Rhythmic vibration at 65-70 MPH

[jollow897]

Hey everyone, I've been running into an issue where there is a rhythmic vibration when I am driving 65-70 on the highway as well as when i turn left (even at low speeds) it almost feels like I'm driving over rumble strips. I can feel it in the floord and especially the gas pedal. Ive taken it to Ford twice and they said its a tire issue. Bought new tires (Wildpeak AT4) and got an alignment and its still there. Anyone have any idea what this could be? Happened to anyone else? '22 RWD XLT

@jollow897 any chance this thread is what you’re looking at? I’m having a similar hum/vibration from my powerboost on light throttle, under load, at higher gears. Dealership couldn’t not find it upon their test drive, but I wasn’t in the car to call it out.
