Had my car since christmas -21. Happened to me last week for the first time whit this car. Dealers wanted me to send it in but I known about this since my first ioniq. Figured it would be worse whit this one since it has the bluelink app so I already had the portable starter in it. Will receive the 2023 model in december and when asked they didnt know if the problem would be fixed. We shall see. Edit: fun fact. I had a new update when i got it running again. :)

"The Ioniq Guy" videos are awesome. I used to watch so much content about this car from MANY KZread accounts. Now i just watch 3-4. "The Ioniq Guy" included. Great videos and keep up the good work!

Wow, thanks!

Thank you for voicing your irritation about this! I'm a fellow Kona Electric owner and have had this issue several times already 1 year into ownership. Incredibly inconvenient and frustrating. To top it off, the dealership doesn't seem to know what the culprit is either.

Thanks for this useful and practical video. I just took delivery of our 2023 Ioniq 5 AWD SEL, and had seen other posts about the 12V issue, so also picked up a portable charger, just in case. I will post if and when I experience this issue.

Hey! Thanks for your video. I bought my Ioniq 5 in November 2021 in Germany. First time I had this issue with a complete dead 12V battery was about a month later and since then on a regular basis (probably 8-9 times within 2022). I called the Hyundai assistance here in Germany as it is their job to get the car running. I brought the car a couple of times to the dealer and they changed several things like the loading flap and the chip which is controlling the loading flap. Nothing ever solved the issue. Last time I picked up the car from the repair shop a couple of days ago and guess what. My car is dead again. The car itself is great but with this issue it is unacceptable to keep it. And to be honest, it seems that they are completely clueless. I will call the assistance again and will let it tow to the dealer one last time. If they can’t fix it now I will leave it there and will ask them to terminate the contract so that I will get back my money. It is really a shame. Cars like this pretty much forcing everyone who wants to buy an affordable electric vehicle to go to Tesla. I have no problem with having a car which has an issue and needs to be fixed. That can happen to every brand and every product. But having this issue over a whole year, missing important appointments, investing time to bring the car to the dealer and picking it up again and again without fixing the problem is just so annoying. These are just my 5 cents on this topic from Germany. So it seems to be a global problem with this car… Best, Ben

Can I suggest that you keep your Battery Jumper in the glovebox. As you drive the glovebox gets as warm as the cabin. I put a recording thermometer in my frunk and it only got a couple of degrees above the outside temperature during our recent cold snap up here in Canada. I expected more considering the front motor is underneath it. At least in the glovebox the lithium based jumper gets warmed enough preserving it charge over time. I know that last winter I kept my jumper in the trunk of my daily drive Toyota sedan. In two months, December and January it went from 100% charge to 25%. For February and March I kept it in the cabin and it stayed over 75% charge.

Corbin, thanks for putting this out there. I couldn't get as many views as you and I'm glad it's out there! My car is going to Hyundai tomorrow morning and I will keep you posted as soon as I hear back. I hope we don't have a serious problem but I hope this gets resolved soon.

Hi Ioniq Guy. Really good you are bringing this issue up. I have a Kona electric 2020 and my first experience with a flat 12 volt battery was about one year ago. Just now I had a flat battery twice within 3 weeks. Once in the wash hall and once in my carport. Even it's the cold season in Denmark and I usually only do short trips during the winter. I'm happy for the free Hyundai roadside assistance but it's really annoying and not an issue you should experience in a modern EV.

The day I brought my new Ioniq 5 home a couple of days ago, I explored the cab interface while it was charging in my driveway. I think I remember the display warning me about draining 12V but the message didn’t sink in. I left my car unable to turn it off, and I went to bed. By morning, the car was unresponsive. Your boost/jump suggestion resolved the problem, thankies!

I bought a 12v jumper before I even got the car. 3 months in and no issues yet but at least I have a backup. Thanks for bringing this up

Another great clip Corbin! I ordered a NOCO jump booster a few days ago and it arrives tomorrow. I haven't had the issue myself yet but I have noticed my 12v charge light is on more often lately. I also messaged Hyundai as to why they pulled the latest software update without any explanation or date we can expect a newer build. They haven't replied as yet, surprise, surprise.

