I hope this is the right place for a general interest technical question. If not, I apologise ...

Can anyone tell me what is the purpose of the adjustable shutters in the front of the car? I realise there is a radiator of sorts there that needs air to cool it, so why the complication of servo-controlled adjustable shutters? Why not just open space to allow free flow of air?

Thanks in advance.

The batteries are typically controlled to be in a temperature range comfortable to humans - not too hot or not too cold. This is not just about cooling, it is also about keeping heat in on cold days. Therefore, the temperature control system includes the ability to let in cool air as well as keeping cold air out.
 
Call me cynical if you wish, but it's so complicated and labour-intensive that I would not be at all surprised if a dealer didn't do any of that and just replaced the fluid in the reservoir to make it look like the job has been done. Something to watch out for.

My son and I caught out a dealer doing just that on his conventional leased vehicle (not Hyundai). We reported it to the lease company and there was hell to pay for the dealer.

I always check the car carefully after it's been in the dealer's hands. After my 2 year service last Oct I pulled off each of the four bleed fitting caps and checked that they had signs of being removed and were wet inside. They did leave a single drop of fluid near the MC (thankfully on a plastic part) making me think they had fitted some sort of pressurised fluid fitting and it dripped on removal.
Overall I'd be surprised if the Hyundai importer did not enforce the correct equipment and procedures on their dealers as their reputation depends on things being done right.
Yes, for ICE I understand that it's not unusual for only the MC contents to be replaced, which of course is regrettable behaviour. It's probably not helped here in NZ that Kiwi culture doesn't seem to accommodate maintenance that appears optional and the benefits to caliper life is underappreciated. When I buy brake fluid at Supercheap I have to dust off the bottles on the shelf to check the dates, often expired.

I have to wonder if there's a DIY-friendly method of doing this such as just carrying out a normal flush perhaps twice as often and ignoring the other more complicated parts. After all, the purpose of the video was to eliminate noises due to entrapped air and so the procedure is intentionally thorough.

Hi KiwiMe, Off topic I know but....I'm travelling from Wellington to Auckland this Sunday via Napier and am planning the charging stops. We are going to a Climate Change and Business Conference and one of our group lives in Napier hence the route. I see a picture on Plugshare of what I think may be your Kona at Greenmeadows? Planning on a charge-up there and then again at Tokoroa.

John, I sent you a “conversation” as it’s called these days. Let me know if you don’t see it.
 
This information direct from owners manual for 2025 Kona EV Hyundai recommended lubricants and capacities:

Recommended Lubricants and Capacities

To help achieve proper vehicle performance and durability, use only lubricants of the proper quality.
These lubricants and fluids are recommended for use in your vehicle.

Gear fluid 2.8-2.9 ℓ (3.0-3.1 US qt.) HK ATF 65 SP4M-1
Coolant 13.5 ℓ (14.2 US qt.) Mixture of antifreeze and water (Phosphate-based Ethylene glycol coolant Battery for aluminum radiator)
Brake fluid As needed SAE J1704 DOT-4 LV, FMVSS 116

IIRC the gearbox fluid in the gen 1 was a little over 1 U.S. quart, the quantity has basically tripled in the new gen model.
Also note the coolant is no longer the low conductivity type (as we have discovered earlier) allowing for less material expense when the time comes for replacement.
