Radio/tape Cd Player problems of the 2017 Chevrolet Malibu

While parking, a "park to shift" warning comes on and will not turn off unless I jiggle the shifter or shift through several times. Lights and radio will not turn off until warning goes away.

When driving at auto stop, when beginning to accelerate, car acts like it shut off and says steering assist reduced drive with care. I noticed the battery voltage goes down to 11. 0 v. Also the radio screen flickers black. This has happened multiple times in multiple days.

Yesterday I was driving and pulled up to a red light. The car shut up as normal for the energy saver feature, but when the light turned green and I took my foot off the break and tried to accelerate the care would not move. The engine light came onto the screen. I waited 2 minutes, turned the car off and back on and it was fine after that. The radio's sound stopped working after that. Everything was normal on the display screen, but no sound was coming out, even when I pushed the on-star button. I pulled over and turned the car off for 10 minutes and back on and the radio worked again like normal.

While dropping off my children at school the car came to a complete stop and went into auto stop. When releasing the peddle so the car could turn back on the whole dash board and the radio screen completely cut off and when the car turned off it all switched back on. The dash screen flagged and said steering assistant is reduced drive with care. This repeatedly happended another two times everytime I came to a complete stop. After the third time the car did not turn off at all. In the past I have had the error message come on when the car would come to a stop and the car would turn back on but I am beginning to become very worried because now the whole dash board and radio are turning off. I was on a regular city street but am worried when I return to work after my vacation I will get stranded. I am attaching screenshots of a video I was able to capture on the third time this happened to me. The time is attached also.
