Kia EV6 12-Volt Battery System Problem Now Fixed!

[@bbatheymca]

We developed the same problem at one year/30,000 miles and went for the $450 lithium 12 V battery. Have not had a reoccurrence of the problem and we’re now at about 50,000 miles. The only other thing we have had to do is replace the tires so this car has been, very cheap to operate and we love it. 3:35

Thanks Blade! the Kia is a nice car - but all it takes is one bad thing. The jump pack and utility mode ar work arounds - but doing that everyday is going to be a ral pain.

[@batteryblade]

Your welcome here is the link to the jump pack I used! 😉NEXPOW Car Jump Starter, 2000A Peak 12V Portable Car Battery Starter, Auto Battery Booster, Lithium Jump Box with LED Light/USB Quick Charge 3.0 a.co/d/8tKazem

[@allannielsen1546]

I have never had any issues with the 12V battery - not even once. Have had the car for two years - EV6 GT-Line.

[@jimbrown341]

@@allannielsen1546 Do you live in a cold climate (during winter)? That might be the issue. If you live in a warm climate you might not experience these issues as easily. Cold winters do damage on batteries. But I will say that car batteries do die. I owned a Kia gasoline engine that I bought used with about 33k miles on it. I would say somewhere around the 50k mile range the battery died in the middle of Winter. Luckily, I had AAA service. Probably everyone should have it. AAA came to my location within 45 minutes and told me they could replace the battery on the spot. Took no longer than 1hr 30 minutes from the time the battery was dead to the time they arrived and replaced the battery. The cost to replace the battery was $160 back in 2020 from AAA's service. So yeah, car batteries die and need to be replaced eventually. No warning for when it happened to my Kia gasoline engine.

[@allannielsen1546]

​​@@jimbrown341I live in Scandinavia... As a precaution, I have just replaced the 12V battery with a more powerful one.

[@batteryblade]

Yes I live in cold state of Michigan!

[@Vegetarianlifeforme]

I'm so glad there is a solution

[@batteryblade]

Not a good solution, the only thing that worked for me was to replace the 12-volt battery!

[@mitchellbarnow1709]

Great video Blade! I’m really surprised that KIA has not come up with a software update to fix this. My 2018 Tesla Model 3 always monitors its own 12 volt lead acid battery. I know because I put a battery monitor on it that records the battery voltage every so often.

[@batteryblade]

Me too it seems the kia only charges the battery while on a generally too long of a timer and if your battery is going bad in the winter your out of luck!

[@lanternhillmorgans3330]

Thank you very much for this timely video. I bought a used 2022 EV6 three months ago with 16K miles, just over 20k miles currently, and got stranded at the transfer station 2 weeks ago. Got a jump from a local garage and the car was dead a day later. Same driver towed it to the dealership and the 12volt battery was quickly replaced under warranty. Two days ago the amber dashboard light came on showing the car is charging the BRAND NEW battery!! I will be parking my car in Utility mode and turning off the app notifications. And contacting Kia to voice my opinion...😟 This is an unacceptable situation.

[@batteryblade]

So so sorry to hear that, the 12-volt system should be recalled altogether as it's such a bad and common problem with the owners. I will never buy kia or hyundai again! They are ruining their reputation with the way they are handling the situation, the ev6 could have been such a good car to recommend!

[@phuongdh]

You're lucky they replaced the battery. My battery needs to be jumped every single day yet they refuse to replace it. They say it's still passing some stupid test.

[@lanternhillmorgans3330]

​@@phuongdhI know I'm lucky and have learned there are ways to work around further issues such as not using the app to check on the car regularly. I also unplug the cellphone charger whenever I park the car. I do have to wonder why you put up with jumping the car every day...if the dealership hadn't replaced the battery my next step was to replace it myself.

[@lanternhillmorgans3330]

​@@batteryblade It is definitely an issue as I have learned from other sources, too. It might be partly the way the 12 volt battery is constructed and the way it works in an EV rather than an ICE. If it happens again I'll look into a different type of battery. Thanks for your reply and your helpful video!

