Parasitic Draw
My battery keep dying. I had a friend check it and he said I have a parasitic draw that’s why the battery keeps dying. Some module is drawing power but doesn’t know where. It would not code. Any ideas ? I have a 2010 C6 Grand Sport. Also, I have a squealing noise he thinks it’s the pulley. The crankshaft is wobbly. Possibly related ? Thank you.

Same problem with my 2011 GS.
Pull the OnStar fuse (located in the passenger side footwell area fuse panel) and I bet your electrical parasitic draw goes down to next to nothing.

As far as the wobbling pulley .... You are going to need to replace the Harmonic Balancer (common problem with the LSx engines)
