I got the class III so I could use a 2'' hitch. Installing it this weekend to use with a bike rack. Kia Netherlands I believe has hitches as accessories but they aren't official Kia Corporate accessories.I ordered the Curt Class I universal mount bike hitch from carID and took it to my Kia dealer to mount it. They said it wouldn't work, so I'm having to return it. I don't know if any of the hitches listed by etrailer.com will work or not. I'm a bit skeptical, as they are Class II and III, which is way overkill for the Niro. I'm hoping that Kia will come out soon with a hitch for bicycle racks.
Warranty Worries are stilla question after talking to KIA Customer Service.
I asked if either installing a hitch or pulling a trailer would automatically stop the warranty.
The rep said, good question and went off to check. Came back and said Operators Manual (Page 6-88) says Trailer Towing not recommended.
However, he said neither installing nor towing would void warranty but realize the car is rated at 840 LB. I think he said 840 lb load total including the trailer and what is in the car. He stated of course a bicycle rack would not add any significant weight.
The warranty would be based on diagnosis (and you know who does that) at the time of need for a failure of whatever.
MY COMMENT - It remains a question to an extent. Having a hitch on there might give them a chance to void warranty or at least consider it. Personally, I don't think it would be a problem to have a hitch. I would not want to pull anything heavier than a couple hundred pounds.
