ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM
We were exiting a parking garage when the car suddenly slammed the brakes on in the path of traffic and lost all electrical power. We could not get the car to turn back on or even get it in neutral to move it out of the path of traffic. Our [XXX] old got locked in the car because the car had zero electric power and someone helped us figure out how to unlock the car with the physical key. We were stuck for four hours because no one could figure out how to get the car out of the garage. If this had happened going at a high speed this could have caused a deadly crash, and it happened without any warning.

ELECTRICAL SYSTEM, VISIBILITY/WIPER
The infotainment screen automatically adjusts its brightness based on readings from the ambient light sensor. However, during dusk and dawn, while conditions still appear relatively bright to the human eye, the sensor interprets the light levels as low and significantly dims the screen. As a result, the display can become so dark that it is nearly unreadable. This issue occurs even when the brightness control wheel is set to its maximum setting. The light sensor overrides the manual brightness adjustment, and the control wheel can only further reduce the brightness, not increase it. GM should provide an option to disable automatic brightness adjustment, or update the auto-brightness algorithm to prevent the screen from dimming excessively under such conditions.

SERVICE BRAKES, STEERING, VEHICLE SPEED CONTROL
- Software failure resulted in loss of steering control, speed control, and brakes became unavailable. I was on highway car was at 65 mph and then I got a bunch of error messages mentioned below- 1) Steering assist not available 2) AWD is disabled 3) Headlamps not available 4)Service brake assist And then I was not able to brake the car, and steering became highly unresponsive. I took my foot of gas and let the car roll for 1 mile before stopping safely on shoulder, from where I called Cadillac for support (they towed the car back), since error didn't resolve after stopping or rebooting the car. I took screenshot of these errors after stopping and attached them in this email. - Yes it put safety of me, my passenger, and other vehicles at risk, loss speed and steering control you have cause me to hit any other car. - Yes problem is reported to manufacturer, car is in service. - Vehicle is with Service, since no one got hurt, we didn't involve police. - No prior message or warnings we recieved, all errors come as soon as the issues appear.

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS, SERVICE BRAKES, HYDRAULIC
The contact owns a 2024 Cadillac Lyriq. The contact stated that while driving under 35 MPH on several occasions, the brakes were independently activated. The TPMS warning light was illuminated intermittently. Additionally, the front passenger’s side tire was flat. The vehicle was taken to a dealer where it was diagnosed and determined that an undisclosed system software needed to be updated. The vehicle was repaired but the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 7,000.

Front doors have significant “bounce back” when you open them. You have to block the door from closing/slamming on your leg. The door has hit myself, my passengers and my grandchildren in the leg/shin.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
When it rains, just a steady rain, not a downpour, the vehicle slams on the brakes trying to back up. It literally took 3-4 minutes to back out of the driveway. I was also in a parking lot trying to back out and the same issue which created a significant safety hazard with other vehicles. Research online indicates this is not an isolated issue.

I am writing to report a series of alarming incidents involving my 2025 Cadillac, purchased on December 2, 2024. Within three months of ownership, I have experienced three separate occurrences that have caused me significant concern and physical distress. 1 Approximately two weeks after purchasing the vehicle, I was stopped at a red light. When the light turned green, I pressed the Pedal. Within three- 4 seconds, I felt a sudden impact from the rear, as if I had been rear-ended. However, upon inspection, there was no visible damage to my car, and the vehicle behind me was approximately 10 feet away. This incident was both confusing and distressing. 2 On a separate occasion, under similar circumstances, I was stationary at a red light. Upon the light turning green, I began to accelerate and once again experienced a sudden, forceful jolt from the rear. No vehicle was in close proximity behind me, yet the sensation was akin to a severe rear-end collision. The jolt was significant enough to cause me considerable alarm. 3 The most recent and concerning event occurred on the evening of February 24, 2025, around 8:00 PM. I was reversing out of a parking spot at a supermarket. Within seconds of shifting into reverse and beginning to back up, I felt an intense impact, as though a vehicle traveling at high speed had collided with the rear of my car. The force was so substantial that I was convinced a serious accident had occurred. However, upon exiting the vehicle, I found no other cars in the vicinity and no visible damage to my vehicle. Medical Following these incidents, I began experiencing severe neck pain. The discomfort persisted and intensified over the course of a week. On the morning of February 25, 2025, I sought medical attention due to the escalating pain. At the hospital, XR cervical spine was performed, and I have been advised to pursue follow-up consultations with specialists. There needs to be an investigation into these Occurrences.

