2018 Ford Fusion Powertrain & Transmission Problems

Coolant Intrusion after the 19B37 customer service program has been completed back in July 23rd 2020 call Ford Motor Company and told them that this service was completed to prevent the coolant intrusion and now it's intruding my car is completely disabled I can't work I bought it with all the money that I had and they said they couldn't do nothing for me they said it's past the 7 years 84,000 miles I tried indicating to them that when disrepair is update was done to the PCM it was supposed to not cause the coolant intrusion but now 6 years later it is causing it so I feel like there should cover it and they basically told me no they don't and have a good day I cannot afford to fix it it's a $6,000 job I do not have that kind of money

CVT transmission completely failed at 150k miles and is not covered by Ford

Shift actuator wouldn’t go into gear I was stranded a few times had to be towed twice. I’ve found a plastic bushing that showed a $4.00 part could be responsible. Deadly for us disabled Vietnam veterans . I can’t walk. Maine has 200 vehicles with the same issues nationwide who knows supposedly the actuator will not be made by ford motors until February 2026. I’m 76 years old this is a hazard I can’t afford to buy another car. Please help us. Or get stranded in the middle of nowhere freezing cold Thank you

Coolant intrusive. New motor needed

Shifter cable bushing degraded and fell off. Causing a condition where the car could not be shifted into or out of gear, and car applied park brake as a safety precaution and could not be disabled until the shifter was manually put back into park by mechanic. This bushing has been under recall for other year fusions but has not been extended to this one. Research on forums shows this is a very common problem. Could be a real safety issue if car cannot be shifted and it needs to be driven away in an emergency. This part should not fail in this short of time, it is made of inferior materials and does not last. No warnings given prior, part fails catastrophically.

The car issued no warning, lights or messages prior to the damage. My [XXX] son was driving and the car started shaking which really scared him as he’s a new driver. I would say the safety of him and other drivers on the road were definitely put in danger. The vehicle has been inspected by a Ford dealership. They stated it had a broken flex plate and short block. Broken Flexplate; Diagnostic $210.00 Parts $1,345.86 (Flexplate, transmission fluid pump, filter, one time use parts) Labor $2,600.00 ($200.00 x 13.0hrs) Sales Tax $125.84 Total $4,281.70 Short Block replacement; Diagnostic $145.00 Parts $2,193.64 (Short block engine/kit, spark plugs, one time use parts) Labor $4,480.00 ($200.00 x 22.4hrs) Alignment $159.95 Sales Tax $205.11 Total $7,183.70 Tow Bill $140.00 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At approximately 67,180 miles, a Ford dealership performed a multi-point inspection on my 2018 Ford Fusion SE with the 1.5L EcoBoost engine due to a check engine light on. The Ford dealership diagnosed the vehicle with a coolant intrusion into cylinder 2. The Ford dealership recommended the replacement of the short block and gasket kit, with an estimated repair cost of $7,465. This type of issue diagnosed for my vehicle is a known failure issue for 1.5L Ford EcoBoost engines documented in Customer Satisfaction Program 21N12, which covers coolant intrusion and engine damage in this engine type. Despite the Ford dealership diagnosis of my vehicle matching what is described in Customer Satisfaction Program 21N12, I was informed that my vehicle is not eligible. The Coolant intrusion into cylinder 2 is an issue that poses a safety risk due to engine misfires, stalling, overheating, and possible sudden loss of engine power while driving. In my case, my vehicle has become unreliable and unsafe for regular driving. A Ford dealership inspected the vehicle, confirmed and documented the issue, and the repair quote, diagnostic report and diagnostic payment receipt are available upon request. Ford has declined assistance despite the vehicle’s low mileage and clear alignment with known engine defects. I mailed a formal appeal letter to Ford Motor Company and I am filing a complaint with my state attorney general. This widespread issue affects customer safety, and vehicle safety standards and deserves further investigation, as many other Ford owners of vehicles with 1.5L EcoBoost engines have reported similar failures.

The contact owns a 2018 Ford Fusion. The contact stated while driving 30 MPH and depressing the accelerator pedal, the vehicle hesitated and stalled. There was no warning light illuminated. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and transferred the contact to the NHTSA Hotline to report the failure. The approximate failure mileage was 72,000.

Car started running rough then white smoke was coming out the exhaust. Took it in to have it checked out by Ford and they said it was coolant intrusion into the cylinders. Now they want $9,000 to replace an engine that has less than 60,000 miles. I see online that this is not new and definitely a design flaw with this engine and many others.

While maneuvering in parking lot car would not shift from Reverse to Drive after backing out of parking place, error on dash stated shift module failure. Tow truck driver manually engaged shifter to drive, too car to Freeman Ford. Upon inspection shifter grommet at transmission had worn not allowing car to change gears, $4 in parts, $300 in labor to fix. Fortunately the car was just blocking a post office parking lot, if this had been a maneuver in an intersection it could have caused an accident. There was no indication this failure was going to occur.

