Your problem is likely from one of three possible causes 1st one is loose ground somewhere possibly ecm on harness for ecm in gm vehicales that is a common issue my 03 avalanche started off doing just as you described while driving the doors would lock and unlock on their own later it got worse and it locks would cycle and a/c temporarily stop and engine would bog eventually lead to the ground breaking altogether resulting in engine cutting off and not cranking and security light staying on the other possible causes of you suv doing that is ignition switch and or bcm
