Sitting in MB garage and have just been told yet again that the SERIOUS BRAKE SQUEAL on my 2017 GLC is not covered under warranty. I even showed them a video of how bad it is and quoted all the info and part numbers listed above but they are having none of it. They want over 拢450 to replace the front and rear pads. 馃槺
no this is not right, they have a serious problem with this car

My wife also bought this car in 2016 and had it serviced 4 times in the last year to try to attempt to fix these breaks. The latest response this last week was that the pads were replaced (again), lubricated and supposedly followed a "new" set in procedure. As a side note, whatever this set in procedure entails, it involved driving our car almost 30 miles during its last service. Has anyone come across any real documentation or response from Mercedes on this issue? How can they continue to keep selling these cars. If we knew this potential we would have never purchased the GLC.
This is so ridiculous that they can not fix this. I have the exact problem.

I have terrible issues when putting my 2019-GLC 300 in reverse. The squeak can last for up to 20 seconds. I have brought the car into Mercedes, have had the brake pads replaced, and 500 miles later, it still does squeaks like crazy. Mercedes says they know about the issue and are aware of it. That really helps me a lot. Had I known about this prior or had someone advised me when I purchased the car, I would never have bought it.
I would never of purchased the car as well and I will let everyone I know about this and how Mercedes treats you. This is not right, that is exactly what my car is doing.

We are having the same issue with brake sound. We took it for a fix and it seemed to go away for few weeks and again its making the sound. It is so embarrassing every time taking it out in the neighbourhood, literally everyone can hear us go out, so annoyinggggg. The dealer says to drive the car FAST and put a SUDDEN BRAKE, seriously??? I have a child in the car, why should we have to drive rash for their mistakes?
I am with you on this, how annoying and same thing, people always look at me when I put it in reverse in my neighborhood.

* UPDATE *
So, I brought my 2017 GLC300 to the dealership today after experiencing loud squealing brake noise and I have 2 things to share:

(1) They explained that MB brakes are designed to be used with moderate to heavy braking pressure, and there can be a transfer layer from the pads to the rotors that needs to be worn off with regular braking, otherwise some squealing noise can result. Also, this can be more noticeable in colder weather, which is what we experience here in Toronto.

(2) They still agreed to examine the brakes and ended up replacing all 4 pads and associated brake liners (in the brake shoes). What's interesting is that in the invoice, they printed the fact that this GLC300 brake squeal had MB technician tips #L142.10-P-064944 and #L142.10-P-065927 associated with the recommended repair to replace brake pads and liners. Even if this is an internal technician blog for tip sharing, or if this an official MB release, it tells us that this is a known issue with some type of corrective action.

No more squeal, but time will tell, especially as the weather gets colder, and dry again.
THIS SQUEALING IS A COMMON ISSUE

Trillende remmen bij koud en nat

Hoi,
even kijken of iemand op de plug-in hybride GLC 350e een trillende of trillende rem heeft ervaren, vooral tijdens de eerste 1-2 keer remmen bij lage snelheid als de auto nog koud en/of nat is? Ik heb de remmen laten nakijken bij de dealer, maar die vonden niets aan de hand. Mijn auto heeft sinds nieuw (mei 2017) slechts 16000 km op de teller. Maar dit schudden van de remmen is het grootste deel van die tijd aanwezig geweest. Ik vermoed dat dit probleem iets te maken heeft met de overgang tussen regeneratief remmen en regulier hydraulisch remmen. Ik begrijp dat de auto is geprogrammeerd om het remsysteem te testen tijdens de eerste 1-2 keer remmen, elke keer dat hij start. Eventuele opmerkingen?
[/CITAAT]
Ik heb hetzelfde probleem auto trilt tijdens remmen lage snelheid vooral bij 1 en 2 keer remmen.

Ik heb de auto naar de garage gebracht, ze hebben niets abnormaals gevonden, maar het probleem is altijd aanwezig!

Is het probleem voor je opgelost?
