How much does it cost to fix a power steering fault?

Expect to pay roughly $150–$900 for common fixes and anywhere from $1,200–$3,500+ for major components, depending on whether your car uses a hydraulic system or electric power steering (EPS). Minor issues like a fluid flush or hose replace are on the low end, while pumps, racks, or EPS assemblies push costs higher. Prices vary by vehicle, parts availability, and labor rates.

Typical repair costs by fault

Power steering systems come in three broad types—hydraulic, electro‑hydraulic, and fully electric (EPS)—and each has its own failure patterns and price ranges. The figures below are typical installed prices in the U.S., including parts and labor; luxury brands, trucks, and newer EPS systems often cost more.

Hydraulic power steering repairs (most vehicles 1990s–2010s)

Hydraulic systems rely on fluid, hoses, a belt-driven pump, and a steering rack. Leaks and worn pumps are common. These are the typical costs you might encounter.

• Inspection/diagnostic fee: $50–$150 (often applied to the repair)
• Fluid top-off and leak dye test: $25–$60 (diagnostic only; not a fix)
• Fluid flush with correct spec fluid: $70–$150
• Return hose replacement: $100–$250
• High-pressure hose replacement: $150–$400
• Reservoir (with built-in filter, if applicable): $100–$250
• Drive/serpentine belt replacement (if slipping/squealing): $100–$250
• Power steering pump replacement: $300–$900 (premium/luxury: $800–$1,500)
• Rack-and-pinion replacement (reman or new): $1,200–$2,800 (economy cars can be $800–$1,400)
• Wheel alignment after rack replacement: $80–$150 (additional)

Most hydraulic leaks start small, but neglect can lead to pump failure and rack damage. If a rack is leaking at the seals, replacement is the common fix; rebuilds are less common at retail shops.

Electric power steering (EPS) and electro‑hydraulic repairs (many 2010s–present)

EPS uses electric motors and sensors rather than fluid. Failures can involve sensors, motors, control modules, or the entire steering rack assembly. Electro‑hydraulic systems use an electric pump but still have fluid and hoses.

• Software update/recalibration: $120–$250
• Torque/angle sensor replacement: $400–$1,100
• Steering column assembly (with integrated sensor): $700–$1,800
• EPS assist motor replacement: $400–$1,200
• EPS control module (if separate) with coding: $300–$900
• Complete EPS rack assembly: $1,500–$3,500+ (some luxury/trucks: up to $4,000)
• Electro‑hydraulic pump module: $600–$1,500

Because EPS components often require programming and calibration, labor and dealer-level tooling can add to the bill. In many modern cars, the motor and module are integrated into the rack, pushing costs higher.

What drives the price?

Several variables determine your final repair total. Understanding them helps explain why quotes can vary widely between shops and vehicles.

• System type: Hydraulic fixes are often cheaper than EPS rack replacements.
• Vehicle make/model: Luxury brands and trucks typically have higher parts and labor costs.
• Part choice: OEM vs. aftermarket vs. remanufactured components change price and warranty.
• Labor time: Rack jobs can take 3–7 hours; hoses 0.5–1.5 hours; pumps 1–3 hours.
• Labor rate: Commonly $90–$200 per hour in the U.S., higher in some metro areas.
• Programming/alignment: EPS coding and post-repair wheel alignment add cost.
• Related damage: Driving with low fluid can kill the pump and contaminate the rack.

When comparing estimates, ask for a parts/labor breakdown and whether programming, fluids, shop supplies, and alignment are included to avoid surprises.

Diagnostics and time estimates

Most shops start with a diagnostic fee ($50–$150) that’s typically credited if you proceed with repairs. Time-on-task varies by repair type and vehicle packaging.

• Hose or reservoir replacement: 0.5–1.5 hours
• Pump replacement: 1–3 hours
• Rack-and-pinion or EPS rack replacement: 3–7 hours, plus alignment and potential programming
• EPS sensor/module work: 1–3 hours, plus calibration

Complex packaging, corrosion, or seized fasteners can extend labor. EPS jobs may require specialized scan tools for calibration.

