54k on my 11 Eco. Front steering rack froze up last winter around 27k spent a month in the shop waiting for a back ordered rack but since then no problems at all with anything. Great running truck I think I'll be keeping this one till the wheels fall off. Unless I run into a bunch of money when the new body style comes out lol

70.2 K miles averaging 19.4 mpg since new/ 20.1 non towing
Had the rear slider go out. Have the miss/shudder under load. Have had the total loss of power issue. Have the severe shudder when towing heavy loads and accelerating from a stop. Creaking front end from something cracked on the front shocks that has been brought up here before. Also think I have a 4x4 issue but has not been looked at for that yet. I seem to think there is a lot of wind noise in the cab for a truck this expensive, have not been able to ride in another one and see if it is imaginary or really actually loud, but even when there is no wind outside I hear a lot of wind noise. Sporadic service Advancetrac messages.
Even with the issues, I do like the truck a lot. And the only issue really specific to the Eco I am having is the miss under load and total loss of power. Truck will be going into the dealer to have multiple things looked at after the holiday season. Only one that really bothers me is the miss under load/total loss of power.
15.6 mpg lifetime, due to long winters and frequent towing.
