Steam Controller Left Stick Issues?

Hello,

Has anyone had issues with what seems to be the left stick of the latest Steam Controller? Specifically I’ll notice my character in game (Diablo 2 R) will take off in a direction randomly. Or while playing a FPS game sometimes my character will forcefully strafe in one direction.

Is this software or potentially a hardware issue? I’ve had it since May, and baby it. So not drops and fairly light usage.

Thanks.
