What year is this? On my 2012, second day found the negative battery was loose, I like to coat this with silicone, screw was tight. Removed the cable and the both and hand filed that terminal so would be a gap in it with a tight screw. Somebody is putting a positive battery terminal on the negative, the negative terminals if 50 mils smaller in diameter than the positive. Only took Chevy three years to discover this. For top terminal batteries, been this way for years so you would not reverse polarity, really had problems trying to install a negative battery terminal on the positive side.
But this was not the only problem, battery cable is not pretinned and crimped into the terminal, that oxidizes causing voltage drops. I drilled mine out by the crimps, cleaned off that corrosion, and soldered it into the cable, not only the negative, but the positive battery terminal as well plus the other end of it with that eye terminal.
With those five positive battery terminal outlets, just wired brushed those and coated with silicone to help retard corrosion.
But not the only problem, ignition relay contacts, brass plated with silver that not only oxides but sparks eat holes in it. In my lab, can use a constant current source, run 30 amps of current, pulse the solenoid with a pulse generator and use my digital scope that shows both low and high voltages and really get a jagged waveform. not good for getting a clean power on reset voltage to the some odd computer circuits in the Cruze. Contacts were burnt, cleaned them at first and replaced them with a Panasonic relay. Have this thing about stuff made in China, other relay that was showing problem was the high speed radiator fan relay.
As an old time engineer with a couple of minutes of experience, would not be a problem if they used tungsten for the contacts, does have slightly greater resistance, just use a slightly larger contact.
Problems really started back in the late 80's when our lovely EPA banned electrode plating in our country, guys in the switch departments were going nuts. Clinton partially took care of this by bringing China into the picture without much though about us loosing our jobs.
