2018 Ford Fusion

The engine cooling system and engine block failed due to coolant intrusion into the engine cylinders. This issue has been diagnosed by an independent mechanic and is available for inspection upon request. Yes, the problem has been confirmed by an independent service center, which diagnosed coolant intrusion into the engine block, a known issue on this engine. The shop recommended full engine replacement and stated this is a common failure in this vehicle. Not yet by the manufacturer, police, or insurance. The issue has only been inspected by a certified independent mechanic. Yes, a check engine light appeared along with a coolant temperature warning message. The vehicle also began to idle roughly, produce heavy exhaust, and consume coolant. These symptoms began appearing shortly before diagnosis in June 2025. I own a 2018 Ford Fusion with a 2.0L EcoBoost engine. The vehicle recently began experiencing coolant loss, heavy exhaust, and check engine alerts. A certified mechanic confirmed that coolant has intruded into the engine block, causing internal misfires and risk of major engine failure. I was told this is a common and well-documented issue with this engine design, yet there has been no official recall from Ford despite similar problems affecting other models (referenced in Ford TSB 19-2208). The mechanic has recommended a full engine replacement with an estimated cost of $13,000. This is a serious safety concern, as the engine can overheat, stall, or seize while driving.

2018 fusion AWD Titanium, less than 70,000 miles, no warning, no reason. Driving 70mph on interstate when low coolant light comes on, check engine light comes on, car starts losing power and running rough, finally full stall in middle of freeway with catastrophic engine failure due to coolant leak and faulty design. Car was not low on any fluids as they were checked everyday before it was driven. This could have gotten me and my children killed and quite frankly I dont know how it didn't. I bought this car with 44k miles on it. Drove it less than 30k miles and had catastrophic engine failure. This was AFTER I had it in the shop several times for crank shaft position sensor, wouldn't start, and several other problems. The car was taken care of and in immaculate condition. Ford knew these engines would fail prematurely and continued to manufacture them and sell them.
