I just purchased a 2012 Chrysler 200. I noticed there was excessive vibration in the front end and steering column when braking, so the dealer replaced the front rotors and pads and performed a front end alignment. I still feel the brakes pulsate, but only when I apply braking going down a hill. It feels like the ABS system is engaging slightly. What other repairs can I consider asking for?
