Being a mechanical engineer, one can tell when something is of high quality and excellent design. I purchased this hitch for a 2020 Kia Sportage 'S' the installation instructions were spot on (I actually got a great tip from etrailer on how to remove the rubber mount on the muffler) The welds were excellent as well as the finish and the price was great. The last hitch we bought was warped from the heat of the welds and took some strong arming to mount it to the frame. This hitch slid right up into the frame with no scraping scratching the paint of the frame. The indented use for this is a Allen 4 bike carrier. BTW, the picture shows the hitch tilted up - it is NOT, that's the angle of the camera

Kia Sportage

Thanks for the fast shipping an excellent installation instructions. The installation was as simple as advertised!

I installed the Curt hitch on my KIA Sportage in about 30 minutes, solo, thanks to etrailer’s clear video and instructions. I could have done it little easier with a helper to hold the hitch up for me while I started the bolts – but not a hard job solo ( I’m 61). Thanks again; you’ve earned my business.

Definitely a 2 man job, but it's holding up great! I recall the bolts being a little tricky to line up, but they all worked out once they got started.

Still works great after many uses in the past year.

by: Stephen 06/22/2021

Disappointed that only 5 of the 8 bolt holes on the receiver, 3 on driver side, 2 on passenger side, lined up with the welded nuts in the frame. As the receiver will be holding a bike rack and not doing any towing I am not too concerned. For what I paid I expected a better fit.

Thank you for your review. This hitch receiver sounds like it has a flex problem but it is a relatively simple fix. Please see the attached help article:

Great purchase;. Avoids having to store bike inside my KIA Sportage. Bike rack attached perfectly to 1 1/4 receiver. A friend who is a mechanic only charged $40 to install in less than an hour.

Hitch is exactly what I had hoped it would be. Sturdy, easy to fit various bike racks and cargo carrier.

by: Michael 08/31/2021

2022 Kia Sportage

The Hitch itself is of good quality steel. Very sturdy. Looks like good welds. The installation was easier enough. I have a 2022 Kia Sportage and followed youtube instructions as well as etrailer video instructions. I did do this by myself so it took a little effort to hold the hitch in place but was able to get my bolts started. I did have one issue though. 3 of the pre-drilled holes aligned just right, but the 4th is about a 1/4" to low. My mounting hole on my vehicle frame is just a tab bit to high. I couldn't get that 4th bolt in. I found a work around so it's on there very solidly. It's a very low profile hitch. You can only see the receiver part of it sticking out from under the vehicle. Looks very nice.

2017 Kia Sportage

This is the 3rd hitch I've installed from etrailer and again I'm very happy with the ease of installation and the information available. I viewed the video the day I ordered it and while the installation lying on your back on a lumpy driveway isn't that easy we had no problems to mention. We have another vehicle to install a hitch on and I'll be ordering from here again.

2020 Kia Sportage

Everything was right on only glitch was a mounting hole on the left side, side mount rear hole was a 32nd of an inch to low and had to be drilled out. Wire harness was right on but directions to generic, should be more specific to the vehicle harness was ordered for.

by: Rod V 05/17/2017

Was surprised on how quickly the order was delivered. The hitch and wiring component have been installed and work great. Extremely satisfied with the service.

My husband was able to install this on our vehicle in an hour after watching a video on how to do it. Saved $ from having to have someone install it for us. Haven't used it to pull yet, but we'll find out in a few days!

Great customer service and easy to order. Delivery faster than expected but when it was delivered was broken open on one corner of box which was done in transit. I opened up box and it appears all is good with the exception black paint scuffed off. I would order again for sure !

They should make the mounting holes a little wider for some wiggle room when mounting it.

Great receiver. Had to file one hole a little but installation was fairly easy.

Do you have a question about this Trailer Hitch?

Would Hitch for 2023 Kia Seltos Also Fit 2021 Kia Sportage
The vehicles are different enough that you would not be able to use one hitch on both vehicles. For the 2023 Kia Seltos you'd want the Curt hitch part # C65FR and then for a similar style of Curt hitch that fits your 2021 Kia Sportage you'd want the part # C12158. Also worth mentioning is that hitch install hardware is one time use so you'd have to buy new hardware if you could swap hitches.

Will Trailer Hitch from 2014 Kia Sportage Fit a 2019 Kia Sportage
The 2 Curt trailer hitches that fit a 2019 Kia Sportage are the Class II # C12158 with the 1-1/4" receiver and the Class III # C13281 with the 2" receiver. Since these do not fit a 2014 Kia Sportage you will need to swap out the current Curt trailer hitch that you have. These do, however, have the same hidden crosstube design so you still get that clean looking installation (see attached photo). I recommend going with the Class III option, part # C13281, as it has a higher tongue weight...

Will 2020 Kia Sportage Work with Kuat NV 2.0 Base 2-Bike Platform Rack
You should be good to go with the Kuat NV 2.0 Base 2-Bike Platform Rack - 1-1/4" Hitches # BA12B with your 2020 Kia Sportage! When we installed the Curt Class II 1-1/4" Hitch Receiver # C12158 on a 2020 Sportage we measured 5" from the center of the hitch pin hole to the rearmost part of the bumper and the NV 2.0 measures 7-7/8" from the center of the hitch pin hole to the closest part of the rack when it's folded up. If you have a different hitch receiver just make sure you don't measure...

2022 Kia Sportage 1-1/4 Hitch or 2 Hitch for Heavy e-Bike
As long as the trailer hitch tongue weight rating is high enough you can use the Curt 1-1/4" # C12158 or 2" # C13281 receiver for your 2022 Kia Sportage. The 1-1/4" has a 350 lb tongue weight while the 2" has a 525 lb tongue weight - keep in mind that the Sportage might have a lower tongue weight than either option which would then make it the limiting factor. I usually recommend going with a 2" hitch because there are a wider variety of accessories for the 2" than the 1-1/4" option. For...

Will the Curt Trailer Hitch Receiver # C12158 Fit Both the 2017 and 2020 Kia Sportage?
The Curt Trailer Hitch Receiver # C12158 is confirmed to fit all trim levels of the 2017-2021 Kia Sportage. If you are transferring this hitch from a different vehicle I recommend using new hardware. The Replacement Hardware Kit for Trailer Hitches # RHK will allow you to order a new set of hardware specific to your hitch. Both the Curt T-Connector Vehicle Wiring Harness # C56321 and Tekonsha T-One Vehicle Wiring Harness # 118698 will also fit the 2020 Sportage if you are needing to transfer...

Will Thule Hitching Post Pro Work With Class ll Hitch On 2017 Kia Sportage
The Curt Class ll Hitch # C12158 we offer for your 2017 Sportage is capable of carrying 4 bikes. The note about Class l hitches does not apply to the # C12158. The Thule Hitching Post Pro # TH934XTR will work with the 1-1/4 inch receiver you have on your vehicle. The bike carrier does have a weight capacity of 35 lbs for each bike. If you are planning on carrying bikes with alternative frames like kids bikes or women's bikes I recommend using an adapter bar like part # 64005. This attaches...

Mounting Bracket for a 4-Way Trailer Wiring Harness on a 2017 Kia Sportage
Neither of the Class II hitches for your 2017 Kia Sportage come with a wiring harness mounting flange. The one you see is on the etrailer Class III hitch # e72TR. There are many mounting brackets that you can use though. Whether or not the wiring can be run externally on a given vehicle is a product of the vehicle itself and how the harness installs. Basically on affected vehicles if there is a grommet somewhere in the bottom part of the cargo area through which you can route wiring then...
