MALFUNCTION: In normal driving mode the stop lamp / brake lights do not shut off after releasing the braking controls. The stop lamps will shut off only after the accelerator pedal is used, or when the vehicle coasts below 10mph. SAFETY: 1) When descending mountain roads the stop lamps remain illuminated for extended periods of time. In some cases the stop lamps remain illuminated for hundreds or thousands of feet after the brake controls have been released. In these situations the vehicle is now coasting downhill and NOT decelerating. In these situations there is no indication / communication provided to the traffic behind me that I am now braking and no longer coasting since the stop…

My Cadillac Lyriq 1GYXPZRL1TZ601181 Has dents on the passenger roof rail. There are three dents one above the front door and 2 on the rear door. I discovered the dents on May 17, 2026 and I showed my local dealer on May 18, 2026. I have not been in a hail storm. My dealer said I need to file an insurance claim. Upon further research I have discovered that other owners have reported the same mysterious roof rail dents.

Driver Side Headlight erratic flicker while parked. Low beam unexpectedly turns on and turns off. Causes eyeball light sensitivity upon approach and could cause epileptic seizures for some. Problem has been replicated by dealer with video evidence provided by me. First attempt to fix was to provide software updates. That did not remedy. The second attempt was a full and complete inspection of all wires and modules which were in tact followed by a full replacement of the headlight assembly. This also did not remedy. The third attempt did not perform any action and to mark the concern as "operating as intended." No warning lamps or other indications except being in front of the vehicle while…
Sep 6, 2025Forward collision avoidance › Adaptive cruise control
Adaptive Cruise Control (ACC) caused dangerous unintended acceleration. This model of vehicle has an ACC that maintains following distance from a leading vehicle. It will decelerate to a full stop and will resume after a full stop while maintaining a proper following distance when prompted by a brief push on the accelerator. At the beginning of this incident, my ACC was set to about 40 MPH and I was following the car in front of me. At a traffic light, I came to a full stop behind the leading car for 10-15 seconds. At this point, I realized that the left lane turn signal changed to green which would allow me to proceed. Since there was no traffic in that lane, I decided to move from my lane…

Within a few seconds, various warning lights appeared on the dashboard, including messages such as "One-Pedal Driving Unavailable," "Brake Assist Off," "Auto-Hold Unavailable," and "Steering Assist is Reduced - Drive with Care." Additionally, warnings for "Service Headlamps," as well as red or yellow indicators for…
