am here to see if anyone is experience the same problem am having with my 2015 c7 corvette stingray. in the past I had issue with the infotainment OEM and had to get it replaced. with that problem when I turn off my car the screen would be on for more than 10 minutes causing it to drain my battery. so I had to buy a new one and replaced myself but broken off the battery current sensor and had the dealership patch it up. now after a few years it works fine when am driving but after am driving back I would experience my car pushing hot air, the radiator fans will be on while the car is off but would be on for more than 30 draining the battery so I have to disconnect the battery and reconnect causing it to reset. the new thing am seeing a few time is my engine temperature gauge would drop to 100. I don't know if it's a cooling problem or just that battery current sensor. just need help on this issue since the dealership won't know since it doesn't trigger the check engine light
nevermind I mean I have a broken ground strap Cable that the dealership patched up and is that something I need to fully replace

A broken current sensing transformer wire will not cause what you’re seeing…also not all P or Powertrain DTC’s will illuminate the MIL so you will need a scan tool to check…type B DTC’s have to fail two times in a row for the MIL to turn on…for a P0117, 0018 or 0119 you can see what happens when either of those 3 DTC’s set…cooling fan commanded on, ECT gauge inoperative and AC will be off…seek out an automotive electrical specialist in your area to diagnose this.
overheating/electrical problem
