No. The problems I've experienced are with another brand. It has happened more than once and with more that one model.
I'm not saying that 7000 is always the best choice. 6061 can work and we haven't touched on hardening. What I can say is that the problems I've experienced have all been with 6000 series alloy, when materials related, with flange placement, when design related or tolerance related, when dealing with worn tooling.
