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.

Telematics module failed and the vehicle couldn’t connect to emergency OnStar services if involved in crash. GPS also doesn’t work with a faulty module. No cellular or WiFi connectivity. Car reroutes to somewhere without this module working. I’m paying for the OnStar subscription but with a faulty module it can’t connect. GM says part back ordered with no ETA. Thousands of people are reporting the same problem and it should be a recall at this point.
