I have seen most of Your posts and have found them to be very informative and helpful.

[@williamfeiring]

As always Corbin, thanks for keeping us updated on all things Hyundai, Kia and Genesis Evs. Though I love my 2022 I5 Limited, like a lot of us I am getting tired of the trips to the dealer. At the dealer I bought my I5 from, it takes over a month for me to get a service appointment and I called just after seeing this video. First available appointment was January 3rd. Called another dealer who said middle of December. In October my 12 volt started to die (like a lot of us) and when I called the dealer they said I could bring it in for them to test it the following week, but made no promises about when they could replace it. I ended up buying the AGM Weize (works great thanks again Corbin) and installing it myself. I did reach out to customer care and they sent me a check for the battery.

[@vlad2838]

Really sorry to see this repeat debacle. I was the proud owner of an Ioniq 5 until seeing the first ICCU issue, at which point I pulled the plug and went Model Y. I loathe Musk, but hate being without a car even more so.

[@justanotherguy7798]

Thanks for the update and by the way I watched you on the Out of Spec race across the country it was a fun and educating video great job.

[@caglioso]

I scheduled the service for it and luckily my dealership put me in for their earliest appointment……in mid January.

[@RonMilesLokheed]

I was at the dealership this morning for an already-scheduled regular maintenance, and when I checked in they mentioned the recall and offered to do it at the same time. I have fortunately not had any ICCU issues yet. All total I was there for about 2 1/2 hours, and the recall was completed successfully.

[@flolou8496]

What exactly did they do? It sound's like it's a faulty ICCU (which is a large piece of hardware the size of a large King Size Pillow) is determined defective now, is not fixed via software, but a hardware change, that sound's rather involved, taking hours ????

[@alexwong402012]

I experienced this issue last week, and then a few days later, the recall was issued. I did the software update recall a few months ago.

[@axion8788]

Logged on to Hyundai's site this morning and booked an appointment for tomorrow in Albany, NY.

[@JohnMarquette]

This vehicle has failed on me twice. I’m done with it. 2022 Limited, 49k miles

[@JacGoudsmit]

Just last week, I had my 2023 Ioniq5 12V battery replaced under warranty because it wouldn't hold a charge anymore after I used the compressor that was included with the car to inflate a slow leaking tire. They also did a recall that had something to do with Level 2 charging. I guess I'll have to take it in again. Nice that Hyundai is staying on top of this, but it sure would be nice if they could program those ICCUs over the air...

[@pdculbert]

Ironically, my ICCU died 2 days after this recall was announced. Fortunately my dealer had one in stock, so it was fixed in 1 day. At least I managed to get the updated software at the same time!

[@richwesterman1391]

What a coincidence. I just got my '22 I5 SEL back from the dealer after having the Iccu replaced. They had it 2 months and tried several different fixes (replace charger door!) before the final fix. Hyundai national got involved and worked with the dealer to find the final solution. I was given a brand new Sonata loaner and was reimbursed by national for the week's rental cost before they gave me the loaner. The problem announced itself when I tried to charge with my level 2 home charger. It would begin to charge and then 'click' the charging would halt. My local service dept was mostly unfamiliar with EV repairs, it seemed, so they depended on national to steer them to the solution. This was the first problem the car had given me in over 2 years. Hats off to national for making what could have been a real pain in ass into a mostly painless process. If this happens to your I5, go straight to national and request that they monitor the repair process. The dealer was Phillips Hyundai in Bradley, IL.

[@flolou8496]

I am in the market for a used IONIQ 5 from the 2022 or 2023 model years, can you tell me what you mean by ''go National'' if my own local dealerships in Las Vegas, are also in the dark about how to fix the latest ICCU issues based on the latest re-call ?

[@jimchoff]

Considering this car. Not buying until they fix this.

