Power Steering Fluid in the 2017 Subaru XV: What You Need to Know

The 2017 Subaru XV is a popular compact SUV known for its practicality, all-wheel drive capability, and reliable performance. When it comes to its steering system, many drivers wonder if the vehicle requires power steering fluid and what role it plays, if any, in everyday maintenance. After reviewing technical resources and official Subaru documentation, it's clear that the 2017 Subaru XV does not use conventional power steering fluid because it is equipped with an electric power steering system rather than a hydraulic one.

Traditional power steering systems rely on a hydraulic mechanism powered by an engine-driven pump to provide assistance when turning the steering wheel. These systems use power steering fluid to transfer pressure and lubricate components, making steering lighter and easier. However, the 2017 Subaru XV features an Electric Power Steering (EPS) system, which eliminates the need for hydraulic fluid altogether.

Electric power steering uses an electric motor to provide the assistive torque, often controlled by sensors that detect steering input and vehicle speed. Because it is electrically driven rather than hydraulically, there's no reservoir or hoses filled with fluid for pressure transmission. This design choice reduces complexity, improves fuel economy by removing the belt-driven pump load, and minimises maintenance requirements related to fluid checks and replacements.

So, why is there no power steering fluid in the 2017 Subaru XV? The move to electric power steering reflects broader trends in automotive engineering that favour efficiency, lower emissions, and enhanced reliability. Hydraulic systems inevitably require fluid changes and leak repairs, EPS avoids these issues.

With no hydraulic pump or hoses, the electric motor and associated electronics handle the steering assistance. This means drivers of the 2017 Subaru XV will not need to worry about checking, topping up, or replacing power steering fluid at any stage. Maintenance focuses instead on ensuring the electrical components and sensors remain in good working order.

That said, it's still essential to keep the steering system healthy, even for an electric power steering setup. While there's no fluid to maintain, the system relies on components that should be checked for proper operation during regular servicing. A technician might inspect the steering column, electronic control units, and wiring connections to confirm everything is functioning correctly. Additionally, wheel alignment and suspension condition can impact how the EPS performs, so these remain important areas for routine vehicle care.

For anyone new to the 2017 Subaru XV or coming from older vehicles with hydraulic power steering, it's worth noting that electric power steering can feel different - it's often quieter, more precise, and may offer variable assistance based on speed, offering more help when parking and less at highway speeds. This modern system is a key contributor to the vehicle's overall fuel efficiency and reduced maintenance overheads.

While there's no power steering fluid to worry about, it is still a good idea to be aware of warning signs that might point to steering system issues. Some symptoms include unusual noises when steering, difficulty steering, or warning lights on the dashboard related to the steering. Any of these signs should prompt a professional inspection for potential electronic or mechanical faults.

Since the EPS system is integrated and electronically controlled, repairs or component replacements are typically more specialised than the relatively straightforward fluid top-ups or pump replacements of hydraulic systems. Subaru dealerships or qualified workshops with access to the right diagnostic equipment will be best placed to handle any EPS issues.

To sum up, the 2017 Subaru XV does not use power steering fluid because it comes equipped with an electric power steering system. This system offers improved efficiency, reduced maintenance, and a more modern driving feel compared to traditional hydraulic setups. Drivers can enjoy the lighter steering effort without the fuss of fluid checks or replacements.
