Mercedes-Benz of Valencia

I took my CLK500 in for brake squeeling in December 2008 to MERCEDES BENZ OF VALENCIA. The noise was diagnosed as worn out brake pads in the front. My service technician told me I had to replace both the to MERCEDES BENZ OF VALENCIA. The noise was diagnosed as worn out brake pads in the front. My service technician told me I had to replace both the pads and rotors to eliminate the noise. So I did. Two weeks later, the noise still persisted, and took the car back in. This time I was told the rear brake pads and rotors needed to be replaced. Annoyed that I wasn't told this the first time, and having wasted another day at the dealer, I gave in and replaced them. We're talking pads AND ROTORS. The same day off the lot, I hear the noise again nonstop. Pissed, I return to the dealership the next day and complain. The pads are then dipped in anti-squeel and put back on, and the rep tells me that there should be no noise at all coming from brakes since all are brand new. The car is good for about a month and half, at which point the noise comes back full force, every time i brake day or night. I return to the dealer uncontent. They have a technician sit with me and drive to hear the noise... we don't even make it out of the lot when the technician says "i hear it loud and clear, dont bother leaving the lot". SO my service rep tells me he will replace them. I get a call the next day and my rep says his service foreman tried to duplicate the noise and could not after driving 70 miles with it. I told him "why did you have my ride with a technician who validated the noise, only to tell me otherwise today?" He tells me he will bring it up with his manager. His manager decides that since I wore out the brakes they might be overheating and causing this, and they wont replace. I was very upset, since they are NEW PADS AND ROTORS that Mercedes should cover!!!! I hardly put a few thousand miles on them. Ridiculous!! So i call MB Customer Care and a case manager calls the service manager at Valencia Benz. He concludes that she was in the right cuz they "drive 70 miles with car and didnt hear anything". I was so fuming mad... I told him it was their idea to sit a technician with me and drive it, and he heard the noise while still in the lot. You can't argue with the fact. Regardless, I hear the noise alll day long, and the noise should get fixed since its coming from original MB parts. I was not treated well at this dealership and its not my only issue with them, just my latest. I have since decided to stay away from this horrible service dealership. They don't know how to treat clients. This is my 8th merceds, but the first mercedes I service in Valencia. Horrible experiences with my CLK500, I will return to servicing it in the valley. MB of Valencia won't make any more money from me!!!!! More
