I have owned my GLA250 for more than 15 months andalways had wind noisefrom both front windows (as if the window is not fully closed). On investigation it appears that the wind is getting behind the window seal, especially noticeable at the top back corner, simply lifting the rubber seal around the door frame the wind noise increases significantly.I emailed Mercedes Customer Service nearly a year agoto which theyreplied "We are unaware of any issues with wind noise on these vehicles and would recommend that you arrange a time for your local Mercedes-Benz Retailer to investigate this issue."6 months ago (Jan 2015) I took the car to my localretailer to investigateand replied back to Mercedes Customer service with the following email:I have since taken the car to my local dealer for investigation into
the side window wind noise and requested a GLA courtesy car whilst
they investigated the noise. I found that the courtesy car had
exactly the same issue and therefore can confirm the wind noise from
the side windows is not specific to my vehicle but inherent in the
More than 90% of my driving is at motorway speeds which is when the
noise is most noticeable and at its most annoying. Every other car I
have had (or been a passenger in) is quieter than the GLA for wind
noise from the side windows.
Being a brand new model I'm sure Mercedes-Benz accept there are likely
to be a few issues to rectify. My preliminary investigation suggest
that the noise is coming from between the glass seal and door frame
and not between the doors frame and car body. I have found that a
slight movement of the rubber seal can cause significant changes in
the amount of wind noise. I also note that the side window seals are
all rubber rather than the rubber/fabric seal seen on older
I am providing this information to bring it to Mercedes-Benz attention
in the hope that this will be rectified, as I am getting frustrated
with the car.
I would very much appreciate if you could confirm that Mercedes-Benz design:-
a) are aware of this issue,
b) will or have investigated this issue,
c) have confirmed this is an issue,
d) have resolved this issue.I did get a call from Mercedes Customer Service but no follow up email.I have now booked the car in again with my local dealer to further investigate.
