Random beeps when idling???

[Sincerelytaty]

I have a 2020 Buick Encore GX and when I’m idling in the car, the horn (or car) will randomly chirp 1 time. As of yesterday it did it 3 times rapidly and then once I got back into the car an hour later it immediately chirped about 3-5 times. I have no clue what’s going on. There are no dash lights indicating anything is wrong.

My '24 did the same thing yesterday. I kept it idling while she was in a short doctor's appt. and all of a sudden it beeped (horn honk) and then shut off. I did see "Key Not In Vehicle" on the info screen and due to heavy clothing, I guess it lost signal with the Fob. I pulled it out of my pocket, restarted and no issues. When we got home I managed to leave the Fob in the console and it sounded the horn 3 times when I closed the door to signal that I'd forgotten the Fob. It's honked twice for 3 times each in the garage since. I assume the battery is low???
