I own a 2017 Ford Escape equipped with the 2.0L EcoBoost engine. I am experiencing a known issue related to engine coolant intrusion into the cylinders, which has been reported by many owners and acknowledged by Ford through Customer Satisfaction Program 21N12. This issue involves coolant leaking internally into the combustion chamber—usually due to a flawed cylinder head casting—which can cause engine misfires, white exhaust smoke, rough idling, overheating, or complete engine failure. In my case, a coolant pressure test was performed, and it confirmed that the cooling system is losing pressure, which is consistent with internal coolant leakage into the engine. Despite this, Ford has declined to cover the repair under the 21N12 program, stating that my vehicle is not eligible by VIN, even though it is the correct model year and engine. I believe this constitutes a safety issue, as the engine could fail at highway speeds without warning, and Ford has failed to provide adequate support for vehicles that clearly exhibit the documented failure pattern. I am requesting the NHTSA investigate this issue further, including why certain 2017 Escapes with the affected 2.0L EcoBoost engine are being excluded from coverage despite confirmed symptoms.
