2007 Mercedes-Benz CLK-Class Fuel System Problems

WHEN I FILL MY CAR UP I CAN SMELL GAS IN MY GARAGE. ONCE I DRIVE IT FOR A WHILE AND IT GETS BELOW A HALF TANK OR SO I DON'T SMELL THE GAS ANYMORE. I AM WORRIED THAT THE GAS SMELL IN THE GARAGE MADE SOME FUMES INTO MY HOUSE AND THIS IS A SAFETY ISSUE. I SEE SOME MODELS OF MERCEDES HAVE BEEN RECALLED FOR THIS REASON. I WOULD LIKE MERCEDES TO RECALL AND REPAIR THIS AT NO CHARGE TO ME. APPARENTLY MERCEDES COVERS MODEL YEAR 2003 TO 2009 ON THE E CLASS IN 2006 TO 2011 ON THE CLS CLASS. I AM HAVING THE EXACT SAME ISSUE. *BF *TR *TR

BOUGHT THE VEHICLE AT 42K MILES 3 YEARS AND IT SMELLS FUEL INSIDE THE VEHICLE AND THE GARAGE FOR A COUPLE OF DAYS ON EACH TANK FILL UP. IT SMELLS SO BAD I HAVE LEAVE THE GARAGE DOOR OPEN SOMETIMES SO THAT MY HOUSE DOES NOT CATCH FIRE ALONG THE VEHICLE. SEARCHED ONLINE A LOT OF OWNERS OF THE SAME VEHICLE HAVE THE SAME COMPLAINT.

WHEN I FILL THE GAS TANK, THERE IS A VERY STEONG SMELL OF FUEL INSIDE AND OUTSIDE OF THE CAR. THE SMELL IA THERE UTIL AT LEAST HALF THE TANK IS USED. THE SAME PROBLEM HAS BEEN WITH "E" SERIES. MB ISSUED A RECALL. HOWEVER, THE DEALERSHIP TELLS ME THERE IS NO RECALL FOR 2007 CLK350 EVENTHOUGH SAME PARTS ARE USED TO DELIVER THE FUEL.

STRONG SMELL OF FUEL FROM REAR LEFT SIDE OF VEHICLE AFTER FILL UP. FUEL PUDDLE FOUND UNDER REAR PASSENGER SEAT UNDER FUEL TANK ACCESS PANEL. LEFT SIDE FUEL PUMP (FUEL FILTER/SENDER) FOUND CRACKED AND LEAKING AT THE NIPPLE TO THE OUTGOING GAS LINE. THIS IS A COMMON FAILURE FOR 10 YEAR OLD E AND C CLASS MERCEDES AND IS PART OF A MERCEDES EXTENDED WARRANTY PROGRAM TO CORRECT THIS EXACT PROBLEM. HOWEVER, MERCEDES TELLS ME THAT MY CLK IS NOT PART OF THE WARRANTY EXTENSION.

AFTER FILLING GAS TANK STRONG GAS SMELL AROUND CAR SPECIALLY IN THE GARAGE NO VISIBLE FUEL LEAK.NO FUEL SMELL IN THE CAR ONLY OUTSIDE BY REAR WHEELS.NOT IN MOTION ,

GASOLINE FUMES ARE INSIDE AND OUTSIDE THE VEHICHLE AFTER FILLING THE TANK. MERCEDES AGREED TO WARRANTY THIS ISSUE FOR 15 YEARS ON THE E-CLASS AND CLS-CLASS IN EA 13-003. THESE COMPONENTS ARE THE SAME ON THIS MODEL (CLK). THE INVESTIGATION SHOULD BE REOPENED AND INCLUDE ALL EFFECTED MODELS.

FUEL TANK LEAK

STRONG ODOR OF GASOLINE, MAINLY AFTER REFUELING AND THEN CONTINUING WHEN DRIVING AND WHEN STATIONARY. MECHANIC ASSESSED THAT FUEL IS LEAKING FROM THE UPPER PART OF THE GAS TANK AND THE FUEL COMPONENTS.

VERY STRONG GASOLINE SMELL COMING FROM UNDER THE DRIVER SIDE REAR SEAT ESPECIALLY AFTER FILLING GAS TANK. MERCEDES AGREED TO WARRANTY THIS ISSUE FOR 15 YEARS ON THE E-CLASS AND CLS-CLASS. WHY DIDN'T MERCEDES AND NHTSA INCLUDE THIS MODEL (CLK) THAT HAS THE SAME PROBLEM WITH THE SAME COMPONENTS?

WHEN THE GAS TANK IS FILLED UP FUEL IS LEAKING FROM THE TOP OF THE TANK. AFTER THE CAR IS DRIVEN AND A FEW GALLONS OF FUEL ARE BURNED, THE SMELL IS NO LONGER NOTICEABLE. THE REPAIR FACILITY SAID THE FUEL SENDING UNIT AND NEED TO BE REPLACED.

