Looks like Curt makes one, there is a difference between sedan/hatch...so make sure you pick the right one. The also seem to have a wiring harness, but I'd consider relay isolation and a separate fuse for the power to the trailer. Keep in mind, GM advises not towing with this car, so it might be a warranty problem (though I'm quite sure it can tow a small trailer, less than 1000# no problem). Use of the hitch for a bike rack or something similar should not be a problem for the warranty.
After looking at one for my sedan, I found there are both Curt and DrawTite. The Draw Tite look a bit more involved to install, but seems to be more sturdy, and lower cost. If I had a hatch, I'd try this one:
