That is pretty concerning that both failures happened at a bend. Seems at first glance to be a design fault, too sharp of bend/thin material or needs gussets.
I usually don't jump on the recall bandwagon, but if these were both 8000lb rated hitches and weren't overloaded/abused, I think Thor should get involved pretty quick. Before somebody launches a 3000 pound unguided missile at highway speed!
