Yeah these tops crack, The sad truth is the replacement tops might be worse. there are folks that are on their 4th top already. my cracks are small-is like yours I am just going to shoot it with Raptor liner or something, I just can't decide if I want to go black or Desert Sand that is why I haven't done it yet.
My vehicle is built 2023, arrived here in Europe in 2024 and was a stock vehicle until I got it - October 2025. So I have a warranty for some years and will see if the cracks are getting worse. Maybe after a year or more I will eventually claim for new hardtop, just to see the reaction of the dealer here. :)
