Hazard Flashing Warning Light Unit problems of the 2017 Chevrolet Malibu

Going to work on a city street car completely shut off. It blacked out. No hazards no lights and this was at 3:30 in the morning. And it's happening more and more. It happened to my husband on a busy street. All we can do is wait and try to start it until luckily it did. But before this started, the car kept on shutting off on me when I come to a stop. It's happened at least 6 times in the last 3 weeks. And today it stated on the dashboard that it was reducing its speed. What's next?! it's dangerous because I have my kids with me and I'm afraid someone might rear end me one day. Or if it completely blacks out on me on my way to work and I have no one to help me and I get stranded. I wish they would do a recall. I've seen online how it's been happening to a lot of people.

On 03/10/21, I was driving north on a busy highway. I approached the stop light and reduced speed. I came to a full stop and the car shut off completely. The check engine light came on briefly, then lost all electrical power. I had no hazard lights, no radio, no dashboard, nothing. After being stranded for 5 min like that at a very dangerous left lane stop, the car finally restarted. Called onstar immediately to scan the car for codes - they found none. The issue of the car intermittently shutting down like that has happened multiple times since October of 2020. Taken the car to Chevrolet dealership multiple times and was told they cannot find anything wrong. I currently have it at the dealership and am being told they can find nothing wrong despite four different people in my car witnessing it happen to me more than once and my providing a log of every time it's happened.
