My 2019 ford mustang egoboost with only 59,000 miles has a cylinder three coolant intrusion. This is disappointing, as the only right way to fix this according to Ford, is to replace the whole engine. Nobody should expect to have to fix their entire engine. Now on cold starts coolant is leaking in to cylinder three, which is causing misfires and could potentially lead to a safety, risk. Ironically, there’s a lawsuit currently in place for this exact problem. This is a problem, sudden engine failure or stalling due to severe coolant intrusion introduces a dangerous loss of power while operating the vehicle at speed and could lead to a blown or locked up motor. Ford has kept this under wraps since the release of this generation of vehicle.

The contact owns a 2024 Ford Mustang. The contact stated that while driving 75 MPH, the vehicle stalled. The contact coasted the vehicle to the side of the road, shifted to park(P) and waited five minutes, and restarted the vehicle. The failure was a recurring failure. Additionally, the vehicle lost windshield washer fluid pump functionality and days later by the check engine warning light illuminated due to a weak or failing battery. The contact associated the failure with the federal safety agency Campaign Number: 26V547000 (Electrical System). The dealer was contacted but was unable to reproduce failure and stated that vehicle needed a software update. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 27,500.

I am filing a formal safety complaint regarding a catastrophic Electronic Power Assisted Steering (EPAS) failure and severe electrical short circuit on my 2015 Ford Mustang. This vehicle is exhibiting hard fault code B137F:09 (Steering Wheel Left Switch Pack: Component Failure / Short to Ground or Open). This electronic failure creates an immediate, severe safety hazard that goes entirely outside the scope of normal vehicle wear and tear. While driving, the vehicle's steering wheel pulls and jerks violently on its own, actively fighting my manual steering inputs. Furthermore, this internal electronic short creates a massive parasitic electrical draw that prevents the vehicle's computer modules from entering sleep mode when turned off. This has resulted in the primary vehicle battery draining completely flat and causing the vehicle to completely shut down, stall, or lose total electrical power altogether. A vehicle that forcefully steers itself away from the intended path of travel and suffers total electrical shutdown is a clear, life-threatening safety risk to myself and others on the road. Ford Motor Company is fully aware of this dangerous defect. They previously issued Safety Recall 15S18 for a very specific, limited batch of early-production 2015 Mustangs experiencing identical EPAS failures, replacing their steering gears for free. For the remaining 2015 Mustang owners experiencing the exact same hazardous failure, Ford quietly shifted the issue over to a Technical Service Bulletin (TSB / SSM 51312). By limiting the scope of Recall 15S18 purely due to the financial cost of a universal recall, Ford has left an entire population of 2015 Mustang owners in direct harm's way. Some owners received a free lifetime safety fix, while the rest of us are being forced to pay thousands of dollars out-of-pocket to correct an identical factory electronic defect. I request that the federal safety agency immediately open an investigation into Ford's handling of the 2015 Mustang EPAS and more.

The contact owns a 2025 Ford Mustang. The contact received notification for the federal safety agency Campaign Number: 26V122000 (Engine and Engine Cooling); however, the part to complete the recall repair was unavailable. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate as intended. The vehicle stalled, jerked forward, and the check engine warning light illuminated. The force of the jerk propelled the contact onto the steering wheel. The vehicle was restarted, and the check engine warning light was no longer illuminated. The vehicle was driven to the residence. The contact stated that the vehicle required several attempts to start on some occasions. A dealer was made aware of the failure but confirmed that the recall remedy was unavailable. The vehicle was not diagnosed or repaired by an independent mechanic or a dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 14,000.

The contact owns a 2018 Ford Mustang. The contact stated that while driving at various speeds, the engine sputtered with the check engine warning light illuminated. There was heavy white smoke coming from the tailpipe. Upon arriving at the destination, the vehicle hesitated to restart, and the contact observed a significant loss of coolant. The vehicle stalled while driving at various speeds. Upon inspection, the dealer confirmed coolant intrusion in cylinders #2 and #3, resulting in total engine failure. The manufacturer was notified of the failure and stated that the VIN was not under recall, and there was no warranty associated with the vehicle. The vehicle was repaired out-of-pocket by the dealer. The failure mileage was approximately 56,000.

My vehicle, VIN [XXX], is subject to the federal safety agency Recall 25V455 (Ford Recall 25S75) involving a defective low-pressure fuel pump that may cause engine hesitation, loss of power, or engine stalling. This recall was announced in July 2025 and remains open on the federal safety agency VIN lookup as of June 2026. More than eleven months have passed since the recall was announced, and Ford has not provided a repair remedy for my vehicle. I believe this is an unreasonable delay for a safety-related defect. In addition, the recall previously appeared in the FordPass application associated with my vehicle but no longer appears there, even though both the federal safety agency and Ford recall website VIN lookup continues to show the recall as open. This discrepancy creates confusion regarding the status of the recall and whether Ford is actively notifying affected owners. I am concerned that my vehicle remains subject to a known safety defect without an available repair and request that the federal safety agency review Ford’s handling of Recall 25V455, the prolonged delay in providing a remedy, and the inconsistency between Ford’s customer-facing systems and the federal safety agency recall database.

1. Component failed and availability for inspection: The engine assembly block failed due to a manufacturing defect known as "coolant intrusion into the cylinders." The vehicle and the defective engine are currently located at my residence and remain fully available for federal or manufacturer inspection upon request. 2. Safety risk: The safety of myself and others was severely compromised. Coolant entering the combustion chambers causes sudden, severe engine misfires across all cylinders, erratic power loss, and instantaneous stalling. Operating a vehicle where the engine can suddenly lose all power on high-speed roads creates an immediate risk of rear-end collisions and catastrophic traffic accidents. Furthermore, high-pressure internal coolant leaks pose an inherent risk of engine fires. 3. Problem confirmed by a dealer: Yes. The problem has been officially diagnosed and confirmed by an authorized Ford dealership service center, which documented internal coolant intrusion. 4. Inspected by manufacturer, police, or insurance: The component was inspected and verified by the vehicle manufacturer's authorized dealership technicians. It has not been inspected by the police or insurance representatives, as no crash has occurred yet. 5. Warning lamps, messages, or symptoms prior to failure: Prior to the diagnosis, the vehicle exhibited a "Check Engine Light." Currently, the vehicle is suffering from critical failure symptoms: the Check Engine Light is flashing constantly, the engine misfire codes are actively showing on all 4 cylinders, and the vehicle shakes violently at low RPMs (rough idling). These severe symptoms first appeared approximately 2 moths ago and have progressively worsened due to the coolant intrusion.

Ford mechanics fix spark plugs, coils, electrical. None of which has fixed the issue of stalling on the highway which poses risk of me the driver and others driving on the highway. The only light that comes on is engine light.
