2025 CADILLAC LYRIQ Complaints

On XXX, I was involved in a collision with my 2025 Cadillac Lyriq with vin # [XXX]. in which my vehicle struck a parked car, then a tree, then a curb, in sequence, at approximately 30 mph. The vehicle continued onto the curb after the final impact. All passengers sustained injuries and required X-rays and medical treatment. There were no warning lights or dashboard indicators prior to the collision suggesting any system malfunction. During the collision, the front airbags did not deploy despite multiple significant impacts. Additionally, Automatic emergency braking didn't engage as it should Following the collision, inspection showed extensive front-end damage including damage to the tires, suspension, and cross member, hood, grill, fender etc. requiring full front-end replacement. I am requesting that NHTSA investigate the non-deployment of the airbag system and the brake failure in relation to this incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2025 Cadillac Lyriq. The contact stated that while driving approximately 45 MPH on a four-lane highway with the cruise control deactivated, the vehicle unintendedly accelerated. The contact stated that the vehicle accelerated above 100 MPH. During the failure, the cruise control erroneously activated but the speed was not displayed. The contact attempted to stop the vehicle by depressing the brake pedal but it accelerated instead. OnStar was contacted for assistance and moments later the vehicle decelerated and was driven to the shoulder. The contact stated that the vehicle travelled approximately 3 miles before the vehicle decelerated. The contact exited the vehicle, and there was smoke coming from the wheel wells and the brake pads. A tow truck was called to the scene, and the vehicle was towed to a local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 10,000.

I was driving on the freeway and was between two cars. The car on my right was trying to merge into me. I immediately was breaking while trying to control steering. I attempted to honk three times and my honk horn would not work. In a case of an emergency, that is absolutely unacceptable a car like this should be able to honk.

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.

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.

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.

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.