The contact owns a 2018 Ford Fusion. The contact stated that after his girlfriend was occupied and parked in the residence, while attempting to reverse the vehicle the gear shifted independently into park. The contact mention he lifted the front end of the vehicle, and he noticed the shifter cable detached from the transmission shifting arm. The contact was able to attach the shifter cable on the transmission shifting arm but also noticed the shifter cable bushing has detached from the transmission as well. The vehicle was not taken to be diagnosed. The vehicle was not repaired however the contact mention the vehicle will be getting repaired on March 29th. The contact related the failure to the NHTSA Campaign Number: 22V413000(POWER TRAIN). The insurance company had not been contacted yet. The manufacturer was made aware of the failure they informed the contact that NHTSA calls the manufacture to have recalls on their VIN. The contact was referred to NHTSA to file a complaint on the failure. The failure mileage was 102.000.

The check engine light came on and something about the cooling system. I can’t totally remember. The Service desk confirmed the eco boost engine has known issues of the cooling system which may cause the engine to go bad. Reported I needed a new engine and transmission. Then after they had started that job and after I put $1,500 down they called me back and said the radiator has issues from it all and needed changed as well. I asked him if all fords only lasted approximately a 100,000 miles or just this one and he responded that it is a known issue by ford and happens with this engine. It cost me approximately $15,000 out of pocket to get the car fixed. Within a week there were more “issues” with the engine and I am now being charged over $300.00 to fix this part that they didn’t change even though they put in a new engine.

Sensor that believe the car to be overheating shut the car down while driving in on the highway.. turning the car off completely or powering it down 99%.

At 135,815 miles, my 2018 Ford Fusion SE experienced a sudden transmission failure while driving, with no prior warning signs. The vehicle was towed to Certified Transmission, where technicians confirmed: Transmission fluid level was correct but black/degraded. Multiple failure codes were present. Transmission pump whined and stopped functioning. Diagnosis: Internal transmission failure (6/17/2024). The shop stated this issue is common in these transmissions. The entire transmission had to be replaced. At 141,164 miles, just 5,349 miles later, the engine shut off on the highway while driving, again with no warning lights. After pulling onto the shoulder, it restarted after 10 minutes but was smoking heavily. Coolant was critically low in the reserve tank. Diagnosis: Cracked cylinder head due to coolant intrusion, a known defect in 1.5L EcoBoost engines. I contacted Ford Customer Care about CSP 21N12, but they refused assistance since my vehicle exceeds 84,000 miles, despite this well-documented defect. Safety Concerns: Unexpected transmission & engine failure while driving creates a serious risk. Engine shutoff on the highway could have led to an accident. Coolant intrusion in 1.5L EcoBoost engines is a known issue, yet Ford has failed to notify all owners. This issue affects many owners and creates major safety risks. I urge the NHTSA to investigate and consider a mandatory recall to prevent further incidents.

Transmission cable shifter bushing was defective and popped off of transmission shifter. This subsequently caused the transmission control module to overwork and fail.

After I bought from personal owner feb. 3rd 2025 I drove 50 miles and overheated before I made it home . The check engine light came on it showed up as a bank 1 bank 3 misfire also camshaft position sensor so I replaced these things and it still was losing coolant oil is just fine. Every time I would drive it it would still overheat I would keep putting more antifreeze in to make it home. It started to misfire very badly still loosing coolant jerking when I would try to give it gas and some times would hardly move . I changed the thermostat still the same . So then I replaced the catalytic converter still nothing changed . Took it to a shop and he looked all over it couldn't find anywhere that the coolant could have been escaping he did find and replace the vvt solenoid. Worked for a very short period. So as the problems progressed and the car wouldn't even go 3 minutes without overheating and jerking losing almost all of its power my brother put a head tester on it and conducted the test to show it has a bad head so its not able to be driven to be checked by any dealership or anything also isn't under recall . Yes it is a safety hazard when I was able to drive it was losing power I couldn't gain speed even with a full pedal so took the risk of being hit from behind if a car had come up behind me .

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine experienced coolant intrusion, which is a known defect in certain Ford EcoBoost engines. My independent mechanic diagnosed the issue after I noticed significant engine performance problems. The affected components, including the engine block and cooling system, are available for inspection upon request. How was your safety or the safety of others put at risk? Coolant intrusion can lead to engine overheating, misfires, and in severe cases, engine fires. This significantly increased the risk to my safety and that of others on the road. Had I not addressed the issue promptly, a fire could have occurred while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem was confirmed by an independent, certified mechanic—not by a Ford dealership. The dealer failed to properly diagnose or even acknowledge the problem, which appears to be common based on other consumer complaints. Ford did not identify what was truly going on with the vehicle, despite clear symptoms. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Ford has not inspected the vehicle. The manufacturer was notified, but they declined to take responsibility or offer a solution. There was no inspection by police or insurance representatives, as the issue was caught before a fire or accident occurred. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The engine began running rough and hesitating under acceleration. I also noticed excessive white smoke from the exhaust, and the check engine light came on intermittently. These symptoms began appearing several weeks before the full diagnosis, and Ford service failed to address them accurately during prior visits
