Guys I have the same problem and at wits end trying to deal with it, upon going through all the system I found something that actually works try this. Go to settings then to System then to Quick Start up and turn off this feature, now your system will reboot every time you get in and start it up, so far it has worked every time
I just bought a 2024 GMC Sierra 1500 Elevation and only had it a little over two weeks and the infotainment system would freeze up every morning, I learned how to factory reset it because nothing worked except the steering wheel controls. This has been happening since, I finally was able to get the service department to get it in, now I have to leave it with them for a week to run teat and see, I’m discussed with this especially after spending all this money on it.
