2007 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 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.
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
Lack of audio or cell phone functionality may be related to the failure of the audio gateway module.

2007 Mercedes-Benz E350 Reviews
I love my car...it has a great ride, appearance, is reliable and comfortable. For the past few weeks, it has had an unusual problem. I drive to shop or do errands. After returning to the car (apx 20 minutes), I start the engine and it immediately turns off. A second try is necessary to get going. The dealership has no idea why this happens and their service manager and service technician have witnessed the problem...but somehow they can't reproduce it and don't know how to fix it. I am open to helpful suggestions.
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. Knowing MB's reliability issues, I had purhased the factory extended warranty. Otherwise, I will get hit with a $5000 repair. Engine light came on again 2 weeks after the repair. It is at the dealearship at the moment. Not sure what it is this time. I have 18 months warranty left and will definitely sell the car before the time comes.
MB doesn't seem to care about reliability. The 3 generations of C and E class I have owned, there are problems one after another. MB needs to hire the engineers from Toyota or Honda.
I have owned Audi, BMW, Acura and currently a Toyota and a Porsche. MB is the least reliable and expense to repair.
Do yourself a favor, keep a MB only if it is under warranty and you have free time to visit the dealership frequently. If your dream car is a MB, watchout, it can turn into a nightmare.
I jokingly said I'm going to trade my Tacoma TRD for a Mercedes. I entered the lot and drove a 2007 E350 but it ran sluggishly so i passed as it seemed like it was running like a lemon. Found a sport package model with all the upgrades for $32,000 at a sister dealership. Test drove and purchased as it was an amazing car. Certified @20k miles, 2 years old, and over 50% off MSRP? How could I NOT buy it! I think certified is the way to go as I am loving this car more and more everyday and I have had it a year now. it is fast, agile, and looks classy. CD changer and stereo kind of suck if you like bumping systems you will need to drop a sub in the trunk and bounce it through the ski pass through. Every time I walk up I think damn this is a nice car then I get in with a smile because it's mine.
