CHECK ENGINE LIGHT CAME ON. TOOK THE VEHICLE TO THE LOCAL DEALER AND THEY FOUND CODES 1200, 1208, P0016 AND P0017. WORN BALANCE SHAFT SPROCKET. DOING RESEARCH ONLINE TURNS OUT THERE ARE HUNDREDS AND HUNDREDS OF AFFECTED MB CUSTOMERS. MERCEDES KNEW OF THIS PROBLEM AS EARLY AS 2007 BUT HAS NOT PUBLICLY ADDRESSED THIS ISSUE OR ISSUED A RECALL. THE BILL TO FIX THIS ISSUE IS OVER $4,000, SOME PEOPLE REPORT THE DEALER QUOTING THEM OVER $10,000. MY PRICE TO FIX THIS IS $5,995. MY COMPLAINT IS THAT THIS IS A KNOWN ISSUE BY MERCEDES. KNOWINGLY THEY INSTALLED, AND KEPT INSTALLING, PARTS THAT WEAR OUT PREMATURELY LEAVING CUSTOMERS WITH AN UNFAIRLY LARGE BILL TO CORRECT THEIR MISTAKE. *TR

THE ABOVE DATE IS AN ESTIMATE: TRANSMISSION SLIPS CAUSING CAR TO STALL AND ALMOST GOT REAR-ENDED. TOOK CAR THAT WAS UNDER WARRANTY TO DEALERSHIP AND THEY COULD NOT FIND AN ISSUE WITH TRANSMISSION. PROBLEM HAVE GOTTEN WORST. GOOGLED ISSUE AND FOUND A LOT OF COMPLAINTS ABOUT THE SAME ISSUE. THE MORE SERIOUS PROBLEM IS MY CAR REEKS WITH THE SMELL OF GASOLINE. TOOK CAR TO SAME DEALER AND THEY SAID THEY FIXED THE PROBLEM BUT MY CAR STILL SMELL OF GASOLINE. I ACTUALLY GET NAUSEA WHEN DRIVING AND EYES BEGAN TO BURN. IF I WAS A SMOKER, I WOULD BE AFRAID TO LIGHT A CIGARETTE IN MY CAR. MY GARAGE ALSO SMELL OF GASOLINE WHEN I PARK. WSBTV IN ATLANTA DID A SERIES ON THIS ISSUE LAST MONTH BECAUSE OF THE MANY COMPLAINTS. SOMEONE WILL BE INJURED OR KILLED IF THESE ISSUES IS NOT ADDRESS. DEALER IS MERCEDES BENZ OF SOUTH ATLANTA. *TR

WHILE ENTERING THE FREEWAY, THE TRANSMISSION DISENGAGED AND FAILED. THE VEHICLE WAS STEERED TO THE SHOULDER. THE DASH LIGHTS ALL CHANGED TO RED AND THE TRANSMISSION WOULD NOT ENGAGE. AFTER SHUTTING OFF THE ENGINE AND RESTARTING THE VEHICLE, IT PERFORMED NORMALLY UNTIL LAST WEEK. THE SAME FAILURE OCCURRED THREE TIMES LAST WEEK. AFTER RESTARTING THE ENGINE THE CAR WAS TAKEN TO THE CLOSEST NON-DEALER SERVICE CENTER AND A RESET OF THE TRANSMISSION SPEED SENSOR WAS PERFORMED ELECTRONICALLY. I WAS ADVISED THAT THIS IS A COMMON PROBLEM WITH MODEL AND THAT I WOULD NEED A NEW SET OF VALVES, SENSORS, SEALS ETC. *TR

I BOUGHT THIS CAR ABOUT 4 MONTHS AGO. THIS CAR HAS BEEN SERVICED RELIGIOUSLY AT THE LOCAL MERCEDES DEALER AND THERE HAS BEEN "NO KNOW PROBLEMS". ON A THURSDAY I NOTICED THE CAR SHIFTING A LITTLE FUNNY SO I HAD MY HUSBAND DRIVE IT JUST TO BE SURE. HE NOTICED THE SAME ERRATIC SHIFTING. ON SATURDAY I DROPPED THE CAR OFF AT THE MERCEDES DEALER (SAME DEALER IT HAS ALWAYS BEEN SERVICED AT). WHEN I PARKED THE CAR I WANTED TO CHECK EACH GEAR JUST TO MAKE SURE AND WHAT DO YOU KNOW...IT WOULD NOT SHIFT INTO REVERSE. LATER THAT DAY I HAD TO CALL MERCEDES TO FIND OUT WHAT WAS GOING ON WITH THE CAR AND THEY PROCEEDED TO TELL ME THE CAR HAD METAL SHAVINGS IN THE TRANSMISSION PAN AND WOULD NEED A NEW TRANSMISSION. THE QUOTE FOR A NEW TRANSMISSION IS $5800!!! I DON'T UNDERSTAND HOW THE CAR DID NOT GIVE ME ANY WARNING NOR AN INDICATOR LIGHT. THE CAR ONLY HAS 60K MILES ON IT AND IN NO WAY SHOULD NEED A NEW TRANSMISSION. ALSO, KEEP IN MIND THE TRANSMISSION WAS SERVICED AT THIS SAME MERCEDES DEALER AT 39K MILES. SOMETHING IS NOT RIGHT AND I WANT ANSWERS. I AM COMPLETELY SHOCKED AND SO UPSET. *TR

