Purchase two brand new Denali trucks with the 10-speed transmission diesel motors and having a problem with hard shifting come especially as ID accelerate to a stop and the truck lunges forward and if I'm not careful feel like I could hit somebody in a crosswalk. I know some of these trucks take time to learn owner's shifting habits but seems to be a little extreme and worried about taking it into the dealer to be told that the off-road fuel might have done this do to my other vehicle losing warranty because the dealership said I had off-road fuel in the truck which I've been told by the EPA doesn't even exist anymore since 2012 I know it's a little bit of a sarcastic comment but has anybody had problems with lunging
