 Bought new three years ago and here's what I noticed. When I hit approx. 65 mph, cowl rattles. High pitch is noticed at 62 mph too. Dealer tried five times but still could not fix it. Driver side door had to be re-aligned because it was improperly installed. Power sliding door was rubbing against main body of the van--body shop took care of it. When the weather is cold, the engine idles high above 1700 rpm for 5 min. before settling down.  Dealer says it's normal but did not notice this on other rental minivan. 19 mpg overall. Bought this over Honda Odyssey because it was quieter but 3.3L is inadequate for this heavy van.  Overall, this is a decent van but body integrity is very poor.
