I let the dealer do the front brakes on our 09 at @12000 miles. Not long after the rears started causing a vibration and the fronts as well. I replaced everything myself (rotors/pads) using a quality aftermarket brand and had no more brake issues for the next 70,000 miles. If you keep replacing the factory junk with factory junk, you will continue to have brake problems. This is not a Chrysler specific issue. Many car manufacturers, in their haste to save weight and reduce costs are cutting corners. Thinner rotors (which warp early on) saves weight and costs. It took them awhile, but Chrysler finally started putting beefier brakes on the Journey. The brake hardware (rotors, calipers, pads)on my 2013 are gigantic compared to the ones on the 09. Don;t know anything about a class action lawsuit though. I imagine that would not likely go very far.
