While driving on an interstate it was determined that the engine walls over compressed and blew out the sides of the motor of my 2022 Ford Bronco. The Bronco has 67,000 miles on it which shows a clear manufacturer defect. It is available to be inspected as well to confirm. My wife’s and unborn child’s safety was put at risk by losing acceleration and losing control of the vehicle briefly as it began to shake from the engine misfiring. This easily could have caused a serious wreck had more traffic been present at the time. The dealership has not been able to confirm this on other cars. The engine has been inspected by a Ford dealership. There were no warning lamps or messages prior to the failure and only appeared shortly after the engine over-compressed and began to shake.

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 NHTSA 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 NHTSA 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 NHTSA 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 NHTSA log this case as definitive evidence of consequential engine destruction originating from the 25v455 fue.

Car would shut off shortly after using remote start on key fob then display a warning on digital instrument cluster for two days now. It would also show my speed going back and forth from 0 to 1mph while parked.

I have experienced a loss of fuel pressure/engine stall on several occasions. I am not sure of the specific dates yet I had to add one on this form. There has been a recall since July 2025, for which Ford has acknowledged this increases the risk of a crash yet there is still no resolution. This is unacceptable, I have listed the recall numbers below. Manufacturer recall number 25s75 NHTSA recall number 25v455.

While slowly backing into our home garage, the vehicle accelerated brakes were not working and smashed into the side of the house, put the car in drive to move it. It accelerated forward over correcting and drove into our power box and came to a halt. No brakes were working and the wheels/steering locked up.

On Jan 15, 2025. A cold start for the Bronco, putting in reverse, the vehicle lurched back and to the hard right, uncommanded acceleration at a high rate of speed, steering locked up, brakes locked up, tires spinning, engine revving causing the Bronco to smash into the exterior of my home garage area. Then, shifting to drive, the vehicle again lurched, uncommanded acceleration hard to the left now, steering locked up, brakes locked up, tires spinning engine revving traveling 20-30 feet crashing into the electrical box coming to rest on top of it. Numerous faults showing multiple systems malfunctioning causing this incident.

While driving, after a missed downshift that causes engine bogging, the vehicle experiences a loss of engine power. The engine remains running but will not produce usable torque and will not rev above approximately 800 rpm, despite clutch disengagement and selecting the correct gear. Holding the clutch fully depressed does not immediately restore power; instead, after approximately 4 seconds, the engine stalls or cycles/resets, after which normal operation resumes. The condition persists until the vehicle nearly stops, the engine stalls, or the ignition is cycled. This has occurred in traffic and adverse weather conditions and is repeatable. ”.

A safety recall was issued on the vehicle with no remedy. The recall was in reference to the engine intake valves and stated; "the engine intake valves may crack and break, which could result in loss of motive power and increase the risk of a crash". It also stated, " prior to losing motive power, an engine malfunction indicator lamp may illuminate in the cluster and the driver may notice that the vehicle is running rough". This issue was the result of Ford manufacturing using a material that had "hardness issues". This all came out prior to the vehicle reaching the end of its warranty mileage. A test was required on the engine at the dealership at which time, the technician determined there was no need to perform the "recall test" (confirmed by video sent to us). On or around Dec. 17th, while my wife was driving the vehicle and entering a gas station, the check engine light came on, and the vehicle began losing power. She parked and immediately contacted the Ford dealership. They advised her to not drive the vehicle and have it towed to the nearest dealership (she was in pennsylvania picking up our daughter from college). It was determined by the dealership in PA. That compression in a cylinder was down 5% and the vehicle needed a new engine. We had the vehicle towed back to virginia and inspected by the dealership who services the vehicle. Parts of the engine were removed for visual inspection at which time a crack intake valve was found, confirming the engine was no good. Also, confirming the issue Ford had stated in its recall. All information and pictures were sent to Ford manufacturing for determination on fixing the problem. Ford has said they will not cover the total cost to make good on their recall because the vehicle was out of warranty (miles were exceeded). How are consumers protected from manufactures taking advantage of mileage? the safety recall was issued long before the warranty ran out. What if my wife had crashed w/ our daughter?.

Check engine light stayed on, constant. Code run showed cylinder 4 misfire. Bronco still under warranty so took to dealership. Mechanic said coolant was inside cylinder so he requested recommended remedy from Ford and would probably be engine replacement.

