Parts for your 2020 Nissan Serena-Power steering fluid

2020 Nissan Serena Power Steering Fluid — Is It Needed?

Power‑steering fluid isn’t relevant to the 2020 Nissan Serena. Technical documentation for the C27‑series Serena (covering 2016–on, including MY2020) specifies an Electric Power Steering (EPS) system rather than a hydraulic setup. The Nissan Serena C27 Service Manual, Steering (ST) section, details an EPS configuration comprising an electric assist motor, torque sensor and EPS control unit integrated with the steering gear, with no hydraulic pump, hoses or reservoir listed. The 2020 Serena Owner’s Manual also references an EPS warning light and contains no power‑steering fluid specification or service interval. Nissan’s parts catalogues for the C27 further show no power‑steering pump or fluid reservoir assembly for this model.

Because the Serena uses EPS, there’s simply no hydraulic fluid to top up or replace. Assist is provided by an electric motor on the steering rack, drawing power from the 12‑volt system and managed by the EPS control unit. This design reduces parasitic drag on the engine, improves fuel efficiency, and slashes fluid‑related maintenance. It also helps deliver consistent steering assist and integrates neatly with driver‑assist tech like ProPILOT.

Owners sometimes look for a “missing” reservoir under the bonnet—there isn’t one for power steering on this model. Any fluid containers seen will be for items like brake fluid or engine coolant, adding power‑steering or ATF fluid anywhere on a 2020 Serena is not appropriate.

While there’s no power‑steering fluid service, a smart approach to steering system care on the Serena includes:

• 12V battery health checks (EPS is sensitive to low voltage).
• Wheel alignment and tyre condition/pressures to protect the steering gear and ensure light, even steering feel.
• Inspection of suspension/steering joints and rack boots at regular servicing intervals.
• Diagnostic scans and software updates if the EPS warning lamp appears or the steering feels heavy/intermittent.

If heavy steering, warning lights, or unusual noises occur, a technician should test the 12V charging system, check for EPS fault codes, and inspect mechanical linkages. No fluid change will resolve EPS faults on this vehicle, because fluid isn’t part of the system.

FAQs

Does a 2020 Nissan Serena need power‑steering fluid?
No. The 2020 Serena uses Electric Power Steering (EPS) with an electric assist motor and control unit. There’s no hydraulic pump or reservoir, so there’s no power‑steering fluid to check or replace.

There’s a whine or heavy feel while turning—could it be low power‑steering fluid?
Not on this model. A whine or heavy steering is more likely related to low 12V battery voltage, tyre or alignment issues, or an EPS fault. A workshop can scan the EPS system and check battery/charging health.

How is steering serviced on a 2020 Serena without fluid?
Routine care focuses on the 12V battery and charging system, tyre pressures and alignment, plus inspection of steering and suspension joints. If the EPS light comes on, technicians perform diagnostics and software checks rather than any fluid maintenance.