FUEL IS LEAKING FROM BOTH SENDER UNITS WHEN TANK IS MORE THAN 3/4 FULL. EXTREME FUMES WHEN CAR IS PARKED IN CLOSED GARAGE WITH A FULL TANK. SMELLS LIKE A LARGE QUANTITY OF FUEL IS LEAKING. PAID FOR THE SAME REPAIR 20K MILES AGO, NOW SAME PROBLEM HAS RETURNED. MB DEALER WILL NOT COVER UNDER WARRANTY, COST FOR REPAIR IS $1800 (PLUS ORIGINAL REPAIR). THE SYMPTOMS ARE IDENTICAL TO INVESTIGATION EA 13-003. ARE SIMILAR PARTS INVOLVED? GIVEN THE VAST NUMBER OF COMPLAINTS HERE AND ONLINE FORUMS, AN INVESTIGATION SHOULD BE DONE. THERE IS NO WAY THIS AMOUNT OF FUEL LEAKING IS NOT A SAFETY ISSUE. THIS IS LITERALLY A "TICKING TIME BOMB".

A VERY STONG GASOLINE SMELL IN THE GARAGE AFTER HAVING CAR FILLED. THE STRONG SMELL HAS BEEN GOING ON FOR SOMETIME BUT DIDN'T THINK TOO MUCH ABOUT IT. LAST WEEK A PLUMBER CAME TO MY HOUSE FOR A LEAKY PIPE SITUATION AND NOTICED THE SMELL AND SAID THAT WAS NOT NORMAL AND COU LD PRESENT A FIRE HAZARD! I IMMEDIATELY TOOK THE CAR TO GREENWAY MERCEDES LATE ON TUESDAY, 9-29-15. I SAID I WON'T HAVE TO PAY FOR THIS BECAUSE IT MUST BE A DEFECT. THEY SAID INDEED I WOULD HAVE TO PAY. THE DIAGNOSTIC SHOWED THAT IT WAS THE SEALS IN THE FUEL SENDING UNIT, AND I PAID $1400 TO BE REPAIRED. I TOLD THEM I WAS GOING TO FILE A COMPLAINT WITH YOU BECAUSE I HAD RESEARCHED AND FOUND OTHER COMPLAINTS FILED FOR THE SAME PROBLEM WITH YOU.

THE VEHICLE STALLED, ENGINE QUIT, ON A BUSY SIDE STREET. THE DRIVER PULLED OVER ON THE DIRT SIDE OF THE STREET. RESTARTS WERE ATTEMPTED TO NO AVAIL. THE ENGINE WILL IDLE FOR A COUPLE OF SECONDS THEN SHUTDOWN. IT SOUNDED LIKE FUEL STARVATION. THE FUEL INDICATOR SHOWED 4 BARS OR A LITTLE UNDER HALF TANK. THE FUEL TANK WAS FILLED WITH 5 GALLONS OF GASOLINE WHERE THE VEHICLE STARTED FINE AND DRIVEN HOME. THE CAUSE WAS FOUND OUT TO BE A FAULTY FUEL INDICATOR. IT LATER FREEZES ON HALF FULL EVEN IF IT IS FILLED TO FULL TANK AT THE GAS STATION. FUEL GAUGE READINGS ARE INCORRECT AND INTERMITTENT. RESEARCH FROM NADA GUIDES ON THIS VEHICLE REVEALED US NHTSA CAMPAIGN ID 08V303000 AND MERCEDES BENZ RECALL NO. 2008 07000, REGARDING INCORRECT SOFTWARE CALIBRATION NUMBER CODING. HOWEVER, THIS VEHICLE'S VIN DOES NOT SHOW ANY RECALL OR SERVICE BULLETIN. UPDATED 09/25/15*LJ.......UPDATED 10/19/15 *BF UPDATED 12/21/2015 *JS UPDATED 01/25/16.*JB

TL* THE CONTACT OWNS A 2007 MERCEDES BENZ CLK350. UPON REFUELING THE VEHICLE, THE CONTACT SMELLED A STRONG ODOR OF FUEL OUTSIDE AND INSIDE THE VEHICLE. THE FAILURE PROGRESSED WITHOUT WARNING. THE VEHICLE WAS NOT INSPECTED AND DIAGNOSED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 99,942.

THERE IS A STRONG GAS SMELL COMING FROM THE VEHICLE ESPECIALLY AFTER FILLING UP THE TANK. IT WAS INSPECTED AT FLETCHER JONES MERCEDES BENZ DEALER AND THE LEAK WAS FOUND AT THE FUEL TANK FILTER, LEVEL SENSOR, AND 2 SEAL RINGS. DUE TO THE COST, I DID NOT HAVE THE VEHICLE REPAIRED AT THE DEALER BUT AT A LOCAL SHOP SPECIALIZING IN MB. COST FOR THE REPAIR WAS $836.70. I AM REPORTING THIS LATE FOR PURPOSES OF SAFETY AND TRENDING.

