Not much can go wrong with a hitch receiver if you're only going to use it for a bike rack. Only thing I can think of is the reduced ground clearance on your tail end especially if you have the trunk loaded up plus a couple or more bikes on the rack. That would be true with any brand of aftermarket hitch receiver though.
My wife's Limited has the OEM receiver but we have a Curt on our minivan. We have taken it on many road trips totaling thousands of miles with our hitch mounted cargo box filled to the max capacity of 150 lbs and a trunk full of luggage. Never have had a problem with the receiver.
