2018 Ford Fusion: sudden loss of power

Filed Oct 5, 2026 · Engine · FL

My 2018 Ford Fusion suffered a sudden and complete engine failure caused by internal coolant intrusion — coolant leaking into the cylinders and destroying the engine. Pep Boys diagnosed that the failure developed internally over time and could not have been avoided by the owner. This is a known Ford factory defect in the 2.0L EcoBoost engine, documented in Ford's own publications (SSM 47204, SSM 47462, TSB 19-2346, TSB 22-2229), all of which cover the 2018 Fusion. The root cause is Ford's open-deck engine-block design, which allows coolant intrusion and cracking between cylinders. Ford corrected the design in 2019 production. A federal class action (Nelson et al. v. Ford, E.D. California) and the federal safety agency defect petition DP26008 concern this same defect. The sudden loss of engine power created an unsafe driving condition. My warranty claim was denied based on a 'blown head gasket' finding, which is the symptom of the factory defect, not the cause.

Capital Ford of Wilmington diagnosed my vehicle with coolant intrusion into cylinder 2, accompanied by diagnostic trouble codes P0302 and P0316, after check engine light came on. I have been advised that the vehicle requires a complete engine replacement, with an estimated cost of $13,180.89. The vehicle has experienced sputtering and hesitation, creating concern that it could lose power or stall. These symptoms are concerning. After researching this issue, I have learned that coolant intrusion is a documented problem associated with certain Ford vehicles equipped with the 1.5L EcoBoost engine produced during the 2017–2019 period. Ford has addressed this issue through Technical Service Bulletins and Customer Satisfaction Program 21N12. I contacted Ford and was told that my VIN is not covered under the Customer Satisfaction Program. When asked why mine was not covered but other were , Ford stated that even if it is the same issue that is being recalled if my VIN is not flagged it will not be covered for any recall or assistance.I called Ford when I first purchase vehicle and asked about this recall and was told if I didn't have anything wrong with my car and no engine lights that my car was fine and to bring it in if I have any issues.

My 2018 Ford Fusion Titanium FWD (VIN: [XXX]) suffered a catastrophic engine failure while driving, causing sudden vehicle overheating, severe engine misfires, and a dangerous loss of power on the roadway.A certified Ford dealership inspection (Invoice #XXX) confirmed that the vehicle has a textbook manufacturing flaw known as EcoBoost coolant intrusion. A pressure test showed an immediate 5 PSI drop within 10 minutes, and a borescope confirmed that engine coolant is actively leaking across the block interface and pooling directly inside the engine cylinders (cylinders 2 and 3).This is a known, widespread structural engineering defect in Ford's block casting that creates a severe, sudden safety hazard by causing vehicle stalling and clouding exhaust smoke while operating at highway speeds. The vehicle is now entirely unsafe to drive and requires a full engine block replacement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 1.5L EcoBoost engine experienced coolant intrusion into the cylinders, a known and documented defect associated with this engine family across multiple Ford model years. Prior to the failure, the vehicle displayed symptoms consistent with internal coolant loss, including white exhaust smoke, coolant level dropping without visible external leaks, and rough running. No external coolant leak was ever identified. The vehicle was subsequently diagnosed by an independent service center, which confirmed coolant intrusion into the engine internals consistent with a head gasket or coolant jacket failure. The component is available for inspection upon request. The failure rendered the vehicle completely undriveable. The vehicle has been out of service for approximately 12 months and has not been driven since the failure occurred. The repair was quoted at approximately $12,000 for a full engine replacement, exceeding the current market value of the vehicle. Safety was put at risk due to sudden loss of engine performance and drivability while the vehicle was in use on public roads. Coolant intrusion can cause hydrolock, catastrophic engine seizure, and sudden loss of power, all of which create risk of collision, particularly at highway speeds. This failure is consistent with a well-documented defect in the 1.5L EcoBoost engine design, which has been the subject of technical service bulletins and consumer complaints regarding coolant entering the combustion chamber. The failure occurred with no prior accident, overheating event, or owner-caused damage.

