SRS AND AIRBAG LIGHTS REMAIN ON. I WON'T BOTHER WITH THE DEALER BECAUSE I HAVE SEEN NUMEROUS COMPLAINTS ON VARIOUS BLOGS OF PEOPLE WITH THE SAME ISSUE WHO HAVE BEEN TOLD THAT THIS IS A $750 SENSOR THAT NEEDS TO BE REPLACED. MERCEDES SHOULD SEEK RECOURSE WITH THEIR SUPPLIERS AND STAND BEHIND THEIR "WORLD-CLASS GERMAN ENGINEERING" AND MAKE THEIR CUSTOMERS WHOLE. *TR

2004 ML 350 HAD SRS AND AIRBAG LIGHTS APPEAR ON DASH THAT DID NOT GO OUT DURING VEHICLE OPERATION. OWNER'S MANUAL STATED THIS COULD RESULT IN NO AIRBAG DEPLOYMENT DURING AN ACCIDENT, OR UNEXPECTED DEPLOYMENT OF AIRBAGS. I WENT TO THE DEALERSHIP AND WAS TOLD A SEAT RECOGNITION SENSOR WAS REQUIRED FOR $752. THIS IS A MAJOR SAFETY ISSUE AND IS A FAILURE OF A COMPONENT THAT SHOULD NOT FAIL, AND PLACE VEHICLE OCCUPANTS AT RISK, AFTER ONLY 3 1/2 YEARS OF OPERATION. MANUFACTURER SHOULD BE REQUIRED TO RECALL THESE VEHICLES AND TEST AND REPLACE THE SENSORS/MODULES OR RELATED PARTS. *TR

FRONT SEATS GETS VERY HOT WHENEVER WE TURN ON THE SEAT WARMER OPTION. THIS STARTED TO HAPPEN AT LEAST FROM 5 TO 6 MONTHS. WE ARE SCARED IT MIGHT BURN OUR BACKS. THANKS

May 16, 2019

I WAS DRIVING ON THE HIGHWAY AND THE HEATED SEAT WAS TURNED ON THE PASSENGER SIDE OF MY MERCEDES ML 500 WITH MY 17 DAUGHTER SITTING IN THE SEAT. THE CAR STARTED TO SMELL AND MY DAUGHTERS SEAT FELT HOT TO HER. SHE TRIED TO MOVE HER SELF OVER AND BURNT THE PALM OF HER HAND ON THE SIDE OF THE SEAT. THE HEATED SEAT HAD BEEN BURNING AT A VERY HOT TEMPERATURE AND WAS MELTING THE LEATHER ON THE SEAT. I IMMEDIATELY TURNED OFF THE SEAT AND OPENED THE WINDOWS TO HELP COOL IT OFF. IT TOOK 30 MINUTES OR MORE FOR THE SEAT TO COOL OFF IN THAT SPOT. MY DAUGHTER JUMPED TO THE BACK SEAT WHILE IT WAS STILL HOT SO THAT SHE WOULD NOT GET BURNED AGAIN. *TT

MAY 2010 I HAVE PROBLEM IN MY 2004 ML350. MY WIFE TURNED ON THE DRIVERS SIDE SEAT HEATER TO THE HIGH SETTING. WITHIN A SHORT TIME THE HEATER HAD BURNED THROUGH THE LEATHER SEAT. THE SEAT CAUGHT FIRE IN A SMALL SPOT ( LIKE A CIGARETTE BURN) WHILE MY WIFE WAS DRIVING AND ALMOST CAUSED HER TO HAVE AN ACCIDENT. THIS ISSUE IS REPEATED SEVERAL TIMES IN ONLINE SEARCHES I DID FOR THE 03 AND 04 ML350. I SPOKE TO A BENZ ROADSIDE ASSISTANCE MECHANIC AND HE SAID HE HAS SEEN THIS HAPPEN BEFORE AND THAT IT IS A SHORT IN THE SEAT WIRING. HE SAID HE WOULD LOOK INTO IT BUT I HAVE NOT HEARD BACK FROM HIM. I AM GOING TO CALL THE DEALER TODAY. *TR

