2013 E92 M3 Alarm Problem

A coworker of mine told me that several times today my car's parking lights, AE's, and tail lights were flashing like an alarm was going off but no audible alarm sound. I wasn't able to observe it myself but when I unlocked the car there was no iDrive warning of an alarm activation.

I did some minor troubleshooting - the siren works with the panic button, the alarm chirps when armed and disarmed, and when I open the hood and hold the hood switch in it arms and disarms normally. When I try to lock/unlock the car without depressing the hood switch it just locks and unlocks with no chirp. The only interesting thing is if I arm it by manually holding the hood switch in, THEN release the hood switch it doesn't go off at all.

My only thoughts are a) a malfunctioning motion sensor/tilt switch (I work at a VERY noisy airport, but have owned the car for a year and this never happened), or b) some sort of heat-related problem as it's been 95+ all day without a cloud in the sky.

Anything else it could be or anything else I can check? It's due for service in ~1600 miles so would rather hold off on a dealer visit for now - closest one is 1 hour away. Thanks!
