2011 Chevrolet Cruze - Electrical glitch

no crank no start, started with dome light not working when driver door open, no door ajar message, radio not turning off when door open, onstar coming on when you open the door or tired to start car and I do not have a contract with onstar. unplugged the fuse to onstar and the radio stopped working

I am not a mechanic but I’d start by having the battery and alternator tested. You may have a bad Body Control Module but get the simple possibilities out of the way first.
