I HAVE A 2003 C 320 MBNZ, THE RADIATOR LEAKS INTO THE TRANSMISSION. THE RADIATOR NEEDS TO BE REPLACED. THIS LEAKING RADIATOR FLUID DAMAGED THE TRANSMISSION, AND IT HAS TO BE REPLACED. THIS PROBLEM CAUSED A LACK OF POWER AND THEREFORE A LOSS OF ACCELERATION. IT HAPPENED WITHOUT ANY WARNING, LEAVING YOU VULNERABLE DUE TO THE LOSS OF POWER, A VERY DANGEROUS SITUATION WHICH MAY CAUSE AN ACCIDENT. THE CAR HAS ONLY 50026 MILES ON IT. *TR

MERCEDES BENZ POSSIBLE RECALL / EXTENDED WARRANTY FOR FUEL SYSTEM... INVOLVING A C CLASS 2003 WITH SAME ENGINE AS THE E CLASS. THE CAR FUEL SYSTEM IS TOTALLY MESSED UP, WILL ONLY FILL A HALF TANK AND RUNS OUT OF GAS BECAUSE THE FUEL TANK SYSTEM IS NOT WORKING CORRECTLY. CAR WILL NOT FILL. ONLY ONE TANK TAKING AND SENDING FUEL APPARENTLY. DASH IS MESSED UP, LIGHTS OUT, FUEL SYSTEM TOTALLY MESSED UP. I ALMOST WENT OFF A CLIFF IN THE CAR, SLID BACKWARDS ON A HILLSIDE WHEN THE CAR RAN OUT OF FUEL UNEXPECTEDLY. NO GAS, NO POWER, MY CAR WENT BACKWARDS, BRAKES NOT WORKING, I WENT INTO A DITCH AND ALMOST INTO A STEEP HILLSIDE, VERY SCARY. A CAR BRANCH SAVED MY DEMISE, HOLDING THE TOP OF THE CAR AND KEPT ME FROM GOING DOWN INTO A RAVENE. DENT ON THE BACK ROOF IS STILL THERE. MERCEDES BENZ REFUSES TO ACKNOWLEDGE ANY PROBLEMS ALTHOUGH THE PROBLEM IS APPARENTLY PROLIFIC IN CARS THIS YEAR AND TYPE. SAME FUEL SYSTEM ON A C320 AS AN E320 SAME YEAR. SAME ENGINE TOO. MY MECHANICS ARE BAFFLED, NO ONE CAN FIX IT, MERCEDES SHOPS DON'T WANT TO HELP, NO ONE CAN HELP.

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 BRAKE LIGHTS. THIS IS SURPRISING SINCE THIS CAR (UNDER MY OWNERSHIP) HAS NEVER BEEN IN AN ACCIDENT. I AM SO DISAPPOINTED I PURCHASED THIS CAR! *TR

THE FUEL GAUGE FAILED TO FUNCTION. IT DIDN'T REGISTER THE CORRECT GAS LEVEL IN THE TANK. THE DIGITAL CONSOLE LIGHT MALFUNCTIONED. IT WOULD EITHER NOT ILLUMINATE WHEN THE VEHICLE WAS STARTED OR WHEN ILLUMINATED IT WILL SUDDENLY GO OUT. THE VEHICLE HESITATED UPON ACCELERATION WHEN DRIVEN FOR LONG DISTANCES. *NLM

THE THROTTLE LINKAGE AND CONTROL PEDAL MALFUNCTION NEARLY RESULTED IN A SERIOUS ACCIDENT. THE BRAKES HAD TO BE VIOLENTLY APPLIED WITH BOTH FEET TO PREVENT THE SURGING VEHICLE FROM REAR-ENDING A VEHICLE IN FRONT OF MINE AT A TRAFFIC INTERSECTION.*AK

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

THE POWER STEERING WAS TIGHT AND IT WAS DIFFICULT TO CONTROL THE STEERING WHEEL. *JB *TT

BRAKING SYSTEM FAILURE MY WIFE WAS DRIVING TO WORK. SHE ATTEMPTED TO STOP AT AN INTERSECTION, HER FOOT WENT TO THE FLOOR WHILE BRAKING, RED LIGHT AND WARN BUZZER WENT OFF... NO BRAKES. LUCKILY AND THANK GOD, SHE AVOIDED BEING T-BONED IN THE INTERSECTION AND WAS ABLE TO GET IT INTO A PARKING LOT AND DOWN SHIFT TO USE E-BRAKE. THE CAR HAS ONLY 70,000MILES ON IT. THE REPAIR OF THE SYSTEM SOUNDS LIKE IT IS $2500+. NOT HAPPY AT ALL SINCE MB KNOWS IT IS A PROBLEM AND SHOULD HAVE A REPLACEMENT BRAKING SYSTEM FOR IT OR REPAIR. THIS IS NOT JUST A OLD MASTER CYLINDER GOING OUT. THIS IS A WHOLE SENSOR UNIT FAILING
