Headlights problems of the 2015 Ford Fusion

I have made several complaints about my 2015 Ford Fusion. The air conditioner will randomly shut off, and when this happens, I also cannot use any of my 4 windows, the radio, lock the car from the inside, and now my outside lights wont always turn on. For whatever reason, this happens more in the summer months. I have two toddlers and we travel long distance fairly regularly. What happens if its a hot summer day, the ac shuts off and I cant roll down my windows, especially when I have my children? 6/19/2020 I had a doctors appointment one hour away and this happened to me; luckily I did not have my children with. I often work evenings and nights, half an hour away from home. I can't drive with no headlights. There is 0 pattern in these issues so I cannot pinpoint what exactly triggers this. Pulling over and completely shutting off the car, taking the keys out of the ignition, and waiting for all electricity to shut off before restarting the car does not make a difference. I had to bring my car in 3 times for this, each time being told "nothing found that was wrong with the car" until I called the Ford company, made a complaint, and received a case number, and am now being told the internal computer system is "shot". The more I researched online about these issues, the more I see other's making same/similar complaints for the same vehicle.
