NHTSA Complaint #11480237 — 2014 JEEP CHEROKEE

My 2014 Jeep has been experiencing intermittent shut downs, the dash goes dead at random times for a few seconds and then comes back on the issue continues. This issue started in December 2021 during that time I was driving at night and the dash, exterior lights and interior lights started flickering. Now this issue occurs 90% of the time when I drive, sometimes when the dash goes off different warning lights come on, TCS, SRS, Power steering and if the vehicle is traveling below 5mph it sometimes dies completely. Battery was replaced 1 year ago. The middle screen on the dash gets super dim and it appears to still be on if you look closely at night but the dials are frozen at the current speed and rpm. My mechanic tested the battery connection and there is nothing loose that would cause this.
