The dealer replaced the front pads and rotors under warranty on my '09 Journey at 20k miles as well. I replaced the rear pads at about 35K miles with ceramic pads. About 60k miles on it now and all is still well. In the past I have owned Toyota's, Honda's, Subaru's and currently own a '92 Miata and a '03 AMG C32. Besides the relatively minor brake problem(to me) the Journey is one of the best cars I have ever owned.
