•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 the federal safety agency will investigate the safety implications of this engine defect and push for accountability from Ford through recalls or reimbursement programs.

Catastrophic Engine Failure due to the manufacturer's recommendation and use of conventional motor oils in the form of Synthetic Blend Motor Oil or Super Premium Motor Oil, a specification WSS-M2C945-B1 , from the 2019 Ford Fiesta Owner Manual. It leaves the driver and occupants stranded in the middle of the road with an inoperable vehicle. Being a small 4 cylinder engine the engine is high revving and produces sludge. Whereas if the manufacturer recommended Full Synthetic oil as the car parts store do as part of the oils usable for that specific model. There would have been no engine failure as occurred with my vehicle on 11/22/2022. No sludge would form in the engine. Because synthetic oil is proven not produce any sludge in an engine. I believe a recall should result in the manufacturer recommending full synthetic in the owner manual and engine oil be replaced by dealer service to full synthetic as well as engine work be done due to damage from conventional oil.

In SEP-2021, the engine overheating warning light came on. We stopped the car and realized that the coolant level in the overflow reservoir was very low. There was no obvious leak on the ground or on the engine. We purchased coolant and topped off the coolant reservoir to the appropriate level. A couple of weeks later, we noticed again that the coolant level had gone down significantly while there was no sign of coolant whatsoever on the floor of the garage. We dropped off the car at our local Ford dealer on 20-OCT-2022 for a diagnosis. On OCT-22, the service department confirmed that the engine had overheated and that the head gasket had blown and informed us they would contact Ford to discuss the repair. Further feedback from the dealership was that they would need to tear down the engine at Ford's request for further investigation. We received a loaner vehicle from the dealership on 29-OCT-2022. Fast forward to FEB-2022 and the dealer confirmed that they had found no external leaks and the diagnosis had revealed codes P1299 and P0303. Further testing revealed coolant found in cylinder # 3 so the coolant was found to be leaking inside the engine. Engine block was found to be cracked. They also confirmed that Ford Motor Co. had agreed to replace the engine under warranty. The repaired vehicle was finally returned to us on ... 20-JUN-2022, 8 months after it was dropped off at the dealership.
