I just got mine, 2023 production model and don't have this issue. The panel illuminate beautifully during the day and it dims at night just like any other car I had, it dims, the cluster and center console dims as well and headlights goes on when set to Auto at night. I can also change the brightness of the cluster screen from the +/- buttons near cluster on the right as well as the Nav screen(there is day/night button to toggle and +/- shows on the screen after I press the day/night button). Also, I can press this button (day/night ) to switch to day mode which makes the nav screen and center console to full brightness without affecting the headlight or anything else. Try this day/night button at night while your lights are set to Auto and see how it goes. after you press it a +/- bas will show up on top of the screen for few seconds, you may quickly press + to increase brightness. My car doesn't have any flows but the rear climate control unit which doesn't seem to be consistent and blows cold air while its 39 F outside, loud fan on Auto since its not heating so the fan doesn't eventually settle to low speed! front works fine its just the rear.
