- Hyundai saw my previous video about the 12V battery failing and got me into the dealer. They worked some magic and all is now good. I think!
One cold day early in 2022 I came out to the IONIQ 5 to find it wouldn’t open. The 12-volt battery - the bane of my life with my old Kia e-Niro - had drained. Video here: • IONIQ 5’s 12-volt batt...
Thankfully I got the car going again using my trusty portable car starter but I was completely baffled as to how it happened in the first place. This video doesn’t answer that (as I still don’t know) but I’m confident everything is now fine after getting a BMS update from Hyundai.
I’m confident it’s not going to be a problem again. Proof? Get ready for some 12V battery graphs thanks to the battery monitor I installed in this video: • Monitoring the IONIQ 5...

I always think of things to say after I’ve finished editing the video! Obviously there’d be less strain on the 12V if we just didn’t use “Approach Unlock” (or welcome mirrors as I insist on calling them).
My wife likes it, which is why the setting has remained on all this time!

Thank you!
I had a problem where the 12v battery was flat 3 days running I sent the car back to the dealer they found the fault was with the charging point ie where you plug bthe charging into the car had to wait over 2 months to get new parts for the charging point to be replaced so please tell your viewers it could be charging point on the car.
@@seanholdom9739 mind sharing some more details? How did a faulty charge port result in a drained 12v battery?
My ioniq5 was delivered 5th of may 2022 . Today I had a recall software update and asked for BMS update as well as you said . The answer form Hyundai was this car does not have/need a BMS update , it looks like it was up to date already !
As a software engineer, I'd like more data on what its doing to make its charging decisions. Looks as if they've taken something out of the algorithm so that it charges more often but its not obvious what the criteria are. Still, thats just me. My dad used to say "The more things you know, the more things there are to worry about". :-))
Some software engineer you are, eh? It's obviously a watchdog timer with a threshold for battery voltage on fixed timer, like every 10 minutes for example. That's why it may look sporadic, because it skips some cycles when the voltage is just above threshold and on the next cycle it's just below the threshold when it decides to kick in.
@@1sword4you LOL. Possibly correct. Mind you, I wouldnt have done it like that
Lovely to get a video!!! I was really looking forward to my ioniq 5 arriving in September, but have just been told by the dealer that the car I ordered and paid for last November now won't be produced and I can either get a refund or pay an extra £2500 for a model year 23 that I won't get until January at the earliest. And they refuse to guarantee the price!
Great news . Thanks for another great update video
great update, look forward to getting my Ionic 5, was promised Mid May, than July now Oct-2022 is the expected delivery!
My Vauxhall Corsa E Elite Nav has had x 2 12v batteries replaced due to going flat within last 12 month's, even though use car daily to and from work ( 30 miles return ), get ready go work like yourself and battery dead as a dodo! I've just ordered BMS kit and will put onto my car to see if can give me any ideas if problems. Wish my car had over the air updates and battery warming, but thankfully changing car next year for either Kia Niro EV or EV6. Thanks again for your informative video's 👍
Many thanks for the important advice!
Thank you for a good Chanel. Yesterday I had my ordered towbar installed - after 4 months, update on parkingbrakes, and new Maps. But update on Infotainment and BMS was not avbilde in Norway. I hope, and have to wait …
On my Ioniq 38kw had BMS updated in March. Seeing car charging battery every 4 hours. Took 2 half years for Hyundai to fix problem. Good luck with Ioniq 5
Great Video and Information Andrew..👍
I used the same Bluetooth battery monitor when I bought my second hand e-up, I had low 12v battery levels, the factory battery was 6 years old and 40Ah. I noticed the holder plate under the 12v battery had an additional metallic corner bottom fixation hole for cold climate bigger batteries option, i went with a Varta silver doped 52Ah and everything is perfect. I did replace all the incandescent bulbs 💡 front, rear and cabin, with high luminosity leds lights and I have a better night vison now, plus the added bonus of divided the consumption to 1/10th. If you have an e-up, go for it.
Fantastic! That would have made a fascinating video had you filmed it!
