2006 Mercedes-Benz C350 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.

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