I almost got a Nocco but I just couldn’t justify the extra cost. They are a name brand though so I would imagine it’s a good product. I use their 12V charger for my mower battery in the winter. I too have noticed mine on more than usual.

I've owned a 12 volt jumper battery for years, I don't remember why I bought it anymore. Always plugged in. My Bolt EUV was bought in July and we're only beginning the cold months now. I'm in Wisconsin so this will be interesting. Thanks for the video.

Thank you for the information and advice. I have an Ioniq 5 that I received on lease end of April this year. Even though the weather has been okay so far I have seen a low battery warning for the Auxiliary battery perhaps a couple of times. I haven't had any problems as of yet and hope it stays that way. Though, living in Wales it is now getting colder and I am leaving for a two and a half week holiday. I plan to charge it before I leave and see how it fairs. I will update if anything is wrong on my return.

Hello Corbin great info thanks , I still don't have my Ioniq 5 maybe not until Sept 2023 , I was very lucky and got a Genesis GV 60 , I just did a long trip here in Canada lot of snow and -8c ( 17f ) I did see the little red battery light come on when I was parked waiting for a ferry the car did tell me to start my car which I did so far I have not had any problem but I am going to buy the 12v booster jump start.. I did notice on the trip that charging in the cold weather was taking twice as long also 20 to 25% range loss. Thanks again.

Yesterday I just canceled my reservation from May of last year for the limited version. I just leased a 2023 Kia Niro EV wave for 3 years. Sorry Hyundai you missed out this go around. Great videos. Thank you

Wow... my PHEV 2019 Ioniq has this exact same issue.. and I bought the exact same jumper.. haha. Good to know when I upgrade to an Ioniq 5 I'll still get some use out of it! I did notice it's only after longer than usual drives. My Hyundai dealership has no idea why it happens. Thanks for the video.

Thanks so much for this. I live in Iceland, so temperatures are an issue. Luckily I have indoor parking; at home, overnight, but still have to have the car outside for most of the time. After having seen a video about this issue early on (I've had my I5 since March) I bought a battery monitor and a portable charger and at least that helps me worry less, but this is, as a you say, a massive issue which Hyundai needs to sort out pronto and also be upfront with their customers who have invested a lot of money and faith in their product.

I am now at 18k + miles in my ev6 3 long range drives zero issues. I have a gt-line awd. Has been from CT TO TN, FL, Ashville NC. I have a adaptive smart charger that I plugged in last week that showed the battery to br 99% efficient still. I also barely ever see the yellow light on as well. My model y went through two 12 volt batteries and was always at the shop.

No problem with my EV6 after 3400 miles! Thanks for the good information!

Thanks this bring issue back. Just got issue today. Canada I5 RWD. Latest firmware. Under 30% of charge last night, plug all night, at 80% after boost it. Big flashing message in the dash that the 12v battery are low, meaning that we have sensor but something wrong between the large battery, the "converter" and the small battery.

in November, I had the same issue twice in a week with our 2020 Leaf S plus. Dealer was clueless. The was a drain coming from the battery, and it was down to about 7 volts. I disconnected the negative lead and charged the battery with a nico 3.5 amp smart charger, and then had it on the battery condition mode for the rest of the night. So far so good.

Fairfield Connecticut. Bought in January 2022. SEL rear wheel drive. Over 17,000 miles driven. I have seen the light on - on the top of the dash. I have never had any issues with the 12 V battery. I find myself topping off the car and hardly go below 30%. If I’m at 30%, I’m usually heading towards an EA DC fast charger. I have driven up (and back in the same day) to Mount Snow three or four times last winter and immediately plug-in and then go skiing. I may have 30 to 40% of my battery when I arrive and 65 to 70% when I head home after skiing.

Thanks for providing the simple solution to this problem. I didn't realize you could cause this problem yourself. First day at the campsite I turned the car without hitting the brake pedal (I think this results in Accessory mode). I pulled out a small air pump and started filling my air mattress. When the mattress never seemed to inflate, I took a closer look and found a large hole. Found a patch and waited about an hour for the patch to set. Then continued to successfully inflate the mattress. At the end of all this I when to turn the car off and found the battery completely dead. Of course I should have put the car into Utility mode but when I started all this I thought it would be a quick inflate. I had watched this video months ago but had forgotten to take my jump starter with me (it's in a older car that needs it regularly). I walked to a nearby store and purchased a Noco 1000A jump starter. It was either defective or too small and wouldn't start my car. Borrowed a neighbor's Schumacher 1500A jump starter which worked first time. The car seems fine now. I'm hoping I haven't done any real damage and that this won't happen again. But just to be sure I went to the local Walmart which had the same jump starter on the shelf with no waiting for delivery for $99. Thanks for this advice.

