Brake Squeaking Noise problems of the 2010 Jeep Grand Cherokee

Two months after purchasing my used 2010 Jeep Grand Cherokee laredo with about 14,000 miles, my brakes began making an intermittent squeaking noise. When I took my vehicle to the authorized Jeep dealership, I was told that they could not recreate the noise and that nothing was wrong with my brakes. Over the next few months, the squeaking noise became more frequent. The next time I took it in to the same dealership, I was told that this is a common, known issue with Chrysler brakes related to humidity and the use of newer non-asbestos brake pads but that there was nothing wrong with my brakes and the warranty on them had expired after my last visit. This time they sprayed something on the them which worked for a few weeks. The next time I went back to the same dealership with this issue, they turned the rotors which also did nothing to get rid of the noise even though I was charged $180. Since the dealership continued to test my brakes regularly at my insistence and stated that nothing was wrong over the years that followed, I dealt with the noise. I finally replaced the brakes, including adding ceramic brake pads, for $1,200 two months ago. The squeaking noise has not reoccurred as of yet.
