Similar situation. Ford Fusion 2016.
Kept taking it in for engine issues.
Thankfully my dealership cares and they replaced the engine.
Turns out the engines came out bad for that year from the factory. The entire line of engines manufactured around X time were bad. Took some diligent dealership personnel to get to the bottom of that. Still thankful to them that they cared enough to help. I'm loyal to the dealership/ people. Not the brand.
