  1. I suspect that you may have turned off stability control and not traction control. Two separate systems.
  2. As soon as you get to non-slippery pavement like a parking garage you need to get it out of 4WD High. You can move it to Auto or 2WD. That "whine" you hear is undesireable wear and tear on your front diff and/or transfer case. I don't have the manual in front of me to check on what it takes to move from 4WD H to Auto, but I suspect you can do it at least 15 mph or less.
  3. I think you can use carnau's post to see if your system is working correctly. Auto does take away control and might not operate the way you want but I haven't had any issues. My point? Your system on Auto may or may not be working properly. The only thing I disagree with in that post is that the truck does get to the desired temp as fast as I want it. Here in Phoenix, when it's 110 out it blows cold air at full speed for quite a while to cool down the truck before it slows down. It doesn't get too cold here, but on the past few mornings it's been blowing hard to heat up the truck w
  4. I guess I'm still concerned about harmful levels of dirt getting into the engine and oil over that amount of time. That's one of the main reasons I would not go that long. I don't know if my reasons are well founded, but I do have comfort changing the oil every 5000-6000, or when the oil life monitor says to, whichever is shorter.
  5. Looking at that history of frequent tuneups, tire checks and transmission checks over just a few thousand miles, I would guess that they owner turned it in for shaking or something similar. Walk away.
  6. I'm in this camp, I never notice nor feel any discomfort like lack of responsiveness. Sent from my SM-N950U using Tapatalk
  7. Well, without walking out to my truck to check, I could guess that it's additional airflow for the front diff. GM added a hole in revised skid plates for my Hummer H3 for this purpose.
  8. Glad you got it working. Note that Android Auto is finicky about cables and cheaper cables might not work, nor charging only cables (vs. cables that charge and transmit data). I switched to Anker Powerline+ and that helped my initial Android Auto issues of intermittent connections.
  9. Loctite and look up the torque specs to ensure you are tightening it to spec.
  10. Just got a firmware update on the radio for a similar issue, even though my truck is only a few months old. Service bulletin #17-NA-025 and while that bulletin doesn't list this issue (from what I've read) it seems to be working so far. BTW, it didn't matter which USB port I used and it also was not recognizing a flash drive. This was an intermittent issue for me.
  11. TPMS has to be relearned after each tire rotation. The tire shop can do this for you, you can pick up a tool on Amazon, and/or follow the procedure in the Owner's Manual. The TPMS are set to each specific corner upon each relearn and they do not automatically relearn if you rotate the tires.
  12. I've been looking for a manageable way to get my playlists and songs from iTunes to a flash drive to play in Mylink (2017 LTZ). I've seen a few solutions out there that mostly revolve around editing the playlists files, but those are not practical for me as I can't copy over my entire music file to a flash drive. My solution involves an Android phone or tablet (sorry iPhone users). Items needed: Android phone or tablet Synctunes app from Play Store (paid version) PC Flash drive Synctunes is an app I found to get my iTunes songs and pla
  13. Found a TSB which has replacing USB hub as a possible solution. Date ReportedAUGUST 02, 2016 NHTSA Reference#10082422 TSB Reference#16NA242 Description: THIS TECHNICAL BULLETIN PROVIDES DIAGNOSTIC TIPS TO HELP CORRECT MULTIPLE CONCERNS REGARDING THE USB PORT BEING INOPERATIVE OR UNABLE TO PLAY MUSIC THROUGH THE USB PORT.
