Yes, I had two cracked radiator in the upper left section. There was an updated radiator release around August 2008.
I doubt it's do to running hot. I think hitting a speed bumb/dip, potholes, or maybe very hard braking may be the cause. Add hard landing from wheelies if you're into that too. In my case, I remember scratching my belly pan on a speed dip about a week before I started noticing the telltale signs of coolant splattering on the windscreen.
