<p>My 2007 has killed two batteries and must be disconnected between drives because if I do not disconnect the battery the car will drain it in two days. The radio is not being left on, nor are any lights on. I have taken it to the Porsche dealership twice for this and they find nothing. No codes. No alternator issues. No answers. I have heard stories of the front control unit going on the fritz if the front lights were buffed when washing and drying such that it created a static charge. Dealership knew nothing about this, but it was prevalent on many blogs when these cars first became available. How can this car be draining the battery in just two days when not driven?</p>

<p>TIA for any answers, or ideas.</p>
