Parts for your 2012 Subaru Impreza-Power steering fluid

2012 Subaru Impreza power steering fluid — is it used?

For the 2012 Subaru Impreza (GP/GJ), power steering fluid isn’t relevant because this model uses electric power steering (EPS), not a hydraulic system. This is confirmed in Subaru’s technical literature: the 2012 Subaru Impreza Owner’s Manual states the vehicle is equipped with electric power steering, and the Subaru Service Manual (Chassis/Steering, GP/GJ) details an EPS unit with no hydraulic pump, hoses or reservoir. Subaru’s product information for the 2012 model also highlights EPS as a fuel-saving update over earlier generations.

Because there’s no hydraulic pump or lines, there’s no power steering fluid to check, top up or replace. The EPS uses an electric motor and a control module to provide steering assist, which helps reduce parasitic drag on the engine, trims fuel use, and cuts down on maintenance. It also means no messy leaks and fewer components under the bonnet. For owners who might be used to older Subarus with a fluid reservoir on the passenger side of the engine bay, that reservoir simply isn’t there on the 2012 Impreza.

What should owners look after instead? While there’s no fluid service, it still pays to keep the steering system in good nick:

• Battery and charging health: EPS depends on stable voltage. A tired battery or weak alternator can affect steering assist.
• Tyre pressures and wheel alignment: Correct pressures and a proper alignment reduce steering load and keep the car tracking straight.
• Suspension and steering joints: Have tie-rod ends, ball joints and front struts inspected at service intervals for wear.
• Warning lights: If the EPS warning illuminates, have the fault codes scanned and addressed promptly.

Worth noting: performance variants like the WRX/STI of that era were on a different platform and typically used hydraulic power steering with fluid. But for the mainstream 2012 Impreza hatch and sedan (2.0i and similar trims), power steering fluid simply isn’t part of the servicing picture.

Popular questions about 2012 Subaru Impreza power steering fluid

Does a 2012 Subaru Impreza have power steering fluid?
No. The 2012 Impreza uses electric power steering, so there’s no hydraulic pump, no hoses and no reservoir to check. If someone is searching under the bonnet for a power steering cap, they won’t find one on this model. Subaru’s owner and service manuals for the 2012 GP/GJ series confirm EPS is fitted.

What maintenance replaces power steering fluid service on this model?
Focus on battery condition, charging output, tyre pressures, wheel alignment and regular inspections of steering and suspension joints. If an EPS warning light appears or the steering feels unusually heavy or inconsistent, a diagnostic scan will point to any sensor, wiring or module issues.

What if there’s a fluid leak near the steering?
On a 2012 Impreza with EPS, a leak around the front subframe or rack area is unlikely to be power steering fluid. It could be engine oil, transmission fluid, or even split CV-boot grease. If the vehicle is actually a WRX/STI from the same period (different platform), that system may be hydraulic—check the model badge and the handbook to confirm.
