Hi everyone, I have a 2024 Mercedes G550, and I have been hearing a strange buzzing noise (with slight vibration) coming from behind the steering wheel—or possibly from the steering column. This noise started right after my first service, which included an oil change at the dealership. I clearly remember hearing that noise when I was about to park my car at a low speed/rpms after I picked up my car from the dealership. Never have I ever heard this noise before.

The sound only happens when the engine is around 1500 RPM (It almost certain and only happens at 1500 rpms, the noise is gone once it passes 1500 rpms), regardless of vehicle speed. It does not seem to occur at other RPMs as I tried to keep it around 1500 rpms and the sound was evident and remained consistent until it passes 1500 rpms. I also tried to rev it to 1500 rpms when the car is in park, it does not seem to happen.

I suspect it might be due to something was not properly reinstalled or tightened during service. It feels like something is vibrating or resonating at that specific engine speed. Has anyone experienced something similar? I would appreciate any insights—especially if this could be related to something that happened during the oil change or service process. Thanks in advance for your help.

I took it to the dealership for inspection yesterday and they told me two technicians drove it multiple times and they did not hear anything.

I also captured a few videos when the noise was happening. For video 1, it starts at 2th second. For video 3, the noise is heard at 1st second. Please kindly let me know if you need more information or longer video regarding this noise. Thank you again for your help!

 

Here is the 1st video I just uploaded it

 

Here is the link for video 2 and the nosie starts from the very beginning all the way to the 3rd second, .
Here is the link for video 3 and the noise starts at around 1st second and after,

 

Where there any recalls performed?

 

Well, I do not think there is a recall on this issue as it is probably an individual case. The noise just happend and remained consistent after my 1st service.

 

Well, there is no factory recall on this, as it is an individual case. The dealer said that they could not verify the problem....

 

Well, there is no factory recall on this issue. It is more of an individual case.

 

I see, hopefully someone else chimes in.

 

With any individual sound/noise problem a car has the dealer/service dep't will ALWAYS get back to you with the we cannot "replicate the issue" card. Be it Mercedes, Ferrari or any other brand. I don't know why, but can only think it's because they're lazy and it's highly lucrative. Did you know they charge the manufacturer a fee even when they can't "replicate the issue" if the vehicle is under warranty? They oftentimes allege/claim with the manufacturer they spent hours trying to identify the source of the problem but was unable to (while in reality they did little or next to nothing), which is a windfall for the service dep't since they get paid by the hour for manpower by the manufacturer. I learned that long ago from my Dad, who is an avid collector of autos.

I recently had an issue with a noise coming from the driver's side window on my G63 went over uneven roads. It was annoying as heck as it was right next to my ear, but it only happened in S+ mode on certain roads. Knowing how service dep't works, I told my advisor the moment I got there that I don't want to hear the words of they cannot "replicate the issue". I made the advisor go with me while I drove so that he could acknowledge there is a noise/issue. They were then able to identify and fix the noise/issue so now my G63 perfect (again). I even started a thread about it.

I would suggest you do the same. Take your G back in and make the service adviser drive with you until he concedes that he does hear a noise. Otherwise, it will be a game of attrition for months before you just give up while the service dept gets paid thousands by MB for doing nothing.

 

Thanks for chiming in, all good advices for OP.

 

I went through over a year of crazy squeakings, clunks, creaks, and whatever the noise you can think of with my Alfa 4C before my dad stepped in and rescued me from hell by teaching me how to handle service reps in these scenarios. I'm highly acoustically sensitive or intolerant (started on piano at 3 years old, for which I blame) and I hear everything, for better or worse. Now my Alfa has nothing but engine and exhaust acoustics when I drive it. I know I may be overly sensitive to sounds, but unwarranted acoustics in my cars can drive me to the point that they kept me awake at night in trying to identify the source.

 

Thank you for your support and for sharing. I guess we probably went to the same dealership based on your profile. For some reason, I had a bad experience going into that dealership last week. Judging by my appearance and ethnicity (I am not locally from the States), the advisor told me that "they did not do anythign that caused this noise except for oil change, do not accuse us of doing that". The fact is that I am 100% sure it was them who caused the noise because I never heard that noise before sending the vehicle in.

The advisor told me that it will take longer if it is noise/ sound related, I will need to leave the car there from Friday to Tueday. However, the technician and the shopforeman test drove it 3 times and they were unable to replicate the noise. My advisor called me the same day to pick up my car and come back again. I do not understand why I had to pick up my car and revisit. They just did not want to do it.....

 

I am just a bit hesitant and worried that they would remove a lot of parts, which could inevitably cause many other problems or noises based on my previous experiences with my amg gle63s. They tried to change the oil for me and fix my rear door panel. For some reason, there was a weird clicking sound coming from behind the infotainment system after picking up my car. They also kind of pulled on my rear door while working on the panel, afterwards I realized that that particular door sticks out a little bit than the other one...

 

Very nice, always like DIY stuff and we appreciate you shairng your knowledge with us!

 

Sorry about your experiences at the dealership. It's likely that we do have the same one if you base it on my profile. I've never had an issue with their service dep't - other than the typical gawking and stuff that male mechanics do with young female customers... Nevertheless, I'm accustomed to it and use it to my advantage at this location. Did you purchase your vehicle at this dealership or at another dealership but are just having it serviced in BH? I've written in other threads how in SoCal - especially in BH - MB service dep't treats vehicles purchased elsewhere completely differently than those purchased at its sales dep't. Since I purchased mine there, I always receive a nice rental and they bump me up in line ahead of everyone else when I arrive for my appt so I can avoid the standard 45 min-1 hr wait. It's not because I'm special, but they tell you at the sales dep't when you purchase an AMG from them. For what it's worth, neither my Dad (who owns 8 MBs) nor me had ever had service-and-return on the same day. After all, that location is the busiest in all of North America. I'm truly sorry if you think your experience is based on your ethnicity. It's ridiculous in this day and age you should be made to feel that way, especially in SoCal of all places. Decency in our country is not going in the correct direction...

With these guys, don't be hesitant. The noises will drive you insane down the road. Just be more assertive when you bring it back. Don't leave your vehicle there unless/until your service advisor goes on a ride with you and acknowledges the noise so they can stop with the "we cannot replicate the sound" BS. The onus would then be on them to solve the problem(s). Stand firm and good luck! Let us know how everything turns out.

 

Best of luck with OP, I guess if this dealership isn't willing to help, try another one.

 

Following up with you OP, any chance they fixed it for you yet?

 

And I thought I was the only one...Noises like you describe drive me insane

 

noise issues are one of the most annoying ones ngl.
