Okay here goes I got a 2015 Malibu I have replaced both batteries ,starter, alternator, battery control module(I'm told this going out is what caused the other two items to go out ) anti-theft control module, it's got a new key( because of course I broke the key in the process of trying to make the damn thing start when everything else was going on) and the stupid son of a b**** still wants to turn off and not come right back on sometimes leaving the key on for 10 minutes turn it off and then turning it back on to reset the anti-theft sometimes works but sometimes it just stays off as long as it feels like it and then it comes back on and acts like nothing's wrong can someone tell me what I need to check please please I cannot afford to take this back to a shop I
 
Why do you have more than one battery?
Do you have a code reader capable of showing all codes for all systems?

This model year has the start stop feature it has two batteries and a battery control module that allows one battery to be used while the other battery is charging I think it's stupid too not showing any codes at all

Does your scan tool read codes related to the charging system or only engine codes? It sounds like you are just throwing parts at it and not following diagnostics.
 
No I am working with a shop they have fouled all the codes the battery control module was going out and it caused both batteries to go out and the alternator and the starter went out because okay it's a few years old broke the key had to replace the key and the anti-theft control module but it is still doing the original problem every once in awhile turn it off it doesn't want to come right back on again if you go through the motions of resetting the anti-theft system by turning the key on leaving it on for 10 minutes turning it off for 30 seconds it will start right up that's why I'm calling it a possessed car the shop cannot find any codes being thrown it only wants to do it once in awhile they kept it two weeks and it did it to him one time in 2 weeks and they don't know why they're trying to tell me to change out the brain for $600 but they can't guarantee that will fix the problem

Has the shop checked Chevrolet technical service bulletins?

I am honestly not sure about that they're just saying that it's not showing anymore coats it's not showing that anything is wrong I have a printout that they gave me I will put a picture of it on here later when I'm not at work

Ask them and consider trying a GM dealer
