canada — Kia (May 2026). Kia Canada has now followed suit, with letters arriving to EV6 owners announcing an ICCU warranty extension of 15 years / 290,000 km, no cost to customers, for 2022-2024 MY EV6 vehicles only. The mileage cap matches the Hyundai/Genesis Canada terms, and the model-year/EV6-only scope mirrors Kia America’s April 22 announcement. There is no EV9 coverage. Transport Canada recall 2024-700 (software update and component replacement as needed) remains in effect.

What’s still missing

Several markets and vehicle segments remain holdouts as of this writing.

• Genesis Motor America. No extension announced for Electrified GV70 or Electrified G80 owners in the US. Carscoops reached out and reportedly received no response. With Hyundai US, Kia US, Hyundai Canada, Genesis Canada, and now Kia Canada all in, GMA is the last North American Hyundai Motor Group brand without an extension.
• Kia EV9 (US). The April 22 Kia America letter is explicit: the extension covers 2022-2024 MY EV6 only. No mention of the EV9, despite earlier speculation that a parallel remedy was likely to include it.
• Australia. No extension from Hyundai, Kia, or Genesis. Australian owners launched a Change.org petition pushing for one.

Things to keep an eye on

The VIN-lookup mismatch. Multiple outlets and forum threads have flagged that the Hyundai US VIN lookup tool returns no campaign for many owners with affected model years. The campaign appears to be rolling out gradually, and some owners may need to call their dealer rather than rely on the online tool.

The mileage caps in context. The US and Canadian caps are effectively the same once converted — 180,000 miles vs. 290,000 km (about 180,200 miles). The European 300,000 km cap (about 186,000 miles) is just slightly more generous. South Korea’s 400,000 km cap (about 248,000 miles) is by far the most generous and has sometimes been characterized as effectively a lifetime warranty given the mileage.

If you own a 2022-2024 EV6 in the US: Watch your mailbox for the WTY044 letter from Kia America. Keep it in your glovebox per Kia’s instructions. Contact an authorized Kia dealer if you experience any of the symptoms listed in the letter. If you’ve already paid out-of-pocket for ICCU repairs since the vehicle was new, file a reimbursement request via customercare.kiausa.com.

If you own a 2022-2024 EV6 in Canada: Watch your mailbox for the Kia Canada letter and keep it with your vehicle records. Contact an authorized Kia Canada dealer if you experience AC charging issues, V2L issues, or a “Check electric vehicle system” warning. If you’ve already paid out-of-pocket for an ICCU repair, ask your dealer about reimbursement under the extension.

The full market-by-market breakdown is on the ICCU Report.

Class Action Lawsuit Filed Against Hyundai Kefico Over ICCU Failures

Aaaaand, we’re off. We knew we’d see a class action lawsuit sooner or later over the continuing ICCU saga, and now it has become reality. After multiple recalls and some people experiencing two or even three ICCU failures, it seems Hyundai Kefico, the manufacturer of said ICCUs, will have to answer to a judge (and potentially a jury) for Hyundai “replac[ing] defective integrated charging control units with equally defective ICCUs.” The lawsuit was filed in the U.S District Court for the District of New Jersey: Young, et al., v. Hyundai Kefico, Inc.

What’s interesting is that the article mentions the model years covered, but one of the plaintiffs - Roy A. Williams - leased a 2025 KIA EV6 in August 2025, but the list of affected vehicles given only mentions 2022-24 model year EV6s. Also, there is no 2023-24 GV80 Electrified, although one is mentioned in the filing as well.

Setting expectations (AI generated): class actions like this almost never produce clean answers to the technical questions. Most settle without admissions of liability, and the expert reports and internal documents that would actually tell us what’s wrong with the ICCU usually end up sealed. The most useful information will likely come out along the way (motion to dismiss rulings, class certification briefs, expert references in public motions) rather than from any final verdict. Realistically, this suit is more likely to function as a pressure vehicle, pushing Hyundai Motor Group to expand warranty extensions, accelerate revised-part rollout, or fund a settlement program, than as a fact-finding exercise that finally explains the defect. If you’re hoping for a definitive technical reckoning, that’s probably not what’s coming. If you’re hoping for movement, this is one of the levers that historically gets things moving.

