Verbatim from NHTSA complaints, newest first
“Engine failure due to a faulty design from Ford Motor company. Coolant intrusion is the root cause due faulty engine design on the 2016 Ford Fusion 2.0 ecoboost engine.”
“2016 Ford Fusion 1.5L Ecoboost engine w/approx. 88,000 miles was just purchased from private owner on 10/7/26. On 10/17/26 the check engine light came on and showed problem with cylinder 1 and 4. Car was running ruff, misfiring, losing power. Safety issue for losing power on highway. New spark plugs installed and cylinder 1 and 4 replaced. Replaced cylinder 4 twice but this did not work. Local auto shop scoped car as well as did pressure tests. Coolant Intrusion into cylinders. Defective head gasket and design of engine. Car needs engine replaced. Coolant intrusion with defect of the engine should be a recall from Ford.”
“Ford Ecoboost coolant intrusion. Loss of coolant without noticeable leaks. Loss of power while experiencing cylinder misfire. After cool-down, engine runs rough with white tailpipe smoke and generates check engine light for cylinder misfire.”
“We are having issues with the 2.0 ecoboost engine overheating and going into limp mode and i had it looked at and was told it has the defective engine that FORD knows about and should fix because we can’t afford to buy a new engine and it’s not my fault that the engine is defective”
“My antifreeze AND oil keep going empty after driving the car after so many days..... there is no leak on the ground, and i do not smell anything inside the cab. No lights are on the dash I took it and has them plug it in just incase and the only thing that came back as a possible issue is the brake pad. Otherwise they said there was no issue However, there is an issue and no one can seem to figure out what it is!”
“Exhibited signs of a coolant leak followed by throwing a code about cylinder 4 misfiring. Took my car to the dealer who confirmed that there is coolant leaking into cylinder 4, and it is similar to other defects found in many 1.5 liter ecoboost engines from this model line. Was told that my VIN did not qualify for the recall that is only for the ecoboost 2.0 liter engines even though they have the same defect.”
