I've had the same issue, mentioned it many times to service, but they say brakes are fine. "Unable to reproduce". Since, i first got the car.

It's louder during winter. I have to spray windshield wiper fluid on my brakes to leave my house without squeaking.

Now i am closer to needing new brakes, we will see.

Same. I would gladly pay that to not have my car squeaking at lights, if they could guarantee that.

It is actually pretty common for the W205 brakes to squeak, your issue is not unheard of, sometimes bedding them in helps. Your dealership said the rotors doesn't seem OEM and the pads aren't either? What is the thickness left of the pads and rotors?

The rotors are OEM but a bit warped and the pads aren't OEM and are of low quality, according to the dealer the pads still have some kilometres (approx <7k) on them so they can be replaced.

My car also does that, but it is definitely not as severe. I have genuine Mercedes pads and rotors.

Ya it is a common issue or... characteristic of these cars if you think of it that way it might make you feel better.

"Characteristic of the car" aka dealership's favorite phrase to not fix things on your car

no luck here, replaced a couple of times still squeak either next month or the season following, it always came back. I thought I got a mouse hiding in there when it was so loud.

They want us to buy a Brand New Benz to fix the squealing brakes.

My old W204 never ever had this issue.

A 60k+ car that squeals in reverse, at the light and in the drive through. (and call it normal?)

Am thinking that's another reason they added acoustic glass, so you can't hear the other cars laughing at you.

Ah but it is "not normal" for any other car, but it is a "characteristic" of the W205
