Owner Narrative

The engine in my 2017 Ford Escape EcoBoost experienced a known “coolant intrusion” defect in which engine coolant leaks into the engine cylinders. This defect is widely associated with the 1.5L and 2.0L EcoBoost engines and can cause engine misfires, coolant loss, overheating, corrosion, and catastrophic engine failure requiring engine or short-block replacement. The vehicle is available for inspection upon request. The vehicle is driven by a college student traveling away from home. The coolant intrusion defect creates a serious safety concern because the engine can suddenly misfire, lose power, overheat, or fail unexpectedly while driving. A sudden engine failure could place the driver and others at risk, especially during highway driving or in remote areas. The issue developed shortly after the vehicle was purchased from a dealership in June 2025. The symptoms are consistent with the widely documented Ford EcoBoost coolant intrusion defect acknowledged by Ford through Customer Satisfaction Program 21N12. The vehicle has exhibited symptoms including coolant loss and engine performance concerns consistent with this known defect. The dealership has been notified of the issue. The dealership has been contacted regarding the issue.
