WHEN THE GAS TANK IS FULL THERE IS A VERY STRONG GAS SMELL ALL AROUND THE AUTOMOBILE. THE VEHICLE IS PARKED WITH THE IGNITION OFF. THIS SHOULD NOT BE THE CASE. THE CEL WILL COME ON WITH CODE P0456. A SMOKE TEST OF THE FUEL FILLER NECK SHOWED THERE WAS A LEAK. PART NO: W0133-2075480. THIS PART IS THE SAME DESIGN AS WHAT IS ON THE CLS. THIS SAME FUEL SMELL ISSUE IS ON THE E CLASS AND CLS CLASS AND A WARRANTY EXTENSION HAS BEEN ISSUED FOR AN ADDITIONAL 15 YEARS BUT NOTHING FOR THE CLK. THIS IS A DANGEROUS ISSUE WITH HEAT AND FUEL AND IT SHOULD BE ADDRESSED BY MERCEDES NA . AFTER DISCUSSING WITH MERCEDES THEIR STANCE IS THIS IS A NORMAL WARE ITEM. I DO NOT BUY IT.
I'VE STARTED NOTICING A VERY STRONG SMELL OF GASOLINE COMING FROM THE DRIVER'S SIDE REAR WHEEL WELL AFTER FILLING UP THE CAR. THE GAS FILL DOOR IS ON PASSENGER SIDE. IN DOING SOME RESEARCH ON THE WEB, IT'S COME TO MY ATTENTION THAT THERE ARE MANY OTHER PEOPLE WITH MY MAKE AND MODEL WITH THE SAME PROBLEM. ALSO, A CLASS ACTION SUIT WAS FILED FOR THE S CLASS AND E CLASS MODELS OF MERCEDES THAT WERE HAVING THIS SAME GAS FUMES ISSUE AFTER FILLING UP THE TANK. MERCEDES OFFERED AN EXTENDED WARRANTY OF UP TO 15 ADDITIONAL YEARS FOR THE AFFECTED CARS. THEY ACKNOWLEDGED THAT IT WAS A CRACK IN THE TOP OF THE FUEL TANK, OR IN SOME CASES A SEAL ON A VENT HOSE THAT WAS THE PROBLEM. I'VE LEARNED THAT MY MODEL OF MERCEDES SHARES THE SAME FUEL TANK AS THE OTHER CARS MENTIONED ABOVE. I REACHED OUT TO MY LOCAL DEALER AND THEY SAID I SHOULD CALL THE HELP CENTER OF MERCEDES BENZ AND SEE IF THEY'D REPAIR MY ISSUE TOO. THEY TOLD ME THAT MY MAKE AND MODEL YEAR WAS NOT COVERED. I EXPRESSED MY CONCERN ABOUT THE STRONG GAS FUMES SMELL AND THE POSSIBILITY OF AN EXPLOSION IN MY GARAGE SHOULD A SPARK OR FLAME IGNITE THE FUMES. THEY DID NOT SEEM TO CARE AND TOLD ME IF I WAS A LOYAL CUSTOMER MAYBE THEY COULD DO MORE. I TOLD THEM THAT I SURE DIDN'T THINK THEIR RESPONSE TO ME WAS ANY WAY TO CREATE LOYALTY. I'M REALLY CONCERNED ABOUT THIS BUT SO FAR, MERCEDES HAS BASICALLY TOLD ME THEY WILL NOT HELP. PLEASE HELP!!

PULLED INTO THE DRIVEWAY ONE EVENING AND NOTICED A STRONG FUEL SMELL. USING A FLASHLIGHT, FOUND A DRIP COMING FROM UNDER THE PASSENGER SIDE REAR OF THE CAR. THE NEXT MORNING A LARGE GAS STAIN WAS APPARENT UNDER THE CAR, BUT THE DRIP HAD STOPPED. STARTED THE CAR AND THE GAS LEAK BEGAN AGAIN. DROPPED THE PANELS UNDER THE CAR AND THE LEAK IS COMING FROM THE TANK. THE VEHICLE IS NOW AT A DEALERSHIP AND THEY CLAIM THE TANK IS CRACKED. *TR
