Can You Drive With Power Steering Failure?
Yes, most cars can still steer without power assist, but only enough to safely pull over or drive a very short distance at low speed to a repair shop; continuing to drive is risky, requires much greater steering effort—especially when turning or parking—and can damage components, particularly in vehicles with hydraulic systems or a failed serpentine belt. Understanding the type of power steering your car uses and the symptoms you’re seeing will help you decide whether to stop immediately or cautiously proceed to a safe location.

What Happens When Power Steering Fails
Modern vehicles use either hydraulic power steering (HPS), electric power steering (EPS), or electro-hydraulic systems. When assist fails, the mechanical link to the wheels remains, so you retain steering control, but the wheel becomes significantly heavier. At higher speeds, you may barely notice; at low speeds, parking-lot maneuvers can feel nearly impossible. Warning indicators often include a steering wheel icon (amber or red) and messages such as “Power Steering Assist Fault” or “Service Power Steering.”
Hydraulic Power Steering (HPS) Failure
HPS relies on a belt-driven pump and fluid to provide assist. A leak, low fluid, or pump failure can suddenly remove assist and may cause whining noises or a burning fluid smell. If the serpentine belt breaks or slips, you can also lose the alternator and, in many vehicles, the water pump—raising the risk of battery discharge and rapid engine overheating. Driving with a major fluid leak can destroy the pump and, in rare cases, pose a fire hazard if fluid contacts hot surfaces.
Electric Power Steering (EPS) Failure
EPS uses an electric motor and control module. When it faults, you’ll lose assist but retain mechanical steering. Causes range from low system voltage (weak battery or failing alternator) to sensor faults (torque/steering angle), blown fuses, or a failed EPS motor/module. Assistance can drop out intermittently, which is unpredictable and unsafe. Some vehicles briefly restore assist after a restart, but recurring faults need diagnosis rather than repeated resets.
Is It Safe (and Legal) to Keep Driving?
It’s generally unsafe to continue driving far without power assist, particularly at low speeds, in heavy traffic, or on winding roads. While not explicitly illegal in most places, operating a vehicle in an unsafe condition can draw citations and liability if an incident occurs. If steering effort is extreme or assist cuts in and out unpredictably, stop and seek a tow. If your vehicle uses a serpentine belt for multiple accessories and that belt has failed, do not continue—overheating or electrical failure can follow within minutes.
What To Do Immediately If Power Steering Fails While Driving
The following steps can help you stay in control and minimize risk if assist suddenly drops out while you’re moving.
- Grip the wheel firmly with both hands and keep the vehicle steady in your lane.
- Switch on hazard lights to alert other drivers if traffic conditions warrant.
- Avoid abrupt turns; gradually reduce speed using smooth braking.
- Use vehicle motion to your advantage—make any necessary turns while rolling slowly rather than from a stop.
- Signal and move to the right lane or shoulder as soon as it’s safe.
- Watch engine temperature and battery/charging warnings; pull over immediately if overheating or charging issues appear.
- Once stopped safely, turn off the engine, wait 30 seconds, and restart to see if an EPS fault clears—only if conditions are safe.
- Check for obvious issues: low fluid (HPS), a broken or missing belt, leaks under the car, or warning lights.
- If steering remains heavy or faults persist, arrange roadside assistance or towing rather than continuing.
- If you must drive, limit it to a very short, low-speed trip to a nearby shop on quiet roads.
These actions prioritize control and safety while helping you quickly decide whether a brief, careful drive to service is possible or whether a tow is the prudent choice.
Common Causes and Quick Checks
Several common issues can trigger the loss of power assist. These quick checks can help you triage the problem before deciding on next steps.
- Low or leaking power steering fluid (HPS): Look for a red/brown puddle, check the reservoir level and condition (foamy or dark fluid is a red flag).
- Failed or slipping serpentine belt (HPS and some accessories): Listen for squeal; visually inspect belt condition and tension; a missing belt is an immediate stop.
- Faulty power steering pump (HPS): Whining that rises with engine speed, heavy steering even when fluid is full.
- Rack-and-pinion issues: Stiff spots, clunks, or leaks around the rack boots.
- Blown fuse or relay (EPS/EHPS): Check the fuse box for steering-related fuses; replace only with the correct rating.
- Low battery voltage or failing alternator (EPS): Dim lights, battery warning lamp, or sluggish starts can precede EPS faults.
- Sensor or module faults (EPS): Intermittent assist, warning messages, or faults that briefly clear with a restart.
- Tire-related causes: Severely underinflated front tires can mimic steering failure by increasing steering effort.
While these checks can isolate obvious problems, accurate diagnosis often requires scan tools and pressure or electrical testing that a professional shop can provide.
Repairs and Costs
Costs vary by vehicle, system type, and parts availability. Here are typical ranges for common fixes; local labor rates and OEM vs. aftermarket parts can shift totals.
- Power steering fluid service/flush (HPS): $80–$150.
- Hose/line replacement (HPS): $150–$500 per hose, parts and labor.
