Complete electrical failure, a danger while I am driving. The wipers go crazy, no radio, no signals, no windows can open so I can't even arm signal. I have no idea if my brake lights even work. This happened to me first and a module was replaced, luckily under warranty. Now it is happening all over again. The dealership has had my car now for 3 days and still no answer and I have yet to find out how much this will cost me. They really have no ideas...help!
