I also find this only happens in the first few miles of driving. The last two weeks I have been switching off the traction control when I start out and have not had the tug occur. ?????

2015 Sierra 3500 4x4, single rear, extra cab, long bed. I noticed this a few months ago, it went away, and now it is back. Very similar problem; the truck occasionally and very briefly pulls to the right. The first time it happened I thought a gust of wind had hit me. It is not a jerk, more of a gentle tug, kind of like someone reached over and pulled the wheel a couple of inches to the right and let go. Only lasts half a second. THIS TIME, however, I realize it happens when the truck shifts. Just happens in the higher gears, maybe the top two, maybe the top three. I have not narrowed it down in that regard. So, yes, probably around 40 - 50 mph. To me, that definitely makes it a drive train issue. Has anyone else noticed this?

I don't swing that way, but I could just kiss you right now! I can't tell you how many times I had to jump start my truck because I forgot to unplug my dash cam. Overnight was usually okay, but more than that meant a dead battery. After it happened again yesterday, I was determined to find a way to make the power outlet go cold when the key was off. I actually came in the house to use Google to try to find a switched wire I could tap off of and run to a relay for the power outlet. I had Googled for solutions before but never came across this post. Like some of the others, my manual says nothing about switching the fuse to the other pins, but it worked perfectly. THANK YOU!!!
