Kestrel Take
Ford's own diesel, designed in-house after the Navistar divorce, and by 2015 it was sorted. This is the Super Duty to buy. The single genuine catastrophe risk is the CP4 fuel pump, and when it goes it takes the whole fuel system with it.
Known Issues for the 2015 Ford F-250 Super Duty (6.7L Power Stroke)
Ranked by wallet impact. These are documented, recurring problems — not freak accidents.
The CP4 runs on diesel fuel for lubrication and American fuel is drier than it likes. When the pump self-destructs it sends metal through the injectors, rails, lines, and tank. Every fuel component must be replaced.
Repair cost range: $8,000-$12,000
The variable geometry turbo sticks from soot buildup, causing underboost codes and reduced power.
Repair cost range: $2,000-$4,000
Short-trip use prevents complete regeneration, clogging the filter and eventually derating the truck.
Repair cost range: $1,000-$3,500
Hard cold starts and rough running from failing glow plugs or worn injectors.
Repair cost range: $800-$3,500
