Exhibited signs of a coolant leak followed by throwing a code about cylinder 4 misfiring. Took my car to the dealer who confirmed that there is coolant leaking into cylinder 4, and it is similar to other defects found in many 1.5 liter ecoboost engines from this model line. Was told that my VIN did not qualify for the recall that is only for the ecoboost 2.0 liter engines even though they have the same defect.

On April 25, 2024, my car broke down as I was driving. There were no warning lights leading up to it, and then all of a sudden, the check engine light started flashing, my temperature gauge spiked, and I was forced to pull over as the car barely responded to the gas pedal. When I got out, there was smoke coming out from under the hood, and just moving the car to get it towed better made the engine shudder and screech. At that time, the mechanic replaced the water pump, which appeared to solve that issue. But after that, between April and November 2024, my check engine light came on no less than 5 times. Each time, I took my car to the mechanic and they identified and fixed the code to the best of their abilities, but a few weeks later, the light would be back on again. They said the car might have an internal coolant leak and needed a new spark plug and ignition coil. Even after they replaced the spark plug and the ignition coil, I would also occasionally hear screeching sounds as I drove, or-- the longer this went on-- the car would shudder any time the engine was running. Finally, my mechanic told me that the internal coolant leak was something only the dealership could fix, so I took it to Ford, who evaluated the car and found an internal leak in cylinder 2. The only way to fix it would be to replace the entire engine, which I could not afford. The car has been sitting undriven ever since. If I'd been on the highway or driving at a faster speed when the engine suddenly cut out, I could've been in an accident. The only warning for the cylinder issue was the continuous check engine light and the shuddering of the engine, and the same issue was confirmed by an independent mechanic (AutoExpress in Doylestown and the Ford Dealership). There are numerous results on a Google search regarding Ford EcoBoost engine coolant intrusion which is the exact issue I'm having but Ford has not recalled the 2016 Fusion nor offered any solution to this dangerous manufacturing defect

severe coolant intrusion issue where coolant leaks into the cylinders, causing rough running, overheating, and potential engine failure. Very unsafe especially due to the fact the their were recalls on the 2017-2019 but not for 2016 models and ford refuses to replace the engine.ford reproduced a better block however my 2016 isn't covered. There signs of rough idling and a engine code for a failed coil . Replaced all coils and spark plugs just for the car to still ride rough with no warning signs. Ford knows themselves that there was a flaw in the making the recall for the 2017-2019(21N12) . This is a major issue considering several reviews or reddit consumers have encountered the exact issue at 100k miles and less. Even when I took my car to bill estes they only found a missfire due to coil. Nothing specified a coolant intrusion.

The 1.5l engine is having known issues with coolant intrusion into the engine under 100,000 miles. Many people are bringing up their issues staying ford is confirming the mass amount of engine issues with intrusion and quoting $6,000 for new engines. This is absurd because these vehicles should not have an engine known to fail at 100,000 because of leaking coolant into the cylinder. I started losing coolant at 90,000 miles and having to fill it back up.
