Good Morning. Ah..ha! I have the same issue.
So my Kona is older than yours: birthday is Aug2019 and 14,000km on the clock. But the noise is only 4-5 weeks old.
I've listened very carefully to your recording several times this morning.
It has the same characteristics as mine: a ticking sound increasing with motor revs and disappearing at about 10km/h - so walking speeds only. Same rise and fall with minor throttle inputs.
Where it differs is that yours has more of a brushing sound and mine a sharper tick-tick-tick.
But my story gets a bit more complex because its intermittently there (of course it is). And I can't recognise any temperature relationship on its intensity. By that I mean sometimes its louder and sometimes softer (and when its softer its more of a brushing sound like yours). So I had it in the dealership yesterday, and of course the sound was gone by the time I had driven the 9km to get there (of course, happens every time). Notwithstanding, they put it up on the hoist and gave a thorough look-see. They said they could, maybe, hear a little sound. So we agreed I would monitor and whip it back in once it reappears.
My speculation is that after they did the 15,000km service (I went in early 13 months cos I had a charge-port door issue to fix), that was the time the sound first started up (suspicious?). It also feels to me like a motor-related cyclic sound (not wheels). Does anyone know what the rpm of the motor is at low road-speeds?
Still a mystery, but interesting to know someone else is having the experience.
Next time the sound crops up, I'll record it for you.
