Sensitive Alarm System

There are a number of posts around "random" alarm going off, but I definitely have a pattern that indicates mine is too sensitive.

I have found the following can trigger the alarm:

- sunroof open or tilted
- windows open slightly
- car within two spaces closing there doors or trunk
- my lawnmover (it sounds like a jet engine) going by the car in the garage with doors down.
- another high performance car starting there engine or reving next to me.

Interesting, as long as the key fob is in range, it will not happen.

It is now standard operating protocol that I deactivate the interior sensors to avoid the alarm from going off when I walk away. (three clicks within 5 seconds of locking doors to deactivate interior sensors).

Anyone else experiencing similar sensitivities with alarm?

One more for my next preventive service.

Thanks ...

Only the sunroof being open.
Which is annoying when I just want to pop into a store and don't want to close everything up.
It's the security procedure for the car to sound alarm when you leave the sunroof open. Dealership has a way to deactivate it if you need it.

If I deactivate the interior sensors (3-clicks and hear confirmation beep) I can leave the sunroof open. I'll add the alarm sensitivity to my next preventive service list. I figured this was atypical otherwise there would have been lots of comments on this website.
Any update on this? I recently started to have my alarm go off at night all at random times. This has happened 5 days in a row and as far as I can tell, nothing is even near the car when this happens.

Dealer is looking into it with Maserati technical group. This must not be a common problem. I take it in for 4 software updates next week, I'll let you know what I find out.
Every thing has to be closed: sunroof, windows!
I think for me there is a defective motion sensor in the interior window pillar. Few people seem to be having this problem. I've not heard if there is a detuning of the sensitivity, but for now ... 5 clicks / horn blows when I lock the car resolves the false alarms.

An update, my dealer ordered a new part for me and said there is also a software update that may help with this. My car is an 11/13 build so it may have something to do with it too. Once the part comes in I will let you know if it helped.
I shouldn't jinx myself, but my problem went away after dealer service. And the dealer nor Maserati NA technical were aware of any software fixes.

Dealer completed 4 software campaign updates and adjusted the drivers window to better align when closed. For over 5-months I have been doing the 5-click lock method and have not for last 4 days. Won't know for sure, but either window was putting pressure on sensor column area or there was something in one of the updates.

Mine is 12/13 build.
Alarm went off while driving

Hi all,

New to the group! Still getting my sea legs and trying to figure out exactly how to navigate throughout the forum.

Ready for this one ...

I've experienced the same thing with the alarm sounding due to the wind coming through the sunroof while parked/locked, BUT the weirdest thing happened to me yesterday. I was doing appx. 45mph, when dodging a pothole my car alarm goes off. I pulled over, turned the car off and it didn't stop. Locked, unlocked the car with the fab, still wouldn't stop. It cycled through twice, then finally stopped.

I've never had my car alarm go off mid-drive. Has anyone ever experienced this? When I call the service department, they like to blame everything on the car needing a software update.

2017 Ghibli SQ4

Yeah, mine has gone off before while driving as well ('17 SQ4). I was doing about 40mph is light traffic and for no apparent reason it decided to go off. Pulled over, couldn't figure out how to get it to shut off. Finally it seemed to stop on it's own. I didn't report it to the dealer due to my other experiences with this dealer... If they can't duplicate the error they will do nothing.
Is this just with the 2017 year? right now my 2014 SQ4 is sitting outside my work with the sunroof open, & windows cracked & no alarm. I keep it that way at work due to the heat (I'm in Arizona).

It's most typical with the earlier years .... 2014 - 2017. It happens to mine if there is a breeze/wind or vibration, (like a parking garage), otherwise it doesn't happen. My standard protocol is to deactivate the interior pressure sensors if I leave the sunroof open or crack a window versus have it go off in the parking lot.

A very old post, but where / what are the interior pressure sensors?
They are located in/around the windshield pillars between doors. Sometimes just having drivers or passenger door's glass misaligned will make the sensors more prone to activate. Mine would go off randomly, (high wind or vibration), until service adjusted the drivers side door window to not be as close to the pillar.
I suspect it's like a glass break sensor in home security. Problem is just cracking the sunroof on windy days is enough to trip the pressure sensor ... at least on the older models.

By the windshield sounds like the a-pillar,but between the doors sounds like the b-pillar. I'll check both unless you see this and let me know. ;)

Did you end up disconnecting them to solve the problem?

Exactly!

Exactly!
No need to disconnect. After adjusting the window to not be as tight to the window pillar side it solved my problem. BUT ... leave the sunroof open or vented on windy day it will set off the sensor which is to be expected unless you press the key fob lock button 3-4 times until you hear the confirmation beep.

OK, dumb question... how are you adjusting how tightly the drivers window is against the b-pillar? Are you adjusting the door latch inside the door panel ?
I don't have the specifics other than the service tech adjusted the window glass within the panel and replaced the window gasket, (as he could see the window was making a dent in the rubber gasket material).
I looked in the service bulletins and didn't have much info other than "adjust window on drivers side front". See attached.
