“When braking, the brakes make a grinding noise. This happens any time you apply the brakes when I am backing out of the garage of my home and when I stop at stop signs and stop lights and when traffic is at a stand still on the main thoroughfare. The noise will eventually cease depending on how often the brakes are applied. This is an ongoing issue that started in august, 2018 and continues as of february 10, 2019.”

The brakes continued to squeal. …”
NHTSA complaint #11157119, filed 2018-12, 2,500 miles“I am having an issue of squeaky brake. It usually happens in snowing day or day after from front wheel. But, it would have happened at sunny day too. It sounds very loud, so annoying. I took my car mercedes dealership where I leased the car. For the first time, they fixed. According to the invoice, the technician found and confirmed the issue of squeaky comes from rear wheel. But, it happens now at front. It is pretty much doubtful about whether they did good job or not. I attach a link of youtube which I recorded the issue my self. Please volume-up and watch the video. …”
