Open the full vehicle complaint log (all categories)While driving the car shuts off and unable to restart. It will turn over but not remain started enough to move the vehicle. I did notice it jerk when speed was increased a few times before. Fuel pump was replaced less than a year ago according to Mercedes in Tuscaloosa Alabama. . After a certified Mercedes mechanic inspected the vehicle I was told it was the fuel pump once again. $4000+ later and I am having the same issue. Very frustrating to be stranded with my kids in the car.
The car shakes, vibrates and has rough idling. My engines stalls when it is at low rpm. I am afraid that if this is not fixed a fuel leak could occur in the presence of an ignition source, such as hot engine or exhaust components, which could increase the risk of a fire
