Owners of the 2019 F-350 with the 6.7L Powerstroke report a pattern of serious engine-related failures across multiple systems. The CP4 fuel pump sheds metal shards into the fuel tank and injectors, causing complete fuel system failure and stranding owners with no warning light. Fuel filter hose connections fail due to brittle clips, spraying diesel into the engine bay—a fire hazard. The factory-welded DPF filter housing cracks at connection points, a defect Ford acknowledges but refuses to warranty, with replacement costs exceeding $6,300.
Oil pan leaks appear as early as 57,000 miles, dripping onto ground. Emissions sensors fail around 54,000 miles. MAF sensor malfunction forces trucks into limp mode and can shut the engine off suddenly. Complete engine and turbocharger failures have occurred at 84,000–87,000 miles with abnormal noises preceding failure. An oil separator issue causes sludge buildup.
Ford has issued service bulletins for known defects (DPF cracks, MAF problems, oil separator issues) but has not recalled them. Some owners were sold 2019 trucks without emissions sensors, yet Ford eliminated these sensors entirely on 2022 models—suggesting awareness of the durability problem. Dealers deny warranty coverage by classifying components like the DPF as consumables. Repair costs commonly exceed $1,000, with major failures requiring $6,300+ investment.
Failure modes owners describe
Fuel pump internal failure with metal contamination
CP4 fuel pump deteriorates internally, shedding metal shards into the fuel system. This clogs fuel injectors and damages the entire fuel system. Failure occurs suddenly with no warning light, leaving owners stranded.
When: 164,000 miles
Symptoms owners cite: Engine loses motive power while driving; Power Reduced Mode message displayed; Engine shutdown with no warning light; Metal shards found in fuel tank
Codes mentioned: Fuel system leak code, Check engine light (delayed or absent)
Repairs/costs cited: Full fuel system rebuild required. Metal contamination found in fuel tank and fuel injectors. Dealer estimate not provided in narrative.
Recalls/TSBs owners mention: Manufacturer notified; referred contact to NHTSA. No recall or TSB mentioned.
Fuel filter connection failure and fuel line deterioration
Fuel filter hose connection fails due to brittle clip material that crumbles. Diesel fuel sprays into engine bay, creating fire hazard. Hose blows off again after reattachment. Owners report this as a widespread issue online.
When: Service interval (not specified mileage)
Symptoms owners cite: Fuel line blows off at fuel filter connection while parked at stop sign; White clip holding hose crumbles apart; Fuel sprays over engine bay; Hose fails again after reattachment; Fire hazard from fuel saturation
Repairs/costs cited: Entire fuel line replacement required. Cost: approximately $1,000. Filter was being serviced per manufacturer guidelines.
DPF filter housing crack at factory weld
Factory weld on DPF filter housing cracks at the piping connection just before flange. Owners report this as a known defect on 2017–2020 F-250 and F-350 Powerstrokes. Ford acknowledges the issue but denies warranty coverage, classifying it as a consumable filter.
When: Not specified
Symptoms owners cite: Check engine code P2002 (DPF system failure); Cracked DPF filter housing at factory weld location
Codes mentioned: P2002
Repairs/costs cited: DPF filter and housing replacement required. Dealer estimate: over $6,300. Only dealer can perform replacement.
Recalls/TSBs owners mention: Ford denies warranty coverage, stating DPF is a consumable filter not covered. Known problem acknowledged by Ford.
Upper oil pan leak
Upper oil pan develops leak, dripping oil onto ground. Occurs at relatively low mileage. Multiple owners report similar failures.
When: 57,000 miles and 123,000 miles
Symptoms owners cite: Oil drips onto ground while parked; Abnormal burning odor and white smoke from under hood; No warning light illuminated
Repairs/costs cited: Oil pan replacement required. Repair not yet completed in reported cases.
Recalls/TSBs owners mention: Manufacturer notified. No recall or TSB mentioned.
Diesel particulate matter sensor failure
Particulate matter sensor fails, triggering emission fault codes. Sensor may crack internally. Ford sold some 2019 trucks without this sensor and eliminated it from 2022 models, suggesting known durability issue.
When: 54,000 miles
Symptoms owners cite: Check engine light illuminates; Emission fault code 22E02 (particulate matter sensor)
Codes mentioned: 22E02
Repairs/costs cited: Sensor replacement cost $816. If sensor is cracked, additional diagnostic cost $1,259. Owner reports this is a documented Ford problem.
Recalls/TSBs owners mention: Ford has issued service bulletins. Some 2019 trucks sold without sensor; eliminated from 2022 models onward.
Engine failure (blown engine)
Complete engine failure requiring full engine replacement. Occurs suddenly with no warning indicators. Cause not specified in complaint.
When: 84,000 miles
Symptoms owners cite: Engine failure/stoppage while driving; No warning indicators illuminated before failure
Repairs/costs cited: Engine replacement performed at Haley Ford Richmond.
Recalls/TSBs owners mention: Manufacturer contacted but specifics redacted per FOIA.
Engine and turbocharger failure
Abnormal clanking from engine compartment indicates internal engine or turbocharger damage. Both components require replacement at relatively low mileage.
When: 87,000 miles
Symptoms owners cite: Abnormal clanking sound from engine compartment; Engine and turbocharger failure
Repairs/costs cited: Engine and turbocharger replacement required. Repair not yet completed.
Recalls/TSBs owners mention: Manufacturer notified but offered no assistance.
Mass air flow (MAF) sensor malfunction
MAF sensor malfunction prevents diesel regeneration and triggers limp mode. Known issue documented in Ford service bulletin for 6.7L engines. Can cause sudden engine shutdown with little notice, leaving owner stranded.
When: Not specified
Symptoms owners cite: Truck refuses to regenerate (regen); Vehicle enters limp mode; Sudden engine shutdown possible; No warning before shutdown
Repairs/costs cited: MAF sensor service/replacement. Cost reported as over $1,100.
Recalls/TSBs owners mention: Ford issued technical service bulletin for 6.7L engines. No formal recall issued. No owner warning provided.
Oil separator sludge buildup and failure
Oil separator fails and causes sludge accumulation in engine. Ford is aware of the issue but has not issued recall or customer notification. Consequences of sludge buildup not specified in complaint.
When: Not specified
Symptoms owners cite: Oil separator failure; Sludge buildup in engine
Recalls/TSBs owners mention: Ford aware of issue. No recall issued. No customer information provided.
