NHTSA Complaint #11657397 — 2025 CADILLAC LYRIQ

The infotainment screen automatically adjusts its brightness based on readings from the ambient light sensor. However, during dusk and dawn, while conditions still appear relatively bright to the human eye, the sensor interprets the light levels as low and significantly dims the screen. As a result, the display can become so dark that it is nearly unreadable. This issue occurs even when the brightness control wheel is set to its maximum setting. The light sensor overrides the manual brightness adjustment, and the control wheel can only further reduce the brightness, not increase it. GM should provide an option to disable automatic brightness adjustment, or update the auto-brightness algorithm to prevent the screen from dimming excessively under such conditions.
