You are right- that would be a good deal "normally", however as @navguy12 mentions, there is a TSB. Here (credit @KiwiME ) you will find the copy.
This is presumably USA so a different # for Canada is involved. You will see the dates apply to Kona EVs equipped with the BSC-1 coolant manufactured from May 7th 2019 thru Oct 12th 2021:)

Thank you! Based in this info I should get this work done for free. I sent all this info to my dealer. I am going to see them after the Canada Day long weekend. See what happens.

That is the best way, go during a slower period (say early afternoon) as they should have time to locate the Cdn applicable TSB on their computer.
 
Here is what my local dealer is recommending for my 60,000 km service. I am hoping that the Invertor Coolant that they are referencing is the low conductivity fluid that is being discussed here.

Total: $509.90
Type 1 SERVICE
HYUNDAI CANADA REQUIRED
Hyundai Canada Service 1
Replace Inverter Coolant $429.95
Inspect Reduction Gear Oil
Tire Rotation or Perform Seasonal Tire Swap On Rims

That price doesn't seem out of line, but it doesn't hurt to confirm. The timeline is right for LC coolant replacement so I would expect it would be inclusive. ;)

I checked a few owner's manual PDFs that I have and all are the same, much earlier than I thought it was.

Once the panel is off and the plug removed it seems silly not to just change it for the sake of the cost of a bottle of oil.

Huh. I've sold my '19 so I don't have my original schedule anymore. My memory was that the interval was something like 100k+. But I could easily be mistaken.
 
I’ve always thought it was 120,000 km but I’ve never looked closely. It might be that I’ve seen 120k as a replacement interval on some schedules. I take inspection to mean check the level only.

I have a $AUD700 coolant service coming up at 60,000 kms.

Hi Just had mine done under recall free, you need to check if yours is the same Blue fluid, replaced with more Blue fluid, it takes 2 days for this to be done,
dealer gave me a IO6 to drive, just need the extra $35,000 to pay for it.

Mines a '22. I don't think it's covered by the recall.

I had my blue coolant replaced under RECALL around 40,000km. Hence I should be OK for a while - 100,000km? The work did not take two days. But after a got my car back there was a 1/2 jug of coolant in the car with instructions to check coolant level and "top it up" as needed. By the time I got home from the dealer (~10km) the coolant level was well below Min. A topped it up repeatedly until the coolant jug was empty. The dealer gave me an other jug. 1/2 of it it still in my garage. Apparently it takes a while for the coolant to cover the whole system. Maybe that is were the two days come from. But unless the car is driven the coolant will not be circulated and settle. Supposedly there is a special vacuum pump to clear the old fluid out of the system. Maybe my dealer did not have it.

According to my service manual the reduction gear oil supposed to be OK till 120,000km. Inspected at 60,000km intervals. There is a loot of discussion on this forum how often this oil supposed to be changed. I am not going to take sides.
I was quoted C$334 for oil+labour tax in. Using 2 cans of Hyundai MTF&DCTF SAE 70W synthetic oil @C$79.95 each +tax. Even if one is not a DYI person, I am quite sure one can find a more economical solution for that work using your favourite mechanic.
 
Just wanted to share my experience. Have a 22 Kona EV. Had read all about the green/blue issue. Local dealer in Erie PA said it would be 300 for a change. I inquired whether that was correct, and asked them to confirm that it was the blue fluid, which I have. They "checked into it" and then told me it would be 400. Bad, I know. I called Shults in NY, where we bought the car, and they quoted 140. That's not a typo. I spent an extra hour on the road, but got the change done for 140 US $. Very happy. The new fluid is . . . blue. At that price I don't care about conductivity and I have no interest in DIY, which I would normally do. Not worth jerking around with a critical component.
FYI, interval change specified in the manual is 30k. We were well over that (45k), but I wasn't concerned, given that 1. the crystallization issue was pre- my car, and 2. the fluid doesn't lose it's cooling capacity within that time frame.
The Erie dealer is ALWAYS very expensive. They wanted something like 800 dollars for rear disc brake pads, and told me I should get the front ones at the same time, even though they didn't need to be changed quite yet, because "they're all back ordered and you can't even get after markets." I went home and ordered a pads on rock auto for about 20 bucks and installed them in about 2 hours. I wrote that to convey that the 300 dollar price at Erie is equivalent to the 140 price at Shults, and the only conclusion I can reach is that EITHER my car no longer required low conductivity fluid OR low conductivity fluid is no longer very expensive.

Good luck.
 
By chance did they indicate the volume of coolant used on the invoice? There's been some mentions of only small amounts used, far less than the total fill.

I'll add a third possibility to my two previous conclusions:
The blue fluid is still very expensive, but Hyundai no longer believes that a complete change is required at the first change.
The invoice has two numbers.
Tech - 67.60.
and
"Installed 00232-19113 : Electric Vehicle Battery Sy [email protected]" - 62.35.
10.40 tax.
Total 140.35

Obvious guess is that they put in one gallon of the stuff at about 62 bucks a gallon.

I really don't care, TBH - got it done. Coolant is resilient. I'm not worried about conductivity and slow-burn fires well after crashes. Life has risks. I'm putting this to bed. Maybe some future change will require 10 gallons at 65 a pop. Time will tell. Hyundai probably got tired of the complaining that they surely got when folks were being asked to pay one large for a coolant change, lol.
