Odometer Fraud. The contact purchased a 2007 Mercedes-Benz E350. The contact stated that while attempting to sell the vehicle to the dealer, the contact was informed that the Carfax History report indicated a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 113,192, however, the Carfax History Report listed the mileage at 257,710 on October 16, 2023.
Vehicle headlight burned out while driving at night time reduced visibility. Upon inspection found the headlight wires insulation located behind the passenger's light bulb connector melted/burnt causing short circuit. Temporary fixing it with an electrical tape.
I HAVE 2007 E350 CLASS 4-MATIC SPORT PACKAGE, THE PANORAMIC SUNROOF DOES NOT OPEN AND WHEN I PUSH BOTTOM TO OPEN THE MOTOR SOUND LIKE IS GRINDING THE CAR HAS ONLY 75000 MILES ON IT AND THE DEALER DOES NOT WARRANTY IT. THE COST TO HAVE REPAIRED AT MERCEDE DEALERSHIP IS $1500.
SPENT OVER $2K JUST ON DIAGNOSIS AND WRONG FIXES. IT STARTED WITH PROBLEMS CRANKING. I REPLACED THE KEY FOB, REPLACED THE BATTERY, REPLACED THE ALTERNATOR, HAVE HAD MERCEDES DIAGNOSE WITH NO ANSWERS. MY USUAL MECHANIC DIAGNOSE WITH NO ANSWERS. A EUROPEAN SPEACIALIST REPLACED THE ALTERNATOR AND TENSIONER PULLEY. TOOK IT TO A FRIEND AND WE DISCOVERED THAT THERE WAS A LEAK IN THE SUNROOF RUNNING DOWN THE SIDE OF THE CAR INTO THE BATTERY COMPARTMENT. AT THIS POINT VARIOUS PROBLEMS ARE GOING ON. THE WINDOWS, DOOR LOCKS, RADIO, CRANKING, ALL INTERMITTENT BUT NOT ALWAYS AT THE SAME TIME. TOOK IT TO ANOTHER MECHANIC WHO SAID THE SANS MODULE IS BAD, AT LEAST. AN $800 FIX, THEN THEY COULD MOVE TO THE NEXT MODULE AND THE NEXT. ALSO MAYBE UNRELATED BUT MAYBE NOT. LOW CAR LIGHT CAME ON. ENGINE 'DIED' (VEHICLE LOST ALL POWER) WHILE TRAVELING AT HIGHWAY SPEED OR WILL JERK DOWN GEARS AND ONLY CONTINUE TO FUNCTION IN DRIVE @ 40MPH OR LOWER. I HAD TO PULL VEHICLE OVER ON SIDE OF THE ROAD WITH NO POWER ASSISTANCE STEERING OR BRAKING. THIS PROBLEM OCCURRED WITH NO WARNING AND AT HIGHWAY SPEEDS CREATING AN IMMENSE SAFETY RISK. MANY OTHERS HAVE REPORTED THE SAME ISSUE WITH THIS AND RELATED CARS FOR THIS AND NEARBY MODEL YEARS. LIKE THEM, I WONDER WHY THERE IS NO RECALL. MERCEDES BENZ WILL NOT REPLACE THESE DEFECTIVE PARTS WILLINGLY AND THERE ARE MANY OF THESE CARS DRIVING DOWN OUR HIGHWAYS PLACING NOT ONLY THE PASSENGERS AT RISK BUT OTHER DRIVERS AROUND THEM.
