Update
I’ve got a 23 and it’s asking if I’d like to do the update. I’ve read here that several have had issues with the car after or doing one. Am I concerned for no real reason? Sounds like the current one only takes about 5 minutes.

Just do the update at your house where you don’t have to worry about being stranded, if the dead battery/bricking issue you’ve likely heard about is your concern. Your other option is to have your dealer install the update.
I’ve done four updates on my 2022 Stingray and 2023 Tahoe (3 on the Stingray, 1 on the Tahoe) and haven’t had a single issue.

A little risk but only that...
I've done 3 OTAs from inside our garage since 10-21. Followed the instructions on the screen. All have gone according to expectations. Though there have been some negative outcomes for sure. And this has created all manner of rumor and off the wall solutions. But vast majority of OTAs have no issues and accordingly go unreported. I'd man up and git 'ur dun.
Battery condition is paramount for an OTA. The State of Charge must be 70% or greater. A common reason for a failed update is the ambient temperature. When colder i.e. at/under 14F you have less likelihood of a successful OTA. This can be the greater impact of cold weather on the battery performance. Cold combined with the car not being driven for a period of time, a successful update is also problematic.
The download link is similar to that of your phone. If your 'hood has good phone coverage, the OTA server link should be similarly good. I wonder if it is the same server as On Star, but no reason to believe it is.
The update announcement will remain active for 30 ignition cycles from the first attempt. Whether due to a failure or the owner choosing Remind Me Later. After 30, the OTA is abandoned.
If you have a failed update, you can manually retry it. Home>Settings>System>Vehicle Software>Updates. Both pending and installed OTAs will be listed.

Thanks all for the info. We have good coverage here so should be able to do it in my garage with the door open. I try to drive it at least once a week these days. But if I can’t I put it on the tender. So battery shouldn’t be an issue.

And it is a good idea to check the car after about an hour to make sure everything went OK. Otherwise the car could be sitting there just draining the battery.

There are what, at least 60,000 C8s on the road. With the possible exception of 23MY cars, they've probably all gotten at least one update by now. We've only heard of a very few that caused problems. It would seem the vast majority of those updates work fine. I'd just make sure your battery is in a good state of charge.

I've done 2 updates on our '22, and the first completed normally in less than 5 minutes. The second failed, but I got a message indicating the failure a minute or so after hitting the update button. In that case, I started the engine, hit the update button again with the engine running, received a message to shutdown engine, place in PARK, and set the parking brake. After doing so, that update also completed successfully in less than 5 minutes.
I've seen several folks now recommend starting the engine before hitting the update button. The car will instruct you to shut it down before it proceeds.

For what it's worth
My 23 z51 updated last week with no problems (I received it 7/2022)
When I started it up to move it a few feet in the garage- I got the update notice. at shutdown it went fine- then alerted when it was done- took just under 5 minutes
no problems

Sounds like a pretty good track record of successful updates.

I think it is not wise to apply the updates anywhere where you might run the risk of being stranded or having to wait for the update to upload. I always do the updates when I am home.
I am interested in knowing what the common denominator is with those experiencing the car losing battery power or "bricking the car" when updating.

Details
I don't think those who have not experienced any problems with the OTA updates are minimizing the issues those who have been experiencing. I think it is vital for those of us who haven't experienced any issues to share some of the details of how we perform the updates so that those who have had issues can hopefully avoid them.

The last part of my previous post is reference what the common denominator is for those who have experienced the car “bricking” on them during the update process. I think Red Mist Rulz is onto something with the battery needing to be in a good state of charge.

I have a '23, built 12/22, and just got an update message which if downloaded allows for future updates...Initially I selected download, but it came back with a message saying conditions were not adequate to allow download and wouldn't allow downloading of update...So I took my C8 out for a nice 45 min. cruise and when I came back, I got the message again to install update, and this time it allowed for the download of the update...Update only took a few minutes and everything was fine afterwards...
