ENGINE
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.
NHTSA complaint #11751983 — an unverified report by a vehicle owner.
ENGINE
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.

ENGINE
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
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.

ENGINE
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.

NHTSA complaint #11743221 — an unverified report by a vehicle owner.
ENGINE
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.

ENGINE
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.

ENGINE
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.

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
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.

ENGINE
According to Auto Zone, after being placed on scanner, the power train system (P0456) has a evaporative emissions system leak (very small leak) diagnosed at 76,919miles. Ford dealership says they cannot find a problem. When I put gas in the car I have to sit and wait at least 10 minutes before my car will start again. It takes a couple of tries and much hesitation, but it will start. Once you get started it has difficulty accelerating or may slow down on its own. Again, Ford dealership reports they can't seem to find a problem. When I told them the problem, they came up with a price to charge me to fix something they could not find. Ridiculous!! My ford app clearly states check engine problem detected, but nooooo they cannot find anything wrong. Two different dealerships. Thank God I keep my paperwork because others are complaining of the same thing. They have to put the pen to the paper or we will never get a recall.

ENGINE
Check engine light was on and off intermittently for a few months starting in march of 2025. No immediate problem then, vehicle had 89 90k miles. In August. The vehicles coolant was leaking into the engine . Rendering a misfire in the cylinder and blowing the head gasket after mechanical diagnosis but not checked immediately due to symptoms not occurring till after a few weeks in August.Car not once over heated but then would not start. The car would then not go past a 40 mph without the transmission pushing very hard. After 3rd party mechanic diagnosis, I looked into potential recall on Fords website and in fact there was one but I was never notified of. So I contacted ford . The said yes, your car is under warranty, however after taking it in, they refused to repair the damages since the problem occurred 10k miles passed the mileage listed on the warranty for the repair. The car is unsafe and not drivable and the issue, which they knew would occur, did not happen till 10k miles passed Fords set parameters in which even if I took it in at that timeframe listed, the problem was not noticeable to be fixed. Very unsafe and unfair to the consumer.

ENGINE
Coolant is intruding into the engine, with no sign of a leak. There was a TSB 22-2229 issued that my car falls under, but ford claims they are not at fault to pay for it. This was a manufacturing error, and was at no fault of my own. My car has less than 60k miles on it. A check engine light came on for cylinder 3 misfire. There was no warning signs that an engine failure was occurring. The car is not driveable as it could overheat at any moment.

ENGINE
The vehicle is having issues with not starting, white smoke coming from exhaust, multiple misfire issues, can not accelerate as car lags out in power. I had a mechanic do some diagnostic testing on it and he confirmed coolant is leaking down into the motor and the engine block is cracked. It currently is not drivable. Engine light started to come on and said it was the coil packs misfiring we changed them and it did not fix the issue. Put a brand new battery in as well and still won't start often. I have reported this to a law firm handling the case against Ford for this known issue. I have kids and do not feel safe putting them in this car as it is unreliable that could cause us serious injury.
