My vehicle has about 68k miles, while driving on freeway all of sudden the car engine started to shake and check engine light came on dashboard. This engine shaking would stop when vehicle was being driven at high speed. Upon returning home I checked the DTC codes and had P300, P301 engine misfire codes. My mechanic suggested to have spark plugs and Ignition coil#1 to be changed. I bought new plugs from dealer for the replacement. When my mechanic completed this repair bit noticed vehicle still had misfire. He conducted compression test and found only 20PSI pressure is cylinder 1 and suggested a tear-down or engine replacement. I talked to another shop and described the issue and was informed that this is a common issue in Mercedes E300 to develop misfire in either cylinder 1 or 2. I found similar issues described by many owners on various forums online as well. Currently Mercedes has no recall for this issue.

Code P052E after oil changed. seems to happen often judging my forums.
My car is not accelerating when I shift into drive or reverse. It says “reversing not possile-service required” error. Out the blue. There is a known recall on these model cars but Mercedes benz is saying its vin specific and mine is not covered even though I am experiencing the exact same issue. Recall date- 2017-02-07 Recall no. 17V078000
See attached document for complaint.

The vehicle is getting stuck in parking and can not shift out of park. The issue first happened at the dealership when looking into an auxillary battery issue which has since been resolved. After over 30 minutes of trying to resolved the dealer was able to get the vehicle off the lift and switch the gear back into drive. Since then two days later the batteries were replaced and the same issue happen again (stuck in park) and now I see a transmission light on as well. I am not sure if the dealership noticed this when they had the issue in the shop. There was a previous transmission recall on the vehicle, which Mercedes said was previously addressed. My concern is that this can happen while driving which would be an extreme safety risks to myself and others. I don't believe I had any gear shift repairs since I owned the vehicle and the recall for my specific VIN may have been missed or not fully addressed. As of now I am unable to operate the vehicle and would like a recall reissued to resolve the problem. Thank you in advance for your assistance.
