    Post Car Starts but key won't release

    I have a 2003 CTS that starting acting up on me. I disconnected the battery and then reconnected the battery again. Started the car right after, then my key wouldn't release. I had got the "Service Theft System" on the DIC and also notice the Traction Control was lit up, the Service Theft System, Fuel and Temperature gauges do not work and the DIC does not give me any information about MPG, etc etc. and the shift column does not display if its in gear or park. I can't shift my gear out of park also.
    It was running perfectly fine until I dc the battery. ( I dc the battery because I wanted to try to hook up some speaker wires. after it didn't work I hooked the battery back up).
    The battery is brand new only a few months old. Changed my terminals and my ground is good. If anyone could help me with this matter I'd be greatly thankful.

    I had the exact same thing happen to me. Took it to the dealer and it was my ecm. Currently waiting on the part right now. Been waiting for a month so far and will be possibly another month. But I'm in a loaner xts for the time being.

    Hopefully it's not that! The part alone costs like $400!
