Fuel/propulsion system
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…
