Yeah there could be some interesting things come from that.
I know all the sets I have seen out there have been fine, no issues in Classics or AF1 versions, including the half a dozen sets I have had on boards, but they don't get much action really. Other people have ridden them stock and with swapped out bushings, including stock Indy bushings, which worked well in the few sets I skated with them.
When I see or hear things from people on this thread, I definitely wonder what caused it or if things could have been better for whoever is on them if they had a little experience or knowledge, but given I don't know or hear the whole story, I couldn't say either way. There have definitely been a lot of warranty claims.
Then there are other simple things that don't need any warranty, for example, this pic of instantly blowing out bushings from a guy tightening them down way too much way too soon. Turns out they worked fine when loosened off and he just got used to them. This is only one version of these sort of things though. (Yes taken from a google pic - not my own.)
