Modern vehicles are designed with a host of dashboard warning lights to alert drivers of potential problems. The steering wheel light is one of them that frequently sparks curiosity. This warning symbol, typically resembling a steering wheel with an exclamation mark or accompanied by the letters “EPS” or “EPAS,” is an important indicator that something may be wrong with your vehicle’s steering system. But what exactly does it mean?
In this post, we’ll explore what the steering wheel light signifies, why it might come on, and what steps you should take if you see it illuminate on your dashboard.
What Does a Steering Wheel Light Mean? Understanding the Warning Sign on Your Dashboard
What is the Steering Wheel Light?
One component of your car’s onboard diagnostics system is the steering wheel warning light. It usually appears in red or yellow (amber), depending on the severity of the issue. The light often looks like a simple steering wheel icon and may be accompanied by an exclamation mark or other indicator symbols. This light is directly related to the power steering system, particularly electric power steering (EPS) in newer vehicles.
When this light comes on, it’s alerting you to a malfunction within the steering system — and this is not something to ignore.
Common Reasons the Steering Wheel Light Comes On
Here are several potential causes for the steering wheel warning light to illuminate:
1. Electric Power Steering (EPS) Failure
Most modern cars use electric power steering instead of traditional hydraulic systems. The steering wheel warning light is activated if the EPS system detects a malfunction. A failure in this system might make steering feel very heavy or unresponsive.
2. Low Power Steering Fluid (in older systems)
If your car uses a hydraulic steering system, low power steering fluid levels can cause issues. While EPS doesn’t use fluid, some older vehicles still rely on hydraulic fluid, and a leak or drop in fluid can lead to a warning light.
3. Sensor Issues
Modern steering systems include a variety of sensors, including steering control modules, torque sensors, and angle sensors. If one of these sensors fails or sends incorrect data, the light may come on.
4. Battery or Electrical Problems
Since EPS systems are electronic, any issue with the car’s battery or electrical system could affect the power steering. A weak battery or failing alternator may not provide enough power to the steering motor, causing the light to turn on.
5. Software Glitches
Occasionally, the steering warning light may be triggered by a software error or a temporary glitch in the vehicle’s onboard computer. This is more common in newer, tech-heavy cars and may require a reset or software update.

What To Do When the Steering Wheel Light Comes On
The best course of action depends on how your vehicle is handling when the light appears:
🚨 If the steering feels challenging and the light is red:
This indicates a serious issue. Your steering system may be failing or has failed already, making it unsafe to continue driving. Make a safe stop and request roadside help.
⚠️ If the light is yellow but the car drives normally:
You may still have some power assistance, but the system is compromised. Making a service appointment as soon as feasible is crucial. Continuing to drive long distances in this state could worsen the problem.
Can I Drive with the Steering Warning Light On?
Technically, yes — but you shouldn’t. It can be risky to drive while your power steering is impaired. Your ability to control the vehicle — especially at low speeds or during emergency maneuvers — could be affected. If the steering becomes too stiff, it could lead to a loss of control.
Additionally, ignoring this light can lead to more expensive repairs. What might be a minor electrical issue today could turn into a major steering system failure tomorrow.
Conclusion
The steering wheel warning light is your vehicle’s way of saying, “Pay attention — something’s wrong with your steering system.” Whether it’s an electrical fault, a fluid issue, or a failing sensor, it’s important to take the light seriously. Prompt action can prevent further damage and keep you safe on the road.
If this light ever comes on, don’t wait. As soon as you can, have a skilled mechanic examine your car. It might be a quick fix, but left unresolved, it could put both your safety and your wallet at risk.
