2009 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.

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.
