This procedure addresses the power steering reservoir replacement on a 2016-2024 Hyundai Tucson 2.5L I4 AWD, which uses electric power steering and does not have a traditional hydraulic reservoir.

Warnings

Tools required

Preparation

1. Verify your vehicle actually has electric power steering by checking under the hood for the absence of a power steering fluid reservoir
2. If you have a power steering fluid reservoir, your vehicle may have a different engine configuration than specified
3. Consult your owner's manual or the engine bay label to confirm your exact powertrain configuration

Procedure

1. 1

   Verify Electric Power Steering System
   Open the hood and inspect the engine bay. The 2.5L I4 engine in the 2016-2024 Tucson uses an electric power steering motor mounted on the steering column or rack assembly, not a hydraulic pump with reservoir. Confirm there is no power steering fluid reservoir on the driver's side of the engine bay where it would traditionally be located on hydraulic systems.
2. 2

   Locate Electric Power Steering Components
   The electric power steering motor is integrated with the steering rack assembly under the vehicle. If experiencing steering issues, inspect the EPS motor connector for damage, corrosion, or loose connections. Check for diagnostic trouble codes using an OBD-II scanner, as EPS faults will trigger warning lights and store codes.
3. 3

   Inspect Steering System for Issues
   If you were attempting to service the power steering system due to noise, stiffness, or warning lights, these symptoms on an EPS system indicate electrical or motor issues rather than fluid-related problems. Common EPS issues include faulty torque sensors, motor failure, or wiring problems that require electrical diagnosis rather than fluid service.

Reassembly

1. No reassembly required as this vehicle does not have a serviceable power steering reservoir
2. If steering issues persist, consult a qualified technician for electric power steering system diagnosis

Verification

• Confirm your vehicle has electric power steering by the absence of any power steering fluid reservoir and pump
• Verify no power steering fluid leaks exist (because there is no fluid in the system)
• If warning lights are present, retrieve diagnostic codes to identify the actual EPS component requiring service
