OK, even though it's three years old, I have to add my theory.
Have you checked with you local psychic to make sure no one has cast a spell on your Subaru?
Have you checked to make sure there are no aliens using a tractor beam on your Subaru?
Have you noticed black helicoptors hovering near your Subaru?
I just wat to add this:
Have you noticed your left foot is resting over the brake pedal everytime you drive?
