I think I remember reading a similar post here, and the problem turned out to be some type of clips that were inadvertently left in place during the manufacturing process.
Apparently, the windshield is held in place with these clips, and they are supposed to be removed before final assembly.
Maybe these links will help. Note in the first link that there is mention of a TSB for this problem. There is also a link within these links to a similar Yotatech discussion:
