Known issues

Low
Kia caps DC fast charging at 85 kW, so a faster station saves little. Its spec sheet lists 45 minutes to 80 percent on a 100 kW charger and 43 minutes on a 350 kW one.
Low
The heat pump is not standard on either trim. It comes in the Preserve package, and only the Wave's version of that package adds the battery warmer.
Low
This is a different pack from the 64 kWh one in the 2019-2022 Niro EV: 358 volts against 356, an 11 kW on-board charger against 7.2 kW, and vehicle-to-load capability the earlier car did not have.
