2 Hydraulic Power Assist Steering System problem

Failure Date: 09/08/2005

I have owned my 2004 chevy Silverado since sept. Of 2004 without any problems. Just recently, however, my power steering is failing at speeds below 10 miles per hour. I have taken it to the dealer and have been informed that this is common for the car and that there is nothing they can do. I was presented with a bulletin stating as much. I believe that power steering loss at any speed poses a significant risk to me, pedestrians, and property. I would like to see this problem resolved. My understanding is that there are many Silverado owners experiencing this problem. Failure is now a daily occurrence. Please advise.
