Does anyone know if the problem some '17 MY had with dead 12V battery has carried over to '18 MY? Mine died yesterday and had to be flatbedded to dealer. Dealer said the 12V battery was so dead it wouldn't take a charge so they replaced it. I had to hook up a charger just to get it in neutral so it could be rolled out of garage to load. As you probably know, when the car is left in neutral, it can't be shut off. I'm sure that was what completely drained it cause I had to leave it in neutral for the trip to the dealer so the tow driver could roll it off the truck at the dealer. I didn't go with him so I don't know how long it set with the car in neutral. Unfortunately, I had just a couple days earlier self-installed a charge port light from GM but I had to ground it under a bracket bolt and the dealer is saying that is what caused this to happen. Sorry this is long but it is involved. I don't think what I did caused it. Any and all thoughts are welcome.