I’ve had my AWD Limited since April. I live in Massachusetts. No problems so far. I did buy the jumper when I bought the car just to be safe.

I had a KIA EV , I loved the car, I set my shop up to handle a level two charger , plus my home garage . Did some charging experiments, meaning I read every thing I could find and came to the conclusion the best charge was about 80 % . This to save the battery life . I charged to 100 % one time and it showed a Range of 315, I have a picture of the dashboard . So I decided to take it on what I considered a long round trip . 120 miles . When I came back, I think I had over 30 % left . I plugged it in over nite and bought it up to 87 % . The next morning the 12 Volt was dead. This was the second time in 1200 miles . I called KIA corp and had it flat bedded in. The Second time . I had the booster you showed, but when a new car is under Warranty, I will not touch it .The dealer had it for about 5 days and when I returned to check the status they had it parked with a big booster on the back seat. I decided, that was enough of an experiment with EV's for me, I traded it in on a Hybrid, which I am very happy with . Being a very technical person , who worked on Electronically controlled jet Fighter engines, I am curious to find out where the fault lies , is it a relay hanging up, or some other Gremlin in the soft ware . Again, I am just curious, because EV's are going to be the answer for people that can afford two cars . One for around town and one for long trips. I liked running on energy from my Solar panels and passing Gas Stations, and I was set for this pattern, but it did not work out . I love the KIA long Warranty ! Other then this little problem I think EV's will work well in the future !

I have no accessories plugged in and I just experienced this after I was at the charging station the car was at 96% when I unplugged. I stopped to run an errand before going home it didn’t want to start and after a few minutes it started and now that I’m home it won’t start at all. I’m going to get an Uber to go get a 12v charger. Thanks for the video.

Hi its Omer here. My 2022 (Canadian Long Range preferred) Ioniq 5 died on me on a short drive home and I remembered your videos as the issue was the 12 v battery. Along came Hyundai Roadside assistance and gave it boost letting vebiclenstart and get me home. Now its family day coming after a Sunday and dealerships closed.till Tuesday. So will take it to local.(Canadian tire shop) and get new battery installed tomorrow rather than wait for Tuesday and take it to Hyundai dealer. What gets to me is that on the plug in charger car refuses to charge beyond 69 percent where its been stucknfor 2 days since problem occured. Was expecting this problem with dread and finally its my turn. Looking forward to getting battery changed and moving on.😂 Your work is the best out there in my opinion for the Ioniq 5.

Thanks for the heads up. I fell in love with the Ioniq 6 and was going to trade in my Hyundai Tucson for one but not now. Who needs this crap after you pay upwards of 50k. That plus lack of charging infrastructure, I'm hanging on to the Hybrid until at least 10 yrs more

2022 Ioniq 5 Boston area owner here since April 2022. Car has less than 9k miles. My car has been at the dealership for about a week and a half after getting an Electrical Vehicle System error and 12-volt battery icon error. 12-volt battery was dead and the dealer ran some updates to try to resolve the problem but now have to go back to Hyundai to possibly replace the 12-volt battery and high voltage battery. I loved this car and hope it can be resolved!

Thank you for this video! About a month ago my 12V died. Daytime and 80's for weather. My only device is a Thinkware dash cam plugged in through the OBD but have it set to avoid excessive drain. I've owned the car for 6 months. State of charge was 73%. I used the fob to unlock the car, which worked. The seat moved forward when I closed the door, turned it on and then no juice. I have an appointment with the dealership and I know it won't go anywhere. I bought a portable 12V battery charger shortly after I purchased the car that I keep in the the frunk--worked like a charm. I thought I was crazy when the 12V died.

@@kayoung604 hi! any update on your 12v issue?

