2006 MERCEDES-BENZ AMG CLS55 Complaints

EVERY TIME I FILL UP THE CAR WITH GASOLINE, THERE IS A VERY STRONG ODOR OF FUEL BOTH INSIDE AND OUTSIDE THE CABIN. THIS ODOR WILL LAST FOR A FEW DAYS UNTIL THE GAS EVAPORATE. I HAVE CHECK WITH THE MB SERVICE DEALER, THEY TOLD ME THAT A SERVICE CAMPAIGN #2008020001 FOR THE FUEL FILTER MODULE HAD BEEN DONE ON MY CAR IN MAY 2008 BY MB. IT LOOKS THAT THE SAME PROBLEM OCCURRING AGAIN. I HAVE PURCHASE THIS CAR IN NOVEMBER 2013 AND ALWAYS HAD THIS PROBLEM SINCE. *TR

AFTER PURCHASING A USED MB CLS55 AMG I NOTICED I KEPT SMELLING FUEL INSIDE THE CABIN OF MY VEHICLE AFTER FILLING UP WITH FUEL. DID NOT PUT ANY MIND TO IT TILL AFTER THE THIRD FILL UP. AND I DID A RESEARCH ONLINE AND NOTICED ITS A COMMON PROBLEM I THEN CALLED THE 800# AND ASKED IF THE RECALL CAMPAIGN #2008-020001 WAS EVER PERFORMED ON MY VEHICLE AND THEY SAID IT WAS DONE IN 2008 BY THE PREVIOUS OWNER. I TOLD HIM THAT THE PROBLEM SEEMS TO BE HAPPENING AGAIN AND THE CUSTOMER SERVICE REP TOLD ME THEY ONLY PERFORM THE RECALL ONCE AND IT IS UP TO THE OWNER TO PAY FOR THE PROBLEM THE SECOND TIME. SO I GUESS IM STUCK WITH A BIG BILL FOR SOMETHING THAT WAS NEVER REPAIRED PROPERLY FROM THE FIRST TIME. THATS WHAT LED ME TO THIS SITE HOPEFULLY SOMEBODY WILL READ THIS AND DO SOMETHING ABOUT A BANDAID THAT WAS PLACED ON THE CAR (BASICALLY REPLACED PART WITH THE SAME PART BUT NEWER THAT WAS DEFECTIVE FROM DAY1). *TR

CRACKS AT THE TOP OF THE FUEL SENDING UNIT CAUSE FUEL TO LEAK OUT AFTER FILLING TANK. FUEL SMELL IN CABIN EXTREME, FUEL THEN LEAKS OUT NEAR LEFT REAR WHEEL AND POOLS WHERE PARKED. CERTAINLY A SAFETY ISSUE! *TR

AFTER FILL UP STARTED SMELLING STRONG FUMES OF GAS IN VEHICLE. AFTER ABOUT 2 DAYS OF SITTING GOT IN VEHICLE THE SMELL WAS UNBEARABLE. TRIED TO RIDE SOME OF THE FUEL OFF THINKING IT WOULD TAKE AWAY SMELL, BUT TO NO AVAIL. DECIDED TO REMOVE BACK SEATS TO SEE IF SENDING UNITS WERE LEAKING IN WHICH I HAD HEARD ABOUT THRU MB FORUMS AND WOW THERE IT WAS THE REAR PASSENGER SEAT THE SIDE WHERE THE FUEL GOES IN WAS SOAKED UNDERNEATH AND VERY DAMP ON TOP OF TANK WITH FUEL, ON THE DRIVER'S SIDE IT WAS THE FUEL SMELL NOT DAMP LIKE THE OTHER SIDE, BUT SEAT WAS STRONG OF THE ODOR OF GAS. WHAT CAN BE DONE ABOUT THIS IS WHAT I WANT TO KNOW. THIS COULD BE VERY DANGEROUS IM AFRAID TO DRIVE CAR NOW. *JS

