My neighbor told me he's been hearing car alarms several nights. I thought it was a neighborhood car, but as I was leaving my house the other night I heard my car ringing. I should point out that I only have a basic car alarm coupled with the horn.
So...
She's in a closed box
No movement
No open windows
No vibrations
It is new (400 km)
Doors well closed
No trace of it ringing after it happened (no flashing lights, etc...)
I try to charge the battery, but it doesn't change anything.
And a few times a day... it rings. Has anyone ever had that? My garage is quite far from home, I would like to go there for that... can you help me?
Hey. I had this happen to me a couple times. I figured it was the wheel lugs loose. It has the anti theft sensor. I got Costco to retorque. And it fixed the issue.
Has your car had all the latests software updates? If not, that could be the issue. Random unexplained alarms were somewhat common on 12c's, 650's and early 720's.
Check and see what phones are linked to your car - maybe for some reason, there are other phones linked to it and it is ringing through? I know once, I was in the garage working and had music playing through my bluetooth speaker system in the garage and then it stopped...but somehow, someway, it had synched to my car and I was unaware of it. I kept playing w/the speaker in the garage trying to get it to synch. So I got tired of it and decided to call a friend that is a lot more techie than I am - I could not hear a word he was saying. When he called me back, the ringing happened from inside the car, and that is how I realized what had happened. No idea how the ignition came on by itself but I had the key in my pocket. It has never happened again.

does it do it mostly after parking it from a recent drive? cooling noises perhaps?
try pushing the door in once closed,could be just a latch switch not being satisfied.
and unfortunately no, most dealers do not necessarily do all software updates before selling a car. you'd think they would but noooo....!
Three ideas, thank you:
1) no it's really the car's clackson that starts for 1-2 minutes, and then stops.
2) ok good idea I'll try to push the door again
3) I'll contact the dealer
Did anyone resolve this Phantom alarm problem, with a computer update?
Last night around 4 am my 720s started having a panic attack, out of the blue the alarm starts going off, lights flashing and beeping - there was no vibration or movement in the garage (reviewed garage cameras and it’s clear that it just randomly went off) then about 2 minutes later it turned...
I tried to find Eric K's post on this subject since I think my issue was the same as his. So the GT2 RS is in the garage getting a full custom wrap Xpel Ultimate Plus and then Ceramic Pro (4-coats, Gold) so I had the move the 720s out of the garage to give the guys more room to work. It rained...
A question for those of you who've had that phantom alarm problem before.
Is there anything I can do to avoid this before I go to my dealership? For example, if I don't close my 720s (in my box), it automatically closes, doesn't it? Does it prevent from ringing?

you always need to fully close it so it shuts down ... otherwise will also drain the battery over night ... best is to set it to fold the mirrors so you see when it’s fully closed.
Well I wrote an email to my dealer... explaining these phantom alarm problems. He just told me that a pair of door locks have been ordered for me and he offers me a date to replace them. Without seeing my car….
So the problem is well known.
Thanks to you and the forum for the support and sharing of oppinions. You are the best. Greetings from Switzerland!!
