Vehicle garaged in storage for summer. Upon returning strong odor of gasoline was detected. Reluctantly drove to dealership and prognoses was determined that (fuel pump strainer) had malfunction thus soaking the entire rear passenger compartment and seat cushion. Upon investigation Mercedes has had a problem in other C -models and has extended warranties for 15 additional years for this same problem. This vehicle is a S- 550 model. Dealership has denied any responsibility. I think the vehicle is unsafe at ANY SPEED. Never should fuel enter the passenger compartment of any vehicle. Video on file at dealership.

UPON REFULING MY AUTOMOBILE FULL I COULD SMELL A STRONG ODOR OF GAS FUMES. EARLIER THAT DAY I HAD AN IMPACT OF MY TIRE OVER A CURB. GAS FUMES COULD BE SMELLED NOT SO MUCH ON THE OUTSIDE OF THE AUTO BUT INSIDE WITHOUT ABATEMENT. UPON INSPECTION BY MERCEDES BENZ OF STOCKTON CA IT WAS DETERMINED A FUEL LEAK WAS PRESENT WITH THE CUSHION THAT SITS ON TOP OF THE FUEL SYSTEM WAS SOILED/STURATED UNDER THE REAR PASSENGER SEAT OF THE CAR. PICTURES TAKEN SUGGEST IT HAD BEEN WAS ONGOING POSSIBLELY FOR YEARS. THEY SUGGESTED HEAT CONTRIBUTED TO THE UNIT-SEAL CORROSION AND ITS SURROUNDINGS. IT IS NOT CLEAR WHY MY RIGHT REAR IMPACT WITH A CURB BROUGHT THIS ALL TO MY ATTENTION. HIGHLY COMBUSTIBLE SITUATION THAT WAS CLEARLY NOT DETECTED WITCH IS NOT COMPLETELY UNDERSTOOD THE SAME DAY I HAVE AN IMPACT TO THE RIGHT REAR TIRE JUMPING A CURB THEN GOING BACK OVER IT TO UNLODGE THE TIRE & ROCKER MOLDING FROM THE CURB & REFUEL I SMELL GAS FUMES. HIGHLY DANGEROUS USING PLASTIC SECURE GAS EXCHANGES ON SOMETHING PEOPLE SIT ON? HAS SIMULARITIES IN OTHER DRIVERS. NOT SURE WHY THAT DAY THE SEAL (PLASTIC) RUPTURED (AT PLASTIC LID)

MY S550 WHEN DRIVING WOULD SUDDENLY GIVE A MALFUNCTION SIGNAL. I TOOK IT TO THE DEALER, SERVICE REPLACED THE 2 FRONT STRUTS. NOW THE CALL WILL GIVE A SIGNAL, RED LETTERS, "DO NOT MOVE CAR" AND THE ENTIRE STRUT SYSTEM WILL STOP WORKING AND THE CAR BODY IS VIRTUALLY SITTING ATOP THE TIRES. THIS AFTER REPLACING THE 2 FRONT STRUTS! THE DEALERSHIP SEEMS TO BE AT A LOSS AND I CAN'T EVEN GET THEM TO RETURN MY CALLS. I DON'T THINK IT IS A STRUT PROBLEM BUT A COMPUTER GLITCH. I DON'T THINK IT WAS NECESSARY TO PAY FOR THE STRUT REPLACEMENT. I WOULD LIKE MY CAR FIXED OR A REFUND.
