I just bought a 2011 5.0SC and debugging the inevitable collection of niggles. Currently wrestling with a problem with the power steering. When the car is cold, the PAS can suddenly and randomly fail to provide assistance on one of the early turns in the journey. Just no effort at all as you try to turn the wheel, always to the right so far. It's seems to go away with a small blip on the throttle but can be quite scary. There are no obvious leaks but have had to top up the PAS fluid. Any ideas gratefully received!
