Parts for your 2017 Nissan Serena-Power steering fluid

2017 Nissan Serena power-steering fluid: not applicable (it runs Electric Power Steering)

For the 2017 Nissan Serena (C27), power-steering fluid isn’t a thing. This model uses an Electric Power Steering (EPS) system, so there’s no hydraulic pump, no hoses and definitely no reservoir to top up. This isn’t guesswork — the Nissan Serena C27 Service Manual (Steering Control System/EPS section) describes a motor-driven steering rack with electronic control rather than a hydraulic circuit. The owner’s manual maintenance schedule for the C27 also contains no power-steering fluid checks. Nissan’s launch material for the C27 generation likewise notes the move to electric power steering, highlighting efficiency benefits common to EPS systems.

Because the Serena’s steering assist is delivered by an electric motor on the rack and an EPS control unit, there’s simply no hydraulic fluid to replace, flush or monitor. That’s by design: EPS trims parasitic losses (no belt-driven pump), improves fuel economy and reduces maintenance. It also allows more precise, software-based tuning of steering feel and integrates neatly with driver-assist systems.

What does that mean for servicing? Focus on the bits that actually matter for EPS:

• Keep the 12V battery healthy — weak voltage can make the steering feel heavy, especially at low speeds or on cold starts.
• Check wheel alignment and tyre condition, EPS can only do so much if geometry or tyres are off.
• Inspect rack boots, column joints and front-end bushes for wear that can introduce play or noise.
• Have workshops scan for EPS fault codes and apply any control unit updates when the vehicle is serviced.
• Confirm EPS power and ground connections are clean and secure after any collision or water ingress.

If the steering effort suddenly changes, a battery test and a quick diagnostic scan are smart first steps. But as for “power-steering fluid” on a 2017 Serena — there isn’t any to buy, check or replace.

FAQs

Does a 2017 Nissan Serena use power-steering fluid?
No. The C27 Serena runs Electric Power Steering (EPS), which uses an electric motor and control unit instead of a hydraulic pump and fluid. There’s no reservoir to check and no fluid to replace.

Why might the steering feel heavy on a 2017 Serena if there’s no fluid?
EPS relies on a healthy 12V electrical system. A weak battery, poor charging, corroded terminals or EPS fault codes can make assistance feel reduced. A quick battery test and scan usually points you in the right direction.

What steering maintenance should be done during servicing?
Have the 12V battery and charging system checked, inspect rack boots and column joints, keep tyres and alignment spot-on, and ask for an EPS diagnostic scan. Workshops can also apply any available EPS software updates.
