Just recently, my car has thrown a check engine light. Cylinder 2 Misfire and Cylinder Misfire on start up. It doesn't happen every time, but sometimes when I start my car, it will have a really choppy idle for 10-15 seconds, then go to normal. Also, when hitting any boost, it sounds like a misfire/cutting out. I don't have any engine mods besides some drop in filter and the catback exhaust the car came with. I also just filled up my coolant last week to the maximum line, and it's already back to the minimum line. I'm almost 99% sure it's a head gasket, but I wanted to see what others think. I've read online that when this happens to people, the shop ends up coming back and telling them that they need a new engine. I also heard that it's such a common issue with these cars that there's a law suit against Ford for this faulty engine design. I have an appointment in a couple of days to get it checked out, but won't replacing the head gasket just result in the same thing later on eventually because of the poor design?

Unfortunately, I have to agree with your assessment. Do you have anyway of monitoring misfire counts? Can you pull the plugs and check for coolant contamination?

To my understanding it was years 2017-2019 that had the issue. I believe they fixed the issue 2020 and newer. In 2017-2019 Ford used this little groove between the cylinders to cool them but little surface area for the gasket so over time the coolant leaks past the gasket into the cylinders. I took have a 2018 so I know at some point I'm going to have this issue.

Before driving your car or even starting the motor, I recommend searching for coolant, look in your engine compartment, check the hoses, fittings, etc. Then do the same thing from underneath your car. Also check your motor oil for coolant.

If you have no way to look into the cylinders with the engine cold after sitting overnight with plugs removed by using a borescope camera, then you can verify if coolant is leaking into the #2 cylinder by having someone crank the engine over while you watch to see if any coolant gets blown out of cylinder #2 or any other cylinder while it's turning over. If there is coolant in a cylinder it will be very obvious when cranking over. You can make it even easier to be sure its coolant by placing some paper towels or even a piece of cardboard over the plug hole area when cranking over so it will soak up whatever gets blown out.

Sounds like classic blown gasket/head leak for sure.

My 2019 has coolant intrusion either from gasket/engine design flaw. But its under powertrain warranty so the engine is being replaced. But having to figure out if I am going to keep it or go up to a GT with a naturally aspirated.

I have a couple of questions and 1 comment:

1.> What year is the OP engine?
2.> What is different between the 2015-2016 and 2017 engine design? "My understanding it was years 2017-2019 that had the issue. "
3.> "I also heard that it's such a common issue with these cars that there's a law suit against Ford for this faulty engine design." (what are the sources of this information and please provide some links for others).

I believe that years 2015-2016 they had a overheating issue, so Ford engineers made the modification to the engine block to cover that issue. Basically it's putting a bandaid over the problem. We'll now they had engines blowing head gaskets in years 2017-2019. So they fixed the issue on 2020 and newer Ecoboost engines.

1. 2015

2. The engine is the same design from 2015-2019. Ford didn’t fix this issue until the 2020-2021 years.
3. here are some links. Website 1, Website 2, Video 1

I also have a 2015 with an October 2014 engine and have been following the forum chatter since 2015, so I know the 2015 is the same as the 2017 but since someone said it started in 2017 I thought I would ask for clarity.

All of the links you posted are the non 2.3 Ecoboost engines. I am not sure why 2.3 is not a part of the lawsuits but apparently there is some difference between the 2.3 and all the other 2.0 and smaller Ecoboost engines.

You watched the YouTube video from a Ford "repair specialist"!??
He mentions a 2017 design change on the 2.0TS Ecoboost motor. He goes on about how horrible the design is, and totally fails to explain the causes of how most head gaskets fail. Slams the manufacturer, without even commenting about his customer or the maintenance/repair history of said motor.
I like the guy, he's a top Ford technician! And puts out some good videos!! But he's not an Ecoboost Specialist or a Mechanical Engineer.

So it doesn't affect our motors then?

I am not aware of any overheating issue in 2.3 2015-2016 or any mod that Ford made to the block to cover that issue in 2017.

The design remained the same from 2015-2017.

yeah it’s not the exact same engine, but the YouTube video shows exactly what’s happening with the 2.3L as well. There’s tons of forum discussion about this exact issue. However, I’m just wondering how a head gasket is gonna fix it i it’s the engine design itself. It’s a temp fix rather than a permanent

The blown head gasket is not as prevalent in the 2.3 as it is in the 2.0,1.6,1.5 which is why the 2.3 is not a part of the lawsuit. Why and what the difference is I don't know but if the 2.3 had the same exact issue as the 2.0, 1.6,1.5 there would be a 2.3 in the lawsuit.

A lot of 2.3 engines were blown because of modifications which may have skewed the results enough to hide the head gasket failures, just a guess.

Also, there are many 2015 2.3 running around with no head gasket issues so this is not a defect that impacts every 2.3. Obviously is was not the best design which is why Ford changed it in 2020 but that does not mean it is a defect.

You’re totally right. But Idk what happened with mine because it’s completely stock besides a mbrp catback exhaust that was on the car when I bought it. if there’s any coolant in the cylinder, does that mean it needs a new engine? I have a full warranty for another two years but I’m really just curious because I don’t want the same issue to just reoccur later if they just fix the head gasket

All aluminum, direct injected, turbocharged, gasoline motors can have similar issues.
Knock/detonation, pre-ignition, excessive combustion heat and pressure can destroy any motor.
A new head gasket won't fix a poor running motor. That's why it's important to understand the cause of failure and correct it. If your going to burn cheap gas and ignore required maintenance. And continue to drive your car with a check engine light... your going to run the risk of engine failure.

As far as I know the only difference between our motors and that motor is the engine deck. Our motors have an open deck and that motor has a semi open deck. However the 2.0 (TS) cylinder head design is almost identical.
If ether motor is subject to detonation/knock, pre-ignition... You will have excessive combustion chamber heat and pressure, which can cause engine failure.

From all my research and parts diagram/number comparison with my local ford parts buddy there has been no update to the 2.3 block from 2019 up so to say they fixed the issue for 2020+ motors is just not true. I cannot say where the drawings the "makuloco" video come from since the current parts diagram's show the slit between the cylinders in the 2020+ blocks versus the cross drilled in the video. He does state the cross drilled block is for the 2.0L motor. It may be that the service manual diagrams used in the IDS/Oasis system that the techs use are in fact more up to date than the parts diagrams, but I cannot confirm this either. I do know the part number for the blocks is the same between 2019 and 2020+ so i do not believe there has been any revisions made.

If the head gasket is blown it also damages the open deck block sealing surfaces, so ford is recommending complete long block replacement versus just head gasket replacement. If just the head gasket is replaced with no block or head replacement, it's pretty much a sure bet it will fail again in short order.