EXTERIOR LIGHTING
The back up lights when in reverse at night are inadequate to safely back the vehicle up. This is true whether one is using the rear window and rearview mirrors or one is using the back up camera. No more than 10 feet of area behind the vehicle can be seen by using these lights.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On [XXX], my wife was driving our 2024 Cadillac Lyriq RWD (VIN: [XXX] ) in stop-and-go traffic on [XXX] at 5-10 MPH. She was maintaining a safe distance when the truck ahead suddenly stopped. She pressed the brakes firmly, but the vehicle failed to stop, resulting in a collision. Despite full brake application, the car did not stop as expected. The Automatic Emergency Braking (AEB) and Forward Collision Alert (FCA) systems did not activate. No alerts or braking assistance occurred, even though these safety features were enabled. Her passenger witnessed her screaming that the brakes were not stopping the car. The crash caused front bumper damage, and a police report was filed. Investigation & GM’s Response GM inspected the vehicle but refuses to provide testing details. The Crash Data Report does not show any recorded braking event or safety activation, despite my wife pressing the brakes. GM has not explained: Why the brakes failed to stop the vehicle. Why AEB and FCA did not activate. Why no braking data was recorded despite the collision. Safety Concerns My wife is now afraid to drive the vehicle and refuses to continue driving it after repairs. I may be forced to break my lease or sell the car due to this serious safety concern. This raises major safety risks for other Cadillac Lyriq owners, especially with known braking-related recalls on 2023 and 2024 models. Request for Investigation I urge NHTSA to: Investigate braking system failures in the 2024 Cadillac Lyriq. Review AEB and FCA non-activation during low-speed collisions. Determine whether GM is withholding data or failing to acknowledge a defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM
When driving, the infotainment screen glitched. This also affected the main instrument cluster containing information like speed, and inhibited any ability to control certain functions like the headlights. While the infotainment screen was scrambled, this was not a perceived safety issue [except that cameras could not be seen] However, the main instrument cluster was concerning. Correct speed, gear position, blinkers, etc were not shown or delayed. [e.g. when going approx 30 mph, the cluster stated approx 15 mph]

FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, UNKNOWN OR OTHER
I pulled my vehicle in my garage and was lightly tapping the accelerator to get the vehicle far enough in to avoid it interfering with the garage door. I had one-pedal driving engaged so I was not using my brake pedal. Once positioned I was getting ready to put it in park and the vehicle rapidly accelerated as if someone was stomping on the accelerator. It slammed into a refrigerator I have in the garage, pushing it about 2 inches into the wall, breaking through the drywall. The impact was so hard the refrigerator door also popped open and stuff went flying out. I had to slam on my brakes to get it to stop moving forward even though my foot was not on the accelerator.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When backing up my car from the driveway during rain it continuously applies phantom braking making it impossible to move the car. Turned off the rear autobraking but it still doesn’t help. It’s very dangerous. This is the same case for all the electric vehicles manufactured by GM and reddit posts exist for Equinox EV, Blazer EV, Honda Prologoue, Acura ZDX

The bigger issue is the car will prematurely dim the display and dusk/dawn - making it very hard to see at those times - even with max dimmer setting. Took it to the dealer multiple times they say it’s working as expected but it’s a known issue for all lyriq owners that GM ignores
