Try a different set of pads. I would guess they put on lifetime pads. This is alright but the longer the life of the pads the harder they are and the more they tend to make noise when you hit the brakes. Try a set of OEM pads or a set of raybestos or performance friction carbon metallics. I will bet that the noise goes away and does not return. Also make sure to lubricate the bolts and slides on the brakes with brake grease. They could be binding slightly.

I also have one question, I thought the Pacifica was warranted for 3years or 36K miles all except the brake pads? The dealer should have done everything for free with the exception of the cost for the brake pads! And the last time I checked it only cost about $12 per rotor to turn them down at any machine shop. Let's add this up, new pads $60, machine rotors $24, one hour labor $70 total cost $154. Getting screwed by the dealer $400!
