The 2005 Mercedes-Benz C240 4Matic is a pretty reliable vehicle; there are typically only superficial issues, or the type of problems You'd expect in a vehicle this age, such as rust, dry rotted hoses, worn brake pads and the like. However, even with this reliability, there has been four recalls for this vehicle from Mercedes, though to addreSSRare or unlikely scenarios. The first is for the sun/moon roof assembly: a detached glass panel can separate from the vehicle and become a road hazard. There aren't any reports of this happening. Additionally, in a crash, the driver side inflator module for the air bag could rupture with metal fragments, striking the occupants and killing everyone. There haven't been any actual reports of this occurring, either. There's also an issue where the restraints aren't properly functioning during air bag deployment. Finally, during a crash, the fuel pump may not receive a crash signal, stopping it from continuing to pump. All in all, the recall scenarios are pretty unlikely, and this truly is a great vehicle.

There are not any specific issues with the 2005 mercedes c240, however due to the age of the vehicle it is likely there will be issues with the engine or transmission. Rust or damaged metal could have set in over time. Likewise the brake lines and other fluid lines should be checked for dry rot and leaks. Brake pads will likely need to be replaced and tires should be checked for age and rot. The oil and oil pump should be checked for rot on the lines, and cracks in the pan. There may also be dead or damaged wires and blown fuse causing electrical problems throughout the vehicle.
