Just hit 2000 miles, no problems at all! Averaging 21 mpg around town and 27.5 on HWY.
What gear ratio did you get? Will be mostly cruising back and forth to work in the 70s range and got stuck with the 3.92s since it isn't on the order sheet I got from the dealer.I am also right at the 2000 mile mark too. So far no complaints. Averaging about 21 mpg in city driving, and 26.8 on a trip up to N Florida, steady 75 on highway and 60ish on county roads.
Had to fill the DEF tank because dealer delivered it on 1/2, but gave me a $50 voucher to auto zone to purchase it.
