GM has started a service update to address a problem with certain 2022 Corvette Stingray units that may cause the vehicle to display a low charge status warning, despite the battery being full.
The problem: affected 2022 Corvette Stingray models have a condition that may cause an underestimation of the 12-volt battery state of charge.
The hazards: If this occurs when the battery is sufficiently charged, the alternator may not enter fuel saving mode, negatively impacting fuel economy.
The fix: an over-the-air update will be pushed to vehicles to remedy this problem. An over-the-air update is an internet-enabled update that can be sent to vehicles wirelessly without the need to visit a dealership. Owners who still wish to take their vehicle in for service can also have the body control module (BCM) reprogrammed by a GM technician. This software update will be performed at no cost to the vehicle owner.
Affected components: body control module (BCM).
Affected vehicles:
- 2022 Corvette Stingray
Number of affected vehicles: it’s unclear how many vehicles will need an OTA update or BCM software update to address this problem.
Owners should: involved vehicles will receive an over-the-air update via the infotainment system. Owners with further questions or concerns can reach out to Chevrolet directly using the contact information included below.

- GM service update number: N212351870
- Chevrolet Customer Service: 1-800-222-1020
GM also issued a small recall for certain 2022 and 2021 Corvette models earlier this year due to missing halfshaft bearings, however this recall only impacted 22 vehicles across both model years. A full list of manufacturer communications regarding the 2022 model-year Corvette, including service bulletins and updates, can be accessed via the National Traffic Highway Safety Administration’s website.

I would love to have that problem, it would mean I have mine , but I am still waiting after 30 months!
So the electrical system has to guess about the state of charge? Are you kidding me? It should and MUST! know the actual state of the battery at all times. It’s indescribably, galactically unacceptable to write such poor software code. Get your act together GM. You think way too much of this sorry example of a car.
At least it’s not a recall like Ferrari has going on with all cars since 2015 that ignite without any warning!
I would suggest that GM also look at the 2021 models as well.
From the date mine was manufactured on 4-23-21, BEFORE I even picked it up at he NCM on 7-2-22, I was already getting OnStar alerts that the battery was not properly charging. And continued to get them in my monthly OnStar summary for the next 6 months.
The dealer would check the charging system and say everything was fine. Repeatedly. OnStar would state that the car was in fact alerting a battery/charging issue. So just finger pointing. In fact the dealer started to get irritated that I would keep bringing it in to be re-checked when I would get the OnStar monthly summary alert which clearly stated to do just that.
After 6 months it suddenly stopped with no explanation. So I am not sure if GM resolved it or if OnStar just stopped tracking / reporting it, after my constant complaining that all the “false” alarms meant I would never REALLY know the true battery status.
And now we see here that it is an actual problem that does impact vehicle performance!!
that is easy to find out. Just get your self a battery with a low state of charge, or drain your existing battery to a low level and see if on star reports it. I would say the dealer contacted on star and had them remove the low battery warning from your reports, since it was bogus and a nuisance to the dealer. So, yes… in my opinion, if you ever do have a battery issue, on star will not tell you. Performing the above test will prove it.
Makes sense…except for the “that is easy…” part. 🙂
I guess Mr Scarfi is perfect. Chevrolet built a beautiful but complicated vehicle. Small issues may arise from time to time and as long as they are addressed I would be happy.
I had a low battery issue last year, but charged it with my Ford 🙂 and then got the battery tender for Christmas. Did have an issue with a low battery when doing one of the OTA updates. The My Chevy App did tell me i had a battery issue when I had one. But so far all is well. Driving the Vette more these days.
I’ve have that same issue now and then with my 2016 Zo6. Not a damn thing wrong with alt or battery. My bug must have migrated to some of the C8’s (LOL). I think the ECM is lying to my PC. Though hard to do, If the battery is less than two years old,forget about it. Enjoy your C8
Well, funny thing. When I sold my 2014 Z51 C7 in 2021 it still had the original Delco battery
I did not drive it regularly (only had 8000k+ miles) and never had a starting issue.
My ’69 BB is only driven on nice weekends, LOL. and I just replaced my 9 year old Interstate battery
and only because of the age.!!!!!!
Yet my C8 decided to kill the battery just for sitting for 2-3 weeks. WTH I guess they dont make them like they used to.
My 2022 C8 lost the battery just after 1 week in my worm garage. The car is only 3 month Old at the time.
Now it just stands there and I cant start it.
No dealer in denmark. What can I do?
Have tried with new battery. 🥺😩
