Dropped mine at the dealer today and the service team seemed pretty much clueless about what I was talking about regarding enabling Extract Mode. There was a service issue from GM for sensors that the guy found in the computer. Got a call a few hours later that they had to order new sensors and it will be a couple days to get them. So my takeaway is the dealers who have received early trucks did NOT get the sensors shipped to them by July 1 and all of this communication from Corp GM to dealer service depts is severely lacking. I guess lucky for me the dealer is only 15 min away not longer like Malaligned. Guess I wont get to use the new mode this coming weekend on our camping trip.
