EXTERIOR LIGHTING
The auto leveling lights drift during driving. On staff up, the headlights will point up and down, then self level. However, for the past week, the right headlight drifts down towards the road and the left headlight will drift upwards after about 20-30 minutes of driving. The downward drifting headlight only illuminates about 1 car length ahead while the upward drifting headlight will point towards overhead street signs. This causes reduced visibility with increased flare and reduced headlight throw at the same time. It also is dangerous to incoming traffic since the left headlight ends up drifting upward to produce a throw similar to a high beam, even though the high beams are off. The only way to get the lights to re-level is to shut off the vehicle and restart. Even after this, the lights will only be at the correct level for about 20-30 minutes as they start to drift in opposite vertical directions while driving. There have been multiple reports of similar cases on forums discussing the Cadillac Lyriq. Since the problem only occurs noticeably after 20-30 of night driving, the dealer has stated they can not reproduce it while in their possession. There are no warning messages or codes displayed.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, ELECTRICAL SYSTEM
While driving the 12V battery system failed as well as the high voltage charging system. The vehicle lost traction control in the rain and was slipping on the road. The forward collision detection also intermittently goes out. If you are in one pedal driving mode and using adaptive cruise control when the forward collision detection goes out it will deactivate adaptive cruise control and apply enough regenerative breaking to rapidly slow the car. If the driver does not have their foot on the accelerator when this happens and you are in traffic it could cause an accident. The vehicle is not saving any diagnostic information regarding these failures and dealerships will not work the failures without diagnostic codes.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
After dark, the rear camera is inactive. Also after dark, sometimes the backup lights do not come on in reverse. According to [XXX] , this is due to a defect with the rear electrical harness because an active license plate light circuit interferes with the camera and backup lights circuits.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: WARNINGS
What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components of our driver assistance software have failed, beyond what we can check in the fields above. Most recently, we have experienced two major failures. The first failure occurred when the car triggered the emergency parking brake on its own while we were driving in traffic at 30 mph. We narrowly avoided being rear ended. This is the incident I've detailed in the fields below. The second failure occurred when the adaptive cruise control failed to brake as we approached gridlock traffic. We again narrowly avoided collision on multiple fronts. We were going approximately 45 mph with roughly 2000 miles on the car. We have the service records, but the selling dealer and Cadillac engineering claim these issues are now fixed. How was your safety or the safety of others put at risk? We were well within less than a car length of collision in both of the situations described above. This car is a large SUV, it would presumably cause significant damage to cars it hit. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. They verified failures and out-of-date software in our vehicle in this last service visit. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This vehicle has been directly inspected by Cadillac engineering through our selling dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The warning lights we experienced included the warnings that the system had engaged and "service driver assist system." There was no warning when the adaptive cruise control failed.

EXTERIOR LIGHTING
The headlamps in the Cadillac Lyriq are supposed to be self leveling, maintaining a consistent throw throughout a drive. My left headlamp droops significantly after 10-15 minutes of driving, failing to throw its beam more than 15 feet ahead. This poses a a safety risk because it decreases my ability to see pedestrians or road hazards. This has not been reviewed by a Cadillac dealer yet because it is a known issue to which GM had no current solution. There are no warning signals that appears in the car’s screen. The two pictures below show the headlamps at start up and after 15 minutes of driving. The droop in the left lamp is noticeable. The pictures were taken from the same spot and at the same angle.

Same stop sign as yesterday but today it vibrates warnings Makes not sense.

EXTERIOR LIGHTING
Headlights start dropping as car is driven. Every 10 to 15 miles must pull car over and restart as you can not see further than a car’s length in front of you. Cycle car off and then back on the headlights return to normal for another 10 miles. Also seems that some of the individual lamps start pointing upward blinding oncoming drives even with most of the lamps are pointing down in front of the less than a cars length. Seems the headlights are making adjustments be are not correct until you do a power cycle.

EXTERIOR LIGHTING
Headlights on vehicle “droop” after driving 20 minutes or more. They start off okay and then become non existent l, pointing directly down toward the pavement in front of the vehicle and you can’t see more than 1 car length in front of you. You must turn the vehicle off and then back on to reset the headlights to drive. This is a huge safety issue for driving at night.
