The vehicle in question has the coolant intrusion into cylinders 2 and 3 with rough idle on startup, p0300, p0302, p0303, and white smoke on startup. The vehicle now has 111339 miles on it and the out of pocket cost is more than what the vehicle blue books for in excellent condition. TSB 22-2134 speaks to all the issue and what the repair is. If this is a known issue then I feel this should be a vehicle recall by Ford due to the costly repair.

The contact owns a 2016 Ford Fusion. The contact stated that while driving the vehicle at an undisclosed speed, the vehicle felt as though it were going to shut off unexpectedly. The check engine warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the spark plugs needed to be replaced. The contact stated that after the spark plugs were replaced, one of the cylinders was misfiring. The spark plugs were replaced a second time, but the failure persisted. The vehicle was taken to another independent mechanic, where it was diagnosed that coolant intrusion into the engine had resulted in engine failure, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 130,000.

Engine reached high temperature on July 2 2016 the results of which required the replacement of the radiator. Apparently there is a class action regarding coolant system issues for my vehicles 2. 0l engine. The radiator failure may be the result of this issue. Engine overheated.

The vehicle experienced engine failure due to coolant intrusion into the cylinders on the engine. I've experienced engine misfires, rough running, check engine light, and I'm worried I'm going to see an eventual engine failure requiring engine replacement. The biggest issue is I've had total loss of power in my engine while on a public road more than once, before the check engine light ever came on. Its terrifying. It is dangerous. And Ford is aware it is dangerous. Ford issued customer satisfaction program 21n12 for certain affected vehicles due to this exact issue, but my vehicle is past the warranty so it's sol. The failure appears to be caused by a defect in the engine design allowing coolant to enter the combustion chamber. This is clearly a widespread defect as Ford had to create their limited warranty for it. This is something that needs to be recalled for all affected vehicles experiencing coolant intrusion and engine failure because it is not safe to be on the road.

Engine has coolant intrusionand is misfiring. Engine light came on. The coolant system found pressure to be dropping significantly. Removed spark plugs and inspected cylinder bores using borescope. Verified coolant is leaking into cylinder 2 and needed to replace the engine at ourisman Ford in manassas va. On July 11, 2026.

My 2019 Ford Fusion 2. 0l ecoboost (89,000 miles) experienced a sudden, severe engine malfunction due to a known manufacturing defect. The vehicle exhibited severe engine shuddering and a harsh cold-start misfire upon ignition. A diagnostic scan revealed trouble codes p0316 (misfire on startup), p0302 (cylinder 2 misfire), and p0304 (cylinder 4 misfire). A mechanic verified that these codes are the result of internal coolant intrusion into the engine cylinders, exactly as documented in Ford technical service bulletin TSB 19-2346. The structural design flaw in the engine block allows engine coolant to breach the cylinder head gasket area and pool inside the combustion chambers. This presents a critical safety hazard: the vehicle is at risk of sudden engine stalling while driving on public roads, a complete loss of motive power in traffic, and potential engine hydro-lock, which can cause catastrophic mechanical failure or an engine compartment fire. Ford is refusing to address this safety defect outside of warranty, leaving a hazardous vehicle on the road.

1. 5 liter ecoboost engine has a coolant intrusion problem into the cylinder to due a design flaw. Problem can cause several problems: loosing coolant and causing the engine to overheat, causing misfire in the cylinders, and can cause the engine to stallwhich has happened several time on me. The engine should be recalled as a safety concern for stalling, it has stalled on the i15 in utah several times.

Engine warning display came on with "cylinder over temperature" immediately after temperature gauge went from normal (slightly under 1/2 way) to "hot" immediately. Shut off engine - opened hood, coolant was noticed on passenger side just below coolant bottle. After waiting a little bit the tempature on the gauge hadn't dropped any & the radiator was cool to the touch. The day before washer fluid was added, while there the other levels were checked after sitting all night, the coolant was showing within the marked operating zone. Ended up calling for a tow truck.

Vehicle makes strange sounds from the fuel fill inlet and proceeds to stall shortly after while driving and most of the times fails to restart based on my own research it looks like purge valve issues my safety was put at risk by almost being rear ended multiple times from stalling on the expressway and red lights the problem has not been reproduced yet by the dealer it will be looked at on 07/15/26 the component has not been inspected yet the check engine light illuminated when the issue started.

