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!!

THE ISM (INTELLIGENT SERVO MODULE) HAS FAILED IN MANY OF THE SIMILAR MERCEDES CARS THAT I OWN. I CAN NOT START THE CAR AND CAN NOT EVEN ORDER THIS PART BECAUSE ONLY A DEALER CAN INSTALL THIS PART. MY VEHICLE IS STUCK IN A PARKING LOT AND THERE IS NOTHING I CAN DO. I THINK THIS ISSUE NEEDS TO BE RECALLED.