NO, the EV6 subwoofer wasn’t wired wrong - Here’s proof

Ever since my wife and I rented an EV6 and fell in love with the car, the one thing that has always bugged me about it is the lackluster sound system. OK, maybe lackluster is too harsh a word. Meridian is supposed to be a “premium” brand, right? How could they put a “lackluster” sound system in a $60K automobile? I thought perhaps our rental had just been abused, but no - when we got our own EV6, we discovered it’s just the way it is.

I mean, it sounds fine - it’s certainly better than the system I had in my Wrangler (not a difficult task). My issue with it is that it sounds overprocessed. When it comes to audio/video, I’m not a fan of “enhancements.” First thing I do when I get a new TV is turn off all the motion interpolation, contrast enhancement, or whatever goodies the television manufacturers think give them a competitive edge. I always see it, and it’s annoying.

Maybe it’s the year and a half I spent in audio engineering school, but I feel the same way about my audio. I want it as close to how the artist wanted it presented as possible, and that means a pretty smooth response curve, and no extra processing.

The Meridian sound system in the EV6 just sounds like it has no punch, and it’s not because it’s lacking bass. There’s something else going on that I can’t place. All I know is it’s embarrassing that my 2019 Forester with the Harman Kardon sound system is literally one of the best sounding car audio systems I’ve had in a car going back 40 years, and I even had an Acura TSX Sport Wagon with the ELS Surround system - 10 speakers, 460 watts, co-engineered by Grammy-winning producer Elliot “ELS” Scheiner and Panasonic - and the EV6, a car that originally stickered for double what my Forester did, can’t compete.

So naturally, I went online to see if others felt the same way, which led me to a video called “The Kia EV6 Sound System Doesn’t Suck… It’s Just Wired WRONG!” by TechnicallyJeff (who is awesome and who has given a LOT to the EV6 community, so I’m not getting on him for this, I just think he’s incorrect here).

Cue the overjoyed forum posts about how much better the system sounds after a quick “fix.” I was skeptical. I mean, people love their Beats headphones, right? I’ve never been much of a bass-head. I like balanced sound. My favorite headphones are Sennheiser HD 650s. They’re not neutral, but they’re pretty close. And I mostly listen to indie rock (not generally the genre that would benefit from added bass).

I figured if Meridian wired the subwoofer a certain way, they probably did it intentionally. It would be a huge oversight to have wired it incorrectly.

But I did the swap anyway, and, well, I guess it sounded better?

The “fix” has been implemented in my car for six weeks or so now and it’s been … fine? But it always kind of bugged me that something just didn’t seem right.

And then today I saw a Reddit post where some hero went and actually did a physical measurement of what was going on, and boy was it illuminating.

I showed it to my son, who loves his sub-bass, and he said just today he had noticed when driving back from Queens in the EV6 that in one of the songs he liked that had quite a bit of sub-bass, it was just missing stuff he could hear in his car.

Looking at the chart from the post, we can see why.

So let’s get into it.

“Real REW Measurements for Subwoofer Polarity Hack in the EV6” by u/Loud-Produce-8230 is a comprehensive analysis of the EV6’s Meridian sound system. They went all-in: UMIK-1 calibrated measurement mic at the driver’s seat, Room EQ Wizard on a laptop, sweeps sent via Bluetooth, balance centered, EQ flat, Custom mode with Stereo 0 and Surround 0, car in Park so there’s no road noise. Then three overlaid frequency response traces:

• Yellow: front speakers only, subwoofer unplugged
• Blue: front speakers plus the factory-wired subwoofer
• Pink: front speakers plus the wire-swapped subwoofer (the “fix”)

Above 100 Hz all three traces sit right on top of each other - the subwoofer isn’t doing anything up there, so that’s expected. Below 100 Hz is where the real story lives.

In the 45–55 Hz region, pink runs about 5 dB louder than blue. That’s the “punchier bass” owners are hearing, and it’s real - it’s just confined to one narrow slice of the spectrum. But look right next to it, around 80 Hz: pink dips noticeably below both blue and yellow, so the swap actually loses emphasis in the upper-bass region just above the bump it creates. Step down to about 30 Hz and pink plunges into a deep notch - roughly 15 dB below the factory trace. Below 25 Hz, the factory actually extends deeper than the swap does.

