2020 Ford Fusion: engine stalls while driving

Filed Aug 15, 2026 · Engine · MI

COMPONENT THAT FAILED: The engine cooling fan on my 2020 Ford Fusion SEL (1.5L, non-hybrid) became inoperable and blew three fuses. With the fans not operating, the engine overheated, destroying the head gasket and engine, requiring complete replacement. Failure occurred 07/08/2026 at 49,118 miles. WARNING SYMPTOMS: The A/C began blowing warm air roughly 2 days earlier. The engine temperature lamp illuminated on 07/08/2026 — the first and only time it ever came on. No prior overheating, no coolant loss, no leaks, no other alert. I stopped driving immediately on that single warning and had the vehicle towed. SAFETY RISK: A cooling fan failure progressing to engine destruction risks overheating, loss of motive power, and stalling in traffic or at highway speed. I stopped safely; a driver getting this same lone warning on a freeway would face a serious hazard with no notice. The vehicle's protections did not prevent a low-cost part from destroying the powertrain, and the sole warning came immediately before catastrophic damage. CONFIRMED BY INDEPENDENT SERVICE CENTERS: Yes. A certified technician at a licensed independent shop found the cooling fan assembly inoperable and identified it as the cause of both the A/C failure and the temperature warning, noting these vehicles are known to fail head gaskets this way. A second licensed engine shop documented the sequence: the electric cooling fan failed, which blew three fuses, causing an overheat condition that caused engine failure. Written findings, inspection reports, and invoices retained. MANUFACTURER INSPECTION: None. Ford declined to consider assistance unless a Ford technician inspected the vehicle, by which time it was already at an independent shop mid-repair. No police or insurance inspection. MANUFACTURER AWARENESS: Ford SSM 48659 covers 2019-2020 Fusion/MKZ non-hybrids with cooling fans inoperative due to open fuses F59, F60, F63, causing engine overheat or lack of A/C cooling.

Last month, while transporting my brother to his arm surgery in Chapel Hill, NC, I observed unusual and audible shifting behavior when engaging the vehicle's sport mode. This mode is typically utilized for extended journeys on highways and interstates. Although the anomaly was brief, I did not initially consider it significant. Several weeks later, upon departing from my community college campus, I encountered a red light near Santa Fe Drive. The vehicle exhibited a hesitant and labored acceleration, eventually moving forward. This incident was particularly concerning given the high volume of traffic during that time of day. I subsequently stopped at a nearby 7-Eleven for fuel, suspecting a low fuel level might be the cause. No engine warning lights or mechanical indicators were illuminated, and the oil life was at 70% with appropriate oil levels. Fast forward to the last week of January. On Wednesday the 28th, I began to notice recurring shifting issues with the vehicle during a class break. Additionally, engaging reverse consistently resulted in a harsh shift. As I was leaving my neighborhood to return to class, the vehicle completely failed to engage gears or accelerate. At this point, both the wrench and check engine warning lights illuminated. Upon returning home, I utilized the code reader provided by my mother last Christmas, which displayed the code "P0772." This confirmed my prior research regarding potential issues with the EcoBoost engine. I am relieved that this mechanical failure did not occur amidst the heavy traffic typically found on 210 Murchison South , I-295, Bragg Blvd Fayetteville/Spring Lake and other routes heavily trafficked due to the military base. The high speeds on these roads could have led to a dangerous situation, potentially causing a rear-end accident or other involving other drivers who may be speeding or inattentive. I am grateful that I did not experience a stall in the middle of traffic, which could have compromised my safety.

The flexplate in my 2020 Ford Fusion SE (1.5L EcoBoost engine) failed at just over 53,000 miles. The car began making loud knocking and rattling noises while driving, and it vibrated heavily at idle and during acceleration. This posed a serious safety concern, as we feared the car could stall or break down while on the road with our toddler in the backseat. We took it to an independent, certified repair shop where they diagnosed a broken transmission flexplate, which required immediate replacement. The repair cost nearly $3,000, and the shop confirmed it was not caused by driver error or normal wear-and-tear. The failure was premature and mechanical in nature. The mechanic informed us that this specific engine and flexplate design have been recalled before in other Ford models using the same 1.5L EcoBoost engine and parts. They suggested we contact Ford, as this appeared to be a known defect that should be covered under goodwill or extended warranty. We followed their advice and reached out to Ford directly, but Ford refused to offer any assistance — even though they are aware of these ongoing flexplate failures across similar vehicles. After researching, I discovered Ford has had multiple flexplate and powertrain-related recalls in other 1.5L and 1.6L EcoBoost engines in previous model years. I also found many online complaints from other Ford owners experiencing the same flexplate failures, often at similar mileage. Yet, this issue has not been acknowledged or recalled for the 2020 Ford Fusion SE. This is clearly a design or manufacturing flaw that should be investigated by the federal safety agency. Flexplate failure puts lives at risk and results in major repair bills for consumers. Please investigate this ongoing issue before someone is seriously hurt.

My car is at 47,000 miles and i started To hear a loud noise . Turns out ford says it’s the Flywheel, transmission pump, and torque converter per ford technician who completed my inspection . No warning lights came on nor was there any alerts the ford app. My 2020 Ford Fusion with approximately 48,000 miles experienced a cracked flexplate. This caused severe engine vibration, knocking sounds, and ultimately loss of power while driving. A cracked flexplate can lead to sudden engine stalling or failure to accelerate, especially at highway speeds or during intersections. This puts the driver and passengers at serious risk of a crash due to unexpected loss of power or control. This issue happened without warning and is a known problem in vehicles with the 2.0L EcoBoost engine and 6F35 transmission. Ford is aware of the issue (Customer Satisfaction Program 22N12), but my VIN was not included, even though the symptoms and components match the defect. I am reporting this because it jeopardized my safety and others on the road, and I believe more vehicles should be covered under the existing CSP or a recall.

At first the check engine light was on and the car would not start. The dash would display all the lights and at one point it turned off while driving luckily I was going 20-30mph. Took it to the dealership and they said an Intake Valve had to be replaced and it was covered by the warranty. Next the engine light was on and a MAP censor had to be replaced which wasn’t covered. Once again the engine light and service light came on and the code is saying the same censor needs to be replaced. Each time it has effected how the car drives and is dangerous especially on the interstate because it will not go over 20mph. When the car is in reverse it will shake and turn off displaying auto start stop issue and place the car in park. It will then turn off. It is hit or miss on when the check engine light and maintenance light will come on and each time the symptoms are the same. No one has provided a solution. This has been on going for almost a year.
