This has been happening for a while now and I can’t figure it out. 2019 Ecoboost with HPP, manual. Every time I reach mid-high RPMs, after releasing the throttle, the car makes this strange buzzing sound. I can’t tell exactly where it’s coming from, but it’s audible from both inside and outside the car. It’s annoying when accelerating because every time I lift off the gas to shift, it makes the noise. It only happens in 1st and 2nd gear, and sometimes goes away if I’ve been driving for a while. Not sure what it could be.
