Won't start

Actually it is not crazy and I will explain why. Your car/suv has dozens of computer systems and as soon as you put in they key the are turned on and using power. So as long as you have the key in your ignition, some of the computers are on and using power, the only way to turn them off is to remove the key completely. Car are very, very complicated these days, most 2010 cars have around 30-40 computer systems, many of which is more powerful than a desktop computer. Hope that this info sheds some light. When I work in the shop, I NEVER leave the key in the ignition, I put it on top of the dash with the driver's window rolled down.
