Lucky! I tried to get things improved during my last service but my service dept didn't offer to do anything other than let me buy new pads/rotors.

I am sorry for you all squeak-victims !! I am another one too!!
on perfect discs new pads keep squeaking,
tried ALL ways to fix, dismounted three times!
at he end I realize it is due to the material of the pads.
I can only say: avoid SIMER and XPAD brand pads like hell !!!!!!!

Reviving an old thread here just to document the prevalence of brake squeal - It is driving me nuts - I need to get this thing in and repaired before the weather gets nice or I'm gonna be pissed.
Those that have had the dealer remedy the issue - is there a TSB # I should reference?

First: if everything is clean and okay, squealing depends on pads. Personally I solved changing pads and installing EBC Ultimax pads (http://www.ebcbrakeshop.co.uk/)
Then if brakes are single piston models, apply a copper paste lubricant on every part that slides (except disk surface
DDD )
Second: apply "anti squeal brake shims" (eg. ebay) on pads. If squealing s dramatic, this tip comes from EBC technical service, install shims only on half of the pad so it covers half of the piston area; (since squealing is a resonance phenomenon, all that dampens pads or changes their geometry will hopefully stop resonance).
I searched a lot regarding restoring resurfacing brake disks, but seems that there is no influence on squealing.

Mine squeak to, just came back from the dealer and he said the bads are fine, not worn.
Great, that helps.
Of course they're not worn, it's a new car.
So no help from the dealer, I guess you can't expect more for $125000.

I've discussed the issue with the brake buyer in Germany responsible for the BR231 and they noted there hasn't been any discussion with the supplier on updating the compound as the pads currently meet engineering specs related to performance requirements.
I'm sure if enough noise (no pun intended) is made there will be a change later on

Pads replaced
My wife's SL550 had that problem. It was quite loud. When I drove it into the portal at the dealership they could hear the brakes squealing.
It took two visits but they replaced the pads. It's a common problem with high performance pads.
I have a brake squeak on my 2014 Viper TA but not bad enough to have it fixed.
