What stands out
Powertrain accounts for 36% of every owner complaint on file for this vehicle — the dominant problem area across 8 categories tracked.
Owners have filed 62 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: A 2020 Ford Fusion powertrain can fail with cracked flexplates (40k–123k miles), transmission problems, and shifter issues often appearing without warning lights. Ford's customer satisfaction program covers only specific engine variants, leaving many owners with $1,700–$3,000+ repair bills and no recourse.
Owners consistently report cracked or fractured flexplates as the dominant powertrain issue in the 2020 Ford Fusion, typically between 40,000 and 95,000 miles. The flexplate failure starts as a loud rattle or knocking from the engine compartment or transmission bell-housing, often with no warning lights initially. The noise worsens over time, and some owners describe severe vibration at idle and under acceleration. A few owners lost power completely while driving and pulled to the shoulder safely; others report the vehicle simply would not start after the noise appeared.
Transmission shifter issues come second: the cable bushing detaches or wears, causing the shifter to move into park on its own while driving, trapping the vehicle. These failures occur across the mileage range and sometimes trigger a WRENCH light, but many owners see no warning at all.
Transmission fluid leaks and full transmission failures follow closely, with owners describing slipping gears, harsh shifts, and whining sounds. Several owners had the transmission rebuilt multiple times within the first year of ownership at escalating cost.
A smaller group reports engine stalling mid-drive—total power loss while cruising or at a stop—alongside flexplate cracks or transmission issues.
Water pump leaks, alternator belt shredding, coolant intrusion into cylinders, and misfire codes appear in isolated complaints.
Ford's Customer Satisfaction Program 22N12 addresses flexplate failures but only for vehicles equipped with the 2.0L EcoBoost and 6F35 transmission; owners with 1.5L engines are routinely excluded despite identical failure symptoms. Goodwill repair requests and warranty extensions are commonly denied.

My Ford started making a loud noise whenever the accelerator wasn't being pressed, after taking it to the mechanic, he said it is the cracked flex plate. After some light research, it was aparent that this is an issue that Ford's cars have, and ford has tried to make it better by offering free fixes. I contacted the local ford dealer and since the car has 90,000 miles, it would have been covered.…
Car shifts into 1st gear when traveling at higher speeds (45+mph), causing a significant jerk and almost causing a rear end collision to myself. Car also loses power and jerks significantly hardwhen shifting to reverse and drive from Park. Afraid to travel over 45mph due to the downshifting.
The touchscreen display is not working. It turned completely black. I cannot change the radio station. I shut off my car and turned it back on and it is still not working had to hard reset the system car also shifts hard in and out of park and reverse, makes a clunking sound and shifts hard in first and second
