2008 Mercedes-Benz E-Class FUEL/PROPULSION SYSTEM

The seal that connects the fuel level sensor to the fuel tank has failed, allowing fuel to leak onto the top of the tank when it’s filled. This creates a serious risk of fire or explosion. Unfortunately, Mercedes does not offer a remedy unless you pay a prohibitively high fee.

Smell of gasoline in the cabin and real bad outside of car

This is a PZEV vehicle. When the car is filled over 3/4th of the way, the driver's side near the back tire starts to leak the fuel. There was no warning lights, just the smell and the leaks. It's obvious why this is a safety hazard. This was not inspected by anyone other than myself as it was quite obvious after removing the back seat and accessing the sending unit location. This started after I resolved a fuel pump issue (back in March, resolved this month) Mercedes refused to handle ($3k) and noticed on or around 9/24/24.

I filled the vehicle up with gas and it started smelling very strong of gas for the next two weeks and I discovered gas underneath the driver's rear seat... I cleaned up the gas but continued to smell strong fuel Vapors and I'm just below three quarters of a tank the 15-year warranty is over. The Mercedes dealer says that they can't do anything for free and I feel this is a safety issue that needs to be rectified before someone dies in an explosion... no warning lights showed up but it is a common problem on the E-Class due to a cracked fuel filter housing module.

Gasoline smell all times inside of the car.

Very strong gas smell both inside and outside of the car with check engine light on. This happened in May of 2022. Could not park the car inside the garage. Contacted MBUSA, they said there is an extended warranty for this vehicle for this problem, advised me to take it to Mercedes dealer. I took the car to the dealer. They checked it out and said it is not covered under the extended warranty because it has passed the mileage ceiling for PZEV which I do not know what PZEV is. I checked The NHTSA website, it says 15 years unlimited miles. I had no other choice but to fix the car at the dealer and pay for the cost. A few months later MBUSA sent me a letter telling me although it has passed the mileage I might be eligible for a refund and wanted me to file a claim at the dealership. I did and after over two months the dealer again told me it is not covered. I paid about $1100 for the repair and told MBUSA that the dealer does not honor what the MBUSA letter says. Now even MBUSA does not honor what they wrote me in their own letter. They say if my car was non PZEV it would have been covered? How was it my fault to have a PZEV vehicle? Why did Mercedes had PZEV and non PZEV? How is it the customer fault. Both vehicles have the same issue but why one is covered and the other is not? Please you be the judge.

My car has smelled like gas for the past few years. Also it has not past inspection for the past 2 years. Mercedes said it was due to a defective intake manifold. Paid to replace the intake manifold and Mercedes said 2 new codes appeared. Now the gas tank, fuel pumps, brackets and hoses need to be replaced at a cost of of over 3500. The fuel pumps were replaced in 2014. Not sure why I continue to have problems with fuel pumps and now gas tank. Was informed this year after replacing the intake manifold that there was an extended warranty that concluded December 2022. I think Mercedes should resolve this as other vehicles had this same safety issue.

Smell Heavy gas smell inside of the vehicle but not in the engine bay. Stronger smell in the back seat. Afraid car my catch fire while driving. Having to drive with windows down so i don't get droggy.

LEAKING GAS TANK PVEZ, MERCEDES WILL NOT REPLACE IT, WAS UNDER RECALL.

WHEN CAR IS FILLED WITH GAS(FULL) , A GASOLINE ODOR CONSUMES MY GARAGE. WHEN WE OPEN GARAGE ALL YOU CAN SMELL IS GASOLINE. WHEN THE CAR GETS LESS THAN 1/2 TANK, THE FUEL ODOR SUBSIDES. USUALLY WHEN I TAKE IT TO DEALER I HAVE 1/4 TANK AND SMELL IS HARD TO DETECT. THIS HAS OCCURRED FOR OVER 2 YEARS BUT SMELL IS GETTING WORSE /STRONGER IT STARTING TO GIVE US HEADACHES

STRONG FUEL ODOR AFTER TOPPING OFF. I DROVE THE VEHICLE AND IT STARTED TO LOSE POWER AND STALLED ON THE ROAD. THE CAR WAS TOWED IN THE MERCEDES BENZ DEALERSHIP.

