While driving, the vehicle suddenly lost engine power (it shut off) and displayed "auto start stop shift to P, then restart engine". The vehicle has never done this before, and thank goodness my wife did not have the kids in the car at the time. She was able to pull over safely only because she was on a small road with light traffic, and not at highway speed. Clearly, this put not only our vehicle at risk, but others as the brakes and steering became very hard to use when the engine just shut off out of nowhere. Since it happened today, I have not taken it in to be inspected as of yet. Upon my wife getting the car restarted she came the few miles straight home, where I did test the battery and it read good at 12.57 volts with the engine and accessories off. So the Motorcraft battery is good and as such should not be a cause in this case. To say the least, we have now lost confidence in this vehicle as being a safe mode of transportation.

Ford Motor Company, a massive automotive manufacturer, sold a vehicle with a known, systemic defect that can cause a driver to suddenly lose power steering at highway speeds, while simultaneously disabling critical safety systems ABS and AdvanceTrac stability control. The vehicle's dashboard lights up like a Christmas tree, steering suddenly becomes incredibly heavy, and the safety nets designed to prevent a rollover or spin-out turn off at the exact same moment. Lives are absolutely being put at risk. Because Ford has chosen to handle this through expensive, individual part replacements rather than a massive federal recall, the burden of safety has been unfairly shifted onto the consumer. When the PSCM (Power Steering Control Module) lost communication, it simultaneously disabled my ABS and Traction Control systems. This caused a sudden, unexpected loss of critical safety and handling systems while driving, creating an immediate crash hazard. I have already fixed the vehicle, so I must log the failure. Ford’s network architecture turns a single component failure into a massive, vehicle-wide electrical blackout. I've analyzed the underlying mechanics, and it became clear why this specific cycle is happening and why it causes the entire dashboard to go haywire. The Ford does not use simple independent wires for different parts; it relies on a High-Speed Controller Area Network (HS-CAN). Think of this like a high-speed internet data rail that loops through the car, where the Power Steering Control Module (PSCM), the Anti-Lock Brake System (ABS), the Powertrain Control Module (PCM), and the Body Control Module (BCM) all "talk" to each other in real time. The steering gear houses the internal Steering Angle Sensor. The ABS module needs to know my exact steering angle dynamically to calculate how to apply the brakes or handle stability control (AdvanceTrac).

Sudden Loss of Power Steering Assistance and Simultaneous ABS/AdvanceTrac System Faults I am submitting this complaint to document a serious vehicle safety incident involving my 2014 Ford Fusion SE. The vehicle experienced a loss of communication with the Power Steering Control Module (PSCM), accompanied by faults affecting the ABS and traction/stability control systems. During the incident, the dashboard illuminated multiple warning lights, and the steering suddenly became extremely difficult to operate. The simultaneous loss of power steering assistance and warnings involving critical vehicle safety systems created a serious potential crash hazard, particularly at highway speeds or during an emergency maneuver. Diagnostic scanning with FORScan revealed the following communication-related diagnostic trouble codes: • U0131 — Lost Communication with Power Steering Control Module. • U0121 — Lost Communication with Anti-Lock Brake System (ABS) Module. • U0420 / U0415 — Invalid or implausible data received, as indicated by the recorded codes. I am concerned that an electrical, electronic, or component-level failure involving the power steering system may be associated with the simultaneous faults in other vehicle systems. I request that the federal safety agency review the incident and determine whether similar complaints involving the 2014 Ford Fusion SE indicate a broader safety concern. One concern is that the failure is intermittent. The steering and warning lights appear to recover after the vehicle is shut off, allowed to cool, or restarted. Such intermittent behavior make the problem difficult to reproduce and diagnose, even though the underlying safety concern remain.

The contact owns a 2011 Ford Fusion. The contact stated that while driving at an undisclosed speed, the vehicle suddenly lost power steering assist, nearly causing the contact to lose steering control as the steering locked up, and an audible warning chime sounded. The contact safely maintained control of the vehicle and observed that a power steering warning light was illuminated. The contact associated the failure with the federal safety agency Campaign Number: 15V340000 (Steering); however, the VIN was not included in the recall. The vehicle was towed to the residence. The manufacturer was notified of the failure. The failure mileage was 100,000.

