I have the same problem with my 2016 CC short box.
Last time I took it to the dealer they drove it and of course they couldn't find anything wrong.
Gm rep some help.
2016 Sierra CC Texas Edition with a denali grille
22 inch Gima Paradox
305/45/22 yokohama tires
2 inch Mcgaughys lowering shackles
Airraid modular intake tube
Met Powr-flo Mass air flow sensor
My 2014 Sierra has the same problem it came with the 20 inch wheels. One of the tire was bad the dealer replaced it to no avail.
I decided to buy a different combination of wheels and tires 22INCH no change..
Now since I went to the 22 inch GM will not honor the warranty since I changed the wheels
Thanks GMC
You know there is a problem and refuse to admit it
Had my 2014 Texas edition sierra 1week same issue.
Dealer found that during the vulcanization of one of the tires was not manufactured correctly. The tire was defective.
Try that
