2023 CADILLAC Lyriq

The gauge cluster/infotainment screen dims automatically when the light sensor on the dash senses the environment has gotten darker. The problem is that this happens extremely early at dusk/dark hours when it's still fairly bright outside, and the brightness of the screen is too dim to see things clearly. Also, once this automatic dimming happens, there is no way to turn the brightness back up. This feature also CANNOT be disabled in the settings anywhere. This results in a safety issue where the screen is not sufficiently visible at times when the auto dimming (which is also tied to the automatic headlights) kicks in for the screen.

During dusk and dawn conditions, the vehicle dims the dashboard lighting to the point that everything is very difficult to see. They are diming the displays when the exterior lighting conditions are still too bright for the very dim display. I have owned many GM vehicles with this type of automatic diming and this is the ONLY vehicle that has this problem. There is NO user fix available. This is a safety problem and GM needs to be forced to provide a fix. Many owners complain about this problem and there is no fix available from dealers.

The entire left portion of the screen became inoperable and remained a black screen despite attempts to reset the system. The left side of the screen contains information such as gear selection, speedometer, lane keep assist, and many other important information. There is no other way to see what speed you are going besides this screen. Several others in my cadillac lyriq facebook group have experienced this issue, it is a major safety concern and needs to be addressed immediately before someone gets hurt from this.

Weather was dry. Time was 5:30 PM - still sunlit. Driving down the interstate, 70 MPH in the middle lane of a three lane highway. Super Cruise is active, no cars in front of me within 500+ feet. I MAY recall a partially blown tire in the lane to my left. All of a sudden, car brakes and slows abruptly to about to about 40MPH. I can not recall of brakes were active but my car was configured for "one pedal driving" so when the accelerator was disengaged, the brake is applied. "Service Driver Assist" warning comes on. The service driver assist icon on the dashboard remained yellow. The next morning, the service driver assist icon was gone.

Vehicle is automatically braking at low speeds when there is no reason to do so. It is as if the vehicle thinks something is there but there is nothing there

While transitioning to day to night, the instrument panel dims prematurely making the content very hard to see. This includes all indicators such as speed, turn signals, and other gauges and possible fault indications. This happens prior to dusk, when there is still plenty of daylight remaining. The headlights come on (this is fine), but the display dims to full night mode at the same time also. Although the instrument display night illumination level is adjustable with the dimmer switch, even at maximum setting the instrument panel cannot be well seen. Once the sun fully sets, the display visibility for night viewing is fine. The same issue occurs at the night to day transition. The display stays dim much too long into dawn, again presenting visibility issue of the controls and gauges during this time. This problem is not isolated to just my particular vehicle. When the vehicle was in the shop for various repairs, loaner Lyriq's provided exhibit the same issue. Both 2023 and 2024 model year, over various trims.

The Lyriq, as well as all current GM vehicles, use an icon on their instrument panel for indicating headlights are on that is incorrect. They use the symbol for parking lights rather than the symbol for low beam headlights on their instrument panel display. This is especially confusing because their own digital menu to turn on lights correctly shows the low beam headlights symbol for headlights, and the parking lights symbol for parking lights. However, turning on low beam headlights shows a parking lights indicator in the dashboard, and turning on the parking lights shows no indicator in the dashboard. It's my belief that, to help ensure no driver misunderstands what the symbols are indicating, that GM should have all vehicles properly use the low beam symbol for a dashboard indicator to show headlights, just like other vehicles use, rather than the parking lights indicator which is incorrect (both inconsistent with US convention, (as well as inconsistent with their own menu in the Lyriq specifically) to turn these lights on.

The 2023 Lyriq has 3 selections on the touch screen menu for the level of regenerative braking. They are: 1. Off 2. Low 3. High (I did not go out to my car to see exact wording) The serious issue is that, without notice to the driver, the setting can be reset to "Off". This must be a programming error or bug, but what is dangerous is expecting regenerative braking and NOTHING happens. You are forced to reset the level of regenerative braking. At a random interval, the setting will again RESET. This should get IMMEDIATE attention at GM's Lyriq design center.
