 My wife was driving my ml350 on the freeway with my 7 year old son in the back. she said the vehicle started to shake in an unusual way so she decided to get off at the nearest exit and when she applied the brakes on the off ramp the car's engine stopped. engine light came on, dash read inoperable yet all the electrical was still on. she tried to turn the key and restart it but the car would not start. before this incident we had not experienced any problems. this is a 2012 model with just over 21,000 miles and was just serviced two weeks prior to the incident . it happened all of a sudden. the car was hit by another vehicle- rear ended with both my wife and son still in it.

 This happened as a new car, only now, after it happened about 5 or 6 times, we came to know this weired and dangerous problem-it loses the power at a stop; at red light, and even when we tried to start to move. when it happened, at first several times, we were thinking maybe i did something, after 5 to 6 times happened to me and to my wife, we just came to understand it is such dangerous problem. now, it happened again on friday and we went to the mercedes dealer, we came to know more, many happen like this, we are not the first; mercedes no solution, even they tried to find. so far, still no solution at all. the service guy declared that it only stopes at a stop!! they cannot do anything as mercedes still no solution!! will anyone drive such a weird car it stopes you at stop?? what happen if it stops you on the middle of the high way?? what will happen if somebody hit you from the back??

 Vehicle loses power after a few hours of driving. this problem does not show any error message on the dashboard, and the dealer cannot fix this problem after multiple attempts. last trip to the dealer which was 2 weeks ago, they insisted that nothing was wrong. here are examples of how serious the problem is, i was stranded and had to shut the car down for 30 - 45 minutes to let the car reset before continue driving. i was stranded on grapevine while driving back from san francisco to los angeles. the car could barely pull itself up the hill, and freeway 5 was under construction without much service lane that i can pull out. i got lucky and got to pull out before big rig slam into my back. this car will sporadically loses power on surface street which almost landed me into a head on collision while trying to make left turn across oncoming traffic because it will not move forward. currently, my car has about 8000 miles. i have been contacting mbusa, but there is no sense of urgency on their end. i filmed and took photos while the problem is in session because car computer will not log any. http://www.youtube.com/watch?feature=player_embedded&v=opqqfzt8zow http://www.youtube.com/watch?feature=player_embedded&v=uzedc-tncsu http://www.youtube.com/watch?feature=player_embedded&v=m_zwnzwz_ly i have a bit more videos and photos, but they are just the repetitive of what i posted above. i posted pictures on the mbworld forum. http://mbworld.org/forums/new-m-class-w166/466026-so-many-problems-my-2012-ml350-bluetec.html [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr
