Previously, about 5-6 times the car experienced sputtering and then stalling shortly after a warm engine restart. After 2 tries, the car would continue running. No check engine. No codes stored. Final time (before a scheduled shop visit) it stalled on a busy 4-lane road at rush hour and would not restart. Wife managed to manuever into the middle turn lane. Would not restart. Car displayed (unhelpfully) to check the owners manual. Towed to Firestone who found bad spark plugs (in particular cylinder 3) showing coolant leakage. Firestone seemed to be aware of the systemic issues (said replacing plugs was not solving the root problem, but they don't do engine replacements. Estimated that the car might run correctly for maybe a year. Car stalled again 3 days later). Coolant level was low. My experience seems similar to many others (ie., 2013-19 engine coolant leak). Car at dealership.
The vehicle exhibited zero heat when driving to work. It was operating roughly with misfiring occurring. Significant exhaust smoke was emitted during this time, enough to obscure vision in the neighborhood. I brought the vehicle to a repair facility, where they diagnosed it as extremely low on coolant, the probable cause of the lack of heat. A malfunction indicator light signified a misfire per the repair facility. They performed a pressure test on the coolant system, which held overnight. Based on those diagnostic results, they opted to replace the spark plugs. This did not resolve the issues. I contacted the dealership to inquire about further repair options, but they indicated no assistance was available after reviewing the vehicle's VIN. The vehicle lost all power while driving on public roads, placing myself and others in jeopardy.
Engine Coolant Overheating Warning.keeps coming on. Engine coolant sensor 1 code amd Cylinders 1 and 2 misfiring codes on reader. Having to replace coolant every couple days. Afraid engine will be damaged and possibly catch fire.

2015 Fusion with 1.5t ecoboost only 57,700 miles on it. Engine is bad. Coolant got into Cylinder heads. Ford is calling it coolant intrusion. Never heard of repairing an engine with low miles. Repair quote is $7,500. I guess Ford extended powertrain warranty on 2017 and newer to 150k 10 years. While my 17 year old son has to figure out how to pay for this. Ford customer care had nothing to offer, not even cover parts. I guess there’s a class action lawsuit filed.

My wife's Ford Fusion started having issues in 2021. I was responding to check engine lights for things like spark plugs, O2 sensors, variable valve solenoids, etc. Eventually, as these check engine lights continued, in 2022 I took the car into the dealer to have it diagnosed. They told me that the whole engine needed to be rebuilt. They obviously see this problem frequently, as the woman I spoke to had lots of familiarity with the specific problem with these Ecoboost engines. She said that engine coolant will leak into the cylinder and cause lots of problems like the ones I was experiencing, and can even lead to a fire. The only solution they had was to rebuild and replace the cylinder head for $10,000. It was not long after the visit to the dealer that the car starting misfiring. It is very violent and the engine is running on only 3 cylinders most of the time. It is not safe to drive anymore.
The power steer system went out on my car with no warning , the catalytic converter is going out . This car have caused me more problems than a little. The dealership are full so you can’t get any recall done. This is a bad car and should be off the lots. I can’t get reimbursed for no work I put into this car because I didn’t take it to the dealership. This is unfair to me I work very hard for my money. This is about the third complaint I have sent and no one has responded. I WILL NEVER RECOMMEND FORDS.

Headlights do not work. I have replaced the low beams bulbs 3 times since purchasing my car over three years ago and each time the lights only work for a brief period of time them seem to short out unexpectedly, for no reason whatsoever. The high beams have been replaced multiple times as well. I purchased the fluorescent bulbs for better night vision. The lights were bright for a short period them dimmed and are only as bright as they should be if they were on low beam. This is some sort of an electrical issue or something to do with a manufacturer’s defect. Since I purchased my vehicle almost 4 years ago, there has been an ongoing issue with the transmission or alternator. The car “jumps out of gear” when putting the vehicle into park or when shifting the vehicle into drive from park. There is also a constant loud “humming/vibration” sound that clicks on and off continuously once the car is initially crunk up. The passenger door is coming off due to the loosening of bolts I assume but I’m not certain. Nothing has happened to cause this issue. The power outlets in the vehicle get extremely hot at times and cause phone cords to heat up. This has caused my phone to be destroyed! The rear view camera is now blurry with lines going through it. This is only happening when the car is put into reverse and rear view camera is in use. The Bluetooth and media in the vehicle gets stuck on “Sync Line In” & at times will not change to any other setting. This seems to be an electronic issue as well. There have been MANY recalls on my vehicle and I have taken it to the Ford dealership for repair each time however, none of these issue have been resolved . I am a single mother who work’s full time and is a full time student. This is my only form of transportation. I should not have to worry rather or not my car is safe for my children and I.

Short Block Replacement After Coolant Intrusion is affecting our model year 2015. Ford only placed a service recall on years 2017-2019 however the same issues are affecting the prior years and Ford is doing nothing to help consumers rectify this matter. Our 2015 Ford Fusion the 1.5L EcoBoost engine is exhibiting a low coolant level, white exhaust smoke and run in a rough condition with or without an illuminated malfunction. Our car dangerously broke down on road and Ford never sent us a letter of the known issue in their car.

There is coolant slowly leaking into cylinders. I am having to put antifreeze in reservoir every other month. I am afraid it will ruin engine or catch on fire.
The engine codes stated that cylinder 3 was misfiring, and all of the spark plugs were replaced. The check engine light went off for a few days and then came on with the same code. Then all of the coil packs were replaced. A few days later the engine light "coolant overheating" came on and the engine started running rough, the computer stated that it was shutting the car down to half power. There were visible signs of coolant sprayed all over the engine. After allowing the car to cool off for 2 hours the car continued to run rough and display coolant overheating.
