07 Chevy Cobalt

I have an 07 Chevy Cobalt and just recently I’ve started having problems with it. When I start it all of my indicator lights come on as well as messages on my dash that say my traction is off as well as my ABS. All of my gauges go crazy and my power steering goes out as well. When I took it to the dealer they said they had never heard of this problem before and also couldn’t help me with it because the computer in my car is no longer under warranty.
