2006 Mercedes-Benz C350 Owner Complaints

At 9,000 miles my 2006 Mercedes C350 had to have a fuel pump replaced. It was out of warranty (low miles usage for 5 year old car) so I had to pay $900 for the repair. I could smell fuel everytime I filled the tank and the Mercedes dealer said the pump had to be replaced. I read about a recall of E350 models being recalled for the same reason with the same engine. I asked the dealer about this and they said mine was not part of the recall because it is a C class Mercedes. It has the same engine with the same problem and I think this should be looked into.

WHEN DRIVING MY '06 C350 WITH 48 THOUSAND MILES, YES 48K ON IT, THE TRANSMISSION SEEMS TO GO INTO A SAFE MODE. IT NORMALLY OCCURS WHEN DRIVING AT HIGHWAY SPEEDS AND HAVE TO SLOW DOWN GRADUALLY, THEN UPON ACCELERATION THE TRANSMISSION JUST REVS UP THE RPM WITH NO POWER. I'M AFRAID ME AND MY TWO CHILDREN WILL BE REAR-ENDED DUE TO THE LOSS OF POWER IN THE TRANSMISSION. I THEN TRY TO DRIVE IT TO THE NEXT EXIT, SHUT OFF THE ENGINE AND RESTART. THIS NORMALLY RESETS EVERYTHING TO NORMAL. BUT IT COULD OCCUR AGAIN MINUTES OR HOURS LATER WHICH IS NOW GETTING FRUSTRATING GIVEN THE CAR IS BARELY REACHING 50K MILES. SO THIS HAPPENS INTERMITTENTLY, UNEXPECTEDLY, AND WITH VARYING FREQUENCY. MERCEDES BENZ USA SHOULD HAVE A RECALL ON THIS AS WHEN I CALL THE DEALERSHIP THEY KNOW EXACTLY WHAT HAPPENED AND IT'S A VERY WELL-KNOW DEFECT THAT COSTS A CONSIDERABLE AMOUNT TO REPAIR. THIS CAR STARTED DOING IT AT 40K AND DOES IT OFTEN. I'VE NOTIFIED MY LAWYER BECAUSE I'M AFRAID IT COULD HAPPEN WITH A VEHICLE BEHIND ME AND THUS CAUSE AN UNEXPECTED REAR END IMPACT FROM ANOTHER DRIVER ON THE HIGHWAY.

BALANCE SHAFT ENGINE ISSUES, STRETCHED TIMING CHAIN, BALANCE SHAFT SPROCKETS. THERE WAS A CLASS ACTION LAWSUIT ABOUT THIS THAT NO ONE MADE US AWARE OF AND THE REPAIRS HAD TO BE COMPLETED BY MAY 13, 2015 TO BE PART OF THE CLASS ACTION. NOW, BECAUSE WE DROVE IT SO FEW MILES IN THE PAST, THE ISSUES HAVE JUST APPEARED. WE HAVE JUST 76,000 MILES ON IT AND WERE TOLD THAT THEY WOULD HAVE TO TAKE THE ENGINE APART TO REPLACE THE CAMSHAFT BEARINGS BECAUSE THEY HAVE WORN DUE TO THE OTHER ISSUES. ALONG WITH THAT WE NEEDED A NEW HEAD AND GASKET AND CAMSHAFT SOLENOIDS. THIS IS ESTIMATED TO COST US $10,000.00. WE OF COURSE AREN'T GOING TO DO THE REPAIRS NOW. THERE SHOULD HAVE BEEN A RECALL ON THIS SO PEOPLE LIKE US THAT DON'T DRIVE A LOT OF MILES DON'T GET RIPPED OFF. THIS IS A MERCEDES THAT SHOULD HAVE EASILY RUN FOR OVER 200,000 MILES. NOW IT'S JUNK.

