In this video, I show you how to change the reduction gear oil in a 2017 Hyundai Ioniq Electric 28kWh electric vehicle. Our Ioniq has now done 87,200 miles and this was its first gearbox oil change. The oil to use is 70W API GL-4 manual gear oil.

The Ioniq gear reducer is the same design as used in the Kona and Niro. Some of us Kona EV owners have recently been changing our oil as early as 4,000 km on an urgent basis because (EDITED) in every case reported the oil comes out black. (EDIT2) But after 3 changes my Kona is no longer doing that.
The other issue I have to mention is that you've used the wrong oil. The specified grade by Hyundai is a 70W or 70W-75 GL-4, such as their own DCT gear oil or Redline MT-LV. A 75W-90 has nearly three times the viscosity and is not ideal when you have a pinion gear running at perhaps 8,000 RPM. A 75W-90 weight is not the "highest grade" of GL-4, it's just thicker and a multi-grade. I'll also point out that the specified capacity is 1.0 to 1.1 litres. Thanks for your video though, we have to get owners to do this maintenance much earlier than the 120,000 kms in the "severe use" category specified by Hyundai.
According to the service manual for the Kia Soul EV, the drain plug gasket should also be changed when changing the gear oil, but I'll be damned if I can find someone who sells the darn thing. Do you think this is really necessary? Or, do you know where would be a good place to order one? I've tried Kia parts specialists online and they don't even list the thing, or maybe I'm looking in the wrong places. Is it a rubber or cork gasket or is it metal?
@@JustWasted3HoursHere No need to change the gasket but Amazon has them if you search for the drain plug, DP007
@@paulaxford6754 Thank you. I found several drain + gasket (crush type) matching DP007 (including one that is magnetic, which is great) but Amazon's fitment feature says it does not fit my Kia Soul EV. However, I imagine it's because the EV does not have an oil pan (which is what this drain plug is primarily used for I guess). Do you happen to know the size of the plug? This one is an M14 x 1.5.
@@paulaxford6754 Or, do you have a link to that Amazon product? I get a ton of results when I search for 'DP007 drain plug'.

Nice work. This is becoming a forgotten service as people are used to hearing EVs require no maintenance, but definitely needs to be changed!
Well, the manufacturer's will so not, but probably wise too as it is only one litre of oil in most EVs.
@@GoGreenAutos Very true. "Fill for life", a much shorter life, they don't tell us that part. Since it's gear oil, likely best to treat it like a differential with its service intervals. Someone locally with a Kona changed theirs much earlier than yours and found the oil was dark with minor metal wear, makes the case for doing the first change sooner than usual due to the initial gear break in when new.
thanks for this tuto, I have saved it for later, please make more tuto for ioniq maintenance at home
Thank you, really useful how to. As I own hyundai ioniq electric, I would also love to have a video about flushing the coolant. I haven't been able to find one yet.
That's a job I've not done yet.
Great video! thank you. I'm going to do this ahead of schedule on our Kona EV. I've been reading the fluid is high and iron and jet black by 10k. thanks again
It is also possible to add the new oil from the top if you have a funnel with a long tube attached to the bottom. An assistant here would be helpful. This method may even be preferable because many of those hand pumps use lithium or other grease to lubricate the plunger inside and some of that could potentially make its way into the gearbox.
To fill oil in a boat gear box, i use a hand pump, its the same problem ,its up hill. The make i use is “quicksilver”.
Nice work, would be great to do one on a leaf at some point in the future
Yes that will be coming. One for the ENV200 is already filmed and stacked up to go live in a few weeks time and its an identical process on the Leaf. A Leaf video will also be done when I next do an oil change on one.
Omg wonderful information! Thank you so much for providing this info . Out car have now around 95000 km and I don’t think this has been done by Hyundai last year when they did the last service.
I could ask…
No, Hyundai wouldn't have done this as its not part of any scheduled service.
I'm no mechanic, but I've read in a thread that it has no filtering, and no magnet to stop metal grindings going around in the gearbox... So these gearboxes have a tendency to explode in the Ioniq and Kona of those years. It's recommended to switch out the drain plug with a magnetic one, so it attracts the metal filings. Seems reasonable to me. M18 x 1,5mm is what I've just ordered, as pr. The thread. I will correct this if it doesn't fit.
Great! Let us know if it fits and how it works. I'm inclined to change the oil twice. First, just to flush it and be able to install the magnetic plug. Then I'll give it a quick highway ride, draining the oil afterwards to check what got collected on the magnet before filling the final fresh oil.
Any update on this drain plug? I’ve used them in previous ICE cars and looking to get one for my Ioniq
@@tommoger Well, it fits. If it does anything that the box doesnt do itself, I don't know.
@@MartinPedersenTM great thanks!
@@32bits-of-a-bus59 The oil was black as cola... but didn't smell burned. I don't know. Car drives fine...
