If you get an '05 Armada, I have read that the majority of rattles/squeaks have been eliminated. As for the brakes, I don't think Nissan has yet to release a permanent fix, but they will continue to temporarily fix the brakes under warranty. I haven't had any drivetrain issues, and have only heard of one or two fluke transmission crap-outs. My biggest gripe is the shoddy materials used in the interior - I have scratches from my console all the way to the floor and wall plastic in the cargo area. But the drive makes up for it in my opinion (although it shouldn't, looking at the price).
