I came back from lunch today (in someone else's vehicle) and noticed my Cayman's lights flashing in the parking lot. Similar to when you turn on your hazard lights. No noise, just the flashing. I have never seen that happen before. I went to my office and grabbed the keys, but when I returned just a few minutes later, the lights were no longer flashing. I checked my dashcam and it did not show any incidents during lunch. Anyone have an idea as to why that might happen?

Any ground movement, tremors in Salt Lake City?

991 - Hazard Lights constanly flashing - Hello, My 991.1 (2012.5) has been experiencing a weird issue recently. After I drive the car and lock it, the hazards will flash. This used to occur randomly and would stop when I unlocked and relocked the car. Now, it's doing it constantly when parked...

When the alarm goes off, doesn't the noise stop after a while (because of annoyance factor) but the hazards keep flashing for a while longer but not indefinitely.