Can you keep driving with a power steering fault?

Steering may still work without assist, but it can become very heavy, especially at low speeds, and can be unsafe. Leaks can worsen quickly, and running a hydraulic pump dry can cause expensive collateral damage.

• Do not continue driving if the steering becomes suddenly heavy, jerky, or binds.
• For hydraulic systems, check fluid level; low fluid indicates a leak that needs repair.
• For EPS warning lights, intermittent assist loss warrants prompt diagnosis to avoid loss of control.
• Whining, groaning, or burning-smell symptoms should be addressed immediately.

If you must move the car, keep speeds low and avoid tight maneuvers; arrange for towing when steering effort is excessive or assist is intermittent.

Ways to save and get an accurate quote

You can often reduce costs with smart part choices and by getting multiple estimates. Here’s how to approach it.

• Get two to three written quotes with parts/labor breakdowns.
• Ask if a remanufactured rack/pump with a strong warranty is available.
• Confirm whether programming, alignment, fluids, fees, and taxes are included.
• Check for recalls or technical service bulletins (TSBs) for EPS faults on your model.
• Use OEM fluid and follow bleed/calibration procedures to prevent repeat failures.
• Consider dealership service for EPS programming if your independent shop lacks tools.

A clear, apples-to-apples estimate helps you avoid add-ons and ensures the repair solves the root cause, not just the symptom.

Summary

Fixing a power steering fault can cost as little as $70–$150 for a fluid service or several thousand dollars for an EPS rack. Most common repairs land between $150 and $900, while pumps and racks—especially on newer EPS-equipped or luxury vehicles—drive costs to $1,200–$3,500+. A proper diagnosis, transparent quotes, and the right parts choice are the keys to controlling the bill and restoring safe, predictable steering.

How do you fix a power steering fault?

Unscrew the cap of the power steering pump and check the fluid level. If it’s not full, buy power steering fluid from your local automotive supply store and refill the pump. If you have to add power steering fluid frequently, you may have a leak in your car’s steering system.

Are power steering issues expensive to fix?

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. The final cost depends on the specific problem, your vehicle’s make and model, the parts used (OEM vs. aftermarket), and your location. 
Breakdown of Common Repairs and Costs

• Power Steering Fluid Flush: Opens in new tabIf the issue is dirty fluid, this can resolve the problem for approximately $50 to $150. 
• Power Steering Pump Replacement: Opens in new tabThis is one of the more expensive repairs, with average costs ranging from $500 to $900, though it can go higher for luxury or large vehicles. 
• Power Steering Hose Replacement: Opens in new tabA leaking hose is generally a less expensive repair, potentially costing around $60 to $150, depending on the specific hose and labor involved. 
• Steering Rack Replacement: Opens in new tabThis is a significant and expensive repair, with parts and labor for a steering rack replacement costing several hundred dollars. 

Factors Affecting Cost

• Vehicle Make and Model: Luxury cars and larger vehicles typically have more expensive parts and labor. 
• Part Type: Using an Original Equipment Manufacturer (OEM) part from your car’s manufacturer is usually more expensive than an aftermarket part. 
• Labor Costs: The hourly rate for mechanics varies by location and shop. 
• DIY vs. Professional Repair: If you are comfortable with car maintenance, you can save money by doing some repairs yourself, but it’s important to ensure you have the right tools and knowledge. 
• Additional Repairs: Power steering issues can sometimes lead to other necessary repairs, such as a wheel alignment after a steering rack replacement. 

Can I drive my car with a power steering fault?

If your power steering warning light is on, it indicates there is an issue with the system – and should be checked as soon as possible. You should not drive the vehicle until the issue has been investigated and fixed. If your power steering warning light is on, the best course of action is to contact a mobile mechanic.

How much does it cost to fix the power steering assist fault?

The expense of fixing your electric power steering system by a certified mechanic depends on which parts need replacement. The total repair costs typically range between $100 and $1050.