Agree with the battery monitor; invaluable. I suspect there is some common issues with 12v battery management but I’ve realised there are some key things that you can do to mitigate unwanted drain as you said in your video (not entirely sure why having the wing mirrors open when you get near the car is any advantage as it happens anyway when you unlock the car (which is really what you want)). I have also found when unpacking/packing out Kia Soul for long trips that the cabin and boot lights have a big drain on the 12v, so I try and keep the doors and boot open for a minimum and turn off the internal lights, which are not needed the majority of the time in daylight. I appreciate these are all things that you shouldn’t have to consider when driving a car, but are not really difficult or inconvenient to implement in practice. Sadly I don’t think this kind of update that the ionic 5 has had will be used in the older vehicles.
I use the same or very similar ODB2 dongle that you used on your UK to Italy trip in March. Although they probably don’t pull enough dark current to flatten the 12 v battery anecdotally others have had some issues. I certainly have seen the 12 v low warning in my 2022 EV6 Std Range US spec model as others have seen. Oddly my car was delivered in mid April this year and as far as I know it was already updated with all recall or service issues when they prepared it for delivery.
Now obviously Kia be Hyundai will probably have some different issues. Still and all it might be interesting for you to try unplugging the ODB2 dongle and see if it has any effect on the drain you see in your battery monitor.
Just ordered one of your battery thingies for our Kona, but not had any probs since I put a new batt in after 3 years. You were shaking a bit when you clipped it on the batt, you all right mate. Alan Suffolk
It was back in February and I was freezing! I had a mini-stroke which makes my right arm feel even colder than it should. Thanks for your concern!
Hi Andrew my Ioniq5 is in the dealership after a weekend of woe. Two AA call outs for you guessed it the 12v battery. Thanks to you I managed to get the car going with the portable jump starter. Four mornings in a row and a flat 12v. Not great for a three weeks old car and 200 miles from home. Continue your great work keep safe.
They need to do the BMS update and replace the 12V by the sounds of it. Ridiculous to have to go through this sort of thing on a modern car!
My ioniq just had a dead 12 volt battery. What is the remedy? I need to take it to the dealer to have an update? I never see the yellow charge light in the dash go on anymore.
Amazon seller put price up from £21 to £27 just after your video was released! Ended up ordering off aliexpress. No kickback for you! But have an upvote and my thanks
Blatant profiteering! Good tip to use Aliexpress.
My 12V battery on my 2023 Ioniq 5 Limited just recently died after returning from vacation. The car sat in my garage at about 79% state of charge for about 8 days. When I returned home and tried to start, it was completely dead and had to jump the 12V battery. So I guess there is still an issue going on here
Glad that you still have the I5 and not been persuaded to get a car that makes rude noises.
Great Video!!
12V battery temperature plays a role. The colder the 12V battery, the higher the charging voltage (highest in winter). Probably the top-up threshold voltage around 12.5V is also temperature-related.
Ah, very good point that seems plausible. Nice 👍
You can lock the car in utility mode. If you use the central locking whilst sitting in the vehicle, exit via the drivers door and then use the key to manually lock the drivers door the car is locked.
Thanks.
Have the same problem with my IONIQ 5. Happend last month the 2nd time since I own the car. I noticed it happens when the Main Batterie is below 20%, then IONIQ 5 does not charge the 12V Batterie, which does not make sense at all since its way too high limitation...
My Dealer doesn't know what to do and I am frustrated. I dont want to add a 12V monitor, this is not acceptable for a 50.000€ car.
If I remember you have the solar panels on the roof. Do you think the 12v top up is related to a sunny day?
I was able to copy your US link to the battery monitor. Our IoniQ 5 12 Volt is "modern" I hope... (the other choice is twice as expensive for lead acid.) You can ignore my twitter plea. Thanks for all your GREAT info!!
Great info and analysis. Curious if this has increased the standby/vampire drain of the Ioniq. I know Teslas consume a surprising amount of energy when simply parked, but EVs from Chevy and VW don’t (at least not with the Bolt and ID.4). I wonder where the Ioniq 5 falls on the spectrum? Seeing your 12V data I think it will have less vampire drain if you truly leave it alone (like go on a hike) vs if you’re at home constantly triggering the door handles. Would love to see a video analyzing this.
It barely makes a dent in the state of charge. Certainly nothing like the phantom drain in a Tesla. I'll try and do a video about that if I get a chance!
@@MrEV The phantom drain in current Tesla Model 3 is 1 percent per week, if sentry mode is turned off.
Phantom drain in my model y was about 3 to 5 percent with sentry off. With sentry on, it was about 1.5% per hour. Haven't had the y since early January so not sure if it's been improved. Phantom drain on my ioniq 5 is next to nothing.
hope i get all teh updates already installed when they diliver my new ioniq 5 in december 😉 but is ther a source where you can see all the newest updates available?
