Well mine worked at first as long as it was connected to a wifi other than my truck.  I called onstar and an over the air update was performed and all started working like it's supposed to, as far as I know.

OK, fix totally worked.  But..... When they took my truck in to do the fix the tech tagged a wall and trashed my rear passenger fender around the wheel.  I was just under 1500 miles at the time.   I am asking them to fully replace the fender with a new fender, not repair, no bondo.   Am I thinking right on this.

Totally agree and I'd want that done too, but I don't think they'll do it unless you know the GM at that stealership.

Got a call from the dealer, they are getting a complete new fender.  I got my sales person to be my eyes and ears on that.  I think the fact that I bought from him and still have a van with 296K miles on it motivated him ?

EXACT same issue with my 2021 Trailboss I bought 4 weeks ago.  After 3 weeks in the shop, They tell me that GM is still having an issue with the truck WIFI connecting to any IOS products, like hotspot for example

Glad you found this.  My 2021 AT4 has the exact problem that's been driving me nuts for the last week that I've owned it.  Being on OnStar a couple of times and they have had no answer for me.  It's not that big of a deal cuz I'm using Android Auto but Will keep my eye on this now that you've listed it.

I too am using Android Auto. I also have an unlimited data plan for WiFi and the complete OnStar package. At times my Wifi will completely quit and I have to contact OnStar to get them to send a code to the truck. Also, from time when I use the wheel mounted volume buttons my instrument cluster screen will display the volume level but not on the radio screen. But when I use the knob on the stereo, the screen radio shows the volume but not on the instrument screen??? I have also had issues with my settings I chose going haywire. I hope GM gets all these issues fixed before my warranty runs out or I sell it!!

I've had my truck for roughly 10 days and found this issue early on. I will have it resolved when they replace my passenger side mirror since it was damaged prior to delivery.

Glad I found this.  2021 LTZ goes in Tuesday.  I'll have to convince them that it needs it.

I am not sure if my problem is with this issue. I set the SOUNDS to what I like (12 Bass and 6 Treble) . After shutting off my 2021 Sierra SLE and then restart it, all of the SOUNDS return to a neutral position. I did contact the dealer but he stated he did not know how to fix it and there were no bulletins. I then contacted GMC  in Detroit and they said they are checking into this. Has anyone else had this problem?

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
