Cadillac Lyriq 2026: Retiros, Quejas y Ley de Limón de California

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.

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 to the open left lane. I turned the steering wheel to go around the car in front of me into the left lane. I then briefly touched the accelerator. The result was that the car accelerated at a high pace. Since my foot on the accelerator initiated the event, it took me a second or so to move my foot to the brake and disable ACC. During the acceleration, I was able to steer into the left lane and make the subsequent left turn without incident. I'm unlikely to make this mistake again. However, I'm pretty certain that this sequence is easily repeatable should you want to test for it. This ACC behavior seems dangerous. I expect that resuming ACC while following a vehicle will result in acceleration. But if the car is pointed in a new direction while it is stopped, it seems inappropriate to allow the ACC to resume by tapping the accelerator. A better ACC behavior would disable the"resume after a full stop" functionally if the wheel is turned more that a few degrees after an ACC controlled full stop.

**2026 - Cadillac Lyriq One-Pedal Driving and Brake Defect** On November 4, 2026, at approximately 9:30 AM, I was driving my 2026 Cadillac Lyriq using the one-pedal driving feature while going below 20 miles per hour. Suddenly, the vehicle accelerated unexpectedly. I lifted my foot off the accelerator, but the car did not slow down despite the one-pedal driving being enabled. 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 "Parking Setting," "ABS," and "Ready," were activated. I made several attempts to apply the brakes, but they did not respond. I even tried to engage the parking brake, which also failed. Fortunately, I was lucky enough not to hit anyone or run over any curbs during this incident. The 2026 Lyriq that I purchased has fewer than 500 miles on it and has been at the dealer service center for over two weeks. This is a significant safety concern, and I believe Cadillac should take immediate action to address this issue.

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 it occurs.
