my ones leaking as well. but its really weird. i fill it all up including the overflow bottle to the MAX point. i drive for awhile (20 min)...have a look to see if there are any leaks. nothing...

i pull to the side of the road. pop the hood to see the overflow bottle has been strangely filled all the way to the top. i get home and park it. i come out a maybe 3 hrs later to see that i have NOTHING in both radiator and overflow bottle...

what's the problem? is my radiator busted? need help...don't want to spend $220 for a new radiator.
