2019 Sierra 1500 SLT CC - Tailgate Alignment Problem

[hijacker]

The tailgate on my new 2019 GMC Sierra is misaligned causing the left lower corner to rub against the quarter panel. The dealer's service center is going to look at it to see what is needed to make the repair, but I don't see any way to adjust the seams between the tailgate and the quarter panels.  Even if they can't make the seams uniform on both sides, I'll be happy if they can just create enough space on the lower left to keep the paint from rubbing off. I've included pictures if anyone has any advice. Thank you.

Probably a dealer lot accident and they did a poor repair. It needs to  go back to the body shop. Might have to replace the quarter panel on that side.

Lol here’s what they’re going to do. Remove the tailgate, take a 2x4 and a hammer and give that part of the quarter a whack to open the gap. If they’re good they’ll use tape. Perfectly acceptable repair technique.
