XL / XLT / Lariat / King Ranch / Platinum / Limited (4th gen P558, 2017–present)
Monitor
The Super Duty F-250 is the workhorse of the truck segment — built for heavy towing and payload. The 6.7L Power Stroke diesel is the towing king but requires DEF and has injector/turbo maintenance. The 6.2L/7.3L gasoline V8s are simpler. Main buyer risks: diesel injector failure at high mileage, turbo oil supply tube (known diesel issue), transmission wear from heavy towing, and cab/frame corrosion on work trucks.

Top concern
Diesel Engine / Transmission / Electrical
Diesel Engine (6.7L Power Stroke)
Fuel injector wear at high mileage
High Risk at 150k+ diesel
Power Stroke injectors are expensive and wear on heavy-use trucks. A full set replacement is $3,000–$5,000.
Test cold-start idle quality. Any rough running, smoke, or misfires = request injector test.
Est. cost: $3,000–$5,000 full injector setSource: Ford Power Stroke maintenance pattern
Turbocharger oil supply tube (CP4 related)
Monitor
The CP4.2 high-pressure fuel pump had metal contamination issues on early 6.7L builds. Later builds improved.
Ask for fuel system service history. Any HPFP replacement documented = healthy sign the issue was addressed.
Est. cost: $2,000–$8,000 if HPFP failsSource: Ford 6.7L CP4 pattern
DEF system maintenance
Low Risk
Diesel Exhaust Fluid top-up every 5k miles and SCR catalyst service.
Check DEF level and confirm no emissions fault codes.
Est. cost: $50/fill-up + periodic SCR serviceSource: Ford DEF standard
Gasoline (6.2L / 7.3L)
6.2L / 7.3L Godzilla V8 — simpler and reliable
Low Risk
Both gasoline engines are straightforward and reliable. No significant failure modes.
Standard cold-start and oil check.
Est. cost: Routine maintenanceSource: Ford Godzilla V8 reliability
Heavy Work History
Transmission wear from towing
Monitor
Super Duties used for max-payload towing experience accelerated transmission wear. Check fluid color and records.
Request transmission fluid service records. Dark fluid with particles = worn.
Est. cost: $300–$500 fluid service; $4,000+ rebuildSource: AutoVetting editorial
Hitch and frame wear
Monitor
Inspect 5th-wheel or gooseneck hitch bed for heavy use signs.
Inspect bed floor for 5th-wheel mounting wear. Check frame rails for stress cracks near hitch.
Est. cost: VariesSource: AutoVetting editorial
Documentation
Commercial use history + service records
High Risk without
Super Duties from commercial fleets have very different wear profiles than personal-use trucks.
Request Carfax for fleet/commercial history. Ask for all service records including diesel service.

NHTSA Recalls (verify completion via VIN)
20V-576
Front axle wheel-end yoke may not be welded to the axle tube (2019 F-250/F-350 4x4)
On 4x4 trucks the front axle wheel-end yoke may not be properly welded to the axle tube, and a failure there costs you control of the truck. Scope is the 2019 F-250 and F-350 4x4 in both single and dual rear wheel configurations, so this is a this-truck campaign and not a Super-Duty-wide one. Remedy: free dealer inspection of the weld location, with the axle assembly replaced if the weld is misplaced.
19V-688
Rear axle shaft can fracture on electronic-locking-differential trucks (2019 F-250/F-350)
The passenger-side rear axle shaft can fail prematurely from a material defect on trucks built with the electronically locking rear differential. A broken shaft means loss of drive power and the truck cannot be held in Park, so if the parking brake is not set it can roll away. Remedy: free dealer inspection of the passenger-side shaft, replaced as needed.
18V-894
Engine block heater cable can short and overheat wiring (2017-2019 Super Duty)
Water and road contaminants corrode the block-heater cable splice connector; prolonged corrosion causes a resistive short that overheats or melts the wiring and raises fire risk. It matters most on northern and work trucks that actually plugged the heater in. Remedy: dealers first disabled the block heater cable and later replaced it, free of charge, so a truck whose block heater simply does not work may be parked at the interim fix rather than the final one.
19V-633
Front seat recliner may be missing a pawl (2019-2020 Super Duty, manual recliners)
Manual seat-back recliners can be missing a third pawl, which leaves the seat back loose and out of compliance with the federal seating standard, so it may not adequately restrain an occupant in a crash. Remedy: free dealer inspection of the seat structure with replacement as needed. Worth checking by hand on a truck whose seat back feels loose, since the defect is physical and present from new.
