If your power steering is broken, you should not continue driving; steering will be heavy and unpredictable, increasing the risk of losing control. The safest option is to pull over safely and arrange roadside assistance or a tow.
Power steering reduces the effort needed to turn the wheel, especially at low speeds or in parking. If that assist fails, you may still steer but with much more force required and reduced responsiveness, which raises the chance of an accident. This article explains how power steering works, what to do in a failure, and how to get back on the road safely.
What power steering does and why failure matters
Power steering aids the driver by multiplying steering input, making it easier to steer the vehicle. There are two main types: hydraulic systems that use a pump driven by the engine and fluid pressure, and electric systems that use an electric motor or assist from the steering rack. When the system fails, steering can become extremely heavy or feel inconsistent, making precise control more difficult especially in tight spaces, at slow speeds, or during emergency maneuvers. Warning lights, unusual noises, or fluid leaks can indicate a problem that needs attention.
Hydraulic power steering systems
Hydraulic power steering uses a belt-driven pump and fluid under pressure to assist steering. Common failure causes include a worn belt, a failing pump, or leaks in hoses and seals. When the pump stops delivering pressure, steering becomes heavy or nearly nonfunctional, particularly at low speeds. Leaks can also lead to fluid loss and additional damage if ignored.
Electric power steering systems
Electric power steering relies on sensors, a control module, and an electric motor to provide assist. Failures can stem from electrical faults, sensor issues, or motor problems. In some vehicles, the system may enter a limited or “fail-safe” mode with reduced or no assist. Warning lights on the dash typically alert you to an issue.
Should you drive with a broken power steering?
Generally, driving with a broken power steering is not recommended. Loss of assist makes steering heavier and less predictable, which can slow your reaction time and complicate lane changes, turns, and parking. The risk is higher in traffic, at highway speeds, or in poor weather. If you notice a steering problem, it's safer to stop at a safe location and arrange for repair or towing rather than continuing to drive.
Immediate steps if it fails while driving
If power steering fails while you’re behind the wheel, follow these steps to reduce risk and reach a safe stopping point.
- Gently ease off the accelerator and slow down by braking smoothly while signaling to pull over.
- Steer with both hands and keep your movements deliberate and gradual to avoid overcorrecting.
- Turn on hazard lights to alert other drivers as you move to the side of the road or a safe area.
- If any warning lights appear or you hear unusual noises, do not attempt to diagnose or repair the system while driving.
- Once stopped, check for obvious issues like fluid leaks (in hydraulic systems) or visible damage to the belt or electrical components, and call for roadside assistance if you are unsure.
Upon reaching a safe location, call roadside assistance or a tow service. Driving with a known power steering fault significantly increases safety risks, and a professional repair is typically required to restore proper steering feel and handling.
What to inspect or have checked after you stop
After pulling over, there are common causes a mechanic will inspect to determine the fault and the necessary repair.
- Power steering fluid level and condition (hydraulic systems): check for leaks and refill only as specified by the manufacturer.
- Drive belt condition and tension (for hydraulic systems): a worn or broken belt can stop assist.
- Warning lights or messages related to the steering system or vehicle’s computer modules.
- Electrical connections, sensors, and motor function (for electric power steering): faults here can disable assist.
- Overall steering rack or pump integrity and potential component failures requiring professional replacement.
Most power steering faults require professional diagnosis and repair. Attempting to operate the vehicle until the issue is resolved can cause further damage and compromise safety.
When to tow vs repair
Towing is often the safest option when the power steering system is unreliable or completely failed, especially if you cannot safely reach a repair facility. Some issues may be inexpensive to fix, such as topping up fluid or replacing a belt, but many require professional service, alignment checks, or a replacement part. Contact a dealership or trusted auto shop for guidance based on your vehicle’s make and model.
Summary
Power steering loss creates heavy, less controllable steering and increases crash risk. Do not press on with driving if the system is broken; pull over safely and seek professional help or have the vehicle towed. Regular maintenance—checking fluid levels, belts, and steering components—can prevent many failures, and understanding your vehicle’s power steering type helps you recognize issues early.
