My 2009 Tahoe z71 has had this message come on and off. seemed to only come on when I hit a bump, when it was above 50 degrees. the interior lights would come on, the doors would cycle through lock and unlock and the chime would sound. now along with that, every now and then when it is parked, the alarm will go off like someone is trying to break in. won't happen when I only lock once from the key fob. dealer replaced the back window latch, didn't help. I replaced the whole hatch lock, didn't help. now, it has done this when I first start it.
