Thanks for sharing this great video! I think this will be super helpful for new Hyundai service EV techs to see how this is done RIGHT! I am waiting (like many others) for my drive battery to be replaced on my 2019 Kona EV. I assuming this is a Canadian Hyundai dealership? I do see on the left side the Kona EV heat exchanger box which was not available U.S. buyers. Now I can appreciate how this will cost Hyundai recall 200. I was told Hyundai is billed $11,000 for parts and labor for recall 200..

[@garyboyce6186]

I was curious how much the Kona battery weighs, it looks really heavy. It drives like a heavy tank in the snow and goes anywhere. Regenerative breaking is safe in the snow as well. . Amazing. I really like my Kona EV and am also waiting for a new battery. Apparently I’m number 3 on the list now. Thanks for taking the time to make this great video !!

[@hyundaitech]

I think if im not mistaken around 500 something kilo.

[@paulaxford6754]

Thanks for the video. I'm waiting for my Kona EV battery to be replaced in the next few months.

[@Blue-moon12]

How old is your Kona? Why are you replacing the battery so soon? Thanks

[@inf0mike]

@@Blue-moon12 Thousands of Kona Electric batteries are being replaced under a worldwide recall program due to manufacturing faults that can cause safety issues. The batteries are not manufactured by Hyundai. This only impacts vehicles between 2018-2020.

Nice to see that the cooling system is self bleeding with the scan tool activated coolant pump. The bleeding procedure on the Bolt EV is a bit more involved.

[@hyundaitech]

Really? Are you tech too? Thanks

[@blownb310]

@@hyundaitech yes, and you need a special tool that puts the cooling system under a vacuum to refill a Bolt EV properly.

[@stephenclay6852]

Interesting video. The obvious question is having heard so many wild prices quoted by different people is how much to change the battery complete with labour costs.

[@DBartel2000]

Tnx for sharing tis very interesting video.👌 I have a Kia e-Niro MY22, but believe most of the work is the same...

[@hyundaitech]

Im not familiar with Kia but since they are just sister company i believe most of the components are the same. Thank you

[@actii]

I am asking for the impressions of those who are after replacing the battery and possibly updating the software. Something has changed ? Maybe the service technicians from Hyundai told you something interesting about the new battery ... Are these the same batteries as installed in brand new cars from 2022? Does a battery change restart the 8-year warranty? Thank You for Your time

[@slowcatto]

The “new” battery has resulted in a reduced range - feels like about 95 percent charge compared to before. Since Hyundai gave no paperwork or details about what the battery change involved, makes you wonder. Not saying that it would be easier and cheaper to just recalibrate the software (say, to make 95 percent, or whatever, the new 100 percent), but hey. Also, sitting around in Tilbury for about 6 weeks has caused the 12v battery to suddenly die (that's according to Hyundai Customer Care and an AA recovery technician), which the dealer says is not covered by warranty as it's more than 2 years old. Hyundai Customer Care suggested I could ask the dealer to submit a goodwill request for Hyundai to contribute to the cost of a new 12v battery. WTF? A 12v battery only costs around £90 to replace, but it's the principle… Hyundai and/or the dealer should cough up without me having to beg for this small sum, especially as it's been suggested Hyundai is directly responsible for the battery's demise. Shows where their priorities are, once the sale has been made. Pretty poor attitude.

[@thomashenden71]

Probably they have increased the safety margins in the top and bottom percents of SOC, and if nothing else, it increases the life of the battery which is a nice tradeoff. If people are affected by a 5 percent decrease in available capacity, they ought to have bought an EV with even longer range. Other than that - Hyundai’s 12V system sucks and if they really charge customers having an issue with the 12V battery because the car has its traction battery replaced, that is immoral business practice. Most cars with the same electronics / drivetrain, Older Kias, Ioniq, even Ioniq 5 and Niro have 12V issues. Seems like the engineers originally planned to use a LiFePO4 battery that would have had much more capacity and tolerated discharges much better, however they are more expencive so management probably cut them out. Ioniq hybrids actually have the LiFePO4 battery, AFAIK, and replacing the outdated lead acid battery on the other cars shoujlf be fairly easy, though expencive, still the most cost effective solution in the long run.

