“I purchased the car in may 2016. By august 2016 the brakes starting squealing very loudly when backing out of garage, parking spot, etc. I took the car to the mercedes dealership in november 2016 and was told they are aware of the problem but there is not fix. I am afraid to use the brakes when I back up because of the hurtful noise. There must at least be a temporary fix?”
NHTSA complaint #10947362, filed 2017-01, 3,000 miles“I have a very loud screeching sound when I take reverse. I reported this issue when I took the car for the first service. I was told it was fixed but it came back within a week. Though I own a new car feels embarrassing when I reverse out of my garage when the whole neighborhood could hear the screeching noise.”
NHTSA complaint #10981302, filed 2017-04, 16,000 miles“Brakes started screeching loudly when backing up startling neighbors. After seeing many reports on this same problem, I had the dealership replace the brake pads as goodwill. Screeching returned shortly thereafter and I continue to annoy neighbors. Runflat tires threads were worn out after only 10,000 requiring replacement of all 4 tires. Rear door driver's side is unable to be unlocked or opened from the inside. Driver's seat side panel covering seat belt continues to fall off exposing the seat belt drive, even after repair by dealership.”
NHTSA complaint #11096506, filed 2018-05, 10,000 miles“Mercedes benz GLC300 brakes began to squeal soon after purchase. This was noticed when backing up after vehicle sat for a while, rotors and pads cool. Reported to dealer, but they did not seem concerned or mention any known problem related to glc 300 brake noise. I did not press the issue at the time as I thought it might go away after the pads were broken in. Unfortunately the problem has gotten progressively worse. Now it even squeals when going forward if you lightly apply the brakes, again this is when the pads are cool. …”
NHTSA complaint #11044333, filed 2017-11, 2,000 miles“Leased the car with 4,000 miles on it (it was a loaner) and after driving it for a couple of weeks the brakes started to squeal when backing up. Called service and I was told this was normal because of the humidity in the air. Dealt with it for another couple of weeks and called service again. This time I was told there was a problem with the brake pads and they were waiting to get them from germany but it was not a safety issue . I'm very upset that they knew all about this when I leased the car in september 2016 and never said a word about it. …”
