~37650 miles. '21 Ultimate. Purchased used from a non-Hyundai dealer out of state (pricing geo-arbitrage).

No problems. Newer tires on the front. Some sort of budget brand I've never heard of and can't remember right now. Still has the factory Nexens on the back. They are fine so far but noticeably louder than the front tires but then all new tires are usually quieter than worn tires. Prob due to rotate the tires. I won't be sad to replace the Nexen tires. Will prob just match the front tires. As I recall they were an Asian budget tire than cane be sourced locally through WalMart. The set after that I'll prob go with a name brand tire of some sort.

Good car. Great for ~200 miles this way and ~200 miles back. I've been using it for a commuter carpool car with my ever patient wife. She really likes it too. Good size for daytrips and parking lots. We have a larger V6 SUV that really shines as a travel car, but I don't really want to use it around town. I ran the Kona ~150 miles to my relatives house yesterday evening to help with some family stuff. And then same distance home around 11PM. Comfortable, quiet (except the rear tires), great stereo, and we like the driver's assist equipment.

Maybe next weekend I'll drain/fill the GRU. I have the supplies on hand. Just need a bit of time and weather.
 
55,000 mi / 90,000 km '20 Ultimate. 94% SoH - around 1% degradation per 10,000 km*
  • *Main HV battery replaced at 45,000 km due to recall.
  • Two gear reduction units (GRU) made rumbling noise. Two GRUs replaced under warranty.
  • Steering wheel made crackling sounds when turning past 3/4 radius each way. Oil residue found in motor compartment where steering wheel rod protrudes to and dealer confirmed the steering wheel assembly leaked oil. Fix (replacement) attempted by dealer and noise reduced but not eliminated.
  • Charging door lock mechanism (alongside the charging port) was replaced after an accident. New one failed to unlock 1/3 times (50-100 cycles) unless the door was bumped. Replaced by dealer.
  • Cabin motor started to make the faintest of squeeks between ~0-1 speed when set to AUTO. Replaced under warranty.
None of the issues caused the car to not be driveable. Overall I'm keeping the car for a long time.
 
2019, 20K miles.
-Propulsion battery replaced last year. (8 months without a car)
-Propulsion battery replaced again this year (2 weeks downtime)
-12v battery failed, I replaced it with AGM
-Reduction gear is gradually worse, now it has quite audible "wheel of fortune " ticking. Going into the dealer soon.
-One of the OEM tires had a nail, could not be repaired,
I have Michelin x-climates on it now. drives much better, no loss of range.
-This model does not have a heat pump, so the winter range is much worse than the summer range.

2022 Kona Electric SEL. 64000 miles. Only issue so far is dead 12V battery once when the car was very new.

Original Tires would be changed in next 15 days. I could get another 5000 miles perhaps on original tires. But I would change around 4/32 remaining as recommended by Consumer reports.

I have not seen significant battery degradation, apart from big seasonal variations here in northeast.
I was able to get 280 miles on a charge driven mostly on highways very recently. I could have gotten 300+ had it been more on local roads.

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.

@Kirby34 are those run flats?
 
2023 Kona Electric Limited (US), about 29,000 miles, two years old. Running the original Nexens and they're all at 7/32", so I figure the way I'm driving it I've got plenty of miles left on these tires.

More concerning is that battery SOH is reading 95.7%. It's primarily charged at home with a few fast charge sessions while on occasional road trips. All original equipment except for replacement of a wiring harness and connector after it wouldn't charge from any source 6 months after purchase.
 
To what SoC is it typically charged to and how far do you run it down?

What was roughly the battery temp when SoH was read and do you have prior historical values to understand the trend?

I've almost always charged to 70 or 80% and seldom discharged below 40%. Almost all charging at level 2 at home, occasional fast charging on the road.

Battery temp doesn't seem to matter, lately reading SoH at about 50 degrees F, it's the same lately in the 30's.

Last I looked at it, which was about a year ago, it was at 100% and hadn't moved since purchase.

2021 Kona at 78,000km. I have the same charging pattern. I only charge to 100% before long trips at home - 4-5 times a year. When I use L3 chargers - on long trips, 4-6 times a year - I charge to 90%. The last 10% - 90% to 100% - takes for ever. Overall I also think that the use of L3 charges is hard on the battery.

