I have a 2005 Suburban. I hear a chirping sound (like the alarm chirp) at random times while driving. It it intermittent and random. It sounds like it is coming from in the dash. Sometimes while I turn the car off it chirps slightly 3 times. The last episode was while driving a long trip. It started chirping about every 30 seconds. I pulled over, turned the car off, restarted and the chirp dissappeared. I need help.
