Power Steering Fluid and the 2016 Subaru Legacy: What You Need to Know

The 2016 Subaru Legacy is a great vehicle known for its reliability and smooth driving experience. When it comes to power steering, many people wonder about the role of power steering fluid in this car. In this case, the 2016 Subaru Legacy does not actually use conventional power steering fluid. Instead, it relies on an electric power steering system, which means it does not have a hydraulic pump or fluid reservoir like older systems.

So why is there no power steering fluid in the 2016 Subaru Legacy? The answer lies in the type of steering system it employs. Traditional power steering systems use hydraulic fluid to assist with steering by creating pressure in hoses and pumps, which helps reduce the effort needed to turn the steering wheel. These systems rely heavily on the condition and maintenance of the power steering fluid to function correctly. However, the 2016 Subaru Legacy has moved away from this older technology.

Subaru opted for an Electric Power Steering (EPS) system in this model, which uses an electric motor to provide steering assistance rather than a hydraulic pump and fluid. This newer system comes with several advantages. It is generally more efficient because it only uses power when steering assistance is needed, which can help improve fuel economy slightly. Additionally, since there is no fluid or hydraulic components involved, there is less maintenance required and fewer chances for leaks or fluid contamination that could impact steering performance.

Given this setup, there is no need to check, replace, or top up power steering fluid in the 2016 Subaru Legacy. That maintenance task simply doesn't apply because the power steering fluid system does not exist in this vehicle. Instead, the EPS relies on electrical components that are usually very low-maintenance but do require proper servicing of other parts such as the battery, wiring, and sensors to ensure everything works as intended.

For those familiar with older cars or those who might be servicing other vehicles, understanding why some cars do not use power steering fluid can help prevent unnecessary confusion. If you own a 2016 Subaru Legacy, any mention of power steering fluid can be safely disregarded. The vehicle's user manual will make no reference to hydraulic fluid or power steering fluid changes because it is simply not part of the system.

That said, power steering fluid is an important component in vehicles equipped with hydraulic power steering systems. It acts much like the blood in your car's steering system, providing the necessary pressure to help turn the steering wheel with ease. Over time this fluid can become contaminated with dirt, metal shavings, or moisture, which can lead to decreased steering performance or even damage to pumps and seals. Regularly checking and replacing power steering fluid can keep that system running smoothly and help avoid costly repairs.

While this maintenance is crucial for vehicles that use hydraulic power steering, the 2016 Subaru Legacy owners have the advantage of an EPS setup which eliminates this particular maintenance chore. Instead, it is wise to focus on standard preventive maintenance practices such as checking the condition of the battery, keeping electrical connections clean and dry, and having the overall steering system inspected during routine servicing.

For drivers who have experience with older vehicles, it's worth noting that electric power steering systems generally have fewer moving parts and no fluid lines, meaning there's less chance of leaks or the need for fluid flushing. This can translate into fewer worries and a smoother ownership experience. However, because EPS relies on electronic components, if a fault does develop it generally requires professional diagnostics and repair rather than simple fluid replacement or topping up.

Summing it all up, the 2016 Subaru Legacy simply does not require or use power steering fluid due to its electric power steering design. This change reflects a broader trend in the automotive industry toward more efficient and low-maintenance technologies, prioritising fuel economy, reliability, and user convenience.

If you do own or service a different Subaru model or another make of car that uses the traditional hydraulic systems, regular power steering fluid maintenance is still very important to ensure safe and easy steering control on the roads.