THE FUEL TANK LEAKS STRONG GASOLINE VAPOR INTO THE PASSENGER COMPARTMENT AND OUTSIDE THE VEHICLE CREATING A FIRE HAZARD AND IMPERILS THE DRIVER'S ABILITY TO PROPERLY BREATHE. THE VAPORS ARE STRONGEST EVERYTIME THE FUEL TANK IS FILLED OVER HALF WAY. CURRENT REPAIRS ARE GOING TO COST $3000. THE MECHANIC SAYS THE ROOT CAUSE IS THE CALIFORNIA EMISSIONS REQUIRED COMPONENTS THAT ARE NONSTANDARD. THERE ARE NO PICTURES AS THE LEAKY FUEL TANK IS CONCEALED UNDER THE BACK SEAT, BELOW WHERE MY CHILDREN SIT.

I HAVE A 2008 MERCEDES E350 PZEV MODEL AND THE ISSUE I CAME ACROSS IS A MAJOR ONE. THESE MODELS IN PARTICULAR HAVE A BIG REPUTATION ON FAILING FUEL PUMPS, AND TO MAKE THINGS WORSE ON THE PZEV VERSIONS IT CAN NOT BE FIXED UNLESS THE WHOLE FUEL TANKED IS SWAPPED WITH A NEW ONE. THE FUEL PUMP IS LOCATED INSIDE THE GAS TANK AND ITS SEALED JUST SO THERE'S NO WAY OF FIXING THE ISSUE, ON THE OTHER HAND THE NON-PZEV MODELS HAVE A REPLACEABLE PUMP WHICH REDUCES THE WORK AND MONEY TO FIX THE ISSUE. MERCEDES HAS AN APPLIED EXTENDED FACTORY WARRANTY FOR THE MODEL W211 WHICH COVERS THIS ISSUE UNTIL 15YEARS / UNLIMITED MILES FOR NON-PZEV MODELS AND 15YEARS / 150K MILES FOR PZEV MODELS. I SEE THIS VERY WRONG BECAUSE THE PZEV MODELS ARE SUPER EXPENSIVE TO FIX AND MANY PEOPLE ARE OVER THE 150K MILE MARK. THIS TERM SHOULD HAVE BEEN APPLIED TO THE PZEV MODELS. I PURCHASED THIS VEHICLE FOR $3,200 BUT TO FIX THIS PROBLEM IT IS OVER THAN $3,500. I AM REQUESTING MERCEDES TO HELP ME ON THIS SITUATION AS THESE CARS ARE WELL KNOW TO FAIL IN THAT DEPARTMENT. AS IT STANDS THIS CAR IS UNSAFE TO DRIVE, IT RELEASES LOTS OF RAW GAS SMELL AND SOMETIMES IT WILL NOT START. I WANT MERCEDES TO TAKE FULL RESPONSIBILITY OF THIS MATTER BECAUSE THIS ISSUE COULD HAVE BEEN A COUPLE HUNDRED DOLLAR FIX IF THE DESIGN AFTER TANK WASN'T SO BAD. THERE ARE THOUSANDS OF PEOPLE COMPLAINING ABOUT THE SAME ISSUE WITH THE PZEV MODELS AND MOST OF THEM ARE OVER THE 150K MILE LIMIT WHICH IS NOT ENOUGH CONSIDERING THE AGE OF THE VEHICLES. *TR

