Not normal. This sounds like the upper intermediate steering shaft problem. I had mine replaced in late 2021 and it is loose/clunky again. Going to take it back to the dealer to have it replaced again soon.

My infotainment screen dims with the instrument panel lights, but adjustments only work at night (or when I cover the light sensor on the dash). Attached picture is from the manual that describes the feature only being functional at night.
