A couple of months ago a light vibration started occuring when stationary.

Over the past week it's gone completely down hill. It's started grinding quite violently then the power steering cuts off and dash light appears.

Most of ghe time i cut the engine then restart and it's ok but only for a while. Seems to cut out when ever it wants.

Battery is pretty much brand new so any ideas what else it could be ?

It's possible the power steering needs recalibrating
