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.

Same exact issue with my 2021

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.

Yes, Let’s hope so! Sounds like early Dec we’ll have the update from GM Engineering

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.

    • Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra. 
    • I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

    • What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.
    • People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.
