Power Steering Pump on the 2013 Lexus IS: What You Need to Know

The 2013 Lexus IS is a popular luxury sedan that blends performance, comfort, and style. When it comes to steering, many people wonder whether this vehicle uses a traditional power steering pump or if it has moved on to more modern steering technology. After checking technical sources and official information on the 2013 Lexus IS, it's clear that this model does not use a traditional hydraulic power steering pump. Instead, the 2013 Lexus IS employs an electric power steering (EPS) system.

Electric power steering systems have become the norm in many modern vehicles, including the 2013 Lexus IS. The EPS replaces the older hydraulic power steering pumps that rely on engine-driven pumps and hydraulic fluid. This modern system offers several advantages such as improved fuel efficiency, reduced maintenance requirements, and a more precise steering feel.

So why does the 2013 Lexus IS move away from the traditional power steering pump? Compared to hydraulic systems, electric power steering systems don't require a pump driven by the engine, which means there's no need for hydraulic fluid or belts that can wear out over time. This not only frees up some engine power that would otherwise be spent running a pump but also reduces the complexity of the steering system. With fewer moving parts and no fluid to maintain or leak, EPS systems typically need less attention during servicing.

Electric power steering systems also allow for variable assist, which means the level of steering assistance can change depending on how fast the car is moving or the driver's input. This feature enhances both comfort at low speeds, like when parking, and stability at higher speeds on the motorway.

Despite the lack of a power steering pump, owners of the 2013 Lexus IS should still be mindful of their steering system's health. Since EPS relies on an electric motor and sensors, issues here are different from those experienced with hydraulic systems. Regular checks during servicing will usually include inspection of the EPS motor, wiring, and connectors to ensure everything is functioning properly. Any error codes registered by the vehicle's diagnostic system related to steering assist should be addressed promptly to avoid steering difficulties.

For peace of mind, it's important for 2013 Lexus IS owners to know the signs that might indicate a problem with the electric power steering system. These can include:

• Steering feels heavy or less responsive than usual
• Warning lights on the dashboard, especially those related to power steering or stability control
• Strange noises when turning the steering wheel
• Intermittent loss of steering assist

While power steering pumps on older or traditional vehicles can sometimes be rebuilt or replaced relatively easily, EPS components often require specialised diagnostics and repair by qualified technicians. This is because the EPS is integrated with the vehicle's electronic control systems.

In terms of routine maintenance, since there is no power steering fluid or pump to service, the 2013 Lexus IS steering system usually only needs periodic inspections during scheduled servicing. Technicians will generally check the steering column, tie rods, and related components for wear or damage, and test the electrical system's overall health. Keeping tyres properly inflated also helps reduce strain on the steering system.

If any steering assist issues are detected, it's best to consult an authorised Lexus service centre or a specialist familiar with electric power steering on luxury vehicles. They have the right diagnostic tools to pinpoint any faults and can ensure that any repairs or part replacements restore full steering performance.

Ultimately, while the 2013 Lexus IS does not use a traditional power steering pump, it benefits from the advantages of modern electric power steering technology. This means fewer parts to wear out, no hydraulic fluid leaks, and better overall efficiency. Owners can enjoy smooth steering with less fuss in terms of maintenance, but must still remain vigilant for any signs of steering issues and address them with professional care.
