Electric power steering has replaced the old hydraulic setup in most modern vehicles. Instead of relying on fluid and pumps, it uses sensors and an electric motor to adjust steering effort. When it fails, the wheel can suddenly feel heavy or unresponsive. Fixing it quickly prevents further damage and keeps steering safe and predictable.
Average Cost to Repair or Replace Electric Power Steering
Repair costs vary based on which component fails—the motor, the control module, or the steering rack itself. On average, repairs range from $500 to $2,000, depending on your vehicle and labor rates.
- Electric steering rack replacement: $1,200–$2,000
- Power steering motor or module: $300–$1,000
- Basic electrical or sensor repair: $150–$500
Luxury models or vehicles with advanced driver-assist systems fall on the higher end of the range.
Common Signs of Electric Power Steering Failure
A failing system often starts with subtle changes in steering feel.
- Steering wheel feels stiff or heavy, especially at low speeds
- The power steering warning light appears on the dashboard
- Steering assist cuts out intermittently
- Whining or clicking noises when turning
- Uneven steering response between left and right turns
These symptoms point to issues with the electronic control unit, wiring, or torque sensor. If ignored, the system may lose all power assist, forcing the driver to steer manually.
Why Electric Power Steering Fails
Unlike hydraulic systems that leak or lose pressure, electric steering issues come from electrical faults or component wear.
Common causes include:
- Damaged wiring or poor ground connections
- Failing torque or angle sensors
- Burned-out steering motor
- Faulty control module or software glitch
- Water intrusion or corrosion in connectors
In some cases, a software update or recalibration can fix the problem without replacing hardware.
Troubleshooting and Diagnosis
Testing electric power steering requires specialized tools. A mechanic connects a diagnostic scanner to read fault codes from the steering control module. Common error codes reveal whether the fault lies in the motor, sensor, or communication network.
Once identified, repairs may involve cleaning connectors, replacing sensors, or programming a new control module. If the rack or motor assembly is damaged, replacement becomes the only option.
DIY vs. Professional Repair
Electric power steering systems involve high-voltage circuits and integrated electronics. Unlike replacing a belt or topping off fluid, these systems require precise calibration after repair.
DIY difficulty: High
Recommended: Professional service
Only experienced technicians with proper scan tools should handle steering recalibration. Incorrect installation can cause steering drift or disable safety features like lane-keep assist.
Cost by Vehicle Type
| Vehicle Type | Common Repair | Estimated Cost |
| Compact car | Control module replacement | $500–$1,000 |
| Midsize sedan | Steering motor or sensor | $700–$1,400 |
| SUV or truck | Full steering rack replacement | $1,500–$2,000 |
| Luxury or electric vehicle | Rack with assist motor | $1,800–$2,500 |
These estimates include parts and labor but can shift with regional rates or manufacturer design complexity.
Can You Drive with Electric Power Steering Problems?
The vehicle will still steer, but effort increases dramatically, especially at low speeds. Driving like this puts stress on suspension components and risks complete assist loss mid-turn. It’s safer to schedule service immediately once the warning light appears.
Preventing Future Repairs
Electric steering systems require little maintenance, but preventive habits help extend life.
- Avoid deep water or heavy splashes that reach connectors.
- Keep the battery and charging system healthy. Low-voltage strains steering electronics.
- Listen for new noises or changes in steering effort and address them early.
- Schedule regular diagnostic scans during major services.
A clean electrical system keeps sensors reading correctly and steering assist consistent.
When to Replace Instead of Repair
If your vehicle has over 100,000 miles and the steering rack or motor fails, full replacement often makes more sense than piecemeal fixes. Replacing the assembly restores both steering feel and re
How much does it cost to fix electric power steering?
Repairs range from $500 to $2,000, depending on the part and vehicle type.
What causes electric power steering to fail?
Common issues include sensor failure, wiring damage, or faulty control modules.
Can I repair it myself?
No. These systems require calibration and professional diagnostic tools.
Does every car have the same system?
No. Each manufacturer uses unique designs and software, which affect repair cost and time.
How can I avoid future issues?
Keep the electrical system healthy, inspect connectors for corrosion, and respond quickly to warning lights.
