    We bought a 2018 Ford Edge Titanium in January 2023 from a KIA dealership in Clarksville Indiana, I wish I had researched the Ecoboost 2.0 engine failures first. If I had we would not have made this purchase. We have been getting Check Engine Light (CEL) lighting up frequently and the vehicle is now consuming coolant. It’s probably the beginning of the end for this motor. We can only hope the 3rd party extended warranty we also purchased will pay for the inevitable engine replacement. So far, we replaced the sparkplugs and one of the ignition coild on cylinder #4. My OBD-II indicates misfires on cylinder #4, code p0304 which is unusual because this issue usually involves cylinders #3 and #4.

    It is unconscionable that Ford has refused to do a recall for what is clearly a manufacturing defect. At the very least, Ford should do for Ecoboost 2.0 owners what they have done for Ecoboost 1.5 owners. I read a lady’s post online whose 1.5 engine was replaced and 95,000 miles. Apparently, people have to die from crashes and/or engine fires before they step up. If you are shopping for a car, avoid the Ecoboost 2.0 engine on all vehicles prior to 2021…


    First of all why would Ford have a recall because you have an engine misfire? The coil pack and sparkplug on cylinder 4 may not even be your issue since it was changed. A bad fuel injector can also cause a misfire and give you the same coil. As far as cool and consumption they only cause of this is a leak in the system. Faulty water pump or head gasket can be caused of the leak. At 95,000 miles this sounds like a common maintenance issue for any make or brand automobile. Have a competent Ford mechanic diagnose the issue properly.


    We have a Transit Connect with a 2.0L I4 engine not to be confused with the ecoboost 2.0L engine and we’ve gotten ( 1 ) misfire within the last 3 years and only because we opted to run full e85 fuels in the van. Although the van ran great the misfire came when we topped of the full tank with 10.00 USD. According to the owners manual, one shouldn’t top off the tank with less than 10.00 worth of fuel. Instead they should wait until at least half a tank to refuel. Mind you when one researches the specs of the van it shows that the 2.0L also listed as a flex van but doesn’t have the yellow fuel cap. Even taking the van to the dealership, they don’t have a clue as to if the engine is just gasoline or is a flex fuel vehicle. This is why we tried the eFuels and got the misfire. The code was cleared and we’ll avoid the eFuels. Not because they don’t work, but the fuel economy was terrible. That’s was a shame because the van ran like it was on a race track.


    1) Please re-read my original post. The 95,000 miles comment was in regard to a different owner with a different version engine.
    2) Pressure tested the cooling system. No leaks. Water pump has no leaks.
    3) You mentioned faulty head gasket which is interesting. After much research I found that this is a *known issue* with the Ecoboost 2.0 engine FOR THE FOLLOWING REASON. The engine has grooves scored between the cylinders in an ill conceived attempt to increase cooling. This allows coolant to degrade the head gasket and intrude into cylinder(s) leading to total engine failure. Ford addressed this issue with a redisign around 2020 or 2021. Just watch this YouTube video:

    Thanks for your input…


    UPDATE: A friend on a Facebook Group directed me to TSB 22-2229 (Technical Service Bulletin) You can get a copy on the National Highway Traffic Safety Administration. These bulletins are available now due to legisltive action; previously, they were only available to the automotive industry. This TSB addresses issues with the Ford Ecoboost 2.0 engine in the 2015 – 2018 Ford Edge and the 2017 – 2019 Fusion/MKZ/Escape and MKC vehicles equipped with the 2.0L Ecoboost engine.

    In the description of the issue the TSB refers to “low coolant level, white exhaust smoke and/or a runs rough condition with or without an illuminated malfunction indicator lamp (MIL) [aka, Check Engine Light or CEL]. Diagnostic trouble codes (DTCs) may include P0300, P0301 – P0304, P0316, P0217, P1285 and/or P1299 stored in the Powertrain Control Module (PCM). THIS MAY BE DUE TO COOLANT INTRUSION INTO THE CYLINDER. TO CORRECT THE CONDITION, FOLLOW THE SERVICE PROCEDURE TO REPLACE THE LONG BLOCK ENGINE ASSEMBLY. (Capitals added by me for emphasis)