May 27, 2010

Fire: 1

THE DRIVER SEAT HEATER OVER-HEATED AND CAUSED A MINOR BURN WHEN I TOOK THE CAR TO THE DEALER. THE DEALER AGREED TO PAY FOR HALF THE COST OF REPLACEMENT BUT WOULD NOT GIVE THE DEFECTIVE PART BACK TO ME EVEN WHEN I SPECIFICALLY ASKED FOR IT. WHILE SEARCHING FOR MORE INFORMATION, I CAME ACROSS OTHER INCIDENTS WITH THIS CAR WITH THE EXACT SAME PROBLEM. *TR

Apr 29, 2009

Injuries: 1

I HAVE A 2004 MERCEDES ML350 SUV AND I TURNED ON THE SEAT HEATER AND IT GOT SO HOT THAT I HAD TO TURN IT OFF. THE LEFT SIDE OF THE SEAT BURNED SO HOT THAT I HAD TO MOVE MY BODY AND WEIGHT TO MY RIGHT SIDE BECAUSE IT FELT LIKE YOU WERE SITTING ON COALS - EVEN THROUGH THE LEATHER INTERIOR. I DID NOT USE IT AGAIN BECAUSE THE WEATHER WAS NOT THAT COLD. THE NEXT PERSON TO USE IT WAS MY MOTHER. SHE WAS DRIVING MY CAR AND I WAS NEXT TO HER AND SHE TURNED ON HER SEAT HEATER AND AFTER A FEW MINUTES SHE SCREAMED BECAUSE THE HEAT OF THE SEAT HEATER WAS SO PIERCING. I TURNED OFF THE HEATER IMMEDIATELY AND SHE LOOKED AND SAW SMOKE AND SMELLED SMOKE AS WELL. THIS IS A HUGE HAZARD THAT I HAVE HEARD OTHER ML'S HAVE HAD AS WELL AND THE MANUFACTURER OF THE SEAT HEATER SHOULD BE HELD ACCOUNTABLE, AS SHOULD MERCEDES!!! SHE SWERVED OFF THE ROAD AND ALMOST HIT A CAR BECAUSE OF THE INTENSITY OF HEAT. *TR

DISCOVERED BRITTLE, BROKEN AND MISSING WIRING INSULATION ON THE HEADLIGHT WIRING INSIDE THE HEADLAMP ASSEMBLY. THIS WAS A DANGEROUS SITUATION THAT ALLOWED THE POSITIVE AND NEGATIVE WIRES TO COME IN CONTACT WITH EACH OTHER CREATING A SHORT.

Sep 18, 2017

DURING A ROUTINE CHANGE OF A HEADLIGHT LAMP, THE MAINTENANCE TECHNICIAN DISCOVER THAT THE INSULATION ON ALL FOUR WIRES IN THE LEFT FRONT HEADLIGHT ASSEMBLY WERE CRACKED, DISINTEGRATING AND MISSING LEAVING THE BARE WIRES EXPOSED. THE MAINTENANCE TECHNICIAN WOULD NOT CHANGE THE BULB UNTIL A NEW WIRING HARNESS WAS FABRICATED AND THE DISCREPANCY WAS CORRECTED. THIS IS A DANGEROUS SITUATION. THE BARE WIRES ARE IN AN ENCLOSED HEADLAMP ASSEMBLY, CONTACTING FLAMMABLE MATERIALS. A SHORT IN THESE WIRES CAN LEAD TO SYSTEM FAILURES, OVERHEATING AND FIRE IN THE HEADLAMP AREA. RECOMMEND A RECALL FOR INSPECTION AND IF THIS DISCREPANCY IS DISCOVERED, RECOMMEND AN IMMEDIATE REPLACEMENT OF THE WIRES IN THE HEADLAMP ASSEMBLY.

Feb 21, 2016

DURING REGULAR VEHICLE USE THE FRONT RIGHT HEADLIGHT STOPPED WORKING. UPON INSPECTION IT WAS FOUND THAT THE HEADLIGHT HOLDER HAD MELTED UNDER EXTREME TEMPERATURES DUE TO A MANUFACTURERS DEFECT IN THE WIRING HARNESS. *TR

