Adaptive Equipment problems of the 2013 Honda CR-V

I purchased a 2013 crv in the beginning of 2013 with VIN # [xxx]. With about 6,000 miles after the first oil change, the vehicle starts making a creaking noise when pushing and releasing the brake. I went to the dealer on 11/11/13. A technician was able to duplicate the problem. The second visit to the dealer is on 11/25/2013. A master technician was able to duplicate the problem and identify the noise does not come from the braking system but from the rear differential system. The dealer made a phone call to Honda tech line and was told to hold on the fix and wait for Honda to do more investigation. The dealer said Honda will send me a letter in the near future. I waited for the response from both dealer and Honda for more than a month and heard nothing. The dealer told me to contact Honda directly. I called Honda in end of December 2013, and heard back from them in 1/3/2014, a Honda representative named [xxx] in 1-800-999-1009 [xxx] called me back and told me that Honda is not going to fix the problem and replace any parts but will do more investigation. He mentioned that the investigation will last for 2 to 3 years. Also Honda is not considering the rear differential system is failed or defective, because the computer did not notify them such part is failed. [xxx] refused to give me more information and did not want to issue a statement or letter to me to describe the problem and what further investigation will Honda do. [xxx] keeps saying that he is not an engineer to answer any technical related questions. The decision made by Honda is no repairing or replacement to any part to fix this problem.
