2016 Jeep Wrangler electrical problems

Multiple reports of uncontrolled fires in the engine compartment, often originating near the fuse box, battery, or wiring harness on the right side of the engine. Fires have occurred while driving, during test drives, while parked, and after recent dealership service. Fires spread rapidly, melting through the firewall into the cabin, and have resulted in total vehicle losses.
