MY ML320 VEHICLE WAS DRIVEN FOR APPROXIMATELY FIVE HOURS ROUND TRIP THEN PARKED FOR THE EVENING. I ATTEMPTED TO START THE VEHICLE THE FOLLOWING MORNING AND THE VEHICLE WOULD NOT START. AFTER DOING AN EXHAUSTIVE DIAGNOSTIC ON THE VEHICLE. I REMOVED THE FUEL PUMP FROM INSIDE THE FUEL TANK. I SAW THAT THE WIRING HARNESS/CONNECTOR FOR THE HOT LEAD WAS BLACK AND BROWN IN COLOR AND THE PLASTIC AROUND THE HARNESS HAD MELTED. I TOOK PICTURES AND STORED THE PUMP. I EMAILED MERCEDES AND ASKED THEM TO GET BACK WITH ME SINCE MY WIFE AND CHILDREN HAD BEEN IN THE VEHICLE AND THIS IS THE FAMILY VEHICLE. I ALSO READ SEVERAL FORUMS AND COMPLAINTS ON THE INTERNET REFERENCE MERCEDES FUEL PUMPS INCLUDING MY SPECIFIC MODEL. I READ HOW THEY HAVE CAUGHT ON FIRE. I ALSO SAW A PICTURE OF A FUEL PUMP OUT OF A ML 320 IN 2006 THAT HAD CAUGHT FIRE AND ALMOST LOOKED IDENTICAL TO MY FUEL PUMP I HAD REMOVED. I HAVE LOOKED FOR RECALLS AND STILL HAVE NOT HEARD BACK FROM MERCEDES. I AM AT A LOSS ON WHAT TO DO OR IF THERE IS ANYTHING I CAN DO. I WAS TOLD THAT MERCEDES KNOWS ABOUT THIS PROBLEM BUT THAT HEY ARE UNLIKELY TO DO ANYTHING BECAUSE OF THE COST. I WANT TO REPORT THIS IN CASE SOMETHING DOES HAPPEN TO ME AND MY FAMILY. IT WILL BE ON RECORD. THANK YOU FOR YOUR TIME. *TR
