What is the steering system warning on a Subaru?
The steering system warning in a Subaru is the Power Steering or EPS (electric power steering) warning light, signaling a fault in the steering assist system and prompting service.
In many Subaru models, this warning appears as a steering wheel icon on the instrument cluster, sometimes accompanied by the words "Power Steering" or "Steering." It points to a problem with the EPS system, the vehicle’s battery or electrical system, wiring, or related components, and it can affect steering effort and safety if left unaddressed.
What the warning light means
The warning indicates a fault within the steering system that could reduce or remove steering assist. Understanding the potential causes helps drivers decide how to respond.
Common causes of a steering system warning light in Subaru vehicles include problems with the electric power steering (EPS) system, electrical faults, and, in older models, hydraulic power steering components. The list below outlines the main possibilities.
- Faulty EPS motor or control module
- Low or fluctuating battery voltage affecting the EPS system
- Faulty torque sensor or steering angle sensor
- Damaged or loose wiring, connectors, or a blown fuse related to the EPS system
- Hydraulic power steering failure or leakage in older Subaru models
- Software glitches requiring an ECU update or recalibration
Even if the vehicle seems drivable, a steering warning should be treated seriously. Loss of steering assist can make steering harder and handling less predictable, especially at higher speeds.
What to do if the warning appears
Before taking action, consider the steps below to manage safety and plan service.
- Check for other warning lights (battery, check engine, or brake) to see if there is a broader electrical issue.
- If the light is steady and the steering feel is normal, you may continue to drive cautiously to a repair shop, avoiding high speeds and complex maneuvers.
- If the steering feels heavy, the wheel pulls, or you hear a whine or groan from the steering area, safely pull over and call for assistance.
- Have the vehicle inspected by a Subaru technician as soon as possible; avoid driving long distances with the warning on.
Note: Some issues may require a software update or recalibration of the EPS system, while others may require component replacement. A qualified technician will run diagnostics with Subaru-approved tools to confirm the exact cause and necessary repairs.
Additional notes
Difference between EPS and hydraulic systems
Most current Subaru models use electric power steering (EPS). In older Subarus that relied on hydraulic power steering, warnings may indicate issues with hydraulic fluid level, pump failure, or hose leaks. Regardless of the system type, the warning signals reduced or unsafe steering capability and should be checked promptly.
Summary
The steering system warning on a Subaru signals a fault in the electric power steering system (or, on older models, hydraulic power steering) and can affect steering assist. It is not a problem to ignore. If the warning appears, monitor the vehicle, drive cautiously, and seek service from a Subaru-certified technician to diagnose and repair the root cause, ensuring safe steering performance.

- EPS Motor: If the electronic motor fails, replacement costs typically range from $300 to $800.
- Full Steering Column: Replacing the entire steering column is one of the more expensive repairs, with costs often falling between $530 and $1,550.
- Steering Rack: Replacing the steering rack can cost between $710 and $2,420 for most vehicles.
- Diagnostic Fees: Some shops charge a diagnostic fee, which can be around $200, to determine the exact problem.
Factors that affect the cost
- Vehicle Make and Model: The cost of parts varies significantly based on the vehicle. For example, dealer parts can be more expensive than aftermarket ones.
- Labor Costs: Labor can account for a significant portion of the total cost, especially for complex repairs like a steering column or rack replacement.
- Shop Location: Labor rates vary by geographic location, so getting quotes from different shops can be beneficial.
- Part vs. Labor: In many cases, labor costs can be higher than the price of the part itself.
- DIY vs. Professional: If you have the mechanical skill, doing the work yourself can save significant money on labor. However, professional help is recommended for more complex issues, and some repairs require specialized equipment or programming.
Can I still drive with the power steering light on?
It is not safe to drive with the power steering light on, as it can lead to a complete loss of steering assistance and is a sign of a serious problem. While you may be able to drive, it will be significantly harder to steer, which increases the risk of an accident, especially during emergency maneuvers or low-speed turns. You should pull over to a safe location immediately and have the vehicle inspected by a professional mechanic.

What to do when the light is on
- Pull over to a safe spot: Park your car as soon as it is safe to do so.
- Check the steering fluid: If your car has a hydraulic system, check the power steering fluid level and top it off if it is low. Be aware that a low fluid level often indicates a leak that needs to be fixed.
- Restart the car: For electric power steering (EPS) systems, a simple reset by turning the car off and on may solve the issue. If the light remains on, the problem is more serious.
- Get it inspected: If the light persists or if you have a hydraulic system, do not drive the vehicle further than is necessary to get to a repair shop.
- Avoid high speeds: If you must drive, do so with extreme caution and avoid highways and high speeds.
Why it's dangerous
- Loss of steering assistance: The warning light signals a problem that can make the steering wheel much harder to turn, requiring more physical effort.
- Risk of sudden failure: A hydraulic system can experience sudden failure due to low fluid or a broken pump, making steering impossible.
- Increased accident risk: The difficulty in steering can make it hard to react quickly to obstacles or make sharp turns, increasing the likelihood of a crash.
- Potential for further damage: Driving with a power steering issue can cause further damage to the pump or other components.
How to fix a power steering warning?
5 seconds. Turn the steering wheel to the full left lock position and apply force for approximately. 5 seconds. Return the steering wheel to the straightforward.
What does it mean when the power steering system warning comes on?
A power steering signal, typically a steering wheel icon with an exclamation mark, indicates a problem with your vehicle's power steering system, requiring immediate attention. This can be caused by low power steering fluid in older hydraulic systems or a malfunction in the electronic components (like sensors, wiring, or the motor) in newer electric systems. While the vehicle may still be drivable, steering will be significantly harder, especially at low speeds, so it's recommended to have a mechanic inspect it soon.
What the signal means
- Your power steering system has a fault: The warning light means the vehicle's computer has detected an issue with the power steering system.
- For hydraulic systems: The most common cause is low power steering fluid, often due to a leak. A faulty pump or worn-out belt can also be the cause.
- For electric power steering (EPS): The problem is likely electronic, such as a sensor, wiring, or the electric motor itself.
What to do
- Pull over safely: If the light comes on while you're driving, find a safe place to stop as soon as possible.
- Check your owner's manual: Consult your car's manual to understand the specific warning light and how to check your fluid level.
- Check fluid level (for hydraulic systems): Locate the power steering fluid reservoir (usually marked with a steering wheel symbol) and check the fluid level. If it's low, top it off with the correct fluid as specified in your manual.
- Note that it might be temporary: If you added fluid to a hydraulic system and the light goes off, it could be a short-term fix. A low level indicates a leak that must be repaired to prevent future problems.
- Take it to a mechanic: Even if the light turns off after adding fluid, it's best to have a professional check the system for leaks or other issues. If the light doesn't go out, or if you have an electric system, a mechanic needs to diagnose the problem.