[@83chanman]

Thanks! Just checked mine and there is another recall for this, I called to make an appointment at a local dealer and they said it’s not that urgent and I can book it after the holidays. Let’s hope! 🤞🏼

[@jean-marcfiliatrault266]

I put a BMS on the OEM lead-acid 12-volt battery. It cycles once per day. 1) This is not normal. No wonder it does not last the typical 5 years as a typical “starting” lead-acid battery would. A deed-cycle battery instead of a starting battery would be a better fit for the 12-volt battery. 2) Regardless, something is draining this 12-volt battery. Therefore, I’d be real surprised if the ICCU charging is the root cause.

[@dperreno]

Thanks for the detailed update! I'll call my dealer and see if they can do this update before Christmas.

[@kazemi88]

I saw this recall on TikTok lol. It is getting annoying to have to do this 2x in one year…

[@lanceareadbhar]

Welcome to the club. I've had two different Ioniqs since December 2021 and this has been a 9 month ritual with the hope that this is the last time. Hopefully they will eventually have a final fix, but at the same time I love these cars so much that this being the only flaw to me feels like a blessing given the crapshoot that comes with buying 1st generation cars.

[@kazemi88]

@ you are right. I do love the car and the newest update fixed the bad sound quality and that blew me away. So yes, even iPhones have to have massive updates so a car this innovative makes a little sense.

[@tunnagan]

Thank you for the heads up! I am about to pick up an Ioniq 5, I will make sure the dealership looks into this before I drive it off the lot.

[@TheIoniqGuy]

They’re legally required to install the update before you can purchase the car

[@petekraemer2538]

I just finished an eight service adventure with my 22 Ionic 5 RWD. It started with my inability to slow charge my Ionic5. It would charge DC (level 3) no problem but level 1 and 2 charging would not work. It would start the charge for about 10 seconds and then announce the charge "terminated". I took the car into my local Hyundai dealer 3 times over 3 weeks then, on my fourth visit they said they needed the vehicle on site so they could investigate further using external (national) resources. I was given a loaner. Finally following 6 weeks of work I was informed that the ICCU had to be replaced and this would require an addition 2 weeks of work and testing. I got my Ionic 5 back in full working order.

[@flolou8496]

Thank you for posting this, I'm currently in the market for a used IONIQ 5, so I'm following all of this closely, but I'm confused still on what the latest recall still means: Does it appear in your opinion that if the dealership's determine your IONIQ 5 (either 2022 or 2023 model year) has some type of ICCU defect, it's more likely now, your getting a entirely new ICCU , right away , or do you still face an uphill battle with long drawn out software patches first?

[@petekraemer2538]

@flolou8496 Hyundai is now investigating all 22, 23 Ionic 5 s for this issue.

[@ev_kimchi]

Perfect timing for our scheduled service appointment today for our Ioniq 5, hopefully the dealer only has to press the buttons. Question: is there any way to read the DTC codes ourselves without paying for the expensive special tablet the dealer has that HMG charges $5000 to get?

[@ev_kimchi]

eg, can this DTC code that leads to ICCU replacement be seen in Car Scanner?

[@russellmulvihill157]

Got mine for Mt ev6. Had it in for service because charging fails when I try and run the climate, and had then run the update too.

[@rijoshj]

Corbin, thank you for staying on top all our issues and presenting solutions. Really appreciate it. I just did the recall. In my case, there were no codes and they did the software update. My car was needing jumpstart over the past 2-3 weeks and the voltage went around 9.7V. Once it is running, voltage held around 13.5-14.3. Do you know how the 12V is charged while the car is being driven? Is that done by ICCU? I asked this to the service people at the dealership and they were throwing jumbo mumbo at me. So basically they are clueless. reason is, this past weekend i jumpstarted the car and drove it for 60 miles. I tried starting it back up after 15 minutes and the car was completely dead.

[@DAReeseDroid]

My battery was at exactly the same voltage and was replaced, but it took them keeping it for a few days to have the battery die after charging it.

[@wesbishop3790]

FYI: The Kia EV9 uses a different system that has a really cool motor that is designed to reconfigure the internal windings between delta and wye. It does this on the fly to make it more efficient whether needing torque or high speeds. Check out the Munro Live tear down of the Kia EV9 motor for more information.

