Onstar Module Needs Replaced
I just found out my OnStar module is out on my 2022 Chevy blazer. Worked fine. Only thing I’ve had done lately is an oil change and tire rotate. I am wondering if they did some kind of software update, but it doesn’t say anything on my receipt and they didn’t say anything to me about it. I’m under 35,000 miles. My car is not quite three years old. We’ll see what they say about replacing it.
There was a recall for the Telematics (OnStar) Module that was a software update and it had to be performed at the dealership level. It reprogrammed the module so it would shut off after it completed an over the air update as there were instances where it would not power down properly and ended up draining the battery.
My 2023 Sierra had the module fail PRIOR to the update, but it was successfully installed in my 2024 Sierra. I have been without OnStar in my 2023 for almost 6 months with no estimated date for resolution and a lot of run around from GM Customer Care and the dealership.
Hopefully your resolution process goes better than mine.
That is exactly how mine stopped working. I was unable to get the recall update right away due to travel. I had zero issues with my vehicle or my battery. After I got the recall update, onstar was dead and so was all of the features that go along with that. It's been 3 months and my dealership service department do not have a date for the part. After reading all the complains on here, I have lost hope. This is unbelievably ridiculous. They are in no hurry to remedy this problem. My vehicle is still under warranty.
I received a call from the dealership that the module had finally arrived. It was fixed yesterday and everything is working.

Your reply makes me wonder if that is the issue on our 2023 Chevy truck. Something keeps draining the battery and no one can find it. Already replaced the battery, last time it was towed in, they wanted $160 to diagnose again, we didn't want to pay it, since it's been run through the process 5 times now at the dealership! So just buying a jump starter for a year and a half old expensive truck😝
The recall update was supposed to address an issue with the OnStar module draining the battery.
Ironically, I came out to find the battery in my 2023 Sierra dead the other day. When I finally got it jump started, I took it to the local auto parts store to get a reading for any potential diagnostics codes given the "check engine" light was on but no error messages were in the display.
The code reading came up with P262B - Primary DTC: Control Module Power Off Timer Performance. No Verified Fix.
Not sure if this is any help, but I figured I'd share.
