Had the stuttering issue as well. TSB for a re-flash solved the issue. Also have the intermittent left speaker issue - sounds like its pretty common. I have 60k miles on mine and lifetime MPG is 17.8, some towing and mostly country driving. Nothing spectacular for mileage but its way better than the 5.4 I had before for the same work.
