I don't drive a lot, so I just passed 16,000 miles on my 2020. I've had two problems: The charging door refusing to open at about 14,800 miles, fixed under warranty, and recently a buzzing noise from the driver's door lock when locks or unlocks -- which is supposed to be fixed later this month.

2021, 26k, just got the coolant update [I think, the relevant parts looked completely untouched and the service
manager got super-defensive when I asked what was done]. Just plug-patched the second tire problem
on it. On my third fill of reduction-gear oil. I do wish it had come with the battery heater, as charging a
cold pack is no fun.
I'm a little more eager about whenever the next roadtrip comes along, with the improvement of taking the
whole shotgun seat out for more bed and storage space.

It's shame we don't have a battery pre-heat option, presumably an easy software addition. But if it's any consolation, I’ve read of two incidents where the battery heater internal fuse melted. In the one case that caused a loss of HV isolation triggering the dreaded 'check electrical system' warning.
Powertrain noises are now being reported as frequently as ever with one Ioniq 28kWh owner having to purchase a new GRU himself. His report and internal photos of the old one are here.

2021 Kona, picked up new on 2020 August 31. Current 'milage' 54,650km.
- EV battery replaced under the battery replacement program (warranty)
- Blue coolant was replaced (warranty)
- Two flat tires - no spare is a pain. But I had total of three flat in 52 years of driving.
- Recently - last few months - observing some repetitive noise related to speed. Not very easy to hear but it is there. My EV is no longer completely quiet! Best to observe when travelling on recently paved roads where the tire/road noise is minimal. At low speeds is an electric motor 'humm', at 80km/h start sounds like a wheel you spin with spikes on a country fair to win something. I checked with my tore dealer, it is definitely not caused by the tires.
Others had similar issue with their Kona EV. Apparently there is service bulletin out about this noise, covering a range of cars.

That would be the GRU and or motor, definitely have it investigated with this TSB in hand. Fortunately, your car manufacture date is within the specified period to 1/19/21.
The earlier, the better, as replacement parts may take some time to arrive.

Actually I am taking her in for 60,000km service tomorrow. I already told them to check it out. It is very faint, but definitely a new sound. You really have to listen to it while driving on new pavement or the road/tire noise will mask it pretty well. I don't hope too for much, but at least the issue will be on record.

Update --- 2023-09-03
I picked a lousy day for the 60,000km service appointment. It was raining all day. The tech offered a test drive to check the reduction gear noise. The test drive was inconclusive. The road noise (tires on wet pavement) completely masked the faint transmission noise I was complaining about. However, I have now the issue recorded on the service record on my car. The tech suggested to keep driving the car and try to record the noise and take it back when the roads are dry. He will be happy to test drive it with me. I will try to do this on a good quality pavement and dry road.
Just a note here. To my surprise I had no push back or questioning of my claim. The tech said that he "needs more evidence to have an order for a new tranny approved". That statement indicates to me that they are aware of problems with the reduction gear.
However, when I suggested to change the reduction gear oil, just to see what happens there was a slight push back. The tech suggested that they will do it - at my cost. But he said "why waste money"? The reduction gear assy is warranted for 8 years. and the maintenance schedule does not call for it for now.
As a final note we still love our car! No intent to trade it.

Just passed 78,000 miles.. still runs like new without any major issues I think. I think I should do the reduction gear oil my next service though, but not sure what else. Anyone hit over 100k miles yet?

2019 Bought used, now 44Kmi. Drivetrain / warranty fixes shortly after purchase, batteries were already replaced just before. EV charging door has been sticky, there are pressure/stress issues with this assembly. Compared to the ICE vehicles I've owned the problems are not even close. I really like the car, any issues are minor.

22/23 Kona 65,000kms. Few issues. Waiting for dealer to obtain equipment from Hyundai for coolant change. Have some suspension squeaks I'm not happy with but we are remote rural.

Not a problem, per se, but at just over 28k miles, I replaced the original Nexen tires with Hankook Kinergy GT's. I was at 4/32, so I could've gone a bit further, but considering I developed a very slow leak in one tire after running over some sort of roofing "tack", I figured I might as well pull the trigger. The initial ~27k miles were about 85-90% freeway "at-speed", meaning I dealt with very little commute traffic due to an off-shift.
For the last 18 months, after changing shifts and using the work bus to commute, my driving has completely reversed so that definitely more than 90% is on city streets or short stints (<2 miles) on 45 mph expressways. We'll see if there's any appreciable change on the GOM after a few 20-80% charges, though because of how little I drive now, that may take at least a couple months. Haha.

This past Sunday, I took my longest single-charge trip in the 3+ years I've had my Kona - 223 miles round-trip (~375 km). This was a good time to assess the new Hankook tires. To me, the ride was much better and road noise much less noticeable vs the original Nexen tires and this was a direct comparison because part of the trip was on the same ~40-mile stretch of freeway I was using for my work commute.

Any sense of whether the tires impacted your range and energy use?

I think "low-rolling-resistance" tires are gimmicky. On a test harness under controlled ideal conditions you might notice something, but in the real world just put reasonable tires and I don't think you'll notice. I put some lower end grippy Lexani UHP's on mine, I live in AZ these are 40K warm weather tires. Better ride, better handling, just plain better driving experience, and I didn't notice squat on the range. Would you really notice a 5 mile improvement with all the other variables that affect range? Driving from here up to the high country I made it to the charging station with roughly the same leftover range as always. I'd rather not squeal tires turning a corner or taking off a bit too briskly, than get some mythical 5ish extra miles of range.
The 2020-2024 MINI Cooper SE is not very aerodynamic, and it has a tiny 32.6 kWh battery. Understandably, MINI wanted to maximize the range of this car without compromising the brand's reputation for excellent handling. Somehow, MINI found tires that balanced these contradictory requirements wonderfully.
I'd love to know how MINI chose certain summer performance tires from three manufacturers, Goodyear, Pirelli, and Hankook, that offer more range than any replacement tires MINI forum members have tried. The forum members have found stickier tires, but none have found tires that corner as well as the OEM tires and also offer greater range.
An even more amazing benefit for me is that my Hankook Ventus S1 EVO3 tires rarely squeal when cornering. They make my MINI Electric the perfect stealthy tool for navigating city streets when time is at a premium.

While it's only been a few weeks, I'm going to say there has been no huge impact, either way, to the energy use. On workdays, I have a ~3.5 mile (5.6 km) drive to where I catch the company bus and the amount of time and speeds are very consistent in both directions. While I don't keep close track of the consumption numbers for those trips, I know they're definitely not lower. If anything, they may be slightly higher because I don't recall seeing as many results consistently around 5.5 mi/kWh.
