Hey guys I'm new to site and I just bought my second Lexus yesterday. It has 247000 original miles. I drove the car before I bought it and heard I little popping noise when I turned the wheel just a little bit. Well I let the car sit overnight and was backing up this morning and I had no power steering at all. I looked at the pump reservoir and there was a little bit of fluid around the resivor but it was full. Has anyone had this problem?
