Finally crossed 37,500 miles, and the 2020 Niro EV requires the electrical coolant (blue type low-conductive) to be flushed. Since I could not find any reference to anyone having this done before, I thought I'd leave this information for anyone searching for it.
No issues having the dealer perform the service. It cost $170 (plus tax etc), included fluid exchange and test drive...some kind of test or calibration was required after the service. I also had the brake fluid changed out at the same time, but it was all under 2 hours.
