Cadillac Lyriq Reliability by YearBest & worst years, problems & recalls — NHTSA data

Car has been asleep after parking and will not wake up leaving all electrical components dead. GM has not been able to repair and unfortunately this has occurred 5 times including twice the month of March, 2026. Having a car parked in an unsafe location and not being able to move it very unsettling. After 30-60 minutes the car will start back up and operate normally.

The contact owns a 2025 Cadillac Lyriq. The contact stated that after starting the vehicle, there was a cracking sound inside the vehicle. The contact looked up and saw that the moon roof glass was cracking. The contact stated that the crack had extended several feet. There was no impact on the moon roof glass to cause the glass to crack. The local dealer and manufacturer were notified of the failure, but no assistance was provided. The failure mileage was 6,000.

My car is equipped with a forward-facing camera, mounted on the forward area of the interior rearview mirror. Additional cameras are mounted on the front bumper, trunk door, and on the rearview mirrors on each side of the car. Various sensors mounted throughout both bumpers face the front, rear, and each side of the car. At the time of this incident all sensors and cameras were clean and free of obstructions, and software was up to date. I was driving uphill, negotiating a tight left curve at approximately 30 MPH in a rural, forested area in the Santa Cruz Mountains (California.) There were no other conveyances, objects, or obstruction on the roadway in front or behind me. The weather was clear and the daytime visibility was excellent. The road was dry and I estimate its gradient at 30%. As I was about to enter the curve, the vertical dirt hillside appeared ahead and directly in front of the forward-facing cameras and sensors, which I supose, detected this topography. With minimal pressure, I had my right foot on the throttle to keep the aforementioned speed while turning. The cruise control was not in use. As I began to turn, and while still facing the hillside, the throttle stopped responding and the car decelerated. Simultaneously, a warning appeared on my dashboard screen, indicating the forward collision warning system was unavailable. I fully depressed the throtle but instead of gaining speed, the car slowed down to 12 MPH as I completed the turn. In quick succession, I lifted my right foot of the throtle and depressed it all the way to the floorboard but the car did not accelerate. The car eventually regained forward acceleration when I had the throttle pedal all the way against the floorboard but despite this severe throttle application, the car only accelerated very slowly. Thereafter, the throtle resumed normal operation and I continued my trip over the hills and back. I believe I could have been rear ended during this scary incident.

Telematics module failed and the vehicle couldn’t connect to emergency OnStar services if involved in crash. GPS also doesn’t work with a faulty module. No cellular or WiFi connectivity. Car reroutes to somewhere without this module working. I’m paying for the OnStar subscription but with a faulty module it can’t connect. GM says part back ordered with no ETA. Thousands of people are reporting the same problem and it should be a recall at this point.

Bad Telematics Unit thats backorderd forever.

I was driving about 40 MPH, message popped "camera blocked, clean front windshield" I did and the message cleared. A few minutes later it came back so I cleaned the windshield again. What happened next shocked me. Without any warning while traveling 30 mph the automatic braking system came on and stopped the car quickly. Thank God for my seatbelt! My backpack that was in the back seat came flying to the front. No warning at all! I called the dealer and brought the car t them. They told me they need to load new software in the car that would take 5-6 hrs. They did the software and told me that it should be all set now. I picked up the car and drove it home. A few days later an incident more alarming happened! I was at a traffic light, car stopped and auto hold when suddenly the car accelerated on its own. I pumped the break several times and the car eventually stopped. I was terrified. I called the dealer and brought the car there the next morning. Dropped it of Saturday morning. I call Monday afternoon and spoke with the service person and he told me they could not replicate what happened and that there were no bulletins from Cadillac. I asked how they tested it and he told me they took it for a ride and also looked for any errors recorded in the cars memory. I said it happened to me once in 2 days so taking it for a short ride will not necessarily repeat what happened. He said they will hold the car and look at a few more things today. I just spoke to the dealer and they told me they drove the car for 15 minutes and found no issues. They also said they are looking for any bulletins on the car. Not sure what the outcome will be but these 2 incidents could have both been very ugly and people could have gotten very hurt. I ask myself...should I be driving this car!

I purchased the 2025 Lyriq new on May 11, 2025. On May 30th with 5400 miles on the car, the front right wheel tie rod snapped off while driving causing the wheel to turn sideways. I was making a turn on a secondary sheet when it happened and was able to pull to the side of the road. Had I been driving on the highway at the time, I could have been killed or hurt another driver. I had the car towed to MacMulkin Cadillac on June 1. The dealership noted that it was bad welding and the car showed rust and rot in that area. It will be 30 days this Monday and no one from GM has been out to investigate.

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.

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.

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.
