Good luck with that!

I just ordered a loaded GLC300 a few days ago, but just read all NINETEEN pages of this thread. GEEZE! This is just crazy that this problem has been unsolved for what is becoming YEARS now. I think I’m going to cancel the order. I’m a big MB fan (we currently have three), but I’m also one who is highly disturbed by noises, especially the type of noise associated with squeaky brakes. It is truly amazing, when you think of the experience M.B. has in building vehicles, that something like this still happens. And then, for them to not, IMMEDIATELY come up with a PERFECT, solid fix for the problem, when we KNOW that they can. It’s pretty depressing. Good luck to all you folks who are still suffering with this. What a mess.

I can understand the frustration with this issue. But really, do you believe MB can come up with a solution quickly? I would think they would want a fix ASAP. They know this isn't helping sales nor the brand.. why wouldn't they try to get a fix in ASAP? FWIW, I've had mine redone in the summer and the sqeak is back.. though less. Strange since it took some miles for it to show initially yet it returned pretty quickly (i.e, not 7k miles )

I admit to my patience wearing thin while waiting for a call from Mercedes informing me that another version of replacement brake pads has arrived. I agree that Mercedes, more than anyone, wants to see this problem go away ASAP. And so did Audi who took 4 yrs to solve exactly the same problem on some of its A and Q models. BMW, VW, (and, yes, even) Porsche had or are having their turns as well. It’s definitely not unique to the GLC, but it seems to be a uniquely German brake thing.

Last week new front pads (latest version) were installed on my GLC – now quiet as a church mouse. Fingers crossed.

My 2018 GLC300W4 breaks started squealing about a week ago in the extreme cold weather. Had the car 10 weeks and have 2200 miles on it. Set up appointment with dealer for 1/3 and intend just to ask them to replace the pads and the lubricant rather than going through the exercise of "let us keep us overnight and see if we can replicate it." It is a well-known issue and I'm certain they have seen it before. Will post my results....

Waiting for vehicle now. Service Advisor says that the brake pads are a known issue and that MB has sent them the newly-designed part. They are just replacing them on customer demand

Quick question for the GLC community on the screeching brakes; Does this affect the GLC43 AMG model at all? Haven't seen anyone address this here. I ordered the 43 model and want to know what to expect.
Any helpful insight into this is very much appreciated!

Just spoke with my dealer on the phone. Again, I complained of the noise. She said, a lot of customers are complaining about it. She said they received a bulletin from Mercedes, which said parts to fix this will not be available until 2019, yes 2019.

I said it was unacceptable.Essentially said too bad, call Mercedes Corporate.

I said why do I have to call Mercedes. Aren't you the dealer, shouldn't you go to bat for me. She is going to speak with the service manager.

nsoltz: Do you have any information about this "newly designed part," that my dealer knows nothing about?

NOT Happy with Mercedes right now.

wow. that is unbelievable. they must be redesigning the entire underside of the vehicle.
so based on my experience i guess every 4k miles or i go into get new pads to keep the noise down until they get me an updated part.

AverageGuy

They told me they wouldn't even put new brake pads. On the initial call, they told me they will do NOTHING. I'm still waiting for a call back. We shall see.

Had my front and rear pads replaced. I have not had the noise return. It seems every dealer has a different story about whether there is a fix or not.

romeodeng007

Drove the car for almost 1 and half years, have the front/rear breaks replaced twice. I feel there is no update for the breaks, they just replace the breaks every time until the noise comes back. I am glad I chose to lease this car instead of own it.

ajmtbm

how many miles since replacement? are you in a cold climate?

dieseldoc

It has been 4000 miles. Live in DFW. Temp has been recently in 20s at night 40s day. No noise. It had noise before replacement with similar temps.

ajmtbm

Question I have is how often will they replace. If every 3k miles I get a loaner for a day and get new brakes and a free car wash that's not the worst thing in the world.

Jetfuture

Not all dealers are doing that. Some are being "difficult" and others claim they cannot get the parts for 6 months. My dealer has been fairly responsive.

ajmtbm

Wow. How many miles and did they just replace the pads each time? Front or rear or both?

Tell them you would like an appointment with the zone manager to discuss the issue.

Please read all: Got my 2018 GLC 3 months ago and it has 2400 miles. I too have the brake squeal in reverse but also happened in forward yesterday when it was 15 degrees out. I took it in today for that issue as well as 3 others. The second issue is the vibrating steering wheel when going over 55 mph over seams and small bumps in the road. Third issue is my radio is not working. I get "Device Unavailable" when I choose radio. The media(usb stick) and cd/dvd work fine. Last issue is misaligned chrome trim on both passenger side doors. If you look at the top of the doors just above the door handles there is chrome trim that runs the length of the doors. When the doors are closed the trim on each door is higher then the mating part. They are perfect on the driver side. Will someone please check and see if this is an issue on your car? It really looks sloppy and not like a luxury car. Does anyone else have the steering or radio issue? Or a solution? Thanks.
P.S. Also have the shuddering wiper issue but decided not to bring that one up at this point as they seem to be smoothing out with use but they were brutally bad early on.

No screeching brakes yet (only have about 1,200 miles) and no vibrating steering wheel or radio issue. Also our GLC does not have any chrome trim on the doors. I wonder if the dealer installed them.

I have a 2018 GLC43 with 2100km (1300 mi), no brake issues or any other issues - even though it has been -20oC recently. It has performed perfectly. I know that the others have reported that squealing brakes starts with more miles but so far this is a great vehicle!
