general problems of the 2003 Mercedes Benz 320

Red warning light illuminated on dash flashing warning driver " reduced braking effect visit workshop" and " increase braking distance visit workshop:. After research this warning is displayed because the sensotronic braking system has failed and reverted to hydraulic system has taken effect as backup. This condition was subject to nhstb recall #'s 2004050014 and 2005110001. I contacted mercedes USA customer service and was refused help. I asked to speak to someone up the chain of command and received a call from a case manager who stated that my vehicle had been repaired by mercedes and that they had no further obligation to assist me with this problem. I have studied mercedes service bulletins and by their own admission the vehicles that are subject to these recalls have notes within the service bulletin that "please note that recall and service campaigns do not expire and may be preformed on a vehicle with a vehicle status indicator" it is further stated in mercedes service bulletin that the "sensotronic brake control unit pump motor may run out of permissible tolerances thereby triggering the hydraulic back up function mode. Further, "greater brake pedal pressure is required and the brake pedal travel will be noticeably longer which could lead to a vehicle crash". To this day mercedes engineers are attempting to repair this problem with software fixes which is the subject of another mercedes service bulletin. The refusal of mercedes to repair an obvious hazardous condition of a component that does not function as designed in unacceptable. It is my opinion that the vehicle poses a threat to not only the operator but others if operated under these conditions. Please help me I have not allowed my wife to operate what I believe to be an unsafe vehicle.

First incident, brakes, visit workshop message appeared on the information system. Took the car to the dealer and vehicle was diagnosed with sbc pump failure. Mercedes had extended this warranty to 10 years because of know defects to the part so all parts and labor were covered.

While driving my e-320 I heard a loud popping sound come through the speakers. After I heard the sound the rear speakers and the sub woofer began to make a noised that suggested they were busted. When I stop the car and shut it off I heard a buzzing noise come through the speakers. Now when ever I apply the brakes I hear what sounds like a faulty ground noise coming through the speakers. There have been recalls on the brakes electrical system that sounds just like the problem that I am having but mb said my car is not included in the recall, by the way the to door speakers cost 189. 00 dollars a piece and the rear sub woofer cost 639. 00 dollars. I haven't started the research on how much the radio unit cost. This car has giving me several problems. What a beautiful lemon. .