I had the same issues with my Kona EV my2021, odd from Hyundai to make the same error, again.
Just had a safety recall letter today it seems to be identified as Campaign: 21D064 and refers to a fault with the Park "P" position disengaging after being applied due to electronic priority.
So they to want apply a software logic enhancement to the vehicle shift by wire Control Unit, no mention of any other areas to be updated though I will give them a ring and inquire about this.
I looked at an Ioniq 5 a couple of weeks ago, and to show me the infotainment on the one in the showroom they had to attach a battery booster as the 12V was flat.
Oh dear - that's not a great impression!
Sei un grande
I wonder what chemistry the battery uses. Seeing the voltage step up and step back down during a charging event says to me, based on my own experience, that the battery is weak/ sulphated. Normally I would expect the voltage to ramp up when a charge current is applied and ramp down to a rest voltage when the charge current stops.
Yes, agreed. The steps in battery voltage are indicative of a battery with high internal resistance, which is not good.
It would be useful if the battery monitor measured charge and drain currents. Difficult to implement with a simple connection.
I’d suggest first checking the calibration of the BM2 against a DVM. Assuming it’s fine it seems to me that your battery is not taking the charge properly. It should end up at a higher voltage like 13 then drop no lower than about 12.7 before the next charge.
I agree completely. Though I also have to say, that kind of charging is not ideal and will probably never charge the battery to real 100%. They take some time to get fully charged...
@ yes, the pattern indicates that your battery appears to be either damaged or in need of a specialised charge to attempt to restore it.
Initially I thought the bonnet was up to protect your hair do! Like you say Battery monitors especially handy on allsorts of cars.
My hair was particularly ridiculous in this video. There needs to be some sort of hair filter in Final Cut Pro!
That's good news.
If you can find out how to tell if the update has been applied (version numbers, etc.) that would be awesome!
I show the version info briefly at 11:13 - I think they’re the latest version numbers.
My 2022 Ioniq 5 SEL has been at the dealer for the past 3 days due to dead 12v. My multimeter showed charge dipped to 3.8v but got it going with a jump pack. Seems the dealer isn't able to locate the reason for battery drain after 3 full days. They gave me a loaner so I'm not going to pressure them to fix it. I am not very hopeful at this point. I agree with Andrew's diagnosis that my BMS is most likely the problem, but the update is not yet available in the U.S. as far as I know. I've had my car for just 7 months.
Are the software updates you refer to for the UK including the BMS? Last update I did in the US was the end of May and also the Parking Brake Recall...Is OTA available in the US?
You can tell if your car is OTA infotainment ready by going into setting -> general -> version info/update. If there is any mention of OTA on the page, then your car is ready to receive its first OTA for the infotainment/navigation system. Hyundai has not yet opened its OTA to update other parts of the cars many software system but the infotainment system. This means that if there are updates released to other modules, you will need to get it updated at your dealership for now.
Why would hyundai top up the 12V battery based on the volt-reading ? Wouldnt they top up the 12v battery, instead on how much Ah or Kwh is left in the 12v battery ? And are you sure, that the battery gets topped up "without active intervention" at all ? Like when the main battery gets charged (fe at night), and the 12v battery is beneath a certain percentage of Ah/Kwh left, the battery will top up, or when you pass the car, and the mirrors fold automatically, it will check , what % the 12v battery has left, and it will top up if beneath a certain percentage ? (the idea is based on your previous vid , where you explained how to install the battery monitor, there the battery monitor showed that the 12v battery had 15% power left, obviously this didnt lead to any action of the car, until you stepped in the car, "activated the car", then it began automatically to charge the 12v battery, this was i suppose before the bms update.. but i wonder if this couldnt also happen (getting to 15% power) and the car not doing anything, after the bms update..
The ev seems to really drain the 12v battery fast...must have quite a high load on it continuously.
you can lock the car in Utility mode in Canada by using your phone App.
Andrew...has the Hyundai proven to be a good auto for your normal family life including holiday? Upon reflection, do you feel it has proven sufficient value for the additional expense. I know there was a little concern initially regarding the cost of the auto. It appears to be a very competent car.
Yes - it’s a wonderful car. Comfortable, decent range, good features, and is (I think) a stunner!
