RAS545

I recently brought my 545 into the local dealer for its last maintenance and warranty prior to 50K miles.
I had specifically asked to have the brake system checked for wear and replace any worn parts prior to the warranty expiring.

Tonight, I had learned that the car will need new rotors & pads (90% worn in front & 95 in rear) I have only driven 1200 miles since the last maintenance. Should I address this with BMW? I feel with the amount of wear, these parts should have been replaced under warranty.

Any suggestions would be helpful. Thanks
