Parts for your 2017 Subaru Outback-Power steering fluid

2017 Subaru Outback power-steering-fluid

For the 2017 Subaru Outback, power-steering fluid isn’t relevant because that model uses Electric Power Steering (EPS), not a hydraulic system. EPS uses an electric motor and a control module to assist steering, so there’s no hydraulic pump, no hoses, and no reservoir to top up. This is confirmed in technical material such as the 2017 Subaru Outback Owner’s Manual (Steering – Electric Power Steering), the Subaru Factory Service Manual for the BS-series Outback (Chassis/EPS section), and Subaru Australia’s maintenance schedule for MY17, which lists no power-steering-fluid service item.

Why did Subaru go electric? EPS reduces weight and parasitic drag on the engine, helping fuel economy and lowering emissions. It also offers smarter, variable assistance tuned by the control unit, and removes a notable failure point—leaks—from the equation. Because there’s no hydraulic circuit, owners won’t find a power-steering-fluid reservoir under the bonnet on a 2017 Outback, and there’s no fluid to inspect, top up, or flush during servicing.

Even without fluid, steering care still matters. A technician will typically check for any EPS warning lights, scan for steering-related fault codes, and inspect the battery and charging system—since EPS relies on healthy electrical supply. Steering feel concerns are more likely to be caused by tyre pressures, alignment, worn suspension components, or wheel/tyre damage rather than anything to do with fluid.

• If steering feels heavy at parking speeds, first check tyre pressures and the 12V battery’s state of health.
• If an EPS warning appears on the dash, have the system scanned—faults can relate to the torque sensor, steering angle sensor, or voltage supply.
• Regular alignments and suspension checks help keep steering accurate and light.

Technical sources referenced:

• 2017 Subaru Outback Owner’s Manual – Steering: Electric Power Steering description (no fluid service item).
• Subaru Factory Service Manual (BS-series Outback, 2015–2019) – Chassis/EPS section detailing electric motor assist and control unit (no hydraulic pump/reservoir).
• Subaru Australia Maintenance Schedule (MY17 Outback) – no listed power-steering-fluid replacement.

Popular questions

Does a 2017 Subaru Outback need power-steering fluid?
No. The 2017 Outback uses Electric Power Steering, so there’s no hydraulic fluid involved. There’s nothing to top up or flush as part of routine service.

Where is the power-steering fluid reservoir on a 2017 Outback?
There isn’t one. Because the car uses an electric motor for steering assist, you won’t find a pump, hoses, or a reservoir under the bonnet.

What steering maintenance should be done on a 2017 Outback?
Focus on tyre pressures, wheel alignment, suspension and steering joint inspections, and battery/charging system health. If an EPS light appears, have the system scanned to pinpoint any sensor or voltage-related issues.
