The Brakes Failed - At Mercedes Dealership for Over a Month My Wife could have been killed on the highway going 70MPH with no brakes The car was towed by Mercedes over a month ago and never returned. No one will talk to me. Mercedes will not speak with me. Nor have they contacted the dealer - Letter Enclosed No warning - Just brake failure. Prior to that we got a "Your cameras are not working message" a week prior and the car would warn you another car was there. But there was no car.