Per mechanic, head gasket has failed due to known issue with 1. 5l ecoboost engines. Coolant is leaking into the engine. White smoke in the exhaust indicating coolant leak. Vehicle is currently availble for inspection upon request, but is destined to be sold. Driver safety as well as surrounding driver safety as risk should engine completely fail due to overheating while driving, potentially causing an accident. There is currently a class action lawsuit in the works for this issue as many other have had it. At this time vehicle has only been inspected by our local mechanic. There were no warning lamps, messages or other symptons prior ot the issue. When the issue stated, there was a "waterfall" sound in the engine compartment, which caused us to take the vehicle to the mechanic for diagnoses.

There is a known coolant intrusion into the engine that caused the engine to suddenly only go to a certain speed while on the freeway. It could have caused an accident on the freeway by suddenly going at such a slow speed. It is now found out that the problem is known by Ford and is part of a technical service bulletin, but no recall has been issued on this known problem. The TSB associated are 19-2139, 19-2375, 20-2100. By not making this a recall, Ford is knowingly putting lives at risk with potential sudden loss of speed in these engines. It is lucky this was late at night when not many cars were on the road.

While driving we noticed the engine light came on so we took it to our local mechanic. He said we were leaking coolant and it was too extensive fro him to fix so he suggested we put coolant in every few days. We researched the problem and found that these cars had a recall for this exact issue yet our VIN does not show it. We went to Ford dealership and they confirmed we need a new engine as they connected the ids. This vehicle was built at the hermosillo plant, has the same 1. 5l ecoboost engine, and has experienced the exact coolant intrusion failure that Ford recalled or extended coverage for on other vehicles. I am asking fotrd to reconsider my case because my vehicle has the identical defect despite my VIN not being included. My kids purchased this car for my wife and I in October 2025. I also included a VIN report based on my VIN number and if scroll to the bottom of that report maybe page 23 you will see the recall.

My torque converter went bad on my 2017 Ford Fusion, it's the same problem the other 2017 Ford Fusions had with their torque converter however my VIN is not on the recall.

My 2019 Ford Fusion has been diagnosed with the prominent ecoboost coolant intrusion defect requiring a newer 2020+ redesigned engine replacement. Ford is refusing to replace it or provide any discounts even though it's clearly a engineering defect. The vehicle has just 38,500 miles in 7 years of ownership. It has been regularly well maintained & not driven hard. This is inexcusable that Ford is not standing behind their product that has a plethora of well documented failures on these particular flawed design engines, namely the 2. 0l ecoboost that came in this vehicle.

I bought the 2015 Ford Fusion for my son as a graduation present as he headed off to college on his own. The car started misfiring upon cold start for about 5-10 seconds. Eventually the car started misfiring while driving. He frequently had to pull over on the side of the road while driving to make it to his destination. I had him take the car to a Ford dealership to be inspected. To my surprise, Ford parks of wesley chapel told me that the 2015 Ford Fusion 1. 5l ecoboost has a known issue with coolant leaking into the engine causing misfiring and eventually engine failure. They offered no assistance in fixing the problem. They told me the cost to replace the engine was over 13,000. 00.

I own a 2018 Ford Fusion ecoboost. I purchase it in 2021 with 11k miles on it.   today it has 34k miles and the engine block developed a crack.   through my research and my Ford dealer, I've discovered this issue is a known issue with the 1. 5 and 2. 5 litre engines in the Fusion.   my repair bill would be just about 7k.  .

The vehicle goes into limp mode without warning no matter the speed. Cylinder head temp sensor is not applicable on this 1. 6 engine model. The coolant over temp light illuminates with or without the car running. Coolant temperature sensor was replaced and indicates no faults to the obd. The coolant level and temperature is within spec.

See attached document for complaint.

I recently now am having to replace my engine a second time in 2 years due to a coolant intrusion problem.

The engine experienced a sudden failure that caused the vehicle to become completely inoperable. Prior to the failure, the vehicle exhibited intermittent hesitation, rough idling, and loss of power during acceleration. These symptoms began several weeks before the complete failure. No warning lamps were illuminated at first, but shortly before the breakdown, the vehicle displayed a check engine light and a “service engine soon” message. While driving, the vehicle abruptly lost power and became unsafe to operate. I was forced to pull over immediately, which created a safety risk to myself and other drivers due to the sudden deceleration and inability to maintain speed in traffic. The vehicle would not restart afterward. A repair facility has confirmed that the engine has suffered a major internal failure and requires replacement. The estimated cost of repair starts upwards of $5,000. The vehicle is currently non?drivable and remains available for inspection. The issue has been reproduced and confirmed by an independent service center. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. However, I have found multiple similar complaints from other owners reporting the same type of powertrain failure, suggesting a potential pattern or defect affecting safety.

