2015 3LT Base Coupe has intermittent buzzing sound/static. This happens regardless of whether the radio is off or on. Sounds like it is coming from the electronics. Car has Navigation, etc. as 3LT package.

My 2016 3LT is doing the same thing. Even after I shut the car off, I still hear it until I open the door. Did you ever find out what was causing it?

Interesting! Never heard any noise like this. Loose ground somewhere?

Not sure but it is definitely the small speakers in the door. Guess I'll pull the panels and look further into it. Don't understand how speakers can put out static sound even when the radio is off. Maybe the car has been bugged!! LOL!

Try pulling fuse 21 in the rear compartment fuse box. It's for the amplifier which will help narrow things down.

JefferyFrame is on to something. Understand run-flats (have them on other cars) and type of road you are driving on. I live in same area as the OP. First Vette 22 Z51. Real bad road noise. DB meter would hit 91 on the freeway. Two trips to dealer and can't figure it out. Fast forward a year later and took delivery of 23 ZO6 with bigger tires and she runs quiet like a Benz (except engine symphony of course). Both cars HTC. 2 cars, same conditions, one loud as heck and the other quiet. JefferyFrame makes sense and if I had the problem I would look there first.
