So a newer Roadster here and I have a question, hopefully you can help me out with. 2010 Tesla Roadster Sport. I have not drove the car alot, But went for a 10 mile drive last night and noticed when I went out to the garage later in the evening it was humming from the PEM box. This morning I went out and it was still humming. I got in and it had a 12v Battery warning on the screen. I assume The PEM running is draining the 12V battery. The PEM was warm to the touch this morning before the drive cycle. Any advice would be appreciated! The battery was able to start the car as well this morning, But was low.