Noticed that the coolant level kept going down with no apparent external leakage and was also getting a code for #2 cylinder mis-fire, after adding a total 1 gallon antifreeze I made an appointment at the local Ford dealer to see what is wrong. They diagnosed the issue to coolant leaking in to cylinder #2, there recommendation is to replace long block.

The car overheated due to coolant leaking. Found out vehicle has a coolant intrusion requiring a new engine now.

2019 Ford Fusion with 82,362 miles- just told engine coolant leaking into the cylinder walls and engine replacement is needed. Dealer said do not drive it! this is a known problem with this model and Ford has not recalled it. Ford is aware and have sent ts bulletins to their service departments but why not recall. My daughter’s safety has been at risk and now the value is worthless or an engine replacement. I cannot reach any leadership from Ford, just a call center which is telling me nothing can be done.

Coolant intrusion.

While driving at 75mph on the freeway, my 2020 Ford Fusion suffered a sudden, catastrophic ecoboost engine coolant failure. The vehicle instantly lost power and dropped to 35mph in active traffic, creating an extreme highway collision hazard. A mechanic has confirmed internal coolant intrusion in the engine block.

I own a 2015 Ford Fusion se. I bought it used when it only had 47,000 miles on it. Over the course of time since buying it in Dec 2022 until now, it has had low coolant that I have had to address but no visible leaks. Current mileage now is 87,100 and just recently the coolant was low again and the check engine light came on for dtc p0301 -cylinder 1 misfiring. It has had rough start ups, rough idle, decreased acceleration, and poor fuel efficiency. I have found the problem to be coolant intrusion – engine defect concern “coolant intrusion” is a known engine design defect in which coolant leaks into the cylinders, leading to internal damage, misfires, and eventual engine failure. After researching it I found that many other people have had the very same issue with no help from Ford. This should be a recall as this is an internal issue with the short block and something that should have been disclosed before purchasing this model/engine. The only repair that will fix the core of the issue is replacing the entire short block which costs thousands of dollars, way more than the cost of the entire vehicle at this point. Without fixing the issue, the engine will fail. Again, this should be something Ford should pay to repair, not any customer who came into this blind.

There is a problem with the purge valve causing my vehicle to rough idle and even cut off on me in the middle of traffic and even on the interstate. This issue is going on with a plethora of people with the same year make and model as me yet no recall has been issued. When I put gas in the car it won’t start for some time. If I’m not constantly pressing the accelerator the car will turn off by itself.

Coolant intrusion, problem.

Formal complaint – 2018 Ford Fusion 1. 5l ecoboost – engine block defect statement of issue:I am writing to report a premature engine failure on my 2018 Ford Fusion 1. 5l. The vehicle is exhibiting all symptoms of the well-documented "coolant intrusion" defect described in Ford technical service bulletin (TSB) 22-2222. Despite following all recommended maintenance intervals, the engine block has failed, allowing coolant to enter the combustion chamber. Observations:confirmed coolant loss with no external leakage found via pressure test. Significant white smoke and rough idle upon cold start. Desired resolution: since this is a known manufacturing defect involving the engine block's cooling channels—and not a result of wear and tear—I am requesting a "goodwill repair" for a long-block replacement. The current TSB denial based on [8 years] is unacceptable for a known catastrophic design flaw that compromises vehicle safety.

The contact owns a 2018 Ford Fusion. The contact stated that while driving approximately 55 mph on the highway, the vehicle experienced a sudden loss of power steering functionality while decelerating. The vehicle jerked, and a driver assistance system warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 157,017.

I am the owner of a 2017 Ford Fusion with 61,000 miles on the odometer. Please note that I have always taken good care of my car, having it serviced promptly when required. In recent weeks, I have had to replace my complete steering rack (cost $4,500) and two weeks later, my 1. 7-liter ecoboost engine due to a coolant leak into the number two cylinder at a cost of $6,700. Ford has known about both problems for years and they have resulted in both class action and small claims suits against the company. Regarding the engine, Ford issued customer satisfaction program 21n12, technical service bulletin TSB 22-2134 and customer satisfaction program 19b37 - supplement #4 to replace the car's engine short block. This covered cars for 7 years of service or 84,000 miles - with, as quoted in the Ford memo sent to dealers on June 9, 2022, "coverage automatically extended to subsequent owners," for presumably the life of the car. Since this is clearly a manufacturing error (as Ford admits in its June 9, 2022 memo to dealers) and not due to negligence on my part, I should be reimbursed for my expenses. The NHTSA should also open a recall case on this matter for owners like myself.
