The WeatherTech cargo liner for the regular Niro hybrid (not PHEV) fits perfectly in the EV. But, if you have the premium sound system, there is a small grate on the lower left side of the cargo bay, presumably to provide ventilation for the sub-woofer above it. The cargo liner covers this grate. I just cut a bit away to expose the grate. Also, if you are fond of using the tie down hooks, you will need to cut a bit away at the corners to expose them; there are ridges in the liner that make it trivial to know where to cut.
