 This is my first and likely my last MB! I did the research and ultimately decided on the GLC 4MATIC SUV  (BMW X3 , Acura RDX and Audi Q5 were closely considered).  The smooth ride, MB reputation, customer service (boy was I wrong!) and safety record sealed my decision.  At 6 mos. old and only 3K miles on my car, the SCREECHING brakes are SO incredibly loud that I have switched cars with my husband.  The brakes wake my young daughter up from a sound sleep as I am backing out of the garage in the morning.  My neighbors and colleagues have asked multiple times, "What is wrong with your brand new car?"  This is not a small squeak, but a screech that turns peoples heads!  This is evidently a known problem to MB and they have no solution to date.  My car is currently at the dealership for a 'temporary fix', which the service manager admitted will only put a brief bandaid on a larger problem that MB has yet to formally acknowledge to its high paying customers.  No letter from MB.  No phone call.  No email.  Nothing.  Just me calling and complaining, with the dealership ultimately putting me on a waiting list for several weeks to have a temporary fix implemented.  Sorry MB, but this lack of acknowledgement of a problem and disrespect is not going to earn you my loyalty.  How do I know if the car is even safe to drive?  MB - I'm very disappointed.  I've waited a long time to purchase a brand new car that I've worked very hard for.  Potential customers be warned and go with another option IMHO.
