Delivered my GLC to the dealer this morning for noisy brakes.
Not expecting a fix, only that, "sorry Mr. Myers we have brake pads ordered but they are on back order with no firm delivery date. We'll call when they arrive."
These same brake pads, for another client, have been on back order since December.

New Jersey Dealer
Hi Guys hollab:
I'm new here and also have the same problem; yesterday was a snow day here in new jersey and the car made horrible sounds reverse and forward....
I took my GLC to the dealer today, the manager told me there are a lot of GLCs with the same problem and MB in Germany is testing the new brake pads... he advised me to call mid March to see if they have the new parts but that was it.
. i love my car but the sound is embarrassing; when i take the car out of the drive way in the morning the kids that are waiting for the school bus cover their ears..

I just had my brake pads replaced (front and rear) today for the noise issue. Dealer said they only had 1 set of the updated pads available when I came in.
Obviously I haven't had a chance to try this much, but in case folks are wondering the bulletin and parts numbers written on my receipt are:
FRONT: LI42.10-P-065628. Parts: 000-420-81-00-64 (TS Disk Brak) and 001-989-87-51 (Brake Paste)
REAR: LI42.10-P-065058. Parts: 000-420-83-00-28 (TS Disk Brak) and 001-989-87-51 (Brake Paste)
Lastly, dealer also performed a recall (which I wasn't aware of) on Rear Fuse Relay (campaign #2016110001).

Had my 2016 in for a tire issue last week; asked about the brake squeal issue. New rotors are in parts, waiting on brake pads. I had two recalls done in June and as we know it did not resolve the issue:
* Front: LI 42.10-P-063978
* Rear: LI 42.10-P-065058
There are more recent bulletins that now apply, buried somewhere in this message board/string. But parts are the issue as I have read.
Thanks all for updating us! Maybe by the time summer hits in the northern hemisphere we'll get the parts (and then we won't have the symptom!).
"So it goes."

2. Paying $45,000 to $65,000 for a car that has a known defect is unacceptable to a reasonable person.
3. "Squeaky" is not a good description. Squeaky would be the sound that two pieces of plastic inside your car make when vibrating in contact. I call this a loud squeal. Apparently you haven't seen the videos out there on this. In my neighborhood, my daughter can hear the squeal from 2 blocks away at the bus stop.
4. It annoys the neighbors when I leave for work at 6am. It's loud enough that, yes, you can hear it inside homes.
5. It is embarrassing to back in reverse. We have modified our behavior when parking the car, so that we don't have to reverse as much with the car.
6. Mercedes-Benz's motto is "The best or nothing". These brakes are not that. And their treatment of customers (lack of an apologetic letter, lack of any letter, lack of contact with model owners) is poor.
7. News companies have started giving this coverage because it is a chronic issue.
8. As long as it's a known issue, the resale value of the car is less (owner is losing money).
But you are right...nothing to see here...it's not really an issue...we should all just live with it.
In the meantime, many of us have contacted attorneys. And many have already settled with Mercedes-Benz.

If they screech all the time that is a definate problem. A screetch the first time when backing up with cold rotors is nothing. Put a set of Padgid's on the and the first few stops make more than a screech 
. My guess is that the pad compound will change slightly with a slight trade off in braking ability. Not inital bite but, ability when they are hot and experiecing multiple high speed stops.

lets just put it this way, my 1995 SL500 has quieter brakes then the brand new GLC300. hell there is a lot of things i like better about my 1995 car. all the new computerized gadgets are nice. ventilated seats, navigation, satellite radio, heads-up display, LED lights. all amazing. but, the car itself, the drive, the quality, the 95' wins it all.

2016 GLC 300 4 MATIC
Hi guys. I just wanted to give you guys an update.
I fixed my 2016 GLC 300 yesterday.
The dealer told me that they have followed all the instructions from the MBUSA with the new parts.
The work they did was to replace the front disk brake pad and the number was
000-420-83-00-28.
However, as soon as I received the car and reversed out of the MB service center, the brake noise was STILL THERE. WHAT THE F....
The service people were shocked and told me that they will open up another new case with this updated bulletin fix.
I gave up on this matter, I am going to sell this vehicle.
Any comments if my part's are incorrectly replaced?

Well... the "new/new" front brake pads that been alerted by bulletin - but have not been released yet - have the same part # - but a added 2-digit suffix....
So... your front brakes were replaced with incorrect partial part# - or your dealer was "trying" to get something done in the hopes it might solve the problem..
Frankly... the new/new MB front pads - correct/full part# is not expected till like June.. I am having my shop "test" Meyle emplacement Semi-Metallic and Meyle Ceramic front brake pads as customer test.... but I won't know results for 3-4 weeks..
Inspected both Meyle pads.. both Meyles have correct plate and molded pad shape ... if I had to "bet" I think the Meyle Semi-Metallic could be the winner.. the Ceramics look too grippy..
Keep the beat !

We had our front brakes replaced in early Jan and are are rear brakes on Friday. Since our front brakes were replaced we have had no squeeking and have been through some really cold weather. Hope this fix lasts.

Not just in cold weather
It got MUCH more pronounced and consistent, though, during the winter....and now that we are transitioning to spring and mornings are warmer, it is happening less frequently.
But I've also noticed that I am starting to get some screeching on braking while driving forward, not just reverse. But it's still only early on when driving.
Looking forward to the fix. I know it's not a safety issue, but this is not what I expect when I pay $54K USD and it's supposed to be "the best or nothing." I really love my GLC, but frankly BMW X3, a redesigned Audi Q5 and even the redesigned VW Tiguan are appealling to me....but the problem/risk there is that you just don't know what issues you get with a brand new model.

Well - our brakes our squeeking again. So, Mercedes has now done three seperate replacements on our GLC. Very disappointing.

3 attempts to fix with no resolution qualifies you under 'lemon law' statutes in many states in the US. Something to consider.
They haven't even gotten around to try the first time with ours yet. We have 2 years total in our state, 1 year down.
