had my BS for 2 months now its got just under 180 miles on it , the dash by the driver side begins to rattle.
I have a rattle in the back of my car, it's the 3rd brake light rattling against the rear window.
I also hear a clicking/popping rattle,it sounds like taking a nickel and tapping it against metal under the passenger seat

 

Sounds about right. Sorry to break the truth to you but these cars rattle a lot. Search other threads. Your warranty covers all of this, but be careful if you pursue the dash rattle. I've only heard horro stories about it getting worse. Dashes aren't meant to be taken apart.

 

For sure, do NOT let your Dealer touch the dash.....you'll end up with even more rattles!

delete resonators put headers let the rattle feel unimportant lol.

 

Have occasional drivers side dash rattle/squeak too. I just hit accelerator harder when I hear it!

 

That's a folks tail, I had the dash apart in my w210 back then and did so on my bummer when I had it as well...just need to make everything is screwed in and in place...rushing the job leaves you will problems...with time things will rattle but a brand new be bs shoukdnt be making these noises...

 

Welcome to MB...

 

does anyone have a c63 that DOESN'T rattle?

i have the dash rattle and another one near the base of the windshield on the drivers side. it used to bother me a lot given the price of the car but i have since tuned it out. id rather have a couple minor rattles than have a mb tech make it worse with weeks of downtime

 

I've never had a car with a rattle like this, and to have a brand new car doing this is unacceptable to me.

 

So far my car has 16,000 miles and not a single rattle. Now that I said that, my car will likely start rattling today

 

My car had the same issue with the brake light. It was an easy fix. An additional rattle developed in the parcel shelf (in lieu of rear seats) which apparently was not designed like later models. That is being addressed as we speak.

 

My C63 never had a rattle

Take the car in and get an assessment. If you point it out, it can be addressed. Its probably not as bad as others make it

 

My C63 and CBS both are rattle free.

My CLS550 started developing a rattle in the dash. First MB with a rattle.

 

The stiff suspension probably doesn't help, but it's sad that even the CBS rattles. MB wanted it to keep some of its c class heritage, I guess...

 

Just yesterday I noticed a rattle coming from the back. I will check 3rd brake light first.....thanx for the info above!

 

I think the updated interior is worse for rattles than per-2012 cars. It is enough of N annoyance to make one think about other brands sometimes. Every car can make noise but this is extreme. Luckily, my dealer has fixed mine.

 

I have very minor little jiggles coming from the doors, they seam to get worse after I do some hard cornering, I feel as if the cornering forces loosen up the body. My major problem is the sunroof. It pops very very loudly almost every time I drive on an inclined driveway side ways. It sounds as if someone threw a rock at the glass. This car does not have a very rigid chassis. I'm thinking about getting strut tower braces to stiffen things up.

 

I'm shocked to hear this. "Shocked" makes me sound like a Mrs Featherbottom or something, but that's really surprising.

I've never owned a Mercedes but am seriously looking at a C63BS. Part of the reason is that I have a 7 year old M3 modded to the hilt and I'm turning 40 and I just want something a little more gentleman like. The M3 is loud, but it doesn't have any rattles. Rattles drive me mad.

Is Mercedes really known for having more rattles than BMW or Audi?

 

IMO it's luck of the draw. I've had BMW's that rattled too, and my CLS is the first MB to have a rattle after owning 9 or 10 MB's.

 

C63 - no rattles
E550 - even quieter
GL450 - some rattles (probably toys in the third row - lol)
CLK350 - no rattles

 

It seems to be more prevalent on the 2012+ models. Luckily, 6000 miles on my 2012 C63 sedan, and no rattles. I'm keeping my fingers crossed.

 

6 months in and about 5K miles and no rattles here. Small rattle from the exhaust but a quick tightening of the a brace fixed that.

 

My 2012 is closing in on 11K and no rattles...my old 2010 was a different story!

 

just wondering how you fix and remove the brake light on your car?

 

welcome to the club

in all seriousness is definitely sucks and I completely agree with you... it's ridiculous that our cars rattle and squeak
