2007 Mercedes Benz GL450

ON NOVEMBER 17, 2020, I TURNED MY DRIVER SEAT HEATER AND SUDDENLY SMELLED SOMETHING BURNING. AFTER SEVERAL MINUTES DRIVING I DECIDED TO TURN OF THE HEATER, THE BURNING SENSATION ON MY BACK WAS INTENSE. ONCE I PARKED, I NOTICED A HOLE IN MY SEAT THE SIZE OF A QUARTER! I CHECKED MY CLOTHING AND NOTICED IT MELTED THE ELASTIC PART AT THE BOTTOM MY JACKET.

RAIN LEAKED IN THROUGH THE BACK CAUSING THE REAR SAM TO BE FILLED WITH WATER. THIS CAUSED ALL OF MY TAILLIGHTS TO GO OUT. I SAW A RECALL FOR VEHICLES WITH THE SAME YEAR AS MINE BUT THERE IS NO RECALL FOR THE GL 450 THAT I CAN FIND. I CALLED MERCEDES WHICH YIELDED NOTHING.THEY TOLD ME THE RECALLS ARE VIN SPECIFIC, NOT VEHICLE SPECIFIC. I GUESS MY VIN WASN'T CHOSED EVEN THOUGH IT HAS THE SAME ISSUE AS THE ONES THEY RECALLED IN 2009. THIS IS A NEW SAM. IT WAS REPLACED BY US WHEN WE BOUGHT THE VEHICLE USED.

MY CAR BATTERY DIED, ROADSIDE ASSISTANCE JUMPED MY CAR, MECHANIC REPLACED MY BATTERIES. THE CAR STARTED WITHOUT PROBLEMS, BUT THEN A MESSAGE CAME UP IN MY DASHBOARD IN RED SAYING TO DRIVE THE CAR TO THE WORKSHOP WITHOUT SHIFTING GEARS; AFTER THE MECHANIC CHECKED THE CAR AND DID SOME RESEARCH HE FOUND THAT THE INTELLIGENT SERVO MODULE WAS BAD; THE CARD WOULD NOT SHIFT INTO GEAR. THE VEHICLE WAS STATIONARY WITH THE ENGINE RUNNING IN THE SHOP. *TR

TL* THE CONTACT OWNS A 2007 MERCEDES-BENZ GL450. THE CONTACT STATED THAT THE DRIVER'S SEAT HEATER BURNED THROUGH THE SEAT AND HER COAT. AN ABNORMAL BURNING ODOR WAS DETECTED AND FLAMES APPEARED. THE CONTACT EXTINGUISHED THE FIRE. THERE WERE NO INJURIES. THE VEHICLE WAS TAKEN TO EURO MOTORCARS BETHESDA (7020 ARLINGTON RD, BETHESDA, MD 20814, (301) 986-8800) WHERE IT WAS DIAGNOSED THAT THE SEAT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 83,000.

TL* THE CONTACT OWNS A 2007 MERCEDES-BENZ GL450. WHILE DRIVING VARIOUS SPEEDS, THE ABS INDICATOR ILLUMINATED AND REMAINED LIT. IN ADDITION, THE ESP AND CHECK ENGINE INDICATORS ALSO ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT ALL THE WHEELS NEEDED TO BE REPLACED AND REFERRED THE CONTACT TO THE DEALER .THE CONTACT CALLED MERCEDES-BENZ OF SOUTH ORLANDO AT 407-374-0033 (LOCATED AT 4301 MILLENIA BLVD, ORLANDO, FL 32839) AND WAS INFORMED THAT THE PARTS WERE ON BACKORDER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 190,000.

