From all owners who have posted their experience so far, perhaps a dozen, it seems that once you're past the break-in stage, perhaps 7,000 miles (or 10,000 km) the wear particles have already been ground down to a relatively-benign size, thanks to the unwitting actions of the bearings and gears. Ideally the magnetic plug would be installed from new and you'd avoid all that unnecessary wear and added risk of future problems.

But running clean oil is never a bad thing and so the bottom line is to do the work as soon as it's convenient.

Not sure how the service manager would react when I hand him a magnetic plug next week and ask him to change my gear oil at under a 1000 miles. Oh well, if someone would send me the link to the magnetic plug, I will order and report how that caper turns out!!

Look forward to a picture of the original oil.
So far every one (with a few thousand km or more) look like some kind of dark metallic soup.
Perhaps yours may more resemble the "chunky" style:rolleyes:
 
Anyone know how to get these lights off. I bumped into a curb over the weekend and the lights have been on since...EV dash.webp
 
ok so today finally did gear box oil change...

started out late in the afternoon the night caught up with me and so did the cold today was supposed to be warm 36F as long as sun lasted in the sky....

so started out taking the splash panels apart, looking at gear box I thought to my self probably just need the rear one out ... " Wrong " you just need the front one wasted a lot time doing this "specially putting it back together after wards " pretty simple 4 bolts front part and 3 in the rear and 8 plastic push bolts around outer rim holding in place. ( you can see gearbox drain plugs if you take out driver side tire ) black bolts with blue markings.

the 2 bolts in gear box had giant flat head nuts/screws I had to use 1' socket with rachet to get them out my replacement magnetic bolt nut/screw should be much simpler to get in/out as there more area to grab on. 20220125_181858.webp Screenshot_20220126-002420_Photos.webp

as far the oil it came out black in color and bit cloudy as I empty the collected oil back to bottle for recycling no metal fragments that I could see.


100,066 Miles by the way took car for spin I have to say looks like it got bit quieter. but will do real test tomorrow

The oil is missing the blackness that I expected but you can see lots of fine particles when it's poured out.
I have to wonder if it had already been changed at a dealer service because it seems cleaner than it should be for 100,000 miles.

it's only been to dealer for steering wheel noise forget what the part they change around 18,000 miles and cabin filter , tire rotation normally do it my self but was generous toward dealer that day had them do it.... then it hasn't seen a dealer since then. hopefully it continues that way... the most miles I put on a car from 0/new

Well, our EV power train warranty (incl reduction gearbox) in Canada is 8 years, 160K kms. I doubt I will keep the car that long (took 2.5 years to get to 40K kms), so not anticipating any high cost repairs. But I don't expect resale value to be very good in a few years time. So might just end up handing it down to someone in the family. That's what I have done to several past cars, after a fairly long life-time. My son got two of them, and his kids will be car driving age before too long.

I agree. Our 2021 has 21,000km on the ODO and I am not sure how big an issue this really is. Not saying that some folks had no problems, bad stuff happens - but is it pandemic? :( So as a matter of interest I asked my dealer for a quote for a reduction gear oil change and a genuine Hyundai "Plug Magnet". This is what I received:
"Your vehicle takes 1.0-1.1 litres of SAE70W gear oil and the recommended interval is to inspect every 112,000kms We do charge $55/per litre and $39.95 to replace. As for the Magnetic drain plug, after looking into it for you, Hyundai does not supply them so unfortunately I am unable to get one on order for you." The part regarding the magnetic plug seems really strange. I sent to them the image of the plug in its original plastic pouch. I suppose they are not interested to order one.

But back to the need to change the reduction gear oil, I remain skeptical, though the magnetic plug makes sense. I still have 7 years and 139,000km before the warranty runs out.

My dealer ordered the plug (00810-17121) at a cost of $4.56 however upon we checking it at the counter found it not to be "magnetic". I had it installed anyway. I was out the door in 30 minutes, so it is a "quick" maintenance procedure.
The cost for the gear oil (00232-19063) was $53.85/litre, however because there was a need for slightly more than one, I was charged for 2 (not a big deal in my opinion).
Your quoted cost of labor ($39.95) is pretty good as I paid $67.50.
The oil was black from my 21 model ~10K kms, runs quieter now than before, so well worth it in my opinion.;)

You certainly have every right to ignore any advice on this forum without having to justify that to anyone.
My mechanical warranty ran out last October and that's when I discovered the omission of a magnet. Fortunately I have the engineering background to understand both the implications and risk v.s. benefit. The quieter driving experience was just icing on the cake!

I was able to find a magnetic one in my odds and bits bin in the garage so had that fitted, at only 13,000 km the oil is black as black and smells as well.
car now seems to run quieter as well, and i will keep my eye on power usage as well to see if it saves any power as well

I have to wonder what's going on with that part number, the third report of that now. It also happens that Kona (ICE) AWD owners are finding a similar black oil situation in the rear diff at early kms.
 
with the plug, its bored out for the magnet to be fitted into it, and then not fitted for some reason. supply problem possible and no body at Hyundai checked they are getting what they orded from there supplier, the black may be something they use to protect the gear box during shipping and is possible supposed to be changed out on the PDI before delivery as used to happen in days of old. I have been for a 100km drive this morning in 35 c heat and the box sounds quieter and is smother as well , more thought's on the black stuff, perhaps its used in all the diff,s as a assemble lub.
 
Well, as Gomer Pyle used to say "surprise, surprise, surprise!"

An Ioniq owner over at Ioniqforum.com posted photos of the insides of the gearbox after having to rebuild it due to a bearing failure. And, as clear as daylight there's a damn magnet installed! Checking the Russian teardown video of the Kona, it appears that there is one there as well, although completely covered in metallic debris. That also explains why the debris parked itself at the small web that now clearly is there to hold the magnet in place.

Since many of us have seen metallic debris in the oil, I can only wonder if the magnet becomes fully saturated and can't take any more metal?

Perhaps tomorrow I'll find an old magnetic compass and run it over the area to see if I can detect its presence through the casing.

Well, what an interesting journey this has turned out to be!

So if there has been a magnet there all along collecting the "run-in" debris, why, given that we ascribed the oil discolouration to ground up metal not trapped by a magnet or other filter, is the oil so discoloured so soon? (As it was in mine at 3500km).

I trust that with three magnets installed now my gear box oil will last indefinitely:rolleyes: :D
