The turbocharged four behind the Escape and Fusion of the early-to-mid 2010s — an engine whose coolant intrusion issue became serious enough to prompt a manufacturer recall and, in some cases, vehicle buybacks.
A cracked cylinder head on certain production examples allowed coolant to intrude into the combustion chamber, in some cases leading to engine fires — serious enough that Ford issued a formal recall covering affected model years. Any buyer considering this engine should treat recall history as the very first thing to check, well ahead of anything else on this page. Examples that received the recall repair, or that were built outside the affected production window, carry a much lower risk profile.
Not a guarantee, but a pattern seen consistently across owner forums and independent-garage reporting.
The coolant intrusion issue has been reported across a range of mileages and is tied to a production defect rather than purely wear-related.
Mileage after a confirmed recall repair is a meaningfully lower-risk indicator than mileage alone on an unconfirmed car.
This is non-negotiable: check the vehicle's recall history by VIN through the manufacturer's official lookup tool before considering anything else about this car.
If the recall shows as open rather than completed, treat this as a serious concern rather than a minor administrative detail.
Ask for documentation of the specific repair performed, not just a general statement that recall work was done.
