2024 CADILLAC LYRIQ Complaints

While driving at night, my headlights will randomly aim down. Can’t see the road ahead. When high beams are activated, they blast the front of the car. Cannot see anything down the road.

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.

Unable to see behind the vehicle in the dark. There is no backup camera image at night, screen remains black.

Within two month the Lithium ion battery failed twice. and the car was not derivable. It had to bet towed to the dealer.

Backup camera is black with lines when shifting in reverse. Unable to see to backup and almost hit someone walking behind me

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.

The car has 7300 Miles on it and it has an electrical Battery error that it can not start Also multiple soft ware errors the screen turns off while driving and assist control errors

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.

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.

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.
