2015 Ford Fusion Engine

Was driving g on the freeway and car began shaking about 1mile later rhe car would not go past 10 miles an hr without making a loud noise everything was upkept with my car ontop of all recalls and now I have a car that I had to finish paying off without being able to drive it for almost 2 years and can't seem to fund a solution on either the dealer fixing the power train or giving me a refund

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.

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.

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.

The contact owns a 2015 Ford Fusion. The contact stated that coolant would evaporate from the engine without warning. The contact stated that no warning lights or visible signs of a leak were present. The vehicle was taken to an independent mechanic and the mechanic was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was provided a case number. The contact was then referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 90,000.

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.

I got an engine temperature warning, then I noticed the coolant reservoir was empty. I filled it back up and everything went back to normal. I was driving down the interstate when the check engine light came on. I had a few misfires and was able to make it back to a dealership, who then diagnosed the vehicle and said it coolant intrusion due to an engine block leak. Charging over $9000 in repairs

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

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 driving at various speeds, the engine overheating warning light illuminated. The contact stopped the vehicle, and the vehicle was towed to an independent mechanic. The vehicle was diagnosed, and it was determined that an engine sensor had failed and needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that the failure reoccurred 2 more times. The contact stated that during recent failure, there was a misfire coming from the engine and the engine was idling rough. The vehicle was driven to the same mechanic, who diagnosed the vehicle and determined that there was coolant intrusion into the engine block, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 175,000.

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.

The contact owns a 2015 Ford Fusion. The contact stated while driving approximately 40 MPH, the message that the engine was overheating was displayed. The contact stated that the temperature gauge indicated that the engine was hot(H). The contact drove the vehicle to an independent mechanic who diagnosed the vehicle and determined that there was coolant into the cylinder. The contact was advised that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the Hotline to report the failure. The failure mileage was approximately 113,000.

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.

The contact owns a 2015 Ford Fusion. The contact stated that while her husband was driving approximately 30 MPH, the vehicle was emitting white smoke from the exhaust pipe. The contact stated that her husband had not observed any warning lights being illuminated. The contact stated that the vehicle stalled, and her husband had the vehicle towed to the residence. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact researched online and related the failure to Customer Satisfaction Program: 21N12 - Coolant intrusion into the short block (Engine and Engine Cooling). The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 128,000.

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.

Coolant Intrusion in Cylinder 2 and 3.

The contact owns a 2015 Ford Fusion. The contact stated while driving at an undisclosed speed, the engine overheated. There were no warning lights illuminated. The contact pulled over to the side of the road and noticed there was white smoke coming from under the hood. The vehicle was towed to the residence and then was towed to an independent mechanic to be diagnosed. The contact was informed that coolant intrusion into the engine had damaged the engine and that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was informed of the failure and confirmed that the VIN was not under recall for the failure. The contact was advised to contact the NHTSA Hotline to report the failure. The vehicle was towed to the residence and had not been driven since. The failure mileage was approximately 70,000.

Unknown. La palanca de cambios no funciona. No se pone en parking y cuando el carro se apaga no quiere prender.

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!!!!

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.

The contact owns a 2015 Ford F-150. The contact stated that the engine was louder than usual, and the vehicle was running rough while driving at various speeds and idle. There were no warning lights illuminated. The vehicle was taken to the dealer and was diagnosed with low compression in cylinders #2 and #3 with a PSI of 801 in cylinders 1 and 4 with a PSI of 100. The dealer informed the contact that the deal PSI level was 145. The failure related to Technical Service Bulletin: 19/2375 - NHTSA ID Number: 10169884 (Engine and Engine Cooling) then referred the contact to the manufacturer to confirm inclusion. The dealer stated that the engine needed to be replaced. The vehicle had not been repaired. The manufacturer was informed of the failure and confirmed that the VIN was not included. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 130,000.

My 2015 Ford Fusion 1.5L Ecoboost has exhibited behaviors that are reflected in TSB 22-2229 or the most updated version of this TSB. Ever since I purchased the vehicle in January 2023, I have had to refill the coolant reservoir more than 5 times, and have had blueish-white smoke billow from the exhaust. Just today, February 12, 2024, when leaving my house, upon acceleration, the same tinted smoke was expelled from my exhaust, leaving a cloud in two different spots in my neighborhood. And when I left work later this evening, I had to refill my coolant AGAIN because the reservoir was empty! If Ford knows this is an issue, why has no recall happened?

Coolant is leaking into cylinder 3 of the engine causing a misfiring and code P0303 to present itself. White exhaust is seen when the vehicle is turned on. Lots of vibrations present and the check engine light stays on. My mechanic provided me with the documentation of what he found and said it would cost 14 thousand dollars to replace. Mechanic said to bring it to a ford dealership to confirm their findings. I went to a ford dealership and explained to them what was found by my mechanic and told them to do a diagnostic on their end. The dealership confirmed the findings and sent all documentation to ford corporate headquarters with price quotes and everything so that they can repair the issue since this problem is seen on all ecoboost engines in all ford models. Ford corporate denied everything and said that my vehicle was too old and that this is not a known "issue" with their vehicles. I searched online and found multiple people having several issues with ford fusions that have the ecoboost engine problems. Ford is denying everything and they know this has been an on going issue for a long time. The first time this issue appeared for me was on May of 2024.