[@RamonLisojo]

it is so weird that my App was showing the notification that the car need to be taken to service and all of the sudden the notification dessapered . I hope is a good sign and nothing is wrong.

[@dianewallace6064]

Getting my 7500 miles tire rotation for the Ioniq 6 SE AWD in December so all good.

[@v1nnyc]

They need to just recal and swap every iccu for a revised version

[@lanceareadbhar]

They'll only replace it if it's showing signs of a problem at least they are checking it for free each time. It would take years to replace them all with your car being in the shop for a while possibly getting something it doesn't need while they up the prices of everything to pay for such a recall.

[@granthenkins2675]

I’ve had absolutely no problems with my 2022 Ioniq 5 Limited until last week. (I purchased the car in June 2020.) I was taking my wife to the hospital for surgery when I received the notice to check the car’s electrical system. The car soon went into turtle mode but I was able to get it back home and use our other car for the hospital trip. I’ve made an appointment with my Hyundai dealer for Monday to have the car fixed. Sure hope this is the last time we have to deal with this issue. Good luck to everyone and, based on my experience, I wouldn’t wait to have your cars serviced.

[@seveglider8406]

I never had any problems charging my 2023 Ioniq 6 at a Super Charging station or at home with my Emporia Level 2 charger. However I have installed all Softwesr upgrades. I learned of this issue on Nov. 23 and was able to schedule an appointment on Nov. 26. Thank You!

[@741662027]

I'm in the US, and just had my recall handled today (2024 Limited). It took two hours. They said the time depended on their network bandwidth to download the software fix. The repair order showed that they did not have to replace the ICCU (quantity zero for part 36400-1XAA0-QQH, ICCU ASSY). They ordered a high-voltage fuse (375F2-GI040-QQH), which I assume I'll have to come back to have replaced. My service advisor gave me two tips: don't park the car with less than 20% battery unless you start charging it right away (so that the 12V battery doesn't go dead), and also to turn the headlights on during the daytime. This drains the 12V battery, which triggers the drive battery to recharge it and keep it healthy. He also warned against car washes that clean the undercarriage, because that's where the big battery lives. He says it's well-protected, but still... Great advice!

[@ev_kimchi]

EV6 GT was in on Wednesday and that too just needed the software update, out in about an hour, no drama. Putnam KIA in the Bay Area has generally been a good experience if you need a dealer who knows what they are doing.

[@RickF-m2x]

My Hyundai dealer is on top of this. Last Friday I made an early December appointment for routine scheduled service and upon reviewing the appointment confirmation they had listed this recall automatically without me having to mention it, which is good since I didn't even know about it until now. Nice to see them being proactive.

[@MrHockey1720-G]

Hopefully they will have the software patch by then. I called today and they don't have it.

[@alexandervs3369]

EV9 might be excluded because it already has CCnC from the beginning and my update it’s ICCU over the air?

[@leslarson2642]

Had an ICCU and battery replacement a couple of weeks ago. At dealership this moment to have all terrain tires installed and was told of the latest update, which will be installed today. No idea of the changes. According to the dealer, the new battery is an AGM type.

[@markduff4742]

Have to say the last ICCU fix was simple and brief, did it during a tire rotation. Hopefully this one will be the same. I've had no problems with my 2023 Ioniq 5 12V battery so far.

[@milohobo9186]

This is good information. I am learning about all the cars and their issues now so that when we replace my wife's ICE car I'll know what issues each car has because I plan on buying used. It looks like Hyundai and Kia are out. It was bever going to be a Tesla. Maybe a Mach-e?

[@Alejandro-ut4up]

It seems like every 6 months that I have scheduled service due with my GV60 there is yet again another recall. The upside is that Genesis still picks up my car and leaves me a loaner at my convenience so no real skin off my nose at least while I still have warranty coverage. I suspect I will be cutting the car loose at that point if they can't get their recalls under control. Last service visit I asked my service advisor about any resolution to the AC charge port overheating issue, nope, apparently Hyundai still working on it. Really its been 2 years. I kind of feel like they are tossing out questionably useful software band aids for clearly significant hardware problems and hoping it buys they more time to kick the can further down the road.

