Gle 350 de crunch when braking

[tartanblueradio]

Hi All, I’ve just bought a 2022 gle 350 de hybrid. seems great except one issue, as soon as we drove it away from the dealership post test drive, it started making a crunching/creaking sound when braking, almost feels and sounds like something metal engaging or disengaging, you can feel it through the brake pedal too, certainly doesn’t sound healthy. Dealership has taken a quick look and said the brakes look fine which doesn’t inspire any confidence. This happens about half the time I brake and very consistently when slowing from 25 to 15 mph. I have 22 videos of it happening which took me only an hour to put together, I’ve shared with them so it is now still with them for further investigation. I’m still within the return period but would much rather it was fixed so I can keep it. Anyone got any ideas what it could be? See below for a video including sound

Surely that's not normal?

It's not ABS or regen that frequently.
You'll need to go out with one of the 'technicians' in the car with you I'd suspect

Not normal indeed! Good shout, that may be what’s needed to prove it
