MOMENTS LATER THE CABIN STARTED FILLING WITH SMOKE AND THE FUMES BECOME UNBEARABLE WHICH MADE US, MYSELF, HUSBAND AND OUR 1.5YR OLD COUGH. MY HUSBAND NOTICED HIS SEAT WAS HOTTER THAN USUAL, AND QUICKLY REALIZED IT WAS THE SEAT THE FUMES AND SMOKE WERE COMING FROM AND QUICKLY TURNED OFF THE HEATER. WE STOPPED THE CAR, JUMPED OUT, I GRABBED MY SON FROM THE BACK SEAT AND WE FOUND A BURNT HOLE IN THE DRIVER SEAT!!

2 COMPLAINTS -1 I WAS DRIVING W/OUT A COAT ON & TURNED THE DRIVERS SEAT HEATER ON. THEN I STARTED FEELING A SHARP, STINGING PAIN ON MY BACK AND STARTED SMELLING THE BURNING OF WHAT TURNED OUT TO BE THE SEAT. I ALMOST HAD AN ACCIDENT TRYING TO GET WHAT I THOUGHT WAS A STINGING OR BITING INSECT OFF MY BACK. ONCE I REALIZED IT WAS THE SEAT HEATER, I TURNED THE SEAT HEATER OFF, ONLY TO FIND I NOW HAVE A HOLE IN MY SEAT. IF MERCEDES KNOWS THEY HAVE THIS PROBLEM, AS I HAVE COME TO READ HERE, THEY SHOULD WARN PEOPLE NOT TO USE THE HEATERS TO AVOID AN ACCIDENT AND AVOID HAVING A HOLE IN THE SEAT OR REPLACE THE SEAT AND HEATER. #2 THE FRONT AIR SUSPENSION SHOCK CRASHED ON THE FRONT OF MY CAR. MY CAR SAT IN THE DEALERSHIP FOR OVER A MONTH WAITING FOR MERCEDES TO REENGINEER THE AIR SHOCK. FINALLY, THEY TOLD US TO BUY AN AFTERMARKET AND THEY WOULD INSTALL. SHORTLY THEREAFTER REAR OF THE CAR WOULDN'T LEVEL AND THEY SAID IT WAS THE COMPRESSOR SO THAT WAS REPLACED. BUT STILL THE REAR WAS UNEVEN SO THEY REPLACED BOTH REAR SHOCKS AND STILL THE CAR WOULDN'T LEVEL. THEN THEY HAD THE NERVE TO TELL ME IT WAS THE FRONT AFTERMARKET AND THEY NOW NEEDED TO BE REPLACED. AND THE DEALER TOLD ME THE CAR WAS A 2007 SO WHAT SHOULD I EXPECT. I STOPPED GOING TO THE DEALER AND INSTEAD TOOK IT TO A PRIVATE SHOP. THEY REPLACED A SENSOR FOR A MINIMAL CHARGE AND THE CAR HAS BEEN FINE SINCE.

WHILE DRIVING TO WORK THIS MORNING, I TURNED ON THE DRIVERS SIDE SEAT WARMER. LESS THAN THREE MINUTES LATER, I NOTICED A STRONG ODOR FOLLOWED BY A CONSIDERABLE AMOUNT OF SMOKE AND HEAT COMING FROM THE SIDE OF THE SEAT NEAREST THE DOOR. I FELT WHAT I THOUGHT WAS SOMETHING POKING ME IN THE LEFT REAR POCKET OF MY PANTS, AND BURNED THE BACK OF MY KNUCKLE CHECKING FOR THE SOURCE OF THE HEAT. I IMMEDIATELY SHUT OFF THE HEATER AND PULLED OFF AT THE FIRST SAFE LOCATION. I EXITED THE VEHICLE (A PALL OF SMOKE FOLLOWED ME) AND KNOCKED THE SMOKING EMBERS OUT OF THE VEHICLE (A HOLE LARGER THAN A QUARTER IS BURNED IN THE SEAT). I ALSO NOTICED A HOLE WAS BURNED THROUGH MY PANTS. APPARENTLY, I CAME VERY CLOSE TO SIGNIFICANT PERSONAL INJURY, NOT TO MENTION THE FACT OF POSSIBLE LOSS OF CONTROL OF THE VEHICLE. WE CALLED THE DEALER AND THEY SCHEDULED THE CAR FOR NEXT MONDAY. RESEARCHING INTO THE ISSUE, MINE IS NOT AN ISOLATED CASE AS THERE ARE MULTIPLE CLASS ACTION LAWSUITS AND COMPLAINTS WITH THE NHTSA. OBVIOUSLY, THESE SEATS ARE DEFECTIVE, MERCEDES IS AWARE, THE PASSENGER SEAT IS NEXT AND IS NOT SAFE.
