Yes, we've had our 4.4 for 3 months and 10,000 miles and have done a number of 8-10 hour straight drives with out stops. It takes awhile to find the right seat settings but when you do (ours has the lumbar option, non sport) you'll get out with a spring in your step if you're like us. We've had a couple of minor electrical glitches (the biggest being the rear PDC stopped working) but the dealer has been great even though we bought it 400 miles away from another dealer for less than MSRP and a much shorter wait time.
