Brakes?
9,800 miles and my dealer is telling me the noise is "normal" for AMG cars, but the pads don't need replacing as of yet. Good luck getting a straight answer out of your dealer!
Reamedy: remove pads + use a bit of sand paper to de-glaze pads
Also build up of brake dust can cause slight squeal when coming to a stop. try clean out with some brake cleaner.
