2019 Ford Fusion

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.

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.

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.

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.

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.

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.
