2020 Subaru Legacy: No Power-Steering Pump Fitted

The 2020 Subaru Legacy does not use a traditional hydraulic power-steering pump. Technical documentation for the seventh‑generation Legacy on the Subaru Global Platform specifies an Electric Power Steering (EPS) system—also called Motor‑Driven Power Steering (MDPS)—with an electric assist motor integrated at the steering rack. Subaru’s service information (STIS Steering section) details an electric rack with no hydraulic circuit, and the 2020 Legacy Owner’s Manual describes an EPS system with an EPS warning light rather than any reference to power‑steering fluid. Subaru’s new‑model technical training for the 2020 Legacy/Outback further notes the adoption of EPS for efficiency and advanced driver‑assist integration. In short, there’s no belt‑driven pump, no fluid reservoir, and no hydraulic hoses on this model year.

Why skip the pump? An electric system brings a few key wins:

• Better fuel efficiency and reduced parasitic drag, since there’s no engine‑driven pump.
• Cleaner packaging and fewer leak points—no fluid lines, seals or reservoirs to maintain.
• Smoother integration with driver‑assist features (like lane‑centering), as the control unit can vary steering assist electronically.

What does this mean for servicing? There’s no power‑steering fluid to check or change on the 2020 Legacy. Instead, workshops focus on EPS health checks. That includes scanning for steering control unit fault codes if the EPS warning light appears, confirming battery and charging system health (low voltage can upset EPS), and inspecting the steering rack boots, tie‑rod ends and front suspension for wear. Wheel alignment, correct tyre pressures and even tread wear are also important to keep steering feel consistent on Aussie and Kiwi roads.

If the steering ever feels unusually heavy at low speeds, intermittent, or if the EPS light comes on, it’s worth booking a diagnostic. A technician can verify live data from the EPS control unit, check the steering torque sensor calibration, and ensure there aren’t any wiring or connector issues. But for everyday owners, it’s simple: no pump, no fluid, fewer hassles—just keep the tyres, alignment and battery in good nick and the Legacy’s electric steering will do its thing for many kilometres.

• Does the 2020 Subaru Legacy have a power‑steering pump?
  No. It uses Electric Power Steering (EPS), so there’s no hydraulic pump, fluid reservoir or hoses.
• Is there any power‑steering fluid to change on a 2020 Legacy?
  No. EPS doesn’t use hydraulic fluid. Routine checks focus on battery health, wheel alignment and suspension/steering components.
• What should be done if the EPS warning light comes on?
  Have it scanned for fault codes, verify charging system voltage, and inspect wiring/connectors at the rack. A qualified workshop can recalibrate or repair as needed.
