  1. Any rubbing with the factory splash guards and the 275/60r20's? Sent from my iPhone using Tapatalk
  2. Just got my 2015 Sierra with 3500 miles back from the dealer with the same issues as the OP described. They did confirm the smell and proceeded with the normal checks of the fuel system, all of which tested ok. According to my receipt, they contacted the GM tech line and was told to replace the following parts: p/n #12626354 gasket (qty 8) #12618337 pipe #12618336 pipe It's been a couple weeks and so far so good.

  3. If you press power, home and menu at the same time it will open a dev screen. From there scroll down to the HMI tab and press menu. You will find current hardware versions there. Sent from my iPhone using Tapatalk
