"Brand new" like the dealer told you? The rotors should be bigger, and we should have rear ones, but if OE quality stuff is used then they'll last longer then 5k.
If they're worn by now, you're either hot lapping the car around BIR'* road course too much, or you've been fed some.
Is there snow inside of your wheels? That would make them heavier, and off balance. Also, hot rotors that get splashed by water, or cold snow will warp easy. Other causes can be things like improperly torqued wheels. I always do 25 accross the pattern, then 50 and 75, then the final 100lb/ft.
