Recently brought in my 2010 Ford Taurus to the Local Ford dealership as the power steering went out. They did checked it out and said in addition to the steering pump, the front lower control arm bushings are worn/torn and the steering rack needs replacement. I had them replace the steering rack and front control arms 4 years ago (15k miles ago). Seems like some shoddy work or parts as I do imagine that those parts should not need replacing every 15k miles.
