Just called the dealership back after they forwarded my video to Hyundai Australia. I had hoped that my recording was going to be enough, and that's what they told me, but now they want my car in for more tests, including some battery out tests. Has anyone had that happen to them?

First time that has been posted for this type of drive train issue, should have nothing to do with the pack ( I assume you are talking the pack, not the 12 V accessory battery). The order of repair is (according to my dealer) is (1) turn the motor shaft 180 degrees, (2) replace the motor and finally (3) replace the gearbox.

Wait. They're referring to an "engine" and "oil". Are we sure this is even a Kona EV?
I've driven almost 5000km since I first heard the noise and my car worked fine.

It was in a Kona Electric Facebook group. I assume they're calling the motor an engine and the gearbox a transmission.
Now I wish I'd have linked to the group. I'm pretty sure there was more context to make it clear it was an electric Kona.

It looks like the report from Poland of which I posted a screenshot a few months back.

I made an appointment for next Monday to take my car for a test drive with a technician to listen for the clicking sound. When I mentioned all the info I got on this and other online forums, they didn't seem too impressed. I'm also not too confident that the dealership has much experience with the Kona Electric. I just hope they do the right thing and contact Hyundai regarding the problem rather than writing it off as "normal". Is there anyone in the US that's had the problem fixed? If so, I'd like to share the name of your dealer/contact with my dealer in the hopes that talking to someone with a little more experience will lend credibility to my complaint. Any other suggestions on how I can get them to take this seriously?
Hopefully yours isn't as intermittent as mine and it actually makes the sound when you bring it in. I just got reminded this morning for the first time in several months but of course it "disappeared" after a lengthy drive

Now that my Kona's noise is pretty much constant since they" fixed it" doing the 180 degree engine shaft maneuver I kinda wished it was just intermittent like before.Hopefully yours isn't as intermittent as mine and it actually makes the sound when you bring it in. I just got reminded this morning for the first time in several months but of course it "disappeared" after a lengthy drive
My service department claims they are waiting on HYTAC to approve the next moves, its been 2 weeks since my last visit and nearly 3 months since I first reported. I understand COVID and all but for Pete's sake they seem to be in no rush. I sent a complaint to Hyundai Canada today maybe that might a fire under someone to get crakalakin.

I can probably get it to make the noise, but it's not very loud so my concern is that they won't hear it or will not take it seriously. The higher speed "rumbling/revving" sound is also getting annoying but, again, not overly loud.Hopefully yours isn't as intermittent as mine and it actually makes the sound when you bring it in.

The ticking sound at low speed is never very loud, but it is distinct and can't be ignored. The first time I brought it in, it took a few trips around the dealer's parking lot for the tech to be sure it was not normal. That's when they replaced the reduction drive. That only worked for about 400 kms before it started ticking again, but very intermittently. I reported it to them right away, but I waited a couple thousand kms before I took it in again. And I was lucky, as it did again while I was there, and the tech recognized it right away this time. They ordered the motor replacement, and two weeks later the replacement was done. So far so good, but only a couple thousand kms on the new motor so far. Will have to give it some time and see (and hope) this fixes the problem (whatever it was).
It surprises me that they just don't change both for that very reason, why have one component changed just to have the second replaced a short time later.

I guess I have my doubts that Hyundai has fully diagnosed the problem. Then again, when you consider how much these parts cost, it is likely that there is a lot of management pressure to try cheaper things first.
If these parts are supplied to Hyundai by an independent manufacturer than Hyundai should be going after them, maybe this is where a lot of delay is happening. Also if these parts were supplied with specifications that Hyundai originally provided and they fail to live up to that specification, than Hyundai alternately could source from another supplier. The cost of the installation is also not cheap with many hours of labor,
time and inconvenience of the customer, as well as reputation of Hyundai itself. I do give Hyundai credit for taking the initiative to address the problem, but we did pay prime dollar for these cars as well as a long wait for delivery. Does the additional cost of replacing all affected parts at one time not seem to be justifiable?

We could be relatively confident the motor comes from Mobis, since that is what they do and are part of Hyundai.
The gearbox supplier is unknown, but at best it could have been designed in-house by their drivetrain team.
There is a glaring design risk present that I would describe as “geometric over-constraint” when the two parts are coupled.
It’s pretty obvious to me because I‘m familiar with the relevant engineering principles.
Both the Bolt and Tesla cars avoid this pitfall with obvious intent. The Leaf is similar to the Kona/eNiro but somehow avoided getting stung.
The only certain fix is a redesign of the gearbox, IMO of course.

I dunno, it may have just worked. I just got an email from my service advisor HYTAC just approved traction motor replacement, its on order with no current ETA.
So far I have found my 2 communications with Hyundai Canada have been met with prompt and positive responses.
