The Thule website just shows rack systems that hold onto the edge of the bare roof and not the flush rails.
Strange that Yakima said to ask KIA. I think the flush roof rails are the same on the EV, regular hybrid and the PHEV. The Yakima website shows 2 expensive rack systems that attach to the 2023 Niro flush rails--called the Sightline system. Just go to the Yakima website and put in 2023 KIA Niro. It looks like the appropriate SightClip 25 is out of stock.
