It could just be a bad battery connection but it could also be a bad starter. I would start by cleaning and tightening the battery connections.

Check that 60 amp fuse underneath the backseat we had the same problem and it's solved it

And that does make sense because GM's have common issues and recalls at that interlock area where the ignition switch and key combines,

It wasn't the ignition switch...

For us it was the fuse block under the rear passenger seat as well. When the mechanic took it out it was toast. This blog was very helpful to diagnose it thank you.

For me it was the internal mode switch which is located underneath the transmission oil pan connected to the lower control body valve it's sold as a whole assembly or you can get it separately from a dismantler at a local wrecking yard. I had to remove and replace the internal mode switch after doing that everything worked fine. there is no neutral safety switch on this one because that is the 4T080 e standard transmission and the regular standard one has an neutral safety switch located above the transmission located on the control shifter but the 4t80-e S5S transmission has an internal mode switch located underneath the oil pan and lower body control valve which initiates and indicates a dashboard selection for a shifting mode on the dashboard thanks everybody that was what solved my problem cars lives matter

These cars have two recalls for electrical issues, I have seen posted on kelly bluebook but if i had already checked all fuses and all possible relays, plus battery seem to be 12volts, i'd see if i was at least in park and test the starter at twelve volts with a multimeter from a local auto parts store, depending on the issue you may have to clarify more what your seeing
