Sorry to hear of all the issues.
I too have suffered the brake issue, Front brakes have been replaced twince by Chrysler, and the rear have been replaced twince, once by Chrysler and once by me. After replaceing the rear brakes myself, I am lesss then thrilled with the design of the rear brakes. I will tell you that I will not buy anouther Journey, these brakes just plain suck and nothing has been done to fix the issue.
My Journey has 24,000 miles at this point.
Other then that, I have been more then happy with my Journey, I love the ride, power and room for our twin boys and all their stuff that needs to carted around. And I love the look of the Journey....Almost three years that I have had mine and she still looks damn good! People can;t belive me when I tell them it is a 2009.
