NHTSA Complaint #11463171 — 2019 FORD F-150

My electrical system failed and then caught fire. The entire situation started 4 days ago where my "dome" or "cargo" light kept turning on even though the car was off. 3 days ago my alarm would go off every 15 minutes until I unplugged the battery. I disconnected the battery over night hoping to reset the computer. After reconnecting the battery I got a rear "LEFT REAR door ajar" message on the dash. After inspecting the sensor and wiring harness in LEFT REAR door, I found no issue. However, now "FRONT LEFT door ajar" message appeared on dash along with "LEFT REAR door ajar." Also a litany of other warning lights involving cameras, emergancy braking, etc. came on. While attempting to drive to dealership to have them inspect the issue. The wiring harness behind the back seat on the RIGHT SIDE of the vehicle began smoking. Smoke began billowing from behind the seatbelt opening in the plastic trim on the backside of the door frame.
