2019 Kia Niro

I purchased this hitch for the primary use of attaching a bicycle rack. I am completely satisfied with this purchase. The construction of the hitch is very high quality and it came with all the necessary hardware, even included is the fishwire for the large bolts. The instructions were very clear and the fit was perfect. I installed the hitch in less than hour by myself. The only thing I did different was to cut a 5 inch notch out of the factory metal exhaust guard so I could reinstall it. After doing this the exhaust guard does not contact the hitch and there is no interference. You can not reinstall the exhaust guard without doing this. The instructions say to leave it off but I figure there is a purpose to the exhaust guard so I chose to reinstall. Fast shipping from etrailer was great too! Highly recommended!

2021 Kia Niro

Excellent instructions and etrailer videos. A friend and I installed this on a 2021 Kia Niro Touring Hybrid in about 45 minutes, and the "pro" guideline was 40 minutes. I had to call etrailer before ordering to confirm fit, as the local hitch shop had told me it would not fit while etrailer's catalog said it would. Customer service on the question was excellent and they assured me it would fit. The proof is in the photos accompanying this review. I couldn't be happier with the outcome.


I've been using my C12171 hitch receiver for my bicycle rack for the past year and am very happy with it. Since my 2018 Kia Niro PHEV is not recommended for towing, this is my only use for it. My only other comment is this is a Class II receiver, which is overkill capacity for this application. I would have been even happier if there had been a Class I receiver available to fit on my vehicle, since it would have been less dead weight impacting my fuel economy.

2017 Kia Niro

I followed the video and proceeded with install on the 17 Nero. I was worried it would be too much for me. Not an issue… all work I did was on my back without jacking up the car. Total job literally took me an hour sand a half. Instructions were ample and precise. It was a great buy


This hitch has been excellent and trouble free since I bought it a year ago. It's simple, easy to install, durable, and I got a great price from with super fast shipping!

Fantastic! I still love it!

2019 Kia Niro

I have use eTrailer for many projects. They are fast delivery and easy to purchase from.
Haven't put the hitch on yet not sure if it fits but my other purchases have fit and easy to install.
Love their videos on the product installation before purchasing

Mark - 01/08/2021


Product did not include the correct bolts. The Kia Niro requires four M10x1.25 30mm bolts, but the hitch came with four M10x1.5 30mm bolts. If you try to install the included bolts, it will damage the nuts welded into the car frame. The instructions that came with the hitch list both bolt sizes in different sections, which match the instructions posted on this site. I can not recommend this product until CURT provides the correct bolts.
The product arrived as scheduled and in decent shape. It sits below the bumper, so you don't have to cut the plastic bumper cover, but you do have to cut a significant amount of the under-body plastic. You also need to permanently remove a protective metal piece from the exhaust, although I'm not sure what its purpose was.

We can get the hardware for you. Please give us a call at 800-298-8924.

2017 Kia Niro

Easy install, but I also fully removed the muffler considering it was just two nuts to prevent unnecessary stretching of the other hangers. The instructions point out removing the heat shield which at first glance I did not realize was the horizontal metal piece which is installed on the aft end of the muffler. Only problem was that when installing the horizontal M10 bolts, one of the welded nuts inside the frame rail broke off when torquing. Would recommend running a tap to clear the threads prior to lifting the hitch as well due to the undercoating sprayed on the car and dirt buildup. Have not towed or attached anything to it yet.


Excellent service when I called shipped right away got it earlier than I thought very happy

2018 Kia Niro

Customer service has been above & beyond in keeping me aware of the availability, delivery schedule, etc. Installed nicely. Solid construction. Looks unobtrusive - like it came factory ready from the car dealership. Very happy. Would purchase products from this company again.

2017 Kia Niro

1st - The hitch was exactly as described, fit perfectly and was relatively easy to install using minimal tools, and I installed it alone.

The customer service was PERFECT!

It arrived on time!


Everything is perfect

  • Recommended Bike Rack For 2021 Kia Niro PHEV
    I do have an alternative option for you, but there is not currently a trailer hitch receiver available for your 2021 Kia Niro PHEV. I recommend the Yakima FullBack 2 Bike Rack - Trunk Mount - Adjustable Arms # Y02634 which is a confirmed fit for your Niro PHEV and will allow you to transport up to two bikes weighing in at 35lbs or less. While this is not the hitch mounted carrier you were expecting, this is a very viable option to still allow you to carry your bikes. I included a video...

  • Trailer Hitch for a 2022 Kia Niro Plug In Hybrid
    I would be happy to find you a hitch and help clear up the confusion regarding our fitguide. We get updated information throughout the year on newer model vehicles and the hybrids are typically the information that changes the most. I checked with Curt and we do have a hitch for your 2022 Kia Niro Plug In Hybrid. It is the Curt Trailer Hitch Receiver item # C37BR. This hitch is custom fit and bolts directly to your Kia with included hardware. This is the only hitch that Curt or anyone else...

  • 2017 Kia Niro Hybrid Trailer Hitch Receiver and 4-Way Flat Vehicle Wiring Harness
    Yes, the Curt Trailer Hitch Receiver # C12171 is confirmed to Fit your 2017 Kia Niro Hybrid. This class II receiver has a 1-1/4" receiver tube with a weight capacity rating of 350lbs of tongue weight and 3,500lbs towing capacity. Be sure to check with your Kia dealer for your exact towing capacity and use whichever rating is lower. We also have the Class III 2" Curt Trailer Hitch Receiver # C13329 that is confirmed to fit your Niro. The larger receiver will give you a larger selection...

  • Trailer Hitch Option for 2021 Kia Niro PHEV
    It will not, unfortunately the trailer hitches we offer for the 2021 Kia Niro aren't compatible with plug in hybrid electric vehicles A/K/A PHEV's as the structure at the rear of the vehicle is different enough that the hitch won't fit. If you were needing a hitch to carry bikes, I'd recommend a trunk mounted bike rack, like the Yakima FullBack 2-bike model, part # Y02634 or for a 3-bike model, use # Y02633. I've linked to a demonstration video for the Yakima FullBack trunk mounted bike...

  • 4 Bike Rack Recommendation for 2018 Kia Niro
    Sounds like you are getting a lot of conflicting info on fitting a 4-bike hitch rack to your 2018 Kia Niro. I can help you accomplish carrying a 4-bike rack with your vehicle but we do not offer a 2 inch hitch for your vehicle. Reason being that 2 inch hitches are only used typically on larger vehicles with heavier capacities. But since the Curt hitch for your vehicle part # C13329 is a Class II it can allow you to carry a 4 bike rack. Only issue is that none of the Class II 4-bike racks...

  • Trailer Hitch Fit for 2022 Kia Niro PHEV Plug In Hybrid
    We do indeed have a 2 inch hitch that works with the 2022 Kia Niro PHEV. You'll want to use the Curt 13497 Class III hitch, which we carry as part # C37BR. If your Thule rack is compatible with a 1-1/4 inch hitch, you'll want to use a reducer sleeve like # e63YR. I've linked to the installation instructions.
