| 5952 mi | Injectors (Delphi) failed. Mercedes will make a recall of this kind of injector installed in all the C220 and C250 Blue Efficiency models as soon as Delphi can produce them Injectors failed, under warranty, but Mercedes doesn't have enough injectors to fulfill all those c220 and c250 that are breaking down. I expect to have my car in 2 or 3 weeks. This is really sad...so much tests, and about40%of the Delphi injectors |

| 9000 mi | When the car is cold (first driven during the day and when it's cold outside), a minute after it's started and for about 2 minutes a squeak(1 sec separating) comes from what sounds like a belt pulley. It did this last winter too. |

When I bought this car, the infamous salesman at the Oakland dealership assured me it was a flex-fuel car. Now, in Minnesota where getting E85 is so easy, we tried to find engine light on. I am now told not all C300 are E85 ready. |
