I did not take the first occurance seriously. But I took the car to the Ford dealership where it was purchased after this second experience. They ran diagnostics and could not replicate problem. They checked with Ford and other dealers to see if anyone else had a similar experience or if it had been reported elsewhere. Not help to fix problem. Still happening.

Will be driving along with radio turned off. With no warning or interaction, the radio turns itself on to a local station and the volume is very loud. Scarey, irritating and distracting.
