The contact owns a 2019 Ford Fusion. The contact stated that while driving approximately 30 MPH, the check engine warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with a leaking the head gasket, which allowed coolant into the cylinders. Additionally, the message "Coolant Low - Overheating Soon" was displayed, and there was black smoke coming from the tailpipe during startup. The contact stated that the vehicle was undrivable and associated the failure with a class-action lawsuit. The dealer was notified of the failure by phone and informed the contact that there was a fee for the diagnostic test. The contact declined. The manufacturer was notified of the failure by phone and filed a report. The contact was awaiting a call back from the manufacturer. The failure mileage was approximately 57,000.

My 2018 Ford Fusion suffered a sudden and complete engine failure caused by internal coolant intrusion — coolant leaking into the cylinders and destroying the engine. Pep Boys diagnosed that the failure developed internally over time and could not have been avoided by the owner. This is a known Ford factory defect in the 2.0L EcoBoost engine, documented in Ford's own publications (SSM 47204, SSM 47462, TSB 19-2346, TSB 22-2229), all of which cover the 2018 Fusion. The root cause is Ford's open-deck engine-block design, which allows coolant intrusion and cracking between cylinders. Ford corrected the design in 2019 production. A federal class action (Nelson et al. v. Ford, E.D. California) and the federal safety agency defect petition DP26008 concern this same defect. The sudden loss of engine power created an unsafe driving condition. My warranty claim was denied based on a 'blown head gasket' finding, which is the symptom of the factory defect, not the cause.

We purchased this 2017 Ford Fusion 1.5L EcoBoost in August 2022 at 48,968 miles. At 55,940 miles, the vehicle developed a documented coolant leak requiring water-pump replacement. At approximately 75,520 miles, the coolant level was again documented as requiring attention. At approximately 84,189 miles, the vehicle experienced low coolant, low oil, white/gray smoke and rough running. Manteca Ford identified Ford TSB 22-2322 and ultimately performed a major short-block replacement. Despite this major engine repair, mechanical and drivability problems continued. At approximately 101,375 miles, we returned the vehicle to Manteca Ford specifically for loss of power and hesitation. The Ford technician verified a “noticeable loss of power” and lack of full boost. Manteca Ford diagnosed and replaced the turbocharger. The problem was not resolved. Only approximately 205 miles later, at 101,580 miles, the vehicle returned to Manteca Ford because it was still hesitating during acceleration. Manteca Ford then identified DTCs P0729, P07AA, P2703 and P2704 and documented “TRANSMISSION INTERNAL MECHANICAL FAULTS,” including an incorrect sixth-gear ratio and friction-element faults. The dealer recommended replacement or teardown of the transmission. We are extremely concerned about the safety implications of this history. Loss of power and hesitation during acceleration can create a serious hazard when merging onto a highway, entering or crossing traffic, or attempting to accelerate to avoid a collision. This vehicle has experienced repeated engine/powertrain problems despite major repairs, and we are concerned the transmission condition may have been developing during the earlier loss-of-power/hesitation complaints. We request that the federal safety agency evaluate this history for a potential safety-related defect or broader pattern.

The contact's brother owns a 2020 Ford Fusion. The contact stated that while the owner was driving 35 MPH, the engine overheated and there was misfire coming from the engine. The check engine warning light illuminated, and there was fluid leaking into the engine. An independent mechanic was contacted by phone. The vehicle was taken to the independent mechanic and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The contact was informed that the failure was a known failure with the vehicle. In addition, the contact was informed that the failure was due to the manufacturing design of the engine. The manufacturer was contacted by phone and a case was filed. The failure mileage was approximately 72,000.

My 2018 Ford Fusion Titanium FWD (VIN: [XXX]) suffered a catastrophic engine failure while driving, causing sudden vehicle overheating, severe engine misfires, and a dangerous loss of power on the roadway.A certified Ford dealership inspection (Invoice #XXX) confirmed that the vehicle has a textbook manufacturing flaw known as EcoBoost coolant intrusion. A pressure test showed an immediate 5 PSI drop within 10 minutes, and a borescope confirmed that engine coolant is actively leaking across the block interface and pooling directly inside the engine cylinders (cylinders 2 and 3).This is a known, widespread structural engineering defect in Ford's block casting that creates a severe, sudden safety hazard by causing vehicle stalling and clouding exhaust smoke while operating at highway speeds. The vehicle is now entirely unsafe to drive and requires a full engine block replacement. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On October 16, 2017, we were driving this vehicle on the interstate when we noticed smoke in the rearview mirror. We pulled over right away, and within seconds of getting out, the car was engulfed in flames. It burned so fast that by the time firefighters arrived, about seven minutes later, there was nothing left of it. Neither of us was physically injured, but we got out with almost no time to spare. The fire department responded and a report was filed. The car was equipped with the 1.6L GTDI EcoBoost engine and falls within the population of Safety Recall 17S09 / the federal safety agency 17V‑209, which covers localized cylinder head overheating and cracking that can cause a pressurized oil leak and an engine compartment fire. At the time our car burned, the interim recall notice had gone out but no remedy parts were available; the actual recall repair did not begin until January 5, 2018. Ford later contacted us and offered a small settlement, conditioned on signing away any right to bring future claims. We declined.

My engine coolant keeps on overheating, I’ve tried changing the antifreeze tank out for a brand new one and it helped the issue for a while but I have to relieve the pressure myself which is a hazard. I’ve had to change the coolant in the tank more than 5 times and it just seems like it’s leaking somewhere other than going into the engine to cool it. When I go out roundabouts off a highway the engine overheats and makes the car go into a safe mode where it won’t go and I have to stop on the side of the road. When I’m driving with my heat on the heat will go cold when I slow down. If I’m not going over 3x1,000 RPMs it will go cold and fluctuate. This has been going on for months now.

Exhibited signs of a coolant leak followed by throwing a code about cylinder 4 misfiring. Took my car to the dealer who confirmed that there is coolant leaking into cylinder 4, and it is similar to other defects found in many 1.5 liter ecoboost engines from this model line. Was told that my VIN did not qualify for the recall that is only for the ecoboost 2.0 liter engines even though they have the same defect.
