Random Alarm Sounding

[Bootneckshuffl]

Hi all

Strange occurrence last night

Around 11pm, alarm went off for no apparent reason. Examined the CCTV this morning and nothing anywhere near the car, no wind or rain or anything either to possibly trigger. Mrs got a notification on her phone, I didn’t for some reason.

Anyone had any phantom alarms recently?

A fly inside the car has been known to set it off

I had a problem once when parked near plants that were waving in the wind.
I'm not fully sure if constant movement near the car will set the alarm off but I couldn't disable it in any way, it kept sounding all day yet never had the problem since.
Does movement near the cameras set the alarm off?

I’ve had a good look about in there this morning. No fly to be found.

Spiders too.

This happened to me so much. The tiniest fly. So annoying

Maybe in future they can combine ultrasonic detection with a secondary sensor and/or camera confirmation?

Spiders, fly’s, dust and sometimes even bacteria crawling over a sensor have set mine off.

Very strange alarm event occurred a couple of days ago - Parked on the drive, alarm notification on the app & when I checked less than a minute later the car was still locked, no alarm sounding but the passenger seat had moved forward & down into a fully reclined 'come and lay on me' position.

This car has always been a flighty little madam so I'm half expecting the rear lights coming on in darkness whenever a gentleman walks nearby

Hopefully that's a software bug and Tesla may soon introduce passenger seat profiles?
The movement of the seat whilst the car is locked no doubt triggered the motion sensor.

Or maybe I'm just an eternal optimist

Maybe just a very big spider pressing the button. If that was me I’d get some exterminators out just in case.

I've got a 2020 ME and never had an alarm trigger until today - two occurrences...
First, car parked not near anything else, I approached with the phone key and at about 30 feet away, alarm set off. I thought was that sad dance the thing can do, lights flashing and honking away.
Second, car parked on my drive (set so sentry mode is not activated there) and alarm goes off again. No-one near and the app tells me that sentry mode has activated the alarm.... How??
Nothing else for the last few hours apart from some very strange rumbling noise when reversing with nearly full lock on. Car's falling apart....

No more significant flies, etc in the car today than in the last nearly 2 years, over which not a peep from the alarm.

What's a significant fly

Raise a service request with Tesla and they can tell you what sensor was triggered -e.g. interior.
