Brakes faulty. Brand new pads installed last week all around adjusted and dealer claims all is well but problem still exists. It takes an extreme amount of force applied to the pedal to stop this vehicle, noticed at 35k. Dangerous and not easy to get used to. In addition, windshield leaks on the top drivers side and the rear right door handle is failing on back dutch doors now at 65k. Also, both power door actuators on the drivers side and the passenger side failed completely at 34k.
