Power and power steering failure- when it rains or I drive through puddles of water the car looses power and slows. Also when I am driving the power steering stops working and there is a loud squealing noise. I had the dealer look at my Acadia and they said they could readjust the belt guard. This did not work and they said just be cautious while driving. Also the cruise control doesn't coast and the speed increases as you go down hill.