MY CAR WAS RUNNING SUDDENLY STOP AND DOES NOT START, I TAKE IT TO MERCEDES DEALER AND THEY CHARGE ME $195.00 PLUS TAX TO SCANNED IT THEY FOUND THE ECM ENGINE CONTROL MODULE NEED TO BE REPLACE. COST IS $2,300 PLUS TAX. PLEASE CONTACT ME FOR AT YOUR CONVENIENCE SO I CAN TAKE FURTHER STEPS TOWARDS MERCEDES BENZ. *TR
TL* THE CONTACT OWNS A 2007 MERCEDES-BENZ E350. WHILE DRIVING VARIOUS SPEEDS, THE BATTERY WARNING INDICATOR ILLUMINATED. IN ADDITION, THE POWER STEERING BECAME DIFFICULT TO MANEUVER AND THE VEHICLE STALLED. ALSO, THE CHECK ENGINE WARNING INDICATOR REMAINED ILLUMINATED. THE CONTACT WAS UNABLE TO RESTART THE VEHICLE. THE VEHICLE WAS TOWED TO MERCEDES-BENZ OF WEST CHESTER (LOCATED AT 1260 WILMINGTON PIKE, WEST CHESTER, PA 19382, (484) 313-1100) WHERE IT WAS DIAGNOSED THAT THE FUEL PUMP NEEDED TO BE REPLACED. THE FUEL PUMP WAS REPLACED; HOWEVER, THE FAILURE RECURRED TWICE. ADDITIONALLY, THE FUEL PUMP FILER, WATER PUMP, TENSIONER PULLEY, AND SERPENTINE BELT (WHICH WAS REPLACED NINE TIMES) WERE REPLACED, BUT THE FAILURE RECURRED. THE CONTACT WAS ALSO INFORMED THAT THERE WAS AN ELECTRONIC FAILURE FOR WHICH THE MECHANIC WAS UNABLE TO REPAIR. THE CONTACT ALSO STATED THAT THE FUEL GAUGE AND COOLANT SYSTEM WERE INOPERABLE, AND THERE WAS A FAILURE WITH THE WATER PUMP. THE MANUFACTURER WAS INFORMED OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 129,000.
THE ENGINE STALLED WHILE IN MOTION AND DRIVING OVER 45 MPH. THIS IS THE 2ND TIME THIS HAS OCCURRED. BOTH TIMES I WAS TRAVELLING OVER 45 MPH ON A LARGE AND BUSY CITY STREET AND HAD DIFFICULTY STEERING MY CAR TO SAFETY. THERE ARE NO CODES TO EXPLAIN WHAT MIGHT BE THE CAUSE. REPLACED THE TRANSMISSION CONTROL UNIT THE FIRST TIME. AFTER REMOVING THE KEY, PUTTING THE CAR IN PARK AND WAITING FOR 5-10 MINUTES, IN BOTH OCCURRENCES I WAS ABLE TO RESTART THE VEHICLE AND DRIVE TO THE DEALERSHIP, WHICH WAS LESS THAN 5 MILES FROM MY LOCATION.
ON THE NTIGH OF APRIL 15, 2019, WHILE DRIVING ON A STREET IN ORLANDO, FL, THE WARNING THAT THE DRIVER SIDE LOW BEAM WAS OUT CAME ON. I REPLACED THE BULB THE NEXT DAY BUT THE NEW BULB LASTED ABOUT 20 MINUTES AND THE WARNING CAME ON AGAIN. THINKING I HAD A BAD BULB, ON APRIL 17, 2019, I WENT IN AGAIN TO REPLACE IT. THIS TIME I NOTICED A GOOD QUANTITY OF FRAGMENTS OF DRIED UP WIRE INSULATION INSIDE HEADLIGHT HOUSING AND NOTICED THAT THE 3 WIRES LEADING TO THE BULB WERE BARE. THE WIRES ARE SHORTING OUT, THE NEW BULB DID NOT LAST. I DID A BRIEF INTERNET SEARCH AND CONCLUDED THAT THIS IS A COMMON SAFETY PROBLEM WITH THE E350 AND MERCEDES IS AWARE OF IT. THE WIRING INSULATION IS NOT SUITED FOR THE JOB; IT IS FAILING; IT COULD CAUSE A FIRE OR A CRASH IF BOTH HEADLIGHTS GO OUT AT ONCE! THEREFORE I AM REPORTING THIS ISSUE AND EXPECT TO SEE MERCEDES STEPPING UP AND TAKING OWNERSHIP OF THIS PROBLEM.
THE WARNING LIGHT SAYING MY LOW BEAM BULB IS BLOWED. THE CAR WAS STATIONARY AT MOMENT. I HAD THE BULB REPLACED AND IT STILL DID NOT WORK. SO MECHANIC CHECKED AND SAW PIECES OF WIRE WITHIN THE HEADLIGHT CASING. ELECTRICAL WIRING TO MY HEADLIGHTS IS DISINTEGRATED. SO I ASSUME; THE COMPLETE WIRING THROUGHOUT THE ENGINE IS DISINTEGRATED. SO I BEGIN SEARCHING ONLINE AND READ THE ISSUE WITH MERCEDES USING FAULTY WIRING. THEREFORE; I AM REPORTING THE ISSUE AND WANT SOME TYPE OF SOLUTION.
