Mercedes Benz E550 problems and owner complaints

WHEN THE FUEL TANK IS FILLED THERE IS A STRONG SMELL OF FUEL UNDER THE DRIVERS SIDE REAR WHEEL BASE AND IN THE PASSENGER COMPARTMENT WITH ON OCCASION A SMALL LEAKAGE OF FUEL ON THE FLOOR. I HAVE SEARCHED THE INTERNET AND FOUND SIMILAR PROBLEMS ON SEVERAL W211 CARS. I CONTACTED THE DEALERSHIP ON SEVERAL OCCASIONS TO REPAIR THE PROBLEM AND THEY ARE NO HELP EXCEPT TO SAY IT WILL COST AROUND $2000 TO REPAIR THE PROBLEM. I DID FIND THAT THERE WAS SOME CORRESPONDENCE BETWEEN THE NHTSA THIS YEAR IN APRIL CONCERNING THIS MATTER BUT DID NOT KNOW THE OUT…

AFTER FILLING THE FUEL TANK (WITHOUT TOPPING-OFF AND WITHOUT ANY SPILLAGE) AND ARRIVING AT NEXT DESTINATION, THERE IS A STRONG GASOLINE ODOR ON THE DRIVER SIDE REAR OF THE VEHICLE. THIS IS THE SIDE OPPOSITE OF THE FILLER PIPE, SO IT IS NOT RELATED TO SPILLAGE DURING FILLING. THE ODOR LASTS UNTIL THE TANK IS DOWN TO APPROXIMATELY 3/4. UPON INSPECTION OF THE UNDER SIDE OF THE CAR, THERE IS A SMALL BUT NOTICEABLE WET AREA UNDER THE DRIVER SIDE REAR PASSENGER COMPARTMENT. SEARCHING THE INTERNET PROVIDES A VAST NUMBER OF PEOPLE WITH 2003-2009 E CLAS…

VERY STRONG SMELL OF GASOLINE OUTSIDE THE CAR WHEN PARKED; AND INSIDE WHEN DRIVING OR WHEN STOPPED WHILE DRIVING SLOW. THIS HAPPENED A DAY AFTER SERVICING THE CAR TRANSMISSION AT THE SAME DEALERSHIP.TOOK IT BACK TO DEALER, THEY CLAIM IT'S A VERY COMMON ISSUE AND THE CAR IS HAZARDOUS TO DRIVE BECAUSE GAS LEAK IS ON TOP OF EXHAUST AND CAN START A FIRE. IT NEEDED $3,000 REPAIRS (GAS TANK + FUEL PUMP & SENDING UNIT.) I WAS DRIVING A TIME BOMB WITH MY CHILDREN THE NIGHT BEFORE WITHOUT REALIZING IT. THERE SHOULD BE A RECALL FOR THIS DANGEROUS FACTOR…

THE CAR STARTED STALLING IN JERK MOTIONS AND STOPPED. IT HAPPENED COUPLE TIMES AND USUALLY HAPPENS AT TRAFFIC LIGHTS OR TRAFFIC JAM PLACES WHERE SPEED IS BELOW 20K. I WAS AFRAID THIS COULD HAVE CAUSED CARS BEHIND HIT ME. LATER AFTER COMPLETELY STOP OF THE ENGINE, I GOT A ENGINE CHECK LIGHT AND WHEN STARTING DRIVING , THE CAR SHOW LOT OF RPM BUT WOULD NOT DISPLACE/MOVE MUCH. THE CAR HAS 45K MILES AND CURRENTLY WITH THE DEALER SERVICE DEPARTMENT. THIS MIGHT BE A TRANSMISSION PROBLEM AND I FEEL THIS MB OF USA & NHTSA SHOULD INVESTIGATE TO GET A R…

In the fall of 2021 the car started to received errors related to the ABS control unit that failed preventing 1) antilock braking, control of ESP (limiting poor handling), and cruise control. At the time of the failure, the car only had 31,552 miles and was properly maintained. MB has extended a warranty for several models and years...but even though my 2008 E-Class is not included in the warranty extension, several models (thru 2012) had their warranty extended for 25 years. I have not been able to get a answer why the E-Class after 2006 wa…
