Parts for your 2019 Nissan Serena-Power steering pump

Power Steering Pump on the 2019 Nissan Serena

The 2019 Nissan Serena is a popular multi-purpose vehicle known for its spacious interior and practical features, especially loved by families and those needing extra seating capacity. When it comes to its steering system, it is important to understand whether a traditional power steering pump is part of the setup.

For the 2019 Nissan Serena, particularly the models equipped with newer technology, a traditional hydraulic power steering pump is not fitted. Instead, this vehicle utilises an electric power steering system. This means there is no hydraulic fluid or pump involved, which is a shift from older models or other vehicles that rely on a power steering pump to assist with steering effort.

The reason behind the absence of a power steering pump in the 2019 Nissan Serena roots in advancements in automotive steering technology. Electric Power Steering (EPS) systems have become increasingly common because they offer several benefits:

• Improved fuel efficiency: Hydraulic pumps are driven by the engine belt, which consumes additional energy constantly, even when steering assistance isn't required. EPS only uses electrical power when assistance is needed, reducing parasitic engine losses.
• Reduced maintenance: Hydraulic systems require fluid changes, hoses, and pumps that can wear out and need replacing, whereas EPS systems mostly rely on electric motors and sensors, which are generally more reliable and maintenance-free over the vehicle's lifetime.
• Better integration with safety features: The electric system can integrate directly with driver assistance technologies, such as lane keep assist and automatic parking, allowing for enhanced control that hydraulic systems cannot easily provide.

So, rather than having a mechanical pump powered by the engine via a belt, the 2019 Nissan Serena's steering is assisted by an electric motor controlled by sensors that detect torque and steering angle. This setup makes the ride smoother and steering lighter at low speeds, while maintaining stability during high-speed cruising without the need for a traditional power steering pump.

For owners of a 2019 Nissan Serena, this actually means less hassle when it comes to steering maintenance. There is no hydraulic fluid to check or replace, no pump to wear out, no belts to adjust or replace, and no power steering hoses that may leak over time. The electric power steering system is designed to be largely maintenance-free, contributing to the vehicle's overall reliability and ease of ownership.

That said, while you don't have to worry about power steering pumps, there are still some key maintenance and checks to ensure your electric power steering system remains functional and responsive:

• Software updates: Since the EPS system is electronically controlled, Nissan may release updates to improve performance or fix bugs. Regular servicing at authorised workshops can include checks for the latest software versions.
• Steering system diagnostics: If the steering feels unusually heavy or you notice warning lights on your dashboard, it's important to get the system scanned with the proper diagnostic tools. Electric motors, sensors, or wiring can occasionally develop faults that will require professional attention.
• Tire and suspension checks: Steering effort and feel can also be affected by under-inflated tyres or worn suspension components. Regular tyre pressure checks, wheel alignments, and suspension inspections play a part in maintaining smooth steering operation.

Should any issue arise with your 2019 Nissan Serena's electric power steering system, it is best left to trained technicians who understand the electronics and mechanics involved. Unlike hydraulic systems where you might replace a power steering pump, EPS repair will usually involve diagnostics, sensor replacement, or sometimes the electric motor unit itself. Always consult Nissan authorised service centres for accurate diagnosis and repairs.

Overall, the shift to electric power steering in the 2019 Nissan Serena offers drivers a more modern, efficient, and low-maintenance steering experience. While there is no power steering pump to maintain or replace, staying on top of your vehicle's general servicing schedule and paying attention to any steering-related warning signs ensures that your Serena remains a smooth and safe ride for many kilometres to come.
