What stands out
Engine accounts for 38% of every owner complaint on file for this vehicle — the dominant problem area across 12 categories tracked.
Owners have filed 415 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2017 Ford Fusion, particularly with 1.5L and 2.0L EcoBoost engines, has a well-documented defect where coolant leaks into cylinders through cracks in the engine block, causing expensive engine failure (typically $5,000–$13,000 repairs) often at 40,000–120,000 miles. Ford's partial recalls and customer satisfaction programs exclude many VINs despite identical defects, leaving owners responsible for thousands in repairs even on vehicles with low mileage.
The 2017 Ford Fusion is experiencing a widespread defect involving coolant intrusion into the engine cylinders through cracks in the block or thin metal walls between cylinder bores and water jackets. Owners report the problem strikes across a range of mileage—from as low as 40,000 miles to over 120,000—with no predictable pattern.
The typical sequence starts with a check engine light and misfire codes (P0301–P0304). Owners take the car to a mechanic, who recommends spark plug and coil pack replacement ($350–$600). That fix lasts days or weeks before the light returns. Meanwhile, owners notice coolant levels dropping with no visible leaks underneath, white smoke from the exhaust on startup, and overheating warnings. A second mechanic or dealer then runs a pressure test or scope and delivers the hard diagnosis: coolant is inside the cylinders, the engine needs replacement, and the bill is $4,800 to $13,000.
Ford has issued Technical Service Bulletins (22-2229, 19-2139) acknowledging the defect and acknowledging the fire risk. Customer Satisfaction Programs 19B37 and 21N12 exist for short block replacement, but with narrow VIN and mileage windows (typically capped at 84,000 miles). Owners report their VINs are excluded despite having identical symptoms, and dealerships cite mileage overages as the reason for refusal. Some owners report the same defect recurring on replacement engines within 2–5 years. Ford has not recalled the 2.0L EcoBoost engine despite identical failures, and owners frequently find themselves driving cars flagged with safety risk but unable to afford the repair or secure coverage.

Failure modes owners describe
Coolant intrusion into cylinders
Coolant leaks from the engine block into the cylinder bores through cracks or thin walls between cylinder walls and water jackets. This contaminates the combustion chamber, fouls spark plugs, causes cylinder misfires, and eventually leads to catastrophic engine failure if not addressed.
When: Typically between 40,000 and 130,000 miles; some failures reported as early as 40k miles, others at 80k-120k miles
Symptoms owners cite: Check engine light illumination, often flashing; Cylinder misfire codes (P0301, P0302, P0303, P0316, P0300); Rough idle or rough starting; Continuous loss of coolant with no visible external leaks; White/sweet-smelling exhaust smoke; Engine overheating warnings; Poor acceleration and lack of power; Inability to exceed certain RPM or speed; Engine stalling or shutdown while driving
Codes mentioned: P0301 - Cylinder 1 misfire, P0302 - Cylinder 2 misfire, P0303 - Cylinder 3 misfire, P0304 - Cylinder 4 misfire, P0316 - Cylinder 1 misfire on startup, P0300 - Random/Multiple cylinder misfire
Repairs/costs cited: Complete engine replacement required; short block replacement performed under some Ford customer satisfaction programs. Owners report costs ranging from $4,800 to $13,000+ for new engine installation. Spark plug replacement and coil pack replacement are temporary measures that do not resolve the underlying issue.
Recalls/TSBs owners mention: Ford Technical Service Bulletin 22-2229 documents coolant in cylinders and engine misfire. Customer Satisfaction Program 19B37 (powertrain control module reprogramming) and 21N12 (short block replacement) exist for certain VINs and mileage thresholds, typically capping coverage at 84,000 miles. Many owners report their VINs are not included in coverage despite having identical symptoms. Ford has issued TSB 19-2139 and 20-2100 acknowledging the issue but has not recalled the 2.0L EcoBoost engine or all affected 1.5L models. Dealers frequently deny coverage citing mileage limitations and VIN exclusions.
Engine block cracking and failure
The engine block develops cracks, particularly between cylinder walls and water jackets, due to a manufacturing defect or design flaw in how thin the metal walls are machined. This allows coolant to enter the cylinders and eventually causes complete engine failure with loss of compression.
