Was going to post a similar question to folks...glad to see someone beat me to it.
I'm expecting mine in Sep/Oct and am also hoping that most of the production issues have been addressed. We hear about the problems on this forum (and rightfully so)...we don't hear about the Xs that were delivered without issues, which makes it hard to gauge whether QA/QC is improving or not, and at what rate.
The windshield issue is of concern...it doesn't seem like there's any good answer to it other than live with it. To the OP's original question - does anyone have any insight if the problem is getting worse / better as production has been ramping up, or whether it's still as substantial.
I love the X...and can't wait to get ours. I'd be nice to have more transparency (from Tesla...and yeah, unlikely) or line of sight from the people in this forum on what to expect from a quality perspective.
