2017 FORD FUSION Engine Problems

Coolant intrusion into the engine causing my car to missfire going down the road. Car is sitting in my yard unfit to be driven. Dealership claims it had previously been remedied. The car has only been inspected by my mechanic. No prior warnings before the misfire occurred

Engine failed. Lost all compression. Evidently this is a known problem with this engine where the head, head gasket and block fail between cylinders.

2017 fusion 1.5 ecoboost.(purchased at 128k) 148k miles- 1 time white smoke at start up no check engine light. All of a sudden while driving started to drive rough. Towed too mechanic, determined cylinder #2 has coolant intrusion. Conducted the TSB. For this defect. All symptoms confirmed for the coolant intrusion. Got Quoted $10k for engine replacement. Vehicle has been parked in driveway since 10/24/25 too expensive too repair for a defective problem from ford.

My Ford Fusion has the 1.5L ecoboost engine. This engine has engineering issues that are known to Ford. My vehicle started producing white smoke from the exhaust and sluggish performance. At approximately 105,000 miles my vehicle went into limp mode due to a cracked head gasket. This was due to coolant intruding into the cylinders. Ford did a short block engine replacement and reprogrammed the PCM to try to fix the issue. At approximately 220,000 miles the vehicle started producing the same symptoms described earlier and the vehicle now requires a complete engine replacement. Ford refuses to fix this for me, even though it is well documented that this engine has engineering issues. These engines should last longer than 105,000 miles.

Coolant leaking into cylinder, causing sudden rough driving, engine overheating warnings that don’t match temperature readings and distract driving.

Vehicle is experiencing coolant intrusion from a crack in the engine block 3rd cylinder which is a known issue by Ford for my particular vehicle year (2017). Ford has issued a TSB/Recall for model years 2017-2019, I believe this issue should qualify for manufacturer recall as this is known issue.

Ford Fusion 1.5L Ecoboost engines are known to have a fault short block that causes coolant intrusion. This defect does not trigger a check engine light, so there is no way for a driver to identify the problem until it's too late. Ford issued a Technical Safety Bulletin informing mechanics of this issue but customers were not given an option to repair it. A Customer Satisfaction Program (CSP) was initiated to replace some VIN models short blocks, but not all. Other Ford 1.5L Ecoboost engines are having this issue and were not properly informed or given the option to repair through the CSP and are driving cars that can have total engine failure without proper notification. I have taken my Ford Fusion in for all the safety recalls and was never informed of this issue. I was not part of the CSP that aimed to repair the defect because my...

This Fusion has the same coolant leak as described in Customer Satisfaction Program 21N12.

Recommended by dealer service CS replace long block assembly Using bore scope found coolant leaking into cylinder referred to tsb22-2229 long block recommended. Cost originally was $7923.77. After service manager was talked to price went to$7016.27. Install to be completed by 11/20/2025. Upset but what can I do. Car has 47183. 2017 Ford Fusion

Vehicles Engine has been affected due to a know manufacturing flaw with design that caused coolant to leak into the cylinder walls of the engine block causing a rough idle, white smoke out of the exhaust and cylinder 2 misfire.

Technical Safety Bulletin 19-2346; coolant infiltrating cylinder #2. Quoted $8350 for long block repair.

I was experiencing engine vibration while driving and lack of power when I pressed gas pedal. I took it to an independent garage first, and then to the dealer. Both told me there was coolant and water in the cylinders, and the dealer told me I needed a total engine replacement consisting of the long block and the head gasket. And it was going to cost me $14,000. my car only has 44,000 miles on it and Ford told me there was nothing they could do about it even though it was a known issue dating back several years.

2 separate dealerships made me pay to replace faulty tires when the new ones blew out within less than a month of purchase. They also pocketed the mail in rebates I was promised for buying new sets of tires from their locations. I started taking my car to an independent garage for regular maintenance. My traction control light has been on since shortly after I bought the car in 2018 but I never imagined I'd be spending my entire savings on repairs immediately after the useless warranty expired. First it was a cracked flex plate which I'm lucky happened when I was driving on a side road as opposed to the interstate. I was going roughly 55mph when I lost my ability to steer, accelerate, or even cut power to the ignition. My car has been towed 4 times with total cost of almost 10K and it still isn't fixed....

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.

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...

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...

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...

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.

Engine is experiencing the all too common coolant intrusion.

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...

While driving the car, the engine indicator kept blinking then the car kept shaking. The Ford Service did inspection and found that there has been a coolant leak to Engine Oil which caused Engine Failure due to cylinder break.

Engine is losing coolant into the cylinders which causes car to overheat. When this happens car shakes and runs rough. When this occurs while driving down the road, thick white smoke comes from the exhaust blinding the cars behind us. If car dies, you lose power steering and brakes become very difficult to push. We had a repair shop check it out and coolant is leaking on top of the piston and exiting through the exhaust. The engine light comes on just before car begins to act up. According to our mechanic, it appears the engine block has a design flaw and Ford has issued a Technical Service Bulletin explaining the problem. Attached a picture of when it just begins to smoke. After a few seconds it fills the entire shop.

Coolant leak in the 3# cylinder mechanic said I need a new engine

Check engine light came on at around 80,000 miles after 30 min drive. Next day would not start. Jumped it and drove to autozone. Autozones check engine reader stated spark plugs. Drove it to local ford dealership where test came back the third cylinder misfiring because coolant is low and leaking into the engine. Quick google search states many 2013-2018 fusions have a recall for this issue however my specific vin is not included. Dealership never mentioned other fusions being recalled for this. Could have started an engine fire or lost control.

Noticed difficulty starting the vehicle and smoke coming out of the exhaust and the check engine light came on with code PO302. Found this was associated with coolant leaking into the engine which caused the coolant level to decrease and had to add coolant to prevent the car from over heating. These leaking fluids could have leaked onto exhaust parts causing the smoke and possibly could have started a fire in the vehicle. I took the vehicle to Rodeo Ford in Goodyear Az. and they confirmed the code displayed and smoke coming from the exhaust and had to add more coolant right away. They confirmed coolant was leaking into the engine and checked for the recall and said my vehicle was not listed as part of the recall even though other 2017 Ford Fusions were part of the recall. They replaced the engine costing me $10,039.35 and said that the...

My Fusion is a 2017 and in 2015 Ford reported a problem with the Eco-Boost engines. The issues is there is a flaw in the production of the engine that could cause a crack in the cylinder and allow coolant to enter the chamber and once that happens the engine fails. Ford did offer a customary recall for the engine, but it was limited on miles and time. I was never informed of the customary recall. My engine has a small crack that has leaked a small amount of coolant into the cylinder. The car still functions. My concern is that if the engine fails while it is being driven, that the engine will seize and the car will stop, and an accident could occur. Since I was sold a car with the defective engine, and it was not disclosed to me, I want ford to replace the engine, since...

Coolant leaking into cylinder causing engine problems.

The temp gauge suddenly jumped up and alert said coolant was low. Driving on freeway, car shut down before I could get into a shoulder. Big rigs swerving around me, could have been killed. No leaks under car. Cap off the coolant reservoir and the coolant level bubbles up back to normal. After that, even driving one mile makes the temp gauge jump up and drop down erratically. Quoted more thank $8,000 to repair because it requires a new engine? Ford dealership said this is very common issue for Ford Fusions, that it is a design flaw and many of their clients have had similar safety scares.