- Power steering pump (HPS): $400–$1,000 installed.
- Rack-and-pinion replacement: $900–$2,500+ installed (often requires alignment).
- Serpentine belt and tensioner: $150–$450.
- EPS motor or control module: $600–$1,800+ depending on integration.
- Battery or alternator (EPS-related voltage issues): Battery $150–$300; alternator $400–$900 installed.
Obtain a written estimate and ask whether reprogramming, alignment, or calibration (e.g., steering angle sensor) is included, as these can affect the final bill and steering feel.
How To Prevent Power Steering Problems
Regular maintenance and a few habits can dramatically reduce the odds of sudden steering-assist loss.
- Check fluid level and condition (HPS) at each oil change; top off only with the specified fluid.
- Inspect the serpentine belt and tensioner annually; replace at the first signs of cracking or glazing.
- Keep front tires properly inflated and aligned to reduce steering load.
- Avoid holding the wheel at full lock for more than a few seconds (HPS), which overheats fluid and stresses the pump.
- Address battery/charging issues promptly; low voltage is a common EPS trigger.
- Scan for codes if steering warnings appear, even intermittently; early fixes prevent bigger failures.
These preventive steps keep assist systems healthy and provide early warning of issues before they become safety hazards.
When It’s Okay to Drive, and When to Park It
Reasonable to drive briefly
Steering is consistently heavy but predictable; no overheating or charging warnings; no major leaks; a short, low-speed route to a shop is available.
Park it and call for a tow
Intermittent or unpredictable assist, a broken/missing belt, rapid fluid loss, engine overheating, battery/charging warnings, or steering so heavy you can’t safely maneuver.
Summary
You can usually steer a vehicle without power assist, but it’s physically demanding and risky—appropriate only for pulling over or a very short, careful drive to service. If a serpentine belt has failed, fluid is pouring out, assist is intermittent, or other critical warnings appear, stop and arrange a tow. Quick checks—fluid, belt, fuses, voltage, tire pressure—can guide your next step, and timely maintenance greatly reduces the chance of sudden failure.
What to do if power steering goes out while driving?
If power steering fails while driving, don’t panic, turn on your hazard lights, and gradually slow down to a safe stop on the side of the road. Grip the steering wheel firmly with both hands to maintain control, as the wheel will require much more effort to turn. Once stopped, turn off the engine and call for a towing service to take your vehicle to a mechanic to prevent further damage, especially if power steering fluid is leaking.
While Driving
- 1. Stay Calm and Maintain Control: The vehicle is still steerable, but it will require significant physical effort to turn the wheel.
- 2. Signal for Help: Turn on your hazard lights to alert other drivers that you are experiencing a problem and need to pull over safely.
- 3. Slow Down Gradually: Ease off the accelerator and use your brakes carefully to reduce speed.
- 4. Maneuver to Safety: Slowly and smoothly maneuver your vehicle to the side of the road or a safe location.

- Potential for Complete Failure: Driving with a failing system could lead to total steering loss, which would be dangerous.
Can you still drive if power steering fails?
Yes, you can typically drive a vehicle if the power steering goes out, but it will require significantly more physical effort to steer, especially at low speeds or when parking. Driving without power steering is generally safe for short distances to a mechanic if you are careful, but it can be dangerous if you can’t steer quickly enough in an emergency. You should drive cautiously, using both hands on the wheel, and get the system repaired as soon as possible to avoid further damage to the power steering pump and other components.
What happens when power steering fails?
- Heavier Steering: The system provides hydraulic assistance, so without it, turning the wheel becomes much harder.
- Increased Difficulty at Low Speeds: You’ll find it especially challenging to turn the wheel when the car is stopped or moving slowly.
- Potential for Damage: Driving without fluid can cause the pump to overheat and fail, and the belt that powers the pump can snap.
- Danger in Emergencies: It can be difficult to react quickly enough during an emergency, making it more likely to cause an accident.
What to do if your power steering fails:
- Park Safely: Pull over to a safe location on the side of the road as soon as possible.
- Assess the Steering: Turn the wheel to see how much effort it takes.
- Check Fluid (if applicable): For hydraulic systems, check if the power steering fluid is low and add the correct type if needed.
- Drive Cautiously: If it’s manageable, drive slowly and carefully to the nearest mechanic.
- Use Both Hands: Grip the steering wheel firmly with both hands to maintain control.
- Avoid Sharp Turns: Be prepared for the increased effort needed for sharp or sudden turns.
- Call a Tow Truck: If you feel you cannot accurately steer the vehicle, it’s safer to call for a tow truck.
Get it fixed:
- Repair ASAP: Get your vehicle to a qualified mechanic as soon as possible to prevent further damage to the system.
- Consult a Professional: A mechanic can diagnose the issue and provide an accurate estimate for repairs.
Is it expensive to fix power steering?
Yes, fixing a power steering issue can be expensive, with costs ranging from under $100 for a simple fluid flush to $800 or more for a new power steering pump, and even higher for complex repairs like a steering rack replacement.
