Take it to the dealer under warranty.

Mercedes, "The best or nothing."


The only thing I"ve experienced that has an airplane- propeller like sound is a faulty wheel bearing. I’d describe it more as a roar rather than Wuuuu …, but the thing w/wheel bearing noise is it gets louder the faster you go usually. Yours seems to quiet off after 50mph, so unlikely to be wheel bearing. I’d guess it is some sort of wind noise, check all the doors and windows that they are shut solidly. And take a look-see around the car, see if some trim panel or another has fallen off or come loose. roof racks are nortorius for this.

Warranty => dealer. If they claim ‘they all do that’, say ‘prove it’, drive another one.

Thank you for your nice comments. I would be happy if it is not the issue in relation to engine. The car is too good to get wrong. I will take to dealer soon.
