Does anyone get a static sound, almost as if there was a short-circuit when the ESS kicks in to shut down the engine? This only happens when I have my speakers on and mostly when I am playing music through USB-C. I haven't tried regular USB yet, but have noticed it sometimes also when playing the radio. My guess it has something to do with the wiring and of course that sound is only transmitted through the speakers audio.

I read a forum post a week or so ago with the guy saying he has this issue also..

Maybe the sound of power disconnecting and reconnecting to keep your radio o while ESS is on? Maybe check connections like harnesses and speaker inputs, maybe have your dealer check factory amp and wires. My friend's trailhawk doesn't do that, yours shouldn't.
