2003 Toyota Highlander-limited (v6): power steering pump fluid lines corroding and leaking fluid; thereby causing failure of pwr-assisted steering at any speed. In Jan-Feb 2010, my Highlander exhibited significantly reduced steering ease at intermittent periods. Highest safety risk occurrences were at (1) hwy speeds, and (2) city traffic speeds when accident avoidance handling was required. A dealer in frederick, MD diagnosed the prob as thoroughly corroded pwr steering pump lines. They replaced the lines at my cost. The vehicle had only 56k miles on it.