Ford has 3 safety recalls on 2021 Ford Bronco and they have no remedy to fix any of them yet. My car stalled out 3 times now because of the low pressure fuel pump failure recall. I was pulling out into traffic and it stalled out while a car was coming at me. The only solution Ford had was to put old parts in the car which I refused. I asked for a loaner vehicle and they said they don’t have any. Recall warning is going on 6 months. I am at a risk and other people are at a risk having my car on the road, tried lemon law and Ford denied me. Nobody feels safe in my car and someone is going to get seriously hurt if this happens at the wrong time.

The failure appears to have originated in the passenger side engine compartment, but the exact component or system (fuel, electrical, or other) is unknown. The vehicle is a total loss from the fire but should be available for inspection at the tow or storage facility. Our safety and the safety of others were put at risk because the vehicle caught fire suddenly while driving with traffic on a public road; my wife was driving, I was in the passenger seat, and our dog was in the back, and if we had not noticed the smoke and pulled over, the fire could have led to loss of control, injury, or a larger fire. The problem has not been reproduced or confirmed by a dealer or independent service center because the vehicle is completely burned and not drivable. As of now, the vehicle has not yet been inspected by the manufacturer; a claim has been initiated with my insurance company, and I expect their representatives and/or a fire investigator to inspect the vehicle, and local emergency services responded to the scene. There were no warning lamps or messages on the dashboard prior to the fire; the only prior symptom was an abnormal odor from the exhaust that smelled like mothballs or ammonia, first noticed immediately after starting the vehicle at the beginning of the trip on November 23, 2025, followed later in the trip by smoke and then the fire.

I was driving the vehicle on high mountain pass roads in colorado. Anytime I would approach approximately 11,400 feet of elevation. The vehicle would instantly lose all power with no warning lights of any kind. All gauges were in the normal operating range. Vehicle would barely move 2 mph. Created a very unsafe condition on narrow steep dirt roads in the mountains. As soon as I turned around and descended approximately 100 feet in elevation the power came back instantly and vehicle operated normally. This happened on three occasions. The roads we were on were narrow, off-road vehicle mountain roads, and it created an extremely dangerous situation. I contacted Ford and they have not heard of this issue and there are no recalls associated with it. I spoke to a Ford Bronco ambassador, who was also on the trail system with a lot of other off-road vehicles, including Broncos and they had never heard of this happening . This vehicle is six months old. Ford says there are no codes set on my computer and since they cannot duplicate this where I live in phoenix because there are no roads high enough I don’t know where to turn.

Engine started stalking and acting like it wasn’t getting enough gas about a month ago. Took to a dealership and they said u had a cracked file injector line. They supposedly fixed the issue. Today it started stalling again and shut off in the middle of the highway and wouldn’t crank back up. Tried jumping battery and it would turn over but acted like it wasn’t getting any gas when trying to give gas and take off then it would shut off again. Had to get a tow back to dealer ship.

I am not sure why there’s not a remedy. I hope there is soon. Please tell me what can be done as soon as possible.

Component or system that failed or malfunctioned: the fuel delivery system, specifically the fuel pump, which is subject to an active safety recall. The recall states that fuel pump failure can result in loss of fuel pressure and flow, leading to engine stall. The vehicle is available for inspection upon request. How safety was put at risk: a sudden engine stall while driving would result in an immediate loss of propulsion and power, creating a significant risk of collision, particularly at highway speeds or in traffic. This creates a dangerous situation for the driver, passengers, and surrounding vehicles due to the inability to accelerate or maintain speed. Has the problem been reproduced or confirmed by a dealer or service center: the defect has been confirmed by the manufacturer through an official safety recall. At this time, there is no repair remedy available. The vehicle has not yet been repaired due to lack of an available fix. Has the vehicle or component been inspected: the vehicle has not yet been physically inspected for this specific failure because the recall remedy is not available. The defect has been acknowledged by the manufacturer as part of the active recall. Warning lamps, messages, or symptoms prior to failure: at this time, there is no warning indicating when or if the fuel pump may fail. The recall states the failure may occur without warning. No prior warning lamps or messages have reliably indicated when the failure could occur. Additional information: due to the nature of this defect and the lack of an available repair, I no longer feel the vehicle is safe to operate. The uncertainty of a sudden engine stall has created ongoing safety concerns and financial hardship, as I am responsible for a vehicle that may fail without warning.

I purchased this vehicle in may this year and in July the manufacturer issued a safety recall notice. The manufacturer mentions in the recall that the engine may fail and can lead to crashes. I am unbale to use the vehicle for business, since I received the notice and it is causing me a lot to the verge of collapsing my business. I would like the manufacturer to look into this and issue a remedy as quickly as possible as the financial strain on my business is enormous. Thank you!.
