2025 Cadillac Lyriq Problems

Stopped at the West Bound Thruway Seneca service area. After returning to the vehicle, multiple error messages were displayed on screen. "Have Power Steering Serviced, Service Stabilitrak, Service Headlamps, AWD Tempoarily Unavailable" Steering was the main issue. It was almost impossible to turn and steer. It was fortunate that it was after a stop and not while driving. The vehicle was towed to the dealer but it has yet to be determined why the steering failed.

OnStar system on the vehicle is busted. Because of this the accident detection no longer works and the GPS is stuck in no mans land which makes it impossible to use their app to figure out charging percentage, how far and route to take to the nearest charging station.

I did some online research and am concerned that the accident may have been caused by a safety issue reported on our 2025 model Cadillac Lyriq involving its One Pedal Driving (OPD) feature. We had tried using OPD when we first got the car and didn't like it and have not engaged it again over the past year. However, after an Over The Air update last week, the feature seems have been engaged by itself. I noticed it the evening before and needed to research how to disengage. In the mean time my wife had to go out before I was able to disengage it, and not realizing the issue was anything but undesirable she went out to an appointment and had an accident pulling into a parking spot at Walgreens. The car surged forward into some small bushes and a small causing damage to the front bumper, grill cover, and several other pieces. No one was hurt, but the risk is obvious.

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 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.

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.

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.

Sudden Acceleration. -I was driving on a highway. I accelerated to pass a truck and when I took my foot off the accelerator the car continued to gain acceleration. The gas pedal had returned to a normal position but the car was still accelerating. I had to put full force on the brakes to get the car to stop. One of my passengers noted that there were flames around one of the brakes. I turned the car off and we waited approximately 45 minutes for the brakes to cool enough to proceed without further incident.

I was in a public parking lot and slowly approached a parking space in front of a store. When I applied the brakes to stop in the space, the car did not respond, it continued to drive forward, up the curb, crashed through the store front, and eventually came to rest mid-way in the store, amidst the furniture and store structure.

The contact stated that while driving 5 MPH during dry weather conditions in traffic, the brake pedal was depressed but traveled down to the floorboard, and the vehicle failed to respond. The contact stood on the brake pedal; however, the vehicle failed to respond and crashed into the vehicle in front that had stopped due to traffic. In addition, the contact stated that the brake pedal jerked while it was depressed. No warning lights were illuminated, and the Crash Imminent Braking system failed. The driver-side and passenger-side air bags did not deploy. The contact suffered injuries to the back that did/did not require medical attention. No police report was filed. The contact drove the vehicle to the residence. The insurance company was not notified. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 10,000.

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!