MY MBZ E350 IS LEAKING FUEL. VERY STRONG SMELL BOTH FROM INSIDE AND OUTSIDE. I BELIEVE THIS IS EXTREMELY DANGEROUS TO THE DRIVER AND OR PASSENGER IN MY CAR. ALSO, WHEN GAS TANK GETS FILLED UP, MY E350 ENGINE WILL START BUT IT WILL DIE WITHIN 5 TO 7 SECONDS. I'VE CONTACTED MBZ USA TO INQUIRE ABOUT THE ISSUE, I WAS INFORMED THAT THERE'S NO EXTENDED WARRANTY AVAILABLE TO ADDRESS THE ISSUE. BUT I'VE COUPLE OF DOCUMENTS RELATED TO SAME ISSUE IN WHICH MBZ STATED THAT THEY'RE EXTEND THE WARRANTY TO FUEL COMPONENTS.

TL* THE CONTACT OWNS A 2008 MERCEDES-BENZ E550. WHILE OPERATING THE VEHICLE, THE FUEL GAUGE DISPLAYED INACCURATE FUEL LEVELS AND A STRONG ODOR OF FUEL WAS PRESENT COMING FROM THE EXHAUST. THE VEHICLE WAS TAKEN TO MERCEDES-BENZ OF AUSTIN (6757 AIRPORT BLVD, AUSTIN, TX) WHERE IT WAS DIAGNOSED THAT THE FUEL LEVELING SENSOR WAS FAULTY AND THE FUEL TANK NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 160,000. THE VIN WAS UNKNOWN.

THIS IS ABOUT 5 YEARS I AM SMELLING GAS FUEL INSIDE THE CAR.BUT ON 05/24/2019 DRIVING ON THE STREET ,SUDDENLY CAR STOPPED MIDDLE OF STREET,AFTER TOWING THE CAR TO MECHANIC SHOP ,WE FIND OUT FUEL PUMP PROBLEM AND UNABLE TO CHANGE THE PUMP WE NEED TO BUY FUEL TANK AND FUEL PUMP,WHICH IS VERY EXPENSIVE.THIS SHOULD BE ON RECALL.BECAUSE TOO MANY PEOPLE COMPLAING (ACCORDING TO YOUR SITE)..CAR IS 115000 MILE.WARRANTY ARE 150000 OR 15 YEARS...JUST IMAGINE IF I WAS DRIVING ON FREEWAY WITH MY WIFE...THANKS IN ADVANCE

CAR SMELLS OF GASOLINE INSIDE AND OUT. CAUSING HEADACHES, FEARING FIRE OR EXPLOSIONS

FUEL HAS BEEN POOLING ON THE TOP OF THE FUEL PUMP NEAR SENDING, FOR MONTHS I WOULD SMELL GAS AFTER FILLING UP OR EVEN AT ABOUT 3/4 OF A TANK. ASSUMING I HAD PUT IN TOO MUCH; INSIDE FUEL FILLER COVER IT WARNS NOT TO TOP OFF TANK. SOMETHING I DIDN'T SEE UNTIL AFTER THE SMELL OF FUMES. UNDER MB'S PZEV WARRANTY IT STATES THAT IF THIS IS A PART THAT COULD BECOME DEFECTIVE AND HAS GIVEN OWNERS 15 YEARS/150,000 WHICHEVER COMES FIRST TO FILE A WARRANTY CLAIM AND HAVE IT REPAIRED OR REPLACED AT NO COST TO THE OWNER. MY VEHICLE HAS BEEN OUT COMMISSION FOR ALMOST 2 MONTHS BECAUSE THEY SIMPLY BELIEVE THAT I HAVE NOT MAINTAIN SERVICE OF MY VEHICLE, ACCORDING TO A COMMENT MADE BY ONE OF THEIR CUSTOMER SERVICE REPRESENTATIVES ( CALLS ARE RECORDED, DEBBIE WAS THE AGENT'S NAME AND CALL WAS MADE APPROXIMATELY AROUND 10:15 AM ON TUESDAY 2/19/2019. THE DIAGNOSTIC EVALUATION PERFORMED AT PARK PLACE MOTORS CO. IN ARLINGTON TX, DETERMINED THAT IT WAS MY FUEL PUMP AND NOT THE SENDING UNIT, STATED IN THEIR WARRANTY ALL FUEL SYSTEM COMPONENTS ARE INCLUDED PROVIDED THE VEHICLE IS WITHIN THE WARRANTY COVERAGE PERIOD. MY VEHICLE HAS 142,164 MILES AND IS JUST SHY OF 11 YEARS OLD. AFTER VIEWING AND RECEIVING REPORTS OF OTHER OWNERS WHO HAVE HAD SIMILAR ISSUES HAVE THEIR VEHICLES FIXED, AGAIN I BELIEVE THIS TO BE DISCRIMINATORY ON THE PART OF THE DEALERSHIP AND MBUSA AND ASK THAT CONTACT BE MADE TO EITHER OR BOTH TO CLARIFY WHY MY VEHICLE DOES NOT FALL WITHIN THE GUIDELINES OF THEIR WRITTEN WARRANTY COVERAGE.