Which brings us back to my son’s drive home from Queens. He wasn’t imagining it. In the factory-wired configuration, 30 Hz content (the body of kick drums, sub-bass drops, the fundamentals on deep synth lines) is present and integrated into the mix. Swap the wires and that content is canceled out. Your ears lock onto the 45–55 Hz bump and happily call it “bass,” and the missing 30 Hz slides by unnoticed, until a specific song puts something down there, and then it just… isn’t.

At the crossover region, where the door speakers are rolling off and the subwoofer is taking over, the two sources overlap. If they’re in phase, they sum. If they’re out of phase, they cancel. Meridian’s engineers tuned the sub’s phase so that around 30 Hz, the sub and mains add to each other. Flip the subwoofer’s polarity and that relationship inverts - now the sub and mains cancel at the crossover. You trade 15 dB of sub-bass for 5 dB of midbass excitement.

u/Loud-Produce-8230 puts it better than I can:

“In my view, it’s a bit pretentious to think that Meridian and Kia completely ignored proper engineering. I believe the subwoofer is intentionally designed for an ‘audiophile’ purpose to balance the bottom end rather than just racing for decibels.”

And on the viral testimonials:

“Even if I’m willing to admit that occasionally there’s a +7 dB difference in a tiny slice of the spectrum, I think there’s clearly a placebo effect in this excitement.”

The “fix” isn’t a fix. If you like a louder midbass bump and you don’t play much content that lives below 40 Hz, the swap might sound better to you. Fine. Nobody’s ear is wrong about what their ear prefers. But can we stop with the whole “Kia and Meridian got the wiring wrong”? They didn’t. The system is working as-intended / as-designed. Full stop.

And if, like me, your real complaint about the Meridian is that it sounds overprocessed, reversing the subwoofer’s polarity was never going to fix that problem. Whatever’s bugging us about this system, it’s upstream of the subwoofer.

So I’m putting my wires back this weekend. But I also discovered another tweak further down in the comments that was key to tuning the system closer to my preference.

u/sumthingcool notes “You probably don’t have your EQ/Meridian settings applied to the AA/BT inputs.”

All this time, I thought the “Authentic,” “Surround,” or “Custom” settings just didn’t apply to Android Auto and Apple CarPlay, and that changing the processing settings didn’t make any difference when using those phone-projection sources. I was wrong.

u/sumthingcool continues: “Setup -> Sound -> Connected Devices, select AA or CarPlay, then the button in the upper left corner to select the desired sound mode.”

Bingo. The answer for me? Set Android Auto to “Custom,” and then go into the Meridian processing settings (duh, labeled Custom, I should have known, right?) and pull both sliders all the way down to ZERO.

My music sounded better already. Now I just have to see how it sounds when I swap the subwoofer wires back. I know it’s not going to be a miracle, but at least now I have a much better idea of what’s actually going on with this system and how to get the audio at least slightly more accurate.

Full methodology, all five graphs, and the discussion are on the original Reddit post. It’s the kind of careful, honest measurement work this topic has been missing. If you feel like it, go give u/Loud-Produce-8230 some thanks.

Easter in New York: The 2026 NY International Auto Show

Easter in New York means the NY Auto Show, so on Easter Monday my son and I took the EV6 into Manhattan to check out what the automakers around the world are up to these days. A number of giant banners at the entrance signified that Hyundai Motor Group had spent some serious coin this year to promote their latest entries. And why not? Hyundai and Kia continue to break sales records, and Genesis just celebrated its one millionth sale overall — faster than any other luxury brand in history — and pledged 22 new or significantly enhanced vehicles in North America by 2030. It seems things are going gangbusters for the company.

On the showfloor, there was a lot to be excited about.

There’s been a lot of speculation in online forums that the EV6 is on its way out, as sales of that particular EV have slowed significantly, but a plaque in front of the new 2026 EV6 stated that the model was, indeed, “Coming Soon” to the US.

Although the new EV6 might be delayed, Kia did have some exciting news for EV6 owners (well, at least owners of 2025 models) — an upcoming software update will enable Vehicle-to-Home capability using the Wallbox Quasar 2. The Kia exhibit showed an EV9 connected to a Quasar 2 powering a model home, but the reps said the new model EV6 (years 2025+) will also be supported for V2H. You no longer have to spend megabucks on a Chevy Silverado if you want to power your home during a power outage. More info is available here online, and here’s the datasheet they were handing out at the show.

