Well, for me, it took 240,000 miles in 10 years for 1 very cold night in ND to make the crack. Although it is an inherent design flaw, corrected by redesign a few years later, really what car manufacturer doesn't have something happen that ticks off an owner?
Let's be reasonable, I have replaced almost nothing on this vehicle except the radio/cd player, save wear parts like wheel bearings, struts, etc, and 1 alternator. I'm 900 miles from home now with it, use it for work, and have no intention of replacing it until at least 300K. The body looks great, and it runs like new. So I think I will invest in a new panel, and smile.
