Rear window hissing noise

[Lamdon]

Hi everyone!
I'm new owner of QX70 3.0d GT and have issues with rear doors window insolation. There is a lot of hissing noice coming in at speed around 140 km/h. Anyone having similar problem?

Welcome to

Hissing noise = air leak noise to me.
Any chance of wind noise or road noise?
Only at that speed?

I did some sort of investigation and probably it's a wind noise ( air leak). Will check with local dealer if they can do something about it..
