2020 FORD FUSION Fuelpropulsion System Problems

"The incident occurred immediately after shifting the vehicle into reverse and starting to move. The engine suddenly shut down with a 'System Performance' alert, and cooling fans engaged at maximum speed. Moments later, a thermal runaway event began in the high-voltage Li-ion battery pack, leading to a catastrophic fire. This is directly related to Recall 23V440 / 23S33 (BECM failure). The fire was extinguished by the local fire department in Telavi, Georgia (Country)."

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...

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. However, since it doesn't have a clean title, I was declined this service free of charge. I don't agree with this decision since I've been driving this car for over a year since it was purchased off IAA auction, and this issue was made clear only yesterday, but this issue is prevalent in cars like mine.The damage to my car specifically was to the back, and only affected the rear bumper and trunk. Therefore I don't think...

Check engine light keeps coming on saying evap emissions. Have replaced purge valve, gas tank inlet and solenoid. This is the 6th time for check engine light

Previously reported as a fuel pump issue, incorrect. The mechanic was incorrect. The fuel injectors failed releasing fuel into the engine and the entire system. High risk of fire.

Fuel pump failure. Vehicle is emitting gas from the exhaust system in the back. Not processing fuel as it should. High safety risk.

My 2020 Ford Fusion has experienced three separate flexplate failures, as well as transmission issues following the most recent repair. Failure #1: Occurred before I owned the vehicle (confirmed later in the vehicle’s history). The flexplate was replaced by a prior owner in 2022. Failure #2: [8/2023] – While I owned the vehicle, a loud rattling noise came from the engine area. My vehicle was towed to Foothill Ford, where it was purchased, and they replaced the flexplate. No power loss occurred. Failure #3: [5/2025] – The same rattling sound returned. I drove it to Green Ford, who confirmed the flexplate needed to be replaced, and they replaced it. No power loss occurred, but the noise was severe. After the third flexplate replacement, the transmission began slipping during acceleration. This issue did not exist before the repair, and Green Ford had told me the transmission was fine before they replaced...

After every fuel up on the vehicle since I bought it in October 2022 car was sluggish to start, it proceeded to get worse as weeks went by and car refused to turn on until multiple attempts. Days later as I was driving and came to a stop light the car was struggling to stay on. The check engine light finally turned on after a few months of struggling with being able to turn vehicle on after fill up. Upon taking it to the Ford dealership to inspect code P0496 AND P0456 were found. Upon further inspection I was quoted to need VMV and charcoal canister with reprograming to VMV totaling 1500 worth of repairs. After two days of waiting dealership advised that parts, primary charcoal canister are in back order as "this is a common problem with these cars". Telling me that there is no way of knowing when...
