Yes. The Lexus RX 350 currently uses electric power steering (EPS).
In practice, EPS has become standard on the latest RX 350 models, replacing older hydraulic systems. However, some early generations and certain markets relied on hydraulic steering, with EPS phased in over time and now universally used in recent model years.
What is electric power steering and why it matters
Electric power steering uses an electric motor to assist steering rather than a hydraulic pump powered by the engine. This offers benefits such as improved fuel efficiency, simpler packaging, and the ability to tailor steering feel through drive modes and safety systems. For most drivers, EPS provides smooth, consistent assistance and integrates with other driver-assistance features like lane-keeping assist. Some models allow varying feels with different driving modes, which can influence steering effort and response.
Which RX 350 models have EPS?
Here's a quick timeline of steering systems used across RX 350 generations.
- Current-generation RX 350 (model years 2016–present, including updates through recent refreshes): Electric Power Steering (EPS) with variable assist and drive-mode integration.
- Earlier RX 350 generations (pre-2010s to mid-2010s in some markets): Hydraulic power steering was standard; EPS was gradually adopted and became the norm by the late 2010s.
In short, if you’re looking at a modern RX 350, you’re dealing with EPS; older vehicles, especially outside North America or before the mid-2010s, may have hydraulic steering.
Summary
The Lexus RX 350 uses electric power steering in its latest iterations, with hydraulic steering found on older models in some markets. When shopping, verify the steering system by model year and market to be sure.