AFTER FILLING UP THE GAS TANK AND PARKING IT IN THE GARAGE IT GIVES OFF A TERRIBLE GAS ODOR WHICH GETS MORE AND MORE STRONG THE LONGER THE CAR IS IN THE GARAGE. ONCE THE CARS FUEL TANK EMPTIES SOMEWHAT IT SEEMS TO NOT EMIT THE GAS ODORS AS MUCH . SHAME ON MERCEDES USA FOR NOT DOING A RECALL ON THIS HAZARD. FOR A COMPANY THAT PRIDES ITSELF ON SAFETY.. I HAVE READ HUNDREDS ON THE EXACT SAME COMPLAINTS ALL OVER THE WEB. *TR

TL* THE CONTACT OWNS A 2007 MERCEDES BENZ CLK550. THE CONTACT STATED THAT WHILE PARKED, A FUEL ODOR EMITTED FROM THE INTERIOR AND EXTERIOR OF THE VEHICLE. THE CONTACT INSPECTED THE VEHICLE AND NOTICED THAT THERE WAS FUEL LEAKING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE FUEL SENDING UNIT NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGE WAS 15,889.

DRIVING DOWN THE ROAD AT A SLOW SPEED AND THE CAR JUST QUITS. SOMETIMES IT WILL START ITSELF BACK UP AND SOMETIMES I HAVE TO PULL OFF TO THE SIDE OF THE ROAD TO TURN IGNITION OFF AND THEN ON AGAIN. THE CAR WILL JUST QUIT AT HIGHWAY SPEEDS AND AFTER SOME QUICK THINKING AND REALIZING WHAT JUST HAPPENED THE ONLY THING TO DO IS DRIFT TO THE BERM OF THE ROAD WITH NO PWR STEERING OR BRAKES. THERE ARE ALSO TIMES WHEN I START THE CAR IT WILL QUIT AND TAKES TWO TO THREE MORE TRIES. ALSO HAD A SEVERE RAW GAS COMING FROM THE CAR AFTER A FILL UP. THE GAS FUMES WERE SO SEVERE THAT WE HAD TO PARK THE CAR OUTSIDE FOR FEAR OF AN EXPLOSION IN OUR GARAGE. I TOOK THE CAR TO THE MB DEALER IN PITTSBURGH AND THEY WERE ABLE TO REPAIR THE GAS PROBLEM AS THE GASKETS AROUND THE GAS TANK WERE DRY-ROTTED AND I PAID APPROX $600.00 FOR THIS REPAIR WHICH I FEEL THAT MB SHOULD HAVE COVERED SINCE AT 66000 MILES THIS SHOULD NOT HAPPEN. AS USUAL THEY COULD NOT DUPLICATE THE STALLING ISSUE. MB KNOW OF THIS PROBLEM BUT WILL NOT DO ANYTHING SINCE IT DOESN'T SHOW UP ON THERE COMPUTER HOOK-UPS. SOMETHING NEEDS TO BE DONE BEFORE PEOPLE GET KILLED. I'M SURE I'M NOT THE ONLY ONE THIS HAPPENS TOO. *TR

WHEN THE GAS TANK IS FILLED UP FUEL IS LEAKING FROM THE TOP OF THE TANK AND THERE IS A STRONG ODOR OF GASOLINE IN THE GARAGE. AFTER THE CAR IS DRIVEN AND A FEW GALLONS OF FUEL ARE BURNED, THE SMELL IS NO LONGER NOTICEABLE. THE REPAIR FACILITY SAID THE FUEL SENDING UNIT AND SEALS NEED TO BE REPLACED. *TR

THERE IS A VERY STRONG GAS SMELL. IT IS OVERWHELMING, LASTS FOR DAYS, AND WE NEED TO PARK THE CAR OUTSIDE OF THE GARAGE, AS THE SMELL IS SO INTENSE IT MAKES YOU FEEL SICK. IT JUST STARTED HAPPENING ABOUT A WEEK OR TWO AGO, AND SEEMS TO BE MOST OBVIOUS AFTER GETTING FUEL. I SEARCHED THE INTERNET AND FOUND THAT THIS SEEMS TO BE A VERY COMMON PROBLEM WITH A LOT OF MB OWNERS HAVING SIMILAR ISSUES. ALSO, THERE SEEMS TO BE A RECENT CLASS ACTION SUIT INITIATED BY THE NHTSA INVOLVING THIS PROBLEM. I'M CONCERNED THIS COULD BE A LIFE THREATENING SAFETY PROBLEM IF AN EXPLOSION OCCURS AND THE INTENSE FUMES SEEM LIKELY TO CAUSE OTHER HEALTH RELATED PROBLEMS. *TR
