Cadillac LYRIQ

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…

On or about August 6, 2026, I received email communication from the GM EV Concierge , establishing Case #106606137. My vehicle has been bricked and GM has had possession of it since August 3, 2026, (46 days and counting) without so much as an official diagnosis or repair timeline. I have repeatedly been told that the matter has been “escalated,” that GM is “working with the dealership,” and that the repair is being “expedited,” however, I don't know to whom it has been escalated, but at this…

The vehicle is a Cadillac Lyriq. Following an over the air software update pushed by the manufacturer, the vehicle began displaying a high voltage system error message and lost the ability to DC fast charge. The high voltage components themselves are reported to be functional, the issue appears to be caused entirely by the software update rather than a hardware failure. The vehicle has been at an authorized dealership service center since August 14, 2026, awaiting a resolution. The dealership…

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 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.

On August 9, 2026, at approximately 3:40 a.m., while driving, the vehicle suddenly lost all propulsion and became completely disabled on the roadway. The vehicle remained powered on but would not move forward or backward. At approximately the time of the failure, Cadillac/OnStar Advanced Diagnostics generated a critical Electric Drive Unit warning instructing immediate service and reported diagnostic code P0A78. Additional vehicle diagnostic warnings involved the electric drive…

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.

The infotainment screen in my car plus the menu control went completely dead. With the screen dead completely this mean you cannot see the speedomoter, rear camera feeds, warning symbols on the dash. You cannot see current speed, you cannot hear any sound so all alerting systems are down. You are completely blind in a vehicle built around this screen. Dealership has already confirmed faulty computer module. However was told it would have been originally resolved under N252500680. It has only…

This is about an issue with the ACC system. While driving with the ACC engaged, it will intermittently disengage and without notification. Then the vehicle applies hard braking. After many multiple occurrences, I now tap the brake pedal and apply acceleration. I can't tell you how concerning this can be while driving at interstate speed. Just the thought of a large truck behind me will put the fear into you. Additionally, I have been able to hear an electrical clicking noise emitting from the…

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…
