AFTER STARTING UP THE CAR AND TURNING ON THE SEAT HEATERS WE NOTICED A STRONG BURNING SMELL. WE HAD JUST ENTERED A SLIP ROAD AND MY WIFE (WHO WAS DRIVING) FELT A BURNING IN HER LOWER LEFT SIDE. NEXT THING... SHE WAS ON FIRE! HER WINTER COAT BUST INTO FLAMES AND AFTER PULLING OVER I GRABBED HER OUT OF THE DRIVERS SEAT AND ROLLED HER IN THE SNOW TO EXTINGUISH THE FIRE, WE WERE AMAZED THAT THE SEAT HAD A LARGE BURN HOLE THROUGH THE LEATHER AND THAT THERE WASN'T ANY SAFETY SHUT OFF FOR THE SEAT HEATER INITIATED BY THE VEHICLE. AFTER A DETAILED DESCRIPTION TO THE SERVICE MANAGER AT THE LOCAL MERCEDES DEALERSHIP OF WHAT HAD HAPPENED,WE WERE TOLD THAT A $2578 REPAIR WOULD FIX THE PROBLEM... WE WERE AMAZED AT HOW UNCARING THEY WERE AND THAT THERE WASN'T A RECALL ACTIVE FOR THIS DEFECTIVE WIRING PROBLEM. WE WERE RELIEVED THAT THIS DIDN'T CAUSE ANY FATALITIES TO US OR ANY OTHER PEOPLE THAT COULD HAVE BEEN AFFECTED IF WE WOULD HAVE BEEN ON A FREEWAY AT A HIGHER SPEED.

FAULTY WIRING IN THE BRAKE LIGHT HARNESS THAT COULD CAUSE FIRE. WIRING COMMONLY ARCS CAUSING THE BULBS TO BURN OUT AND COULD POTENTIALLY CAUSE A FIRE. MERCEDES HAS OTHER CARS WITH THIS SAME PROBLEM, BUT WON'T ADDRESS IT ON THE ML350'S. THEY EVEN MADE A PART TO CORRECT THIS PROBLEM, BUT DEMAND CAR OWNERS PAY OUT OF POCKET TO FIX MERCEDES FAULTY WIRING PROBLEM.

NHTSA has issued a do-not-drive warning for a recall on this vehicle.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
