Well mine is leaking again. Got a leak in the middle directly above the slider and no visible cracks. Seems to be a small leak so far.
The first time it leaked was in June 2023, fixed under bumper to bumper warranty by replacing the window. At that same time I replaced the stop light as well with the version that has the rounded gasket. I figured it would happen again
So now my choice it to contact the dealer because I believe they told me the replacement window has a 2 year warranty. Or I could try the DYI sealant. I plan to call the locally owned auto glass shop to see if he knows much about this issue and see if can get info on the "Ford" style glass or maybe just go with the a solid window and call it done. I'd hate to lose the slider but would welcome not having to think about this ever again.
edit: just realized this time the water is running down on top of the plastic frame whereas the first time it was behind the plastic. Maybe it's the 3rd brake light instead?
