Parts for your 2017 Subaru Impreza-Power steering fluid

2017 Subaru Impreza power steering fluid — what owners need to know

Chasing power steering fluid for a 2017 Subaru Impreza (GK/GT)? There isn’t any to top up. This model uses an electric power steering (EPS) rack, so it has no hydraulic pump, no hoses and no power steering fluid reservoir.

This isn’t guesswork. The 2017 Subaru Impreza Owner’s Manual describes the car as having electric power steering, including an EPS warning light and no checks or service items for power steering fluid. Subaru’s factory Service Manual (via the Subaru Technical Information System, “STIS”) labels the system “Electric Power Steering (EPS)” and details components like the steering gearbox with an integrated assist motor, torque sensor and EPS control unit — but no hydraulic pump or lines. The published maintenance schedule for 2017 Impreza lists engine oil, coolant, brake and transmission fluids, yet omits power steering fluid entirely, because it’s not used.

Why Subaru doesn’t use fluid here is straightforward: the EPS motor provides assist directly on the steering rack. That means better fuel efficiency (no belt-driven pump dragging on the engine), fewer leak points, and consistent, tuneable steering feel. It also trims down routine servicing — there’s simply no power steering fluid to check, flush or replace.

If someone’s hunting for a power steering fluid change on a 2017 Impreza, it’s not a thing. Instead, attention during servicing is better spent on items that actually influence steering feel and safety in Aussie and Kiwi conditions:

• Battery health: EPS relies on stable 12V supply. A weak battery or dodgy terminals can make the steering feel heavy or trigger the EPS light.
• Tyre pressures and wheel alignment: Low pressures or poor alignment can mimic heavy steering and increase tyre wear.
• Front-end inspection: Check tie-rod ends, rack boots and suspension bushes for wear that can affect steering response.
• Diagnostics if warning lights show: If the EPS light appears, a scan with a Subaru-capable tool (e.g., Subaru Select Monitor) can pinpoint sensor or module faults.

Bottom line: for the 2017 Impreza, power steering fluid isn’t relevant because the car doesn’t use it. Keep the electrics healthy, the tyres sorted and the alignment on spec, and the steering will feel just right.

FAQs

Where do you top up power steering fluid on a 2017 Subaru Impreza?
There’s nowhere to top up because the 2017 Impreza uses electric power steering and has no hydraulic reservoir. If the steering feels heavy, look to tyre pressures, battery condition or an EPS warning light rather than fluid levels.

How often should the power steering fluid be changed on a 2017 Subaru Impreza?
It doesn’t require a change — there’s no fluid. Follow the normal service schedule and keep the electrical system and front-end components in good nick to maintain steering performance.

The steering feels heavy — do I need to add fluid?
No. For this model, heavy steering is more likely low tyre pressures, a weak 12V battery, or an EPS system issue. If the EPS light is on, have it scanned with a Subaru-capable diagnostic tool to check the torque sensor, motor or control unit.
