Hi, I bought a GLC250 in February 2016, have run a total of just over 18,000km up to today. The brake squeal in reverse issue started happening a few months after I bought the car but MB service failed to fix the problem after three attempts. This problem persisted after they had replaced the brake pad, add brake paste etc. In fact, the squealing is getting worse not better. I also experienced the vibrating steering wheel problem in 2017. They said they would replace the tyres for me, saying that these new tyres will be more suited to the Australian environment here. I am still waiting for the tyres to arrive today after a long wait of more than 3 months. Just before the 2018 new year, we got the message on the dashboard that the brake pad needed to be replaced, and this was after a mileage of just over 10,000km. The radio also started to play up that we could not hear anything. I brought the car to the dealership today. They told me over and over again that it was by design that the brake gave this squealing noise, just like any new modern fast cars and refused to admit it was a problem at all. He said because the brake was so powerful and most of my driving is city driving, so the brake pad will wear out much sooner than what I had experienced or expected. He also said the radio issue was because the digital signals are weak in Sydney, rather than a problem of the car itself until I showed him the problem while we were both in the car. It was clear from the display that the car did receive the digital signals but there was just zero volume. He said he will look into this for us. All in all, I agree with all your comments above that GLC is a very poorly built car with many inherent problems which seem to pop up from very early stage. I couldn't imagine what else might come up as we run the car for more years. This really damages MB's well established reputation. MB has done really well in the last decade in Australia and probably around the world. I can't help but have the feeling that they have sacrificed their emphasis on quality while chasing the volume if looking at MB from the GLC perspective. I am now hesitant to recommend others to buy MB, let alone the GLC.
