2009 Mercedes-Benz E350 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.

Failed Gateway Module May Cause Lack of Audio/Cell Phone Functionality

Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.

Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Is there a way to access outside air without engaging the compressor on my 2009 (1 answer)

I had a 2000E320 with an "EC" setting which allowed me to bring in outside air when the weather was pleasant without engaging the compressor. Does my 2009E350 have that? Can I turn on the heat without the compressor being engaged?

I HAVE BEEN HAVING TOO MANY PROBLEMS!!! MY E35O KNOCKS WHEN IT IS FIRST STARTED AND EXHAUST SYSTEM RATTLES. THESE PROBLEMS STARTED SIX MONTHS AFTER PURCHASING THE CAR. SERVICE DEPT CLAIMS THEY DO NOT HEAR THE KNOCKS OR RATTLES AND CANT FIND ANYTHING WRONG!! IVE TAKEN IT IN THREE TIMES FOR THESE SAME PROBLEMS. I AM STILL HEARING THESE KNOCKS AND RATTLES, SO FRUSTRATING!
I believe this is the best car on the road. I traded this in just a month ago for a 2010. It is so great.
