Power Steering Fluid problems of the 2010 Honda Civic

Power steering not responsive power steering noise and fluid leak.

Bought demo 2010 Honda Civic ex in December 2010, so it was virtually new. Problem began occurring around the beginning of September 2012, when the mileage of car was approximately 53,000. Upon ignition, the noise coming from the engine was a higher-pitched whir than I was accustomed to. This higher-pitched whir would worsen as I accelerated and as I turned corners. Thought I just needed to allow the car to warm up. That solution did not work. Took the car into the Honda dealership where I bought the car. I was told that there was a leak in the power steering rack, and that this leak was draining into my wheel boots, by which I'm guessing he meant steering rack boots. I do not have good knowledge of cars. Was told that somehow the drainage of power steering fluid into my steering boots was creating this high-pitched whir. For the few weeks this noise was occurring before I brought it into the dealership there were no signs of leaks under my car. Was told that until the steering boot was completely saturated with power steering fluid that there would not have been any signs of leakage under the car. Fortunately the Honda care warranty covers this repair. Though I don't know if it's the extended warranty that I bought at the time of purchase. Car is being repaired as I type this. Will post again if I learn of any additions.
