Overheating on other Fusion years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2020.
What this problem usually is

Across the vehicles on this site, about four in five of these complaints mention coolant, a leak or a puddle, and roughly two in five mention the temperature gauge or overheating.
What got replaced

“My 2017 Ford Fusion with 77,000 miles was running poorly. I noticed coolant reservoir was empty with no visible leaks. Took it to a Ford dealership and was told coolant was leaking into cylinders. I was told to fix the car they would have to replace the engine. Had I not noticed the coolant issue and the engine died while driving in highway traffic, my safety, as well as the safety of others would have been at risk.”
