 We've only owned our '05 Sedona for 4 months.  9000 miles on it now.  I was surprised at the "normal" noisiness of the van. A/C compressor is extra noisy when it turns on.  A 'clunking' noise comes from the front end at any small bump in the road.  Sounds like tie rod end bushings, but dealer mechanic says, "drive any '05 Sedona and you'll hear the same thing."  Same said about the A/C compressor.  The seats are not particularly comfortable, but have a nice covering.  I just had the rotors replaced from warping (8000 miles).  My dealer said, "rotors not covered under warranty," a dealer in Illinois disagreed and changed them while I was on vacation.
