One problem related to radiator has been reported for the 2007 Mercedes Benz C280. The most recently reported issues are listed below.
I took delivery of a new 2007 Mercedes Benz C280 4matic vehicle the 1st week of January,2007 & on January 14, 2007 I was returning home on a us highway in seminole county, oklahoma when I approached a small (8 inches tall) house cat or possum & was unable to avoid running over the animal. Rather than the animal making contact with the "skid (protective) plate" & falling to the pavement, the animal busted through the plate & entered into the radiator fan unit doing extensive damage (approximately $3000). Upon inspection, it was determined that the "skid plate" was a thin plastic covering not capable of deflecting the impact of an object, but rather allowing the object to enter the engine cavity. I would request that a study be done to determine if this plate meets the industry standards.
