Dangerous visibility hazard when backing up vehicle at night. Infotainment screen switches to "full brightness" when backup camera is activated, resulting in blinding light to driver. Driver can not backup safely without physically covering the screen to regain visibility. Screen brightness reflects off all 4 windows, windshield and back glass. Side mirrors are unusable in this condition. There was a fix for this issue on previous GM models, (prior to 2018), however no fix for 2019 - present

Brand new truck. Stuck at the gym in the middle of the night truck wont start. The interior lights, head lights, and radio wont shut off. Vehicle wont start. I'm assuming the battery was drained because interior lights, exterior lights, radio, wont shut off. Has to be some kind of electrical malfunction. Waiting on GM roadside.

When making right turns in the dark the headlights do not cast light to the right so you can see where you are turning. This is especially a problem in the rural without streetlights it is totally black from the drivers seat looking over the right side of the hood or out the right window.
