Brake Disc Pads problems of the 2016 Nissan Sentra

On 11/02/17 brought the car in for the brakes and service said they couldn't get it to squeak while it was at the shop. Was in for 1 day for service. Now its 1/16/18 brought the car back in again and service can hear grind/squeak sound mileage under 12,000 miles and shop wants to shave the rotors on my car and replace brake pads. I do not want my rotors shaved as that makes it one less time I can do that in the future. So service replaces with new Nissan rotors and brake pads. Car in shop for 10 days now its 8/16/18 car has less then 5,000 miles on Nissan factory parts and brakes are making noise again. Mason in service wants to shave my rotors and replace brake pads but Nissan does not want to cover them under warranty. I tell them its ok to shave rotors this time but feel Nissan should have better parts. With the few miles that are on the brakes and rotors. Car has less then 16,000 miles on it. Car in shop for another day. Nissan has a known problem with these brake pads they are using mason the service manager said Nissan has a bulletin about the noise there brakes make. Well I would have liked to know that when I was purching this vechile. As of writing this letter the brakes started to squeak again. I am tired of driving this car in public and it sounding like a old cop car or taxi cab. I bought a new car for a reason! so in closing the car has been in the shop 12 days so far, has had new brake rotors and pads replaced twice and the car has less then 17,000 miles on it now. I guess I expected to much when I purchased a car for $25,000 that it would not have any problems and Nissan has proved me wrong. What I would like Nissan to do is purchase this vehicle back from me, with a credit so I can purchase a new Nissan with no problems.
