On our 09, had to replace the pads and rotors before 20k. Brakes were terrible on the earlier models. I think they went to bigger disks in mid 2012 or something like that. I'm at just around 60k on our 2013. Will need to replace them soon as they are starting to vibrate a bit when braking. Pads are still good for probably another10k, but the rotors need to be turned or replaced. Kudos to FCA. First vehicle I've ever owned where I had to replace the tires before the brakes.
