I PURCHASED A LAVISH S550 AND OVER TIME I STARTED SMELLING GAS IN THE CABIN. I DIDN'T THINK TOO MUCH ABOUT IT UNTIL THE SMELL BECAME MORE PUNGENT. I GO ONLINE TO DO SOME RESEARCH AND FIND OUT SOME OF THE CARS HAD FAULTY FUEL PUMPS WHICH LEAK INTO THE BACKSEAT. NOT ONLY DOES IT LEAK BUT THE VAPORS ARE SPREAD THROUGHOUT THE CABIN MAKING IT UNBEARABLE TO BREATH. I TOOK THE CAR IN TO MERCEDES AND THEY DON'T WANNA OWN UP TO THERE FAULTY EQUIPMENT. WITH THE TEMPERATURE BEING EXTREMELY HOT I WOULD THINK MY CAR WOULD BLOW UP BECAUSE IT IS A BLACK CAR. ANY HELP WITH THIS MATTER IS APPRECIATED. MERCEDES OF SOUTH ATLANTA (SERVICE ADVISOR-TUTT) INFORMED ME TO PAY $2100 TO FIX. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).' *PM
ON 8/29/17 AROUND 11:20 - 11:30AM, I WAS DRIVING ON N270 JUST OFF FROM HOV LANE FROM S495 NEAR MONTROSE EXIT(LITTLE BIT BEFORE), SOME METALLIC ROUND WHEEL TYPE WITH SHARP EDGES AROUND FLEW OVER FROM S270. I TRIED TO AVOID IT BY SWERVE MY CAR BUT IT MUST HAVE LANDED BELOW MY CAR AND SCRATCHED UNDERNEATH WHICH CAUSED MY CAR MAKING WEIRD SOUND PLUS BURNING GASOLINE SMELL. I DIDN'T SEE MY TIRE PRESSURE GAZE CHANGE SO I WENT INTO LOCAL LANE FROM FALLS ROAD TO GET TO MY HOME. MY CAR WAS NOT STEERING PROPERLY AND I CAN SMELL GASOLINE EVEN FROM CLOSED WINDOWS. AFTER PARKING MY CAR, I SAW GASOLINE LEAKAGE FROM UNDERNEATH MY CAR. IT WAS SUCH SCARY INCIDENT AND I WAS SO LUCKY TO BE ALIVE AND NOT HURT WITH GASOLINE LEAKING FROM MY CAR.

I WAS ON A SNOW COVERED ROAD IN MY NEIGHBORHOOD DRIVING ABOUT 10-15 MPH AND ATTEMPTED TO MAKE A RIGHT TURN. THE CAR KEPT GOING STRAIGHT AND SLID OFF THE ROAD. THE ESP STABILITY CONTROL AND ABS FAILED TO OPERATE AT THAT POINT. THIS WAS AFTER A RECENT REPROGRAMMING BY THE DEALER. THIS FUNCTION HAD OPERATED CORRECTLY ALL WINTER PRIOR TO THAT EVENT. THE ESP LIGHT DID NOT FLASH LIKE IT NORMALLY DOES IN THAT SITUATION. THERE COULD HAVE BEEN A CAR COMING THE OTHER WAY AND I WOULD HAVE HIT THEM DUE TO THIS FAILURE. NO ERROR LIGHTS WERE DISPLAYED BY THE CAR. THE CAR GOT HUNG UP ON A BIG ROCK THAT WAS IN SOMEONE'S YARD AS A RESULT OF THE INCIDENT. I DID NOT REPORT TO THE POLICE SINCE IT WAS JUST ME AND NO APPARENT DAMAGE TO THE YARD, ONLY TO MY CAR UNDERNEATH. *TR
