I have an email out to the Curt Hitch company regarding this. Etrailer.com says you can use Curt 13329 on the Niro PHEV. I don't think there is anything physically different. I will post a message when I hear from the horse's mouth. I also requested an alternative if indeed the 13329 doesn't work. I have seen the video of the install and it seems pretty straight forward regardless of what model you have.
