I’ve got this dreaded 3G car alarm issue where it randomly goes off for no apparent reason. I’m at my wits end. I’ve searched this forum for weeks to come up with the fixes I’ve completed thus far. I read how one guy simply sold his car. He was that sick of the problem. I laughed. I’m not laughing anymore.

What I’ve replaced with new parts so far:

* Power door lock actuators in all 4 doors
* All 4 black “dome light” switches in door jams
* New trunk lock/latch
* New hood lock/latch

At this point it’s becoming an issue of what’s the car really worth. If it costs $1,500 at the dealer to diagnose it then forget it. Consider it one more TL going to the scrapyard. Other than this the car is in perfect shape but I cannot have the cops called on me every night (and I can’t leave my doors unlocked), and I can’t have it going off at work anymore. Security is pissed.

What else is there? I’m tired of throwing money and parts at it with no real idea for what the reason is. So far a lot of people have ideas about how to fix it from reading the forums but these people haven’t really had the problem themselves.

Any help is extremely appreciated!!! I’m tired of disconnected the negative battery terminal everywhere I go. I thought of putting a kill switch in it... but one shouldn’t have to do that and it’s pretty extreme.

 

One thing I forgot to mention: twice over the past three months the starter has hit a “dead spot”. The car has total power but it won’t turn over. It’s like there’s no power at all going to the ignition. One good whack to the starter with a steel rod and it started fine both times. I’m assuming the starter is tied into the factory alarm system. Could this be an issue?

Also, sometimes when I turn the ignition key it “buzzes”. I turn it off and try again and it will start. Both the buzzing and the starter not working are very random and have happened only 2 times but the alarm goes off every other day. And when it goes off it goes off repeatedly.

Man I hope someone knows something about this

 

Changed the batteries in the key fobs too
