"has adjusted the seam so it is no longer applying that pressure" Translation: He got a hammer and a grinder and cleaned it flat like it SHOULD have been from the start.
Good luck, here's hoping. You definitely had a defect happening that it kept breaking at the same exact spot. I haven't tried getting mine done yet, but since I'm out of warranty it will be an insurance thing anyway. I know Tesla aren't going to pay for it at all.
I'm more annoyed that now I have to get those 3 acres of glass tinted again, that was like $300 just for the windshield piece on my sister's X (mine was already done when I bought it) and they had a bugger of a time getting it to fit right.
