2020 Ford Fusion: engine knocking or ticking

Filed Dec 19, 2025 · Engine, Fuel system · TN

In early October 2025, the vehicle was taken to an independent dealership service department for a routine oil change. Several weeks later, the vehicle appeared to be leaking fluid and began experiencing loud knocking/clacking noises, significant vibration, and drivability concerns, especially during acceleration. On October 10, 2025, while parked at a family member’s residence, the vehicle would not start. Due to safety concerns, the servicing dealership arranged for the vehicle to be towed for inspection. Technicians found a split transmission hose causing transmission fluid loss, which was repaired; however, the abnormal noises, vibration, and drivability issues persisted. Further inspection identified loud popping/clacking noises from the bell housing area. The technician physically inspected the flex plate and documented that the flex plate was cracked. The dealership advised that a cracked flex plate can worsen, cause severe vibration, damage related components, and lead to drivability issues or potential loss of propulsion. Because of the nature of the failure and symptoms, the vehicle was removed from regular use due to safety concerns. The vehicle was later taken to a manufacturer-authorized Ford dealership, which confirmed flex plate failure but stated the vehicle did not qualify for a customer satisfaction program due to engine variant. A goodwill/financial assistance request was submitted and denied. Technician diagnostic documentation from the manufacturer-authorized dealership was requested but not provided prior to filing this complaint. No crash or injury occurred; however, the failure created a risk of sudden inability to propel the vehicle while driving, including at highway speeds. The vehicle remains unrepaired and parked due to cost and safety concerns.

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.

I purchased a used 2020 Ford Fusion from Carmax n 2023 with about 56,800 miles. A week later was involved in a nor side impact accident on the back end driver side, insurance paid for a dinted door and there was no other issues with the vehicle according to SONS ford. In 2024 I was on the highway (going about 80 mph) when my engine light came on, no more than 3 minutes later all the lights in my car flickered and i lost power to my entire car almost causing me my life, roadside assistance and a mechanic who had thankfully pulled over explained that my alternator completely shredded my belt. I paid for both my alternator and belt to be replaced But most recently (2025) I continued to whirring and knocking noises for 3 days (no warning lights) , I took it to firestone who stated I needed a motor repair so I got it towed to the dealership. A Ford certified mechanic stated my Flex Plate was cracked and it begin breaking off and how I needed a new starter as well leaving the car inoperable. They confirmed this was very uncommon due to the car age and the miles on it (80,000 mi) I’ve also reviewed the complaints on the federal safety agency and it looks like a lot of 2020 ford fusions are having these issues but yet no recall.

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.
