ON A HOT HUMID DAY ON JULY 21, 2019 AFTER DRIVING FOR 70 MINUTES OF MOSTLY HIGHWAY MILEAGE, THERE WAS A STRONG GAS SMELL AS I EXITED THE DRIVER'S SIDE DOOR. MY DAUGHTER EXITING THE REAR PASSENGER SIDE DOOR ALSO NOTICED THE INTENSE SMELL OF GASOLINE. THE NEXT DAY, I DROVE A SHORT DISTANCE OF 7 MINUTES AND AGAIN I NOTICE STRONG NAUSEATING GAS SMELL AS I EXITED THE CAR. CALLED THE DEALERSHIP AND TOLD TO BRING CAR IN AS SOON AS POSSIBLE. I WAS INFORMED THAT THE FUEL FILTER CRACKED. I RESEARCHED THE INTERNET AND NOTED THAT THE 2011 AND 2012 GLK350 MODELS WERE ON RECALL LIST; HOWEVER THE 2010 MODEL WAS NOT! I WAS GIVEN AN ESTIMATE OF $1250 (LABOR AND PARTS INCLUDED) FOR THE REPLACEMENT OF NEW FUEL FILTER. I WILL UPLOAD RECEIPTS AS SOON AS THE JOB IS COMPLETED (I AM WAITING FOR THE WORK TO BE COMPLETED AS I TYPE THIS REPORT).

OUR CAR HAS DEVELOPED A SERIOUS FUEL LEAK ON THE DRIVERS SIDE REAR. WHEN THE TANK IS FILLED TO CAPACITY, OR NEAR CAPACITY, A SERIOUS GASOLINE ODOR DEVELOPS. THE OTHER NIGHT WHEN WE DISCOVERED THIS PROBLEM, OUR ENTIRE HOME BECAME ENGULFED IN THESE FUMES AND WE HAD TO REMOVE THE CAR FROM THE GARAGE AND PUT IT OUT ON THE STREET. ALSO, WHEN WE MOVED THE CAR OUT OF THE GARAGE, WE NOTICED GASOLINE WAS DRIPPING FROM UNDER THE CAR AND FORMED TRAIL OF GAS ALL THE WAY OUT INTO THE STREET. THE LEAK IS CAUSED BY A FAULTY FUEL FILTER/FILTER HOUSING. THIS PARTICULAR PART IS WHAT WAS RECALLED AND REPLACED BY MERCEDES BENZ IN THE 20011 AND 2012 MODEL YEARS. OUR CAR IS A MODEL YEAR 2010, BUT IT HAS THE SAME FUEL FILTER (PART #2214700390 FROM AUTOHAUS AZ)) AND IF YOU SHOP FOR A NEW ONE, YOU CAN SEE IT IS THE SAME FOR THE YEARS 2010 THRU 2012. THE FUEL FILTER IS AT THE TOP OF THE TANK AND CAN EASILY BE REPLACED BY REMOVING THE RIGHT REAR PASSENGER SEAT. HOWEVER, THE ODOR AND FUMES AT TIMES WILL ENTER THE CABIN OF THE VEHICLE, AND IF THE CAR IS PARKED ON AN INCLINE, LEANING FROM RIGHT TO LEFT, I AM SURE GAS CAN TRAVEL ACROSS THE UNDERCARRIAGE AND OVER THE HOT EXHAUST.

EXTREMELY STRONG SMELL OF GASOLINE WHEN TANK IS FILLED, MERCEDES BENZ RECALLED 2011 AND 2012 MODEL YEAR GLK350 VEHICLES FOR A FUEL LEAK BUT DID NOT RECALL MODEL YEAR 2010 GLK350 VEHICLES. THE SAME RECALL IS NECESSARY FOR MODEL YEAR 2010 GLK 350 VEHICLES.

I PULLED INTO MY GARAGE AND NOTICED A STRONG SMELL OF GAS AS SOON AS I GOT OUT OF THE CAR. AFTER BEING IN THE HOUSE APPROXIMATELY 2 HOURS, THE SMELL OF GAS FILLED THE HOUSE. I PULLED THE VEHICLE OUT OF THE GARAGE AND IT CREATED A TRAIL OF GAS INSIDE THE GARAGE. MBUSA REFUSED TO COVER THE REPAIR AND ALSO REFUSED TO DISCLOSE INFORMATION RELATED TO THIS ISSUE WHEN I REQUESTED MORE INFORMATION FROM THE CUSTOMER REFERRAL REPRESENTATIVE. I'M PRETTY SURE IT'S NOT SAFE TO JUST HAVE FUEL BEING TRAILED UP AND DOWN HIGHWAYS AND EVERYONE IS UNAWARE. HOPEFULLY THEY CAN BE FINED FOR ENDANGERING PEOPLE.

THIS LAST TWO WEEKS, WE NOTICED THAT THERE'S A STRONG SMELL OF GAS. THERE'S NO LEAK THAT WE COULD SEE BUT THE ODOR IS STRONG THAT GIVES US HEADACHES. WE ARE DOING A RESEARCH ON WHY THIS IS HAPPENING BUT THE ONLY THING WE SEE ABOUT IT ONLINE IS ABOUT THE LINK BETWEEN GAS TANKS AND GAS FILTER. PLEASE HELP.

I NOTICED THE SMELL AFTER LEAVING THE GAS STATION AND BRINGING THE CAR HOME TO PARK IT IN MY GARAGE.THE GAS SMELL IS SO STRONG, IT LEAKS INTO THE HOUSE (VIA ATTACHED GARAGE). INITIALLY I ASSUMED THAT I MUST HAVE JUST SPILLED A LITTLE GAS WHILE PUMPING IT. HOWEVER, THE SECOND TIME I WENT TO FILL THE CAR UP THE SAME EXACT THING HAPPENED. TO DATE WE HAVE NO REMEDY FOR THIS PROBLEM. AGAIN, THIS HAS HAPPENED TWICE SO FAR.
