“Rear braking system. When backing up or applying pressure to the brakes, the vehicle is screaming a loud noise. Taken by dealership at 7000 miles 01/04/18 dealership states they can't fix it until they receive parts ,with the takata recall and a faulty braking system, this is a highway safety issue.”

“Bought car 3 days ago and brakes squeal upon backing out of garage and sometimes applying when stopping! Specifically asked salesman if mercedes had problems with brakes making noise as we went through this with a vw toureg and was told no they do not have this problem. Called salesperson today and was informed now that they are aware of this issue and its normal and should only happen when car has been sitting and its cold or they got wet. Told if it goes more times than that bring into service???? …”

“I purchased a mercedes glc 300 2017 in september in delray beach and when I approached 3500 breaks started to squeal. I took the car in and they said they would order new breaks. This was 2 months ago and nothing has happened yet no fixes and they weren't even aware that many consumers had complained previously. They keep giving me the run around that the parts are coming from germany etc. I bet you if they were trying to sell a car they would have brought that car faster than my breaks. Car is still squealing and waiting for a fix. Mercedes slogan is the best or nothing else ?! Well..... …”
