Owners of 2020 Ford Expeditions describe persistent powertrain failures starting at relatively low mileage. The most frequent complaint centers on transmission problems: hesitation or complete refusal to engage gears, hard shifts that feel like "metal hitting metal," jerking and shuddering during gear transitions, and transmission slipping while driving. One owner's transmission underwent complete teardown and rebuild at 30,000–40,000 miles, then failed identically within a year and required full replacement. Dealerships have been unable to duplicate or fix the problem despite multiple visits, though a technical service bulletin exists.
Engine-side failures include premature timing chain stretch (between 83,000–98,800 miles) triggering codes P0011, P0012, and P0016, along with rattling noise and shuddering. Cam phasers fail around 97,000 miles. Front cover seals leak oil and introduce metal shavings into the cylinder, with one owner's replacement seal failing again. Catalyst converters have failed three times on one vehicle by 20,000 miles. Coolant hoses rupture at under 74,000 miles; the service department notes this is occurring frequently, suggesting a design defect. One owner reports sudden engine shutdown while driving. Multiple owners state Ford knows of these widespread issues but has provided no fix, and recall parts remain unavailable.
Failure modes owners describe
Transmission hesitation, slipping, and gear engagement failure
The transmission fails to engage gears smoothly or at all, sometimes dropping into neutral momentarily during acceleration or lane changes. Owners report hard shifts, jerking during gear transitions, and transmission temperature rising to 240°F. The condition has persisted for months despite multiple dealership visits with no solution found.
When: Multiple failures across various mileages; some reported 6+ months of ongoing problems
Symptoms owners cite: Hesitation or refusal to engage gears during speed changes; Vehicle dropping into neutral momentarily on highway passing maneuvers; Hard, metal-on-metal shifting sensations; Jerking and shuddering during gear transitions; Transmission temperature rising to 240°F; Transmission slipping while driving
Repairs/costs cited: One owner reported transmission underwent complete teardown and rebuild in April 2023, then failed again with identical symptoms in May 2024 requiring full replacement. Dealership unable to duplicate problem; technical service bulletin exists but no permanent fix applied
Recalls/TSBs owners mention: Ford aware that thousands experiencing these dangerous situations but has no solution. No recalls or recalls parts unavailable
Engine timing chain stretch and camshaft timing issues
The camshaft timing chain stretches prematurely, causing timing misalignment in one or both cylinder banks. Associated components including phasers and variable valve timing solenoids also fail. The condition produces rattling noise and triggers check engine codes.
When: Failures occurring between approximately 83,000 and 98,800 miles
Symptoms owners cite: Abnormal rattling sound from engine at startup or while running; Check engine light illuminated; Vehicle shuddering and jerking while shifting; Powertrain fault message displayed
Codes mentioned: P0011, P0012, P0016
Repairs/costs cited: Requires replacement of stretched timing chain in one or both banks, along with pretensioners, phasers, and variable valve timing solenoids. One owner's vehicle not repaired; repairs not completed
Failed front cover seals and engine oil leak with metal contamination
Front cover seals fail, causing oil leakage and metal shavings to enter the cylinder. The owner reports the seal was replaced under warranty but failed again, followed by a coolant hose leak. Engine replacement was recommended.
When: Front cover seals failed July 2023; replacement occurred; second failure appears to have followed, at approximately 110,000 miles
Symptoms owners cite: Low oil pressure warning light illuminated; Loss of motive power; Metal shavings present in cylinder with oil leak; Subsequent coolant leak after seal replacement
Repairs/costs cited: Front cover seals replaced under warranty. Coolant hose later replaced. Engine replacement recommended but not completed
Recalls/TSBs owners mention: Manufacturer made aware; advised contact to report to NHTSA
Catalyst converter failure
Catalyst converter failed on three separate occasions at relatively low mileage, each time requiring replacement. The defect produces jerking and check engine illumination.
When: Approximately 20,000 miles with three separate failure events
Symptoms owners cite: Check engine warning light illuminated; Vehicle jerking
Repairs/costs cited: Catalyst converter replaced three times by dealer
Recalls/TSBs owners mention: Manufacturer made aware but did not assist. Owner advised to contact NHTSA
Cam phaser defects
Cam phasers fail prematurely, producing rattling noise during startup. Two owners report this issue independently at high mileage with no warning light.
When: Approximately 83,000 to 97,000 miles
Symptoms owners cite: Abnormal rattling sound at startup
Repairs/costs cited: One owner's vehicle diagnosed with defective cam phaser but not repaired; second owner's failure not formally diagnosed or repaired
Recalls/TSBs owners mention: Manufacturer informed there are no recalls and referred owners to NHTSA Hotline
Coolant hose rupture
Coolant hoses split or rupture at low mileage. Service department reports increased frequency of hose failures, indicating a systemic fault.
When: Less than 74,000 miles
Symptoms owners cite: Coolant hose splitting or rupturing
Repairs/costs cited: Hoses replaced; service department noted increased incidence of hose ruptures across vehicles
Engine stalling
Vehicle suddenly shut off while driving in normal conditions, requiring restart on the roadside.
When: One reported incident during rainy conditions
Symptoms owners cite: Sudden engine shutdown while driving