WHEN ACCELERATING FROM A STOP LIGHT, THE CAR WOULD NOT SHIFT GEARS AUTOMATICALLY. THE CAR SEEMS TO BE STUCK IN 1ST GEAR OR NEUTRAL AS I COULD NOT GET PAST 20MPH WITHOUT MAXING OUT MY RPM'S. I HAD TO DRIVE 3 MILES GOING 20MPH TO GET SOMEWHERE SO I COULD GET TOWED. AFTER TOWED TO THE DEALERSHIP, THEY COULD NOT REPLICATE THE SITUATION. THIS HAS HAPPENED TWICE WITHIN A WEEK'S TIME. THIS IS A MERCEDES 2007 E350. I HAVE SEEN OTHER POSTS ABOUT THIS EXACT SAME THING WITH NO SOLUTION. THE DEALERSHIP SAID TO PULL OVER AND RESTART THE CAR. WHAT!!! WHAT KIND OF FIX IS THAT? I DO THAT TO MY HOME PC...I SHOULDN'T HAVE TO DO THAT FOR MY CAR! I BOUGHT THIS CAR LESS THAN 30 DAYS AGO...AND THE DEALERSHIP DOESN'T SEEM TO WANT ANY PART OF IT.

NO WARNING OF ANY KIND, NOR ANY EVENT OF ANY KIND. ONE MINUTE, EVERYTHING IS FINE. THE NEXT, THE TRANSMISSION FAILS. TRANSMISSION FAILURE HAS HAPPENED 3 TIMES IN THE PAST 10 MONTHS. CAR IS A 2007 MERCEDES. ON ALL 3 OCCASIONS, I WAS DRIVING ON MULTIPLE LANE INTERSTATE. ONE 2 OF THE INCIDENTS, THE CAR SUDDENLY WENT OUT OF THE DRIVE GEAR INTO WHAT FELT LIKE NEUTRAL. IT STAYED THERE FOR 10 OR 15 SECONDS AND THEN RESUMED IN DRIVE ON IT'S OWN. POSSIBLE CONSEQUENCES OF VERY SERIOUS ACCIDENT. ON THE 3RD INCIDENT, I WAS AT A STOPLIGHT AND WHEN STARTING ON THE GREEN LIGHT, THE CAR WOULD NOT COME OUT OF 1ST GEAR. JUST DROPPED CAR OFF TODAY FOR THIS AND DON'T KNOW RESULTS YET. WHAT WAS DONE TO CORRECT: ON BOTH OF THE FIRST 2 OCCASIONS, SOFTWARE WAS UPDATED. THERE WERE OTHER THINGS DONE WHICH BIZARRELY SOMEHOW RELATE TO THE TRANSMISSION. I HAVE NO PARTS. I BELIEVE I DO HAVE THE SERVICE SHEET FROM BOTH OF THE EARLIER INCIDENTS. *TR

