Bought my car in 2019. Was unaware of coolant intrusion problem on my vehicle. Check engine light came on and mechanic just quoted me $13,000 to fix.
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 backup camera often freezes after I shift from reverse to drive. The screen turns blue and at time will have a live video of me driving showing what’s behind my car. Also my engine loses power and doesn’t accelerate as it should. There is a powertrain and censor error that shows due to the Che k engine light being on. I had the issue fixed once at a ford dealer however the issue was not resolved. It started up again 48 hours later.I have noticed that all other ford fusions have the same two issues and were included in the recalls but the 2019’s are not ? Please assist I have been trying to have these issues resolved for years with no success.
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.
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.
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.

The vehicle experienced engine failure due to coolant intrusion into the cylinders on a 1.5L EcoBoost engine. Symptoms included coolant loss, engine misfires, rough running, check engine light, and eventual engine failure requiring engine replacement. The problem has been confirmed by Ford and is consistent with the known coolant intrusion defect affecting many Ford 1.5L EcoBoost engines. Ford issued Customer Satisfaction Program 21N12 for certain affected vehicles due to this exact issue. The vehicle has approximately 76,000 miles and is under the mileage limit referenced in Ford’s program, but Ford denied full coverage and only offered partial financial assistance toward the repair. This issue creates a serious safety concern because the engine can lose power, misfire, overheat, or fail unexpectedly while driving. The failure appears to be caused by a defect in the engine design allowing coolant to enter the combustion chamber. I believe this is a widespread defect and should be covered for all affected vehicles experiencing coolant intrusion and engine failure.
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.
This vehicle is another of many that is suffering from coolant intrusion due to Fords faulty design. This 2.0 has 68 thousand miles and needs a new engine. This has been a known problem for this engine between 2013 and 2019. We were sold a new car that would be reliable for years, it’s not. Now we may be out upwards of $10,000.00 for a car we just paid off a year ago.
Coolant intrusion into cylinder #2 in my 2.0L Ecoboost engine. This gives a rough engine start and a misfire code for cylinder #2 on cold starts. After warmup, the engine code is not active and misfire goes away when the coolant is burnt and sent through the exhaust. This also caused the car to overheat as the coolant was dropping to a low level. There was no indication of the low coolant level until the overheating.

Coolant intrusion, motor destroyed by coolant due to faulty ford design
Dealer diagnosed coolant intrusion into cylinder 2, confirmed through a pressure test and borescope inspection. The dealer referenced TSB 19-2346.
Coolant leaking into cylinders on my 2019 Ford Fusion 1.5L EcoBoost—white smoke, rough idle, and wont start now. Ford's 21N12 program expired before I could get it fixed. Tons of owners report the same; it's a safety hazard.
2019 Ford Fusion equipped with the 1.5L EcoBoost engine has experienced overheating and misfire issues, linked coolant intrusion into the engine cylinders, which can lead to engine overheating and potential fire hazards. This is a KNOWN issue by Ford but they have not issued a recall, or even let me know in the 6 years that I have had the vehicle.
Coolant intrusion in engine per a diagnostic visit my local ford dealership on 1-30-26 , on my 2019 ford fusion apparently a known issue problem on the ford fusion
Engine catastrophicly over Revs when charging and plugged in phev plug.
Vehicle has a known Ford 2.0L EcoBoost coolant intrusion / head gasket defect per multiple complaints on different forums on recently googled searches. At approximately 126,000 miles, vehicle began losing coolant with no visible external leaks, producing white smoke on startup, rough idle/misfires, and check engine light. Vehicle also began overheating intermittently. Heating system stopped working, indicating coolant flow failure. Symptoms are consistent with internal coolant intrusion into cylinders due to head gasket failure, a widely reported defect in Ford EcoBoost engines. Issue presents a safety risk due to potential engine failure while driving, loss of power, and overheating. Vehicle requires major engine repair or replacement. This failure occurred despite regular maintenance and appears to be a premature engine defect, not wear and tear. I was recently at the dealership on December 8th with no other issues detected after they replaced a part on my car that failed that I had to pay for ( a P175B-00 ). This had nothing to do with what is going on currently, they ran tests at this dealership and did not detect anything as of December 8th. This was at a ford dealership. Tests were ran and inspected by manufacturer. Fast forward to a week ago I started having the above symptoms and this was diagnosed by family-friend auto mechanic. I have had multiple issues with this car. The transmission blew at 50 thousand miles, the sun roof leaked ( the seal for the sunroof was defective) into my prnd control shifter causing thousands of dollars in damage, a P175B-00, causing my car to not be able to park, causing chaos for weeks. I have only owned this car since December 2020. I still owe 7 thousand on this vehicle and I am at a complete loss. I really just want ford to take accountability for this make and model as it never fits the guidelines for recalls on anything. I want justice for myself and others with these multiple issues coming from ford cars.
My daughters’s 2019 ford fusion/4dr sdn/sel/fwd began to run hot and my son checked and notice low on coolant. He filled back up and vehicle ran with no problems. A day or so later noticed again and my husband checked again and realized again and low again and checked all and no apparant leak in lines or hoses but short drive again to check it began to overheat and check engine light came on and he read up and becoming aware of issue with this coolant leak into cylinder. He took to Sullivan Ford dealership and confirmed pressure test of coolant in cylinder # 1 and had to replace engine assembly. No offer by Ford to assist. Total cost 10,115.66 For know issue per faulty engine design that was risk for fire and safety issue.
Engine diagnosed with coolant intrusion problem into the engine cylinders. Car failed at 138k needing 12k repair from Ford dealership which is more than the value of the car. Transmission shifter bushing went out also in this car even though Ford did a recall for previous years of the model the issue has not been fixed.
10/2024 We noticed coolant was low. filled and kept watch. around 95,000 miles 6/2025 Just hit over 100,000 miles. engine misfire cylinder 3. brought it in, coolant was low, filled and replaced spark plug. 8/2025 engine misfire cylinder 3. brought it back in completed cleaning kit 8/2025 engine misfire cylinder 3. brought back in (2 weeks later). checked further and recommended a valve replace, and we needed to take it to a Ford dealership to replace 10/2025 brought into Ford dealership, coolant leaking into engine, need new engine. Ford will not cover. This is a safety issues as engine could cause fire, if coolant runs to low.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
