I'm a bit late, but I just received my n5 back from LG, for a screen replacement (not warranty, shattered). In my case I had to pay for shipping to LG (tracking and sig required). The tracking page they have is updated fairly quickly, and email notices came quick too, ie "it's not covered under warranty, how do you want to pay?" kind of email. I talked to LG reps at the start of the process (to get an RMA) and to pay after they looked at it, it was painless and quick. I have to give a kudo to them as it as a fairly painless experience, except for being without a phone for 10 days. They did ship it back via fedex home, and it looks like it was by truck based on the fedex tracking page. The repair facility is in Fort Worth TX, I am in Minneapolis, fwiw.