Hyundai 'invited me' to a BMS upgrade. Had it done last week. I wonder if this has something to do with the pending connectivity to Tesla superchargers. We should all have receive a NACS to CCS converter plug at no cost from Hyundai sometimes this year.
 
There has been a BMS update available since about Oct 2023 that fixes fast charging problems that many were reporting on other forums. If you didn't get that in the last 14 months you'll have it now. I only got mine Oct 2024 and like all BMS updates it zeros out all the BMS cumulative data relevant to the traction battery.
I've not seen any report of a NACS-specific upgrade.

That much the same as my own charging habits, noting that my battery pack was replaced Oct 2022. I'm still at 100% SoH (before and after the BMS update) but only have added 3,000 km on the new battery.
 
I also got a new battery in 2022. When we bought our Kona we became a single car family. What is amazing that we still drive around 18,000km a year. The 40-80% charging at L2 at home and few at L3 yearly the car still charges to 100% when needed. We are very happy with the Kona. Only had one problem; last summer the heat pump had a leak and the AC stopped working. Had it replaced under warranty in a couple of days. Our 5 year bumper to bumper coverage is good till the end of August. Hope the car will keep behaving after for a few more years. Now that I became 'senior driver' I see no reason to 'invest' in a trade.

Update/correction:
I took delivery of my car in 2020. I got my new battery in early 2021 not in 2022. Hence almost all of my driving was using the new battery. The dealership was aware of the free NSC to CCS adapter. But not on the timing of availability or the process of distribution.

2019 Kone Electric, 124,000 miles. No appreciable decline in charge or range (probably 90% of my charging done using a home Level 2 charger vs a DC Fast Charge). No rust. I replaced brake pads and rotors at about 100,000 miles, and Gear Reduction Fluid at 75,000. I recently has the Gear Reduction Fluid checked at the dealer (as they now inspect, then replace only as-needed) and they did not feel a need to replace at all (rare instance of a dealer not trying to make more money). I live in a cold, snowy area, so tires and floor mats have been my only recurring investments. The Nexen tires have not lasted that long for me. Nor has Goodyear Altimax. I do not baby the car. Trying Hankook's next. The Kona has been, so far, one of the two best cars I have owned in my 45+ years of driving. My biggest wish: a better on-board computer for determining remaining range.

2021 Kona Preferred - bought new in August 2020. My wife and I love this car!

Today the ODO shows 86,000km. Drive battery was replaced in 2021, the heat exchanger was replaced - leaked refrigerant about a three of years back. No other issues. Running on the second set of NOKIAN WRG3 all year tires and new 12V battery - 3 years back. Hyundai's 5yr bumper to bumper warranty runs our in a couple of weeks. I had my dealer to run an "end or warranty service" check. The only thing they recommended was break service - for ~C$600. I had the breaks serviced last week by my favourite, trusted mechanic. All components were judged in excellent shape only needed cleaning and lubrication for C$322.04 with tax.
The only annoying problem we had to date is three flat tires we had! One a nail puncture, but two of them were straight slash thorough the rubber. The Nokian tire warranty covered one 100%.

Overall our Kona is easily the best car we owned in 60 years of driving. I only wish I would get the promised Tesla converter plug.

I would expect that for that price the "brake service" $600 quote would have included cleaning and fluid flush/refill both of which I had done (at different intervals) on my 21 MY for a cost of $284.95 for the calipers/cleaning (Dec 2024) and flush/refill $207.90 (April 24) ...costs included tax and shop materials etc.
 
2021 Australian Highlander 64kWh, 36000km.

GRU replacement at 5000km. No other issues other than GRU fluid still gets black, but so far it is silent. Haven't checked traction battery SOH so cannot report on that. I use the supplied granny charger at home, charging to max 90%. At home never discharge below 25%. I do occasional long trips where it may run down to as low as 10%. On a DC fast charger, never more than 80%, except once to 100% where I needed the range. Original Michelin Primacy 4 tyres with plenty of life left.

Other than the GRU/oil issue, I love the car.
