Vehicle Shudder Problems of Mercedes Benz C250

I was on I-95 and the car just started shaking and would not accelerate,very dangerous. The car also has a dangerous lag when trying to accelerate. I was trying to accelerate making a u turn to on coming traffic and the car wouldn't accelerate nearly causing a catastrophic life threatening accident. I have had my car at the dealership for 3 months trying to fix the problem and to date every time I get it back the same thing happens. My paperwork is with my car that has been at the dealership since for 3 months.

When accelerating at highway speeds (mostly) check engine light comes on and car shakes. If you pull over and restart the car most of the time the check engine light goes away. The engine error code (from mercedes) is p03001 which is a cylinder misfire. I purchased this car brand new and have had it at the dealership 8 times now for the same problem. They have replaced the fuel pump and injectors and problem still persists. Mercedes dealer is telling me there is nothing wrong with the car and they can't duplicate the problem after a week with the vehicle. The car is very dangerous to drive. This has happened to me no less than 20 times in 2 years of owning the vehicle. My son has been in the car with me several times when this has happened and it is a safety hazard to be at highway speeds and the car can no longer accelerate and starts to decelerate. Mercedes needs to do something about this before someone (namely me) dies because of this known issue. They have known about this with an internal document since October 2012 yet they continue to ignore the problem.
