My wife says it sounds like I have a POS car. Seriously, it's embarrassing. I've had AMG's and Porsches and none of them gave me this issue.

Has anyone actually had BMW fix this issue? Or are they still hiding behind the "this is normal" BS line....until we magically get aftermarket pads and the issue goes away immediately.

My M550i didn't have this issue, either (not the same brakes but still upgraded brakes versus normal G30 models).

do a search plenty of brake squeal threads already


.....The loud brake squeal noise and crazy black brake dust is due to the cheap oem pads they use.........I had the issues and fixed it by replacing the pads with Porterfields r4s street pads (ACG pads are made by Porterfield)...just call them and order direct.....now I have zero squeal and ~50% less dust
