Power Steering Fluid in the 2017 Lexus IS: What You Need to Know

When looking into the 2017 Lexus IS and its power steering system, it's crucial to understand whether power steering fluid plays a role in this vehicle. Unlike many older or traditional vehicles that rely on hydraulic power steering systems complete with power steering fluid, the 2017 Lexus IS does not actually use power steering fluid at all. This is because the model comes equipped with an electric power steering system, commonly known as EPS.

The transition from hydraulic to electric power steering is a significant change in automotive technology. The EPS found in the 2017 Lexus IS uses an electric motor to assist with steering effort rather than relying on hydraulic pressure generated by fluid and pumps. This means no power steering pump, hoses, or fluid reservoir exists in this setup, making power steering fluid completely irrelevant for this particular vehicle.

So, why would Lexus opt for an electric power steering system in the 2017 IS? There are several reasons behind this shift. First, EPS systems are generally more efficient. Hydraulic systems run off engine power to turn the pump, which can add to fuel consumption. By contrast, the electric motor in EPS only uses power when steering assistance is needed, improving the vehicle's fuel economy.

Another benefit is reduced maintenance. Hydraulic power steering systems require regular checks of power steering fluid levels and quality. Left unchecked, dirty or low fluid can cause steering issues or damage to components such as the power steering pump or steering rack. Since the 2017 Lexus IS does not have any of these parts or fluid, owners can avoid this extra layer of upkeep.

Also, electric power steering allows for more precise control and can be finely tuned by the vehicle's computer systems. This enhances driving dynamics and safety features, such as lane-keeping assist and adaptive steering technologies, which are often integrated with EPS systems but impossible with traditional hydraulic setups.

If someone owns a 2017 Lexus IS or is considering purchasing one, it's good to know that there is no need to fuss about power steering fluid at any stage. There's no reservoir to check, no fluid to flush or replace, and no leaks to worry about in the steering system. This can make servicing the power steering system simpler and often cheaper over the vehicle's lifetime.

For those familiar with older cars, keeping an eye on power steering fluid is a common maintenance task. Typically, owners would check the fluid regularly, watch for discoloration or a burnt smell indicating the fluid is degrading, and replace it according to the manufacturer's recommended schedule, often every 50,000 to 100,000 kilometres. However, since the 2017 Lexus IS uses electric power steering, these steps do not apply.

That said, while the EPS system itself requires minimal servicing, it's important to keep the steering components in good condition. Regular tyre alignment checks, suspension inspections, and avoiding impacts that could damage the steering rack or tie rods all help maintain smooth steering performance. If the electronic power steering motor or sensors develop faults, these typically require diagnostic equipment and professional repair.

In simple terms, owners can think of the EPS in the Lexus IS as a smarter, cleaner, and low-maintenance alternative to older power steering systems. It delivers the same help with steering effort and improves the driving experience without the hassle and potential issues related to hydraulic fluid maintenance.

So, when planning servicing or routine checks for a 2017 Lexus IS, there is no need to add power steering fluid to the list. Instead, focus on general vehicle care and ensure the electric steering components and related electronics are inspected if any steering performance issues arise. Dealers and qualified mechanics familiar with Lexus vehicles will know how to troubleshoot and maintain the EPS system, ensuring it stays functioning smoothly.

In summary, power steering fluid is not used on the 2017 Lexus IS because the vehicle is equipped with an electric power steering system rather than a hydraulic one. This modern setup improves efficiency, reduces maintenance needs, and contributes to the overall driving enjoyment that Lexus aims to deliver with this popular model.
