Joystick direction has been sticking randomly on 3 different Tartarus V2's

SO first off I am on my third Tartarus in about a year since twice the joystick in one direction had turned to mush and wouldn't register, and I really didn't have a ton of playtime on either one. Across all three though, I randomly experience movement being locked in place in game for a random length of time. I'm not sure if it's an issue with the joystick again itself or with the software locking up in a sense. But anyway, it's ridiculous when you're playing competitive Overwatch and your movement gets stuck in one direction and all you can do at the most is hold the opposite direction to lock yourself in place.