When: Typically 50,000 to 120,000 miles; one case reported at 28,000 miles on a replaced engine
Symptoms owners cite: Loss of engine compression; Cylinder wall scoring visible on inspection; Engine seizing or locking; Complete loss of power while driving; Oil intrusion into coolant or vice versa; Multiple engine misfire codes; Engine overheating
Codes mentioned: P0300 - Multiple cylinder misfire, P0301 - P0304 - Individual cylinder misfires
Repairs/costs cited: Complete engine replacement is the only repair; quoted costs $4,800 to $13,000+. Some owners report the same defect recurring on replacement engines within 2-5 years and 50,000 miles.
Recalls/TSBs owners mention: Ford acknowledges the defect in TSB 22-2322 (which notes fire risk) and TSB 22-2229. Short block replacement programs (21N12, 19B37) exist for select VINs. Ford denies coverage for vehicles outside mileage/VIN parameters and refuses to extend coverage or recall 2.0L engines despite identical defects in 1.5L engines being recalled.
Spark plug fouling and repeated misfires
Coolant leaking into cylinders fouls spark plugs and coil packs, causing repeated engine misfire codes. Replacing spark plugs and coils is a temporary fix that fails within days to weeks as the underlying coolant intrusion continues.
When: Can occur early in the coolant intrusion process, sometimes before other symptoms manifest
Symptoms owners cite: Check engine light with misfire codes; Spark plugs contaminated with coolant residue; Rough idle; Hesitation or jerking during acceleration; Engine shaking or vibration
Codes mentioned: P0301 - Cylinder 1 misfire, P0302 - Cylinder 2 misfire, P0303 - Cylinder 3 misfire, P0304 - Cylinder 4 misfire
Repairs/costs cited: Owners report $350 to $600 for spark plug and coil pack replacement. This repair is temporary and fails repeatedly, leading to eventual engine replacement diagnosis.
Recalls/TSBs owners mention: No specific recall or extended coverage for repeated misfire repairs. Owners are often told to replace spark plugs and coils at their own expense before the true coolant intrusion issue is diagnosed.
MAF sensor failure causing engine shutdown
Mass Air Flow sensor failure causes the engine to shut down without warning and without a preceding check engine light, potentially leaving the driver stranded in traffic.
When: Reported at 70,000+ miles
Symptoms owners cite: Complete engine shutdown without warning; No check engine light before failure; Engine unable to restart immediately
Codes mentioned: MAF sensor fault (part 8V2Z12B579A cited)
Repairs/costs cited: MAF sensor replacement required. No cost cited in narratives.
Recalls/TSBs owners mention: No recall or manufacturer response noted in narrative.
Engine oil leak from oil pan and gasket
Oil pan gasket and RTV seal fail, causing oil to leak onto the driveway and into the passenger cabin via air conditioning intake. Repeated repairs on the same vehicle.
When: Reported at approximately 40,000 miles
Symptoms owners cite: Oil spotting on driveway; Oil odor in passenger cabin when air conditioning is used; No warning lights initially
Repairs/costs cited: Oil pan gasket, valve covers, and RTV seal replacement. Repair was performed multiple times on the same vehicle without permanent resolution.
Recalls/TSBs owners mention: Related to Ford Technical Service Bulletin 23-2075 (Oil Leak from Engine Oil Pan RTV Seal). Repair was performed under what appears to be a known issue.
Engine overheating with internal coolant loss
Engine overheating warnings occur despite coolant reservoir appearing full or even after being topped off. No visible external leaks, indicating internal coolant intrusion into cylinders.
When: Can occur at any mileage where coolant intrusion is developing
Symptoms owners cite: Engine overheating warning light or message; Coolant reservoir empty or low with no visible external leaks; Coolant needing refilling frequently (sometimes daily); Flashing coolant temperature warning; Audio warning accompanying temperature warning
Codes mentioned: Coolant temp high code (specific code varies)
Repairs/costs cited: Coolant top-off is temporary; engine replacement is the only permanent solution.
Recalls/TSBs owners mention: No specific manufacturer response to overheating separate from coolant intrusion response.
