Have a 2016 Glc300 with under 5,000 miles and the brakes squeal in reverse. The dealership refused to attempt repairs as they were told by mbusa that the company is aware of the problem and the engineers are looking for a fix. Same was told to me by mbusa customer service. Ridiculous to pay this much for a car that has a known problem with no resolution in sight. They claim it is not a safety issue but will not provide it in writing at the dealership.

The brakes have a loud piercing screech when brakes are applied. It started out as an occasional noise and now it is constant. I have contacted mb customer service as well as the dealership where I purchased my vehicle. All admit that mb is aware of the issue but have no fix or solution. It is well documented with several complaints on all of mb social media sites. I am being told this is not a safety issue and the vehicle is " safe " to drive but this is unacceptable and I am afraid to drive my vehicle now especially traveling on the freeway because my brakes scream whenever they are applied.

Screeching brakes when car is put in reverse. Typically occurs in cold weather. Mercedes said they are aware of the issue but no fix is available. Mercedes says occurs when vehicle has approximately 20K miles on them.

Brakes have gone from squeaking to deafening squeal and do not seem to stop as quickly. Very spongy. Dealer says they wont have replacement parts for months. Concerned we shouldnt be driving the car and dont trust the dealer to be truthful

I purchased a brand new 2016 Mercedes Benz Glc300 in December of 2015. Over the past 6 months, the vehicle has begun making a terrible screeching noise when I lightly press the brakes while in reverse. The noise has gotten so loud and painful to the ear that I reflexively take my foot of the brakes causing me to roll backwards faster than necessary. I recently took the vehicle in for its 10,000 mile service during which I indicated that the car was making a "screeching" noise while in reverse with the brakes applied lightly ("feathering"). I was told by the service technician that Mercedes was aware of the issue and will issue guidance soon. I was given my vehicle back with no temporary solution whatsoever. Since owning the vehicle (about a year with 10,000 miles), I have received no communication from Mercedes about the issue although they have been aware of the "screeching noise" for quite some time. I would like to note that the screeching noise is getting so bad that it is truly painful to anyone inside the vehicle (almost as if I had no brake pads!). I called Mercedes today and they again told me that they are aware of the issue. I asked the rep to note my complaint and issue me an email confirming my complaint for my records - he refused. Apparently Mercedes does not provide email confirmation of complaints to customers who have issues in order for the information "to not go public." Please someone at NHTSA - look into this. They need to be held accountable. Thank you so much for your time!

Brakes started to squeal when backing up at slow speeds. This progressively got worse over a couple of months, until it is now extremely loud. It seems to be worse when it is cold. 3 Mercedes-Benz dealers have all said it is a known issue and to standby for a permanent fix. Started at about 5,000 miles on car, now have about 6500.