After 18k kilometers this finally happened to us. We plugged in on a Friday evening, forgot to unplug, and the battery was drained a couple days later. So I'm guessing it was the state of charge lights that drew the battery down. This is consistent with the solution suggested by others of putting a small felt pad on the little button that closes the charging port. In other words, it seems like that button is also a physical switch that turns off the state of charge lights when the charging port cover is closed, and it doesn't always get depressed enough.

Couple weeks ago my EV6 turned into a log. Nothing. Both AAA and Kia were called. AAA came first and at the time I didn't know how to use the key to open the car door so I could pop the hood. Tried the key in every which way but right. AAA put the door pump and the long wire to open the door. Popped the hood and he said he didn't know about electric cars! He began to try and rip the frunk out! I stopped him and showed him how to get to the battery. He jumped it and the car started immediately. I called Kia dealer the next day and they got me right in 2 WEEKS LATER! Oh well, no problem in the 2 weeks and finally got in. They couldn't find any cause. Wow. They should teach how to get the car open as there is a procedure with the key and time! Crazy. Thanks for your video!

I live in Europe and my HI5 has gotten a battery update/charge port update earlier this year. The problem usually is the chargeport door. The car thinks the flap is open and keeps giving a 'close' command and that drains the 12v battery.

Hoping neither car will have this issue because we live in Canada & it's cold 9 months of the year here. But I guess we should grab one of these jumpers just to be safe so thanks for the heads up. Hopefully Hyundai/Kia fixes this for existing owners and removes the problem in future models going forward.

I bought a jumper cable/ battery that I keep in my frunk just in case. But it certainly is unfortunate that we can't let the car be overnight and under 30% for fear of not being able to get going next morning. My other concern is that I will soon be doing an international trip and will have to leave my car in a cold weather airport for over a week. I guess I will make sure it's fully charged and that I also have my battery with jumper cables fully charged.

i have a 4 month 2023 Ioniq-5 that just started having a dead 12v battery issue requiring a tow back to the dealership. I just bought the charger since i cannot continue to call for a tow- just like you said, it is extremely frustrating. Yes, with the original dead battery 4-days ago, i did have a Nexar camera connected to the USB port underneath the dashboard and a IPhone cable to use with carplay. Since the first episode, i have removed the two products. However, this morning, once again, the car was completely dead.

Owned mine since February in Colorado, no issues with the 12V. AWD SEL. I carry the battery jumper just in case. I have had no issues with the car whatsoever, save for the recall that was fixed very quickly.

Parked the car at 70% charge. When she went to drive it again at 4:00, it was totally dead. I have a power pack that I have stored in the engine compartment in case this happens again. The only recent change was that I installed a level 2 charger for it about a month ago, but that seems unrelated. Thanks again for the video. Gives us an idea what’s going on….

OMG - I have experienced this three times in the last week! Each time my battery if over 50% charged. I am SO glad I made the small investment in this charger. Thanks for the recommendation. BTW - what is the current software? You mention an update pulled. Any news on when OTA is coming?

I haven't had issue with the 12 volt battery so far. However there is a light with turn on yellow just behind the infotainment screen. I have seen this light on a couple of times when the car is parked that means that the high voltage battery is charging the 12 volt battery whenever is necessary. you could at least assume that charging system is actually working and is just the battery which is bad. you can find this information in the owner manual.

This issue also happened to the 2020 CX5. Mazda issued a TB, but it took several weeks of Reddit posts before it was issued.

Fingers crossed it has not happened to me so far. I notice the amber light on top of the dash being on often. Buying a portable USB 12V jumper is a must-have for Ioniq 5 owners which I bought in April after hearing about the issue.

I’ve just started having this issue with my ‘22 EV6 about a week ago. I took it into the dealership and they tested the battery and the battery tested good. My advisor suggested that next time it happens that I should have it towed to Kia rather than jumping it and maybe the battery would test bad, then, but it sounds like the battery itself isn’t really the issue so much as how the car manages it, so I don’t know if that’s a good idea or not. My dash cam is connected through the rear view mirror just like yours is. I do have LED accent lights connected to the 12V power port, but that shuts off with the car, so that shouldn’t be a problem, unless that port can somehow become active.

