Engine has cylinders flooding with coolant due to the design of the EcoBoost engine
Coolant intrusion and requires short block replacement
I am a single mother raising my 6-year-old daughter on my own. This past year has been extremely difficult, as my car has been constantly in and out of repair shops. I have spent more than $8,000 in the last year and a half on unexpected repairs, many of them involving serious safety issues. I was never informed about the recall and never received any notice. This situation has caused me a lot of stress and hardship, and I am asking for guidance and support to help me through it.

When turned on airconditioner car shuddered engine light came on started blowing white smoke alot and blow buy engine oil in crank case
Coolant leak into the cylinders. Replaced the first engine for the same issue, this is the second engine.
Check engine light came on Took to dealer 2017 Ford Fusion 2.0 engine. Tech said code p0304 showed on the pcm. Did a scope on cylinder found coolant leaking cylinder Said he referred to tsb22-2229 and it showed replace long block That was May 22 2025. Price for parts and labor$7923.77. 82 years old fixed income Can not afford. Car still sitting in my driveway. Ford gave me a case # but said car was to old to do anything about it
Shift cable came off the transmission shifter bushing.
My vehicle had been experiencing overheating issues for several years. This would cause my car to go into limp mode making it dangerous for me and other cars around me to have to go around me. This issue is related to a manufacturing defect caused by the design of the motor cooling system. As a result of this defect I had to pay $8k+ to have this car repaired with a new engine. I am thankful no one was hurt or killed as a result of this defect. It could have caused my car to start on fire. Ford needs to take responsibility for this issue.
The engine has suffered a complete failure due to a known defect in the 1.5L EcoBoost. This issue was already repaired once under Ford Customer Satisfaction Program 19B37/21N12 (engine short block replacement) on 10/12/2020 at Stilwell Ford, before I owned the vehicle. Less than 5 years later, the exact same defect has occurred again. Details of Failure: •Vehicle began running rough with loss of power and abnormal engine noise. •A compression test performed by my repair shop shows: Cylinder 4 = 0 psi compression, with cylinder wall scoring and oil intrusion. •Shop diagnosis: engine requires complete replacement (~$7,000 repair). •Symptoms are identical to the coolant intrusion / cylinder failure defect covered by Ford’s prior CSP. •This is the second time this defect has occurred on the same vehicle. Safety Risk: •Vehicle misfires and shakes violently, making it unsafe to drive. •Sudden loss of power and potential stalling in traffic pose a serious risk of crash. •Drivers are given no warning before engine failure occurs. Manufacturer Response: •Ford acknowledges this defect under CSP 19B37/21N12 but refuses further coverage since it was “already repaired” once. •As a second owner, I never received notice of the defect. •The fact that the failure recurred shows Ford’s repair program did not fully resolve the defect. Request: I am reporting this as a repeat safety defect. The failure has occurred again after Ford’s supposed remedy. the federal safety agency should investigate whether Ford’s CSP repairs adequately resolve the defect, and whether additional recalls or coverage extensions are warranted.

2017 Ford Fusion got serviced at Ford dealership June 4, 2025. Service included, transmission flush, fuel induction service, oil change, oil filter change. About a month after service check engine light comes on upon starting the vehicle, but then goes out. A week later check engine light comes back on and would not start properly. Vehicle taken to independent mechanic and was told transmission fluid was low and also old. Vehicle taken to Ford dealership where service was done month prior. Ford dealership said cylinder misfire, coolant intrusion, and engine failure. Also transmission fluid was found to be low. Ford recommended new engine.
Vehicle is experiencing coolant intrusion from a crack in the engine block which is a known issue by Ford for my particular vehicle year (2017). Ford has issued a TSB/Recall for model years 2017-2019, but when I contacted Ford, I was told my car is not eligible/included in the recall because of the plant that the vehicle was manufactured at. I believe this issue should qualify for manufacturer recall as this is known issue.

