What does the noise sound like? Drums are usually silent. Also the rear brakes wear much less then the fronts. Sorry your having an issue so soon with your car. I am at 121k miles and my stock brakes are dead quiet still and my front pads still have alot of meat. My rotors are on their way out though.
If were me I would take off the drum and inspect myself. I hope nissan didn't put crappy parts on the newer cars. I am so impressed with my stock parts I'm considering buying OEM when it is time to change despite the prices being triple of aftermarket companies.
+1 on the quality of the factory brakes (on my 07). I recently did a thorough inspection of my brakes all around (60,000 miles) and the front pads have lots of material left. I anticipate over 100k miles on the front pads. The rears will go longer than that. I have never had a car that got that amount of service from the factory front pads/rotors.
With that being said, it is entirely possible Nissan went with a different supplier (cheaper) for their brake parts in the recent past, which could affect wear and noise in a negative way.
Back to the topic of brake noise. I had some brake noise front and rear prior to my inspection. What I found was dry (no lube) on the caliper pins, and the contact points on the back of the pads. Also the rear brake noise was a faint squeak when letting off of the brakes. I applied high temp brake grease to the contact points where the rear shoes contact the back plate, and I lubed the caliper pins and contact points on the back of the pads.
No more noise and excellent pedal feel.
