I just put a hitch on my wife's new Fiat 500. Holds 3 bikes no problem. I ahve a hitch on my Scion Xb. With the hitch rack and my Thule roof rack, I can carry 8 bikes. If these two small (the Fiat is really small) cars can safely carry bikes on a hitch mount rack, the Genesis will have no trouble. BTW, I order the hitches for all my cars from etrailer.com- good prices and very good installation instructions. I have ordered 3 from them so far, and they have never taken me more than 1/2 an hour to install. The hitch rack can be locked to the hitch, and the bikes can be locked to the rack.
