I have a 2015 TEP with 2800 miles. For quite some time I've noticed the stereo would be at a normal volume and would then reduce in sound, almost as if the speakers were not grounded properly.
Is anyone else experiencing this? And if so what was the problem?
Thanks
Yeah, go into options, and you can turn it off if you'd like. It gets louder because of engine noise and quiets down with it. I can't remember exactly what it is called.
its in there, i turned it off too
Found it,
About Automatic Sound Leveliser (ASL) ASL automatically adjusts the volume and tone quality according to the vehicle speed.
I think that has everything to do with the radio signal drifting from an HD Radio signal to Analog?
