For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.

What stands out
Owners have filed 26 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.
No new NHTSA engine complaint has been filed on this vehicle in over 4 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Some 2014-2020 Fusion and 2017-2019 Escape vehicles may be equipped with a 1.5L Ecoboost engine that uses a 50-tooth variable camshaft timing (VCT) intake and exhaust unit from the assembly plant or if a service long block was installed. VCT locking tool 303-1097 is not compatible with this system. If VCT system service is required, replace both the intake VCT (service part DS7Z-6256-F) and exhaust VCT (service part DS7Z-6256-G) as a pair. An interim loaner tool program has been established to enable these repairs. Contact 1-800-403-4844 (Monday-Friday 8:00am to 8:00pm EST; Saturday 8:00am to 3:00pm EST) to obtain this tool.

The failure pattern owners describe
The 2020 Ford Fusion engine displays recurring failures across multiple systems. Flex plate cracks are the most commonly cited issue, producing rattling or knocking sounds during idle or with AC running—typically starting around 45K miles and progressing. Ford issued a customer satisfaction program (22N12) in 2022 but only covers 2.0L engines, leaving 1.5L owners paying out of pocket despite reporting identical symptoms.
Coolant intrusion into cylinders appears in multiple narratives: coolant migrates internally despite a full reservoir, causing overheating, white exhaust smoke, and engine block failure. One owner noted zero compression in two cylinders at 96K miles on a 1.5L EcoBoost. Other reported failures include head gasket breakdown, purge control valve failure, and camshaft thrust plate damage.
Most owners report no warning lights before failure or only a check engine light after the problem develops. When vehicles are diagnosed, repairs typically mean engine replacement—a five-figure job that goes unpaired in nearly every narrative because warranty denies coverage or the cost is prohibitive. Dealers consistently refer owners to NHTSA rather than offering assistance. One owner found a class action lawsuit addressing coolant intrusion in earlier Fusion models (2013–2019), suggesting this is not a new problem.
