Happy Sunday everyone!

Bought a SRT6 last year with 25,000 on it. Owner said he had just replace the convertible top (which looked fantastic) in March of last year through the forum vendor BAS from England, I believe part of a group buy.
I noticed today that on the bottom left side, the window stars separating from the fabric. I also heard there is a lifetime warranty on these tops for exactly that issue. Does that carry over to a new owner? I'd be pretty upset if I have to purchase a new top already.
Also, would you even consider the warranty or is that a fairly easy fix? Maybe attach it myself?

Here are some pictures.