[@slowcatto]

@@thomashenden71 In 2018 when we ordered our Kona EV (on about a 9 month wait) it was advertised with a 315 mile range (enough to comfortably get to London and back from where we live in Bath). By the time the car was delivered that range had been modified due to new testing regulations - now 285 miles range. Annoying, but still enough to do our regular journey to London and back if we were careful. After the recall I noticed around a ten to 15 percent drop in range. Now, every journey to London requires around an additional charge of £15 on the way back. That's around £1,000 a year extra for us. The additional time spent charging (which had been unnecessary before) makes each trip a pain. It’s impossible to get a response from Hyundai, about any issues - they just ignore phone calls and emails. Saying we should have just chosen a car with longer range is not really helpful - we chose one with a 315 mile range and now, thanks to Hyundai's sharp practice, have one with a 240 mile range. That’s rubbish…

- and do you know if it will be possible to change a 1 phase OBC to a 3 phase charger?

[@heartobefelt]

Nice clear video , i appreciate your effort.

[@villaresidence1]

Hi. Are there any other things to do after replacing the battery, like changing or updating the software, coding or decoding the battery New and old? Or just replace the baterry and the car is ready to go. Thank you!

[@hyundaitech]

If theres availabke update for the BMS and yes yiu have to do that, during the replacement of the battery, just bleeding the coolant and resetting the battery state of charge.

[@mingliang4159]

This is a wonderful video. Thank you! Hyundai or the local dealers don't have this particular EV battery antifreeze in stock. Is there any coolant or antifreeze suitable for Kona EV?

[@hyundaitech]

Im not sure in the aftermarket side, i think you just have to wait for the oem.

[@ferfrdfsfwf]

Hi. Great video! Quick question for you: when I rotate tires on my Kona Electric, do I need to do anything else besides resetting a maintenance reminder? Thanks!

[@hyundaitech]

Technically no, but its a good practice to just visually check underhood especially the coolant levels and i think thats about it. Hope that helps.

[@user-th9qi3xf4o]

Hello great Video. My Kona EV 2023 had bad pothole collision. It bended the tire rods and wheel alignment. The tech says the EV battery sensor for coolant shows up as an error and may need a battery replacement as well. Do we really need to replace the big battery? There are no dents on the battery and the car is drivable with no airbags activated at the time of collision with the pothole. I suspect the Hyundai dealers are playing games with me. Any suggestions and help is appreciated with options i have.

[@hyundaitech]

Hi, so theres a code for temperature sensor for the battery? Maybe the sensor or the circuit got disturb during the collision. I dont know of they can just disassemble the battery and replace the temperature sensor, or maybe they dont have the special tools to reseal the battery thats why they are suggesting a new battery. I hope car insurance will cover your repair coz thats really a big money.

[@filipprusac7702]

Hi. I recently discovered rodent damage at one of the main electrical cables. As far as I can see there is no problem to patch it up with vulctape. If I pull out the plug under the back seat, will the car work as before when the put back, or do I have to connect to a computer. I'm really happy with my 21 64kwh Kona. Soon to reach 90.000km.

[@hyundaitech]

As long as you are not reolacing components, and you just as you say to patch up, unplugging the safety plug and installing it should be fine

[@Ernesto-te7oj]

Nice video! I bought a spare wheel for my kona ev can i just jack it up normal one wheel at a time. I noticed where you had the lift arms positioned on the kona?

[@hyundaitech]

I believe you can still jack it up 1 at a time, just make sure you jack it up in the right position not on the battery frame.

[@thomasnielsen6770]

Can you make a video how much more the new battery can charge I have a Hyundai Kona that’s also must have a new battery I wonder what kind of batteries that i am getting,

[@hyundaitech]

Hi there, i really dont have information about the new battery on how much more it can take, but in my opinion it should be the same. We just replace the battery because of those specific batteries has internal defects on them. Hope that helps

[@bvqbvq]

What's the rectangular panel on the bottom of the battery? Is that the pyro fuse location?

[@hyundaitech]

Yeah thats where the serviceable fuse located.

[@bvqbvq]

@@hyundaitech thanks. Is it likely to have blown in a crash where none of the air bags have deployed? Is there any other reason why the car wouldn't drive after light front damage? The crash was sufficient to badly crack the bumper and fold the front edge of the hood.

Good video. I am in the UK and have been waiting for over 5 weeks while they took my car for a high voltage battery replacement. Before that, the 12v battery failed, but HUK say it is out of warranty - the car is 3 years old. Do you update the cars software to put back the correct power output and charging levels?

It’s been in the shop at Crenshaw Hyundai in Burlington NC for a month and they still can’t tell me when the battery will come in. They won’t give me a loaner. Their customer service is competing with Hyundai Customer Care to see who can be the worst. They’re tied at the moment. I’m calling the Hyundai corporate office in South Korea tomorrow night and see if they can help me. Now I’ll never be able to trust the car again. I guess it’s a lemon. Maybe Toyota will be better.