[@trainingtheworld5093]

Ioniq 5 owner here. Sadly I think you’re right. They’re just giving band aids to cover up serious problems. We are in a hot country (Australia) and we can’t AC charge at full current as the car will overheat. 4kW AC charging is embarrassing.

[@bennyhonna]

Always something with my G70, too.. I finally said screw it and ditched Hyundai Child Labor Group, altogether. Looking at EVs, but not looking here lol

[@richwesterman1391]

I've had an I5 SEL for 2 1/2 years and this was the first thing that went wrong with it. They fixed it (see my post above,) and I like the car so much that I'm getting a '25 when they come in to the dealership. It's the best car I've owned. I'm 77 and I've owned a lot of different brands and models. This is my favorite.

[@keegan854]

EVs are still pretty new tech. The Mach-E had the HVBJB recall which is a very similar issue. Tesla has had plenty of issues over the years too. For that matter, combustion cars have recalls all the time too -- Toyota just recalled 100,000 vehicles for machining debris in the engine which can cause loss of power. It's a pain but I don't feel (yet) like this is a reason not to buy Hyundai/Kia. You can make your own call of course. Nothing wrong with waiting a few years to get an EV, the tech will be more mature and you can also get a model with NACS (assuming you're in North America).

[@peterwright837]

I don’t see a recall listed for my EV6. Do you know if this is necessary if I already had the ICCU replaced?

[@boricua_in_wa]

Thanks, Corbin!

[@lotterynj]

Just had my service done and asked about said recall. Service advisor had no ideal but had patience and boom found it checked with service tech to ensure they could perform it. Boom took almost 2hrs but it was done. Never had any issues even for the first recall. Fingers crossed don’t have this. Only issue I had was the added miles to get the first recall done. It a lease and Hyundai finance doesn’t give you credit for those miles incurred 😡.

[@jamiebel4319]

Corbin, My ICCU has been updated and my 12v was replaced last Feb. I am concerned. Is it normal for my 12v charge indicator light to be on very frequently? It seems crazy that the ICCU needs to tend to the 12v so much.

[@ev_kimchi]

We had this recall done on our Ioniq 5 Ltd AWD this morning, and our dealer took less than two hours to complete it (just needed the software update, no ICCU DTC)

[@TheIoniqGuy]

Glad to hear no hardware replacement needed!

[@jerrymildredpetersen3177]

What a coinkidink!! I just got home from dropping off my '24 Ioniq 5 for that recall. I didn't get any notice of it. I was there for a previous recall on the tire inflator kit that they didn't get replaced due to our hurricanes. They said they could start right away on the ICCU work but might not finish it today since it was early afternoon when I dropped off the car. I think they jumped on it right away because they were a little embarrassed at having dropped the ball on the inflator recall. 🤫 I've never had any issues with the ICCU and have 12,300 miles on it since buying it in April. Thanks for all the details and have a great Thanksgiving!

[@jerrymildredpetersen3177]

Update: I had the latest ICCU recall done yesterday. It's the 272 campaign. They checked for codes (none found), checked the fuse (OK), and updated the software. I've only driven it the two miles home from the dealer so far. I checked my BM2 data just now and it looks perfectly normal. On a side note, I'm pretty impressed by these folks. They actually have three EV certified techs and they have treated me great even though they're in the middle of a major remodeling project.

@@jerrymildredpetersen3177 Hmm--I called my dealer here in Minnesota and they said they did not have the 272 software patch as yet and that it could take up to 30 days. I hope they updated your software with the new patch. Funny that this cannot be done remotely?