I hope my Forester lasts a while longer, since I just put some major money into suspension work on it, but if something happens to it, I’ll be looking at EV9s. Long Island is due for another major hurricane, and when Irene hit and then Sandy right after it, we were without power for a week each time. I have a generator, but when even the gas stations are out of power for days, people start getting a little sketchy. The sooner I get rid of gas entirely, the better.

Kia also had its upcoming EV3 (in the US market anyway) on display, something that should give the entry EV offerings from every other manufacturer a run for their money. I’ve seen a number of articles comparing the EV3 to the Chevy Bolt, but it seems more like an Equinox EV competitor to me. Both models have really nice interiors and a heavy “thunk” when the doors are shut, have similar range, and the EV3’s expected MSRP is likely to mirror the Equinox.

Kia says the EV3 will get up to 320 miles on a charge and offer, depending on trim level: AWD, Vehicle to Load (V2L), Head-Up Display, and all the safety features found on other Kia EVs. There will also be a high-performance GT model putting out 288 horsepower (up from 261 hp on standard AWD models) and a US-exclusive Nightfall black appearance package. Something else I think will be unique at this price point is the fact that the Vehicle to Home capability I mentioned above via the Wallbox will also be available on the EV3. With an 81.4 kWh battery on the non-Light versions of the vehicle, that’s enough to power the average house for a few days. Likely more if you’re careful. The model is expected to launch late 2026.

Kia was also showing its new Seltos, which is a real looker. Its “Converge” concept was stunning in a matte red. The design department really hit it out of the park with that one.

The excitement at Hyundai this year was, of course, the new body-on-frame concept, the “Boulder,” which debuted at the show. I spoke to a couple of Hyundai reps about it, and the consensus was that with this much excitement, it’s going to happen. First release is likely a gas model, followed by a hybrid, possibly a plug-in hybrid.

I asked about an EV, because an EV in this form factor is what I’m really looking for since Jeep doesn’t seem to want to get serious about it, and the answer wasn’t no, but it didn’t seem to be on the table yet. It’s likely that Hyundai wants to appeal to the mass market first with its truck entries (a midsize pickup will come before any SUV), so it makes sense that the demographic they’re targeting will prefer some type of gas powerplant.

I’m sure the company’s XRT wing is probably itching to work on its new body-on-frame entries. I don’t know what the XRT sales numbers look like overall, but Hyundai is clearly committed to the subbrand. There was a whole floor section featuring the ruggedized models.

I hadn’t yet seen an Ioniq 5 XRT up close, and it’s even more stunning in person. I can’t wait to see what the designers do with a pickup and Boulder.

Speaking of the Ioniq, Hyundai had N versions of the 5 and 6 on display. The US market drops the non-N 6 this year, thanks to tariffs (and probably slower sales).

I got a chance to speak with a Hyundai rep about the ICCU issues and he assured me that the company is taking the issue seriously. He noted that he was under the impression that Hyundai Motor Group was shipping a revised part. I asked if it was a revised part number or a revised part. That’s when he said my local dealer would probably be the best one to consult about that. I emphasized that the dealer network was part of the problem — that reports were inconsistent at best, and the community was getting different answers from every dealer. He said part of his job at the show was taking the daily feedback he got from people on the floor and moving it up the chain.

My feedback was simply that I understood that there were likely legal reasons why HMG was not communicating with owners, but that communication would go a long way and that perhaps the company could become more involved with the community at large. I relayed how many people online claim these are the best cars they’ve ever owned, and how disheartening it is that we have to hesitate when recommending them. I know one person’s feedback from an auto show won’t likely have much of an impact, but I figured it was my chance to be heard directly, so I took advantage of the opportunity.

Next, I headed over to the Genesis exhibit. I think they’re going to hit their two millionth car in an even shorter period of time than they did their first. The hot model was the GV60 Magma, and it was the only car in the show that was swamped so much of the time I had to come back just to get a picture of it. The thing looks absolutely sinister, and the interior is the best combo of sport and luxury.

You can read (and hear) all about the Magma line here on the Genesis site. Plenty of YouTube influencers have covered it as well, so there’s quite a bit online about it already. It was just something else to see it in person.

Having come from the Saab world, I’m a huge fan of wagons. So it was with great joy that I saw Genesis’ latest totally bonkers take on a wagon concept, the G90 Wingback. Yeah, it’s not an EV, and I said I’d never buy another gasoline-powered car, but good god, if there was ever an argument for one last splurge on petrol, this would be it. The thing is an absolute monster. I love that the Genesis designers not only took this on, but that the company decided to bring it to the show. Talk about bold.

