My 2018 Ford Escape that I got under 3 years ago needs a new engine. It has the ecoboost engine. There should be a recall for this car because so many people are struggling with this. I know that there are others out there struggling like I am with a lot left to pay off their lease and not having the ability to buy another vehicle or afford a new engine. My first check engine light came on and was a cylinder 3 misfire. The spark plugs were all replaced. The engine light came back on after a week and it was a cylinder 2 misfire. The light came back on after a few days of getting it inspected/looked at. Took it back to the shop and I was told the engine must be replaced because leaking coolant getting into the engine causing many issues. Their ecoboost engines are faulty and they should be held accountable.

There is an Internal coolant leak inside of engine took it to a ford dealer they said it was not doing it when they checked it. This problem is getting worse blowing thick white smoke out of tail pipe and losing coolant rapidly. I looked this up it is a known problem /recall for this engine, make and model of vehicle. I have been trying to get this fixed for a while now and ford just gives me the run around. I had my mechanic test it and it came back as blowing combustion gas into the coolant system indicating blown head gasket or internal leak.

I want to report a coolant leak that is a known issue with this vehicle. Im dealing with misfires and uncertainties when driving.

- Humble, TX, USA

Engine must be replaced due to coolant intrusion into the cylinder head. I was not told about any ongoing issue from the car dealer when I purchased in July 2022. I bought and financed car in good condition with 91k miles for $15,500 (which was fair market value). I found out approx a year ago about ongoing issue, when I noticed excessive coolant loss. I was told engine replacement was the absolute only fix. I have added coolant weekly to keep from overheating. Approx 6 weeks ago; wouldn-??t crank in my driveway, so I had towed to a mechanic to find out it now needs the new engine. Two cylinders have compression under 30-35. I initially had no options other than to trade or sell a lemon or replace the engine. I still owe over $7500 on a vehicle that doesn-??t run. This is obviously a widespread issue and shameful that Ford will not assist in repair costs and isn-??t held accountable for lack of info or assistance in repairing a defective automobile. A Ford dealership I consulted, confirmed no assistance offered.

Engine overheating due to coolant loss into cylinder through internal leak. Engine and vehicle are available for inspection. Engine overheating due to coolant loss into cylinders can be a risk for vehicle fire. Overheating affected my engine longevity and function and caused my vehicle to stop in an unsafe location (i.e. the highway). This is a serious safety concern for my family since we also live in Arizona where we are highly susceptible to extreme heat. I took the Ford vehicle to a Ford dealer to inspect and they verified that the engine block was warped due to an internal leak of coolant into the engine cylinders through a known recall issue Ford Vehicle has been inspected by the Ford dealership by certified Ford mechanics. Overheating had no warning since internal coolant leaks are not detectable through external means. When car overheated, I took the vehicle to Ford for inspection.

There was a coolant intrusion into engine and mixing with oil causing check engine light to come on. There is a memo from Ford that if this happens the only repair would be to replace the engine motor assembly with all hardware (for the cost of $9, 467.88). The safety of myself and others was put at risk because the engine experienced sudden performance issues due to coolant mixing with the oil. These symptoms could have led to a complete engine failure, especially at highway speeds or in heavy traffic, which creates a serious risk of accidents. Additionally, the potential for internal engine damage raises the risk of a fire, as documented in similar cases involving EcoBoost engines. I was driving a vehicle that could unpredictably stall or become inoperable, putting both me and other drivers in dangerous situations. The Willowbrook Ford Dealer diagnosed the problem on 6/13/25 after running diagnostics. The engine light came on on 6/11/25.

At approximately 53000, our 2018 Ford Escape began experiencing engine misfires, rough idling, and visible white smoke from the exhaust. After inspection, the dealer confirmed that coolant was leaking into the combustion chamber due to a known design flaw in the 1.5L EcoBoost engine -?" a condition widely reported by other Escape and Fusion owners. This issue was previously covered under Ford-??s Customer Satisfaction Program (CSP 21N12), which extended short block replacement for this exact problem. However, Ford has denied coverage, citing that the vehicle is now just outside the 7-year eligibility window, despite the low mileage and the fact that this is a documented manufacturing defect, not normal wear and tear. Coolant intrusion into the engine is a critical safety risk, as it can cause sudden engine failure, stalling, and loss of power -?" all of which create dangerous driving conditions, especially at highway speeds. Thousands of owners are reporting identical issues online, and many have suffered catastrophic engine failure well before 100,000 miles. Request: I-??m submitting this complaint to formally document the safety concern and urge the NHTSA to investigate this widespread issue and consider a recall. The current extended warranty program is inadequate, as it leaves many consumers -?" like myself -?" with no recourse for a known, dangerous defect.

the check-engine light started coming on just over mile 100k, codes came back as a cylinder misfire. Due to faulty coolant supply systems, the coolant would be used up very quickly, which could cause the engine to overheat and become dead in the water, effectively endangering anyone driving it. The vehicle has had several repairs to the engine, all for the light to come on several times more.