[@jerrymildredpetersen3177]

@@MrHockey1720-G Corbin said all dealers know about it, but I don't think they all dealers get updates right away. Some might not get it till January when Hyundai mails out letters to affected owners. My local dealer sells lots of EVs, so they probably get first dibs on that stuff. I didn't go in asking for it, but they told me I was "on the list." When they are ready to do yours, you'll know by going to the service scheduling page in your Hyundai app. There will be a bright red banner saying you have an active recall. It's shown at 2:09 in Corbin's video. Plus, my dealer paperwork says it was campaign 272. Hyundai, like most if not all legacy auto makers does not do OTA updates for anything but navigation and infotainment. Maybe someday, but I'd sure hate to get halfway through an OTA update and have a communications fault that bricks my car. It's bad enough when that happens with computers.

[@dobrzpe]

i'm wondering the same... :/

[@dguy321]

The blacked out display isn't a 12v issue. The root cause for a couple I've seen reported were caused by a failure to apply thermal gel to the heatsink on the gpu. One instance had a plastic film that was supposed to be removed, but wasn't, preventing proper cooling of the chip leading to periodic screen blackouts which recovered after the chip cooled enough.

[@MrHockey1720-G]

[@colbyconner3206]

At this point, Im convinced there’s zero safety margin for the dielectrics in the ICCU. They can probably tolerate 700V in theory but those pesky inductances will cause spikes above that when it tries to stop charging and the dielectric eventually fails. They probably found the worst corner cases and “patched” it with software to get the spikes low enough that the EV9 can live with its lower voltage. I’d guess that each subsequent software update is helping more of the corner cases which will make the ICCUs last longer but I doubt they’ll be reliable long term, akin to ford transmissions…

[@M0j0]

I had my ICCU replaced earlier this year after it unexpectedly went pop from the rear seat and I got as far as my 12v battery lasted. I was off the road for 6 weeks as parts were sourced. I think the clock is ticking on all of them.. I feel sooner or later they all need to be fully replaced.

Thanks though for finally helping me understand why my Ioniq 6 doesn't get these additional OTA updates.

[@scott4427]

@ I’m with you tbh. Would like some OTA functionality but any systems that can do OTA are also vulnerable to security issues.

[@jimross623]

Hi, I got my UK version Model Year 2025 (MY25) IONIQ 5 N Line S AWD last week. It’s great. With a rear windscreen wiper! I bought a magnetic sunglasses holder and a charging port lights blocker from you on Etsy. The sunglasses holder is great, but the item to hide the lights during charging does not (a) cover the newly-designed charger lights, and (b) won’t fit anywhere when you close the charge door… it’s just not the right shape for the new design. MY25 items from your on-line shop will need to be amended/redesigned to fit. Thought you’d like to know. Jim

[@alexbenh]

I didn't see the Ioniq 5N listed as an affected vehicle either. Unless it's considered to be an Ioniq 5 (I feel like it's often listed as a different car but maybe they just consider it a trim level).

[@scott4427]

@TheIoniqGuy in an older video you seemed to question the AGM battery, have you come around on that? I see you have linked the one you use.

[@TheIoniqGuy]

Yes, I was hesitant but someone that works in engineering at Hyundai told me that it would be fine with an AGM and I think the months of using one have proven that accurate

[@scott4427]

@ thanks for the follow up👍🏻

[@scott4427]

@ oddly, the battery you linked on Amazon says it doesn’t fit the Ioniq 5 if you use their vehicle fitment software… yet other AGM batteries of the same Group Size do. Weird.

[@Yanquetino]

Boy, those ICCUs are sure a tricky piece of equipment. I guess we can only hope that THIS time they fix the problem, once and for all. Shall we hold our breath? One question I have is: if the amber light on my dashboard periodically turns on, indicating that the 12V battery is being charged, does that mean my ICCU is working okay? Do those whose ICCUs have failed NOT see that amber light ever? Maybe it's a way to check?

