The car is fitted with EHPS electro-hydro-power-system . With the engine running , idle or cruising, after some time not much I have NO power steering.
Steering, Suspension, Brakes, Wheels & Tyres
Could be the EHPS pump , quite common .You could check the alternator output and battery condition .Best to get it scanned rather than guess and fit parts maybe not needed .
The problem occurs when fan blower is on,auto or not regardless of the A/C is on or off. New battery fitted alternator checked .ok,I have scanned the car ,nothing wrong . Is it possible an electric device to malfunction and over consuming current leading to EHPS failure?
