NHTSA Complaint #11660208 — 2019 FORD FIESTA

•Make: Ford •Model: Fiesta ST •Model Year: 2019 •Engine: 1.6L EcoBoost •Mileage at Incident: 95000 Component Affected: Engine / Cooling System Summary of Problem: Coolant is leaking into the combustion chamber of my 1.6L EcoBoost engine due to a suspected internal engine defect. This issue caused noticeable white smoke from the exhaust, engine misfires, and a loss of power while driving. The coolant loss was not visible externally, indicating internal leakage. After diagnostic testing at a Ford dealership, I was informed the engine block or cylinder head is compromised, allowing coolant intrusion into the cylinders. The dealer quoted approximately $12,000 for a full engine replacement and confirmed that this is a known issue with Ford EcoBoost engines. Safety Concerns: The vehicle became unreliable and unsafe to drive, especially at highway speeds, due to the misfiring and sudden power loss. If this failure had occurred during certain driving conditions, it could have led to an accident. Furthermore, the cost of repair is unreasonably high for a systemic engine defect not caused by consumer neglect. Request for Investigation: This appears to be part of a broader, well-documented problem with various EcoBoost engines across Ford’s lineup ( TECHNICAL SERVICE BULLETIN 19-2346 2.0L EcoBoost - Coolant In Cylinders, White Exhaust Smoke And/Or Illuminated MIL). I am submitting this complaint in hopes that NHTSA will investigate the safety implications of this engine defect and push for accountability from Ford through recalls or reimbursement programs.
