My 2012 Overland 4x4 started doing this within the first week of ownership. I didn't hammer the brakes when stopping and tried to do a proper vehicle break in.
When I first went to my dealership to have them fix the squealing brakes along with some other issues, their cracker-jack
technicians said they weren't able to reproduce the problem. I jumped in my vehicle and reproduced it on the spot. The Service Manager then told me a story about "Glazed Brakes". He recommended a few HARD STOPS to try and fix it.
5,000 miles later and the problem was still there.
The dealership finally replaced the pads along with a MUCH NEEDED Alignment & tire rotation. The problem with the squealing brakes appears to be gone for the most part.
