I had almost forgot about the mature buck that turned inside out on me when I drew on him shooting PSE Dominators, the older style ones before the X weaves came out. And THAT was using teflon fork tamers.
I've since been told that you can quiet those down using hard paste auto wax, but I'd be leery of it leaving an odor.
I also had a treestand seat completely rip out from under me. It was really passed it's prime and I wouldn't call it a manufacturing flaw really. The biggest problem with that seat, was the weight of mine!
