Also when you go to your dealer, they might insist on cleaning and sanding the brakes. This will only fix the problem temporarily and it will come back later. When you bring the service bulletin with you, tell them that you already tried to clean the brakes and that it only delays the problem. I have researched this problem alot and the only fix that works includes them replacing something(brake pads, brake lingings, caliphers,). Usually they replace all these things togther, just make sure you look at your service receipt to see what they replaced or otherwise did.
