AFTER I FILL THE TANK UP WITH GASOLINE THE CAR SMELLS LIKE GAS! ESPECIALLY IN THE REAR ON THE INSIDE AND OUT. HUGE SAFETY AND ENVIRONMENTAL ISSUE. SEEMS TO BE VERY COMMON WITH THIS YEAR AND SHOULD BE MADE A RECALL. FUEL VAPORS ARE UNHEALTHY TO BE BREATHING AND SHOULD NOT BE RELEASE INTO THE ATMOSPHERE. NOT TO MENTION MY GAS MILEAGE HAS DECREASED! IT SHOULD BE A RECALL AND NOT A "WEAR AND TEAR" ISSUE BECAUSE THE CAR CANNOT EVEN REGISTER THE ISSUE NO CEL (CHECK ENGINE LIGHT) APPEARS BUT YET THE FUEL IS OBVIOUSLY LEAKING. I READ INTO IT AND MANY PEOPLE SAY IT HAS TO DO WITH CRACKED HOUSINGS ON THE FUEL PUMP AND SENDER? PLEASE MAKE THIS A RECALL!! HUGER SAFETY CONCERN WHAT IF I CRASH AND THE CAR IGNITES FROM THE INSIDE!

LOW BEAM DRIVER SIDE HEADLIGHT IS OUT AND GOES OUT WHEN REPLACING BULB. I ALWAYS TAKE MY CAR TO THE MERCEDES DEALERSHIP, WHERE I PURCHASED NEW IN 2007, FOR MAINTENANCE. SERVICE REP SAYS THE WIRING IN HEADLAMP IS CORROSIVE AND NEEDS REPLACING. MY HUSBAND LOOKED AT THE WIRES AND THEY SEEM TO HAVE MELTED. THE LIGHTS HAVE TO BE REPLACED AT $350 EACH (X2) AND THE LABOR AS WELL TO REMOVE THE BUMPER AND PUT IN THE NEW LIGHTS. THIS SEEMS TO BE AN ISSUE W/ THESE CARS AND NEEDS TO BE CORRECTED OR RECALLED. I'VE NEVER HEARD OF ANOTHER VEHICLE DOING THIS, NOR COSTING NEARLY $1000 TO REPLACE TWO HEADLIGHTS, WHICH IS CRUCIAL FOR SAFETY. I HAVE LOOKED TO SEE IF THERE ARE ANY RECALLS BUT HAVE NOT SEEN ANY. PLEASE ADVISE IF THERE ARE.

I BELIEVE THIS IS RELATED TO NHTSA ACTION NUMBER EA13003. THERE APPEAR TO BE COMPLAINTS BY OTHERS AS WELL FOR THE 2007 C230 REGARDING THIS ISSUE. BASICALLY, WHENEVER I FILL UP MY TANK, I SMELL GAS OUTSIDE OF THE CAR, NOT INSIDE. THE SMELL SEEMS TO BE STRONGEST AT THE RIGHT SIDE PASSENGER MIRROR DOOR AREA NEAR THE HOOD OF THE CAR. THEN AFTER A GALLON OR TWO HAS BEEN USED, THE SMELL GOES AWAY. IT TOOK ME A WHILE TO REPRODUCE AND IDENTIFY THIS PATTERN BECAUSE I DON'T REFILL MY TANK ALL THAT OFTEN (I DRIVE ABOUT 2K MILES A YEAR.) I FIRST STARTED NOTICING THIS SMELL AROUND JUNE 2014 AFTER I HAD MY SPARK PLUGS REPLACED DUE TO THE RECOMMENDED AGE LIMITS. AT FIRST I THOUGHT IT WAS DUE TO THAT. SO I TOOK MY CAR TO THE DEALERSHIP AND THEY IDENTIFIED A LEAK AFTER I DESCRIBED MY PROBLEM. I HAVE LOST ALL CONFIDENCE IN MERCEDES DUE TO A NUMBER OF ISSUES ON MY LOW MILEAGE CAR, THAT I STARTED RESEARCHING THIS IN GOOGLE AND DISCOVERED OTHER PEOPLE DESCRIBING THE SAME PROBLEM OF FUEL ODOR WHEN THE TANK IS FULL. THIS LEAK ALSO CORROBORATES WHAT I HAVE NOTICED ON THE FUEL GAUGE; THE FUEL GAUGE DROPS FROM FULL TO 3/4 FULL AFTER DRIVING ABOUT ABOUT 25 MILES OR SO. THAT CAN'T BE RIGHT BECAUSE 25 MILES OR SO IS NOT EVEN 2 GALLONS OF FUEL, AND THE TANK HOLDS ABOUT 13 GALLONS, UNLESS THERE IS A LEAK. PLEASE SEE IF THE PROBLEM WHICH AFFECTED THE E CLASS MODELS FROM THE SAME TIME PERIOD IS AFFECTING THE C CLASS MODEL. THANK YOU.

