One of the things is never let your brake dust bake on the rims and wash your rims (soap & water) before you wash the rest of the car.

Last but not least, bring the issue to your service manager. If you don't get a response them got to FB.

Go to FaceBook under Nissan North America, do a friend request and go to the Discussion Thread and open a Topic, your will get a message real fast, believe me.

Also PM me, I have some email addresses that will get you some answers and results if you cannot get your issue resolve at the lower level.