On my 2022 EV6 w/tech (Aug. 2022) there is an orange light on the dash that comes on when it's charging. The manual says the light is a warning not to touch the orange wire under the hood as it is activly charging from the high voltage battery. We sometimes park it by our front door and I see the light on fairly frequently like maybe every 3 days or so. It's been pretty cold here at night, @ 20 degrees F. That may run the 12 volt down quickly. We've only had it 4 months.

I continue to wonder if the UK BMS update described in the MrEV video made by Andrew Till (mentioned by one of the other viewers below) will ever be available in the US. I have raised this question on the I5 forum and been told by another owner that it's not necessary because US cars already have it, but frankly I remain skeptical of this as we continue to hear reports of this problem in the US.

They wrote back that the BMS update is only applicable to cars with a battery warmer... (Mine does apparently not have it) This kind of contradicts @Andrew Till / Mr. EV, as it points towards that the BMS update does not address the 12V issue.

Andrew Till's video did show, IIRC that after this update his 12v was getting topped off much more often, so I'm not sure what to believe. It's interesting that you were told the BMS update only applies to cars with battery warmer. In the US, I believe early MY22 only have a battery warmer (although maybe it's called a heat pump over here, I'm not sure if there's a difference?) if they are AWD. So, does that mean that RWD cars (like mine) do not suffer from the 12v drain problem because that BMS update does not apply to them? I would be interested to learn if any US RWD owners have had the 12v drain problem.

Thanks for your videos. I am on wait lists for a Tesla Model Y and Hyundai Ioniq 5. I was leaning towards the ioniq after Musk went nuts. Now I just don't know. Prob take the first one available.

The 2021 Kona I recently bought has the 12v battery problem. The 12v has a 400 crank power level. Too low for what is needed. Here in B.C. the local auto parts shop found that a local distributor now has a 600 crank power battery that is the same physical size as the current 12 V battery. So I bought and changed. Vamos a ver!

I got a Ioniq 5 AWD Limited in February, and my car started having the dead 12V battery issue in early Nov. I took the car in early Dec for repair, they said the battery sensor was bad and draining the battery. They said they did a firmware update on the sensor and charged up my battery, but I had to jump the car again after 4 days. Fortunately I have a battery powered jumper so it's just an inconvenience of starting it up in cold weather. Taking it back to the shop again next week.

Had mine since April in Utah, no issues so far.

Thanks for raising this issue, my 2022 Ioniq 5 I bought in March 2022 has had this issue. I noticed the dash light being on a lot for a day or two and then the battery went flat. A few weeks ago I noticed it happening again, the light was on a lot out of nowhere, and so I disconnected the 12v battery and let it sit for a few hours, then the next few days/weeks the light hasn't come on hardly at all. I think the issue is something electrical is doing something faulty and drawing too much power at times and the 12v recharge can't keep up over a period of time. I have heard it might be the charging flap servo/motor, or it could be bluelink.

Mine did the same. It’s been in and out of the shop. First time took them 2 weeks and they changed the 12 volt battery. I took it back the next day after I diagnosed that the car was not charging the 12 volt and there was a serious drain coming from the infotainment. The car charged the 12 volt so often burned out the regulator between the two batteries. They ordered the part but still can’t identify the drain. It’s now been in the shop 2 months. Hyundai seems super incompetent with this issue. Makes me very concerned when I have the next small problem like all cars do. I can’t be out of a car for months. Luckily they have provided me a loner car at no charge so that is appreciated.

Just had this issue too on my 23 i5 less than 5k on it. Orange light be on every hour. Charge for 20 mins turn off and come back on 30 mins later. I was concerned that it would cook the 12v battery so I disc neg cable let it sit for about an 1hr. Resetting the battery seem to have fixed it. Orange only comes on once per night now like usual.

I have the Torque app with an OBD dongle plugged into my Ioniq 5 limited. One thing I noticed is the car charges the 12v battery when I turn the car on, however unlike a gas powered car, it does not keep charging. I'm assuming after it sees the 12v battery charged it turns off. I can see this by monitoring the 12v battery voltage. It rests at about 12.1v, but goes up to a little over 14v when charging. The 12v battery also goes up to 14v while charging the car. I'm hoping mine is fine, but I also have an emergency jump starter.

