On Three (3) occasions, my engine has Stopped while the car was in gear and in motion. I was at great risk when this happened twice on August 7, 2024 while in traffic and my car stopped in the middle of traffic. One time I was able to coast into a parking lot. However, the second time the car stopped in the traffic lane. I was very lucky not to have been hit in the rear. In each case, I was able to restart the engine. One time I received a "Malfunction" notice on the dashboard. I immediately took the car to a Mercedes dealer for evaluation on August 8, 2024.. Dealer found Diagnostic Code P060C00 and did a "Standstll Adaption". On September 29, 2024, the engine once again stopped running while the car was in Reverse gear (Third Time) and I was backing out of a parking space. No malfunction notice appeared on the dash. I have an appointment on September 3, 2024, with the Mercedes dealer to leave the car. In all three case there has been No warning that there was a problem. The engine simply sputters and stopped. Only one "Malfunction" has appeared after the engine has stopped. The question on "speed" was not answered as I was in Stop and Go traffic on the first two times the engine stopped.
This has happened once before and I reported it then. This time I was stopped at a stop light and when I pressed the accelerator to go when the light turned green, the engine was off and would not go. The screen only said "malfunction" and no error codes (as before). I pressed the start button to turn the car off and then restarted it. It was fine after that. I have left a message with my service agent at my Mercedes dealership. I had previously told them that this had happened before. I am concerned about the safety of a car the stalls like this. Please investigate. I see other reports about this from E class car owners on line in various forums.
I purchased an E450 Mercedes before reaching my first service appointment while driving my two daughters home from school the car began to shake uncontrollably, lost power, and then the engine light and oil lights came on. The car was towed to the manufacturer dealership for repair. It was determined that the piston number four was broken and the engine needed to be completely replaced. Less than two months after having the entire engine replaced the car broke down again with a similar shaking. This time one of my children and their friend were in the vehicle with me. The car was towed back to the dealership where they said the fuel pump went out and needed to be replaced. When I arrived to pick up the car, the technician pulling the car around noticed the shaking and the engine light on again. I did not leave in the car. The dealer kept the car to further investigate why the engine light was on again. Two days later they called to say they’d been driving the car around to “air it out” as air must have been trapped in the fuel system and that nothing further needed to be done. I am not confident that this vehicle is safe to drive or properly repaired. I’m also not confident that this vehicle doesn’t have other unknown issues that will arise overtime. It’s unsafe to drive children in this car. I still have not even reached 10,000 miles on this car.
I had just left home and was about two blocks from my house when the engine stopped running and the word “malfunction” appeared on the display. It would not restart until I hit the off button and then I restarted it. Definite safety issue if I had been on the freeway or a busy street.
