Recently took the Blazer in for a series of small annoying issues, and based on information from this forum was adamant they look at Vehicle Wide Programming.
Technicians were able to find Bulletin #24-NA-143 that did need to be performed.
Some of the issues resolved:
-Regen randomly shutting off
-Volume randomly starting at full blast
-Charging error messages and problems activating fast charge sessions
-GPS randomly quit working or wrong location
-Two separate buttons for heated seats and ventilated seats
-Error Code 302

If you are seeing any of these issues then you likely need this update.
Make sure to give this bulletin number to the dealership

Oh, sorry. I am not trying to backseat moderate. The post is useful. Not everyone has gone through each and every software relates thread to find this info.

I was being sarcastic when I said I’d delete.
It is apparent that the VAST MAJORITY of all issues with the Blazer relate to these updates. Most posts ask the same question and raise the same concerns over and over.
We need to ensure there is clear communication on this, and it doesn’t get buried in the forum.

Worth noting since we did the vehicle wide programming the charge curve no longer has thermal crashes. Also we now have free data plan while in US (from Canada) that we didn’t have before.
