23 Suburban arming alarm with 2nd fob/people inside after 1 fob exits

[navyseal334]

My 23 Suburban has started locking the car and arming the vehicle after one of our fib exits the vehicle, despite there still being a fob/people inside. It has resulted in advertently triggering the alarm when we open the doors.

I don't think we have changed any settings and it just started doing it yesterday.

Then the car would not unlock for me tonight using the outside handle lock buttons, with the headlights flashing 4 times when I tried. If I unlocked with the fob button, they would unlock.

Anyone else run i to similar issues that can help me figure out what's going on? I hadn't connected to wifi in a while until 2 days ago but it said there wasn't any update....

We found that a setting had been changed disabling the outside door locks so that is resolved.

Still unsure why the car has started locking when people/the other fob are still inside after one fob exits.

Do you have “Passive Locking” enabled in the Vehicle settings?
