No, I haven't noticed any brake problems, but I seem to recall some other folks posting about either brake pulsing or front-end shake. Can't remember for sure.
Only problems I have are with the A/C not getting terribly cold (although it has hit 100 F every day in Dallas for the past week), and an alignment problem between the driver's door vent and the dash. I haven't had time to go back to the dealer yet for them to look at those, but am planning on it.
