How Do I Know if My GM Hitch was recalled?

I have an 2004 2500hd and have had no problems. I too was freaked out with all the posts. It's hard to explain but the ones that failed did not have a plate that mine has. You have the square reciever which is welded under a couple of vertical plates. Between the plates there should be another plate kinda filling the void. I think if you do not have that plate you could have a problem