My engine experienced coolant intrusion into cylinder #2, which caused misfiring and engine failure. This has been a known issue with this year model, but since I am just outside of the warranty mileage (69K) and my VIN doesn't have any recalls, I have been advised to purchase a replacement engine. I simply cannot afford to replace an engine in a car I am still paying a loan for. For this to be a known issue and not be recalled is a serious safety concern and has caused me to lose confidence in the manufacturer. I am currently trying to see what a shop near me would charge to replace it but I am not sure that I can afford the repair costs. I shouldn't be expected to need to replace an engine when the year model has known issues and I have taken care of any and all maintenance on the car to keep it running well. I expected to have this car for many more years, especially with the low mileage and how well I've cared for it.
The vehicle's engine is experiencing coolant intrusion. As such, when starting the car, white and sweet-smelling exhaust exits the exhaust pipe. Furthermore, the coolant reservoir continually runs low; however, we find no coolant on the driveway or apparently leaking from the car. That supports the mechanics assessment of a coolant intrusion. This issue, if left unaddressed, will cause the engine to run improperly, the spark plugs to become fouled, the engine to overheat, etc. I took the vehicle to a local certified mechanic. Although after looking at Ford's service bulletin, it became apparent that the vehicle is experiencing a similar issue to other 2017 models that were included in the recall. The mechanic listened to what we said and pulled up supporting documentation in the form of a Technical Service Bulletin. The check engine light just came up, within the past couple of days, well after the coolant intrusion was started. The disrepair seems to be a matter of timing. The subject has been driven quickly and cautiously.
What malfunctioned- Car did not give any notice that it was in engine failure for months other than under performing and upon taking it to the ford dealership was never helped with the problem they took money for an oil change and works package but failed to make sure my car was safe. My car was a safety hazard bc it gave zero warning that it was loosing power and when the engine did fail I knew something had been wrong for almost a year and felt it went ignored by Ford and was taken advantage of. The product has been confirmed by multiple mechanics that what causes it is the hose cracks and thus the engine coolant wrecks a working engine. Ford knows it’s a problem but isn’t acknowledging it and makes more money off of parts.

Manufactured dates for the 2.7L engine put only into the trim model Ford Fusion Sport (a rare trim) during 06/16 - 01/17 have been documented to have cylinder head issues resulting in long block issues. (Meaning a whole new engine is needed) the only way you got this issue fixed is if it was done in the first 3 years of 2017 or within 39k miles. But for those that didn’t get their vehicles in during that time frame are supposed to pay out of pocket for a defect ford knew to exist and have no issued a recall on these vehicles.

I purchased my 2017 Ford Fusion Titanium brand new with only 5 miles, from a dealership in Ky. My car recently started idling rough when I started it up. I took my car to a mechanic, after the check engine light came on. The code read misfire on cylinder 3, they replaced spark plugs and coils for $600, but only a few days later the check engine light came back on, still rough idling. I take my car to a 2nd mechanic $200, to find out that there is a “coolant intrusion” in the cylinders, indicating I would need a new engine. In disbelief, I take my car to a 3rd mechanic, $100. I have records from two different mechanic shops showing that there is a coolant intrusion in the engine, which is a "manufacturer defect". I called Ford's Corporate Office for help and apparently my VIN was not a part of any recall, although there are many recalls for the same issue, in the same year and model! There’s a recall on the car engine itself (per 3rd mechanic). Ford told me they couldn’t do anything about their manufacturer issue. Research initiated by the mechanic indicated that Ford Fusion cars with the same make and model, along with many other Ford models in the same year of 2017-2019 had the same issue of coolant intrusion into the cylinders and have been recalled. There are also active lawsuits over the same issue. It’s honestly unbelievable and disheartening that my car is not a part of the recall when it’s doing the exact SAME thing as others with the same year and model, which have already been recalled. I cannot afford to put a new engine in my car. It should have lasted a lot longer, and would have, if it weren't for a Ford manufacturer issue. I have all the documentation as needed, which states that I need a new engine and that the engine itself has already been recalled (however, the VIN shows no recall for the car). I will also be reporting this issue to the federal safety agency. Thank you for your time on this matter.