With the Model Y costing so much in the UK, I think it’s still quite competitive.
Software update needs to deal with the scary lag on acceleration when you are in sports mode. It is like driving an old turbo Saab. Also the self parking is definitely not set up for right hand drive. Asked about a software update but our dealer is only happy todo it if we have a service. I like the car but the software is pretty pants.
Since I love to drive with I-pedal, I also keep turning on sport mode to try and midigate somewhat the sluggish gas response. However I find that sport mode can make the pedal response a bit jerky at times.
Hi Andrew. Did Hyundai need to do a drain & charge cycle on the battery in order to complete the BMS update? Mine has been in the dealership today and just been told it has to be re-booked in to have the cycle done. Seems a bit odd to me, especially as it's been booked in for a while. I get the feeling they don't really know what they are doing.
Update.... apparently my car already had the BMS update prior to delivery which means it hasn’t solved the 12v flat battery on my car. They want to do a battery drain/recharge to see if it throws up any warning signals 🤷🏼♂️ I don’t know whether that’s the 12v battery or main battery come to think of it!
Great Info. I also have the same battery monitor, but when I click on the trip at the bottom, I don't get the graph but just a list of data points.
You have to click the magnifying glass icon to see the graphs.
@@MrEV Thank you!
I’ve been watching some other videos on TH-cam that have mentioned this issue. All are similar age to this video. They seem to indicate the software stops charging the 12v when the main battery is below 20%. Hopefully they corrected that in BMS update also
I’ve heard that too. What a stupid limitation! I’ve no idea whether they’ve changed it now.
Hi Andrew thanks for posting a very interesting video - I installed the infotainment update that allowed OTA software updates back in March when I got the car so I assumed that this would automatically include the BMS type updates you refer to in this video. Are you saying that this is not the case and I will still need to visit a dealer?
Yes, unfortunately the BMS update is a separate one that they don’t allow owners to do themselves so you will need to talk to your dealer.
@@MrEV Out of the blue just after I read your reply I got a recall notice from Hyundai for my LR RWD Ioniq 5 (first registered in March 2022) telling me that there is the potential for the parking brake to release due to internal vehicle electrical noise and that it needs a software update. I booked it in and they agreed to do the BMS update at the same time. What I don't understand though is what was the point in installing the OTA update in March if all the important stuff still has to be done by the dealer.....
@@Lyndalewinder This: "what was the point in installing the OTA update in March if all the important stuff still has to be done by the dealer?"
@@omelborpon3159 so what don't you understand?
Great informational video. I am have the same issue with my EV6 and have taken it to the dealer 4 different times with the 12v battery going dead. The Dealer on the second time there said it was the dealer installed Lo Jack that they installed prior to me purchaseing the vechicle causing the issue and so they removed it. I have been back two more times with the same issue and they state that the 12v battery is fine. I also noticed that the light on the dash that comes on when the high voltage battery pack comes online to charge the 12v battery when it gets low has not come on in serveral weeks so the battery just dies.
The question I have is can I use a jump pack on the dead battery to get the car going with the battery monitor attached? the last thing I want to do is destroy the battery monitor device or possible damage my battery even more. Thanks in advance for any information you can provide.
I've jump started the battery with the battery monitor attached, and it's absolutely fine.
They really should have just replaced the battery by now. I'm no expert but there could be a dodgy cell that's causing it, which wouldn't necessarily show up when they check it.
Jeez, my old Tesla (a 10 year old design now) gave me a warning of 12V going at 6.5 years old, Tesla came to replace on my drive. I nearly got an ioniq 5 after such a good experience with our Ioniq electrics, but quite glad I didn't.
I wonder if they ever found out which 12v unit was being switched on in standby mode?.... and switched it off in software?
There was a rumour that it was the charge port actuator?
I think it’s more than just one single thing. Since I have three times experienced my car switching on my driving lights while locked and turned off for hours. This strange behavior has only happened when my light switch has been in on position. I now try and keep my light switch in auto position, and the issue hasn’t occurred yet.
I live in upstate NY and bought my ioniq5 in February and started having 12 volt battery issues in June . I took it to the dealer for the parking brake update. I told them about the 12 volt battery problem and asked if they could do the BMS update. They acted like they never heard of it. They checked the 12v battery and said it was fine. I have had to jump the 12 v 4 times in the last few weeks. One time was after driving an hour to a softball game and checking the car after 15 minutes. Tow truck jumped the battery and I was able to get the car home. In any case, does anyone know if this BMS update is available in Upstate New York because the dealer doesn’t.