[@lanceareadbhar]

Interesting idea as I see the amber light on often and have yet to have this issue owning two different Ioniqs (2022 Ioniq 5 RWD and 2024 Ioniq 6 AWD). This probably isn't the last time unfortunately given how often this happens, but what is surprising to me is how they haven't been able to eliminate certain EVs that were manufactured during any of the time periods from this recall or excluded any EVs based on having any of previous recalls done. This feels like more of a doctor visit every 9-12 months just to check that everything looks good and here's your medicine that should keep you healthy for at least another 9-12 months, but maybe longer if we're lucky.

[@scynt]

Ive been through 3 horns now on my Kona 24 ev. Along with the Lights completly GOING OUT AT NIGHT. They have no clue why my horns are failing, and no error codes to the LIGHT ISSUE THAT MULTIPLE PEOPLE ARE HAVING. im so over hyundai i cant wait to lemon law this car.

[@TennisTD]

Mine failed on my plug in Tucson. 3k into driving it

[@Trubyd44]

I have a 2025 Ioniq 5 N. Does this recall effect my vehicle? I did not have anything listed in my bluelink app. Thank you.

[@TheIoniqGuy]

No, 5 N is not recalled

[@Trubyd44]

@TheIoniqGuy Thank you for the quick reply! Appreciate it.

[@unclefreddy2009]

I definitely buy into the theory that this is Hyundai’s way of delaying NHTSA from fining them and frankly eventually leading to the buyback of these models similar to what VW had to do. The constant tweaking of software won’t fix anything, it’s a bad design and I am unclear there is any fixing that can be done or it would be. Think about it, it’s been a year or more now and there have been multiple updates. Do you really think Hyundai engineering hasn’t been able to figure out the real fix? I call BS completely here. It’s a shell game of updates. For example: I owned a Kia optima years ago. Hyundai messed up the engines and left metal debris in those when manufacturing them (Hyundai sonata too). They literally gave everyone who had problems a complete engine overhaul for free. If they had a solution to the iccu issue they would do it.

[@bigbertha8]

How long does this take? Wondering if I can wait for it to be done or if it's a drop off and pick up later kind of deal.

[@jamesrea329]

If it just needs a software update you can wait for it. But if they find the ICCU needs replacement that will take much longer. Unfortunately there’s no way to know until they actually run the diagnostic.

[@seveglider8406]

Thanks!

[@TheIoniqGuy]

Thank you so much!

[@BeepasGarage]

Perfect, just got the older update last weekend... -_-

[@CoFRTheGamerXxX]

So disappointing that iccu failure is still a thing.

[@labaom]

If you already had your ICCU replaced (mine a few months ago) will I still be affected? I do not see anything on the Kia website.

[@TheIoniqGuy]

I would say yes since they didn't begin implementing the software update on the production line until a few weeks ago

[@scott4427]

Yes. It supersedes prior recalls.

[@ev_kimchi]

YES -- we have an Ioniq 5 *and* EV6 GT .... Hyundai already has our VIN listed as needing the recall, but even though the EV6 also needs it, KIA hasn't attached the recall to our VIN yet. Your new ICCU might not need replacing, but you definitely need the new logic to properly protect it from damage due to thermals and on-off arcing

[@agentshiv]

Do you have the Hyundai recall pdf that would list the new ICCU version number? I need that before going into my dealer. Last time when I went in for the VCMS L2 charging fix, they claimed there was no update available and marked the campaign as completed. I had to raise hell as the software version was still the old one. They finally took me in the back and showed me on their tablet where it popped up in auto mode but supposedly the tech was trained to ignore and go into manual mode and did not see anything. Basically had to show the tech and service manager how to do the update lol.

[@ev_kimchi]

sounds like you need a better dealer?

[@flolou8496]

That is awful, I'm fearing the worst outcome and experience if this happens to me, any headway on your PDF ICCU version new # to pass that along to my own dealer or at a minimum double-check they know what they're doing?

[@mirasadful]

AGM battery installation- can this only be done by the hyundai dealership or any mechanic will be able to do it?

[@TheIoniqGuy]

Dealership likely won't install anything that's not theirs. Any other shop would do it. If you bought an AGM from any auto parts store, they'll likely install it for free.

