UPDATED - head tech found the problem. The seal in the heater box needed to be replaced. So they put a new seal in the heater box (I guess heats the air that comes into the heating system???) and noise is gone so if anyone else is having this wind noise problem, ask the dealership to check on this seal. Part had to be ordered and car should be good tomorrow.

I'm having this problem on a E350 2011. 60-70mph whistling, whining noise. Slight but annoying. It also varies slightly with temp (slightly).
Apparently, you can troubleshoot this by taping zones until you narrow it down. I guess this is how the techs do it ; and they seemed to have solved that fellows issues in post above. My guess mine is something like that.
I'm going to tape off the areas myself. This way, I might be able to save some time (i'd hate to complain about something like this, as the sound is not loud; just annoying as hell
)
I'll post my fix, if ever it's fixed, here. Even though the car is not the same, it's probably related.

wow... seal was separated and bent on a new GLK... crazy. my service department gave me the 2 year free service deal to keep me happy so I haven't had to pay for any service A or B yet. Then again, my GLK was my 5th car purchase from them so maybe they did it so they wouldn't lose me as a customer. I'd ask your dealer to do the same since you have been inconvenienced for not being able to enjoy your new car.

Good Idea!
I think Ill ask for sure. I love the car I just can not believe my luck. It seems any car I buy has some problem. From Acura, Jeep , and now Mercedes. I expected better from such a iconic company. Hopefully it's the last of my troubles.
#36
So I take the car in today and they replace the entire heater box. I test drive car noise still there. They will keep car to place a felt seal around rubber seal MBUSA just released a fix. Funny thing is the Glk loaner they gave me makes no noise LOL. My luck is bad!!!!!

Glad to know this!
I noticed load noise at high speed when driving my new GLK 350, and reported it in J.D. Power new owner survey in 2011. But, I did not discuss it w/ the dealer. Thanks to the forum, I will take the issue to my dealer.

GLK Whistling sound highway
Has anyone noticed a whistling noise above 50-60 MPH on the highway? Can't tell where it's starting from, but it's not the sunroof. Any ideas? I got a brand new 2012 with 15 miles on it when I noticed.
#43
Provide them with the following update posted above. I made a copy and gave it to the dealer. Also make the service team ride with you. There is no denying a noise if you are in the car with them. MBUSA just put out a update and they are fixing the GLK with a felt strip around the heater box and it resolves the noise issues.
#44
Could you elaborate a bit on this? I have a noise that seems to fit this, and I need as much info as I can get before I bring it in. It's a little embarrassing (noise issues) as they could get an attitude I suppose, considering that it's so hard to pin down. If they where to try to ignore this, it would be unfortunate
(for them)
Did you finally get rid of the noise?

I have a 2010 had nothing but trouble with mine crack rim broken set tracks car been making wind noise from day one they don't want to fix nothing I went to every benzs delir in the south bay I am going to try Torrance benzs to see what they say about the wind noise

That's crazy call Mercedes national line and tell them that there is a service call for the heater box and your dealer does not have the update yet.

So they put a new seal in the heater box (I guess heats the air that comes into the heating system???) and noise is gone so if anyone else is having this wind noise problem, ask the dealership to check on this seal.

Gsrjc hasn’t been back since 2015 according to stats, so getting an answer is unlikely. Last production of GLK (X204) was in 2015 so it’s also unlikely Mercedes will do anything about wind noise.
On an older car, the likely causes of wind noise are door seals, seals around mirrors and windows, gaps in windshield seal, sun roof seals.
