2019 Ford Fusion: sudden loss of power

Filed Sep 21, 2026 · Electrical, Fuel system · LA

I am the original single owner of a 2019, paid-off, gas Fusion with less than 54,000 miles, a spotless maintenance record, and no accident history. The vehicle suffered a sudden, instantaneous total loss of motive power. The loss of electric power steering assist and loss of power brake assist while driving through a live intersection with no warning lights or prior engine shuddering nearly caused a severe, life-threatening, or even fatal collision. The vehicle was removed from the intersection by physically pushing it with the assistance of other passing motorists and local police. I immediately called and requested towing services through the manufacturer. Services arrived 2 hours later. They started the car with no issue and drove it onto the tow truck. No engine lights or warning lights were present; the vehicle did not stutter or shake, and the vehicle had a 1/4 tank of gasoline. The vehicle was delivered directly to the Dealership. After it stalled and once it was removed from the intersection, no attempt was made to restart the vehicle until the towing service arrived. The dealership has had the vehicle for 2 weeks and claims they cannot diagnose the cause; there are no active diagnostic codes, and they have not been able to replicate the failure regarding this potentially fatal electrical shutdown. It is completely unacceptable and dangerously irresponsible for a dealership to hold a vehicle for 2 weeks, then suggest "picking it up, add some gas" simply because they haven't found any issues and "it should be fine." I cannot, in good conscience and out of protection of myself, my family, and other motorists, continue operating a vehicle that exhibits life-threatening intermittent failures.

The vehicle experienced engine failure due to coolant intrusion into the cylinders on the engine. I've experienced engine misfires, rough running, check engine light, and I'm worried I'm going to see an eventual engine failure requiring engine replacement. The BIGGEST issue is I've had total loss of power in my engine while on a public road more than once, before the check engine light ever came on. Its terrifying. It is dangerous. And Ford is aware it is dangerous. Ford issued Customer Satisfaction Program 21N12 for certain affected vehicles due to this exact issue, but my vehicle is past the warranty so it's SOL. The failure appears to be caused by a defect in the engine design allowing coolant to enter the combustion chamber. This is clearly a widespread defect as Ford had to create their limited warranty for it. This is something that needs to be recalled for all affected vehicles experiencing coolant intrusion and engine failure because it is not safe to be on the road.

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.

This 2019 Ford Fusion (2.0L EcoBoost, 6F35 transmission) has had THREE identical flexplate/flywheel failures (GSAR code 6375), each diagnosed by a different Ford-authorized dealer. FAILURE 1 (Nov 2021, 51k mi): Lost power at highway speed on interstate. Coasted to stop, would not restart. Broken flexplate. Ford repaired under warranty, reimbursed all expenses. FAILURE 2 (May 2022, 59k mi): Would not start, starter whined. Same diagnosis - broken flexplate. Ford repaired under warranty, reimbursed all expenses. FAILURE 3 (Feb 2026, 133k mi): Broke down on busy road. Police responded with emergency lights until tow arrived. Same diagnosis - broken flexplate, free spinning. Ford REFUSES repair despite confirming Customer Satisfaction Program 22N12 applies to this vehicle. SAFETY: Each failure causes sudden complete loss of drivetrain function with no warning. Failure 1 was at highway speed. Failure 3 required police response on a busy thoroughfare. The manufacturer issued CSP 22N12 acknowledging this defect. A manufacturer rep confirmed on 3/20/2026 that the program applies to this vehicle, then refused coverage citing mileage. The flexplate part was revised (suffix D to E) between failures, indicating the manufacturer knew the original design was defective. Three dealers, three techs, identical diagnosis each time. Vehicle is at dealer, available for inspection.

Vehicle has a known Ford 2.0L EcoBoost coolant intrusion / head gasket defect per multiple complaints on different forums on recently googled searches. At approximately 126,000 miles, vehicle began losing coolant with no visible external leaks, producing white smoke on startup, rough idle/misfires, and check engine light. Vehicle also began overheating intermittently. Heating system stopped working, indicating coolant flow failure. Symptoms are consistent with internal coolant intrusion into cylinders due to head gasket failure, a widely reported defect in Ford EcoBoost engines. Issue presents a safety risk due to potential engine failure while driving, loss of power, and overheating. Vehicle requires major engine repair or replacement. This failure occurred despite regular maintenance and appears to be a premature engine defect, not wear and tear. I was recently at the dealership on December 8th with no other issues detected after they replaced a part on my car that failed that I had to pay for ( a P175B-00 ). This had nothing to do with what is going on currently, they ran tests at this dealership and did not detect anything as of December 8th. This was at a ford dealership. Tests were ran and inspected by manufacturer. Fast forward to a week ago I started having the above symptoms and this was diagnosed by family-friend auto mechanic. I have had multiple issues with this car. The transmission blew at 50 thousand miles, the sun roof leaked ( the seal for the sunroof was defective) into my prnd control shifter causing thousands of dollars in damage, a P175B-00, causing my car to not be able to park, causing chaos for weeks. I have only owned this car since December 2020. I still owe 7 thousand on this vehicle and I am at a complete loss. I really just want ford to take accountability for this make and model as it never fits the guidelines for recalls on anything. I want justice for myself and others with these multiple issues coming from ford cars.

This vehicle has a known issue by Ford. In Ford TSB 22-2229 it acknowledges "P0300, P0301-P0304,P0316, P0217, P1285 and/or P1299 stored in powertrain control module (PCM). This may be due to coolant intrusion into the cylinder. To correct the condition, follow the Service Procedure to replace the long block engine assembly." When explained, it states that this issue could cause reduced engine power which obviously be a very dangerous situation if the vehicle is traveling at highway/interstate speeds. The replacement of the long block engine assembly is a complete engine replacement that Ford is not assuming responsiblity for either from a safety or cost standpoint. We are regularly receiving these diagnostic codes now and a recent diagnosis from a Ford dealership confirmed the need for a long block engine assembly replacement which is extremely costly and right now is cost prohibitive, especially for a vehicle that is only 5 years old and has less than 100,000 miles on it.

Hello. Recently it was discovered by my mechanic when they were doing an oil change that there was a crack discovered between the engine and transmission. This crack appeared to be a part of the flex plate which has been causing transmission fluid to leak and ultimately losing power in some cases when driving. When doing research, my vehicle did not come up under recall looking everywhere I could with my VIN#. I’m afraid for my safety and the safety of my family. A picture uploaded below will show the crack and some transmission fluid visibly leaking. Please help. My vehicle currently has 55,646 miles.
