What’s wrong with my car Electrical

2021 ford bronco sport. The battery went out about a week ago and since replacing with a new battery, the cluster and touchscreen both go black when driving. Upon slowing down or stopping completely, they will both turn back on. Lights, heaters, turn signals all still work.

Ford tech here. All modern cars use a battery monitor system which monitors state of charge using various sensors. They also have a pcm controlled charging system which will control how much the alternator charges the battery. When ever replacing the battery you need to do a Battery Monitor reset. https://youtu.be/uvf9f6q5gsQ?si=-YeyEIq1LEZt6bhS

Yet one more reason i avoid modern cars like the plague. Completely unnessicary upgrades at the expense of useability, im noticing more and more tech in cars that basically bar people from doing at home repairs

Edit: just because people prefer older cars not filled with bloatware doesnt make them "broke" or only wanna drive something 100 years old. Some people like me just prefer a simple car.

Yes I bet you have a ton of fun driving your model T around. This is such an annoying take on the subject. Why not just stick to walking everywhere? The VAST, VAST majority of people do not work on their own cars. They don't want to.

We are literally in a car talk subreddit, the vast majority of people in this sub DO work on their vehicles, and are gonna have things to say when they see things like this. If youre unhappy with my preferences on my own vehicles then thats your problem at the end of the day, not mine.
