My 2017 (when the switch is on 2 wheel drive) when I am leaving my driveway going slow and turning I can feel the other tires pulling as if the 4 wheel drive is engaged. It also makes a whining noise. This happened 3 times one day. I turned the truck off and restarted it then it went away, but did it again the next day. It is now sitting at the dealership and they cannot get it to replicate my issue. Anyone have an idea of what it is?
