2025 Cadillac Lyriq problems

Filed Oct 2, 2026 · Brakes, Driver assistance · NY

My 2025 Cadillac LYRIQ has approximately 12,000 miles. On multiple occasions, the vehicle has unexpectedly applied the brakes and come to a sudden, forceful stop even though there was no visible vehicle, pedestrian, or obstacle requiring emergency braking. During the most recent incident, the abrupt stop caused my body to move forcefully and I developed neck pain. This creates a serious risk of injury, loss of control, or being struck from behind. The vehicle has also displayed “AWD Temporarily Unavailable,” ABS/brake warnings, vibration while braking, steering vibration, and shaking during acceleration. These symptoms began before the latest sudden-braking incident and have continued after a previous software update. I attempted to obtain diagnosis and repair through Pepe Cadillac and North Bay Cadillac. I was told at different times that the vehicle could not be serviced promptly, that there was no technician or loaner available, or that the vehicle did not have applicable warranty coverage because it was previously a fleet vehicle or was not purchased from that Cadillac dealership. GM/Cadillac Customer Care has also been contacted repeatedly, but the safety problem remains unresolved and no complete diagnosis or permanent repair has been provided. The vehicle remains available for inspection. I request that the federal safety agency associate this complaint with Engineering Analysis EA26006 concerning the Gen 2 eBoost system/Electronic Brake Control Module and review the vehicle’s event data, stored diagnostic codes, service history, braking system, Automatic Emergency Braking system, ABS, AWD system, and EBCM.

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 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.

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.
