I've had it for a couple weeks, and had few issues. But about one or two nights a week, after I park in the garage, plug it in, and lock it - I come out hours later to find it awake and playing music (as if I were siting in the driver seat). The garage is even warm because the A/C has been running and the car's putting out heat. The keys are stored ~20ft away inside the house. Has anyone else had the same thing happening?
