WAS DRIVING ON ROAD WHEN VEHICLE STARTED SURGING, LIKE OUT OF FUEL, WENT DOWN ROAD A LITTLE FURTHER AND IT HAPPENED AGAIN .THIS TIME I SMELLED STRONG DIESEL FUEL FUMES. SMOKE STARTING COMING OUT FROM UNDER HOOD. . I PULLED OFF ROAD AND SHUT CAR OFF. I OPENED HOOD LOTS OF SMOKE AND ENGINE COMPARTMENT COMPLETELY SOAKED WITH DIESEL FUEL ! HAD TO CALL ROADSIDE ASSISTANCE. GOT TOWED IN TO MERCEDES BENZ OF NORTH HAVEN CT. SERVICE DEPT TODAY SAYS LOOKS LIKE A RODENT CHEWED SOMETHING IN YOUR ENGINE COMPARTMENT. AND THAT CAUSED YOUR FUEL LEAK. THEREFORE WE ARE NOT COVERING ANYTHING UNDER WARRANTY. IT WILL COST ABOUT $4500 TO FIX .THIS IS RIDICULOUS AND VEHICLE IS UNDER FULL WARRANTY AND EXTENDED WARRANTY ! I WAS DRIVING THIS CAR ALL DAY .IT BROKE DOWN AT 2:30 IN THE AFTERNOON..MERCEDES BENZ IS LUCKY THE CAR DIDN'T CATCH FIRER AND BURN TO THE GROUND. MAURO MOTORS NEEDS TO MAKE GOOD ON THE WARRANTY AND FIX AT NO CHARGE. I HAVE A AUTOMOTIVE BACKGROUND AND JUST CANT BUY WHAT THEY ARE SAYING THE CAUSE IS FROM..WE OWN 2 MB VEHICLES AND THIS IS UNHEARD OF. WE WILL CONTACT OUR LAWYER ABOUT THIS ISSUE IF NOT RESOLVED.
