That's annoying, but it's so similar to the OP's damage that it makes it more likely the factory is scraping that are putting the taillights in than the OP got some re-sprayed car.FWIW my car had similar paint issues when I picked it up from the dealer last year. The dealer had clearly preformed an absolute crap buff job and there was white buffing compound leftover in most of the cracks/crevices of the car. Luckily all of the white came off relatively easily, just took time and patience to get to it all.
As for the area of paint near the taillight, unfortunately despite multiple people at the dealer verbally telling me it would get taken care of under warranty I'm still waiting. The only good news about it is that you don't really notice it unless you're looking for it, but it obviously is still disappointing how poorly the dealer has handled this situation.
Do you mind calling out what dealer is jerking you around? I'd like to see more people share which ones are good and bad here.
