My lady and I both have 2018 MY cars.
In the Toyota manual, it says nothing about brake fluid changes only "inspect" and "dealer may recommend services based on inspection." Translation to me is: we dont want to raise our maintenance costs on paper, but you probably need it.
In Kia manual, it says nothing about brake fluid either, except inspect at 30k. Similar likely outcome.
I'd say 3-4 yr is a good interval.
