Don't hold that one agenst the X5, it's a drag to have that happen, but realisticly that failure was not due to poor quality or design, just bad luck that something managed to works it's way into the intake of your A/C. I am not sure how something gets past the pollen filter, but I have pulled some weird stuff out of vents. I found a couple of those little green army men in a vent one time.
