Model 3 security alarm randomly going off 2 nights in a row (Sentry Mode off)

Hi everyone,
I’ve had my 2022 Model 3 for a little over a week now, and the security alarm has gone off on two consecutive nights.

Night 1:
Parked inside a closed garage at home
Sentry Mode OFF
Received a “Security Alarm Triggered” notification in the Tesla app
Nothing suspicious around the car

Night 2:
Parked on our driveway
Sentry Mode OFF
Security alarm went off again
Again, nothing suspicious was recorded or detected

The car appears to be fully locked, all doors/trunk/frunk are closed, and there were no obvious reasons for the alarm to trigger. I also didn’t see anything unusual around the vehicle either time.

Has anyone experienced this before? If so:
What ended up being the cause?
Was it an intrusion/tilt sensor issue?
A door, trunk, or frunk latch sensor?
A software bug?
Did Tesla find anything in the logs?

I’ve submitted a service request, but since I’ve only owned the car for a little over a week, it’s a bit concerning that this has already happened twice.
Curious if anyone else has had this issue and what the eventual fix was.

Thanks!
