Alarm goes off between 1pm & 3 pm daily!

I know my 2015 Denali probably isn’t haunted but this is crazy right? It’s really annoying too!
My best guess is something happened when I temporarily took out the battery to charge due to not driving much because of COVID. Could this have caused some kind of glitch in the system? It didn’t do that ever before and it didn’t do it after battery replacement 2 years ago.
Anyone familiar with this? Thanks

Just the thief trying to get you to disarm alarm! Film it.

Might also get the battery load tested. You may have a bad cell. Also check your cables really well.

Buy a scanner or get it scanned at dealership. I was having issues and it ended up being the hood latch sensor. It was sitting too low and triggering the Alarm. It could be so many things though. Wild goose chase without a scan.
