How Do I Know if My GM Hitch was recalled?

Although there have lots of complaints regarding the round OEM hitch from my searches there has not been any recall. I do inspect my hitch regularly and it does show any signs of failure. It has been suggested that some of the failures were related to rust possibly from salt on roads. That may be why I have not had an issue. All of that being said I have noticed that the hitch does have more flex than what I would like. That being the case I have been uncomfortable using it. My solution was to order a Curt replacement. I settled on model 15321 and purchased it from HitchAnything.com. Was 189.00 with free shipping. Arrived within a week and is currently sitting in my garage waiting for me to recover from recent surgery to install it. I have inspected it and it is much beefier than OEM.
