2023 C8 of the Year Finalist - Unmodified
I'm fairly certain that OTA updates were discontinued late last Sept due to chronic problems with hangups and failures draining batteries and resulting in some C8s having to be towed to Dealerships to resolve system problems created by some of these OTA updates...
The last update that caused problems for many was GM N23-2418150 (9/26/2023)....
I'd be interested to hear if anyone has received an update after Sept '23?

GM N23-2418150 failed on my C8 (first and only failure). My last successful update was GM N23-2407890 on 09/25/2023

I missed that GM had permanently suspended OTA's. I did them all (4) without issue. But felt the same anxiety when I started each one. And elation, when I revisited the garage to find the OTA process had come and gone.

2. Once the download has been completed there are certain conditions that must be met for the upgrade (Install) to happen including checking the batter state so Charge (SOC) based on ambient temp etc.
3. For the upgrade to happen the car must be parked so don't worry about driving. If the upgrade started and you start the car. the upgrade is backed out.
4. Most upgrades take about 15 minutes. My C8 takes about 5 minutes. But you can just park, accept the upgrade and leave the car.
5. You should not need a tender unless your battery is failing.
GDB069's experience with OTA updates mimics mine. For my '22 Z51 HTC I have received notification of 4 or 5 updates. Followed the simple instructions while home or away and the update took about 5 minutes. No issues and I am happy and confident with the process.
