Hmm. I've driven on snowy roads and found it to be better at handling than any other car I've driven, even counting cars that had dedicated snow tires (whereas the Ioniq only had all-season tires).
It also has a "snow mode" to help with particularly bad roads. I found at least one review that puts its snow handling down as a "pro", so it's not just me. [1]
I did get the Limited AWD with the 20" wheels. Not sure if that makes a difference.
