Can I drive with an electric power steering light on?
You can often drive to reach a safe place, but you should not rely on power steering while the warning is on. The EPS light signals a fault in the steering-assist system, which can lead to heavier steering or, in some cases, a loss of assist. Have the vehicle inspected promptly to restore full steering safety.
What the EPS warning light means
Electric power steering (EPS) uses an electric motor to provide steering assist. The warning light signals that the car’s fault-detection system has detected a problem with the EPS components, such as sensors, the motor, wiring, or the control module. Depending on the fault, the system may reduce or disable steering assist, meaning the steering will require more effort, especially at low speeds.
How EPS works
EPS relies on sensors that track steering input and vehicle speed, a control module that calculates the required assist, and an electric motor that provides that assist. When any part of this chain fails or communicates incorrectly, the system can trigger a warning and reduce or remove assist to protect the driver.
Safety implications and driving considerations
When the EPS light is illuminated, steering effort may be noticeably heavier, particularly during parking maneuvers or at low speeds. In some cases, the system may switch to a fail-safe mode with limited or no assist. This can catch drivers off guard, increasing the risk of loss-of-control in emergencies or during sudden maneuvers. If you notice the wheel becoming unusually stiff, or if the vehicle pulls or vibrates while steering, treat it as a warning and seek service promptly.
What to do if the light comes on
The following steps help you handle the situation safely and efficiently.
- Slow down, scan your surroundings, and pull over to a safe location if you can do so safely.
- Turn the engine off and on again to see if the light clears, but do not drive aggressively to test the system.
- Check for additional warning messages or icons on the dashboard that could indicate a related fault.
- Consult your owner's manual for model-specific guidance, and avoid driving long distances if the light persists.
- If steering feels heavy or unpredictable, arrange roadside assistance and tow the vehicle to a qualified repair facility rather than continuing to drive.
Operating with an EPS fault is not recommended for extended trips. The goal is to diagnose and repair the system promptly to restore full steering safety.
What to expect at the repair shop
Mechanics will diagnose the EPS system using onboard diagnostics and a physical inspection of components.
- Diagnostic scan to read fault codes and confirm EPS status.
- Inspection of the EPS motor, steering column sensors, wiring, and fuses for damage or wear.
- Software updates or recalibration of the steering control module if needed.
- Repairs or part replacements for faulty components (sensor, motor, wiring) as indicated by the diagnosis.
- Road test to verify that steering assist is restored and the warning does not reappear.
Repair timelines vary by fault, availability of parts, and the vehicle model. Some issues may be resolved quickly, while others require more extensive service.
Bottom line
The EPS warning light signals a fault in the steering-assist system that may reduce or disable steering assist. You can often drive a short distance to reach a safe location, but you should not rely on the system for normal driving. Seek professional diagnosis and repair promptly to ensure reliable steering performance in all conditions.
Summary
Electrically powered steering is a safety-critical system. A warning light should be treated as an urgent prompt to have the vehicle inspected by a qualified technician. While not necessarily an immediate, life-threatening danger in every case, driving with a persistent EPS fault can compromise steering control, especially in emergencies or complex driving situations. Get the issue diagnosed and repaired to restore full steering safety.
How long can I drive with the power steering light on?
You should not drive for long with the power steering light on; pull over to a safe location as soon as possible. Continuing to drive can be difficult and dangerous because steering will be much harder, especially at low speeds, and a complete system failure could cause the drive belt to break, disabling other critical components like the alternator and water pump. The safest option is to have a qualified mechanic diagnose and repair the problem before driving again.
Risks of driving with the power steering light on
- Increased steering effort: Without power assistance, you will have to use significantly more force to turn the steering wheel. This can be especially challenging and potentially dangerous when parking or making low-speed turns.
- Sudden system failure: If the issue is caused by a failing pump or lack of fluid, the system could fail completely.
- Serpentine belt damage: A seized power steering pump can cause the accessory belt to break. This belt also drives other critical components, such as the alternator (which charges the battery) and the water pump (which cools the engine).
- Component damage: Driving with a failing hydraulic system can cause further damage to the pump and other parts.
What to do instead of driving
- Pull over safely: Find a safe spot to pull over immediately. If you must continue to a nearby location, drive very slowly and with extreme caution.
- Check the fluid (if applicable): If you have a hydraulic system, check the power steering fluid level. If it's low, add the correct fluid, and the light may go off. However, this is often a temporary fix if there is a leak.
- Call a tow truck: To prevent further damage and for your own safety, it is best to have the vehicle towed to a mechanic for a proper diagnosis and repair.
Can I drive my car if the electric power steering goes out?
It will be safe to drive; however, you won't have any power assist.
What does it mean when the electric power steering light comes on?
This light, often represented by a steering wheel icon or the letters “EPS” (Electric Power Steering), indicates that there is an issue with your steering system. If your power steering light turns on unexpectedly, it doesn't always mean immediate danger, but it's a sign that your car should be inspected promptly.
Is it safe to drive with an electric power steering light on?
We strongly advise against driving with a power steering warning light, as your car's handling and safety could be compromised.
