2022 Ford Bronco: engine failure

Filed Jun 16, 2026 · Engine, Transmission · ID

While operating the vehicle under load, the vehicle suffered a sudden and severe loss of engine performance, followed immediately by loud metallic banging from the engine bay. The vehicle lost all power and was immediately disabled (LIMP MODE), presenting an imminent highway safety hazard.The Physical Damage: Subsequent mechanical teardown revealed deep vertical cylinder wall scoring, heavy raw fuel residue in the engine oil pan, and a blown head gasket. Relationship to Active Safety Defect: This catastrophic block failure perfectly mirrors the progressive failure profile of the federal safety agency Campaign 25V455 / Ford Safety Recall 25S75 (Low-Pressure Fuel Pump Failure). Internal component degradation in the fuel tank delivery module dropped fuel pressure to the engine. Under turbo boost, this starvation induced an extreme, instantaneous lean-out condition. The resulting low-speed pre-ignition (LSPI) exploded and shattered the internal piston rings (the metallic banging), leading to mechanical wall gouging, unburnt fuel wash into the lower crankcase, and a secondary blown head gasket. Request for Action: Ford's current VIN parameters for Recall 25S75 have not yet captured my specific vehicle despite it matching the exact production window, component setup, and catastrophic failure sequence. I am requesting that the federal safety agency log this case as clear evidence of consequential engine destruction originating from the 25V455 pump defect, and evaluate whether Ford's recall scope must be expanded to protect other consumers from highway engine failures.

The Incident: While operating the vehicle under high load, the driver received an explicit "Service Engine Soon" powertrain malfunction alert stating: "The powertrain control module lost communication with the vehicle active grill shutter module for a period of time." Immediately following this warning, the engine experienced a severe loss of power, followed by loud metallic banging from the engine bay. The vehicle stalled completely and lost all motive power, creating an imminent highway safety hazard.The Physical Damage: Subsequent mechanical teardown by the dealership revealed terminal block destruction, including deep vertical cylinder wall scoring, heavy unburnt liquid gasoline residue in the engine oil pan, and a blown head gasket.Relationship to Active Safety Defect: This catastrophic engine failure mirrors the progressive failure profile of the federal safety agency Campaign 25V455 / Ford Safety Recall 25S75 (Low-Pressure Fuel Pump Failure). In this EcoBoost architecture, the Active Grill Shutter (AGS) module shares critical voltage paths, grounding blocks, and wiring looms with the engine management and fuel delivery systems. The sudden network communication loss is diagnostic proof of a severe voltage drop or electrical short caused by the high-friction fuel pump degradation detailed in Recall 25S75. This circuit failure instantly starved the engine of fuel under turbo boost, inducing an extreme lean-out condition. The resulting pre-ignition forces violently shattered the internal piston rings (the loud banging), which then gouged the cylinder walls, wiped out compression, fouled the crankcase with fuel residue, and blew the head gasket.Request for Action: Ford's current VIN parameters for Recall 25S75 have not yet captured my specific vehicle despite it matching the exact production window, component setup, and catastrophic failure sequence. I am requesting that the federal safety agency log this case as definitive evidence of consequential engine destruction originating from the 25V455 fue

My bronco started having issues randomly when it went into limp mode one day. I brought it in to get fixed and it continued to happen. Ultimately, they told me that it needed a brand new engine.

Once the vehicle hit around 3000 miles it started making a loud clicking noise while the vehicle was running parked or driving . The noise continued to get louder. When I called New Brighton Ford where i purchased the vehicle brand new on 4/25/23 at the end of June I was told to make a service appt. The soonest they could see the vehicle was 4 weeks later. Because of the continued noise I called on about July 12 2023 they agreed they would look at it upon looking at the vehicle. It was found that the engine was in engine failure. They kept the vehicle for six weeks and had to replace to the engine.

Engine failure with 25 miles on the odometer. The dealer inspected it and reported that a piston broke and it needs a new engine. A low engine oil pressure warning came on and the check engine light.
