Vehicle was sputtering while idle or in park. Engine light came on and when tested the diagnostic said -??cylinder 2 misfire-?? Noticed coolant level would decrease quite drastically in short matter of time, also causing vehicle to run hot or begin to over heat. It-??s not always possible (or safe) to pull over on the side of a busy freeway or wherever you are driving when this happens. After investigating, found that coolant was leaking into the cylinders. Being that this was a common issue in these specific eco boost engines I knew my engine block would need to be replaced. Car was at 40,000 miles when this started happening and still under warranty. Took car to the dealership explained the issue only for them to try to say there was nothing wrong with it after not even getting down into the engine. After much back and fourth they finally ordered a new engine block to replace the faulted original. Only took 6 months of the dealership having my car and dodging my calls and messages.

There is a coolant intrusion into the vehicle-??s engine, which has in turn created the need for a new engine entirely. This issue is known in 2017 Ford Fusions and vehicles have been recalled but only those made in certain manufacturing areas. The car is currently at the ford dealer for service and the dealership informed us this is a known issue and the engines have been recalled previously. After our own research it is clearly a known issue and should be recalled across the board. This vehicle is under 100,000 miles and inoperable, due to a manufacturer error. This needs to be made right and be an active recall for the 2017 ford fusion. There was no warning. I was driving one day at about 50 mph when the car lost all power to the engine and immediately slowed down on me. There is nothing safe about this and I would expect a company such as Ford, to make this right.

I drove through a strip mall shopping center on 8/13/2024, without warning, my 2017 Ford Fusion's engine shut down and I could not re-start the engine. There was no "Check Engine" light. The shutdown later proved to be caused by the failed Mas Air Flow (MAF) sensor, Ford Part #Part #: AFLS195 (8V2Z12B579A). My understanding is that the MAF sensor sends data to the Powertrain Control Module (PCM) to deliver the specific amount of fuel that-??s proportional to the airflow and without that information, the engine just stops. I read, the MAF sensor failure shutdown occurs in vehicles of many makes. I was in a shopping center when the engine shut down, leaving me stranded in the traffic, but minutes before I was in 45 MPH speed limit traffic on a main multi-lane thoroughfare. Had the engine shut down had occurred then. I may have been in a dangerous situation. In fact, an Auto Zone general information article on MAF failure stated, "These issues can create dangerous situations causing accidents and injury." There needs to be a fail safe that, when the sensor fails, like for example that causes the PCM to default value that does not cause a shutdown while activating the "check engine light."

while trying to pass another car, my car stalled and would not speed up, then the high temp light came on then it cut off. it has been diagnosed with coolant intrusion by Kirk Brothers which is where I bought it.I can't understand why ford will not do something about this. I guess someone will have to get killed before something gets done. I can't afford to get the car fixed and it's my only vehicle. I commute 40 miles every day to work and have no other option than to drive this unsafe car. I'm scared for my life but if I don't go to work, I cant provide for my family or pay for this car. my car has all the criteria i see on the ford's customer satisfaction page, why is it not on recall. And it was made at the Hermosillo, Mexico plant which has a recall but not on my car.. i don't understand why.

2017 Ford Fusion (87,000 miles): Check engine light was illuminated. Visited independent garage next day. approx $700 repairs did not fix the issue. Light came on a second time the following week.

While waiting for the appointment, the overheating warning message came on. Stopped at the dealer who topped off coolant. 3 days later with almost no driving in between, dealer diagnosed Coolant Leak, misfire cylinder #2 - similar to information available online - coolant almost empty. All vehicle maintenance and 4 previous recalls properly maintained for vehicle. No known recall notice related to the Ford Fusion Coolant Leak known issues.
