THIS HAPPENED IN MY 2003 C320 AT 54,000 MILES. I INITIALLY NOTICED A LIGHT RUBBING OR GRINDING WHILE ACCELERATING, WITH LIGHT VIBRATION. AT THE DEALERSHIP I WAS TOLD I WOULD NEED A NEW TORQUE CONVERTER, NEW RADIATOR, AND A FLUID FLUSH. THE RADIATOR FLUID WAS MIXING WITH THE TRANSMISSION FLUID. AFTER THOSE REPAIRS, MY C320 WAS STILL SHIFTING HARD AND THE GRINDING NOISE WAS STILL THERE. IT TURNS OUT THE TRANSMISSION WAS RUINED AS WELL. TWO REPLACEMENT TRANSMISSIONS WERE NEEDED UNTIL IT WAS READY TO BE PICKED UP. I'VE BEEN TOLD THAT THE MI…

DURING THE FIVE YEARS WE HAVE OWNED THE CAR IT HAS HAD NUMEROUS ELECTRICAL PROBLEMS. ON AT LEAST 5 OCCASIONS ALL FUNCTION OF THE DASHBOARD WENT OUT WHILE DRIVING. WHEN THE CAR WAS RESTARTED EVERYTHING WAS FINE. SEAT CONTROLS HAVE BEEN REPLACED SEVERAL TIMES, AND THEY STILL OPERATE INTERMITTENTLY. THERE IS NO PROBLEM WITH THE BATTERY. THERE IS A SHORT SOMEPLACE, AND THE DEALER KEEPS SAYING THEY CAN'T FIX IT IF THEY CAN'T SEE IT. *TR

I PURCHASE MY 2003 MERCEDES FROM CARMAX IN 2 YEARS AGO. IT HAD 45,000 MILES WHEN I PURCHASED IT. FROM THE TIME I PURCHASE THIS CAR I HAD TO REPLACE THE SUNROOF MOTOR, REPLACE THE SHOCKS, REPLACE THE TRUCK LOCK, REPLACE THE FUEL TANK, AND I HAD SOME TRANSMISSION WORK DONE. MY BIGGEST PROBLEM IS HAVING TO REPLACE THE LOW BEAM LIGHTS EVERY 6 MONTHS. I SUSPECT THERE IS AN ELECTRICAL PROBLEM, BUT CANNOT COMPLETELY PROVE IT WITH THE MANUFACTURER. WITH 1 YEAR, I HAD TO REPLACE THE BULBS 3 TIMES. I HAD TO REPLACE THE FRONT LOW BEAM BULBS AND THE BRAK…

ON A 2003 C 320 MBNZ, THE RADIATOR NOW LEAKS INTO THE TRANSMISSION. THIS IS GOING TO REQUIRE THE RADIATOR TO BE REPLACED AND FOR THE TRANSMISSION TO BE FLUSHED. THIS LEAKING RADIATOR FLUID COULD HAVE ALREADY DAMAGED THE TRANSMISSION, AND IF SO, IT WILL HAVE TO BE REPLACED. THIS PROBLEM CAUSES A LACK OF POWER AND THEREFORE A LOSS OF ACCELERATION. IT HAPPENS WITHOUT ANY WARNING, OFTEN LEAVING YOU VULNERABLE DUE TO THE LOSS OF POWER, A POTENTIAL ACCIDENT WAITING TO HAPPEN. *TR
