2018 Ford Fusion

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

The engine is losing coolant on a daily basis; I keep gallons of it my car to keep it from running out. The safety risk is the vehicle hoses burst while driving in rush hour traffic and causing a worse delay and maybe injury to myself and passengers. I had the vehicle checked by an independent service station and they recommend a head gasket replacement or engine replacement, and the dealer just brushed me off with the head gasket may need replacing but it is not a recall item. It has not been inspected by any other agency. The check engine light is an on and off again problem -- and that's when the coolant is low the light comes on and when I refill it, it goes off. The vehicle coolant system is losing coolant every two days -- as of this date 4/28/2025, smoke comes from the oil filler cap area but none from the tailpipe. This is a frustrating situation and lawsuit waiting to happen situation that could easily be avoided -- They know it's a problem and want the consumer to reveal this frustrating and potential mega colossal problem to grow out of control.

The contact owns a 2018 Ford Fusion. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. The check coolant and engine warning lights were illuminated. The vehicle was inspected by a local independent mechanic who diagnosed a misfire coming from the engine. The vehicle was not repaired. The vehicle was later towed to a local dealer, where it was diagnosed with a coolant intrusion in cylinders #1 and #2. The vehicle was not repaired. Upon further investigation, the contact related the failure to Customer Satisfaction Program: 21N12, 22-2134, and 19b37; however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 98,207.

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.

We have a 2018 Ford Fusion EcoBoost. The engine started to run hot, we made an appointment to bring to dealer. Morning of the appointment car would not start. We had it towed to dealer. After several hours at the dealership they called to tell us the engine needed to be replaced, quote was $14,000. The issue they explained was coolant in the engine that corroded the engine and all parts. Not salveable, needed to be replaced. We have excellent service records on our car, always keep up with routine maintenance and have owned at least 10 Fords various makes and models. Never had an issue.

My car had a bad shifting linkage which I paid for out of pocket. My 2.0 Ecoboost engine is leaking coolant into my oil and makes a very loud concerning ticking noise, along with reduced engine power and sporadic/random loss of brakes. There has been recalls for these issues on most other Ford Fusion models and this one NEEDS TO BE RECALLED. My engine is going to blow any day now and I will be stuck paying for the rest of my car loan for a vehicle I cannot drive. All of the Ecoboost engines should be recalled for poor design.

Was driving and car started overheating. Looking at coolant levels, they were low. Refilled coolant and car started fine. Next day driving the vehicle, the engine shut down completely. Took the vehicle to Parks Ford dealership in Hendersonville NC to find the problem. I received a call from a service representative and he said there is a coolant intrusion into the cylinder or cylinders and the engine needs to be replaced. I asked to check for recalls and he stated none were found. I did my own research and found many vehicles with the 1.5 liter Ecoboost engine have had this issue and have had a recall in the past. I. Short, Ford has said they will not have my vehicle fixed due to the fact the 3 year warranty has expired and or 85,000 miles have been passed. I have financed this vehicle starting [XXX]. As of now my vehicle has almost 110,000 miles. Doing more research into this Ford has offered a fix for this. A new midi small block replacement and head gasket replacement. Doing more research into this, I have found the vehicle engine could possibly catch on fire if the coolant intrusion is not corrected. The Ford dealership quoted me $9,000 without tax to replace the engine. This just isn't doable. How can this not be a safety issue if the vehicle can and will shut off while driving and potentially catch on fire? Ford should replace the flawed engine design that they have been very well aware of. I am still making payments on this vehicle to own and I cannot risk driving it because it is used to transport my children and my wife, not with the safety factors involved. Help to have the manufacturer flawed design fixed to the updated design, that has no issues of the same, would help blue collard individuals a tremendous amount.
