My car alarm has gone off twice in the past two months for no apparent reason. Both times it was around 11 p.m. (in my driveway) but there didn't seem to be any criminal intent involved. Is it possible an animal is causing the alarm to go off? I purchased the car new and this has never happened before. Anyone with a similar issue? It's causing me some concern, i.e, I can't sleep now!

 

Is this with aftermarket alarm? It sounds like it must be because the factory "alarm" doesn't go off unless you open the door while the car is locked. Also, I don't think there would be electrical problem already since it's an 06.

 

Check the panic button is not sticking on the remote...Just a thought.

 

quick question when you arm your alarm (pressing the lock button twice) does it beep? if it doesnt your car might be thinking your door hood trunk may be open. might have a bad door switch or hood switch

 

Found this, think it was from a TSB:
Security System Sounds by
Itself
Currently Applies To: ’07–08 MDXs, ’07–08 RDXs,
’05–08 RLs, ’04–08 TLs, and ’04–08 TSXs
When the security system sounds, the B-CAN stores
the last input (security breach history data) that set
off the alarm. If you’ve got a vehicle in your shop
because the security system sounded by itself for no
apparent reason, you can use the HDS to access
that stored history data to help you find and fix the
problem. Once you’ve found and fixed the problem,
you’ll then want to use the HDS to clear that history
data before you wrap things up. Here’s how you do it:
To access the last security breach history data:
1. Connect the HDS to the 16P DLC.
2. Turn the ignition switch to ON (II).
3. From the System Selection Menu, select BODY
ELECTRICAL.
4. From the Mode Menu, select Security.
5. From the Security Menu, select HISTORY
DATA.
6. Scroll down and select the last entry posted.
To clear the last security breach history data
after you’ve found and fixed the problem:
1. Return to the Security Menu, and select
HISTORY CLEAR.
2. Turn the ignition switch to LOCK (0).
3. Disconnect the HDS.

 

with aftermarket alarms I've seen them start to go off by themselves if the battery is dying. when the voltage gets below a certain point the alarm will think someone cut the power wire and if you have a battery back up it will sound the alarm.

just a thought with it being winter and the cold temperatures put a strain on batteries.