IN JULY 2009, AFTER FILLING MY VEHICLE WITH GASOLINE (38,000 MILES), I DROVE HOME, PARKED MY VEHICLE IN MY GARAGE AND EXITED THE INTERIOR. AFTER EXITING, I SMELLED THE VERY STRONG ODOR OF GASOLINE EMITTING FROM, WHAT APPEARED THE REAR OF THE CAR. I DID NOT SEE ANY LEAKS OR ANY EVIDENCE OF FUEL, SO I WENT INSIDE MY HOUSE. SEVERAL HOURS LATER, I ENTERED MY GARAGE AND WAS IMMEDIATELY OVERWHELMED WITH THE FUMES OF GASOLINE. I CHECKED MY CAR AGAIN, BUT WAS UNABLE TO FIND ANY LEAKS. I THEN OPEN MY CAR DOOR AND THE FUMES WERE EVEN STRONGER. AFTER LOOKING AROUND, I NOTICED THE ODOR WAS COMING FROM UNDER THE REAR SEAT. FEARING AN EXPLOSION MAY OCCUR, I OPENED MY GARAGE DOORS AND CAR DOOR AND TURNED ON SEVERAL FANS TO "AIR-OUT" THE AREA. THE NEXT DAY, I DROVE TO THE DEALER AND EXPLAINED. THE SERVICE MANAGER SAID IT WAS A COMMON PROBLEM WITH MY YEAR AND MODEL AND SAID THE FUEL GASKETS WERE BAD ON TOP OF THE GAS TANK WHICH IS RIGHT UNDER THE BACK SEAT. HE EXPLAINED WHEN FILLING UP, THE SEALS LEAK, BECOME SATURATED WITH FUEL AND EVEN SATURATE THE BOTTOM SIDE OF THE SEAT. HE SAID IF I WANTED IT FIXED, IT WOULD BE AN ESTIMATED $500. HE ALSO SAID IF I DID NOT WANT TO PAY TO FIX IT, HE SUGGESTED I ONLY FILL MY TANK TO 3/4 SO THE SEALS WOULD NOT BECOME WET. I EXPLAINED TO HIM THAT MY CAR WAS STILL LIKE NEW WITH ONLY 38,000 MILES AND MBZ SHOULD FIX THE MANUFACTURER DEFECT AT NO CHARGE. HE REFUSED. I CONTINUE TO DEAL WITH THIS DANGEROUS, FAULTY ISSUE TODAY. MY CAR ONLY HAS 79,000 MILES ON IT AND THE PROBLEM CONTINUES TO GET WORSE. I NOTICED SEVERAL OTHERS HAVE THE SAME PROBLEM AND LAWSUITS HAVE BEEN FILED, HOWEVER, I DO NOT KNOW THEIR STATUS. CAN YOU PLEASE ASSIST ME WITH THIS DANGEROUS ISSUE. MY FAMILY AND I SUFFER FROM SEVERE HEADACHES EACH TIME THIS PROBLEM OCCURS. THANK YOU VERY MUCH.

FRONT RIGHT SPRING BROKE. THIS IS THE 2ND SPRING THAT HAS BROKEN IN LESS THAN A YEAR. THIS TIME THE BROKEN SPRING WAS RUBBING AGAINST MOVING PARTS AND SMOKING AT ONLY 5 MPH. IF THIS HAPPENED AT HIGHER SPEEDS, OR ON A CURVE, I SUSPECT IT COULD BE DANGEROUS. THERE ARE NUMEROUS REPORTS OF MERCEDES SPRINGS BREAKING ON VEHICLES WITH LESS THAN 50,000 MILES. THAT WOULD CERTAINLY INDICATE TO ME THAT EITHER THE DESIGN OR SPRINGS ARE DEFECTIVE. *TR

AROUND DECEMBER 2010 I BEGAN NOTICING THERE HAS BEEN A GAS SMELL FROM REAR WHEEL HOUSING AND REAR SEAT WHENEVER I FILL UP THE GAS TANK. I HAVE EXPERIENCED WITH VARIOUS FUEL LEVEL AND CONCLUDED THAT GAS SMELL STARTS WHEN GAS IS MORE THAN 3/4 FULL. I HAVE BEEN TRYING NOT TO FILL GAS MORE THAN 3/4 AND HAVE RECENTLY CHANGED A DELIVERY UNIT AND ALL THE SEALS, WHICH HAVE BEEN PROBLEMATIC AREAS FOR MANY MERCEDES. THE GAS SMELL DID NOT GO AWAY AND I DON'T FEEL SAFE DUE TO THE RISK OF FIRE IN ADDITION TO THE UNPLEASANT GAS SMELL IN THE CABIN. *TR
