Ford Fusion coolant leak leading to engine replacement needed on Ford Fusion

Some Ford Fusion owners report experiencing significant coolant leak issues, particularly in models equipped with the 1.5-liter GTDI engine from 2017 to 2019. This coolant leak can lead to engine overheating and an increased risk of fire. Additionally, some owners have noted that coolant can seep into the engine cylinders, resulting in damage that may require a complete engine replacement. Reports indicate that coolant leaks into the 4th cylinder can trigger engine light warnings and necessitate further repairs. Dealerships have recommended engine replacement as a fix for detected coolant leaks. The problem has been linked to a design flaw that allows coolant to enter the cylinders, especially during overheating incidents. Due to the severity of this safety defect, Ford has initiated recalls for certain vehicles to mitigate potential fire risks.
