Whats really crazy is I had 15 miles on my car after i purchased (last week) and I was standing outside the car while the car was running, and I had a weird almost TRON noise whining coming (high piched alternating freq) from the car... the only thing i can compare it to is when the first time i saw a Fiskar Karma electric sitting at a stop light.. very strange un-explainable sound.. almost thought something was wrong.. I have not heard it since and I now have 250 miles on the car..
