Alarm went off for no reason at 3 AM

[Jtt777]

So last night had a bit of a panic as my Model 3 alarm started blaring at 3 AM. There was no reason I could see for the alarm and I didn't even get a message on my phone saying the alarm had been triggered.

The weird thing is that as soon as I launched the app on my phone and it "woke" the car, the alarm turned itself off. It doesn't seem to have repeated since.

Really weird.... Anyone else?

It had a bad dream.

Haha I guess so!

But this seriously happened. Bugs in the software code? Anyone else have this on a model 3? I saw someone say this happened on a Model S but couldn’t find someone having the issue on a Model 3.

Contact Tesla, there should be a log entry for what sensor set the alarm off.

You could have a faulty sensor or the alarm could have gone off for a legitimate reason, just not one apparent to you.

I imagine even the Model 3 itself gets spooked by the noises it makes at night.

I just got my Model 3 on the 21st, no issues until tonight. We've had some heavy rain today and at 01:20 a.m my alarm started going off randomly with no message from the app, at first I thought the dog may have set it off but literally ten minutes later, with nothing around, it started going off again. I manually turned off the alarm. Hopefully this isn't anything serious, could the sensors be sensitive enough that water trickling down the car set it off?

if it makes you feel any better. this problem only happened to me once so far and never again... maybe it was just a fluke

What software version were you on when this happened?

 

[Napboy]

This car has an alarm?

That doesn't mean it goes off if the rear quarter panel glass is broken....

I've been having random alarm activations with my Model 3. This usually occurs in bright sunlight or setting sun. I have a feeling the shifting light might be setting off the internal sensor.
Interestingly last night was the first time the app on my phone picked up the alarm.

My Sentry Mode starts recording "events" when it starts raining out. My car has recorded hours of rain...

But rain never set my alarm off to my knowledge.

My alarm's only gone off once - again, to my knowledge - and it was at the same time I heard a really loud bang outside on the 4th of July. I'm assuming it was a firework, but it sure didn't sound like one. It sounded like the noise the garbage truck makes when it picks up a giant dumpster and then slams it back down, just louder. My phone sent me a couple push notifications when that happened. I went outside but didn't notice anything wrong with my car. I forget if Sentry Mode recorded anything or not. The alarm was already off by the time I went outside, so I'm not sure how long it was on or how exactly it turned off.

About a month ago, my sentry mode alarm also went off at around 6am. Thing is, my car was in my driveway.

I have a Outdoor Nest Cam pointed at it so I checked and there was nothing that could've triggered it. No sound, no motion, no wind, nothing. Weird. I guess it just had a bad dream and woke up screaming?

I wonder... If an insect/bug/spider is crawling over the side repeater cameras at night, would that trigger the sentry mode and alarm?

They crawl on my home security cameras and trigger it's motion recording all night sometimes.

I think the “Jersey Devil” is messing with you!

Was sentry mode on when the alarm went off? If the car has sentry mode on and loses connection to the USB storage, it will trigger the alarm.

I've had my alarm go off due to loud cars that drive by my car.

Mine went off last night at 3Am, but the app or car display showed nothing. Not even a reboot stopped it. Eventually stopped when I open and closed a door
