2015 FORD FUSION Engine Problems

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

On 2/4/26, I experienced a slight skip while driving, But did not continue. The very next morning while in reverse, A winding sound started. Put car in drive pulled out onto main road, drove fine, not even half a mile. Stopped at sign, pulled out onto main road a main road, and car would not go, would not go in gear at all. No one was hurt, but received a few horn honks. Made it to side of road, put the car in sport/manual mode, did not help. Manage to make it about a mile up the road where I was able to safely park it in a parking lot. The check engine symbol came on a couple of weeks prior, but went away after a day. Did not come back on until this particular day 2/5/26. Nothing, no problems leading up to this. Conveniently the extended warranty went out...

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.

I have been having issues with the vehicle where it will stall. This even happened when I was driving on the NJ turnpike, it stalled while driving and I had to pull over (thankfully I could) to restart the vehicle. It took the dealer 3 weeks to finally figure out the issue and tracked it down to a bad BCM (Body Control Module). I researched this further and found some interesting information. A significant number of 2015 Fusion owners report similar electrical glitches, with some experiencing a complete loss of power to multiple systems, including the center console, AC, and power windows. Diagnostics have identified water intrusion and corrosion in specific connectors, such as C134 near the front bumper, as a root cause, which can be resolved by cleaning and applying electric grease. However, a failing BCM itself is a common diagnosis, especially when multiple systems fail simultaneously and no...

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

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 70-75 MPH on the interstate, the vehicle stalled. There was no warning light illuminated. The contact was able to pull over and restarted the vehicle. The message "Transmission Not in Park" was displayed. The contact stated that while veering to the left lane, the vehicle started to shudder. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacture was not made aware of the failure. The failure mileage was approximately 216,700.

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 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...

I was driving on the highway in my car stop going then it start rolling backwards a little then i hit the breaks then put in park in put it back in drive then it started driving again then my brake lights came on and didn’t go off for about a week I have to unhook the battery I have a 8 year old son I was on the way to the hospital because my grand father was on life support when all this took place there was trucks going around us we almost got hit my three car thank god I made it home safe then I got. Home in my car just keep getting load as if I’m hitting the car there’s a load sound it makes when I start it up in i dont feel safe driving it … when out it being check out i really...

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.

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.

Coolant Intrusion in Cylinder 2 and 3.

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.

The contact owns a 2015 Ford Fusion. The contact stated while driving at an undisclosed speed, there was heavy white smoke coming from the exhaust pipes before the vehicle shut off unintendedly. The contact stated that there was a leak coming from the catalytic converter and the check engine warning light was illuminated. The vehicle was taken to an independent mechanic who discovered a blown head gasket due to coolant intrusion into the cylinders. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that there were no recalls on the vehicle. The contact was provided a case number and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 134,000.

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...

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...

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.

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...

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.

The contact owns a 2015 Ford Fusion. The contact stated while driving at an undisclosed speed, the engine over heated with the engine temperature warning light illuminated. The vehicle was driven to the shoulder of the roadway. The contact stated that the vehicle lost motive power with the engine overheating warning light illuminated. The contact stated that the vehicle shut off and failed to restart. 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 the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 180,000.

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.

My vehicle will not turn on after refueling, but there are no signs of visible damage. The check engine light remains illuminated, and the code read for the O2 sensors. The RPM jump up and down at the slightest push of the accelerator, and occasionally the engine will shut off when RPM drops to idle speed.

NO WARNING LIGHTS PRIOR TO THE PROBLEM. THE CAR WAS DIAGNOSED BY A FORD DEALERSHIP. THE ENGINE NEEDS TO BE REPLACED DUE TO COOLANT GETTING IN THE CYLINDER. THERE IS A TSB ABOUT THIS ISSUE. IT IS A KNOWN PROBLEM FOR THIS CAR. NOW FORD IS OFFERING NO ASSISTANCE IN FIXING THE PROBLEM.

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...

I noticed the coolant level keeps getting low. There was a large amount of white smoke coming from the exhaust. It sounds like water in the dash. Now the car is barely drivable. No warning lights have come on.

Spent savings on my kid’s car. Now Needs New Engine I bought my kid a 2015 For Fusion from my best friend. It was under 100k miles. I purchased it in December. She had checked out, regular oil changes. She never had issues aside from the brake light. I paid $8000. With tax, tag, title and insurance start, it was over $9000 We take it in January took to my mechanic whom I have been using almost 20 years, very reliable and honest, for oil change and to fix the wiring of the brake light. That cost a few hundred. March the AC went out. That was about $1400. Then took in for next oil change and had to get rear brakes done, which was prepared for that one, it was time. That was a few hundred. Then the car starts shaking, take it back, they replace a coil pk...

1. The Ford dealership in Glendale, CA refused to do the brake pedal recall, but it shows as complete. The car was bought at this dealership and never had work done to the brake pedal. (NHTSA CAMPAIGN ID: 23V162000). 2. The car burns oil way quicker than it indicates. This has happened twice to me now where I had to replace the entire engine because I completely ran out of oil before I was due for a change. I check my oil religiously after that because there are no signs of leakage. I checked my oil [XXX] after having my oil changed on [XXX] and its bone dry I have only driven under 3000 miles. I still have over 2000 miles until im suppose to change my oil and its only been 2 months. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle began having low coolant, smoking from tail pipe, running erratically, and numerous codes including ( P-300 codes). My only transportation and before I made it home the engine turned off completely and did not crank or turn over at all.. I felt the engine was about to catch on fire and so I got out and called family member for a tow and ride home. My car has been sitting in the driveway for at least 2 months. Im a veteran, and making it to doctors appointments is a big issue.

This car has cut off (lose power)twice while driving. Crank back up fine . It’s definitely a hazard if your on the interstate.

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?

We notice antifreeze was disappearing at a very fast rate without a sign of a leak found out it was leaking in the engine

Coolant intrusion into cylinders of engine. Coolant leak into the cylinders can lead to corrosion, misfires, engine failure, and even potential car fires. Local ford mechanic confirmed thus was the issue and that he's personally seen SEVERAL others. No warning lights

The contact owns a 2015 Ford Fusion. The contact stated that while driving on a highway at unknown speeds, the vehicle lost motive power and stalled. The contact activated the hazard lights and veered to the side of the road. While the contact’s wife was reversing, the vehicle began to drive roughly and stalled. Upon accelerating from a stop light, the vehicle stalled. The check engine warning light was illuminated. The contact's son inspected the vehicle and received codes for low fuel pressure. The vehicle was taken to an independent mechanic, who informed him that there was low fuel pressure and that the fuel pump and fuel sensor needed to be replaced. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was not repaired. The manufacturer was contacted and opened a case and referred the contact to the NHTSA Hotline. The failure mileage was...

The contact owns a 2015 Ford Fusion. The contact stated while driving 60 MPH, the vehicle decelerated independently and started jerking. The contact stated that the vehicle failed to exceed 30 MPH while depressing the accelerator pedal. The check engine warning light was illuminated. The contact stated that several unknown repairs were performed on the vehicle regarding the failure; however, the failure persisted. The vehicle was towed to an independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.

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.

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.
