I am reporting a serious recurring safety concern involving a 2017 Ford Fusion SE with a 1.5L EcoBoost engine. The vehicle was purchased used in August 2022 with approximately 50,000 miles. Within months, significant coolant and engine problems began. In February 2023, at approximately 55,940 miles, the vehicle developed a coolant leak. A pressure test confirmed the water pump was leaking and it was replaced. At approximately 84,189 miles, the vehicle experienced white/gray exhaust smoke, coolant loss, very low oil, and rough-running symptoms. The servicing Ford dealership referenced Ford Technical Service Bulletin (TSB) 22-2322 in connection with the diagnosis and ultimately replaced the engine short block. Despite this major engine repair, the problems continued. The vehicle subsequently experienced additional smoking, hesitation and loss of power and required replacement of the turbocharger. The vehicle was returned again because it continued to smoke and required additional repairs. I am concerned this is a recurring engine defect rather than normal wear and tear. The repeated engine/coolant failures, smoking, hesitation and loss of power create a serious safety concern because the vehicle may unexpectedly lose power or experience engine failure while being driven. Ford has been notified of the repeated failures but declined further relief based primarily on the vehicle's current age, mileage and expired warranty. This ignores that the problems began years earlier at substantially lower mileage and that major repairs failed to permanently correct the condition. I request that NHTSA investigate whether the 1.5L EcoBoost engine in this and similarly equipped Ford vehicles has a safety-related defect involving coolant intrusion, engine failure and loss of power. The vehicle is currently at approximately 101,000 miles, but the documented problems began at 55,940 miles and continued despite major repairs.
