jkm41 said in your other thread to pull a fuse, i think it that would be fuse 9 underhood fuse block, but this might interfere with lighting.

Are you able to start the car when the siren is going off?
Next time it goes off, try locking then unlocking the car with key itself not using the buttons, this might mean one of the sensors are bad.

You will have to read your warranty paper work to see if your still covered. It should tell you the date and mileage that you have to meet to still be covered.
