The contact owns a 2018 Ford Fusion. The contact stated that there was an abnormal sound coming from the rear of the vehicle. In addition, the engine made a bubbling sound after turning off the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where an engine misfire was diagnosed, and a fuel odor was detected. The mechanic determined that the engine had failed and needed to be replaced. The failure mileage was approximately 138,000.

My 2018 Ford Fusion suffered a sudden and complete engine failure caused by internal coolant intrusion â 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)…

Capital Ford of Wilmington diagnosed my vehicle with coolant intrusion into cylinder 2, accompanied by diagnostic trouble codes P0302 and P0316, after check engine light came on. I have been advised that the vehicle requires a complete engine replacement, with an estimated cost of $13,180.89. The vehicle has experienced sputtering and hesitation, creating concern that it could lose power or stall. These symptoms are concerning. After researching this issue, I have learned that coolant intrusion is a documented problem associated with certain Ford vehicles equipped with the 1.5L EcoBoost engine produced during the 2017â2019 period. Ford has addressed this issue through Technical Service…

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…

My engine coolant keeps on overheating, Iâve 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. Iâve had to change the coolant in the tank more than 5 times and it just seems like itâs 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 wonât go and I have to stop on the side of the road. When Iâm driving with my heat on the heat will go cold when I slow down. If Iâm not going over 3x1,000 RPMs it will go cold and fluctuate. This has been going on for months…

The contact owns a 2018 Ford Fusion. The contact stated that the check engine warning light was illuminated. Additionally, there was white smoke coming from the exhaust pipes. The vehicle was taken to an independent mechanic several times, and the contact was informed that the engine was consuming antifreeze. The ignition coils and spark plugs were replaced; however, the failure persisted. The mechanic associated the failure with the engine. The vehicle was taken to a dealer, where it was diagnosed and determined that the short block was warped and that the engine needed to be replaced. The vehicle was scheduled to be repaired. The contact researched the failure and stated that it was a…
