Failed component was the upper fuel filter/ fuel filter connecting lines located on top of the 6.7 power stroke engine broke and poured diesel all over the engine and into the valley causing the engine and engine bay to catch on fire while driving down the road. Safety was the fact that our entire truck burnt down and there was extreme risk of loss of life and ended up total loss of property. There have been multiple cases of power strokes from 2011-2026 equipped with the 6.7L power stroke diesel engine having this exact same problem due to the poor placement and inadequate materials to be used in high pressure fuel lines and filters. The vehicle was inspected by insurance and they did determine that was the cause of the fire. There were no warnings, we started smelling something and then smoke began coming through the vents. …

Wife was driving the truck(I was the passenger) while towing our dump trailer. After approx 100 miles into this trip the dash showed a "Reduced Engine Power Warning", and then shuddered. That was immediately followed by a "Service Engine Soon" warning on the dash, and the truck shut down as we were pulling to the shoulder. I smelled diesel fuel as we slowed to a stop. I got out and saw some smoke coming from under the hood. I looked under the truck and saw burning material falling from underneath, I shouted fire, and my wife exited while I retrieved our dog from the back seat. The cab was filling with smoke. Wife called [redacted] while I retrieved a few more small items from back seat. We stepped back and the truck was fully engulfed in flames in a few minutes. Fire crews were on scene after several more minutes, and by that time the truck was burnt to the ground. …
