Firebased, I understand the car is under warranty and you say you have not received any satisfaction from the dealer.
Have you taken it upon yourself to try to figure out the problem by learning how to diagnose the electrical problem?
It seems to me all the time spent video taping the dash noise and driving to dealers and bitching here on the form you could have figured this out many times over so far.
If you are not electrical savvy or have no mechanical background you must surly have a friend that has some experience.
You do have friends don't you?
Best of luck,
