2021 Sierra with IOT, same exact issues, same convos with Onstar, same outcome. The technical info I am seeing is that GM is aware and is working on a calibration update. They did not specify OTA or dealer service required as of yet. Crossing my fingers for us all on a fix soon.

Same thing to the "t", here also. Have a case number on truck. This was Friday the 27th. So nothing has been cured yet guys.

I am thinking about asking for an extension of my onstar free trial as I have not been able to use a lot of the functions due to the bug.

I have the same issues as everyone above. Brand new 2021 LTZ. Onstar help was a joke. Dealer did tell me a fix was coming in Early December.

Yes, my 2021 AT4 is having the same issue. I’ve been on the phone with OnStar for hours and the new service bulletin as of today at least assures me a fix is coming. Frustrating though for a two weeks old truck. At least my wifi, OnStar, and Apple CarPlay are working. I just can’t download any of the apps and don’t have the marketplace icon either. I get the message found in the attached screenshot when I press the APPS icon. And I have the unlimited data plan, so it’s not a data issue. Anyway, hope GM gets a fix out by December.

It's been a month now and my truck has not been able to connect to the internet or access apps...  Thinking this was just my truck, even though technical assistance said there were others.  Well I just ran across a bulletin for this issue(s).  Of course there is no fix yet, but engineers are working on a solution.

It’s off GMs website.  I work at a dealership so I have access. Not sure if any other website would have it listed.

Anyone here any updates on this, early December is about gone?

 

Yes, I was told by my dealer, this week. The week of the 13th the update should be at our dealers. Sounds like it won’t be an over the air update, we’ll have to swing in to the service dept to have them update it. Shouldn’t take too long.

    • One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...
    • 'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine. 
    • New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.
    • I am not a NOCO fan for a charger I would leave on a battery 24/7. The reason is, it doesn't really float. It waits until the battery drops to a certain voltage and then charges it back up to 14V. It's better than no charger I guess.
    • I would never do anything but lithium.   If the vehicle is stored, just turn the disconnect off. My batteries are completely disconnected form everything in the trailer when my disconnect is off. Trailers don't always come that way as some still keep the CO/LPG monitor on. When mine is off...it is off.   As far as storage temps, LiFePO4 are good down to -20°C. I would store them in a heated place if it goes below that. You can also get heating mats with a thermostat if power is available.   The way the heaters work, if it's below 0°C, if a charge comes in, it is directed entirely to the heater until the battery gets above 0°C and then it allows the charge to go to the battery.   For my Android tablet I use as a display, I can move it inside my house if I was ever in an area that got super cold.
