Wind noise above 60mph - Page 2

gsrjc · 09-07-2010, 02:43 PM

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 exact same problem at ~60MPH and was wondering if anyone else has gone through this?

Also, gsrjc, did the heater box seal fix work for good or were there any updates? I want to suggest it as a fix when I take mine in.

Thanks.

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.

That's worse than I thought. A foam seal around a damper door stuck open is what we normally find, especially if the door is vacuum activated and doesn't close completely over time. But to have the actual heater box separate at the seam must mean that it is made from cheaper plastic that cannot withstand the temperatures generated in the heat exchanger, thus distorting the box and opening the seam/seal all along the joint.

Glad it's fixed.

By the way, do you know your post is over in China?

I took my GLK in on Saturday they took out the heater box and the seal was separating and bent. MBUSA is Ordering new heater box will install Wednesday. I'll keep you all posted on Noise. Im not happy with a new car going to service already.

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.

jc00210 · 04-10-2012, 10:53 PM

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.

jc00210 · 04-10-2012, 10:56 PM

So after all these years no more noise after they fixed the seal on your GLK. I hope they don't say it's my window seal next Ill be upset.

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!!!!!

My dealer had to order stuff from Germany so they kept my car for a couple of weeks and that's when I complained and got the two year free service.

WOW couple of weeks thats crazy. Good thing they gave you the extension. Well I just got my car back today so far no noise at all. Perfectly quite Im happy because I was getting worried. I guess the felt they placed around seal worked. Now the bad news my car only has 342 miles and my wife already has a small nail in tire. My bad luck continues. I took out nail at tire shop no patch needed it looks at if it stayed in the upper tread. I guess Ill find out tomorrow morning when I wash the car if my tire is flat.

ble2716 · 04-14-2012, 10:08 AM

Glad you have that noise fixed.
I know it could be very annoying.
Thanks for keeping us updated.

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?

yaester40 · 04-19-2012, 12:31 PM

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.

GLKDC · 04-27-2012, 11:45 PM

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.

jc00210 · 04-28-2012, 06:20 AM

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.

Yes the noise has been corrected felt placed around heater box seal.

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.