[@mirasadful]

@ great. Thanks for the reply I thought it may need some technical fix or attachment with the high voltage battery. I am based in Australia. Recently got my ICCU fixed. Would change my 12v battery now and will be using BMS to keep an eye on 12V battery. Hope we get the 2nd recall soon in Australia and this ICCU issue gets sorted for ever

[@maikydb]

Aaah so that is why my dealler wanted my car in so fast.

[@dobrzpe]

i wonder if this applies to the Ioniq 5 N's.... no one has confirmed it as of yet, but they ARE "Ioniq's" and (as far as i know) have the same ICCU.

[@TheIoniqGuy]

It doesn’t apply to 5 N

[@eevie03]

Is this relevant to the UK as well?

[@TheIoniqGuy]

It will recalled everywhere

[@garyclark6747]

My NHTSA app give me a heads up and the dealership kindly return I inquiry at my request to let me know they were ready to roll so this should be done for us Wednesday. 🤞🏼 I hope this is the last one before the lease is up in a year and a half. 8:27

[@eddi3x3]

This won't be the last ICCU recall I bet given the stories on reddit. I'm pretty sure they'll eventually do a recall to replace the ICCU with a new model with less faults at some point otherwise they will lose money constantly dealing with these ICCU recalls.

[@dperreno]

I think you're right. Up until now they've been tweaking the software so that the hardware doesn't break, but the real fix needs to be a new hardware design.

[@eddi3x3]

@dperreno now what would be REALLY great is if they somehow not only change to a better ICCU but enable higher charge speeds at tesla super chargers than the current 100 kw limit for first gen cars

[@dperreno]

@@eddi3x3 My understanding is that that limit is more a function of the supercharger design (500V max vs. 1000V max on CCS stations) than it is a problem with our cars. This is because all Teslas have 400V battery packs. Our EVs have 800V battery packs. kzbin.info/www/bejne/sInQZnaDZrCkrq8#

[@JRL244]

kona not affected?

[@TheIoniqGuy]

Nope

[@MAGApepe]

i would hope the 2025 have all the fixes already ... they need to put a small lithium 12 v like the size in a tesla in all their cars ,, having a lead acid starter battery is just dumb

[@svenskenh644]

What about Europe!?

[@TheIoniqGuy]

European cars don't usually get their recalls till a few months after other markets.

[@svenskenh644]

@ thanx

[@BernardMaltais]

Why can't they figure this out via an OTA and only send cars that can't be fixed with an OTA to the dealer... Is it just me or is this prehistoric?

[@toddhutchins2492]

Do you really want to be driving down the road when an OTA fix comes in for your motors? I can see all kinds of issues with that solution.

[@mavelous1763]

Does the 2025 ioniq 5 use a DIFFERENT iccu? Why the heck don’t they install an agm battery (at least as a factory option) Stupid. Hyundai Kia have a horrendous history of recalls…. Not good

[@toddh4491]

This is bullshit. I love the car but this is very frustrating. Will the new ones be free of it? I already have my appointment on Wednesday morning. I've never had any issues with the battery so part of me feels like just letting it go.

[@911_dan2]

There are multiple reports of people with perfect cars having problems after the "fix"

[@ev_kimchi]

@@911_dan2 that's not true, this newest software has been only out for 7 days

[@ev_kimchi]

you'll probably get stranded if you do. Your car gives no symptoms (or, at most, you see your 12v die) before it craps itself to a stop.

[@lanceareadbhar]

Only time will tell if newer cars will have it fixed permanently. I understand the frustration as I've had two different an Ioniqs since December 2021 which have all required a visit to a dealership for the update. I even got the 2024 Ioniq 6 as that was marketed to have more OTA capabilities assuming that I wouldn't need to go in for these updates anymore. The chances of failure are still very low compared to the amount of EVs manufactured and this is my only complaint so in another sense I feel very lucky that this is it given that it is always a crapshoot when buying a 1st generation car.
