2014 Subaru Outback engine problems

Spontaneous engine fire while driving - mar 07,2019 - 2014 subaru outback with current maintenance and no prior history of malfunction. During a 2.1 mile drive on city streets electrical disturbances of the radio/media console were noted, followed shortly thereafter by black smoke from under the hood. The car was immediately pulled to the side of the road. Upon exiting the car, the smoke had become white and flames were noted under the car. The front of the car soon became engulfed in flames.

Outback 2.5l. We noticed oil consumption after the 3-4th oil change. All oil changes were preformed at subaru dealership ( browns manasssas or sheehy springfiield). We asked why we were having to add oil and told that this was normal. The situation has gotten worse with low oil light coming on at about 4,000 miles on the oil change. We notified subaru headquarters and they suggested an oil consumption test. That was the first time that had been suggested. The mileage was about appx 72,000 miles.
