So I finally am getting resolution on this.
Took to dealer and they said they had to send pictures into Toyota because they have never seen it before. Waited. Toyota comes back and says that because they aren't able to discern for sure how this damage was caused and because regional has never seen such an issue before, they would not be able to cover under warranty. However, they would offer to cover half of the cost to replace as a good gesture. Since the part alone is $400+ I declined. I then sent an email to the service manger saying that there are multiple people online with the same exact issue and some have gotten it replaced under warranty. He said that they don't take into consideration forums or any online reports but offered to have a regional tech come and look and made it clear that whatever the tech decides is final(the covering 50% would be off the table). So I finally was able to take it in this week and the regional tech approved the warranty replacement, even admitting that he has seen this once before. His opinion is that this is caused by the way the trim piece is covered during shipment. Either way, a third and final trip to the dealership should finally get this taken care of.
