Finally had enough of the Hummmm......

That high pitched hummm that many of us have experienced. Mine came and went. Sometimes it's louder than other times. Seems to get louder as the weather gets cooler. I didn't really notice it during the summer at all, but lately, I can hear it all the time. It's a high pitch humming noise coming from the rear. Doesn't seem to be tied to acceleration. So yesterday, I finally took it into the dealer after suffering from it off and on since the car was new. They listened to it, and proclaimed it was a faulty fuel pump. Job should be done in the morning. Hope that cures it once and for all.
