To me it's BS that my 2008 I traded in with 203,000 miles on it drivability wise drives better than my 2016. I didn't have these problems. Had I known what I was going to run into with how my new truck is. I wouldn't have bought it. I would have kept my old truck or looked at something else from another company
I have a 2016 and it has done that since the 3rd day I owned it to current. That's been since 7-1-2016 and it doesn't get better with more miles. I have 24,500 and it still does it and I have piles of paperwork from the dealer and I keep being told it's normal. This is my first vehicle I've bought new and it's a nightmare so far. I have 30 years in the automotive field as a tech. To me it's not normal along with the hitching under a load grade or no grade. It hitches like you have plug wires off. Another issue that I'm told has to done at GMs level do to it being in the programming. Have had open reports with GM and I was told they were working on it. Hope they come up with something fast for the transmission issue. I'm going to one and done if not.
