I WAS DRIVING ON A BUSY STREET WHEN THE MERCEDES BENZ STARTED JERKING. AFTER STOPPING AT A RED LIGHT, I COULD NOT GET THE CAR TO ACCELERATE PAST 2ND GEAR; THUS, I WAS DRIVING ON A STREET WITH A 45 MPH SPEED LIMIT AT LESS THAN 20 MPH.

Owner report 10503648 · 2013-03-19 (March 19, 2013)
I SMELLED GASOLINE WHEN MY TWO CARS WERE PARKED IN THE GARAGE. THIS OCCURRED ONLY AFTER FILLING THE GAS TANKS (NO TOPPING OFF.) I THOUGHT IT WAS MY 2010 MBZ BUT THE DEALER CHECKED AND FOUND NO PROBLEM. I HAD MY 2004 MBZ CHECKED. THE DEALER TOLD ME I NEEDED A NEW GAS TANK, BECAUSE IT WAS LEAKING. MY CAR HAS 80K MILES AND LOOKS NEW; GARAGED, SERVICED AND NEVER IN AN ACCIDENT AND HAS NO LEAKS. A NEW GAS CAP DID NOT SOLVE THE PROBLEM. OVER THREE QUARTERS OF A TANK DOES NOT EMIT ANY ODOR, SO I DON'T FILL THE TANK COMPLETELY. I FEEL THE FUMES…
