Few questions, do you have a remote start? Did one used to be there, now removed? Do you keep any remotes in your pocket with a lot of keys, or other "debris"? Other than that, low battery voltage, poor grounds, defective GEM module, or light switches could be a culprit. If its a remote thing, your dealer can tap in to show "alarm events" to see if it was activated by the remote or one of the on board switches.
