I agree DEF got easier since they started putting it at stations, but we still didn't have it at the stations in our area. The GM gauge on the instrument panel is terrible, coupled with he numerous sensor issues made it problematic for us. When you have a sensor go bad, it would pop up on your dash display saying maintenance require, covering up the entire instrument panel. When it takes two weeks to get your truck in for an appointment, that sucks. You can drive it for a while in that state, but each time you get in the truck to go somewhere you get this ominous mileage countdown and from what we were told at our dealer, you don't want to run the truck to the minimum because you will introduce new problems.
