I lost power steering the other day completely out of no where when turning off of the highway at high speed.. almost crashed..someone with less upper body strength would have.. I parked the car and turned the engine off to regroup myself then started it up and it was fine.. Drove home.. checked fluid level and replaced the belt.. had not one issue until last weekend the same thing happened again right when I got comfortable it was a fluke and almost took out my couzins Bike..with him on it.. I mean completely dead power steering.. let the car sit that night (no where near home or a jack or a shop) and tried again a few hours later.. still no response.. Next morning i decided to leave early for the long drive home with no PS and it was fine again.. I checked everything I can?? how is this possible to come and go like that.. right now its perfectly fine... I am selling the car but want to resolve this before it kills someone. Ive never heard of a pump doing this and I have no leaks and the belt is not slipping.. its a 2006 GPGXP