1EA13003 · Fuel Leakage From The Fuel Tank
Opened Mar 15, 2013 · Closed Dec 19, 2014
Status: closed (inferred from source dates) · Fuel System, Gasoline; Fuel System, Gasoline:delivery; Fuel System, Gasoline:delivery:fuel Pump; Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings; Fuel System, Gasoline:storage; Fuel System, Gasoline:storage:tank Assembly
The Office of Defects Investigation (ODI) opened this investigation on January 23, 2012 as PE12-001 based on 20 consumer reports in model year (MY) 2003-2006 E55 AMG vehicles.Based on new reports in other E-Class vehicles, ODI upgraded the investigation to Engineering Analysis (EA) 13-003 on March 15, 2013, and expanded the scope to all E-Class vehicles through MY 2008.The complainants alleged a strong odor of gasoline fuel both inside and outside of their vehicle, particularly after refilling the fuel tank.Many of the complainants noted that the odor subsided or went away after driving some distance thereby lowering the fuel level in the tank.Other owners reported they would only fill the tank to about three quarters full to avoid the odor altogether.Some complainants alleged fuel leaked from the fuel filter/sender, located on the top of the fuel tank on the driver's side, and collected on top of the tank.There were also allegations that the fuel leaks were associated with an Emissions Recall Campaign (No. 2008020001) conducted by Mercedes-Benz USA, LLC (Mercedes) in 2008 on MY 2003-2006 E-Class and CLS-Class AMG models.The issue in the recall involved small cracks in the pressurized outlet fitting of the fuel filter/sender.AMG vehicles are high performance models that operate at higher fuel pressure and use a different fuel filter/sender and fuel pump than non-AMG models.Information on Recall No. 2008020001 is available from the U.S. Environmental Protection Agency (EPA) website at www.EPA.gov.ODI's investigation found various leak sources that are unrelated to the outlet fitting cited in the EPA recall campaign.Through interviews with complainants, field inspections of complaint vehicles, and the collection and laboratory analysis of failed parts, three identifiable leak sources were found.The component parts and areas of the leaks involve the On-Board Diagnostic fuel tank pressure sensor (located on top of the fuel filter/sender), the outlet of the centrally mounted fuel tank fuel filling limiter valve, and the top of the fuel pump. These areas of leakage are located at the top of the fuel tank in unpressurized parts of the fuel system. When the tank is full, fuel can slowly weep/seep from micro-cracks in these components and may collect in cavities on top of the filter/sender, pump, or tank.Contrary to complainant's allegations that fuel entered the inside of their vehicle under the rear seat bench, neither ODI nor Mercedes found a plausible way for this to occur.The fuel tank is located outside of the passenger compartment, attached to the underside of the vehicle.The service access ports for the fuel filter/sender (driver's side) and fuel pump (passenger's side) are located under the rear seat bench, covered by a steel plate, sealed and bolted to the vehicle floor.When technicians service the fuel filter/sender, which has a regularly scheduled 60,000 mile service interval, and/or the fuel pump, the work is performed from inside the vehicle by working through the access ports.By letter dated September 4, 2014, Mercedes has notified the agency that it will extend the original warranty coverage to 15 years and unlimited mileage on Covered Fuel Tank Components in E-Class vehicles in MY 2003-2009 and CLS-Class vehicles in MY 2006-2011.The covered fuel tank components for the warranty extension include the fuel tank, fuel filter/sender, fuel pump, and all related gaskets/seals and retention rings.ODI is closing this investigation based on the manufacturer's extend warranty of the affected fuel system components and in consideration that the nature of the leaks does not appear to present an un

The Office of Defects Investigation (ODI) opened this investigation on January 23, 2012 as PE12-001 based on 20 consumer reports in model year (MY) 2003-2006 E55 AMG vehicles.Based on new reports in other E-Class vehicles, ODI upgraded the investigation to Engineering Analysis (EA) 13-003 on March 15, 2013, and expanded the scope to all E-Class vehicles through MY 2008.The complainants alleged a strong odor of gasoline fuel both inside and outside of their vehicle, particularly after refilling the fuel tank.Many of the complainants noted that the odor subsided or went away after driving some distance thereby lowering the fuel level in the tank.Other owners reported they would only fill the tank to about three quarters full to avoid the odor altogether.Some complainants alleged fuel leaked from the fuel filter/sender, located on the top of the fuel tank on the driver's side, and collected on top of the tank.There were also allegations that the fuel leaks were associated with an Emissions Recall Campaign (No. 2008020001) conducted by Mercedes-Benz USA, LLC (Mercedes) in 2008 on MY 2003-2006 E-Class and CLS-Class AMG models.The issue in the recall involved small cracks in the pressurized outlet fitting of the fuel filter/sender.AMG vehicles are high performance models that operate at higher fuel pressure and use a different fuel filter/sender and fuel pump than non-AMG models.Information on Recall No. 2008020001 is available from the U.S. Environmental Protection Agency (EPA) website at www.EPA.gov.ODI's investigation found various leak sources that are unrelated to the outlet fitting cited in the EPA recall campaign.Through interviews with complainants, field inspections of complaint vehicles, and the collection and laboratory analysis of failed parts, three identifiable leak sources were found.The component parts and areas of the leaks involve the On-Board Diagnostic fuel tank pressure sensor (located on top of the fuel filter/sender), the outlet of the centrally mounted fuel tank fuel filling limiter valve, and the top of the fuel pump. These areas of leakage are located at the top of the fuel tank in unpressurized parts of the fuel system.
