2019 Ford Fusion

My 2019 Ford Fusion 2.0L EcoBoost (89,000 miles) experienced a sudden, severe engine malfunction due to a known manufacturing defect. The vehicle exhibited severe engine shuddering and a harsh cold-start misfire upon ignition. A diagnostic scan revealed trouble codes P0316 (Misfire on Startup), P0302 (Cylinder 2 Misfire), and P0304 (Cylinder 4 Misfire). A mechanic verified that these codes are the result of internal coolant intrusion into the engine cylinders, exactly as documented in Ford Technical Service Bulletin TSB 19-2346. The structural design flaw in the engine block allows engine coolant to breach the cylinder head gasket area and pool inside the combustion chambers. This presents a critical safety hazard: the vehicle is at risk of sudden engine stalling while driving on public roads, a complete loss of motive power in traffic, and potential engine hydro-lock, which can cause catastrophic mechanical failure or an engine compartment fire. Ford is refusing to address this safety defect outside of warranty, leaving a hazardous vehicle on the road.

The contact owns a 2019 Ford Fusion. The contact stated that after receiving notification of NHTSA Campaign Number: 23V440000 (ELECTRICAL SYSTEM); that the parts were available, the local dealer was contacted, and the contact was informed that parts were still not available and were on back order. The manufacturer was notified of the issue and confirmed that parts were still on back order. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.

My 2019 Ford Fusion has been diagnosed with the prominent EcoBoost Coolant Intrusion defect requiring a newer 2020+ redesigned engine replacement. Ford is refusing to replace it or provide any discounts even though it's clearly a engineering defect. The vehicle has just 38,500 miles in 7 years of ownership. It has been regularly well maintained & not driven hard. This is inexcusable that Ford is not standing behind their product that has a plethora of well documented failures on these particular flawed design engines, namely the 2.0L EcoBoost that came in this vehicle.

When driving all of a sudden I feel the car loose power as I accelerated the car just reeved up and slowed down to a full stop. I put it in park turned it off sat for a few minutes. Restarted the car and put it in drive the engine RPM made a reving sounds but did not engage. I had to wait for a tow truck. When the tow truck arrived he started the car and drove it on the ram and locked it in and drove the car to my home. Tow truck driver unlocked my car and drove it off the bed of his truck. The car starts and that is it. It will dive a few feet then disengage.

All four tires separated at the bead, catastrophic tire failure. Thank goodness they went flat in the driveway and not traveling at 65 mph on the interstate. 235/50R/17. These are 80,000 mile tires and this occurred at 35,500 miles. Purchase from Costco and when we went back they basically told us they would only warranty 20% of tire even though the warranty should have been 50%.

The vehicle experienced engine failure due to coolant intrusion into the cylinders on a 1.5L EcoBoost engine. Symptoms included coolant loss, engine misfires, rough running, check engine light, and eventual engine failure requiring engine replacement. The problem has been confirmed by Ford and is consistent with the known coolant intrusion defect affecting many Ford 1.5L EcoBoost engines. Ford issued Customer Satisfaction Program 21N12 for certain affected vehicles due to this exact issue. The vehicle has approximately 76,000 miles and is under the mileage limit referenced in Ford’s program, but Ford denied full coverage and only offered partial financial assistance toward the repair. This issue creates a serious safety concern because the engine can lose power, misfire, overheat, or fail unexpectedly while driving. The failure appears to be caused by a defect in the engine design allowing coolant to enter the combustion chamber. I believe this is a widespread defect and should be covered for all affected vehicles experiencing coolant intrusion and engine failure.
