Good point:Heh, you might want to search for the threads for loose battery connector. I recall reading quite a few people having an issue with a terminal block involving the 12V battery. I forget if it's located in the engine compartment or near the 12V battery itself in the rear of the Volt. This connector being loose led to many weird issues. Amusing that GM is suggesting looking for it. Maybe they should issue an advisory or something to check for this first when strange symptoms arise.
