I installed the Curt hitch a couple weeks ago and a few notes:
- I did NOT fully cut off the trim piece per the instructions, instead just cut about a 3/8" slit the lengthwise which allowed it to straddle the vertical support bar for the hitch and allowed me to reinstall the rest of the trim piece so that there is no gap. Not sure if it makes any difference but just my preference. Took a little trial and error though.
- The Curt hitch also hangs about 9 inches off the ground on the sides and 9.25 in the middle I'd say. I don't think they will come out with a flush mount hitch for this like I have on my Subaru or as other have mentioned was available on previous generations of the Honda.
- While 9" is fine, where it matters is if you have a 4-bike rack that hangs 4 feet off the back of your van and you are going up or down steeper inclines (i.e. backing out of a driveway). I had mine loaded up in this situation and at the lowest point maybe had about 2 inches of ground clearance between the lowest point on the bike rack and the ground, so be careful!
- Personally I don't see the value in the Kia hitch unless you somehow negotiate them to install for that price. The Curt was $200 total, including tax and shipping, and about 2 hours of my time to install. Neither of these includes the actual harness to hook up to the lights so that is a separate cost unfortunately.
