On August 4th, 2018, September 21st,2018 and January 10th, 2019, my 2016 Mercedes-Benz gla 250 shutdown in the middle of the road. Specifically, in all 3 occasions mentioned above, my vehicle shut-downed and became disabled and non-operational, abruptly and without any warnings while driving. The occurrence on September 21st, 2018 was the most severe and happened during rush hour on I-93 where we almost got hit by incoming traffic from both directions. It is a miracle that nobody was hurt. Since the car had stopped in the middle of the highway, a state trooper forced me to have my car tow and not wait for my own aaa towing service which I had already called for assistance. The constant and real threat that the car can shut-down at any given moment while in operation created and imposed a major psychological burden to me and my family. It was mentally draining and exhausting to think that at any moment we can get into a fatal accident. The though alone, of such a potential tragic incident forced us to minimize the use of the vehicle and look for alternative mean of transportation. As a result, we were forced to purchase another car while the Mercedes has been idle and not used for the last few months. I have attempted to talk to the dealership, Mercedes-Benz financial services, Mercedes-Benz usa, Mercedes-Benz customer service and other departments of Mercedes-Benz but nobody was willing to listen or help me.