I was driving the vehicle on the freeway when the check engine light appeared and after a few seconds the cars engine suddenly shut off. There was a loss of power steering from the lack of engine power which made it difficult for me to steer and a sudden loss of speed which made several vehicles take evasive maneuvers to avoid having an accident with my car as I merged onto the shoulder of the freeway. After getting the car home I checked the vehicles trouble codes which appeared as P0301 cylinder 1 misfire and P0302 cylinder misfire and P0300 general misfires. I noticed a lack of coolant which I refilled and started the vehicle again to see if and how it would run. The car started but ran very rough at first and white smoke started billowing out of the exhaust. After a couple of minutes I decided to drive just down the street to my local Ford service center. They called me yesterday to tell me that the 2.0L 4 cylinder Ecoboost head gasket has failed and has allowed engine coolant to pour into the cylinder 1. The engine cylinder begins to misfire causing the engine to shake and emit white smoke from the exhaust as the coolant is burned off with the fuel. We are now seeing this safety issue and complaint with many vehicles that have the same or similar engine. They say the only remedy is to replace the long block engine with one that supposedly has a "fix" to the coolant delivery system within the engine block. Knowing what I know now, I would never have considered the purchase of this vehicle. The safety issue alone makes cars with these engines a danger to the owner and the public.

After I bought from personal owner feb. 3rd 2025 I drove 50 miles and overheated before I made it home . The check engine light came on it showed up as a bank 1 bank 3 misfire also camshaft position sensor so I replaced these things and it still was losing coolant oil is just fine. Every time I would drive it it would still overheat I would keep putting more antifreeze in to make it home. It started to misfire very badly still loosing coolant jerking when I would try to give it gas and some times would hardly move . I changed the thermostat still the same . So then I replaced the catalytic converter still nothing changed . Took it to a shop and he looked all over it couldn't find anywhere that the coolant could have been escaping he did find and replace the vvt solenoid. Worked for a very short period. So as the problems progressed and the car wouldn't even go 3 minutes without overheating and jerking losing almost all of its power my brother put a head tester on it and conducted the test to show it has a bad head so its not able to be driven to be checked by any dealership or anything also isn't under recall . Yes it is a safety hazard when I was able to drive it was losing power I couldn't gain speed even with a full pedal so took the risk of being hit from behind if a car had come up behind me .

At approximately 67,180 miles, a Ford dealership performed a multi-point inspection on my 2018 Ford Fusion SE with the 1.5L EcoBoost engine due to a check engine light on. The Ford dealership diagnosed the vehicle with a coolant intrusion into cylinder 2. The Ford dealership recommended the replacement of the short block and gasket kit, with an estimated repair cost of $7,465. This type of issue diagnosed for my vehicle is a known failure issue for 1.5L Ford EcoBoost engines documented in Customer Satisfaction Program 21N12, which covers coolant intrusion and engine damage in this engine type. Despite the Ford dealership diagnosis of my vehicle matching what is described in Customer Satisfaction Program 21N12, I was informed that my vehicle is not eligible. The Coolant intrusion into cylinder 2 is an issue that poses a safety risk due to engine misfires, stalling, overheating, and possible sudden loss of engine power while driving. In my case, my vehicle has become unreliable and unsafe for regular driving. A Ford dealership inspected the vehicle, confirmed and documented the issue, and the repair quote, diagnostic report and diagnostic payment receipt are available upon request. Ford has declined assistance despite the vehicle’s low mileage and clear alignment with known engine defects. I mailed a formal appeal letter to Ford Motor Company and I am filing a complaint with my state attorney general. This widespread issue affects customer safety, and vehicle safety standards and deserves further investigation, as many other Ford owners of vehicles with 1.5L EcoBoost engines have reported similar failures.

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.

My vehicle has had the check engine light come on intermittently. I took a look under the hood to see if I could spot any issues. The only issue seen was the coolant level was low. After refilling the coolant and a short time driving, perhaps 50-60 miles, the light went out. Then the light came back on a couple days later. Without making any changes the light went out a couple days later. It has done this several times and I thought it may be a faulty sensor or something. I have recently taken it to the dealership for a tune-up, emissions test, multipoint inspection and a transmission flush. I informed the service person that the check engine light will come on and go out and the only thing I have done to the vehicle was add coolant. He suggested the complimentary diagnostic to further identify the issue. During the diagnostic process the auto tech discovered that the coolant has been leaking into the number 2 cylinder. This is the reason for both the fluid loss and the check engine light. From my understanding this is a known issue with my vehicles engine type and has been for some time now. The only fix is to replace the engine. My overall issue is that the safety light (CEL) will say that there is an issue and then it goes away signifying the issue is resolved. The potential hazards of this could possibly lead to an individual unknowingly putting themselves and others at risk with an engine that is prepped for failure. An engine that could overheat, catch fire, throw a rod, or simply lose power in a very dangerous location. For example the freeway, a bridge with heavy traffic, or on train tracks…etc. I believe the risk of failure and potential to lose a life should be considered heavily against the cost of a recall. I don’t believe during the buying process it has ever been disclosed that this specific engine is prone to this problem. I know I would not have made my purchase knowing the engine would need to be replaced within the first 10 years of ownership.
