Summary

The 2008 Mercedes-Benz C300, while a desirable vehicle, is prone to certain issues. The engine can suffer from camshaft adjuster solenoid problems and potentially more serious balance shaft wear, which can be quite expensive to repair. The 7G-Tronic transmission can experience torque converter and valve body issues, leading to drivability problems. Electrical glitches related to the EIS and SAM modules are also common. Suspension issues, such as control arm bushing failures, can affect handling and ride quality. These issues range in severity and cost, but potential buyers should be aware of these common problems before purchasing. Addressing these problems can be costly, which is common with a luxury vehicle such as Mercedes-Benz.
