Probably, but not the best choice. They mention towing package (has to be ordered that way) in several markets but I'm not sure they have ever delivered one. Presumably it would have a higher capacity radiator and perhaps brakes. If you have an engine failure, especially from overheating and they see your trailer hitch they may void your warranty.
Most posters who discuss hitches for the Niro and Ioniq want them for bicycle racks.