[@MrsPsclass]

Pretty surprised there could be this kind of problem with Kia.

This is utterly stupid. Stupid, stupid, stupid. For gods sake Kia, putting 3 engineers on this for a few weeks would forever have solved the problem. This is NOT rocket science.

[@orangezebra8668]

Learn more about this it isn’t a big deal

[@MartinHultquist]

Thanks. My 12v died the other day. I still have to struggle with the dealership since they don't want to replace on warranty. I love my car. Best car I have ever had. But I must admit, struggling with battery replacement was not what I expected when buying it 1.3 years ago.

[@AVTProjects]

why have you not went to KIA to get a NEW 12V replacement under warranty to start with? That would take some headache away atleast.

[@KENZIIE_lol]

The problem has been confirmed to be a faulty ICCU (Integrated Charging Control Unit) in certain EV6's. There is a recall in effect for this problem. Only some EV6's are affected. The dealership will replace the ICCU or the ICCU fuse free of charge (no pun intended).

[@batteryblade]

Great information to have!!

[@gianfrynco]

confermo che c'è il richiamo ed io l'ho fatto sulla mia EV6 GT

[@encldesign]

May I know the problem will be completely solved after replace the battery? even ICCU problem? thanks!

[@V-eg6ds]

Thank you for the video. Is the Kia ev6 still running well with the new 12volt batter? We are having issues with the alerts and drained 12 volt too.

[@batteryblade]

Yeah the kia hasn't had a problem since replacing the battery!

[@J-Post86]

Same issue with our 2024 kia niro. 2 batteries replaced under warranty, car has 5000 miles on it... Definitely getting the lithium battery this time.

[@batteryblade]

Sorry to hear that, I just don't know why Kia would put such bad batteries in their cars while having the worst 12v bms system in the industry. They are setting up the owners for a bad time!

[@Joanbaumgartner]

please show up close where you connect the cables to the 12 volt battery. Could not see due to your camera angle. Thanks

[@nathanlinares5503]

Seeing that getting an AGM battery helps a lot

[@jadedtrash]

Did you find this issue again after changing battery? What is the brand/size of the Lithium battery you replaced it with? I just got a recall notice for something having to do with 12V battery but not sure this will fix it.

[@batteryblade]

Replacing the battery has completely fixed the issue I will let you know the information about which type I chose when I get time to check

[@jadedtrash]

Thanks!

[@DanielBrownOre]

After my brand new '22 Mazda had electrical probs after only 2-3 weeks from new, I bought an LFP battery and didn't look back. Now have traded it in for an EV6, I just ordered another LFP battery for it, knowing that most manufacturers are choosing to use cheap 12v batteries as part of cost savings. Not sure why the video poster just didn't get another battery for $150 or less instead of $260 from the dealer.

[@batteryblade]

I didn't get a new battery from the dealer I installed it myself I should have made that more clear but honestly missed big time by not filming that and including it as part of the video!

[@DanielBrownOre]

@@batteryblade Ah, no worries, it's not like those cheaper ones are on the shelf at physical stores when you really need one either! :)

[@81bestof]

great video man. But it is a shame that this is a problem in the first place : /

[@SantanKGhey1234]

Why don't you change the battery?

[@paulpacey2936]

Great car, but rubbish battery. Unfortunately here in England we also have an abysmal Kia dealership network; you can't get an answer on the phone, you drive to the dealers, as I did yesterday and the soonest they can look at my car is four weeks. One dealer said the battery is only warranted for a year, another said two years, they really don't know what they're doing, and don't appear to care. I won't buy another Kia.

[@batteryblade]

I felt the same way that it ruined my trust in kia that they could handle a simple issue so poorly! I replaced the battery out of pocket and it seems to be fine now.

[@joemejoe909]

What year is your car?

