My Ford Fusion with the Ecoboost 2.0L 4-cyl engine has the design flaw that has the issue with a coolant to leak into the combustion chamber. Mine is in cylinder #2. The local dealer quoted $10K to replace the engine because it has the design flaw. I need this repaired because I need it to get to work. my 2016 fusion should also be covered by the recall.

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.

My coolants been leaking starting at around 110k miles and it seems like the 2016 ford fusions with 1.6L are know to have coolant intrusions due to a defect in engineering by Ford. This problem eventually leads to corroded head gaskets and can cause the engine to basically explode in the middle of nowhere which is a safety concern. The costs of repair is over 4k+ for a new engine or just to replace the head gasket for something Ford engineers should be liable for. Please look into this and you may even look at my car if you like.

I am reporting a potential safety and design issue related to my 2016 Ford Fusion Titanium with the 2.0L EcoBoost engine. The vehicle is experiencing coolant loss with no visible external leak, which is a documented issue under Ford TSB 19-2208. This condition can lead to sudden engine failure or hydrolock due to coolant entering the combustion chamber. A compression test revealed all cylinders at 155 psi, indicating the block has not yet failed — but the symptoms are known warning signs of the defect Ford acknowledged in its Customer Satisfaction Program 19N05, which does not include my VIN despite identical failure risk. Ford has refused to provide goodwill support under case [XXX], despite this being a well-known failure that has prompted engine replacements in other affected 2.0L EcoBoost models. Please document this case as part of your ongoing safety tracking. I believe this design flaw represents a serious long-term reliability and safety concern.
