Over time, hoses, the radiator, and the water pump can degrade, leading to coolant leaks. This is a common issue for many vehicles of this age and can lead to overheating if not addressed. Estimated repair cost: $400 - $1,200.

Brake Pad and Rotor Wear

The C-Class, especially when driven enthusiastically, can wear brake pads and rotors at a moderate pace. Regular inspection is key to preventing rotor damage and ensuring safe stopping. Estimated repair cost: $300 - $700.

Oil Leaks (Valve Cover Gasket)

The valve cover gasket can degrade over time, leading to oil seeping into the spark plug wells or dripping onto exhaust components. This is a common wear item on many Mercedes-Benz models. Estimated repair cost: $300 - $600.
