2017 Ford Fusion

I am submitting this complaint regarding a serious engine failure and safety issue involving my 2017 Ford Fusion equipped with the 1.5L EcoBoost engine. At approximately 79,000 miles, my vehicle experienced a coolant intrusion failure. While driving, the engine suddenly stalled in the middle of an intersection, leaving me stranded in traffic and at risk of being rear-ended by approaching vehicles. I was able to restart the vehicle and move out of the intersection, but the exhaust then produced a very large, thick cloud of white smoke. The amount of smoke could have significantly reduced visibility for other drivers and created an additional safety hazard. I took the vehicle to a Ford dealership, where I was told the engine had coolant intrusion and needed to be replaced. I was also told this is a common problem with Ford EcoBoost engines, including the 1.5L, 2.0L, and 2.3L engines. My concern is not only the cost of the repair, but the serious safety risk. Coolant intrusion can cause misfires, excessive white smoke, engine damage, and eventual engine failure. A sudden loss of power while driving can create a serious crash hazard, as happened to me. I am concerned Ford has known about this recurring problem for years yet has continued using these engines in vehicles such as the Fusion, Escape, and Lincoln MKZ without adequately addressing the issue. I request that NHTSA investigate coolant intrusion affecting Ford EcoBoost engines and determine whether a safety defect exists that warrants a recall. I also believe affected owners should receive reimbursement for engine replacement costs when the failure is caused by this defect. My experience demonstrates that this is more than a normal maintenance issue. An engine that can suddenly stall in traffic and produce a large cloud of white smoke without warning poses a significant safety risk to vehicle occupants and other motorists.

The contact owns a 2017 Ford Fusion. The contact stated that while driving 60 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle lost motive power, and the RPM became elevated. In addition, the contact became aware of an abnormal odor. The contact referenced an unknown recall; however, the VIN was not associated with a recall associated with the failure. The failure mileage was approximately 150,000.

2017 Ford Fusion. Transmission replaced February 2026 at 98,175 miles by independent repair facility. Check engine light illuminated immediately following replacement and has remained on continuously since. Autozone scan showed emissions-related code only. On August 28, 2026 at approximately 120,064 miles, orange wrench light and "See Manual" message appeared moments after hot restart. Acceleration became heavy and hesitant. Drove approximately 70 miles home via I-15; heavy traffic required engine shutdown at multiple stops. Following morning, wrench light was no longer illuminated but hesitation persisted. Using manual paddle shift to select 5th gear improved drivability. Replacement transmission accumulated approximately 22,000 miles over 6 months. Ford Motor Company has issued multiple recalls for 2013-2016 model year Fusions involving identical transmission, shifter cable bushing, and torque converter defects, but 2017 model year vehicles with identical 6F35 transmissions and failure symptoms have been excluded from all campaigns. No crash, fire, or injury occurred.

If i do not run my car for atleast 10 minutes before driving, my gas tank will start making a loud horn sound, and when this happens and i go to slow down, the car will shut off. Mechanics say there’s an issue with the purge valve and the charcoal filter. I’ve already had this issue fixed three times and it comes back less than a week prior to service

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.

The vehicle in question has the coolant intrusion into cylinders 2 and 3 with rough idle on startup, P0300, P0302, P0303, and white smoke on startup. The vehicle now has 111339 miles on it and the out of pocket cost is more than what the vehicle blue books for in excellent condition. TSB 22-2134 speaks to all the issue and what the repair is. If this is a known issue then I feel this should be a vehicle recall by Ford due to the costly repair.

ENGINE HAS COOLANT INTRUSIONAND IS MISFIRING. Engine light came on. The coolant system found pressure to be dropping significantly. Removed spark plugs and inspected cylinder bores using borescope. Verified coolant is leaking into cylinder 2 and needed to replace the engine at Ourisman Ford in Manassas VA. on July 11, 2026.

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 NHTSA should also open a recall case on this matter for owners like myself.

1.5 liter ecoboost engine has a coolant intrusion problem into the cylinder to due a design flaw. Problem can cause several problems: loosing coolant and causing the engine to overheat, causing misfire in the cylinders, and can cause the engine to stallwhich has happened several time on me. The engine should be recalled as a safety concern for stalling, it has stalled on the I15 in Utah several times

Noticed that the coolant level kept going down with no apparent external leakage and was also getting a code for #2 Cylinder Mis-Fire, After adding a total 1 gallon antifreeze i made an appointment at the local Ford Dealer to see what is wrong. They Diagnosed the Issue to Coolant leaking in to Cylinder #2, there recommendation is to replace Long Block.
