One of the advantages of using GM’s Global-B electrical architecture in the new C8 Corvette has been the ability for the car to handle large amounts of data as various sensors send info back and forth to multiple control modules. Combined with your Corvette’s wireless hotspot, that same system also allows your Corvettes to receive large data software updates over-the-air so that your car can easily stay updated with the latest changes from Detroit.
While some owners might say these over-the-air updates are one of the best things to happen to the Corvette, others who have encountered issues over the years while trying to update their Corvettes might not be so sure. Hopefully, this next update from Chevrolet will resolve those problems.
Chevrolet issued a Technical Service Bulletin for this update back in July, saying that “The BCM software in certain cars may be preventing over-the-air (OTA) updates from progressing past the install step.” This week, users on the forums and Facebook have recently been posted screenshots of the new software update available for their C8 Corvettes, which requires a trip to the dealership. Chevy says in the notice that, “This update will provide software improvements and optimize your vehicle for future over-the-air updates.”
The reason for this dealership visit is that this update specifically targets the OTA Update system. The new update will be flashed to your Corvette, and the software update should help fix those issues where the battery may drain while the update is being installed. If the battery drain is too much, the update won’t be completed and it could lead to other issues on restart of the vehicle. With the update done at the dealership, the service techs will reprogram the BCM software, and GM says the process should take less than an hour.
We call this a fix for future fixes, which is a good thing so make sure you get that dealership appointment set. If you have already taken your C8 Corvette to the dealership for this update, chime in below with your experience.

Which C8’s?
Is this recall for all C8’s? What years, which models? Z06 or stingray?
All.
Taking my ’23 Z51 in this coming Friday.
I was curious; I’ve only received 1 OTA update in almost 2-1/2 years of ownership; this might explain it!
I got an email stating I needed the update. The “new” me, didn’t procrastinate & made an appointment for the next day. The update took a little over an hour. EzPz…
I contacted my dealership to schedule. Sands Chevrolet in Surprise, Az. The service guy, Craig, I talked to said it would take one-half day. Really? Above article says about an hour to complete. I would have to leave the car with them. He was really sketchy on providing a ride home, and after repair pickup. I payed over $88k to Chevrolet for this unit. Is this what I should expect?
I have a ’21 and a ’23 and I got two emails. The emails do not reference any particular car.
No such notice for 2021.
Not a word about the necessity thereof. It’s one thing if a misplaced decimal point causes premature transmission wear or something like that. But OTA updates like these seem more like ways they can backdoor brick your paid-for product when/if they deem it necessary.
Personally, I would rather force updates only in person and only via direct hard-wire connection. I don’t think we’re too far away from the day when a savvy, nefarious actor can “spoof” the legitimacy of an update and force your car into patching with malware; all wirelessly.
I have a 2021 and haven’t received an OTA since mid 2022. Yet when I took my car in for the 3 year DCT fluid change, there was an update that the dealer applied, but that I was never notified of. GM really screwed the pooch on their OTA software. It’s always been buggy and inconsistent, and still is.
Feel bad for Patrick. This is why I will be going out of state, probably to Texas to buy my Corvette. The Chevy dealers in Arizona suck and ripoff their customers.
i spent 4 hours at a dealer for the software update. The update failed several times and they told me to reschedule. Terrible. Going to try another dealership.
