2023 CADILLAC LYRIQ Exterior Lighting Problems

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.

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.

Headlights droop over time driven which can severely limit forward vision. The limited vision forward at highway speeds certainly reduces safety. This is an intermittent problem that I can find no real pattern except that the longer you drive at night, the more likely the problem will surface. The problem has been confirmed and headlights replaced by at least three dealerships I first noticed the problem about 6 weeks after purchase because we do not drive much at night. [XXX] Also of interest is a surprising number of headlight assemblies for the Cadillac Lyriq are for sale on Ebay even though only a few thousand cars have been delivered.

Manufacturer has replaced and recalibrated headlights on 2 occasions however they will not maintain aim on road. This is consistent and as of now besides the repairs performed they do not know how to rectify this. Additionally in the rain or moving from a shadow to sunlight the rear cross traffic alert will trigger if enabled on vehicle causing emergency braking for no reason. it will continue to happen until turned off and car restarted. The car has been towed on 3 occasions in the first 4000 miles for complete loss of power. Dealer solution to remove 12v battery and reinstall same battery to clear elcectrical codes however problem keeps occurring.

Low beam headlights have very poor throw which degrades while driving. After driving the vehicle for 30 minutes, both left and right headlights point downward and do not throw light down the road. Cutoff is steep, with light only going about one car length. The fault is variable and somewhat random, with sometimes just one headlight drooping. The car must be driven for this to happen - does not occur when sitting flat or idle. The amount of droop varies also (confirmed by placing various pieces of tape on garage wall, and checking headlight position before and after a trip). Although the magnitude of droop is variable, nearly any trip will cause at least some amount of misalignment. When the fault is severe, even the high beams do not function well - just illuminating a very bright spot directly in front of the vehicle - and not down the road. Vehicle has electronic motorized leveling system for the headlights. The headlights go through some sort of automatic adjustment process when the vehicle is turned on. When the fault has occurred, turning the vehicle off and then on temporarily corrects the issue. Of course, this is not possible to do while driving. Driving at night in this vehicle is hazardous with this behavior. Numerous other Debut Edition and 2023 model year owners are experiencing this issue - not an isolated occurrence.

The aim of the headlight beams droops over time to dangerous low level where the headlings barely light beyond 30 feet. The highlights would re-level and re-adjust the aim at restart, but they would start drooping to dangerous low level within 10 mins of driving.

When the vehicle first starts, the headlights go through some sort of leveling routine and the light spread seems to illuminate a reasonable distance ahead of the vehicle. However, over as short as a few minutes of driving, the headlight seems to droop significantly and can result in only a very short section of road being illuminated ahead of the vehicle. This makes it very dangerous to drive at night as not enough of the road is illuminated ahead of the vehicle. The headlight throw pattern is not always uniform and there may appear to be something like a notch in the light pattern. This does not seem related to adaptive forward lighting as I do not see an active change in the light pattern based on driving.

Low beam headlights work appropriately for 5 or so minutes before "drooping" or "sagging" so that they only illuminate one car length or so in front of the vehicle. Upon shutting off and restarting the vehicle, the lights return to correct illumination. However, they somehow droop again and within 5-10 minutes, it is not safe to drive the vehicle on low-beam headlights. It is the equivalent of having only fog lights on.
