Brake Squeaking Noise problems of the 2008 Nissan Altima

I would like to report a chronic brake problem I have had with my 2008 Nissan Altima, since the date of purchase in may of 2008. To date, I have had to bring in the car for repairs ranging from squealing noises right down to out and out grinding which began only 3-4k miles after I purchased the car. After the first several repairs, which did absolutely "nothing' as I noticed the brakes squealing still just days after I brought the car in, the car dealership advised me there was a technical service bulletin (TSB) issued which required them to perform a 'complete" brake pad replacement, which included brake pads, rotors and brand new replacements of all other parts that the brakes use. Since that time, the brakes continue to make this annoying squealing noise and when the dealership is questioned about it, they simply revert back to what they told me the very first time I called them about this 3-4 months after I bought the car, which was that this sound was normal with all cars and was nothing to be alarmed about, which sounded totally preposterous to me and was even proven incorrect months later after the initial complaint when they advised me there was that technical service bulletin (TSB) issued regarding this problem which resulted in the aforementioned complete overhaul repair. It was noted that, among other reasons, this occurs as a result of the problem is caused by the semi-metallic pads used by Nissan and/or other cheap or poor quality brake products used. From what I have learned there have been "three" TSB's issued relating to brake problems with the 2008 Nissan Altima as follows: ntb07-003c murano and Altima; squeak noise when brake pedal is pressed. Ntb08-047 Altima: rear brake noise at slow speeds ntb08-057 2007-2008 Altima; front brake noise at slow speeds.