You've solved the Ioniq's issue. The traction battery stack as well as the 12v battery needs to be charged, when the traction stack hits 30%. 1. If you're charging at a station and you're below 30%...connect your tag a long 12v battery pack, while you charge the traction stack. 2. If you're at home and the stack is at 30%, connect a trickle charger to your 12v while you charge the traction stack. Just make sure you have a trickle charger that can charge both an AGM and a STD 12 v battery.

For what it’s worth : on the Ioniq 1, I had the case where my trunk was not closed properly, and at the same time I did not lock the car (cause in my garage). 3 days later dead battery. I learned that if the car is unlocked (on purpose or not), or even if the charging pistol cannot lock (frequent issue on Ioniq 1), then the main battery stays isolated and no charging or 12V recharging can happen. I would suggest you guys investigate the dome lights switches + door/trunk switches.

My car has done this once. The battery was maybe around 15-20% when I went out of town in our other car and left my ioniq at home. When we came back after 3 days I went to go somewhere in the ioniq and it was completely dead. I freaked out because I had not known about this issue and it was very concerning. I couldn’t get the door open to do anything. Finally found a video and used the actual key. Then I jumped the car off from another car which was very inconvenient. I think I’m going to order one of these chargers today to have in case. I’ve had around 6 Hyundais since 2009 and they are great cars and warranty’s have always taken care of me. I hope this issue gets corrected. My ioniq car blows me away every time I get in it and has made me electric for life. Thx for video and keeping us in the know!

I have the car for over a year now (drove 36k km), and since 3 weeks i have this problem aswell. Happened 3 times already... Nothing plugged in. Time to buy a jump start, because road services are getting tired of me xD. Thx for the advice.

Happened to me too! Please take it up with Hyundai

Haven't experienced it myself, but I do see the orange light come on a few times. I checked the V using Torque and it seems that the car lets the battery go down a LOT - down to 12.4V, which is pretty low for a 12V agm battery. AGM batteries tend to die without much warning, so it could be that the car cycles these batteries to a low V too many times until they give up the ghost. Which means that a) the car requires a lot of battery power when parked and b) a bigger 12V battery should be fitted. Most likely, a drop-in Li battery replacement will do the trick, which is something I've been considering if we end up keeping the car (if we get preconditioning update).

Ne aware that a lithium ion battery is not good at dealing with sitting at 100% and all environment conditions. It may die even faster in the end

Had mine for under two weeks and it happened. Yes, I only had 30 miles but was staying in London for 3 nights. Went to car and it was dead. Good to know that basically I should always top up

I’ve had my I5 delivered last December up here in BC Canada, it’s been an ongoing issue that I see the yellow light on. I hardly ever use Bluelink since the app is so buggy even with the refreshed update. Going in for EV service # 2 next month will let the dealer know

2022 Ioniq 5 owned since last January. Just started having some pretty serious 12V issues...Even when my car is fully charged, it isn't topping up my 12V. I clearly have a short or phantom load somewhere drawing power from the 12V (probably from my new trailer wiring) BUT it is not being charged by the larger battery.

This was a problem with the first models were they had a defective charge port door. They replaced it and it solved the issue. Newer cars don't seem to have this problem.

I notice the dash charging light often coming on in my garage. The ioniq 5 must have a significant electrical load when turned off. I wonder if anyone measured the current at the battery?

Happened to me here in the UK. Parked the car with 16 miles left for a couple of days and then it needed to be jumped. I thought the issue was fixed with the software update as it’s only a couple of months old. Obviously a bit shocked that it’s still happening. Got a battery monitor and jump starting kit but clearly we shouldn’t need to be doing that! Love the custom number plate by the way :)

Mine did the same. I’m so surprised as hi-tech as this car is that it won’t give a warning that you will be stranded as the battery slowly trickles down. I just bought the monitor for the 12 volt.

Data Point: I've never had this problem I hav had my LR RWD since December 2021. Never had the dead 12V issue. I travel for work and will often leave the Ioniq 5 in the driveway for a week or more with the state of charge under 20%. I am in southern British Columbia so we don't get crazy cold temperatures but -10˚C is expected during January and February.