Think you need to quietly switch it off until you know Flaviana is going to drive the car! 😂 Go on... you know you're brave enough! 😄
Is there an app you can do it on discretely? (Or is it discreetly, I can never remember the difference? 🤔)
I'm wondering how good it can be for the 12v to be having so many charges.. but I have no idea and you're monitoring it so I guess you'll find out and it'll be fine.
Always enjoy a good graph especially when they're nice and clear even on my small mobile screen, as are yours. Good job Andrew, seems like ages since you posted. We're very excited about the new MG ZS having had a good look round and in a few EV's at Faversham Car Show a few weeks ago. Hoping it'll be not too much on the used market in a couple of years. 🤞
Thanks for update. I'm waiting for my EV6 which I will leave in the garage for 2-3 months at a time when I'm abroad. I'm worried that both batteries will drain. Is it possible to keep the car plugged into the charger to top up the main battery which in turn tops up the 12V?
Don't leave the drive battery higher than 50-80 % if you're gone for a long time, it's more wear on it if you charge to high.
It'll loose less than a single % pr week.
I don't know Kia, but we have an electric Ioniq and it charges the 12 volt when needed, plugged in or not.
@@karstenpedersen7749 thank you so much for the update
I had my car updated last Friday and they said that there were 3 updates required for my car. Electronic Handbrake, Rear door central locking and BMS. Only knew of the first one, but hopefully all good now.
Awesome. Which country, and do you have the campaign numbers for central lock and BMS. The park brake one is called 21D064.
@@vidarskre Im in the UK but sorry I don't know the numbers for them. I was unaware of them as well so came as a surprise. However, I did notice previously that randomly the rear doors would not open from outside so I guess this was the issue.
I have a 38.3 kw Ioniq, and recently I find out that if the SOC is below 30%, the car is not topping up the 12v battery. My car Bluetooth didn't work when I try to call someone, they don't hear me speaking, and the next day the car was dead. I find out that in this model this is one of the symptoms when the 12v has a problem. After I use the jump cable to give 2 seconds of power to the battery everything was back to normal. I wonder when happened to you what was your car SOC?
I've had my ioniq 5 for 7 months and 18500km. Never had a problem with the 12v.
Does this just mean your main traction battery will lose more % of charge (phantom drain) by the morning as it is now topping up the 12v battery Willy nilly? The BMS update may have improved things but still not convinced it is doing its stuff as efficiently as it could be.
That's a good point. Any drop in state of charge is pretty low - certainly not enough for me to notice. And nowhere near as much as a Tesla with sentry active, for instance!
Clearly it is good that the car is now topping up the 12V battery as its voltage degrades but I am left thinking they have cured the symptom but why is the 12v battery voltage falling in the first place. Is this level of draw normal when the car is not in use ?
my guess in blue link communicating with the car while it sits.
Any idea if it's possible to tell if this update has been applied? I picked up my Ioniq 5 this morning and the dealer tells me all updates have been applied but I have my doubts.
There must be a data log somewhere listing current status?
Then a quick check on the forum?
Can't Hyundai update infotainment system at home same as Kia?
We miss Flaviana so much
You have the P45 version with the Solar Roof - why is this not topping up the 12v battery ?
Because it will be feeding into the main battery at a far higher voltage which minimises voltage drop. Plus it is a large PV panel and would be wasted just keeping the 12V battery topped up. It is the main battery via the BMS that charges the 12V battery.
How low was your state of charge? There's a theory for USA models that if the battery is lower than 30/35%, it will not charge the 12v. Can you test this out with your battery monitor? USA does not have a BMS update like UK.
I parked my US AWD SEL at the airport with 13% charge on the main battery. I didn't have time to charge it before my flight but was only 2 miles away from the nearest charger and figured I'd be ok. Left for 9 days and returned to a dead 12v battery. During that time the blue link app was sending notifications, it seemed like every 30 minutes or so the car would connect to Bluelink. I think the blue link connection is draining the 12v battery, along with all the other possible drains like the charging door, automatic unlocking doors, etc. After jumping the 12v with a 3000 mah jumper car started up and the main battery was hardly drained, maybe 11-12%. Therefore it was clear to me the main battery did not charge the 12v as expected. I like your theory of 30/35% cutoff. It would be nice to find out for sure where the cutoff is where the main battery will no longer charge the 12v.
