2008 Mercedes-Benz C350 Problems

Internal Component Failure May Cause Rough Shifting

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Camshaft Adjuster Solenoid Failure

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Inside Grab Handles/Upholstery/Door Trim Panels May Delaminate

Inside grab handles, the upholstery on the center console cover, and door trim panels can delaminate. Most commonly replacement of the affected part is necessary.

We bought the C350 Sport Model brand new. Now it has about 76k miles. My wife loves loves loves this car. I like the exterior looks. The interior is nice too. Nav is just OK. Controls take a bit to get use to. Likes to eat rear brake pads. Over all I'd give it a 8.9 out of 10.