And speaking of bold, I got huge Genesis envy from the screen on the Electrified GV70. The 27-inch OLED panel looked absolutely stunning — clear and crisp, with super-bright whites and deep dark blacks — like they took a slice off my Sony A80J and put it in a car.

Some other quick impressions: Hyundai Motor Group was showing off its controlling stake in Boston Dynamics with a few Spot models dancing in sync by the Hyundai exhibit and interacting with kids by the Genesis area. They were a big hit.

Nissan was trying to convince everyone that it was the fastest growing brand in America (that’s what the sign said, although the dates in fine print seemed suspiciously cherry-picked). It’s too bad they’re hurting, because the new Leaf sure seems like an awesome redesign.

Ford made good on its promise to backtrack on EV investment by bringing exactly two EVs to the show — a Mach-E and... another Mach-E. Boo.

Toyota’s spokespeople were the most enthusiastic, and really whipped up the crowd as they covered all the electrification progress they’ve made with their fleet. Every time I walked by, there were amplified claims about how much they were investing in the electrified future. Good on them, but it would have been nice if they hadn’t been talking down the EV future every chance they got over the last few years.

Subaru’s tie-in with Toyota has served the smaller automaker very well — their new EV line was featured prominently off the main concourse, and they had two versions of their new Getaway three-row version of the Highlander EV. You could tell they were prototypes though, as they were conspicuously devoid of body cladding.

Yeah, that’s a joke, but... not really? I love what Subaru is doing here, and hope they find a lot of success with their EVs, which seem to be priced quite a bit more competitively than the equivalent Toyota models.

Over at the Jeep exhibit, everyone was trying to get into the doorless, windowless Recon. I witnessed the reps telling three people on three separate occasions to please not sit in the vehicle — it was roped off, but people didn’t seem to care. They had two models, and the other was locked. I’m still not sure what to think about it. People seemed to be interested in it, but perhaps they hadn’t seen the range (230 miles) or the price tag (starting at $65K). I’m not sure who this vehicle is for, but I guess we’ll find out soon. I like it, I just don’t think I’d trust it, especially after the 4xe debacle. The R2 and Scout (if/when it arrives) are likely to do far better in the American market.

The Lucid exhibit was mobbed most of the time, so I pretty much stayed away from it. It was good to see the enthusiasm around the brand though.

Downstairs were the usual vendor exhibits and EV track. I took a ride in an EV9 just to see how it handled. EVs are wild, man. That you can take this heavy of an SUV, in totally stock form, and throw it around a track like that is just insanity. I’ll close with the pic I took in a lonely corner of the basement, where the NY Power Authority had a wrapped EV6 on display. Pretty cool. There wasn’t much buzz around the EVolve NY exhibit, but overall, there did seem to be a lot of EV enthusiasm from both attendees and the auto manufacturers themselves.

EV adoption might be slowing in the States, but it’s not stopping. I know sometimes I think NY is the center of the universe just because I happen to live here, so maybe it’s just a city thing, but I don’t think so. The future seems inevitable. It’s just going to take a little longer than we thought it would.

I’m biased, of course, but I thought Hyundai Motor Group had the strongest overall presence at the show. Through three sister brands, it showed its commitment to three distinct audiences even while sharing platforms. If you liked gas-powered vehicles or hybrids, there was plenty there for you. And if you are as jazzed as I am about our electrified future, there was no apologizing from HMG — they’re charging ahead on all fronts.

The NY Auto Show runs through April 12th at the Javits Center in Manhattan.

ICCU Warranty Extended to 15 Years Across Multiple Markets

In what is arguably the most significant ICCU development to date, Hyundai Motor Group is rolling out 15-year ICCU warranty extensions across multiple markets. Here’s what we know so far.

South Korea (November 2025). Kia Corporation issued an official customer notice confirming that all E-GMP vehicles subject to the ICCU recall — including the EV6, Ioniq 5, Ioniq 6, GV60, Electrified GV70, and Electrified G80 — will have their ICCU warranty extended from 10 years / 160,000 km to 15 years / 400,000 km. Enrollment is automatic. The notice also confirms that customers who paid out-of-pocket for ICCU repairs after July 24, 2022 may be eligible for reimbursement. Some outlets have described this as effectively a lifetime warranty given the mileage cap. This extension was first announced in November 2025, following the Korean ICCU recall that took effect December 9, 2024.

