What is the power steering failure on the Ford Edge?
Power steering failure on the Ford Edge is typically a loss of electric power steering assist (EPAS), turning what is normally a light steering effort into a heavier, less forgiving ride. Here’s what drivers should know about causes, symptoms and proper steps when the system falters.
Understanding EPAS in the Edge
All Ford Edge models use electric power steering (EPAS). The EPS motor and control module adjust steering assist based on vehicle speed and input from the steering wheel. When the EPAS system detects a fault, it may disable assist or trigger warning lights, signaling the need for service. In many cases the issue can be resolved with software updates, sensor or motor replacement, or other repairs performed by a dealer or qualified technician. As with any steering fault, safety is the priority; if in doubt, pull over and seek help.
Causes
Common electrical, mechanical, and software factors can trigger EPAS faults in the Edge.
- Faulty EPS motor or torque sensor
- Damaged or corroded wiring or connectors in the EPAS system
- Low battery voltage or charging system problems affecting the EPS controller
- Faults in the steering column or EPS control unit (ECU)
- Software glitches requiring updates or recalibration
- Mechanical binding or wear in the steering rack or linkages (less common with EPAS-only designs)
Addressing these issues typically requires diagnostic work with Ford's OEM scan tools. Depending on the root cause, solutions can range from a software update to replacement of the EPS motor or related wiring.
Symptoms
Watch for telltale signs that the Edge’s EPAS is malfunctioning.
- Dashboard warning lights such as “Power Steering Assist Fault,” “EPS,” or a general steering system message
- Heavy or stiff steering, especially at low speeds
- Intermittent or permanent loss of steering assist
- Unusual noises from the steering column or EPS module
- Unstable steering feel, wandering or pulling at various speeds
If you notice these symptoms, avoid aggressive steering maneuvers and seek service promptly. A faulty EPS can compromise control, particularly in emergency situations or slippery conditions.
What to Do During a Drive
To reduce risk when EPAS fails on the road, follow these steps.
- Safely pull over to a secure location and turn off the engine; restart to see if the EPS reinitializes.
- Check for warning lights and listen for unusual noises; do not ignore warning indicators.
- If the system remains unresponsive, avoid long trips and arrange roadside assistance or a tow to a Ford dealer or qualified shop.
- Inspect the battery and charging system; a weak battery can affect EPS operation. If the battery is old or failing, replacing it may restore EPS function.
- Have a professional diagnose using OEM scan tools to read EPS-related diagnostic trouble codes and perform necessary recalibration or component replacement.
In many cases, the fix is software-related or involves replacing a failing EPS motor or related wiring harness. Costs and timelines vary by model year and local labor rates.
Recalls, Service Campaigns and Safety Guidance
Ford has issued recalls and service campaigns on EPAS and related steering components for various models, including the Edge and other vehicles that share the platform. If your Edge lights up a steering or EPS warning, or you’ve experienced a steering issue before, check your VIN against the NHTSA recall database or Ford’s recall portal to see if a remedy is available for you. Even without a recall, a confirmed EPAS fault should be addressed promptly to avoid unexpected loss of steering assist.
In addition to recalls, Ford has issued technical service bulletins (TSBs) guiding dealers on diagnostics and software updates for EPAS faults. Your dealer can verify applicable campaigns and advise on the best course of action.
Summary
Power steering failure on the Ford Edge stems from the electric power steering system (EPAS). It presents as reduced or lost steering assist and is flagged by dash warnings. Causes range from motor or sensor faults to wiring and software issues. If you experience symptoms, respond safely, seek professional diagnosis promptly, and check recall databases for any VIN-specific remedies. With timely diagnosis and the appropriate repair, normal steering performance can usually be restored.
