Purchased a Limited in Feb '11. Just passing 44k miles. I am outside sales and drive the western US. I have the same complaints on Sync though the new software is significantly better than original. With K&N filter and summer fuel I can get up to 26mpg with air. Winter fuel I am in the 24mpg range on open road at posted speed or close. I have driven this car in horrible conditions with amazing grace. One of the best cars I have driven. Comfort on long trips is excellent. Handling superb wet or dry. Comparison to my last vehicles better in most ways disappointing in few others. Before my Edge I wore out Buick Enclave, Porsche Cayenne, Mercedes M320. I would buy the Edge again but ask me next year when I have 75k on the odo I may have changed my mind. I am sorry to read the distress of rdebruin but I can say for sure he is much better off with the Edge than a Cayenne S.
Cheers,
