...when hitting the brakes. ? What are some things that could be wrong? Rotors? Brakes? Only does it backing up.
 
No matter what brand of car after sitting over night a slight film of rust starts forming on the rotors. Even though you may not be actually touching the brake petal the brakes on all four wheels are designed to "drag" slightly to remove debris (water, dirt and rust.) I'm betting the brakes make no noise whatsoever after driving a few miles forward or reverse.

Next time after the car has been sitting overnight before entering your car, take a flashlight and inspect the rotors for any residue. If they are not shiny and bright the disc brake pads have to actually scrub the rotors for a few minutes to clean them off. I doubt very seriously if the pads need replacement as the car is relatively new. When the time comes however for replacement, specify ceramic based brake pads. They are the cleanest and and do the least amount of stock removal from the rotors.
 
its a build up of dirt and oxidation(like rusting)on your brakes it appears worse in reverse because when your Driving along all day the brakes r working in mostly one direction then the dirt builds up on the other side and you ll notice it in reverse. more common in winter months when its damp and cold also the road salt/grit is a factor nothing to worry about as long as it happens while your brakes r cold and as they heat up goes away you can have the brakes cleaned as ashort term solution but it will only reoccur
 
drake rotors/discs will have surface rust on from sitting over night.it may simply be scraping it off on to the pads...