30 AUG.16 TOOK MY 07 E350 WITH 29427 MILES TO THE DEALERSHIP BECAUSE THE CHECK ENGINE LIGHT CAME ON AND THE CAR WAS HARD STARTING. AFTER ARRIVING I INFORMED THE SERVICE WRITER THE CAR HAD SHUT DOWN WHILE DRIVING. WE WERE PROCEEDING THROUGH A BUSY MAJOR INTERSECTION WHEN THE CAR SHUT DOWN. LUCKILY IT STARTED SO WE COULD SAFELY EXIT THE BUSY MAJOR INTERSECTION. AFTER A DIAGNOSTIC TEST WAS RAN, I WAS INFORMED THE CRANKSHAFT HALL SENSOR WAS DEFECTIVE. ADDITIONALLY, THE ENGINE CONTROL UNIT, ENGINE WIRING HARNESS, CRANK SENSOR AND VARIOUS OTHER COMPONENTS ARE OIL SOAKED. I NOTIFIED MERCEDES BENZ TO BE TOLD THE CAR WAS OUT OF WARRANTY. MERCEDES BENZ SHOULD BE HELD ACCOUNTABLE FOR THE UNSAFE DEFECTIVE MATERIALS THEY USE. THE ABOVE ISSUES ARE A DANGER TO THE OCCUPANTS AND GENERAL PUBLIC AS WELL. THE DEFECTIVE OIL SOAKED WIRING HARNESS IS CAN CAUSE A FIRE. THE CAR SHUTS DOWN WHILE DRIVING IS DANGEROUS.
SUDDENLY THE VEHICLE TRUNK DOES NOT OPEN, TRIED BOTH REMOTE KEY & DOOR TRUNK LATCH. GOT A MESSAGE ON PANEL REGARDING 3RD BRAKE LIGHT..UNABLE TO GET THE WHEELCHAIR FROM TRUNK BUT DROVE CAR AROUND THE BLOCK AND WAS THEN ABLE TO OPEN IT USING MY KEY REMOTE. THEN A FEW MINUTES LATER AGAIN WAS NOT ABLE TO OPEN THE TRUNK, BUT NOW THE PANEL READ LICENSE PLATE RIGHT AND LEFT LIGHT LAMPS NOT WORKING...NIGHT DRIVING IS AN ISSUE NOW...CA LAWS REQUIRE LIC PLATE BE LIT AND VISIBLE AT ALL TIMES. I WENT ONLINE AND NOTICED ALL THE BUZZ AND COMPLAINTS REPORTING THIS SAME ISSUE REGARDING BROWN WIRE BEING SEVERED ON MANY MAKES, MODELS AND YEARS ON MER BENZ VEHICLES. I E-MAILED MB CUSTOMER SERVICE TO ASK ABOUT A RECALL AND THEY DO NOT HAVE ONE TO MY SURPRISE. GOT A CALL TODAY FROM [XXX] @ [XXX] STATING THERE IS NOTHING MB CAN DO SINCE MY WARRANTY HAS EXPIRED...I ADVISED HIM I HAVE UNDER 50K MILES ON THIS CAR, HE SAID THAT I WOULD NEED TO GET A DIAGNOSTIC TEST COSTING ME OVER $100 IN ORDER TO FIND OUT WHAT THE PROBLEM IS PLUS ACCORDING TO INTERNET COMMENTS THIS IS A $250 OR MORE REPAIR COST. I EXPLAINED MY INTERNET FINDINGS AND HE AGAIN APOLOGIZED, SAID THERE IS NOTHING HE CAN DO FOR ME. I EXPLAINED MY CONCERNS AND FEEL THAT MB SHOULD STEP UP AND TAKE RESPONSIBILITY IN GOOD FAITH AND GOOD CUSTOMER SERVICE AND FIX THIS ISSUE AT THEIR EXPENSE, OBVIOUSLY IT IS AN ELECTRICAL ISSUE MAL-FUNCTION AND THEY ARE RESPONSIBLE FOR FIXING THE PROBLEM AND SHOULD NOT PUT THIS BURDEN AND EXPENSE ON THEIR CUSTOMER'S. FRUSTRATED MB CUSTOMER *TR