Very interesting little video. Thank you!
Glad you enjoyed it!
i saw that the drain pluge isnt magnetic. someone replaced it with a magnetic plug , but he did say there was quite a bit of metal in there
A few of us Kona owners are now using magnetic drain plugs, same gearbox design. It will allow normal change intervals without having the oil turn black.
Nice vid. What was the state of the old oil?
I guess this oil change is important as the input gear from the motor can spin very fast >10,000 rpm? and 'batter' the oil.
'Sealed for life' statement from manufacturers seems a bit dodgy..?
Old oil in this example was actually fine. I've seen Nissan Leaf and ENV200 where its not. A video on that is coming.
@@GoGreenAutos Sealed for life does mean nothing. Since the lifetime is not defined anywhere, life may just be shorter than if the oil is changed.
Had that problem with my BMW with the ZE automatic gearbox that was "sealed for life" .... life was just 180000 km.
Well, first Thank you for this video. I would have relied on the Hyundai Service to do this, but since officially the gearbox is lubricated for lifetime, they might have never done this.
My Ioniq has 81000km on the clock now, means it's about time to change the oil and put in a drainplug with a magnet. I wonder how the old one looks like.

Is the synthetic (the red one) better than the one u used?
Nice I am wanting to do the same on my MG5 (currently 42.5k miles and rising by 800+ a week) soon. Where are you based? Perhaps we can get a video out on that one too if you are interested?
Based near Wantage, Oxfordshire. Any good?
@@GoGreenAutos yes can stop by when going to relatives in Farnborough in 2 weeks time.
@@williamarmstrong7199 Do you know what spec oil it uses? The MG5 (or ZS EV) is not on the Castrol oil finder yet.
Informative as ever do you or have you ever exported a vehicle to Ireland . I'm interested in 28 kwh ioniq premium se ( not a fan of seats in premium spec)
Sorry, no. Too much additional work with the VAT and deliver so don't do with exports.
@@GoGreenAutos is that because of Brexit ?
@@rodden1953 No, was the same before. Not even tried since.
Thank you for the informative video. Can you film a Renault Zoe reduction gear oil change when you do one?
Yes I will do one.
Love your work! I own a 2017 Ioniq with 120kkm on the odometer. It has developed a slack in the drivetrain which is very noticeable when the motor goes from powering the wheels to regenerative braking or any stop and go traffic. It is unfortunately out of warranty, and Hyundai wants 4000€ for the replacement of the whole motor, reduction gearbox and differential unit...
If you were to make an educated guess, where do you think the slack could originate? And would it perhaps be possible to perform a repair instead of replacing the whole unit?
I already checked the constant velocity drive axles for slack, they are fine.
That seems cheap as in the UK a reduction gearbox is about £4,600 and the motor is about £6,5000 ! Ridiculous prices I know, but that is what the parts list as.
If you've already checked the joints on the drive shafts, then I would say your slack must be in the reduction gearbox. It takes the drive from the motor and gears it down to the differential at the bottom.
Thanks. Changed mine diy
Glad the video helped.
thanks for this vidéo
Hello... Does anyone know What is the recommended oil that has fullfil these spec : 70W- APi GL 4 ?
Very informative.
Do you know if it is a service item on the MG ZS?
I assume every 5 years?
I've can't remember on the ZS. Even though I did own one of these myself, because it was so new, I never looked. Many manufacturers don't have the reduction gear oil as part of the normal schedule as they say its "sealed for life".
@@GoGreenAutos well, mine isn't sealed anymore thanks to driving in 40 degree heat in the desert. While I still have the warranty, I still think I should at least ask them to check the level.
@@dgurevich1 The level can't really drop unless there's a leak.
@@GoGreenAutos yeah, I saw some of the gear oil seep out of the top vent plug but only in very hot days.
Maybe it's OK to leave it as is.
May I ask you which torque (Nm) level is need to fix the m18 Dragon plug?!? Could you write the official Hyundai Range? What type of Deák USE In the Oláh ? Metal?!?
35-40Nm. Also see the follow up video czcams.com/video/QhJOI4lYF1c/video.htmlsi=VuufEx9_lzSlQLJE
Thank you for an amazing video. Is it possible to also change the oil filter? As far as I know, Tesla has one, so I suppose Ioniq might have it too.
It does not have an oil filter.
@@GoGreenAutos That's interesting! Hopefully it at least has a magnet somewhere inside to keep steel micro particles that were ground-off the gear wheels during the first months of operation away from the gear surfaces. Otherwise it would make a sense to change the oil much sooner to prevent abrasion from these particles.
@@32bits-of-a-bus59 The Ioniq doesn't seem to have a magnet. Nissan's do - that video is coming soon.
@@GoGreenAutos Thank you for valuable information. So, unless the magnet is buried deep inside the gear box, the early oil change is even more important than I originally thought.