I AM AMONG THE HUNDREDS OF COMPLAINTS I HAVE READ ABOUT WITH MERCEDES FUEL TANKS LEAKING. I HAVE A CLS55 AND FOR THE LAST 2+ YEARS I HAVE BEEN ARGUING WITH MERCEDES ABOUT A VERY STRONG FUEL SMELL INSIDE AND OUT OF THE VEHICLE. WHILE IN WARRANTY, MY LOCAL DEALER TRIED TO REPAIR THE PROBLEM BY REPLACING THE SENDING UNIT TWICE. TO NO AVAIL, THE PROBLEM WAS NEVER DIAGNOSED AND OR REPAIRED CORRECTLY. NOW THAT I AM CURRENTLY OUT OF WARRANTY, THEY SEEM TO KNOW WHAT THE PROBLEM IS. I NEED A NEW FUEL TANK. I WON'T MENTION WHAT THEY QUOTED TO REPAIR IT. I HAD AN OUTSIDE MECHANIC INSPECT THE SENDING UNIT AND TANK AND I COULD VERY CLEARLY SEE THE FUEL POURING FROM THE TOP OF THE TANK AND POOLING AT THE SENDING UNIT. THE FUEL PUMP WAS ALSO LEAKING. I HAVE SPENT MANY HUNDREDS OF HOURS DISCUSSING THIS WITH DEALERS AS WELL AS MBUSA, AND THE END RESULT WAS THAT IT WILL NOT BE REPAIRED. THEY OFFERED TO REPLACE THE TANK FOR $1000 OUT OF POCKET COST TO ME. I AM DISGUSTED BY THE WAY I HAVE BEEN TREATED AND THEIR LACK OF RESPONSIBILITY FOR THE SAFETY OF EVERYONE ON THE ROAD. IF YOU EVER SEE A SILVER CLS55 IN THE HOUSTON AREA, PLEASE DO NOT SMOKE OR LIGHT A MATCH NEXT TO IT. *TR

STRONG ODOR OF FUEL AFTER FILLING TANK. THIS QUICKLY LEAD TO FUEL ODOR ANYTIME CAR WAS STARTED. I BECAME AWARE OF SIMILAR PROBLEMS POSTED ABOUT MY VEHICLE ONLINE. I REMOVED THE BACK PASSENGER SEAT AND INSPECTED THE FUEL PUMP BELOW PANELS AND FOUND THAT THE DRIVER SIDE PLASTIC PUMP HANGER ASSEMBLY IS LEAKING AT THE PLASTIC 90 DEGREE FITTING AND FILLING THE AREA WITH FUEL AND SPILLING OVER ONTO THE TOP OF THE TANK. THE VEHICLE IS UNSAFE TO DRIVE WITH THE AMOUNT OF FUEL ESCAPING. *TR

I OQN A 2006 MERCEDES CLS55 AMG. LAST YEAR I STARTED TO SMELL FUEL FROM OUTSIDE THE CAR AND ESPECIALLY ON THE DRIVER SIDE. THE THE SMELL STARTED TO PERMIATE THE INTERIOR. THIS WAS ESPECIALLY EVIDENT WHEN THE TANK WAS NEARLY FULL. I TOOK IT TO THE DEALER AND WAS TOLD IT WAS SENDING UNITS AND I PAID 1200.00 (APROX) TO HAVE TWO NEW SENDING UNITS INSTALLED. NOW, ONE YEAR LATER I AM NOTICING THE SEVERE SMELL AGAIN. I REMOVED THE BACK SEAT AND SEE FUEL EXPOSED ON THE TOP OF THE TANK. THIS CAN NOT BE GOOD! I AM SURE YOU ARE AWARE THAT THE CLS IS ON THE SAME CHASIS AS THE E-CLASS. I HAVE ALREADY READ OF THE ONGOING PROBLEM WITH THIS MODEL. I WANT TO MAKE YOU AWARE OF THE SAME SITUATION ON MY MODEL. *TR

