you have a low voltage problem. either a bad battery or a brake in a wire somewhere. My sister had the same problem in her car. Had it to the gm dealer 3 times they couldnt figure it out. I put a new battery in, new wire from batter to starter, and a new altenater and wires to it. just by dumb luck i noticed the (+) wire from the bat to the fuse box under the hood was broke at the fuse box. Put new wire on it and 2.5 years later no problems.

Go to a auto zone /pep boys/ ....some auto store that has a Computer cable that plugs into the calbe jack under the steering collumn.. You will see it looks like a chip slot of some sort... Once the cable is pluged into it , it acts as DORMANT.... you will then be able to remove key from ignition. As for lights trippin and hazards and stuff flashing... well thats the alarm theft system that has to be reset... And thats where im at dealling with my CTS 2005 ....lol
