The answer depends on which steering system your ES 350 uses. Most newer ES 350 models rely on electric power steering (EPS) and do not have a hydraulic power steering pump to replace. If you own an older ES 350 with hydraulic power steering, a pump replacement typically runs roughly $600 to $900 in total, depending on parts and labor. In cases where EPS components fail, costs can range higher, often between $800 and $2,000 or more if the steering rack or EPAS module must be replaced.
System overview and what changes across model years
The Lexus ES 350 has evolved from a hydraulic power steering system in earlier years to an electric power steering (EPS) setup in many later models. That means the “pump” you might be asked to replace today is not always present. Understanding which system your car uses is essential before budgeting for repairs.
Hydraulic power steering in older ES 350 models
In the era when the ES 350 used a belt-driven hydraulic pump, the cost to replace the pump breaks down into parts, labor, and any ancillary components. Here is a typical breakdown:
- Parts for the pump itself: roughly $100–$350, depending on OEM vs. aftermarket options.
- Labor to remove the old pump and install a new one: about 1–3 hours, typically $100–$450 depending on shop rates.
- Additional items that are commonly replaced during a pump job (belt, tensioner, hoses, reservoir): $50–$150.
Overall, most owners see a total in the ballpark of $300–$900, though prices can vary by region, shop, and parts chosen. Always check whether diagnostic work is required to confirm the failure is the pump itself rather than a related belt or fluid issue.
Electric power steering (EPS) era
In most ES 350 models from about 2013 onward, the vehicle uses electric power steering, which eliminates the hydraulic pump entirely. When EPS components fail, the costs reflect the parts and labor for the electric system rather than a pump replacement:
- EPS motor or control unit replacement: roughly $600–$1,200 for parts, plus $200–$500 for labor.
- Total typical range for EPS motor replacement: about $800–$1,700.
- More extensive failures (EPAS module, steering rack, or related electronics) can push total costs higher, generally in the $1,500–$3,500 range depending on parts and labor.
Because EPS relies on an electric motor and control electronics, many repairs involve the motor, sensors, or the steering rack rather than a single replaceable pump. Always confirm whether your ES 350 actually has hydraulic PS or EPS before budgeting for repairs.
What factors influence the final price
Several variables determine the bottom-line cost for any power steering repair on a Lexus ES 350. The following factors regularly affect quotes you’ll receive from shops or the dealer:
- The exact model year and whether the car uses hydraulic PS or EPS.
- Regional labor rates and the shop’s pricing policy (dealer vs. independent shop).
- Parts choice (OEM vs. aftermarket) and the availability of remanufactured components.
- Diagnostic fees to confirm the fault and identify the correct repair path.
- Whether additional components (belts, pulleys, hoses, reservoirs) are replaced in the same service.
- Warranty coverage or pricing differentials for vehicles still under a powertrain or extended warranty.
These factors mean even within the same system type, quotes can vary substantially. Always request a written estimate that itemizes parts and labor, and ask about diagnostics if you’re unsure what’s failing.
How to plan for replacement or repair
If you’re preparing for a potential power steering repair, use these steps to get informed quotes and avoid surprises.
- Confirm your ES 350’s steering system type (hydraulic vs. electric) using the VIN or a dealer/repair manual.
- Obtain multiple quotes (at least three) from both the dealer and independent shops to compare parts and labor.
- Ask whether the quote includes diagnostic charges, and whether the price covers OEM or aftermarket parts.
- Get a written breakdown of parts, labor hours, and hourly rate; request estimated timelines for completion.
- Clarify what happens if the problem is not the pump (for hydraulic systems) or if EPS components fail (motor, module, or rack).
- Inquire about warranties on parts and labor and any available discounts or financing options.
- Consider a pre-purchase or extended maintenance plan that might cover future EPS-related repairs if applicable.
Planning ahead can help you navigate the range of possible costs and choose the option that best fits your car’s system and your budget.
Summary
For the Lexus ES 350, the cost to replace a power steering pump depends on the steering technology in your car. Older ES 350s with hydraulic PS typically run about $300–$900 in total, including parts and labor. Newer ES 350 models with electric power steering do not have a pump to replace; repairs focus on the EPS motor, sensors, or steering rack, with typical costs ranging from $800 to $1,700, and potentially higher for more extensive component failures. Always verify the system type and obtain multiple detailed quotes to avoid surprises.
Can I still drive with a bad power steering pump?
It's not safe to drive with a bad power steering pump, as it can make steering difficult and unpredictable, especially at lower speeds.

How long does it take to replace a power steering pump? Depending on your vehicle's complexity, it could take as little as an hour or more than three hours.
How much does it cost to replace the power steering pump on a Lexus ES350?
The average cost for a Lexus ES350 Power Steering Pump Replacement is between $634 and $725.
What is the common problem in Lexus ES 350?
Oil Leaks. The Lexus ES 350 also has some reports of excessive or sudden oil leaks, especially in the earlier models. More recent models don't seem to have as many problems, but unfortunately, oil leaks and oil consumption are only some of the issues with the ES 350's engine.
