Yes, true i guess….will not know for sure till several attempts at using it i supposeSounds like it was not an everyday issue, poster said only happened twice.
Not "testing" it. I have too much on my plate right now to risk not having my vehicle available. It does stink that it's getting so cold and can't use starter. The woman at the dealership said she probably wouldn't use it either. Not that this week get me anywhere, but I will be writing to GM and possible the Better Business Bureau. I'm at an age where I don't settle for junk anymore.Yes, true i guess….will not know for sure till several attempts at using it i suppose
Make your own call...but, when I actually read the bulletin from March, it is pretty clear GM understood the issue as being part of the Body Control Module communication w/ other modules on the vehicle ("BCM Messaging Issue"), and is pretty confident that the software update to the BCM resolved it.Not "testing" it.

Yeah, I realize that. Definitely not stupid, but crazy to have to do on a vehicle that costs so much.Not having a vehicle? You do realize by simply unhooking a battery terminal for a brief moment and reconnecting all is good after that…or dont you?
Im not insinuating that this is “okay” to have to do to a brand new vehicle, but it is certainly worth doing to be able to use your vehicle again.
My bet is you won’t see the issue again now that you got the BCM updated.Yeah, I realize that. Definitely not stupid, but crazy to have to do on a vehicle that costs so much.
I hope not. This is the second time is been updated though.My bet is you won’t see the issue again now that you got the BCM updated.
If you read all 19 pages of this thread, you will find some posters who got the update, and have reported not seeing the issue again. You will also notice there are no members posting with vehicle deliveries later in the year mentioning this problem. GM likely put the updated BCM software in the production line, and thus prevented this issue in the field for later builds.
I’ve not heard whether this issue affects the Silverados or not. Suggest searching the MFGR communications on the NHTSA website; or ask your dealer. You will be getting new BCM software anyway; as the DRL recall does apply to the Silverado.I came across this thread. I have a 2022 Silverado ZR2 that just experienced the exact same issue today. It was delivered to the dealership mid-October.
Keep me updated on yours!!! Mine got towed on Wednesday. Same thing. Got in to try to start it, every light inside came on, heater was running, it was throwing all sorts of errors on the screen and telling me to hit the button again to start. Radio worked and everything, but it would not let me shut anything off and would not actually turn over the engine or start it! I could not disconnect the battery because I did not have the tools. I could not shift it to neutral manually or by pushing neutral, so I had to call a flatbed to come tow it to the dealer. It's a 2021 Tahoe Z71 4x4. I do not know if my vehicle received an update or not one was trying to download for about a week but kept saying it failed to download so who knows. The dealership has NO CLUE what is going on with it. I have tried to tell them stuff on this thread to check but they keep doing their own thing. They have hardly even looked at it. I am so beyond frustrated.My 2022 refresh did this right before Christmas.. I used the fob and got in it and hit the button and the truck shut off, lights were on and heater was running but dash lights were dim,it wouldn’t start and kept saying start again well it wouldn’t let me manually turn anything off so I jumped in my wife’s Subaru and drove to the airport and returned 2.5 hours later with the lights still on and heater running.. so I tried to start it then and it said low battery so I disconnected the battery and tried it a minute later and it started up with no issues, chevys going to look at it on Jan 5th and my truck was built at the beginning of July so..
Just go buy a wrench, disconnect your battery, reconnect it and be on your marry way. Then go find a different dealer.Keep me updated on yours!!! Mine got towed on Wednesday. Same thing.

Add me to the list of people who owe you a 6 pack. ‘23 SLT with 4000 miles. Actually found this thread from googling! So good SEO for our site admins.so.... a potential home fix then should be to disconnect & reconnect the battery ground cable, that would essentially "clear" the computer for the most part.
maybe the next time this happens or pops up on the thread someone can give it a try.
keep that in your suggestion box for now until we discover otherwise.
Edit***reportedly doing this has worked for 1 person so far
They tried that. Also tried to force update. Still not working.Just go buy a wrench, disconnect your battery, reconnect it and be on your marry way. Then go find a different dealer.
There is a fix. It involves a software update to the BCM. See this post.Hi All Thanks for the Posts! I Purchased a Brandy New 2023 Tahoe a week before Christmas and was Loving it unti Christmas morning. This is like a fairy tale but its not I loaded the car with gifts and food hit the remote start and loaded all 3 rows with family guests who flew in the night before for a early trip to Grandmas house. When on the coldest day of the year if anyone remembers hear in northeast it was teens to single digits, I hit the break and start button the truck became possessed. Like most I tried everything to get the electronics to shut off as the engine stalled to no avail. I even tried open closing doors and locking and unlocking to trick the computer. Nothing worked so i grabbed a 10 mm socket and disconnected the battery for about a minute while we were all freezing. Computer reset and I manually restarted the vehicle and off to grandmas house. Fast forward few days after New Years i called the dealership to hear a response “we never heard of anything like that before, keep an eye on it and let us know if it happens again”…..So as of January 2023 I guess theres no software fix for this issue…Pretty sad!