[@batteryblade]

2022

[@lenmason259]

Had my EV6 from new for around a year and 20k miles with no issues at all even had the ICCU recall upgrade done and about 1 month later the 12v battery died triggered by having the tailgate open for about 30mins. I already had a Noco boost box and was able to get started again but a few days later it died again. Called my kia dealer they were great looked at the car same day tested the battery it failed the test and they replaced it under warranty right away. A few learnings the factory batteries are just poor quality or not suitable for EV usage patterns, the ICCU recall does not appear to fix the issue, its well worth buying a boost box and keeping it in the frunk just in case and in UK the dealer franchise model means you can get a good one or a bad one. Mine is wessex kia in Newport wales. I do expect the replacement is not likely to last more than a year but would definitely consider replacing with better quality option if not covered by warranty, otherwise EV6 has been fantastic and wouldn't swap it for anything else.

[@jlennonfan2424]

got a 2024 5 months and its now had 2 batteries in 3 days doing this same thing Kia is blaming the EVgo and EA apps

[@batteryblade]

@@jlennonfan2424 that is just crazy I have lost all respect for Kia for making a great car with such a Achilles heel and denying responsibility for it!

[@LatinRemix]

This had been fixing my car, until today. The jumper did not start my car.

[@BlackYellow07]

How much to replace the battery,$20k or $30k?

[@batteryblade]

The 12-voltage battery total cost to replace was $260. The high voltage battery isn't the problem or a common issue

[@AMan-he9sz]

Kia equips their cars with 2 year batteries, and they always have - It's not a great battery and won't last long. Do you have all your updates? My Kia EV6 has the same lackluster battery - but it does condition the 12 volt battery when it needs to, and the battery doesn't die. When the yellow light on the dash is lit, I know this is what is happening. I leave notifications on, and my battery is good.

[@batteryblade]

Yeah your kia's battery is still good enough to last in between when the car charges it, but once the voltage gets too low the cars bms almost gives up on charging it its extremely strange! Some of the bms software issues admittedly may be fixable if I took it to a dealership, but that seems silly when the car is capable of ota software updates!

[@AMan-he9sz]

Earlier examples of the EV6 can experience the issues you describe - and may not be fixable by OTA update. IMO, it is a worthwhile endeavor to take the car to a KIA dealer to have this fixed. Sorry you've had to experience this - but I do believe it is entirely fixable, battery replacement notwithstanding. @@batteryblade

[@alexgasess5834]

Are you going to replace 12v battery every 2 years? ‘Do not replace the battery via dealership’ is a wrong advice as you encourage the irresponsible behaviour from KIA and KIA dealership. They have to recall EV6s. This is not your problem but theirs!

[@grantrandall1674]

Get a decent battery tester (Topdon?) and check the capacity %. Prove to kia it needs replacing!

[@markfp9705]

Are you telling me the way to fix battery drain on a 65k pound new car is to buy a battery start pack?! Jesus

[@johnporter5828]

Will consider a KIA whenever or if they have a permanent fix.....

[@eugeneputin1858]

Literally dumbfounded why you decided on a kia when you already owned a tesla. Brand new ev with legacy tech.

[@batteryblade]

Bought the Kia Ev6 first then the Tesla, but you definitely described the ev6 pretty well, although the charging and battery tech inside it was pretty cutting edge when it came out!

[@eugeneputin1858]

@@batteryblade Ohhhh gotcha. Ye makes more sense. Great 800v archi but only when it works v true

[@andybrown3715]

Replace with an LFP 12V and the problem goes away.

[@virum1]

Bad batch of batteries.. check the recall...

[@batteryblade]

The only recall I see on my kia connect app is the roll away risk recall which I haven't bothered fixing yet! 🤔

[@orangezebra8668]

It’s really not a big deal Possibly left a light or fan something on or an upgrade turned something on The 12 volt battery operates the dash, fan, lights etc If you don’t drive the ev6 for 10 days or so the 12 volt battery can go flat

[@batteryblade]

Before I replaced the battery it would go dead within ten minutes of turning off the car which certainly is not normal!

[@gianfrynco]

@@batteryblade devi fare il richiamo ICCU presso il concessionario

[@MikeCarter]

@@batterybladeyeah same for me. Having the boot open to load or unload stuff would be enough to kill the vehicle 12g battery and leave me stranded !