Europe (April 2026). Finnish auto journal Moottori received confirmation from Hyundai Motor Europe that all Ioniq 5s built before April 2024 and Ioniq 6s built before September 2024 will have their ICCU warranties extended to 15 years or 300,000 km. The report suggests more information may be available this summer.

United Kingdom and Ireland (April 2026). Hyundai UK and Hyundai Ireland have issued direct customer communications: “Hyundai has decided to extend warranty cover on the ICCU (Integrated Charging Control Unit) for IONIQ 5 and IONIQ 6 vehicles produced before April 2024 to 15 years from first date of registration or up to 300,000kms (186,000miles), whichever comes first.” Note a slight discrepancy with the Finland report: the UK/Ireland notice lists April 2024 as the production cutoff for both models, while the Moottori report listed September 2024 for the Ioniq 6.

Software update and hardware revision confirmed. A direct letter from Hyundai Motor UK’s Senior Executive Office Case Manager, shared in the Hyundai IONIQ 5 UK Owners Facebook group, adds two significant details not found in the other notices. First, Hyundai confirms they are “working to provide a new free software update which will mitigate the risk of any further issues.” This is the first official acknowledgment of an incoming software-based mitigation. Second, the letter states that “all IONIQ 5 vehicles produced after April 2024 have been built with an enhanced ICCU featuring improved design elements.” This is the first official confirmation that the ICCU hardware itself has been revised, with April 2024 as the cutoff between old and new designs — at least for the Ioniq 5. It is worth noting, however, that ICCU failures have been reported in 2025 and 2026 model year Ioniq 5 vehicles, which would have been produced after this cutoff.

What’s still missing. There is no word yet on whether similar extensions will apply in the United States, where ICCU coverage currently stands at 10 years / 100,000 miles. Australia has also not received an extension, and owners there have launched a Change.org petition pushing for one. It also remains unclear whether Kia and Genesis vehicles outside South Korea will be covered under the broader E-GMP extension, or only the Hyundai models named in the European communications.

Thank You to the Community

Well, this site, and the ICCU Report page in particular, got a lot more attention than I ever intended. I can't say thank you enough to all the electrical engineers and to the E-GMP community for helping me correct and streamline the page.

We all know since there is no actual fix for the issue, we are all more or less spinning our wheels on this, but my goal was always to just put as much of the "what we know" on a single page, so people who are just finding out about it don't necessarily have to wade through thousands of Reddit or E-GMP forum posts trying to figure out if there's anything they can do to potentially stave off the dreaded turtle logo appearing on their screens. I hope it's a starting point for digging, not an end. The page has recommendations, but as I said, we don't know if they'll help. We only know what the failure is, and what steps and practices typically slow down that type of degradation in other settings.

Again, thank you all for keeping me honest, and for pushing me to hone the page down to what we know, and to get rid of as much speculation (and any inaccuracies) as I could. My goal is transparency, and you can find all corrections to that page from the changelog link at the bottom of that page. I don't expect to be changing much on the page at this point, and if there's new news or recommendations, I'll add it here, and then include it in the report if warranted.

Cheers, everyone. Thanks for checking out the page. And may we all have many, many trouble-free miles in our E-GMP EVs!

Welcome to the News Page

Thanks for visiting egmpfiles.com. The site has gained a bit of traffic over the last few days, and I've just added this blog section so that I can keep my original E-GMP page static based on the date it was written, and still cover things I find interesting in the EV space, with a particular focus on Hyundai, Kia, and Genesis.

When there's new information about the ICCU issue, I'll note it here, and then integrate it into the ICCU Report page where warranted, so that the report will always be the latest up-to-date and most comprehensive overview of the entire issue that's publicly available.

I've also implemented a changelog for the ICCU Report, and a link to it can be found at the bottom of that page, right after the source list. Any time there's new or updated information, or even information removed, the date, time, and reason will be listed on that page.

If there's something I missed, or something I got wrong, you can always send me an email and I'd be happy to add to or correct the record. At the end of the day, it's more important for me to present accurate information than it is to preserve my ego. I'm sure I'll get some things wrong, but when I do, I'll try to remedy it as soon as possible. Most of us just love these cars and just want to keep driving them for as long as we can. That's really what this site is about. Thanks for being here.
