2024 GMC Sierra 2500 HD with Duramax.
I tried to install the subject update on the display, I hit "install" and followed directions to turn the vehicle off. This morning the battery was dead. I jumped the truck and got it started.
The "My GMC" app is telling me the software is still installing and when I try to start the truck, the engine starts, but the displays are blank, after 30 seconds the displays light up and the engine turns off, but the displays all act the engine is running. This will reoccur if the engine is restarted immediately. After it sits for >10 minutes I can start the truck normally, but it says I have an emission systems issue, the check engine light is on and the traction control is turned off.
Any idea's on how to restart the software installation?
