Perhaps look at your update history, then do an online search with whatever update numbers are provided?
My wife purchased a new 2025 Equinox RS AWD that had an OTA update fail, leaving the radio and both dash screens on all the time, even with the engine off and the doors locked.
I took it back to the dealer the next day, fearing the battery would be run-down.
The dealership was aware of the defective OTA update and did a software update to fix it, and applied other software updates. The service advisor was unable (or didn’t care) to tell me what the updates did (other than fix the defective GM OTA update). He could only tell me that the technician did seven software updates.
GM has numerous problems with their vehicle software and keep pushing out OTA and dealer updates in an attempt to fix the defects - and at times, the OTA updates create new defects.
I believe any time an update is done, GM should have to provide a clear explanation of what was done to the vehicle.
