I have a 2016 Impreza Limited with 100k miles.
Recently I have noticed that after getting up to speed I hear a droning sound coming from what sounds like the rear of the car. The sound is similar to that of a propeller driven airplane. It does not get louder under acceleration or quieter under deceleration. The only thing that changes is the frequency as far as how fast or slow the noise is, and a small amount of pitch fluctuation. I don't think it is exhaust related as it doesn't matter what the engine speed is.
Any advice is appreciated, thank you.
