Has anyone else had this problem?

I just bought a 2012 C63 AMG and when the windows are down at around 40-60mph, if the wind is gusting right, there is loud high pitched wind whistling noise coming from directly behind my left ear.

It sounds like it might be related to the seatbelt or somewhere around there but I've tried everything (holding seatbelt, riding with seatbelt off, riding with seatbelt wrapped around the back of the seat, putting arm out the window, putting entire hand out the window, putting entire arm out window while waving hand frantically (pretty amusing sight)), but the noise persists.

It doesn't happen all the time, but when it does its loud and its annoying. It happens on the passenger side as well.

Anyone hear of this? I tried searching for "wind whistling", etc, and didn't find anything in this forum.

Yep... my car does this and the C63 I drove in December did it too.

Ugh, really? Where is it coming from? No fix for it?

Varreth

Yes! In my '12 Coupe. Very annoying and seems to be worse with the roof open. If there's a bit of a cross breeze it wails/whistles like a banshee. Actually scared me a bit the first time it happened.

Me too, its so loud I can't drive with the windows open at all. I've also tried to see where its coming from and I can't isolate it. Has anyone else found a fix for it?

Mine whistle when cruising at >80km with all windows closed, will bring her back to the dealership to be fix next Tuesday.

ClemsonJeeper

Nope. Its the same for me. Makes me not even want to drive with the windows down unless I'm blasting the radio to mask it.

Has anyone asked the dealership whats going on with it? Seems like a design flaw, but I can't for the life of me figure out where its coming from.

My coupe does the same.

Dang! Now I gotta go test this! I am pretty sensitive to this type of noise etc...and that will drive me crazy! Although most the year here in AZ is window up AC on weather.

strange nothing like this on the '08-'11...

I have a very noticeable whistle noise with all windows up when I cruise at speeds above 90mph. It seems to be coming from the sunroof. I had the dealer change the seal but it is still doing it sometimes.
I am glad I do not live in Germany as cruising at that speed is not appreciated by the authorities in this country.
Any recommendations would be greatly appreciated.

Mine too, bad in a crosswind. If I hold my hand along the bottom of the outside mirror I can get it to stop. It is very annoying ! I agree that sometimes it is so bad I want to put the windows back up, too bad...

my car has a whistle between 100-120MPH it's weird, I only realized this today, and is a high pitch. I believe it comes from the center windshield area. that what it sounds like. Any idea ?

I'm bringing my car in for head bolts replacement and would like to get this taken care of.

My coupe does the same. Meh.

lol my car does this too it sounds like the birds flying from the Angry Birds game

So it seems a lot of people have the issue - has anyone talked to the dealer about it?

Not likely that they can do anything about it though...

+1 for 2010

I think it is a coupe issue.

ClemsonJeeper

Yeah, I didn't mention in the first post that mine is a coupe.

-=Hot|Ice=-

I think it's a flaw in the design of the car, and the way the air is channeled behind the seatbelt. so I don't think dealers can really do anything about it anyway.

Mine is a sedan so it is not only coupes

Hi All, obviously new here but have been lurking for a while. Has anyone found or know of the solution to this whistling problem? Called my local MB service center here in Australia today and they claimed that it was the first time they heard of this issue. I Find this hard to believe when it seems to be a common problem across all C Class Coupes. I first read about the problem on this forum prior to buying the car and was just interested to know if MB have recognized there is a design flaw and if there was a fix. Has anyone here contacted MB customer service and received any feedback? I did ask the dealer to email MB on my behalf & they refused to unless all their checks are carried out first. I'm taking in to the dealer next week. Apart from this the car has been fantastic! No other issues at all, knock on wood.

This is funny, but my new 507 does the same thing. I have purchased artist grade black masking tape and have taped the gaps in the mirror and voila, no noise. A 90 thousand $ car with masking tape on it
I tried to tighten the mirror gaps down but was afraid to screw something up.

My sedan does it only when the roof is in tilt at certain speeds, exact same spot as you described.

i did not have a loud noise but a faint one above the driver's side from day 1. the tech removed and reseated the roof rail, applied some lube, and the noise went away.