I guess I should get a monitor because my Ioniq 5 is 6 months old and recently (started about 10 days ago) I went to get in and it wouldn't start. So I got my trusty small car jumper out and it started right up. Then drove it for the next couple days and it was fine. Then this past Monday I went to run some errands and it was once again not starting. Jumped it again and ran my errands and it was charged enough to start after each stop. But then while I was gone my wife told me it was dead again just a couple days later
Do you have the latest update from the dealer?
Just happened to mine today after a run of over 400 miles. Mine is a my 22.5 also.
Do you run a dashcam, or any other extra equipment?
I can't believe Hyundai still hasn't fixed this flagrant issue that exists since the Ioniq EV in 2017... ridiculous...
How on earth is this necessary to top up a 12v accessory battery in a car several times a day? It's a patch over a phantom drain that they can't fix...
My local Hyundai dealer traced the issue in our Ioniq EV to the SOS module. It turned out me opening the cover (but not pressing the button) and closing it activated the SOS module. It remained active for a few days draining the 12v battery. Since replacing it early this year, we’ve not had any issues.
Hi Andrew, why i think the battery problems is from bluelink ,coz 3 times i had the battery problem it was when i was using the bluelink. What you think ?
Yes, I'd heard the same from others. It should now be fixed if you get the latest update for the car.
@@MrEV just left the hyundai garage and was no updates 😢, thanks anyway for your time and keep up your good work
I have been wondering why my vents opens sometimes when the car is parked and locked (without being connected to charger). I guess it’s topping up 12 V 👍
It shouldn't need to open the vents for that.. the 12V charging takes barely any power. More likely it's just general battery pack heat controlling due to outside temps.
@@WooShell I agree, sounds right 👍
I don't understand why they released the Ioniq 5 with this issue, the 38 classic Ioniq had exactly the same problem and the 'work around fix' of charging the battery every 4-6 hours was applied to my car back in January. Hyundai never acknowledged there was a problem and indeed actively denied it but the Bluetooth 12v monitor says otherwise. Poor customer service imho.
It's a patch, isn't it?
They seem to have stopped it discharging too far, but not stopped the cause of the phantom drain.
So Ioniq 5s without the handle feature, are they having the same problem?
Yes, all IONIQ 5s can have the same issue if they haven’t had the BMS update
Bout that usb battery pack a few months ago just in case.
I’m glad you’ve not needed to use it yet!
I think you’ll find you can lock the car in utility mode! or at least I can on my Kia Niro 4+. It’s done by locking all doors from the inside of the car except the drivers door the exit the car and lock the door with the key. There’s another blogger with a Niro who did a TH-cam video demonstrating just that.
th-cam.com/video/fUq4QtV_QNU/w-d-xo.html
Do you think the Ioniq 5's winter charging speed is rubbish?
mach-e, ID.4, IX4, enyaq is super duper rubbish?
The charging speed of the Ioniq 5 is faster than those cars in the winter.
Ioniq5 was charged in 30minutes in the winter( 10%~80%, not extremely cold winter).
Any idea if there's a BMS update for the e-Niro too?
There was an update back in late 2020 but I'm not sure if there's been one since then. Perhaps other e-Niro owners reading this might know?
@@MrEV late 2020, they just made the 20 minutes per 24h more reliable, that's about it, I'll ask my dealership if they know anything about anything more recent, though, they usually are unable to tell without plugging tools or checking up a VIN 🤷🏻♂ (just had my e-Soul serviced last week, but had a BMS glitch yesterday (empty SoC+Turtle), so I was planning to have them pull DTCs if any)
In an Ioniq 5, if you needed to leave a dog in the car for a few minutes, how would you do that and lock the door without setting the alarm off? Cheers.
I had to do that a lot recently on a trip to France on my own! Settings > Convenience > Advanced Anti-theft. You have to turn that off each time as it resets after turning off the car.
It’s clear that having to turn on the car is a hark back to the good old days of ICE car thinking.
A shame.
Good that they’ve fixed the issue though for keeping the 12V battery charged properly.
Having no on/off button makes much more sense, of course - I never turn off my computer, why should I turn off my car? - but it still feels 'wrong' to me. I'm sure if I had a Tesla I'd get used to it quickly!