THE 2007 MERCEDES BENZ C230 WITH 68,000 MILES HAS AFTER COMING TO A STOP - I WOULD PLACE FOOT ON ACCELERATOR AND THE VEHICLE NOT SHIFT OUT OF LOW GEAR. IT WOULD BARELY MOVE. ON OTHER OCCASIONS THE VEHICLE WOULD NOT GO AND THE VEHICLE RPM'S WOULD REV BEYOND NORMAL RPM'S. THIS COULD HAPPEN ALSO AT THIS COULD HAPPEN ALSO AT ANY SPEED I WAS ENTERING THE FREEWAY, AS I WAS TRYING TO ENTER INTO TRAFFIC TRYING TO ACCELERATE MY CAR WOULD NOT PICK UP SPEED, AND THE CAR LOST ACCELERATION ON A MAJOR HIGHWAY WHILE DRIVING AT A SPEED OF 65 MPH. I HAD TO PULL OVER TO THE SHOULDER AND SHUT OFF THE ENGINE FOR A FEW MINUTES. ONLY AFTER RESTARTING THE ENGINE, THE ACCELERATION IMPROVED. I HAVE EXPERIENCED THIS ISSUE THREE TIMES NOW AND AM CONCERNED ABOUT ME AND MY FAMILY'S SAFETY, WHY HAS MERCEDES BENZ NOT INITIATED A RECALL. I HOPE THE COMPANY IS NOT WAITING FOR A DISASTER TO HAPPEN. I WOULD APPRECIATE IF NHTSA COULD PLEASE INVESTIGATE THE ISSUE.

AUGUST OF THIS YEAR I HAD TO GET A SPEED SENSOR REPLACED THAT COST ME $1200.00 BECAUSE THE VEHICLE WOULD NOT GO OVER 30 MPH AND WAS RUNNING AT A HIGH RPM. THE VEHICLE DEMONSTRATED THIS PROBLEM OVER A YEAR BEFORE I ACTUALLY HAD TO TAKE IT INTO A REPAIR SHOP. I COULD USUALLY PULL OVER AND CUT THE CAR OFF AND CUT IT BACK ON AND IT WOULD CORRECT ITSELF WHICH WAS TOTALLY RIDICULOUS. SOMETHING REALLY NEEDS TO BE DONE PERTAINING TO THE FAULTY PARTS USED TO BUILD THESE VEHICLES. I FEEL MY $1200.00 ALSO NEEDS TO BE REFUNDED BACK TO ME IN A CHECK FORM ASAP. *TR

Vehicle speed control, Oct 15, 2014
I WAS DRIVING MY CAR AROUND 30MPH COMING TO A SLOW DOWN TO MAKE A RIGHT HAND TURN. MADE TURN AND PROCEEDED UP A STEEP HILL AND MY CAR SIMPLY STOP PULLING/ACCELERATING. THIS HAS HAPPENED SEVERAL TIMES. I WENT OUT OF TOWN TO TX FOR CHRISTMAS AND HAD THE SAME THING HAPPEN. I CAN'T UNDERSTAND WHY SO MANY COMPLAINTS AND NO ONE HAS YET TO EVEN INVESTIGATE THE PROBLEM. THE MAINTENANCE ON THESE VEHICLES IS EXPENSIVE. ON TOP OF THE MB IS FAMILIAR WITH THIS ISSUE AND SHOULD NOT BE PUTTING THIS EXPENSE OFF ON THE OWNERS DUE TO FAULTY DEFAULT PRODUCT THAT CAN NOT EVEN BE REBUILT BUT REQUIRES REPLACING THE FAULTY PART WITH ANOTHER FAULTY PART. SOMETHING NEEDS TO BE DONE ABOUT THIS. *TR
