The issue most often shows up as a sudden or intermittent loss of electric power steering (EPAS) assist, making steering feel heavy or unresponsive. The underlying problem is usually within the EPAS system—its electric motor, control module, or related wiring—rather than a traditional hydraulic pump failure.
For drivers of the 2013 Ford Edge, understanding EPAS and how it can fail helps explain why steering becomes more effortful, especially at low speeds, and why warning messages may appear on the instrument cluster. This article outlines what EPAS is, common symptoms, likely causes, and what to do if you experience problems.
Understanding the EPAS system in the Edge
Electric Power Assisted Steering (EPAS) uses an electric motor and a steering torque sensor to provide steering assist. The system is controlled by a steering module and sensors rather than a hydraulic pump driven by the engine. When the EPAS system detects a fault, it may reduce or cut off assist to protect the vehicle and inform the driver with a warning message.
How EPAS differs from hydraulic steering
Hydraulic power steering relies on a belt-driven pump and fluid pressure, which can fail due to leaks or pump wear. EPAS relies on electronics and a motor, which means failures often involve sensors, wiring, or the motor itself rather than fluid components. This shift changes the failure modes and the kinds of repairs that are typically needed.
Common symptoms of EPAS problems
Before a repair is made, several telltale signs often appear. The list below summarizes frequent experiences reported by Edge owners and service technicians.
- Loss of steering assist or noticeably heavier steering, particularly at low speeds.
- Warning message on the gauge cluster, such as “Power Steering Assist Fault” or “Service Power Steering Now.”
- Unusual noises (whining, grinding, or tapping) coming from the steering area when turning.
- Intermittent or persistent steering feel that changes, often improving after restarting the vehicle.
- Steering feel that is inconsistent or jerky, with reduced precision.
These symptoms can occur suddenly or appear intermittently, and they may be more noticeable when the vehicle is cold or battery voltage is low.
Causes and diagnostic steps
Several factors can trigger EPAS faults. The following list outlines common culprits and how technicians typically diagnose them.
- Faulty EPAS motor or control module
- Torque sensor failure or miscalibration within the steering column
- Wiring harness damage or poor connections around the EPAS unit
- Low electrical voltage due to weak or failing battery/charging system
- Software/firmware needing an update or reprogramming of the EPAS system
- Moisture, corrosion, or physical damage to EPAS components in some cases
Diagnosing the issue typically involves scanning for fault codes with a professional diagnostic tool, inspecting electrical connections, checking battery voltage, testing the EPAS motor and torque sensor, and applying any necessary software updates or component replacements.
What owners can do and potential fixes
Owners dealing with EPAS symptoms should take appropriate steps to ensure safety and address the root cause. The fixes range from software updates to hardware replacements, depending on the diagnosis.
- Have the vehicle diagnosed by a trained technician or Ford dealer to confirm an EPAS fault and read the fault codes.
- Try a software update or reprogramming for the EPAS control module, as some faults are resolved with updated calibration.
- Inspect and repair or replace damaged wiring harnesses or connectors tied to the EPAS unit.
- Replace the EPAS motor or control module if the fault is motor- or module-related.
- Check the battery and charging system; ensure the system provides stable voltage to the EPAS unit.
- In severe cases, replacement of steering rack or column components may be necessary, though this is less common.
Costs vary widely depending on the component and whether the vehicle is under warranty or covered by a recall. Typical EPAS-related repairs at a dealership can range from software updates (lower cost) to several hundred to over a thousand dollars for motor or module replacements, plus labor. Aftermarket pricing and independent shops may offer different quotes, so it’s wise to obtain multiple estimates.
Recalls, service bulletins and how to check your VIN
Ford and the NHTSA have issued recalls and service bulletins addressing EPAS issues in some Ford vehicles, including Edge models from around this era. Because EPAS faults can arise from several root causes, the specific remedy and whether a repair is covered depend on the VIN and the nature of the defect.
- Check recall status for your 2013 Ford Edge by entering your VIN on the National Highway Traffic Safety Administration (NHTSA) recall website or Ford’s official recall portal.
- Ask a Ford dealer or a trusted mechanic to review current Technical Service Bulletins (TSBs) related to EPAS for your exact VIN; these bullets often guide software updates or component replacements.
- If you experience a steering warning or heavy steering, avoid driving aggressively and schedule service promptly to prevent a loss of steering assist while driving.
Remember that recall and TSB eligibility depends on the vehicle’s VIN and production date, so an official lookup is the best way to determine coverage and required fixes.
Summary
For the 2013 Ford Edge, power steering problems most commonly stem from the Electric Power Assisted Steering (EPAS) system. Symptoms include sudden or intermittent loss of steering assist, warning lights, and unusual noises. Causes range from motor or control module faults to wiring issues and software needs. Diagnosis should be performed by a qualified technician, and solutions may involve software updates, wiring repairs, or EPAS component replacement. Always check for recalls and service bulletins relevant to your VIN, and address symptoms promptly to maintain steering safety.
