Default Electrical issues

I’m hoping someone can help with the following. I have a 2015 Z06. I’ve had an intermittent issue with the below warnings for the last few months and now the lights and warning’s are permanently on. Service Stabilitrac, service rear axle, service suspension system and service power steering. The battery is new and alternator tests ok.
any ideas out there.

Check the battery negative connection. Look for a thin black wire that should be on the connection.

Try taking off the ground at the battery and short it to the positive cable for 3 min. Note no connection to the battery negative when doing this!!!
this is a hard reset and may clear up your problems

The GM dealer had my car for two days and couldn’t find the fault and said they can’t fix it?? Time to buy my own scan tool.

How old is your battery? Marginal batteries (which test fine) do wierd things to the electrical system.

This happened to me with Ranger AFM delete other than that it’s always been a plug wire off but that causes loss of power and sometimes a miss so make sure all your plug wires are on tight on both ends the ones on the coil packs will click twice when putting them on. The ones on the passanger side you need to pull the fuse box to get to. A good scan tool will tell you if here are any misses and which one good luck

Use a DVM on amps, connect in series with the negative battery cable, everything off for 30 minutes, read current draw, should be below 50 mA, if not then start pulling fuses until you find the one that is causing the excessive current draw. Attack that circuit!

You could also use a 'clamp on' amp meter on either battery cable and repeat the above test if the meter is sensitive enough. It should work because it sounds like you have a large current draw taking place.
