2006 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 engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
The relay which turns the airmatic suspension pump on may fail causing the pump to run continuously. This can result in failure of the pump motor or a dead battery as the pump motor will continue to run after the car is turned off. Also, Worn airmatic pump mount bushings can causes noises in the front axle while driving on bumpy roads or a buzzing noise while the pump is running.
Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.

2006 Mercedes-Benz E350 Reviews
Purchased 2006 E350 with 55K miles in 2009. Loved the ride and the handling. Great car for my sales job. At 110K miles in 2011, car began to shimmy on a cold start. In later weeks, the car would shake violently on start up. Was told that it was a "balance shaft rotor", a small part about the size of a lipstick case deep inside the engine. Apparently for 2006 and other similar years this part was made of a softer metal. It would warp over time and cause the out-of-balance shaking to where the car was undriveable. Had 3 estimates from $5500 to $7000 to remedy. Bit the bullet and had it repaired by a buddy in Cleveland for $4500 who shot this video of the project http://youtu.be/fugJe-sG_fg Great car, but emotionally taxing repair. Good luck.
Bought car brand new in 2005. Have the same issue as others with Engine Check light due to balance shaft gear wear, requiring pulling the engine and replacing the balance shaft - at a cost of about $5500.
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?
I have had this care for 3+ years now. shortly after i bought the car i went into the dealership and i was told that i issues with the engine belt or something like that. i called warrenty dept and they would not cover the repairs. After going on line i realized that a few people had the same issues. I had purchased the car and taken it to the dealer ship to have it checked and i was told its in excellent shape.
I spent over $4000 dollars in repairs .. mercedez Benz has really bad customer service.
Great car for the money.
