Power Steering Fluid in the 2021 Lexus IS: What You Need to Know

If you are curious about the 2021 Lexus IS and its power steering system, one common question that often comes up is whether this model uses power steering fluid. The straightforward answer is that the 2021 Lexus IS does not use traditional power steering fluid like you might find in older vehicles or in hydraulic power steering systems.

The reason behind this lies in the type of power steering system fitted to the 2021 Lexus IS. Instead of a hydraulic setup, the vehicle features an electric power steering system, commonly referred to as EPS. Electric power steering relies on an electric motor controlled by the car's computer rather than a hydraulic pump driven by the engine. This electric motor provides the assist to the steering, making it lighter and easier for the driver to turn the wheel.

Since the electric power steering system does not use pressurised hydraulic fluid to assist steering, there is no power steering reservoir or fluid to monitor or replace. This eliminates the need for power steering fluid maintenance altogether, which is a bonus for owners who want to reduce the number of fluids their vehicle needs during servicing.

EPS systems have become more common across many new car models due to several advantages. They improve fuel efficiency slightly since there is no hydraulic pump constantly running off the engine, and they also allow for more precise steering control and integration with driver assistance technologies. Additionally, maintenance is usually simpler without the concern of leaks, fluid cleanliness, or fluid levels dropping over time.

For a 2021 Lexus IS owner, this means no need to worry about checking or topping up power steering fluid. Any steering-related service will focus on the electric system, including inspecting the EPS motor, wiring, and related sensors, rather than dealing with fluid changes.

That said, it's still important to maintain your Lexus IS according to the manufacturer's recommended schedule. Routine inspections by a qualified technician will ensure that the electric power steering system is working perfectly, along with other critical components like brakes, tyres and suspension.

For those who may have owned older Lexus models or other cars with traditional hydraulic power steering, the switch to electric power steering might feel different at first but is generally regarded as an advantage due to its convenience and reliability. You won't find power steering fluid listed in the 2021 Lexus IS maintenance book, and there is no need to add it at any point during the vehicle's life.

In essence, the 2021 Lexus IS embraces modern steering technology with an electric setup, making power steering fluid obsolete. So if you're maintaining or purchasing this vehicle, put away your fluid checks and enjoy the benefits of a more efficient and low-maintenance steering system.