My mom’s 2011 Ford Fusion SEL experienced a loss of electric power steering assistance. I cannot determine the exact moment the failure occurred. When I started the vehicle and attempted to drive away, I noticed that the steering wheel was extremely stiff. The dashboard displayed a “Power Steering Assist Fault” warning. The steering assistance has not returned, including after replacing the vehicle’s battery. I diagnosed the vehicle using FORScan, which identified the following diagnostic trouble codes in the Power Steering Control Module (PSCM): U3000:96-C8 — Control Module, Component Internal Failure. C200C:2F-48 — Steering Shaft Torque Sensor 2, Signal Erratic. Both codes were recorded as previously set and not present at the time of the diagnostic request. However, the power steering warning remains displayed and the steering wheel remains extremely difficult to turn with the engine running. This vehicle was previously included in Ford Safety Recall 15S18 / the federal safety agency Recall 15V340, addressing loss of electric power steering assistance. Ford confirmed that the recall was completed in 2015 through reprogramming the Power Steering Control Module only rather than replacing the steering gear. The current diagnostic codes are specifically identified in Ford’s original recall service instructions as codes associated with steering gear replacement under the recall procedure. I contacted Ford customer service regarding the recurrence of loss of steering assistance. Ford opened a case for internal review but did not confirm repair coverage or provide a decision timeline. I am reporting this because the vehicle has lost power steering assistance despite having previously received the recall remedy. I am concerned that the original safety-related condition may not have been permanently resolved.

My 2018 Ford Fusion suffered a sudden and complete engine failure caused by internal coolant intrusion — coolant leaking into the cylinders and destroying the engine. Pep Boys diagnosed that the failure developed internally over time and could not have been avoided by the owner. This is a known Ford factory defect in the 2.0L EcoBoost engine, documented in Ford's own publications (SSM 47204, SSM 47462, TSB 19-2346, TSB 22-2229), all of which cover the 2018 Fusion. The root cause is Ford's open-deck engine-block design, which allows coolant intrusion and cracking between cylinders. Ford corrected the design in 2019 production. A federal class action (Nelson et al. v. Ford, E.D. California) and the federal safety agency defect petition DP26008 concern this same defect. The sudden loss of engine power created an unsafe driving condition. My warranty claim was denied based on a 'blown head gasket' finding, which is the symptom of the factory defect, not the cause.

Capital Ford of Wilmington diagnosed my vehicle with coolant intrusion into cylinder 2, accompanied by diagnostic trouble codes P0302 and P0316, after check engine light came on. I have been advised that the vehicle requires a complete engine replacement, with an estimated cost of $13,180.89. The vehicle has experienced sputtering and hesitation, creating concern that it could lose power or stall. These symptoms are concerning. After researching this issue, I have learned that coolant intrusion is a documented problem associated with certain Ford vehicles equipped with the 1.5L EcoBoost engine produced during the 2017–2019 period. Ford has addressed this issue through Technical Service Bulletins and Customer Satisfaction Program 21N12. I contacted Ford and was told that my VIN is not covered under the Customer Satisfaction Program. When asked why mine was not covered but other were , Ford stated that even if it is the same issue that is being recalled if my VIN is not flagged it will not be covered for any recall or assistance.I called Ford when I first purchase vehicle and asked about this recall and was told if I didn't have anything wrong with my car and no engine lights that my car was fine and to bring it in if I have any issues.

We purchased this 2017 Ford Fusion 1.5L EcoBoost in August 2022 at 48,968 miles. At 55,940 miles, the vehicle developed a documented coolant leak requiring water-pump replacement. At approximately 75,520 miles, the coolant level was again documented as requiring attention. At approximately 84,189 miles, the vehicle experienced low coolant, low oil, white/gray smoke and rough running. Manteca Ford identified Ford TSB 22-2322 and ultimately performed a major short-block replacement. Despite this major engine repair, mechanical and drivability problems continued. At approximately 101,375 miles, we returned the vehicle to Manteca Ford specifically for loss of power and hesitation. The Ford technician verified a “noticeable loss of power” and lack of full boost. Manteca Ford diagnosed and replaced the turbocharger. The problem was not resolved. Only approximately 205 miles later, at 101,580 miles, the vehicle returned to Manteca Ford because it was still hesitating during acceleration. Manteca Ford then identified DTCs P0729, P07AA, P2703 and P2704 and documented “TRANSMISSION INTERNAL MECHANICAL FAULTS,” including an incorrect sixth-gear ratio and friction-element faults. The dealer recommended replacement or teardown of the transmission. We are extremely concerned about the safety implications of this history. Loss of power and hesitation during acceleration can create a serious hazard when merging onto a highway, entering or crossing traffic, or attempting to accelerate to avoid a collision. This vehicle has experienced repeated engine/powertrain problems despite major repairs, and we are concerned the transmission condition may have been developing during the earlier loss-of-power/hesitation complaints. We request that the federal safety agency evaluate this history for a potential safety-related defect or broader pattern.
