A different rear window problem.

[GN2018]

So today I noticed that my rear window defroster is not working.  The middle section, the slider part, did not clear the ice from the window.  The rest of the window cleared just fine.  Of course now my dilemma is whether or not to get it fixed.  I got my 2021 in March and so far my window is not leaking.  I don't like the idea of not getting something fixed, but I really, really don't want them replacing the window given the issues with the leak that we all know too much about.  My thought has been that if my window ever did leak that I would get the solid window even if I had to pay for it.  Now I'm wondering if I should just go ahead and get it now.  Or, should I wait for the window to start leaking and then deal with it.  FWIW, the middle of the window (the slider) not defrosting is not a big deal, but something being broke on a new truck that's under warranty is hard to just ignore.  What would you do?

Id make them fix it. I didnt pay for something broken. But thats just me and Im OCD. If my window happened to leak after that, then they would just have to fix that also. It may not come to that. If there is something wrong with it maybe they can just replace the center section instead of the entire assembly.

I'd let them fix it, they replaced my rear window 2+ years ago and not an issue, they sent mine to a Glass shop and had it done.

Just the middle section is replaceable. When the dealer ordered my replacement window for the leaker. They sent just the middle glass piece when it showed up the 1st time.
