My ‘19 custom trail boss chirps when I am coasting down the road and I apply the gas slightly and then if I shift down manually I can get it to do it. I also notice it when I am on cruise control on the thruway and it applies throttle to maintain speed. Does anyone know what this could be? Almost sounds like a serpentine belt squeal. It’s hard to pick up on but you can’t stop noticing it. I would hate live with this sound on a brand new truck.
