Mercedes-Benz E350 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz E350

Mercedes-Benz E350 Problems

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.

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.

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Due to a manufacturing defect, a crack can develop on the fuel filter when the vehicle is operated in high temperatures. This crack can result in a fuel leak, increasing the risk of a fire. Dealers will replace the fuel filter to correct this concern.

Certain vehicles were assembled with a right side window curtain airbag that was stitched together improperly. In the event of a crash, this airbag may deflate more quickly than intended, reducing the protection it may provide to vehicle occupants. Mercedes-Benz dealers will replace the right side window curtain air bag on affected vehicles to correct this concern.

Forty-one vehicles may have a front engine pulley that was manufactured with an insufficient adhesive where the inner mass damper ring attaches to the vibration damper. If the inner ring were to separate with the hood open and the engine running, personal injury could result. Dealers will inspect and replace the affected parts to correct this issue. This recall is expected to begin during April of 2011.

I have a 2006 E350 and need a Schedule C Maintenance Check-up. After consulting the owner's manual, it is difficult to determine exactly which items need to be checked. Can anyone provide a list of Schedule C items to be checked?

This is my third Mercedes (wonder why I did not learn my lessons) and my last. Car is great when everything is working. However, reliability is a big issue. At 36K miles, 5 years old, engine light came on with code 1200 and 1208. It requires the whole engine to be removed to replace the balancing shaft. This is a common problem on E350. MB even have a service bulletin for this repair. ...

my car has died 4 times in two months been in the shop and they want to give me something to charge the battery. They claim that I don"t drive the car enough to keep a charge. Not happy with the 2011 E350 at all
