I was driving this morning and out of nowhere, my radio starting making the loudest noise I've ever heard (x3). Louder then a darn gun shot. I almost had an accident because I thought the truck was exploding. Had to slam on the breaks and jump out. Dealership was no real help, so had to walk all the way home to get noise canceling headphones so I could reenter the vehicle. Re-entered to a burning smell. Called Ford and was told to try and remove and reinstall the battery. I did this and it fixed it, but now driving with noise canceling headphones and can't have anybody in the car out of fear for hearing loss. Sitting here at my desk with ringer ears and bad headache.
