I am an owner of the new gla 200 since September 2021. At highway speeds I have noticed a whistle like a wind noise coming inside the car cabin. Do you have a similar experience of this issue? Thanks in advance
This is typically an issue with a window/door seal. I treat mine with Gummi Pflege and it does help. But if bad enough the seal(s) must be replaced. As you have a new, under warranty, vehicle you should schedule dealership service, as reticent as most of us are to do so.
