I have 2020 Dodge Charger with about 13,000 miles on it. I was pulling out of a store parking lot mind you cars was already running and driving. As I’m pulling out of the parking lot out to the main Road (It was dark out) I noticed my dash light up! when I looked down my gauges were moving and all lights on the dashboard were marking as if my car was just Being turn on! Music was still playing and I accelerated a little harder to see if maybe my car with failing or turning off. It wasn’t. I was startled for the rest of the way home about 15-20 mins away. Possible electrical problem.

 

I would verify that you have a good connection on both ends of the battery cable's. A bad ground will make your dash go crazy...

What Iowan said, or you could have blown a sensor. I had something like that happen to my Challenger a few years back.
Checking for engine codes might tell you what the deal is..

My suggestion is to take it back to the dealer. Should still be under warranty (3 years or 36,000 mile).. Check with them first....
If not? Then I agree with the others... Check the Battery Connections as well as testing the Alternator and Battery.
