I WAS DRIVING IN MY SON [XXX] TO HIS SCHOOL IN WAYNE NEW JERSEY WITH MY GL 450 SEATS WARMER TURNED ON IN BOTH THE DRIVERS AND PASSENGER SEATS. I STARTED SMELLING SMOKE & THOUGHT IT WAS FROM OUTSIDE. I OPENED MY WINDOW, AND SMOKE STARTED SWIRLING INSIDE MY CAR AND STARTED GETTING THICKER WITHIN MINUTES. I TRY TO SEARCH FOR THE SOURCE OF THE STRANGE SMELL - BUT NO OBVIOUS CLUE OBSERVED. WHEN I REACHED MY DESTINATION I NOTICED THAT THE SEAT HAS BURNED A HOLE IN MY SUIT JACKET BACK LEFT SIDE. THE HOLE IN THE CAR IS ON THE LEFT SIDE OF THE DRIVERS SEAT. I HAVE NOT CONTACTED MERCEDES BENZ SERVICE AND WOULD LIKE TO KNOW WHAT I SHOULD DO IF POSSIBLE. I WOULD APPRECIATE DIRECTING ME TO THE APPROPRIATE LINE TO FIX MY SEAT AND ELECTRICAL SYSTEM OF MY JEEP AND GET COMPENSATED FOR MY SUIT DAMAGE ASAP. *TR

THE PLASTIC THAT HOLDS THE LATCH BROKE. WE NORMALLY HAVE A CHILD SEAT BUCKLED INTO THAT BELT. BUT WE WERE ON A TRIP, AND I WAS THE ONE USING THIS SEAT BELT. I COULD NOT LATCH IT, AND FOUND THAT A CHUNK OF THE PLASTIC HAD BROKEN AWAY FROM THE BELT AND WOULD NOT LATCH. MERCEDES AND MY EXTENDED PROTECTION PLAN WILL NOT REPLACE IT WITHOUT A COST. OF APPRX 170.00 I HAVE NEVER HAD AN ISSUE WITH A SAFETY DEVICE IN ANY VEHICLE THAT I HAVE OWNED, AND I BELIEVE THAT A CAR THAT COSTS OVER 80,000.00 WOULD WANT TO KNOW WHY IT HAS FAILED. I AM GRATEFUL THAT MY GRAND CHILD WAS NOT BUCKLED INTO THIS BELT! *JS
