Power Steering Fluid and the 2015 Mitsubishi ASX: What You Need to Know

The 2015 Mitsubishi ASX is a popular compact SUV known for its practicality and reliable performance. When it comes to power steering, an important question for many owners is whether their vehicle uses power steering fluid and how to look after it. After referencing technical sources and manufacturer specifications, it turns out that the 2015 Mitsubishi ASX does not use conventional hydraulic power steering fluid.

Instead of a hydraulic system that requires power steering fluid, the 2015 Mitsubishi ASX is fitted with an electric power steering system, often abbreviated as EPS. This means that the steering assistance is provided by an electric motor controlled by sensors and the vehicle's computer, rather than a hydraulic pump and fluid circuit.

The use of electric power steering rather than hydraulic power steering fluid in the ASX offers several advantages. For starters, it reduces maintenance needs because there is no power steering fluid to check, replace or leak. Without fluid, there is no risk of fluid contamination or degradation over time, which in traditional systems can cause problems like pump failure or noisy steering. Electric power steering is also more fuel efficient as it doesn't rely on the engine-driven pump that runs constantly in hydraulic systems.

With the 2015 Mitsubishi ASX relying entirely on electric power steering, it means owners can skip one of the regular service tasks that come with conventional hydraulic steering systems. This helps keep servicing straightforward and costs down, with fewer fluids to replace and fewer components to wear out.

However, while the ASX's steering system does not use power steering fluid, that doesn't mean it is completely maintenance free. Like all EPS systems, it relies on electronic components and sensors that occasionally need checking, especially if any steering issues arise. Regular vehicle servicing can include diagnostics to ensure the electric power steering motor and related parts are working properly, but there is no fluid level or fluid quality to monitor.

For owners used to hydraulic power steering, it's helpful to understand exactly what power steering fluid does in those systems and why the ASX does not require it. Conventional power steering fluid acts as a hydraulic medium, transmitting the force from the steering wheel through a pump, hoses and valves to assist turning the wheels. It lubricates components and helps dissipate heat generated during steering. Over time fluid can degrade, requiring flushing or topping up.

Because the 2015 Mitsubishi ASX uses electric power steering, this whole hydraulic circuit and the fluid it uses are replaced by an electric motor and sensors. The motor applies torque directly based on input from the steering wheel and vehicle speed data, eliminating the need for fluid and the hydraulic hardware that goes with it. This system design is simpler from a fluid maintenance perspective and can improve reliability.

Owners should still be keen on regular servicing and inspections. If there are warning lights related to steering or if handling feels unusual, it's a good idea to have the electric power steering system checked promptly. While fluid replacement is not a concern, electrical faults or sensor issues can still affect steering performance and safety.

In short, the 2015 Mitsubishi ASX is one of many modern vehicles that has moved away from traditional hydraulic power steering, eliminating the need for power steering fluid altogether. This shift reflects broader automotive trends prioritising efficiency, reliability and reduced environmental impact. So, if you are a 2015 ASX owner wondering about power steering fluid maintenance, you can breathe easy knowing you won't need to worry about fluid top-ups or flushes for your steering system.
