I've been getting this high pitch squealing noise, kind of like metal grinding or something coming from what sounds like the back of my wheels. I heard it before and took it to the stealership and they found rocks stuck in between so that fixed it. Now couple of weeks later, I hear it when I apply the brakes. I took it to the stealership yesterday and they couldn't duplicate the noise and found nothing wrong and charged me $65 bucks!! They said they check the front/rear brakes and said they were good, and yet today I heard it again......so I was wondering if anybody knows what the problem could be?

 

Anytime it rains(even dry weather), there's a high pitched squeaking no matter the circumstance with myself.
You're probably going to have to wait until it goes crazy then make a pit-stop at the dealer so they can duplicate it better.

 

I had the same EXACT problem and I took it to a local suspension/tire/shock/alignment shop and they said that my driver's front rotors are scarred from a rock that got stuck in my brake pads. So basically, there's this circle outline (not too deep) in my rotors and so when you brake, there's this opening in your brake pads that don't make contact with the rotors, therefore producing that sound. You can get your rotors resurfaced and the sound should be gone though. But I know what you're talking about and the sound is very annoying. Hope this helps.