WHILE DRIVING 2004 MERCEDES BENZ ML350 ON PUBLIC STREET THE ENGINE LOST ALL POWER WHILE MOVING AT 30 - 35 MPH. LOST BOTH POWER STEERING CONTROL AND POWER BRAKING ABILITY AS A RESULT. WAS ABLE TO AVOID COLLISIONS AND COASTED INTO AN OFF STREET AREA SAFELY. UNDER OTHER CIRCUMSTANCES ( HIGH SPEED FREEWAY TRAVEL ) ACCIDENT MAY HAVE BEEN CERTAIN. CAUSE DETERMINED TO BE FAULTY CRANK SENSOR. THIS SEEMS TO BE COMMON PROBLEM WITH THIS VINTAGE VEHICLE AND CAME AS NO SURPRISE TO MY MECHANIC. THIS IS ONE OF THE MORE FRIGHTENING DRIVING EXPERIENCES THAT I'VE HAD AND AM GRATEFUL THAT IT DID NOT OCCUR WHEN MY SPOUSE WAS DRIVING THIS VEHICLE; SHE WOULD HAVE HAD NO IDEA WHAT WAS HAPPENING OR WHAT TO DO. PLEASE LOOK INTO THIS PROBLEM. IF IT DOESN'T FALL UNDER THE CLASSIFICATION OF A TRANSPORTATION SAFETY ISSUE THEN THE DOT NEEDS TO REEVALUATE WHAT ITS MISSION IS. *TR

OEM jack failed without warning. No injuries but it could have been bad. Car got stuck and spinning wheels dug into a region of hard packed snow over a gravel driveway at my father's house. I was using the jack to lift the wheels out of their holes so I could fill the hole with chunks of wood. To spread the load on the snow the base of the jack was on a roughly 10" long piece of 2x4, which was placed on a roughly 8x10 inch piece of plywood. Jack worked fine for the first 2 wheels. On the 3rd wheel the "thrust washer" that transfers force from the nut that rides on the main screw, to the hinged arm which picks up the car, split in half without warning. This resulted in a sudden and complete failure of the jack, dropping the car back to it's starting position.

A WOMAN RAN A RED LIGHT AND CRASHED INTO THE FRONT PASSENGER SIDE OF MY 2004 MERCEDES BENZ ML 350. AFTER THE IMPACT THERE WAS SMOKE COMING FROM UNDER THE HOOD. A DRIVER COMING FROM THE OPPOSITE DIRECTION YELLED OUT THAT MY CAR WAS ON FIRE. WHEN I GOT OUT OF THE CAR, I SAW A BIG PUDDLE UNDER THE CAR AND IT IGNITED. WITHIN A FEW MINUTES THE CAR WAS COMPLETELY ENGULFED IN FLAMES. WHEN THE POLICE ARRIVED THEY DETERMINED FROM THE AMOUNT OF FRONT END DAMAGE TO THE OTHER CAR THAT THE DRIVER WAS NOT SPEEDING AND THAT THE IMPACT DIDN'T SEEM TO BE SUFFICIENT TO CAUSE MY CAR TO CATCH FIRE.

Hello my check engine light is on in my 2004 Mercedes ml350 so I took it to a Mercedes dealership for inspection and repairs. They kept my suv for 8 days and finally called me back and said they believe the check engine light is on because I need to replace my charcoal canister shut off valve. Now this component takes the gas vapors that has not been burned off and reroutes it through the charcoal canister and back into the engine so it can be burnt off and not enter the atmosphere and enter the inside of the vehicle. Well My suv has failed inspection for emissions and that’s why I brought it in to Mercedes. Well the service department at Mercedes called me 8 days later and said Mercedes does not make that part anymore. And no other aftermarket company makes it either. They charged me $200 to tell me they can’t fix it because the part is not made anymore. So am I safe ? Why Mercedes never recalled a vehicle that can not pass states emissions test. I wrote a letter to the head of Mercedes in Europe and the United States. They offered me $2,000 off of a new Mercedes or $1,000 off a Pre owned Mercedes. Sounds like they know something is not right here. So my complaint is can a car manufacturer stop producing a part that is needed to safely pass the emissions test and isn’t these fumes harmful to me and my family?