I have a 2022 Kona EV and am having the same problem and share your frustration. My problem is compounded by the fact that the system starts throwing error messages at me so, for example I can’t shift the car out of park, etc. it has happened 3 times. Summer Fall and Spring. Note. If you do get the car started via a jump, drive it for at least 30 minutes. Don’t just let it sit on because that doesn’t do any good. Dan S

Keep a schedueled pre-heat of the car. When it warms the cabin it also charges the 12-volt battery it seems. Since I started doing this i've had no issues.

Pretty sure that preheat function only uses the 12v battery. Any of the remote functions do. I avoid doing it because if that.

I don't yet own an Ionic 5, but I couldn't help but notice that Erin had a couple of things plugged into the USB sockets. Are the USB sockets live when the car is off? Also you said that you don't have any accessories plugged in that would be draining the battery so that there's no reason why it should be happening to you and it hasn't happened to you, right? There has to be a cut off point where the main battery stops charging the 12Volt, otherwise it is likely to completely drain everything in potentially the middle of nowhere. Perhaps there could be an emergency override option to charge the 12V enough to start the car?

I have had two similar incidents with my Kona. I found out that it was because I was not closing my tailgate properly and the trunk light was staying on. Since I started checking the boot was closed properly every time, I have had no further issues. I had already bought a 12V jumper battery though after the first 12V battery failiure.

I picked up my 2022 Ioniq 5 Ultimate in mid February of last year... I've never had a single problem with the vehicle since I picked it up and I now have almost 50,000km (31,000 miles) on the clock. I'll keep my fingers crossed that I don't run in to this issue.

Many thanks...going to pick up my power station

Happened to my 2021 model for the first time a coupme of days ago. I did run the car down to 13% charge at the time i parked it up. Next use was 2 days later and it was completely dead. Had to boost the 12v battery and then sit in the car in the driveway for 40mins or so to get a decent charge to the 12v. Was well above freezing out @ 9 celcius.

Hi Guy; Steve here from Seattle. 2022 Ioniq 5 SE that I just purchased 10 months ago has dead 12V today. Hyundai Road Side assistance (sub contracted with AAA) is on their way with 1 h eta. It's 45 deg today, the car was down to 11% on the main battery so I suspect that my short drives the last few days were not charging the 12V. I've not had any accessories going other than my phone was plugged in for charging yesterday, only while driving. Interestingly, my wife and I noticed the last couple of days that the heater blew cold air at first, then would act normally after turning it off and back on. Think that should be run off the main battery so not sure if related. One final thing is that the light bar above the rear hatch back is lit up. Doors don't work, hatch won't open, charging door won't open. BTW I have both jumper cables and a portable starter like the one you have, sadly they are in my wife's car who is not available to help for a few hours. Thanks for your continued work on all our behalf. Steve

It’s happed to my wife several times recently during a road trip. Fortunately, I bought her a portable battery charger weeks ago. Hyundai definitely needs to figure this out!😡

I took delivery of my Ioniq 5 on April 1, 2022. I have not experienced any problems until this week. Two days in a row the car failed to start. I was able to jump start the car with the portable charger. I took my car to the local Hyundai dealer. They contacted Hyundai Tech Support because all their tests showed the 12V battery was working fine. Tech Support told them I needed a new battery supply management module. It was ordered yesterday. In the meantime the dealership loaned me a 2022 Santa Fe as I told it could take a week to get the new module. I live in South Texas and the weather has been in the 70-80°F.

Ioniq 5 since May 2022. 12v battery kept dying the past month (Dec 2023). The first time I brought it in, they couldn't replicate the issue, but they tested the 12v battery to be good. They told me to tow it back when it dies again. It died again three days later. Had it towed in. This time they said "since you brought it in dead, the 12v is bad. Our test equipment says to replace the 12v". It'll be $200 to replace... No thanks. I'll replace the battery myself. Haven't had time yet, but gosh, I wish we could all do some kinda class action lawsuit against them. Thanks for this video. Gonna see if keeping main battery above 35% will keep it alive.

I had this issue this week. I live in Norway. It has been cold (-10 deg c). Left my car overnight with 15% battery after long trip. 12V battery was at 6V the next morning. I had to remove and charge back up. Seems to be ok now. I will not be leaving car with less than 30% charge in future. My big concern is that lead acid batteries don't like big discharges - so could be damaged now. Considering switching to a lithium ion 12v...

