I bought the 2015 ford fusion for my son as a graduation present as he headed off to college on his own. The car started misfiring upon cold start for about 5-10 seconds. Eventually the car started misfiring while driving. He frequently had to pull over on the side of the road while driving to make it to his destination. I had him take the car to a ford dealership to be inspected. To my surprise, Ford Parks of Wesley Chapel told me that the 2015 Ford Fusion 1.5L ecoboost has a known issue with coolant leaking into the engine causing misfiring and eventually engine failure. They offered no assistance in fixing the problem. They told me the cost to replace the engine was over 13,000.00.

I own a 2015 Ford Fusion SE. I bought it used when it only had 47,000 miles on it. Over the course of time since buying it in DEC 2022 until now, it has had low coolant that I have had to address but no visible leaks. Current mileage now is 87,100 and just recently the coolant was low again and the check engine light came on for DTC P0301 -Cylinder 1 misfiring. It has had rough start ups, rough idle, decreased acceleration, and poor fuel efficiency. I have found the problem to be Coolant Intrusion – Engine Defect Concern “Coolant intrusion” is a known engine design defect in which coolant leaks into the cylinders, leading to internal damage, misfires, and eventual engine failure. After researching it I found that many other people have had the very same issue with no help from Ford. This should be a recall as this is an internal issue with the short block and something that should have been disclosed before purchasing this model/engine. The only repair that will fix the core of the issue is replacing the entire short block which costs thousands of dollars, way more than the cost of the entire vehicle at this point. Without fixing the issue, the engine will fail. Again, this should be something Ford should pay to repair, not any customer who came into this blind.

My 2015 Ford fusion 1.5 L engine has had problems since 2022. I have been adding antifreeze, changed spark plugs many times, flushed my antifreeze and the vehicle overheats and has had to be towed twice changed out thermostat, spark plugs, coil pack, two times for misfiring coolant housing with no success. Called in a complaint to Ford Motor Co. and they are unwilling to help. They said they put out a bulletin however this does not fix the problem of needing a new engine. I am stuck making payments on a car I cannot drive. My mechanic says it needs a new engine. Never realizing there was a bulletin or a coolant intrusion problem with this engine.

Car began leaking coolant, overheating, smoking (white smoke) and misfiring on cylinder #3. Based on my research, this is an issue Ford knows about due to it being a defect in the design, yet I'm being told I have to pay to replace the engine. We replaced the spark plugs, coils, and nothing helped. We took it to a mechanic and were told we need an entire engine replacement and it won't be covered by Ford.

Coolant leaking into cylinder 2, misfire (P0302), overheating, and white smoke from exhaust. Mechanic diagnosed potential head gasket or coolant intrusion issue. Vehicle is out of warranty. This seems related to known issues on EcoBoost engines, including TSB 19-2208 for later models, but no recall exists for the 2015 model. Major safety concern and potential engine failure

We purchased a used car for my son to use in college. While driving on the hwy, the car started loosing power and just died on the side of the road. He was towed towed to a Ford dealer and was told he was leaking coolant into cylinder #4, which is a KNOWN PROBLEM AT FORD and an active recall for model years 2016-2018. Our 2015 has the identical failure mode and is not covered in the recall!! We were told $9000 to replace the engine block ... It only has 84,000 miles on it!!!!

The vehicle started to over heat because the vehicle is loosing antifreeze through the head/engine block wall. This is a 1.5L Ecoboost motor. I had the water pump and radiator lines replaced 2022 by Gorilla Techs, but that did not fix the issue. It has progressively gotten worse over the course of two years. Other Ford owners, they have had engine repairs covered. However, the recommend solution is to replace the engine with a long block engine. This repair is a result of poor engineering. A new engine from Ford is priced at $6,000 and does not include labor or other one time use parts and fluids.

My 2015 Ford Fusion with the 1.5L EcoBoost engine experienced a complete engine failure due to a coolant intrusion in cylinder 3, which is consistent with Ford TSB 20-2100. In December 2023, I brought the car to the dealership due to rough starting and a non-start issue. No coolant related codes were detected at the time. In May 2025, the vehicle began running roughly and showed codes PO316 and PO303. The dealership diagnosed low coolant and coolant intrusion into cylinder 3, with a rust and fouled spark plug. I believe this is a progressively safety-related engine defect that can lead to sudden loss of power and unsafe driving conditions.

In March of 2022 the engine failed on the vehicle. When I took it in for repairs, at the dealership where we purchased the car, I was told the engine needed to be replaced because coolant had leaked into the motor. I was told when the repairs were made I would not have this problem anymore. Three years later the same issue has occurred again and I took the vehicle back to the same dealer. This time they are trying to blame maintenance; saying there is sludge in the motor. The problem with this is the oil was recently changed (within 3500 miles) and the mechanic at the dealership did not identify any sludge or coolant in the oil. The dealership was told by the service engineer not to repair the motor. I looked on line and there reddit forums from people across the country having the same problem. What they are saying is the same thing the dealer told me. Ford is blame the customer claiming lack of maintenance. This is just a talking point because what everyone is being told is the same. Ford needs to be place under investigation. Law suits against Ford are documenting Ford knew the ecoboost engines had defects from the start and do not have a way to fix the design flaw and are refusing to make amends. Additionally these lawsuits are documenting the band aid repairs Ford is doing is simple to push the problem off and later not claim responsibility when the same malfunction occurs. The owners of Ford cars with ecoboost engine are out tens of thousands of dollars and have endure hardship inflicted by Ford that go beyond the vehicle damages. Ford should be placed under federal investigation and I believe it is possible criminal conduct may have occurred given the position Ford has taken in and its continued failure to make amends.