CAR SUDDENLY DEVELOPED EXTREME GASOLINE ODOR AFTER A BRIEF 20 MILE TRIP. CURSORY CHECK DID NOT IDENTIFY SOURCE. UPON RETURN TRIP, SAME EXTREME SICKENING ODOR RETURNED. UPON PULLING INTO GARAGE GASOLINE WAS VISIBLY POURING FROM UNDERNEATH THE CAR AND POOLING ON GROUND. IT LOOKED TO BE COMING DIRECTLY FROM GAS TANK AREA BUT COULD NOT DETERMINE MAIN SOURCE AS IT WAS SPRAYED THROUGHOUT THE UNDERCARRIAGE. ASIDE FROM THE NAUSEA, THIS CLEARLY POSED A SIGNIFICANT FIRE DANGER AND WAS IMMEDIATELY TRANSPORTED TO THE DEALER AWAITING REPAIR COSTS NOW. THERE HAVE BEEN NO OTHER INCIDENTS OR EXTERNAL REASONS THAT MIGHT HAVE LED TO THIS (SUCH AS RUNNING OVER SOMETHING OR HITTING SOMETHING IN THE ROAD). AFTER DOING RESEARCH THIS APPEARS TO BE THE SAME TYPE OF PROBLEM THAT HAS BEEN, AND CONTINUES TO BE EXPERIENCED BY OTHER OWNERS DUE TO A MANUFACTURING DEFECT.

WHILE DRIVING A MERCEDES ML350 ON THE ROAD, THE ENGINE TURNED OFF. I COASTED TO A STOP ON THE SHOULDER OF THE ROAD. WHEN I TRIED TO RESTART, THE STARTER CRANKED BUT THE ENGINE WOULD NOT START. WHEN I TRIED AGAIN AN HOUR LATER, THE ENGINE STARTED NORMALLY. THIS HAPPENED AGAIN, LATER IN THE DAY. IF I HAD BEEN ON A FREEWAY, IT WOULD HAVE BEEN QUITE DANGEROUS. I TOOK THE CAR TO A MERCEDES MECHANIC WHO IMMEDIATELY KNEW WHAT WAS WRONG AND HE REPLACED THE CRANKSHAFT POSITION SENSOR. HE SAID THAT THIS FREQUENTLY HAPPENS WITH THE ML350. *TR

WHILE DRIVING MY 2005 MERCEDES BENZ 350 ALONG ROUTE 1 IN NEW JERSEY, WITHOUT HEARING OR FEELING ANYTHING, MY GAS TANK WAS PUNCTURED. WHEN I STOPPED I SAW A PUDDLE UNDER THE CAR AND FOUND THAT THERE WAS A STEADY FLOW OF GAS FROM UNDER MY CAR. THE FIRE DEPARATMENT CAME AND THE CAR WAS TOWED AWAY. THE ENTIRE GAS TANK WAS REPLACED AT MY EXPENSE SINCE MERCEDES BENZ CLAIMS THAT FUEL TANKS ARE NOT THE SUBJECT OF ANY WARRANTY AND IF THEY ARE PUNCTURED IT IS NOT THEIR RESPONSIBILITY. I FIND IT HARD TO BELIEVE THAT AN OEM IS NOT RESPONSIBLE TO ENSURE THAT THEIR FUEL TANKS DO NOT SPRING LEAKS DURING NORMAL DRIVING CONDITIONS. I WAS EXTREMELY FORTUNATE THAT NO ONE DECIDED TO TOSS A LIT MATCH OR CIGARETTE OUT THEIR WINDOW AS I DROVE BY WITH GAS LEAKING OUT OF THE BOTTOM OF MY CAR. I HAVE ASKED THE DEALER WHO FIXED THE CAR TO SAVE THE DEFECTIVE TANK AND IT CAN BE SENT TO YOU UPON YOUR REQUEST.

I WANT TO PROTEST IN THE LOUDEST VOICE THAT I HAVE AS A AUTOMOBILE DRIVER THE USE BY SOME RECENT MODEL CARS OF HIGH INTENSITY HEADLIGHTS. I AM NOT REFERRING TO HIGH BEAMS.......THESE LIGHTS ARE FAR WORSE THAN HIGH BEAMS. I AM BLINDED BY THESE LIGHTS AND FIND MY EYES TURNING TO THEM INVOLUNTARILY. I FEAR THAT THEY WILL BE RESPONSIBLE FOR MANY ACCIDENTS IF OTHER DRIVERS REACT AS I DO. I SEE ABSOLUTELY NO NEED FOR SUCH LIGHTS ON OUR HIGHWAYS. THIS IS THE FIRST COMPLIANT I HAVE EVER SUBMITTED IN 57 YEARS OF DRIVING! *AK
