In most cases, you should not drive with a failed power steering system; pull over safely and arrange towing to a repair facility. This is essential for your safety and for the safety of others on the road.
Power steering makes it easier to steer, especially at low speeds and during parking. When the system fails, steering can become heavy, unpredictable, or even completely unassisted. Modern vehicles use either hydraulic power steering (HPS) or electric power steering (EPS). Problems can arise from low fluid levels or leaks, worn belts, electrical faults, or software glitches in EPS. A failure increases the risk of a crash, so address the problem promptly and through a qualified repair shop.
What power steering is and how it can fail
Understanding how the system works helps you recognize when to seek help.
Hydraulic power steering relies on a belt-driven pump that circulates fluid to assist steering. Electric power steering uses sensors, a motor, and a control module to provide assist. Both systems can fail due to wear, leaks, a broken belt, or electrical/software faults. Dashboard warning lights for power steering or EPS often signal an issue that should be diagnosed by a professional.
Signs of a power steering problem
Look for these common indicators that your steering assist is not functioning normally:
- Heavy or stiff steering, especially at low speeds
- Loss of steering assist or a completely hard steering wheel
- Warning lights for power steering or EPS on the dashboard
- Fluid leaks, unusual smells, or noises from the engine bay
- Unusual steering feel, such as binding, vibrating, or jerky movement
- Sudden changes in steering response in EPS-equipped vehicles
If you notice any of these signs, treat them as a signal to stop driving as safely as possible and seek service promptly.
What to do if you experience a failure
Follow these steps to protect yourself and others while you address the problem.
- Slow down gradually and signal early to move to the shoulder or a safe area
- Find a safe place to stop, turn on hazard lights, and remain calm
- Do not continue driving long distances; arrange roadside assistance or a tow to a repair shop
- If you must move a short distance to reach safety, do so very slowly and keep both hands on the wheel
- After stopping, check for obvious causes such as low hydraulic fluid or a broken belt if it is safe to inspect
These actions reduce the risk of losing control while you plan the next steps and arrange professional inspection and repair.
What to check after a stop and how to get it fixed
When it is safe to do so, consider the following checks and actions to prepare for repair or towing.
- Check for visible leaks or a low fluid level in hydraulic PS systems; do not drive with a low fluid level
- Inspect the drive belt for cracks or wear if it is accessible
- Note any dashboard warning lights and when they appeared
- Consult the owner’s manual for any EPS reset procedures and recommended service intervals
- Arrange towing or service with a qualified mechanic or dealership if the issue persists or cannot be reset
Do not attempt a drive to a service center if the issue persists, as continued operation could lead to a loss of steering control.
Is there a difference depending on the system?
Yes. A hydraulic system failure typically results in noticeably heavier steering and requires fluid level checks and potential belt replacement. An EPS fault may trigger additional warning lights and could require software updates or module replacement. Regardless of system type, a persistent or recurring failure should be repaired promptly to restore safe steering.
Summary
Power steering failure is a serious safety concern. Do not ignore warning signs or assume you can manage with reduced assist. If you experience heavy steering, warning lights, or other indicators of a problem, ease to a safe location and arrange professional repair or towing. Safe driving relies on functional steering, and timely maintenance is essential to return the vehicle to reliable operation.
