Mercedes-Benz R350 Problems

Problem With Ball Joints May Cause Creaking Noise

A problem with the ball joints can cause a creaking noise. There is an updated part to remedy this problem.

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.

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.

I purchased this car about 1 month ago at a very good price. I read consumer postings regarding the relative issues and decided for the price it was worth the headache.
