Backing out of driveway and screen went black and a collision occurred a second or two later. We have had the Lyriq in the shop multiple times for glitchy screens and screen going black but never has been fully resolved. I did recieve a recall letter (unfortunately I threw it away) but now it shows no recalls (strange). This black screen issue has been a problem since day 1 but now it has resulted in a collision. I have been unable to even back my car out of the garage when raining due to the sensitivity of the collision detect so there is NO excuse that it didn't alert. Cadillac has had the car since the accident and claim nothing is wrong with it and they are not responsible. I do not believe that. I have met with dealership GM who is looking into this further. I wanted to bring to the NTSB as this is 100% a safety concern. Thank God there wasn't a child on a bike or a baby in a stroller behind us. This didn't result in any human harm but the vehicle sustained damage that I believe was the direct result of malfunctioning technology on the car to prevent it.

The gauge cluster/infotainment screen dims automatically when the light sensor on the dash senses the environment has gotten darker. The problem is that this happens extremely early at dusk/dark hours when it's still fairly bright outside, and the brightness of the screen is too dim to see things clearly. Also, once this automatic dimming happens, there is no way to turn the brightness back up. This feature also CANNOT be disabled in the settings anywhere. This results in a safety issue where the screen is not sufficiently visible at times when the auto dimming (which is also tied to the automatic headlights) kicks in for the screen.

The entire left portion of the screen became inoperable and remained a black screen despite attempts to reset the system. The left side of the screen contains information such as gear selection, speedometer, lane keep assist, and many other important information. There is no other way to see what speed you are going besides this screen. Several others in my cadillac lyriq facebook group have experienced this issue, it is a major safety concern and needs to be addressed immediately before someone gets hurt from this.

Weather was dry. Time was 5:30 PM - still sunlit. Driving down the interstate, 70 MPH in the middle lane of a three lane highway. Super Cruise is active, no cars in front of me within 500+ feet. I MAY recall a partially blown tire in the lane to my left. All of a sudden, car brakes and slows abruptly to about to about 40MPH. I can not recall of brakes were active but my car was configured for "one pedal driving" so when the accelerator was disengaged, the brake is applied. "Service Driver Assist" warning comes on. The service driver assist icon on the dashboard remained yellow. The next morning, the service driver assist icon was gone.

Vehicle is automatically braking at low speeds when there is no reason to do so. It is as if the vehicle thinks something is there but there is nothing there
