It doesn’t seem like this should be a product specific, or even a brand specific problem. I experienced this only twice in the past four years. Once on a Campy 8sp drivetrain, and once on a SRAM Red setup. In both cases I concluded the cause to be cable stretch a few weeks after installation leading to the index position drifting off center and mysterious shifting at random times. Sometimes I didn’t even have to hit a bump!
In both cases checking and centering the indexing solved the problem. Cleaning the chain and gunk between cogs helps too.
