1999 Ford F-350. Parked in driveway. Fire in the engine compartment. Source appears to be just behind the air filter box in the area of the master cylinder. Most of the electrical harness destroyed. Driver side battery melted down. Denver fire had to respond to put out the fire. I was never notified of a recall and this vehicle has been serviced at least twice by the local Ford dealership.