@@MrEV It made sense when you had to turn the engine off but EVs don’t have an engine. :)
@@MrEV You don’t turn off your Computer? They boot so fast these days I turn off more than standby to be honest (and does save a little power
). Personally don’t find pressing a button overly onerous unlike Clive, each to their own 😎.
@@SirHackaL0t. Every advanced electronic device I own has a power button, not sure it’s solely limited to ICE. From games consoles to Apple devices to PCs.
@@alexhaddock4554 @alex When we had to stop an engine going chug chug it made sense that you need a way to stop it. So what’s the point of a start /stop button in an EV?
My car wakes up when I open the door. It goes to sleep when I leave the car.
Why do we need a button? Other than to make people less scared when transitioning from an ICE car.
How does the Ioniq compare with the e-Niro with the annoying bing bong safety features such as the lane-keep assist that you can't disable on the Niro - i know they annoyed Mrs EV in the Niro.
IONIQ 5 has just as many bing-bong safety features. You can disable it by holding down a button on the steering wheel, but it has to be done every time you drive.
Thanks for the update, Andrew. Are you a better cook than your wife? /runs
God, no! She’s brilliant - but I tend to always cook for some reason. We’ll do an episode cooking in Italy some time perhaps. 😀
@@MrEV and we'll be watching that ep too. :)
👍👍👍
Your 12V battery drops much faster during no activity than on my Prius. Probably that BMS system is fixing problems it causes in the first place. I have no top up system and the battery drops below 0.1V a day.
Good to see you back, Andrew. It's been a couple of months now! However, quite understand when you have a car with suspect software and a wife that demands you cook the dinner rather than work and earn some money!!!! 😁👍
Regarding the battery-preheating update on MY22: there is a lot of doubts about thats right, even with the eco pack including the battery heater.
- Does this recall / service action have a unique ID?
- What is the production date of your IONIQ 5?
I'm still having connectivity issues with apple carplay... i'm told its gone as high as Hyundai Europe as they are concerned its a software issue. Clearly its an issue they want to resolve.
Remind me what's happening exactly?
@@MrEV When I plug my iphone in it regularly drops out, loses connection. Tried different iphones and cables etc. Hyundai are hoping to fix it in the next update...
Wife’s car 12v dead this morning- what a pain.
What car do you have? Do you have a battery starter?
Might be a good idea to hide your number plate (7:10), did you see what happened to Jonathan Porterfield?
I did! Crazy. That ship has sailed though I think - I've shown my number plate so many times now!
@@MrEV you might be safer as his car also has a ICE version to confuse the matter whereas nothing else looks like your lovely car.
Is this issue of 12v battery solved in 2024? This is a deal breaker for me
I’m hearing fewer reports of it. I imagine the brand new IONIQ 5 coming soon (2025 model year) will be better but I have no definitive info on its 12v management yet.
you are lucky you didt have to call a tow operator
Why have you got your keys in your pocket all the time when at home?
In winter it’s because we have the keys in the jacket pockets. In summer I just keep the IONIQ 5 key loose in my pocket.
Leaving the key indoors would obviously help!

Thank you!
Has anyone checked with Hyundai that fitting an after market BM2 will not affect their car's warranty? Sometimes manufacturers look for excuses not to make repairs at their expense!
I’ve not checked but I’d be very surprised if it did as it’s so easy to remove. My dealer certainly didn’t mention it when I took it in!
It only occurred to me because a few years back I was going to have rear parking sensors fitted to my Nissan and the dealer advised against it as it may affect my manufacturer's warranty. Presumably they'd have to show that the after market part caused a problem but ......
You let your car drain to low,all thay do is change the software so it will charge at a lower %,
Annoying you can’t do OTA update for it.
True, although I'm not sure I'd trust Hyundai's software enough to change such a major part of the car over the air!
So, i´ve never had any Problems, with the 12 V Battery....My car have now over 20000 Kilometers...
I see Tesla have gone to a lithium 12V battery. It would be so much better if they were 48V instead.
Tesla (EM) explained quite clearly that they could do it, but the external suppliers simply don't make the components, which would be too expensive in the quantities needed.
If Tesla hits the critical production number to make that run viable, they will change.
I'm not particularly worried, due to fact the cars are way too expensive, for a mere mortal like myself, to be able to afford one
Nice looking car though
So, moral of the story, if you want a BEV that requires no fiddling, buy a Tesla.
Are they going to refund you for all the pain and minor expense it cost you 🤔
