I have a 2018 Ford Fusion SE 2.5L , 137k miles , the engine runs like brand new . but whenever it’s idled in park is had a bad shaking and humming noise in the cabin , and whenever it’s gear , it gets a lot worse , like it hurts your ears . but it’s only whenveer it’s idling , if i start driving it goes away …. what could this be ?

can someone send me the carfax of a vehicle i’m looking to buy ? i’d really appreciate it
