Power Steering Fluid

The function of this fluid is basic: transmitting hydraulic pressure to make steering easy-but achieving a seamless system operation over a wide variety of conditions is not. The fluid must perform consistently in any situation, from sub-zero to triple-digit temperatures, and both ambient and under-hood temperatures. It also must function when the engine is at idle or full-throttle, and under high pressure, all the while providing adequate lubrication to pump and control valve assemblies, maintaining integrity of rubber components in the system, and promoting noise-free system operation. And your fluid has to do all of these things over an extensive period of time!

Over the course of 50,000 miles metal particulate matter and rubber fragments from seals can accumulate over time which is hard on the power steering pump and rack.  This can be identified during inspection.  Infiniti does provide a recommend a power steering fluid change interval.  However, a good rule of thumb is  four  years or 50,000 miles when the vehicle has seen sever driving conditions.