23000kms, 2022 ionic 5, 9 months, no problems. I keep my car cycling between 30 and 80 percent, don't use the app, don't leave on while parked. I did purchase a 12 volt jumper just in case. Hope this is solved for all of us.

I had a dead 12v battery in my Ioniq 5 about 2 months ago. Jumped it and recharged it, and back to normal, but that battery drain came on fast. I did some digging and found some having battery drainage with the Blue Links app (checking battery status over and over). I know it sounds odd, but the app checks the car from the 12v, so I don't use the app or the widget anymore. We'll see if it helps.

Hello! Have you had any issues since?

ive had mine die once since i got it in april. got jumper from amazon. before it happened so i was lucky. I saw it happen to out of spec so i snagged a 50-60 dollar one after I saw that video

Have you tested the health of your current 12v battery. They need to be changed every 2-3 years in ICE vehicles too. Getting a better quality battery may be a good investment.

Yup, having same problem, but with the new (2024) IONIQ 6. 3rd occurrence now. Guess I need to purchase the jump starter to resolve. Hyundai dealer seems clueless on how to fix this, and no software update is effective. Like you, LOVE the car, hate the inconvenience.

Oh no! I think you’re the first GV60 owner I’ve heard of this happening to. Going to bring it to the dealer or whats your plan?

I have a 2022 Tucson PHEV and worry about this since I’m in Canada where it gets cold. The 12v battery is located in the rear under the cargo mat so accessing to boost or charge isn’t easy. There’s an escape mechanism to open the rear hatch but you need to open the front door and crawl in, etc. After 12 months I have not had a problem with not starting but would like to know how we can avoid this and if the Aux Battery Saver + is sufficient to keep the 12v battery charged.

Had this issue in Germany with the 22 model after 9 months on the 23rd of December for the first time. Battery level 80%. 12v battery low at 3.9V. I have the newest software update from November 22.

Thanks for this heads up. My Ioniq5 is 2 months old and the range has reduced from 290-210 miles. The car goes into the dealership next week.

You would have thought that having sold these cars for two years he would be more knowledgeable. I am buying a 12 volt pack in expectation of further problems. Shame because I like the car.

We purchased a portable jumper shortly after purchasing our I5 last February. So far we have not needed to use it. We haven’t left it sit below 30% SOC so maybe that helps.

I have an EV6 GT Line AWD. No such issues yet after 4 months. My car rarely goes below 30% though.

Hi! Was your 12v issue fixed?

Just happened to me. I have a 2022 - coming up on 2 years in March. I also bought one of those portable jumper things, but it didn't work. I guess my battery was too far drained. So I plugged my battery into a trickle charger, and it was charged in about an hour or less. Wasn't having an issue until just now... I just got it back from the shop about a week ago where they did the recall/upgrade stuff.

same issue with 16' ford focus electric. only problem we've had. it's plain stupid. wish Hyundai would get this right. so much to like in the Ioniq

I had this issue in my 2017 Sonata. I had to replace 3-4 batteries in a summer. There was a low voltage draw from the media center.

I got my IONIQ 5 on May 30th, and just recently started having this problem where I get the battery EV Indicator. Usually it happens if I don't drive the car for a day but today it happened while I was at work and I had driven the car that day. I do notice that the EV battery is still at the same charge %. I have an appointment but I get the feeling they won't have a solution for this. It's very frustrating.

Is the DC/DC Charger a discrete module? or part of a larger(and more expensive) module?

Curious if any specific trim is experiencing this.

I also have a 2022 I5 Ultimate in Canada. I did buy the portable jumper about a year ago, but fortunately have not had to use it yet. I have, however, used it twice to assist neighbours with their ICEs and once, with my second car, that is also an ICE. QUESTION - Is it true that the big battery does not charge the small battery while the big battery is being charged?

I had this same issue with my Canadian 2020 Soul EV, even brought it in after 6 dead 12 volt battery events. They would check the battery and it was fine according to their tester. I just went out and bought a good qaulity AGM for 1/2 the price that Kia would charge for their suspect quality battery, been working just fine at over 1 year never dead!
