I don't know what the future holds, but I am at the mileage you are considering and it's been going just fine, so my expectation is that it will be just fine at least for the next 50 000km. While it depends how much you will be paying for and what you will be using if for, I don't notice a difference in how my car behave between 2018 and 2025. More details below:
I am currently at 154 666 km (96,105 miles) with a 2018 Niro FE, living in NE. During the first 3 years I didn't didn't drive must (commuter rail during weekday, Niro during weekend). For the past 4 years I average 60 mi (96.6 km) daily, and rarely have a day of the week or weekend when I don't drive. I still get 60 mpg during the summer and 45 in winter (3.92 and 5.3 L/100 km, respectively).
Besides regular maintenance appointments every 7,500mi, all done at the dealer where I bought the car, since they're great, I had the breaks changed once year 4 because of rusts due to the car not drive much. Earlier this week at my 90,000mi maintenance, they said the breaks looked great when asked. I also just had them install my second set of tires, (Yoko Avid Ascend GT, noticeably better handling than OEM Michelin, but I think I am experiencing a 5 mpg drop). One of TPMS sensor went bad so they put a new one ($45). They told me one of the rear camber/caster/toe bolt is seized, so they couldn't align it to 0 degree, but it's barely off and should not notice any impact. But next time I need an alignment at the 120,000mi appointment they will have to change both (~$220 ea). Since most Americans change their car at 100,000mi they assumed I would do the same. Not so fast...
Other small things:
My 60lbs daughter broke the handle on the passenger door, just based on how she's been pulling it to get in, so they fixed that. That's a known styling issues with Kia/Hyundai handles.
One of the rear positioning light went bad a couple years ago so I replaced both, myself.
I detail my car 3-4 times a year. I wish I did it way more often, but I don't have time or a garage. In parking lot, my car paint still looks better than an equivalent old car whose getting the Scrubadub/car wash treatment. Kia/Hyundai's paint is pretty soft, average in thickness, so not the best but it's looking good so far.
I only fuel at stations with Top Tier gas.
The only two times I have used the sport mode was to force the compression while going down a very steep hills while on vacation. Otherwise, in Eco mode, flooring the pedal gets me from a side street into a 50 mph blvd with Boston drivers at 65 mph traffic just fine.
