C43 Squeaking over bumps
Hi all,
I've had this ongoing issue with my 2017 C43 sedan, and I am seeking any advice I can get. Especially during colder weather, the car squeaks every single time I go over a bump (Please see the attached video to hear the squeak I am referring to). I was convinced it was a suspension issue, so I opened my hood and would push the car up and down to try to find the source of the noise. Once I did that, I was convinced I heard the noise coming from the strut mounts. I went ahead and ordered brand new strut mounts and installed them, but to no avail, the noise was still there. I was so fed up with this annoying noise; it literally makes the car almost undrivable, so I went ahead and took it a step further and purchased brand new front struts, left and right. After having the new strut mounts installed, I went ahead and installed the brand new front struts, and my process of thinking was, okay, if the strut mounts aren't the issue, it must be the struts themselves. I drove home and did not hear any noise; that is, until I approached a school bump and heard the same exact noise that was bothering my soul. The brand new strut mounts and struts did not fix anything, and at this time I have 0 clue what the issue could be. Any and all help is much appreciated.

I have the same creaking occasionally on my C63, but not nearly as bad as yours. For me it only happens if I drive up a driveway or so on an angle at low speeds. It doesn't get very cold here, and it has gone away the last few days I drove it. I also thought it must be the suspension, but as I was just doing research it might actually be the pano roof. Known issue. Mine was lubricated a couple of years ago when I was complaining about creaks and it may be time again. For me the creaking is coming from behind me around the seat area, but I didn't think it could come from above. At first I thought it was the seat itself. I'm monitoring it and see if I can track it down, but you might be looking in the wrong place as well. It's easy to check. Open your sun/pano roof and if the noise is gone then you know what is causing it.

Thing is, I dont have a pano roof. From what I hear, the squeaking comes directly from the front dashboard area where the windshield meets the dash. I definitely am looking in the wrong place, and after blowing a nice amount of money, I don't even know where to look anymore. Worth to mention, the car has done well over 25k miles on New York roads which are catastrophic to say the least. Thanks for the insight regardless man.

Dashboard creaks are also a known issue in this generation. I had a broken clip in the driver side A-pillar and they also put some felt in known areas of the dashboard that creak. Those are mostly gone. Occasionally when it's cold I still get a little bit of creaking from the dashboard but it goes away once the interior has warmed up. Unfortunately, some of this comes with the territory of a firm car, but yours is pretty bad and would annoy me, too.

As far as the dashboard goes, I always was suspicious of it. However I think that the squeak is far too pronounced for it to be the dashboard, and there's been instances where I have heard the noise during warm weather too. The cold just multiplies the noise tenfold.

it's coming from your control arms, i believe the lowers iirc. i had the exact same issue.
it became much worse in the cold.
more specifically the ball joint. if you look closely there won't be any tears or leaks in the boot, but these get dried up over time.
when i had them inspected there was no signs of play or wear. my indy mechanic just lubricated them with some grease in a syringe, the noise went away after a couple of days of driving. (needs time to work its way around/into the joint)
hope this helps!

Do u have burmester stereo?
should be loud enough to cover up that sound!
sorry
that is annoying and would drive me crazy too!
Does sound like the dash is loose( it’s prob not)
hopefully it’s the ball joint issue and can be fixed.
Did u buy the car new?

I agree with tgidave. Lower ***** on the control arm are known to make noise once the factory bushing wears out. I added grease to mine with a needle and it stopped the noise for about a year. worse when cold, ill replace when i swap out struts and everything eventually.

I also ran into some squeaking issues (not as bad as yours) especially when it was cold out going over anything but smooth glass-like pavement. Before replacing anything as mechanical as control arms, etc, I would suggest having the door seals looked at. I had my dealer look at it and that was the sole cause of mine. They replaced the driver's-side front, and right rear door seals and it instantly fixed the issue.
Then again, I did have a control arm replaced on a 2015 C300 for the same issue so that could definitely be the problem. Just thought I'd share the part about the door seals as another thing to look at before dropping $$ on the control arm.

c43 left side wheel squeaking
Hi Guys, Noticed same issue on mine the other day took it garage could not see any damage or play in suspension or ball joints. tried to inject some silicone wd 40 with a very thin pharmaceutical needle in a couple of ball joints but no luck. I read on another thread to wash the whole wheel out side and inside with a hose which I did and guess what sounds gone completely 😅 no squeaking when turning or driving think it may have been some grit stuck behind the brake disc plate. been dry weather for a couple of days and no sound what soever

I have had this same exact problem for 18 months, but mine sounds worse in the summer verses the winter. I paid to have my strut mounts and struts replaced and it didn’t fix it. I then took it to MB and they told me it was the upper control arms. I was going to change them in a couple months, but after reading this I will try adding grease to the ball joints and boots first. I do have 85,000 miles on my car, but that isn’t a ton. It’s embarrassing driving the car with this loud annoying sound. Hopefully this fixes it!

I definitely hear the noise coming from under my front dash though. It is the weirdest and most annoying sound. I’ll try the grease today since I have the tires off for a brake and rotor change. If that doesn’t work then I’ll consider the sunroof or swap out the upper control arms.

It’s not the roof. The squeak is very much coming from under the dash. If everyone on this thread made a claim here below, we might get them to look at it. This sounds like a huge issue across the board. My driver side seatbelt doesn’t retract either and they say my VIN doesn’t fall within the recall. BS!
