NHTSA Complaint #11660666 — 2024 CADILLAC LYRIQ

The main driving display in my 2024 Cadillac Lyriq has faulty software or light sensor calibration - the vehicle automatically dims the screen (including the speedometer) to unreadably low levels, is extremely slow to respond to changing lighting conditions and time of day (the display changes between day and night modes automatically but is constantly confused by lighting conditions). This happens most often at dawn and dusk. I will be driving in bright sunlight with the sun glaring in my eyes, and the screen will think it's night and be dimmed way down to about 20% brightness. Customers have no way of overriding this. There is no setting to disable automatic brightness, and some customers have taken the time to manually unplug the daylight sensor on the dash to resolve their issue. Additionally, the system is extremely sensitive to going under overpasses, which will immediately dim the entire system to about 20% brightness and stay that way for a long time after returning to bright sunlight. This also happens when pulling into my garage, where the display dims down so low that I am unable to see the safety cameras around the vehicle in order to park my vehicle correctly. GM has been made aware of this issue, and they've been aware of it for years. I've spoken to GM directly, and they say, "a fix is coming," but it's been years and nothing has been done. They've issued multiple software updates, none of which address the problem so far. Subsequently released vehicles, like the Optiq, have this issue resolved. GM knows how to fix it, and that's an issue; they just do nothing about it. This is a very well-known, very widespread issue for other Lyriq owners. You can find chat chains on Reddit discussing this issue, and even one where multiple owners talk about starting a class action case on it as it involves vehicle safety. I'm attaching photos of what my display looks like when the sun is out in the morning. It displays the same behavior at dusk.
