Mine did the same, at 6 weeks. My 2004 TJ top Has never had an issue. There is a big difference in the zippers.
TBP put me in touch with Larry at Rampage 657 212 3045. Filled out a form, supplied a couple of pictures and my receipt. My new top is on the way.
I wont even be taking it out of the box. Its going straight to the Tent and awning guy that recovered my boat seats for a zipper upgrade.