ON SEVERAL OCCASIONS THE ENGINE HAS SHUT DOWN WITHOUT WARNING. THIS HAS HAPPENED AT IDLE (STOPPED AT A RED LIGHT) AND WHEN TRAVELING 70+MPH ON THE INTERSTATE. THE EVENT HAPPENS VERY FAST AND THE ENGINE RESTARTS WITHIN 30SEC. THE WARNING LIGHTS ON THE DASHBOARD LIGHT UP LIKE A CHRISTMAS TREE BUT ALL SYSTEMS CONTINUE WORKING (AC, RADIO, ETC). I HAVE TAKEN IT TO 2 DIFFERENT MECHANICS AND NEITHER ONE HAS BEEN ABLE TO IDENTIFY THE PROBLEM. THIS HAS BEEN VERY SCARY AND MAKES ME FEEL UNSAFE DRIVING THIS VEHICLE.

WHILE DRIVING ON THE FREEWAY AT APPROXIMATELY 60 MPH, THE VEHICLE RANDOMLY SHUT-OFF WITH NO WARNINGS WHATSOEVER, INCLUDING ALL THE INTERNAL ELECTRONICS (E.G. NAVIGATION, DASHBOARD). AFTER 1 SECOND, THE VEHICLE RESTARTED ALL BY ITSELF. THE CLOCK INSIDE THE VEHICLE KEPT ON CIRCLING BACK AND FORTH AS IF SOME LIGHTNING HIT IT OR SOMETHING, AND IT WAS VERY SCARY, SINCE THERE WERE MANY CARS ON THE FREEWAY.

THE FOLLOWING CONDITION APPEARED WITHIN THE LAST COUPLE OF MONTHS. (I PUT A DATE OF 1/1/18, IN THE BOX BELOW, BUT THE PROBLEM HAS OCCURRED AT LEAST A DOZEN TIMES SINCE THEN, AND I FIND IT UNSAFE TO DRIVE THE VEHICLE ANY MORE). AT HIGHER SPEEDS, THE VEHICLE'S TRANSMISSION WILL DOWNSHIFT TO BY ITSELF INTO 1ST GEAR SUDDENLY AND WITHOUT WARNING. EVEN AT FREEWAY SPEEDS RPMS WILL SUDDENLY JUMP UP TO "RED-LINE" LIMITS AS THE DOWNSHIFT OCCURS FROM 7TH GEAR TO 1ST GEAR. THE VEHICLE MUST BE BROUGHT TO A COMPLETE STOP AND ENGINE MUST BE TURN OFF AND RESTARTED FOR TRANSMISSION TO ENGAGE PROPERLY. IT'S VERY DANGEROUS WHEN OTHER VEHICLES ARE FOLLOWING OR IN ADJACENT LANES TRAVELING AT HIGH SPEEDS. ALSO, AFTER DRIVING AT HIGHER SPEEDS, VEHICLE RPMS DROP SUDDENLY AND WITHOUT WARNING WHEN COMING TO A COMPLETE STOP. TRANSMISSION BASICALLY DISENGAGES AND WILL NOT RE-ENGAGE EVEN WHEN GAS PEDAL IS PRESSED. ENGINE MUST BE TURNED OFF COMPLETELY AND RESTARTED FOR TRANSMISSION TO ENGAGE. EQUALLY DANGEROUS CONDITION - ESPECIALLY WHEN DECELERATING ON FREEWAY OFF-RAMPS. THE VEHICLE HAS BEEN WELL MAINTAINED (ALL SERVICE RECORDS ARE AVAILABLE), AND I AM THE ORIGINAL OWNER (BOUGHT NEW IN LATE 2006). THE VEHICLE HAS BEEN DRIVEN APPROXIMATELY 117,500 MILES AS OF FEBRUARY 2018. WHAT ALARMS ME THE MOST IS THAT I HAVE SEEN MANY OTHER OWNERS OF THE SAME VEHICLE REPORT EXACTLY THE SAME DANGEROUS TRANSMISSION PROBLEM. EVEN MY INDEPENDENT MECHANICS SAYS ITS A WELL KNOWN PROBLEM. I SAY IT'S A DANGEROUS PROBLEM. I SHOULD KNOW, IN PART BECAUSE I HAVE BEEN REGISTERED TRAFFIC ENGINEER FOR OVER 39 YEARS, AND WAS A PAST RECIPIENT OF A NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION FELLOWSHIP IN HIGHWAY SAFETY.
