DOSE IT HAPPEN WHEN YOU'VE GOT A FRONT SEAT PASSENGER OR TRAVELLING ALONE ??? Happens every time i dont have a service tech in the car from toyota, held the seat belt while driving applied pressure to the window, applied pressure to the seat belt....... Been to toyota three times, two our three techs have herd the noise, but the main wants me to bring the car in, he is going to be doing it himself, as he is intrugued the rattle is coming from the drivers side B piller so the seat belt is plugged inn, and it right in your ear........ hoping to have it sorted next week................
