purchased a C Class 200 with 42,000 miles which had 8,000 miles still left on original warranty then I turned around and purchased a two year extended warranty, I am hearing problems to the bearing and front passenger brake is this service covered

Call the dealership, make an appointment, discuss these with your advisor. Brakes are wear and tear items, so I doubt that will be covered. There are many bearings, in/attached to the motor/all over the car, being specific is key, but those are also wear items.

Yes. Bring it in to any MB service center and they can help you.

Yeah. I believe so.give them a call
