Yeah, what i heard is sometimes around that area. Cause i really can't find the exact place but mostly i hear i suspect at that area, mine case is not high speed, high speed the sound don't come out, is low speed that rattle sound comes out. 20-40kmh on smooth road also comes out, like minor vibrate of the car makes the sound.

Next service have to check it out. Hopefully no need to dismantle the passenger door cover. Affraid it get's worst

actually i found out it's coming from my sunglass compartment . the one on top middle. yeah i found it hard to believe as i kept hear from passanger side but it really is the sunglass, so if u have anything in it, remove and see it helps

sounds like steering button buzzing noise to me. One of the common issue of Cerato.

U try to put your ear to the steering left side button group. Many say is the call GREEN button, u try to press/hold the button when u hear it.

Mine is the Mode button.
