The one that came with the system has a left stick that is now too sensitive, and your character will walk to the left on their own.
The first controller I bought now has the same problem with the right stick. Camera moves on its own.
The third controller, this one is only a few months old, has a R2 button that is too sensitive. On a pinball machine, for instance, the right flipper will constantly flip really fast. This was probably because I played Ratchet and Clank with the trigger resistance on (because the gameplay kinda involves it), and that shit will break your shoulder buttons. You can feel it happening as it jumps around.
I'm not a dumb player that abuses his controllers and pushes too hard. I've been gaming since the NES, and the only controller I've had problems with was of course the N64, because those were built to fail. But beyond that, never had controller problems. Through all the Playstations. They always worked for as long as I owned them. Hell, even my Switch joycons are fine, there is no stick drift with them.
The PS5 controllers may have a lot of bells and whistles, but they are the shoddiest controllers I've ever had, sans the N64 joystick. These things just break down.