CAR WAS BEING DRIVEN ON A BUSY CITY STREET, STOPPED FOR RED LIGHT, WHEN I WENT TO ACCELERATE I HAD TO PUMP THE PEDAL-TO BE SAFE I DECIDED TO TURN ONTO STREET AT INTERSECTION WHERE I WAS STOPPED AT LIGHT, CAR CAME TO A DEAD STOP IN MIDDLE OF STREET. THIS WAS VERY CLOSE TO THE FREEWAY ON RAMP THAT I WAS GOING TO. ANOTHER 1/2 MILE AND HAD I NOT DECIDED TO TURN OFF ON TO THE SIDE STREET THE CAR WOULD HAVE STOPPED IN THE MIDDLE OF A FREEWAY WITH PROBABLE FATALITIES. CAR HAD TO BE TOWED TO REPAIR SHOP. FUEL PUMP IS INSIDE GAS TANK IN THIS MODEL. REPAIR WAS $3373.88. MERCEDES BENZ DEALER HAS PARTS IN STOCK FOR A 2008 MODEL. THIS IS IN ITSELF IS UNUSUAL AND SEEMS LIKE THEY ARE EXPECTING MULTIPLE FAILS. THERE ARE ALSO MULTIPLE REPORTS OF SAME DOING AN ONLINE SEARCH. SHOULD BE RECALLED IN MY OPINION.I HAVE THE REPAIR RECEIPT AND ALL MY PREVIOUS RECORDS FOR MAINTENANCE ON THE CAR.

AFTER I FILLED THE GASOLINE TANK I NOTICED A STRONG GASOLINE SMELL INSIDE THE CABIN. I GOT A BAD HEADACHE FROM THE FUMES BEFORE I GOT HOME. I DID NOT SMELL ANY GAS IN THE TRUNK, ENGINE COMPARTMENT OR IN THE FUEL FILLER DOOR. I VENTILATED THE CABIN AND TRIED TO DETERMINE WHERE THE SMELL WAS COMING FROM. IT SEEMED TO BE UNDER THE DRIVERS SEAT OR BACK SEAT. EVEN AFTER SITTING ALL NIGHT AND HAVING ALL THE WINDOWS OPEN ALL DAY IT STILL WREAKS OF GASOLINE INSIDE. THE SMELL HAS NOT LEFT THE CABIN AND I AM AFRAID TO DRIVE THE CAR.

DROVE THE CAR 20 MINUTES STARTED TO NOTICE SMELL OUT OF THE BACK SEAT GASOLINE 5 MIN LATER IT STALLED 2 STREETS FROM MY HOUSE. . TRYED STARTING THE CRANKING OVER BUT NO START. THE NEXT DAY SHOP CALLED TOLD ME THAT BOTH OF THE FUEL PUMPS IN THE GAS TANK ARE BAD. 1.500.00 DOLLAR REPAIR. IS THAT SAFE FOR FUEL PUMPS DO DO THAT