STRONG FUEL ODOR INSIDE CABIN, AND FUEL LEAK ON GROUND OUTSIDE. REPAIRED TWICE UNDER WARRANTY. FIRST REPAIR FAILED; SECOND REPAIR TEMPORARILY SUCCESSFUL. SINCE SECOND REPAIR, FUEL ODOR FAINT BUT NOTICEABLE, SPORADIC, BUT WITH NO FUEL LEAK VISIBLE ON GROUND OUTSIDE. USUALLY OCCURS WHEN CAR IS STARTED AFTER SITTING IN THE SUN FOR SOME TIME IN HOT WEATHER, AFTER A RECENT REFUELING. INCIDENCE ABOUT ONCE MONTHLY (CAR IS USUALLY NOT PARKED OUTSIDE). THE CAR IS NO LONGER UNDER ANY WARRANTY. INDEPENDENT MECHANIC SHOWED ME THE (ORIGINAL) PLASTIC PART OVER THE FUEL TANK UNDER THE LEFT REAR SEAT WHICH SHOWED SLIGHT FUEL SEEPAGE (THE REPLACED-UNDER-WARRANTY PLASTIC PART UNDER THE RIGHT REAR SEAT STILL LOOKS NEW AND UNAFFECTED). IN MY OPINION, THIS MATTER IS RELATED TO THE 2003-2008 MERCEDES-BENZ E-CLASS FUEL ODOR INCIDENTS UNDER CURRENT (RECENTLY UPGRADED) NHTSA INVESTIGATION. *TR

AFTER FILLING GAS TANK THERE IS STRONG SMELL OF GAS INSIDE AND OUTSIDE CAR. DEALER REPLACED LEFT FUEL LEVEL SENDER AND RIGHT SIDE SEAL AT A COST OF $1535.86. PROBLEM IS RECURRING AFTER EACH FILL UP. *TR

REFERENCE PE12001 & EA13003 AFTER FILLING UP I SMELLED A STRONG GASOLINE ODOR IN THE CAR. UPON FURTHER INSPECTION, THE ODOR WAS COMING FROM THE REAR OF THE CAR. IT SMELLED LIKE THE DRIVERS SIDE REAR SEAT CUSHION HAD BEEN SOAKED IN GASOLINE. THE ODOR WAS SO STRONG, DRIVING THE CAR WITH THE WINDOWS UP WAS IMPOSSIBLE. I DID SOME RESEARCH ONLINE AND FOUND OUT THAT THIS WAS A COMMON PROBLEM WITH THE MERCEDES AMG CARS. AS INSTRUCTED ONLINE, I REMOVED THE SEAT CUSHION OPENED AN ACCESS PANEL AND COULD SEE LIQUID GASOLINE POOLING ON TOP OF THE FUEL LEVEL SENDER UNIT. I COULD ALSO SEE WHERE THE UNIT HAD CRACKED, ALLOWING GAS TO ESCAPE THE TANK. I CONTACTED MBUSA ABOUT THIS PROBLEM AND THEY ADVISED ME TO SEE THE DEALER. AS EXPECTED, THE DEALER DIAGNOSED IT AS A FAULTY FUEL SENDER UNIT. THEY CONTACTED MERCEDES ON MY BEHALF TO ATTEMPT TO GET ASSISTANCE WITH THIS REPAIR. MERCEDES DENIED ALL ASSISTANCE UNDER THE STANDARD AND EMISSIONS WARRANTY LEAVING ME WITH OVER $1000 IN REPAIRS. IN 2009, MY CAR WAS PREVIOUSLY REPAIRED UNDER RECALL #2008-020001 WHICH WAS SUPPOSED TO FIX THIS PROBLEM, BUT IT CLEARLY FAILED TO FIX THE PROBLEM PERMANENTLY. I HAD TO GET MY CAR REPAIRED BY A THIRD PARTY REPAIR SHOP AND FEEL DISGUSTED BY THE MERCEDES INABILITY TO FIX SUCH A FAULTY AND SERIOUS DESIGN FLAW. THEY WOULD RATHER MAKE THEIR CUSTOMERS PAY $1000-2000 TO AVOID PASSING OUT FROM GASOLINE FUMES OR RISK BEING KILLED IN AN EXPLOSION FROM A COLLISION. *TR
