I don't know if its just me but the stock alarm for my GT sedan doen'st work. Shouldn't the alarm arm itself after i leave my car? One day i come bcak to my car only to see that my sunglasses and other stuff were gone. I also can't seem to set the alarm off, i lock it and try rocking the car, pull the door handles but still it doesn't go off. The brochere says the GT comes with alarm system but is that just the panic button?
