It means your vehicle’s power steering system needs maintenance, which can involve checking or replacing hydraulic fluid in a traditional system or performing software updates and component inspections in an electric power steering (EPS) setup.
Understanding power steering systems
Most cars rely on one of two main types of power steering: hydraulic power steering (HPS), which uses a fluid-filled pump to assist steering, and electric power steering (EPS), which uses an electric motor and sensors to provide assist. HPS systems use a dedicated power steering fluid and may require periodic fluid changes and belt checks. EPS systems rely more on software calibration and electronic components, with fluid changes typically not part of routine service unless the vehicle’s manual specifies otherwise.
What servicing means for hydraulic power steering
When a hydraulic power steering system is being serviced, technicians focus on fluid health, leaks, and mechanical wear that affect steering effort and response.
- Check fluid level and inspect the condition of the reservoir fluid; top up with the correct fluid if needed.
- Inspect for leaks at the pump, hoses, rack, and connections; repair or replace leaking parts as required.
- Inspect the drive belt (serpentine belt) that drives the power steering pump; replace if worn or cracked.
- Flush and replace old or contaminated fluid to purge air and contaminants that can cause whining or stiff steering.
- Test the system for noises, binding, or reduced assist and diagnose potential pump or rack issues if symptoms persist.
- Perform a road test to ensure normal steering feel and confirm there are no warning lights related to the steering system.
In short, hydraulic power steering service centers on keeping the fluid clean and the mechanical components in good condition to preserve smooth, easy steering.
What servicing means for electric power steering
Electric power steering differs because it relies on sensors, motors, and control software rather than fluid. Service typically focuses on electronics, calibration, and software rather than fluid changes.
- Diagnostics for fault codes and sensor/motor functionality using specialized scan tools.
- Software updates or recalibration to restore proper steering assist and torque sensing.
- Inspection of wiring harnesses, connectors, and the EPS motor for corrosion or damage.
- Replacement of faulty EPS components (motor, torque sensor, or control module) if diagnostics indicate.
For EPS, the emphasis is on electronics and software, with fluid changes rarely part of routine service unless the vehicle’s manual specifies otherwise.
When to service
Regular maintenance should follow the manufacturer's recommendations, but most drivers should consider a service if any symptoms appear or if fluids are due for replacement. Common triggers include unusual noises while turning, stiff or heavy steering, visible leaks, a warning light on the dashboard, or a drop in steering performance.
- Whining, groaning, or squealing noises when turning
- Stiff, heavy, or unusually difficult steering, especially at low speeds
- Visible leaks around the pump, hoses, reservoir, or rack
- Low fluid level or fluid that looks dark or smells burnt
- Steering system warning light on the dash
Conclusion: If you notice these signs, have a professional inspect the system promptly to prevent more serious damage and preserve safe handling.
Costs and choosing a shop
Costs vary by system type, vehicle model, and local labor rates. Here are typical ranges and what affects price.
- Hydraulic system service (fluid top-up/flush, belt inspection/replacement, leaks): commonly $100–$300, plus fluid costs
- Component repairs (pump, rack, hoses) can raise total to $400–$1,500 depending on parts and labor
- Electric power steering service or repair (sensors, motor, or software updates): typically $150–$1,000 depending on the part and the job
Conclusion: Get a detailed estimate that includes diagnostic time, parts, labor, and any potential fluid costs, and ensure the shop uses manufacturer-recommended fluids and procedures for your vehicle.
Summary
“Service your power steering” signals that the steering assist system needs attention, whether it’s a hydraulic setup requiring fluid care and leak checks or an EPS setup needing electronics diagnostics and calibration. Regular maintenance, prompt attention to symptoms, and guidance from your vehicle’s manual or a qualified technician help maintain safe handling and prevent costly repairs down the line.
How much does it cost to service power steering?
A typical power steering flush, including labor costs, will run you anywhere from $90 to $125. If you're performing the flush on your own, all you need is the right fluid, which will usually cost around $10. Finding the right fluid presents its own obstacles, however.
Can I drive my car if it says service power steering?
It is not recommended to drive a vehicle with the red power steering warning light on. If the power steering system fails, the car will become difficult to steer, making it potentially dangerous to drive.
How to fix service power steering mean?
How to Fix the Power Steering Warning Light
- Step 1: Check Power Steering Fluid. If your car uses a hydraulic system:
- Step 2: Inspect for Leaks or Damage. Look for fluid pooling under the car.
- Step 3: Use an OBD2 Scanner Like Carista.
Does Grease Monkey change power steering fluid?
Grease Monkey provides fluid exchange services for critical vehicle systems, including engine oil, transmission fluid, coolant (radiator fluid), brake fluid, and power steering fluid.
