I have a 2015 Ford Fusion ecoboost t back in 2019 took it to Ford for regular maintenance and they told me it had a recall for another engine (coolant intrusion) at that time I had no problem with my car so needless to say I was shocked . Now 2026 August 15 my car shuts down coolant temperature warning comes on , I pulled over had a mechanic look at it and he tells me the head gasket is no good coolant intrusion this is a safety issue and cars could catch on fire ?? called Ford they said nothing they can do . All I can say is shame on Ford they need to do the right thing and fix these safety issues.
The contact owns a 2015 Ford Fusion. The contact stated while starting the vehicle, the check engine warning light remained illuminated, and the vehicle failed to immediately start. The vehicle was taken to the local mechanic who diagnosed and determined there was coolant inside the cylinders and informed the contact that the engine long block needed to be replaced. The vehicle was not repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 100,000.
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.

The contact owns a 2015 Ford Fusion. The contact stated while driving 40 mph, the temperature gauge indicated that the engine was overheating, and the vehicle started losing motive power. The contact turned off the vehicle for three minutes and then immediately drove the vehicle to the local mechanic. The vehicle was taken to two independent mechanics. The first independent mechanic diagnosed the vehicle and determined that the head gasket had failed and needed to be replaced; however, the mechanic was unable to perform the repair. The vehicle was then towed to the second independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN associated with the failure. The contact was referred to the NHTSA hotline for assistance. The failure mileage was 144,000.
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.
After check engine light and the coolant fluid low light came on, I took it to a Ford dealership and was told that they found there was a coolant leak which caused the engine to fail and that the short engine block needed to be replaced and it would be 9000 dollars to repair. So we are now faced with paying for a repair that is double what the car is worth or get a new car. There was never a recall for the coolant leak even though Ford knows its a known issue.
I only have 85k miles on my 2015 Ford Fusion. One day the check engine light came on, my car started stalling, shaking, and making noise. I stopped the car and checked the engine- coolant was exhausted. Upon taking to get it checked- the head gasket and short block were blown/cracked. The coolant had leaked into the engine. This should not have happened on a car with this low of mileage. I did my research and this is a well known issue for Ford Fusions during this time range. I called Ford and they told me there is nothing that they could do.
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!!!!.

Coolant intrusion in cylinder 2 and 3.
The engine (1. 5l ecoboost) has suffered a failure due to coolant intrusion into cylinder 3, which has led to repeated engine misfires. Trouble codes p0303 (misfire cylinder 3) and p0316 (misfire on startup) were found. The vehicle is currently available for inspection, and a diagnosis was performed by two Ford-certified mechanics using a borescope, confirming the presence of coolant in the combustion chamber. The misfires cause rough running, hesitation, and potential stalling, especially during startup and acceleration. This creates dangerous situations in traffic, such as loss of power while merging or crossing intersections, increasing the risk of a collision. Both technicians concluded the engine has coolant intrusion and recommended a short block replacement as the only viable fix. I was quoted approximately $10,000 for the repair. The vehicle has been inspected by the manufacturer (Ford), but despite acknowledging this is a known issue with the 1. 5l ecoboost engine in various Ford models, they are unwilling to assist with covering the cost of the repair in my case. The check engine light initially came on intermittently and then became constant. Symptoms such as engine misfires, rough idling, and hard starts appeared around the same time, several weeks ago, and have progressively worsened since.
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.
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.

Unknown. La palanca DE cambios no funciona. No se pone en parking y cuando el carro se apaga no quiere prender.
Engine overheats to cause enough damage to loose all compression and power then fail to restart mid-drive even at highway speeds in passing lanes next to a semi tractor trailer. Had to have vehicle towed in after walking ½ mile to gain enough service to call for help/tow truck. Engine then requires replacement to run.
I own a 2015 Ford Fusion with over 160,000 miles on it. I noticed a substantial loss of coolant inside the car and decided to take it to a Ford dealership in October. I was told that my coolant was internally leaking into the combustion chamber. I decided to research why this issue occurred only a few weeks after buying the vehicle. I discovered that the 2015 Ford Fusion's engine, the 1. 5 liter ecoboost engine, has an issue where the cylinder walls are too thin. This leads to a crack in the wall, which causes coolant loss and possible overheating. So, with that in mind, I was cautious with driving it long distances in fear of overheating. However, on Friday, November 1st, because of the coolant intrusion, the car overheated and now cannot be driven and needs to be repaired by replacing the engine.

Check engine light, code p0303. #3 cylinder misfire. Coolant leaking into cylinders 2 & 3 due to faulty casting of the short block. This was a known defect of 2015 Ford Fusion 1. 5 liter ecoboost engine by Ford motor CO. No recall was issued. I was not notified of this defect until it happened. Ford covered repairs for some vehicles but not mine stating I was not within the required timeframe. I had to pay $7200. 00 to repair this problem. I only had 80,000 miles on the car. I feel a recall should have been issued on all these cars since Ford knew about the defect. Please look into this and require Ford to issue a recall. Thank you.

Prior to leaving for a weekend trip, we filled our 2015 Ford Fusion with engine coolant, as it was low. After returning from the trip, we started the care and noticed some white smoke coming from the tail pipe. While traveling around 20mph, the check engine light on the dash began to flash, and the car began to shake violently. We pulled over, and identified that the engine coolant was empty. We stopped at a gas station to fill it up. Upon returning home, we scheduled an appointment with our independent mechanic, to check for a coolant leak. He was able to recreate the white smoke, after noticing that the engine coolant was empty again. He filled it back up, and 24 hours later, the coolant was empty, despite the car not being driven. He advised that there is a possible leak, and he would pressure test it. After testing it, he confirmed that there is no leak in the coolant lines, however, there is a suspected leak within the engine.
