While i am loving the sportback,i do have this on/off buzzing noise from the drivers door handle.Not all the time but on rougher roads and when hitting the resonating point.
If i tap my fingers along the door panel in line with the handle ( along under the silver trim) i here it buzzing ,however if i just put my finger on the handle to push it in slightly and continue tapping,it stops.Same lifting it slightly.
Yes,the rubber stopper is in place behind the handle,but the handle does seem to have some slight rattling loose play.
The other doors also have some play but its a well "damped" movement and has no noise.
If the rest position of the handle is pushed slightly further in /or held out it stops.
I am slightly reluctant to take this up at the dealers despite the car being new,its just that if the whole door assembly has to be removed,i am concerned about everything going back together without damaging the retainnig clips etc.I dont want to introduce more noises.
