When I was pulling into a parking spot at a low speed, the car accelerated and lurched forward, hitting a wall, which deployed the airbags. When the car started to accelerate, I hit the brakes but they did not engage.

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 squeal very loud and I am constantly having to brake hard several times to make this noise temporarily go away. I have taken it to Mercedes and they say that this is not under warranty. I took the SUV once early on after the car was purchased. The dealer told me to brake hard a few times and this would go away. It didn't I took the car three times to the dealer until finally they replaced the rear brake pads but tried to charge me for it. The brakes continued to squeal. I took it to and independent garage to have the pads replaced at my own expense since Mercedes doesn't know how to fix the problem. Now the brakes are still squealing and are very annoying. If I do not get this fixed, I'll never buy another Mercedes. This only happens when moving and brakes are usually cold but sometimes it squeals regardless if it is cold or not. Very annoying problem.

Breaks continually squeak in reverse on colder mornings at slow speeds. Even if the car warms up for several minutes, the loud squeaking does not stop.

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.