@@paulaxford6754 Thank you for the tip on the magnetic plug. I'm still quite shocked that they left out any measures to keep the oil clean from the design. Otherwise , Ioniq is such a good car for its price.
So just replaced mine but it seems you have changed the oil you specify in the video! Hoping the 75W90 is going to be ok?
It will be fine. The inside of these gearbox are very simple.
Hi
Nice video!
My car has now around 8500km and it wants a service to be done.
I am now wondering if I should give it to Hyundai or do it myself?
I don’t really know what should be done att this mileage?
Any recommendations for me?
I’m a bit concerned that I just waste money if they don’t do anything extraordinary that is very hard for us deadly people “ to do ourselves 😅. For example… if they check the electrical system etc. At this moment I have actually left it to Hyundai just cause I get a warning triangle that the cars electric system has some kind of failure (with warranty) even though it drives perfectly fine.
That and the right side headlight has gone bad so I have to have some instructions of how to change it (maybe manual).
I appreciate all the help I can get🙏🏻.
Thanks ahead!
Best regards from Sweden

I would do it yourself if you're capable. Hyundai dealers don't consider this to be part of a service and would probably say its not required. They would have to buy in the oil. I've seen so many examples where cabin filters are not changed by main dealers, yet invoiced for on a service receipt. The same for brake fluid too. I would not trust that they would actually do it.
Just out of curiosity, do you feel any difference in the drive after this job?
No, not at all. Just for peace of mind and longevity.
@@GoGreenAutos ah right, that's perfectly reasonable.
@@mrmuds8624 you would think not because there is no obvious science behind that but anecdotally some of us Kona owners have noticed the car runs smoother after getting that black oil out.
That’s really interesting. Should reduction gear oil be changed on a distance driven basis or on time? We’ve owned a Kia e-Niro here in France since March 2019, so one of the oldest around, though we only do about 20,000 km a year in it. What would you recommend?
Some manufacturers say the gearbox is sealed for life and do not have an oil change in the service schedule. But best to change at around 60-80,000 miles or so. I generally do Nissan Leaf & ENV200s at about 30,000 miles as I've seen more wear on their reduction gears. If not specified by the manufacturer, no fixed rule on this. But as always, best to change early and have no wear.
@@GoGreenAutos Thanks, much appreciated. I will see how things go over the next few years but at 100,000 km I may book a reduction gear oil change with you when we are visiting the UK.
@@GoGreenAutos I was wondering about that. I have a 2016 Kia Soul EV+ and it doesn't list gear oil maintenance at all in the service schedule (if I remember correctly). Since it is supposedly "good for life" and sealed in, do you think this could cause a warranty issue later on?
@@GoGreenAutos you said 60k miles so does that mean 100k kms ?
@@clayton4115 Yes, but there's no set figure here, unless your vehicle's service schedule specifies one.
Roughly how much room/height off the ground would you really need to complete the work?
I've done my Kona 3 times now and the simplest and fastest method is to lift the car at the left side or left-front only, getting the tire about 5cm off the ground. You can squeeze under and remove the cover and pull the plugs. Replace with a measured volume of oil from the top using a funnel and tube (eg, what it says in your owner's manual). The Kona needs 1.05 L and as best as I'm aware has the same gearbox so I'm unsure why the author here needed more.
Looks overdue by the blackness of it even though it probably not even recommended to change. Like tesla. Cheap insurance to change it though. Tesla has a filter for their fluid in the 3 and Y I think. A spin on filter like engine oil.
Yes Tesla do have an oil filter. But I also think the oil in a Tesla oils the motor. The Hyundai oil is just the reduction gearbox, so no filter.
The "blackness" is entirely due to the missing magnet allowing ferrous wear particles to circulate and be ground down to a fine dust by precision bearings and gears. By no stretch of the imagination is this acceptable in any modern design.
How often should you do this service?
I'd suggest about every 60k miles or so.
can a normal car mechanic do this job or is it a job for the hyundai dealer?
Anyone can do it. The point of the video was to show that many owners can do it with the right tools.
@@GoGreenAutos thanks, great video too !
Imagine owning an EV and having to an oil change every 87,000 miles how awful
and it takes 1.4 litres!
@@GoGreenAutos How are the stealerships making any profit at all on the service of EVs ? I don't feel bad 🤣
Thank you for sharing..
I have some technical issues with my Hyundai Ionic, would you please leave your email in the comments so I could just send you my questions?
As bad as outboard motors for boats! Why are these oil systems designed uphill and against the flow! Harder to avoid spillage.
Still needs oil I see, that's quite ironic!
But it is fully synthetic, so does that count?
@@GoGreenAutos who knows? Depends which CZcams video you choose to believe!
@@GoGreenAutos I don't really go for this green trend we are in, can't afford to be green and I'm sick of having to compromise my life because of the problems caused by wealthy folk, I'll continue driving old cars until I hang up my driving gloves!