MY WIFE WAS DRIVING WHEN SHE SMELLED SOMETHING BURNING AND THEN FELT SOMETHING BURNING, SHE PULLED OVER AND JUMPED OUT TO CHECK AND FOUND THE SEAT WARMER HAD MALFUNCTIONED AND BURNED THROUGH THE BACK PORTION OF THE SEAT. HER SHIRT HAD A SLIGHT BURN TO IT AND SMOKE COVERED INTERIOR OF THE CAR. THE HOLE IN THE SEAT IS ABOUT THE SIZE OF A CIGARETTE BURN BUT DEEPER. SHE TOOK IT TO THE IMPORT REPAIR SHOP WHO DISCONNECTED THE POWER SOURCE WIRE TO THE SEAT HEATER FOR SAFETY. *TR
I WAS USING THE WARMING SEATS AND HAD PULLED UP TO THE POST OFFICE TO DROP A LETTER IN THE BOX. THE LETTER HAD FALLEN TO THE GROUND. I GOT OUT AND PLACED THE LETTER IN THE BOX. I GOT BACK IN THE CAR AND PULLED UP TO KEEP FROM HOLDING UP TRAFFIC WHILE I HAD REPLACED MY SEAT BELT. A SUV HAD CROSSED MY PATH WHEN I SMELLED SOMETHING BURNING. I ASSUMED IT WAS EXHAUST FROM THE SUV. I WAS ABOUT TO PULL OFF THE PARKING LOT WHEN I NOTICED THICK WHITE SMOKING COMING FROM MY SEAT. I IMMEDIATELY TURNED OFF THE SEAT WARMER. THE SMOKE DISSIPATED AFTERWARDS.I CONTINUED TO DRIVE THE CAR ABOUT 1/2MILE TO THE GROCERY STORE. I GOT OUT AND NOTICED A BURN ON SEAT. *TR
I WAS DRIVING HOME FROM WORK ON A FREEWAY TRAVELING AT ABOUT 65MPH. ALL OF SUDDEN, MY CAR STARTING TO SLOW AND DECELERATED WHICH I PULLED MY EHICLE OVER TO THE EMERGENCY LANE WHERE IT STALLED. THE CAR WOULDN'T START AFTER THAT AND I CAN SMELL THE BURNING FROM THE UNDER THE HOOD. I GOT IT TOWED TO A MERCEDES SPECIALIST SHOP. THE SHOP REPORTED THAT THERE WAS A FIRE INSIDE THE AIR INTAKE MANIFOLD THAT CAUSED DAMAGE TO OTHER COMPONENTS AS WELL WHICH WAS VERY UNUSUAL. THIS MANIFOLD COMPONENT WAS ALL BURNED AND MELTED INSIDE INCLUDING OTHER SURROUNDING COMPONENTS. I CONSULTED WITH THE MERCEDES DEALERSHIP WHICH THEY STATED THIS NEVER HAPPEN TO ANY MERCEDES MODELS SO I THINK THIS IS A DEFECT AND A SAFETY HAZARD. THIS IS ONLY A 5 YEAR OLD CERTIFIED PRE-OWNED PURCHASE MADE FROM THE DEALER 3 YEARS AGO WHEN VEHICLE HAD ONLY 38,000 MILES ON IT. UNFORTUNATELY, MY WARRANTLY JUST EXPIRED 5 MONTHS AGO. AT THIS POINT, THE DAMAGE SO FAR EXCEEDED $4,000 TO REPAIR AND THE DEALERSHIP WON'T DO OFFER ANY GOODWILL REPAIR ON IT. LUCKILY FOR ME I WAS NOT INJURE FROM THIS INCIDENT BUT IT MAY NOT BE SO LUCKY IF IT HAPPEN TO SOMEONE ELSE. *TR
TURNED DRIVERS SEAT HEAT FEATURE ON, AFTER A FEW MINUTES I SMELLED BURNING. MERCEDES JUST REPAIRED A/C (3 VISITS) SO TURNED OFF THE A/C. NEXT THINK I KNOW SMOKE IS COMING FROM DRIVERS SEAT, MY 3YR OLD RIDING IN HER CAR SEAT "INSTALLED" BEHIND ME. HEATER IN DRIVERS SEAT WAS BURNING, WITH THE AIR NO LONGER BLOWING, SMOKE WAS NOW VISIBLE. I HAD TO CROSS 3 LANES OF TRAFFIC TO PULL OVER. THE "FIRE" BURNED A HOLE THROUGH THE LEATHER SEAT TO MY JEANS LEAVING ME A SLIGHT BURN. CAR TOWED TO MERCEDES. *TR
