2017 Ford Fusion: engine overheating

Filed Sep 28, 2026 · Acceleration, Engine · CA

We purchased this 2017 Ford Fusion 1.5L EcoBoost in August 2022 at 48,968 miles. At 55,940 miles, the vehicle developed a documented coolant leak requiring water-pump replacement. At approximately 75,520 miles, the coolant level was again documented as requiring attention. At approximately 84,189 miles, the vehicle experienced low coolant, low oil, white/gray smoke and rough running. Manteca Ford identified Ford TSB 22-2322 and ultimately performed a major short-block replacement. Despite this major engine repair, mechanical and drivability problems continued. At approximately 101,375 miles, we returned the vehicle to Manteca Ford specifically for loss of power and hesitation. The Ford technician verified a “noticeable loss of power” and lack of full boost. Manteca Ford diagnosed and replaced the turbocharger. The problem was not resolved. Only approximately 205 miles later, at 101,580 miles, the vehicle returned to Manteca Ford because it was still hesitating during acceleration. Manteca Ford then identified DTCs P0729, P07AA, P2703 and P2704 and documented “TRANSMISSION INTERNAL MECHANICAL FAULTS,” including an incorrect sixth-gear ratio and friction-element faults. The dealer recommended replacement or teardown of the transmission. We are extremely concerned about the safety implications of this history. Loss of power and hesitation during acceleration can create a serious hazard when merging onto a highway, entering or crossing traffic, or attempting to accelerate to avoid a collision. This vehicle has experienced repeated engine/powertrain problems despite major repairs, and we are concerned the transmission condition may have been developing during the earlier loss-of-power/hesitation complaints. We request that the federal safety agency evaluate this history for a potential safety-related defect or broader pattern.

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 the federal safety agency 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.

I am the owner of a 2017 Ford Fusion with 61,000 miles on the odometer. Please note that I have always taken good care of my car, having it serviced promptly when required. In recent weeks, I have had to replace my complete steering rack (cost $4,500) and two weeks later, my 1.7-liter Ecoboost engine due to a coolant leak into the number two cylinder at a cost of $6,700. Ford has known about both problems for years and they have resulted in both class action and small claims suits against the company. Regarding the engine, Ford issued Customer Satisfaction Program 21N12, Technical Service Bulletin TSB 22-2134 and Customer Satisfaction Program 19B37 - Supplement #4 to replace the car's engine short block. This covered cars for 7 years of service or 84,000 miles - with, as quoted in the Ford memo sent to dealers on June 9, 2022, "coverage automatically extended to subsequent owners," for presumably the life of the car. Since this is clearly a manufacturing error (as Ford admits in its June 9, 2022 memo to dealers) and not due to negligence on my part, I should be reimbursed for my expenses. the federal safety agency should also open a recall case on this matter for owners like myself.
