Brake Loud Noise problems of the 2008 Jeep Compass

I've had brake noises from my 2008 Jeep Compass since about 500 miles. I've taken it to the dealer over four times, and they have done nothing to fix the problem. The engine or transmission also makes a terrible noise/vibration when stopped for a light or other situation after it is warmed up. . The dealer said this is normal. I'm approaching 22,000 miles, and I bet they will find the problem when it hits 30,000. We will see if the extended warranty covers this stuff.
