I own a 2001 monte carlo SS. I just tried starting it but it didn't start. The lights on the stock stereo and on the gauges started flickering and weird noises came out of the speakers. The output on the stereo said "error" and the output on the dashboard said "service traction system" and also later on it said "service vehicle soon". Any ideas on what could be wrong? I hope its nothing too serious.

Thanks for the advice.

 

That's a scary list.
I'm sure glad you didn't write: "Everything makes noise but the horn."

The first thing you should do is: Check the Battery.
